1. 1 ICS-FORTH Dimitris Plexousakis, Pisa, February 2001 WP1: User Requirements Collection and Analysis Dimitris Plexousakis dp@csi.forth.gr Computer Science Department, University of Crete & Institute for Computer Science - FORTH Heraklion, Crete

2. 2 ICS-FORTH Dimitris Plexousakis, Pisa, February 2001 Requirements Elicitation Identify relevant user communities (have we established contacts?) DELOS NoE in Digital Libraries ERCIM Library Representatives German and Italian Societies of Mathematics German Society of Physics Greek Society of Mathematics Hellenic Informatics Society O.A.I user groups Other Networks (e.g., PLANET, OntoWeb)

3. 3 ICS-FORTH Dimitris Plexousakis, Pisa, February 2001 Requirements Elicitation specify scenarios of use assemble and distribute customized questionnaires questionnaires should be detailed but non-technical assumptions about users: familiarity with computer / web-browser use address current practices in literature search tools to use distribution over WWW, e-mail collection through WWW avoid in-print questionnaires web-site hosting questionnaire forms language? (single -- English, multi?)

4. 4 ICS-FORTH Dimitris Plexousakis, Pisa, February 2001 Requirements Analysis Many requirement analysis methodologies exist None is obviously better than the other Goal-based requirements analysis questionnaire processing should lead to goal specification goal decomposition and refinement exception handling though scenario analysis result in operationalizable specifications tools to use (under investigation) some requirements modeling tools exist few analysis tools (e.g., GBRAT) Must capture functional and non-functional requirements
