2. awards

2.1 Marco Cadoli Distinguished Dissertation Award

On June 25, 2009, Marco Montali is honored with the “Marco Cadoli” DistinguishedDissertation Award, awarded by the Italian Association for Logic Programming tothe most outstanding italian PhD theses focused on computational logic, and dis-cussed between 2007 and 2009. The evaluation procedure has been carried out by aninternational panel of leading experts7. In the following, two of the reviews are attached.

Robert A. Kowalski - Professor Emeritus, Department of Computing, Logic and Artificial Intelligence Group,Imperial College London, UK

I decided to read the entire thesis, because it contains so much interesting and important material.The thesis contains both wide-ranging background work and the original contributions of the thesis itself.The contributions of the thesis include not only significant contributions to theory, but also importantwork on practical implementation and applications.The subject of the thesis, the Specification and Verification of Declarative Open Interaction Models, isexceptionally broad and outward-looking. The thesis bridges the gap between the methods of Com-putational Logic developed mainly in Artificial Intelligence and the tools and techniques developed insuch otherwise unrelated domains as Business Process Management, Clinical Guidelines and CareflowProtocols, Service-Oriented and Multi-Agent Systems. Most PhD theses are restricted to a single domainand narrowly deal with only theoretical, implementation of application issues.In addition to the original work presented in the thesis, the thesis includes a analysis of and comparisonwith related work, including the use of Linear Temporal Logic and Model Checking. Montali presentsconvincing evidence for the benefits of his approach, but is modest in his acknowledgement of itslimitations and in his assessment of related work.This is one of the best PhD theses I have seen in a long time.

Wil M.P. van der Aalst - Full Professor, Department of Mathematics & Computer Science, Eindhoven Universityof Technology, Eindhoven, The Netherlands

The thesis is truly excellent and I would like to nominate the work for the best dissertation award.The work covers a broad area and provides deep and interesting results. Moreover, the work is supportedby a nice set of tools. The framework consists of ConDec, CLIMB (a subset of SCIFF), g-SCIFF, andREC. It is shown that CLIMB is more expressive than LTL and this is demonstrated using ConDec.This is supported by checks at design-time and run-time. Moreover, the approach provides all kinds ofadditional support. Very interesting is the ability to discover declarative models. This is challenging andhighly relevant.The thesis work has resulted in a large number of high-quality publications. Moreover, the work hasbeen presented at top conferences.

4. research activity

The research activity of Marco Montali focuses on Artificial Intelligence. He is workingon theoretical, methodological and experimental aspects related to the exploitation ofcomputational-logic based languages, together with their corresponding automatedreasoning techniques, for the specification and verification of interaction models inthe context of event-based systems. Among the application domains targeted by hisresearch we find business processes, clinical guidelines, service-oriented and multi-agentsystems.

4.1 Declarative and Open Approaches for Knowledge Representation and Automated Reasoningin Event-Based Systems

The advent of distributed and heterogeneous systems has laid the foundation for thebirth of new architectural paradigms, in which many separated and autonomous entitiescollaborate and interact to the aim of achieving complex strategic goals, impossibleto be accomplished on their own. A non exhaustive list of systems targeted by suchparadigms includes business process management, clinical guidelines and care-flowprotocols, service-oriented and multi-agent systems. All these systems shift the focusfrom the single participants to their interaction and cooperation. Each (inter)actionis typically modeled and traced in terms of events, which characterize the observabledynamics of a specific system’s execution. This is the reason why such systems can begrouped under the umbrella term of event-based systems.

In this context, Marco Montali is studying new paradigm and modeling languages,able to suitably mediate between compliance support, used to regulate the participantsbehavior, and flexibility, intended as the freedom of choice left to the interacting entities,allowing them to take opportunities and exploit their competences and knowledge.In order to provide an answer to these demands, Marco Montali is investigating howto complement the classical workflow-like interaction specification languages with adeclarative and open perspective [P.2], [P.1]. Declarative, in order to help the modeler inthe specification of the behavioral constraints that must be respected, without explicitlyenumerating a-priori a predetermined and rigid set of acceptable flows. Open, to the aimof leaving participants free to execute actions that are not explicitly forbidden, which isa fundamental requirement inside environments where the participants’ knowledge isincomplete and constantly subject to updates as new events occur.

More in details, the research activity of Marco Montali focuses on the following topis:

• study of graphical languages for the specification of interaction models, payingparticular attention to their usability;

• synthesis of suitable automated translation mechanisms able to analyze a graphicalmodel and generate a corresponding logic-based formal representation;

• definition and development of automated reasoning techniques for supporting theverification, execution and analysis of interaction models along the entire lifecycleof the targeted systems;

12

• application of such languages and reasoning techniques in the context of businessprocesses, clinical guidelines, service-oriented and multi-agent systems.

4.2 Logics for the Formalization of Interaction Models

It is of key importance that interaction models can be specified by domain expertswithout IT skills, but it is also fundamental that such models are equipped witha corresponding formal representation, providing an unambiguous semantics andsupporting the application of rigorous reasoning techniques. In this respect, MarcoMontali is applying diverse logic-based frameworks for the formalization of interactionmodels.

In [P.2], [P.1] e [P.3], he investigated the adoption of the SCIFF language8 for thespecification of interaction models with an open and declarative flavor. SCIFF isa framework, based on abductive logic programming, that constrains the possiblebehaviors by means of declarative (reactive) rules, expressing what is expected (not) tohappen when some state of affairs is reached. It is equipped with a declarative semanticswhich gives a formal account to the notion of compliance of a given system’s execution(i.e., an execution trace) with respect to the specified rules. It is highly expressive, beingbased on a fragment of first order logic: it supports variables and unification, andvariables can be subject either to CLP9 constraints and Prolog predicates. The abductivenature of the language fits with the incomplete and constantly increasing knowledgethat the participants have during the execution. The language is associated to a familyof proof procedures that can be exploited to statically verify a designed model, to carryout monitoring and run-time verification during the system’s execution as well as todeal with a-posteriori analysis.

The research activity of Marco Montali has not only dealt with the adoption ofSCIFF, but also on the comparison between SCIFF and other state of the art logic-basedlanguages, in particular Linear Temporal Logic (LTL). In [P.3], both logics have beenproposed as suitable approaches to interaction modeling; the comparison is carriedout by taking into account their features as well as their associated reasoning andverification methods. [P.2] contains instead a more theoretical investigation, whichrelates the notion of entailment in SCIFF with the one of LTL, and formally comparesthe expressiveness of the two logics.

Even if SCIFF is a very rich language, it does not support the explicit characterizationof the state of affairs in which a system’s execution can be, nor it can accommodatethe specification of properties (fluents) that vary over time, as events occur. Suchrequirements are instead covered by the Event Calculus10 (EC), one of the most well-known and acknowledged framework for modeling and reasoning on actions and theireffects. Unfortunately, the EC-based proposals in the literature cannot cover all the

13

forms of reasoning enabled by SCIFF; furthermore, in many cases they consist of ad-hocimplementations or solutions that rely on extra-logical constructs.

In order to overcome these limits and to combine the advantages of SCIFF andEC, in [P.41], [P.14], [P.7], [P.9] Marco Montali and coauthors have proposed a SCIFF-based axiomatization of the EC and studied its formal properties. This is, as faras we are concerned, the first attempt to provide a reactive axiomatization of theEC without employing extra-logical constructs. Thanks to such an axiomatization, itbecomes possible to study the formal properties of the calculus (such as soundness,completeness, termination and irrevocability [P.9]) and, at the same time, to apply theEC for monitoring a system’s execution. In particular, the occurring events can beacquired on-the-fly, leading to a dynamic update of the fluents’ truth values.

4.3 Business Process Management

In [P.2] e [P.1], Marco Montali has proposed a framework called CLIMB (ComputationalLogic for the verIfication and Modeling of Business Constraints), which combines graphicalmodeling, logic-based languages and automated reasoning techniques for the rigorousspecification of open and declarative interaction models, providing support during theirentire life cycle.

CLIMB adopts an extended version of the graphical ConDec11 notation for thespecification of behavioral business constraints. ConDec is a graphical constraint-basedlanguage for modeling flexible business processes. In CLIMB, ConDec is extended withquantitative temporal constraints (such as delays, deadlines and latencies), non-atomicactivities, data and data-aware conditions. All the constructs of (extended) ConDec areautomatically translated into SCIFF rules and EC theories, making it possible to applythe proof procedures developed for SCIFF also in the context of ConDec.

More specifically, reasoning in CLIMB exploits a family of proof procedures forthe static verification of properties (g-SCIFF proof procedure), run-time verification &monitoring (SCIFF proof procedure and EC), process mining (SCIFF proof procedure,Prolog and inductive logic programming).

static verification with g-sciff Static verification is applied ex ante, duringthe modeling&design phase, to the aim of guaranteeing the correctness and consistencyof the produced models, and of detecting design errors which, if encountered at run-time, could be difficult to manage or even compromise the functioning of the system.

g-SCIFF follows a simulative approach based on abduction; in other words, it employsthe rules of the model trying to generate execution traces that are at the same timecompliant with the model itself and (do not) entail an (un)desired property.

The applicability of g-SCIFF to the static verification of ConDec models has beenstudied following a theoretical ([P.2], [P.1] e [P.5]) as well as an experimental approach,through the definition of some benchmarks. Such benchmarks have been exploitedto assess g-SCIFF’s performance and scalability, and to compare its behavior withsatisfiability checking via model checking techniques, taking into account state-of-the-

art explicit and symbolic model checkers, as well as SAT-based methods ([P.3], [P.17],[P.42], [P.5]).

operational decision support Complex business processes, that involve theparticipation of domain experts, are characterized by an high degree of unpredictability:it is impossible to foresee a-priori which behavior will be exhibited by the interactingentities in a given situation. Hence, automated reasoning techniques must be developedto constantly monitor a running execution of the system and promptly detect deviationsbetween the actual behavior and the prescriptions of the model.

The SCIFF language is associated to a proof procedure (also called SCIFF) that is ableto dynamically acquire a running execution trace (or analyze a-posteriori an alreadycompleted trace), checking whether it complies with the specified rules. In [P.2] e [P.1],it has been demonstrated how the combined use of EC and SCIFF (called REC - ReactiveEC) can be successfully employed to monitor a running process and dynamicallycompute the effect of events on the modeled business constraints, as well as promptlygenerate alerts as soon as a constraint becomes violated.

In the context of a collaboration with the Eindhoven University of Technology, MarcoMontali is applying REC to provide operational support12 to business processes. Op-erational decision support aims at applying process mining techniques during theexecution, providing assistance on-the-fly, during the execution of business processes.

In particular, he is investigating the use of (R)EC and LTL, together with reactivereasoning procedures and automata-based techniques, for addressing the run-timeverification and monitoring of business constraints and rules. An EC-based operationalsupport provider has been implemented inside ProM 6, the latest version of the widelyacknowledged ProM process mining framework13.

process mining A plethora of event-based systems (such as business processmanagement systems) store the events occurred during their executions inside aninformation system. All these event logs can be analyzed ex-post in order to extractuseful informations for business managers and practitioners, supporting them in deci-sion making and trend analysis, in the improvement of the company’s organizationalstructure and its business processes.

The algorithms, techniques and tools focusing on the extraction of information fromevent logs fall under the umbrella term of process mining. In this field, Marco Montalihas mainly worked on two different but interconnected research lines:

• classification of the execution traces contained inside an event log, based on theircompliance with business rules and constraints;

• discovery of (SCIFF and ConDec) declarative models starting from a set of exe-cution traces which have been previously labeled as compliant or non compliantwith respect to a given classification criterion; the discovered model is able tocorrectly discriminate the two sets.

Concerning the first issue, a pseudo-natural language syntax inspired by SCIFF andConDec has been defined in order to specify ECA-like business rules. A ProM plug-inhas been implemented to support the configuration of business rules and to concretelyhandle the classification task. The user interface has been implemented in JAVA, whilethe classification engine is written in Prolog. Details of the approach and the plug-incan be found in [P.43], [P.29] e [P.1]. The tool has been applied in different applicationdomains. In particular, it has been employed in the context of the FIRB TOCAI.IT italianproject to check the execution traces of a leading company in the manufacturing industry[P.29], and to provide support in the analysis of chemical processes for wastewatertreatment [P.44], as part of a complex event processing architecture combining sub-symbolicand symbolic artificial intelligence techniques [P.6].

For what regards the second issue, in [P.46] e [P.15] an inductive logic programmingalgorithm has been defined, whose aim is to discover SCIFF and ConDec specifications.More specifically, the algorithm targets the discovery of SCIFF specifications; thepossibility of translating ConDec into SCIFF is then exploited in the opposite way, toobtain a graphical representation of the induced models. [P.10] exploits this approachas the core part of a declarative process discovery framework implemented in the formof a ProM plug-in. The tool supports the user in the data preparation phase, wraps thediscovery algorithm and then takes care of generating the final ConDec diagram.

4.4 Service Oriented Architecture

In [P.3], Montali and coauthors have pointed out some critical limitations of closedand procedural languages (such as WS-CDL and BPEL) in the specification of servicechoreographies. They have shown how such limitations can be overcome by exploitingDecSerFlow, a ConDec-inspired graphical language for the declarative specificationof service flows. The usability of DecSerFlow has been assessed by using Green’scognitive dimensions14. Moreover, suitable mappings have been presented in orderto automatically obtain a logic-based specification from a DecSerFlow diagram; inparticular, LTL and SCIFF have been chosen as the target formalisms, showing theiradvantages and lacks.

SCIFF has been proposed not only as a formal language for the specification of chore-ographic constraints, but also to cope with the modeling of service behavioral interface,consequently enabling the application of the SCIFF and g-SCIFF proof procedures forstatically and dynamically reasoning on service compositions.

(semantic) web service discovery and contracting The discovery andcontracting of (web) services is nowadays a challenging and hot topic. With theexponential growth of the services made available on the Internet, there is an increasingdemand of smart techniques for finding services able to effectively accomplish a givengoal. Their usefulness is twofold: they constitute the basis for the development ofadvanced service registries and search engines, and at the same time they are the corepart of (dynamic) service composition frameworks.

14 T. R. G. Green. Cognitive Dimensions of Notations. People and Computer V, pages 443–460, 1989.

16

To enable such techniques, many authors are proposing to extend the interfacesexposed by services with informations dedicated to characterize their semantics, interms of the meaning of the exchanged messages and data, as well as concerning theirpublic behavior. In the last years, Marco Montali and colleagues have investigatedthe application of the SCIFF framework for the flexible specification of the services’behavioral interfaces and for reasoning on service composition to establish, a-priori,whether a possible course of interaction exists, such that the behavioral policies of bothservices are respected and some desired goal is reached (see [P.37] and [P.27]). This taskis usually denoted by contracting.

In [P.18], these ideas are exploited towards a service discovery engine in which theclient’s requirements are matched with the services’ specifications using not only theirsyntactic operations (UDDI), but also their behavioral policies.

The approach has been further extended in [P.38] and [P.16], introducing also onto-logical issues (such as for example meaning-based instead of syntactic-based matchingbetween the terms of discourse). Both the behavioral aspects as well as the semanticsof the involved messages and data is taken into account during the interoperabilityverification, in a unified manner. The framework exploits SCIFF for reasoning on thebehavioral rules of services, and relies on Pellet15 for what concerns ontological issues.

conformance with a choreography Service choreographies represent a pub-lic contract, shared among all the participating parties, which selects the possiblemessage exchanges that guarantee a correct collaboration. Thanks to choreographies,different companies can mutually benefit from each other’s services, agreeing on therules of engagement that must be respected during the interaction. In this respect,suitable reasoning methods must be found for verifying whether a given service caneffectively take part to the choreography playing some role, ensuring that its behavioralinterface respects all the choreography rules involving that role.

This problem is called conformance verification, and has been tackled in [P.49], [P.51]and [P.19] by modeling both the services’ behavioral interfaces and the choreographyconstraints as SCIFF rules. The conformance verification problem is tackled by aframework called Allows (Abductive Logic Web Service Specification), that combinesdifferent reasoning techniques to establish whether a given service can play somerole inside the choreography, assuming that all the other participating services willact according to the choreography. If the service passes the conformance test, it isguaranteed that it will correctly interact with any other service conforming to thechoreography. Such a test is more flexible than bisimilarity-based approaches, becauseit is not requested that a conforming service must exhibit a behavior that completelyoverlaps with the behavior requested by the choreography.

[P.3], [P.1] and [P.39] introduces an even more flexible notion of conformance. In thiscase, the choreography as well as all the services that must be composed are modeledwith ConDec constraints, and verification is carried out by translating all specificationsinto SCIFF (using the automated translation defined in [P.3] and [P.1]) and by applyingthe g-SCIFF proof procedure on the combination of all constraints. In this respect,conformance is evaluated by considering a complete grounded service composition

17

against the choreography. On the one hand, such a test is therefore less general thanthe one defined in [P.19]; on the other hand, it is more flexible, because it is able torecognize suitable compositions that do not cover the entire choreography specifications,but nevertheless can interact respecting the choreography prescriptions.

run-time verification and monitoring Run-time verification and monitor-ing are matter of the greatest importance in the context of service-oriented systems.Indeed, even in presence of static informations about the services’ behavior, it is notguaranteed that the behavioral interface exposed by a service effectively corresponds toits internal implementation. The only way to handle this issue is to continuously checkthe behavior of the service during its execution.

In [P.26], the SCIFF framework is exploited to dynamically check whether the mes-sages exchanged within a service composition comply with a given choreography. Theapproach is further extended in [P.25], where REC is adopted making the frameworkable to constantly provide a feedback that shows how the occurring events impacton the choreography constraints; furthermore, the detected violations can be explic-itly represented (i.e., reified) and used to generate alarms or trigger correspondingcompensation mechanisms.

4.5 Open Multi-Agent Systems

In the field of open multi-agent systems16, Marco Montali has contributed to thespecification and verification of interaction protocols, with particular emphasis onnormative and contractual aspects.

In [P.47] and [P.8], the SCIFF framework has been applied to the verification ofbusiness contracts, showing its expressiveness when capturing complex contractualclauses, discussing its inference capabilities and relating its language primitives todeontic operators.

The possibility of axiomatizing the EC in terms of SCIFF rules has provided the basisfor modeling, extending and monitoring interaction protocols based on commitments17,i.e. protocols focusing on the mutual obligations established between the interactingagents during the execution. A commitment states that a debtor agent is boundtowards a creditor agent, and must bring about some property to correctly dischargethe commitment. The theory of commitments specifies the states through which acommitment goes as certain events occur.

In [P.14], Montali and colleagues have taken advantage from the possibility of ax-iomatizing the basic commitments theory in the EC18, extending it with the temporalnotion of deadline. This opens the possibility of modeling commitments in which thedebtor agents must bring about a given property within a maximum timestamp, and of

16 Multi-agent systems in which agents can dynamically take part to or leaving the interaction, and in whichthere is no fixed and statically known set of agents, nor it is possible to access their implementation.

tackling compensation mechanisms triggered by the violation of a deadline. REC is thenexploited to dynamically acquire the events occurring during the interaction, computingthe current state of all the involved commitments. Finally, some interesting formalproperties of REC are presented, introducing in particular the irrevocability property.Irrevocability guarantees that the results computed by REC are always extensions (notrevisions) of the previous ones, provided that the event occurrences are time-ordered.

In [P.30], the theory of commitments is further extended embracing different possibletime-aware commitments. Two classes of time-aware commitments are introduced:existential commitments, whose property must be brought about inside a given timeinterval, and universal commitments, whose property must be continuously maintainedtrue during a given time interval.

In [P.40], an implemented tool for commitments monitoring is presented. Thereasoning engine of the tool makes use of REC and SWI Prolog, while JAVA is employedfor the acquisition of events and the visualization of the produced results.

In [P.24], the approach presented in [P.14] is integrated with the investigation pre-sented in [P.30]. A comprehensive framework for monitoring time-aware commitment-based interaction protocols is described, from theory (i.e., the EC-based axiomatizationof the time-aware commitments theory) to practice (i.e., the adoption of REC and of thetool introduced in [P.40]). The paper wins the Best Paper Award.

In [P.33], the monitoring of agent interaction protocols is focused on the notion of(dynamic) role. The EC is employed to model roles and their dynamics over time. Themembership to a given role at a certain time is combined with SCIFF rules to tacklealso behavioral rules, expectations, obligations and prohibitions that must be honoredby the interacting agents because of the role they are playing.

The invited presentation [P.34] summarizes the different research lines followed byMarco Montali and is colleagues on all these topics.

4.6 Combination Between Agent-, Service- and Process-Oriented Approaches

During his research activity, Marco Montali has identified synergies between openmulti-agent systems, service-oriented approaches and business process management.Such systems often share similar challenges, that can be successfully tackled withintegrated solutions.

In [P.48] e [P.7], constraint-based and commitment-based approaches are combinedin order to model service choreographies with a flexible, dynamic and adaptive flavor.Hard, flow-oriented constraints between activities are captured with ConDec, whilecommitments are adopted to deal with mutual obligations between services, as wellas to represent the compesation protocols arising from exceptional and undesiredsituations. SCIFF and the EC are used as a comprehensive unifying formal frameworkto cope with both aspects.

[P.45], [P.28] and [P.4] deals with the problem of representing and verifying agent-based software systems, taking into account requirements, agents’ goals and businessprocesses. From the specification point of view, the challenge is faced by adopting

19

the Tropos language and methodology19, extending the language with behavioralconstraints expressed in ConDec, with temporal aspects as well as data-driven choices.In [P.4], the g-SCIFF proof procedure is employed to verify a-priori the correctnessand executability of the specified models. In particular, the formal properties of theapproach are studied, identifying a class of (extended) Tropos models for which thetermination of the verifier is always guaranteed.

4.7 Clinical Guidelines and Care-Flow Protocols

The research activity of Marco Montali in the field of clinical guidelines started in 2005,when he became recipient of a Spinner technology transfer grant. During the project, hefocused on the representation of care-flow protocols (in particular screening processes)and on the compliance verification of the healthcare professionals with respect to agiven specification. A preliminary study on this topic is described in [P.22].

During the Spinner and the MEng projects, he defined a graphical language, calledGOSpeL (Guideline prOcess Specification Language), for the specification of the guide-lines’ activities and workflow. The language is block-structured, and supports atomicactivities, sub-processes, sequence connections, data-driven and deferred choices, paral-lel sections and cycles. Atomic activities and their data and resources are modeled withdomain ontologies specified by the user.

[P.50] e [P.21] describe a translation algorithm able to analyze a clinical guidelinespecified in GOSpeL and automatically produce a corresponding SCIFF-based repre-sentation. In this way, the SCIFF proof procedure can be adopted to deal with therun-time verification of the healthcare professionals, or the a-posteriori analysis ofalready completed execution traces related to the guideline’s application on differentpatients. A software prototype supporting the specification and automatic translationof GOSpeL models has been implemented in JAVA, relying on the Protege20 APIs forthe ontological part.

The comprehensive resulting architecture, called GPROVE (Guideline PRocess cOnfor-mance VErification), has been presented in [P.23], while [P.13] describes how GPROVEhas been exploited to deal with a real case study. In particular, GPROVE has beenapplied in the context of the cervical cancer screening process applied in the EmiliaRomagna region – Italy, to the aim of verifying the adherence between its concreteexecutions and the prescriptions defined by the regional Sanitary Organization.

In [P.31], GPROVE has been compared with GLARE21, in order to identify theirsimilarities and differences, as well as their advantages and lacks, and consequently laythe foundations for an integrated approach. The evaluation has been carried out usinga classification methodology well known in the literature.

20

More recently, the research activity of Marco Montali has focused on the integrationbetween flow-oriented and declarative guideline specification languages, capturing notonly the prescriptions contained in the documents produced by the sanitary organi-zations, but also the background medical knowledge. A first investigation on thesethemes can be found in [P.20]. The long-term purpose of this research line is to helpphysicians and the medical staff in the execution of guidelines, providing decision sup-port systems that suitably mediate between control and flexibility, and combining thegeneral prescriptions contained in the guideline with the specific context and situationof each patient.
