2012 Summer School September, ENEA, Rome, ITALY Usability Usability is a term used to denote the ease with which people can employ a particular tool or other human-made object in order to achieve a particular goal. “In human-computer interaction and computer science, usability usually refers to the elegance and clarity with which the interaction with a computer program or a web site is designed” (Wikipedia). The document ISO (1998) Guidance on Usability, also issued by the International Organization for Standardization, defines usability as: “The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.”

2012 Summer School September, ENEA, Rome, ITALY 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 Euro every year with looses of 1750 working hours>>.

End-user testing with active assistance. Usability

2012 Summer School September, ENEA, Rome, ITALY End user testing without staff It allows to execute a test without operator presence. The end-user can autonomously complete the tasks predefined by the usability expert. This usability evaluation method is “task driven” and it schedules precise actions inside the LCMS, and they are finalized to the fulfillment by a task oriented end-user and not through a generic navigation. The predefined tasks are highly structured and they guide the end-user to the final result. In this case, the system is able to record a file video containing actions and index referred to quantitative parameters, for example: Mouse click; Keystrokes; Keystrokes; Pages visited and predefined navigation; Pages visited and predefined navigation; Form compilation and query execution; Form compilation and query execution; Errors; Auto Help dialogue windows; Auto Help dialogue windows; User Suggestions form compilation; User Suggestions form compilation; Partial and total execution tasks times.

2012 Summer School September, ENEA, Rome, ITALY End user testing with staff This test consists of end-user behaviour observation to evaluate the experience and the operative context in relation to the e-Learning application functionalities to be tested. The scheduled tasks are not structured. The end- user explores the contents freely while being assisted and observed directly by an operator without any external influence. In particular an empirical technique named "Thinking aloud” has been used. This technique helps the experts to understand the user's behaviour during the navigation in e-learning contents, their selected routes to hit the mark, their expectations and reactions. The testing data model is based on: Errors; Errors; Helps; Helps; End-user Suggestions and comments; End-user Suggestions and comments; Partial and total execution tasks times.

2012 Summer School September, ENEA, Rome, ITALY 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.

2012 Summer School September, ENEA, Rome, ITALY 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 pi ù 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.

2012 Summer School September, ENEA, Rome, ITALY 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 provveder à 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.

2012 Summer School September, ENEA, Rome, ITALY 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 funzionalità del MM; I test di usabilità svolti hanno consentito di valutare positivamente le funzionalità del MM; La valutazione dell’interfaccia, da parte dello staff, è sintetizzabile in una conferma di questa scelta progettuale.

2012 Summer School September, ENEA, Rome, ITALY Conclusioni Le funzionalità implementate nel MM sono basate su quanto definito nella fase di analisi, esse sono:  Presentazione dei risultati in modo omogeneo e standard;  Salvataggio dei risultati della ricerca e dei parametri dell’interrogazione per creazione di query personali;  Visualizzazione dei risultati con differenti ordinamenti;  Stampa dei risultati della ricerca;  Indicazione e visualizzazione del numero totale delle normative;  Associazione dei testi alle normative in formato HTML, DOC, PDF;  Visualizzazione della card (normativa della BDN Agrologis);  Gestione e controllo delle informazioni già presenti, recuperate in precedenti fasi di ricerca, nel database centrale del MM;  Gestione del grado di riconoscibilità delle normative, in termini percentuali, con layout di pagina e contenuti simili in base all’attinenza dell’interrogazione (fase di set-up del MM da parte dello staff);  Conservazione dei dati delle query personali (dossier normativa utente), opzionale.

2012 Summer School September, ENEA, Rome, ITALY Futuri sviluppi In considerazione della complessità del sistema implementato si evidenzia quanto segue circa i futuri sviluppi del MM: Una procedura di estrazione dati che consenta la creazione di estratti elaborati dal sistema basati su ontologie e sintassi specifiche del dominio dati; 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; Un modulo agente software che profili l’utenza in funzione delle interrogazioni e delle informazioni di loro intesse al fine proporre informazioni utili e correlate in primo piano (Focus).
