3. Recommender Service l Functionality »Users get recommendations about documents in archives that might be relevant »Users get information about other users and communities of potential interest »User can rate documents »Users can view and query rates of documents »Users can send recommendations to other users »Users get recommendations about other users who might also be interested

4. Recommender Service (contd) l Hybrid space »Neighbourhoods = communities of interest »Social space model based on similarity of users rating patterns (analysis of user behaviour) »Content space model based on similarity of users content-based profiles (analysis of user profiles)

5. Recommender Service Components l Community building component »Compares interests among single users and between single users and communities »Provides information about matches l Rating component »Provides interface for rating documents »Provides interface for reading and querying ratings »Administrates ratings and controls access l Recommender component »Generates and presents recommendations according to the users behaviour and interest profile »Administrates user preferences as to the contents and the schedule of recommendations

6. Collaborative Work Service l Functionality »Users can annotate and rate documents »Users can share documents and meta-data in a community of interestthat is, add/remove documents and meta-data, grant/revoke access, etc. »Users are notified about changes in shared documents and meta-data »Users can specify preferences for notification (e.g., which documents, schedule) »Users are made aware of other users who are online at the same time and can have spontaneous conversations »Users can develop a community-specific terminology »Users get automatic cross-references for content-based navigation

7. Collaborative Work ServiceComponents l Sharing component »Administrates community documents and controls access »Provides functionality for adding, deleting, versioning community documents l Communication component »Provides chat tool l Awareness component »Captures, administrates, and presents information about documents and activities in the communities
