HOME - RECENT CHANGES
• Lists all the changes in reverse chronological order

SEARCH
14
SEARCH
• by string: the user can specify if the system should search by exact match, beginning with, contains or fuzzy
• by URI or term code; or by range of term code (e.g. between 123 and 9876)
• by classification schemes
• by creation or modification date
• by specific relationships (e.g. search all concepts using the “has_pest”)
• by status, language
• by notes/attributes
15
SEARCH CRITERIA• Exact match (“water” will find only water)
• Starting with (“water” will find “water”, “water management”, and “watergate”)
• Contain (“water” will find “water”, “water management”, “inland water”, and “watergate”)
• Exact word (“water” will find “water”, “water management”, “inland water” but not “watergate”)
• Case Sensitive (“ABc” will find only for the word “ABc” and not “abc”
• Include Description
– Search also content of definitions, images, editorial notes, scope notes
• Include Spelling Variant
– Search also on different spelling variants
16
CONCEPT MANAGEMENT• Visualize / Navigate Concepts
– depending on the access level, user can edit
• Show selected concept details
– all terms and other information
• Show selected concept relationships
• Delete concept
• Can view the URI of the concept enabling ‘Show URI’ option
17
CONCEPT MANAGEMENT
18
ADD/DELETE CONCEPT
• Add term to the newly created concept in one language• Can delete the concept and all the relationship associated with that concept
19
CONCEPT RELATIONSHIP
• Can create the concept-concept relationship• Inverse relationship is also created
automatically– Ex: If we create A affect B, then B is affected by A
relationship is also created
20
CONCEPT IMAGE
• Name of the image with description
• URL will point to the image which will open in an external
• Provide the source of the image
• Can add more translation in different language
21
SCOPE/EDITORIAL NOTES• In Editorial Notes, we can post the modifications
made to the selected concepts• In Scope Notes, we can post information for indexing• Both can contain multiple values in multiple
languages
22
CONCEPT DEFINITION• Add definition to the selected concept • Add translation in different languages• Provide the source of the definition• Creation and modified date are set automatically
23
TERM MANAGEMENT
• Visualize / Navigate Terms – depending on the user access level and role
• Show selected term details• Show selected term relationships• Show term variances• Add/Edit/Delete term
24
ADD/EDIT/DELETE TERM• Term actions will be associated to the selected concept • Term can be created in different languages• Term can be set as preferred or non preferred• An option allows preferred terms visualization only in the concept tree
browser
25
CONCEPT GRAPH VISUALIZATION
26
RELATIONSHIP MANAGEMENT
27
LABEL/DEFINITION
• Can add/edit/delete the label for relationship in multiple languages
• Can add/edit/delete definition of the relationships in multiple languages
28
PROPERTIES/ DOMAIN & RANGE
Can assign functional, transitive, inverse & symmetric properties to the selected relationship
Only functional properties can be selected for data type properties
Can specify the domain & range
29
VALIDATION
• Allows to verify the new concept/term/definition/relationships/notes/attributes created, edited or deleted.

EXPORT
• Formats– SKOS– RDBMS-SQL– TBX– OWL
33
CLASSIFICATION SCHEMES
• Add/Edit/Delete different classification schemes
• Can create new category or assign existing domain concept to the classification schemes
• Mapping categories to domain concepts is possible
34
USER MANAGEMENT
• Manages user detail information.• Assign each user different group privilege and languages.
35
GROUP MANAGEMENT
• Manages different groups, their permission and members.• Assign allowed actions for each group.
36
CONSISTENCY CHECK
• Checks if there is any inconsistency in the model data.
37
SYSTEM PREFERENCES
• Manage user information/preferences• VocBench interface
38
RSS
• All the changes on the VocBench content is published through RSS.
• Helps people who regularly use VocBench to stay informed about the changes.
• Shows

WEB SERVICES
• AGROVOC Concept Server is accessible via web services, which can be called from any client application.
• The web services are realized on Apache Axis running on Tomcat.
• Using web services, –helps third party application for easy access to WB content–changes on the content of AGROVOC Concept Server can be
accessed immediately–reduces the time and effort necessary to download and
incorporate the latest version of the AGROVOC Concept Server content into applications

VocBench 2.0• VB 2.0 will natively support SKOS• Separation of the business and presentation layers from the data layer• This allows VB to be attached to any SPARQL-compliant triple-store
database (Sesame, Jena, Allegrograph, OWLLim)• First release of VB 2.0 will retain the same interface as that of VB
1.0• VB 2.0 will incorporate all the functionalities available in VB 1.0• Multi-user support, roles and right administration, and publishing work
flow management will inherited from VB 1.0.• Current Protégé implementation of VB 1.0 will be replaced by Semantic
Turkey • All the business logic and data access layers related to ontology
management will be handled by Semantic Turkey

SYSTEM OVERVIEW• Front End
– GWT/GWT Incubator• Google Web Toolkit
– Graph Visualization• Java Applet
• Middle ware– Service wrapper layer
• separates client and service layer• allows to switch between old Protégé implementation and Semantic Turkey
– Semantic Turkey/OWL Art API– Gilead
• integrating GWT and Hibernate
• Back end– Administrative DB : MySQL– Triple Store: Sesame/Jena/Allegrograph,..
51
Semantic Turkey/OWLArt API• Semantic Turkey provides
– business logic including OWL and SKOS support, – import for OWL and SKOS, – triple-store agnostic design and – an OSGi-compliant plug-in architecture.
• Semantic Turkey uses the OWLArt API which is already partially integrated within VocBench.
• OWLArt API offers– a basic RDF triple query and SPARQL access layer, which need to be
implemented for any specific triple store– methods more closely connected with operations related to the standard
vocabularies of the RDF family (from RDF to RDFS, OWL, SKOS and SKOS-XL).
