Sda2011 introducing sem lib project
- 1. Introducing the SemLib Project: Seman6c Web Tools for Digital Libraries Chris6an Morbidoni, Marco Grassi and Michele Nucci DII -‐ Department of Informa6on Engeneering Università Politecnica delle Marche, Ancona, ITALY
- 2. Outlines 1. DL Evolu6on 2. Semlib Project 3. Semlib Annota6on System – Use cases – System Requirements – Annota6on Model – Sharing Model – System Architecture – Technical Implementa6on 4. Demo 5. Conclusions 29/09/2011 SDA2011 Introducing SemLib Project m.grassi@univpm.it

DL Evolu6on Experts Create Contents Add Content Add Annotations Digital Library Experts Consume Commenting Contents Tagging Linking Consume Contents Create Contents Digital Library Users Crowdsourcing Consume Commenting Contents Experts Tagging Linking Consume Contents • Users engagement is employed Create Contents Users in achieving a common goal • Enrich and create contents: Social Engagement Digital Library § curate documents Engagement Consume Contents § transcribe manuscripts • Tags, links, comments • Great poten6al Users • I m p r o v e r e s o u r c e r a n k i n g , § Ex. Wikipedia vs MS Encarta classifica6on Expert Model • Users annotate contents for their • Experts create contents and own purposes users consume them Properly structured and machine-‐processable annota6ons: Time -‐ enhance search and browsing capabili6es -‐ provide users a more engaging experience -‐ improve DLs metadata, enrich contents 29/09/2011 SDA2011 Introducing SemLib Project m.grassi@univpm.it
- 4. Seman6c Web Tools For DLs h"p://www.semlibproject.eu/ • R&D project supported by EU FP7 Theme: Research for SMEs (no. FP7-‐SME-‐2010-‐01-‐262301-‐SEMLIB) • 24 months • commenced in January 2011. 29/09/2011 SDA2011 Introducing SemLib Project m.grassi@univpm.it
- 5. SemLib Expected Outputs Seman6c Seman6c Recommender System Annota6on System use Linked Data to improve searching exploit user-‐generated RDF metadata and browsing in the DLs and publish it as Linked Data. 29/09/2011 SDA2011 Introducing SemLib Project m.grassi@univpm.it
- 6. Use cases 1/2 SMEs’ use-‐cases: • Different types of users – Different technical exper6ses – Different roles (DL employers or end-‐users) • Fragments Annota6on – Text fragments / Image regions / Video segments and regions • Seman6c Tags – Unambiguous / Hierarchical Vocabularies – Support user in tag crea6on (ex. sugges6ng tags) – Exploi6ng Similari6es Among Digital Objects 29/09/2011 SDA2011 Introducing SemLib Project m.grassi@univpm.it
- 7. Use Case 2/2 • Seman6c Rela6ons – express more seman6cs specifying the type of rela6on (cite, define, etc.) – answer more precise queries (“show me all sentences that cites a given author) • Annota6on Bookmarking and Sharing – organize annota6ons in different collec6ons – share with other users or user communi6es – Support collabora6ve annota6on crea6on • Annota6ons as enrichment of DLs 29/09/2011 SDA2011 Introducing SemLib Project m.grassi@univpm.it
- 8. System Requirements 1/2 • Modularity of the system – Customizability and Extensibility – Custom configura6ons deliver domain specific annota6on tools to the users (including Javascript libreries or shortcut to bookmarklets) • Seman6cally structured annota6ons • Pluggable vocabularies and ontologies – Flexibility and interoperability – Different applica6on domains • Annota6on at different level of granularity – Whole resource – Resource Fragments (Xpointer, Media Fragment URI) 29/09/2011 SDA2011 Introducing SemLib Project m.grassi@univpm.it
- 9. System Requirements 2/2 • Annota6on at different level of complexity – Text Comments / Seman6c Tagging / Full Statement (S-‐P-‐P) – Automa6c named en66es extrac6on(ex. DBpedia Spotlight) • Organize annota6ons in Notebook • Social Model for Annota6on Sharing • Support for crowdsourced annota6on collec6ons – Annota6on selec6on and cura6on • Highly Dynamic and Interac6ve / Easy to use GUIs 29/09/2011 SDA2011 Introducing SemLib Project m.grassi@univpm.it
