EVALUATOR

Usability and 3DVW3DAVI (IVQSS)

Virtual World 3D (VW-3D) is an advanced visual interface system

to the MATRIX 3 platform to represent in 3D the e-learning activity and related network

services for cooperative-works.

The web acts as a virtual Usability Lab and will allow the

analysis and testing of the usability level of different systems such as Learning

Content Management System (LCMS), authoring tools and

learning objects.

The IVQSS prototype is a Visual Query System developed at

ENEA's Usability Lab to access and query remote databases through the Web. The system allows to create and execute

queries to remote databases and to have a results visualization.

““The extent to which a product can be used by specified users to achieve The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified specified goals with effectiveness, efficiency and satisfaction in a specified context of use.” context of use.”


Why Usability?<<Let’s think about a financial society. Every day there are numerous accesses at the management page and there is a designing error in this page and it makes an average of 10 seconds of time lost.If this error repeats every day 20 times for a number of 10 staff-users with a cost of 40 euro per hour, the society has to pay 6700 each week and 70000 Euro every year with looses of 1750 working hours>>.

Architettura interna

• Il MM è strutturato con un’architettura modulare dove ogni singolo modulo ha una struttura indipendente che lavora in modo collaborativo con gli altri;

• Il modulo principale è costituito dalla classe Metasearcher, che si avvale della classe Tool che contiene gli strumenti per la gestione dell’XML;

• Il modulo Error e il modulo Log sono di supporto e sono integrati totalmente in ogni procedura o funzione del MM stesso;

• La gestione delle grosse moli di dati viene demandata al modulo Multiserver, il quale gestisce un protocollo di comunicazione tra le diverse istanze del MM presenti sui diversi server distribuiti sulla rete;

• L’interfaccia utente viene gestita dalla webform chiamata Wizquery, la quale non è semplicemente una pagina web, ma una struttura modulare conforme alle wizard di configurazione classiche delle applicazioni stand-alone che permette di inserire tutti i parametri per strutturare una ricerca in maniera sequenziale.

Il tutto è strutturato per operare in parallelo e abbattere i tempi di attesa Il tutto è strutturato per operare in parallelo e abbattere i tempi di attesa propri della rete Internetpropri della rete Internet

MMs – il Meta Motore standard

• MMs crea una collezione di normative di differenti BDN in modalità standard.

Il dimostratore è un estrattore di prima generazione in grado di interrogare le

form dei siti web secondo parametri predefiniti. Questo sistema è stato

utilizzato per inserire i risultati ottenuti nella BDN centrale;

• La caratteristica principale dell’MMs è quella di essere un’applicazione

configurabile unicamente dal programmatore stesso. L’obiettivo di questa

applicazione web è quella di ottenere l’estrazione più esaustiva e più

coerente delle normative presenti nelle BDN di riferimento.


Utilizzo delle form

Nelle pagine web i form sono elementi composti da diversi campi che consentono ricerche dettagliate nelle banche dati alle quali sono collegate, si è pensato quindi di sfruttare questi componenti per garantire al metamotore lo scaricamento di dati il più possibile attinenti alla nostra ricerca;

Per rendere i form utilizzabili dal metamotore si è realizzata un’interfaccia visuale di tipo wizard in grado di guidare l’operatore nella configurazione del form permettendogli di selezionare uno alla volta tutti i campi necessari alla ricerca.


Caratterizzazione Form

Una volta portate a termine la configurazione e salvati i dati il motore di gestione delle form genera un codice xml in grado di interfacciarsi con il metamotore, opportunamente modificato, che provvederà ad effettuare le richieste ed ottenere le pagine dei risultati;

Per poter gestire al meglio le pagine dei risultati è stato inoltre introdotto nel metamotore un modulo esterno in grado di prelevare dal web un file pdf e produrre in output un file html con il contenuto testuale di tale documento.


La validazione

• I test di usabilità (metodologia ENEA VENUS/Plus) eseguiti sul MM hanno riguardato gli aspetti funzionali del sistema a livello delle sue componenti di gestione (configurazione), interrogazione e interfaccia utente;

• I test sono stati svolti da 20 utenti (end users, esperti, sistemisti ENEA), in regime di osservazione diretta, con assistenza attiva riguardante i compiti assegnati sulle schede di lavoro;

• I task hanno riguardato la gestione del MM da parte dello staff, la gestione delle basi di dati (Data base centrale) e file di esportazione dei dati in formato XML; l’interrogazione predefinita, semplice, avanzata (Interfaccia lato utente del MM);

I test di usabilità svolti hanno consentito di valutare positivamente le I test di usabilità svolti hanno consentito di valutare positivamente le funzionalità del MM;funzionalità del MM;

• Una funzione generica di estrazione dati indipendente dalla fonte, dalla struttura informativa e dal set di informazioni richieste dall’utente (Agente di Comunicazione Visiva Intelligente);

• Agenti intelligenti per l’estrazione automatica dei dati, metodi di intelligenza artificiale e studi relativi al web semantico (Extractor Plus);

• Una nuova funzione di ricerca ontologica basata sui linguaggi RFID e WOL (Query in linguaggio naturale) basata sulla tecnologia IALINA.

• Un ottimizzatore di query che analizzi le query più frequenti, le classifichi e le esegua automaticamente a scadenze predefinite;
