  1. Semantic Technology Application Show Cases Atilla ELÇİ Dept. of Computer Engineering Eastern Mediterranean University CmpE 588 Spring 2008 EMU

  2. SemTech Applications • Show case application of SemTech to Digital Library • SemTech’s role in meeting challenges • Davies et al. Ch. 11. • PS: Takehome MT: Review & Qs. CmpE 588 Spring 2008 EMU

  3. Current Digital Libraries • Samples: • ACM Member DL • Free libs: • Project Gutenberg: e-books of all genres. • Open Library by the Internet Archive: to showcase how and provide free. • Wikipedia • You Tube? Etc. • Free digital library software: • Greenstone DL with UNESCO’s support • OpenDLib • Search engine as DL: Google Scholar • Wiki as DL: Wikibooks: Wikimedia Project free textbook project. CmpE 588 Spring 2008 EMU

  4. Free Digital Libraries Directory? • Let’s put together a list of digital libraries offering free e-material. • Organize the list using semantic technology. • Build i/f for human reader and software agents. CmpE 588 Spring 2008 EMU

  5. DL Challenges • Key research areas by Digital Libraries Workshop (1995): • Interoperability: • Software and systems • Semantic: mapping ontologies • Description of objects and repositories • Collection and management of non-textual information • User interfaces • Economic, social and legal issues. • SemTech contribution to above: Where and How? • Newer research findings? CmpE 588 Spring 2008 EMU

  6. DL Research • Specific purpose projects: • Alexandria Digital Earth Project: geospatial data • PERSIVAL: medical data • VARIATIONS: music • EULER: math. • Generic research projects: • Perseus DL Project: humanities source material. • Renardus Service of 5th FP IST Project: integrated search & browse access to records through gateway services. • Scuplteur: semantic & content-based multimedia mngt: • There is an ontology to describe the objects • Crawler searches web for more • 6th FP DELOS: “the next generation of DL technologies” • 6th FP BRICKS: upto “open, user- and service-oriented infrastructure for sharing knowledge & resources”. CmpE 588 Spring 2008 EMU

  7. DELOS • Aimed for th ‘Next generation of DL tech.’ • Architecture has seven clusters: • Knowledge extraction and semantic interoperability • Info access and personalization • User interface and personalization • ... CmpE 588 Spring 2008 EMU

  8. A Case Study: The BT DL (Sect. 11.3) • Enhancing the Library w/SemTech (SEKT Project): • Richer Metadata: • ABI/INFORM from ProQuest: 8 K terms vocabulary • IEEE INSPEC: 9 K terms • Enhanced User Profiling: • Personalization • In-fulltext search and annotation • Enhancing: searching, browsing, displaying results, connecting people/ideas CmpE 588 Spring 2008 EMU

  9. The User’s View • Sect. 11.4 CmpE 588 Spring 2008 EMU

  10. SemTech to DL’s Rescue: (Sect. 11.5) • BT DL Run-Time Architecture: • 5-Layer Architecture: • Persistence Layer • Semantic Layer: • PROTo Ontology Proton • Dublin Core • OWL • Integration Layer: • Building appls using components of SEKT Integration Platform (SIP) • End-User Appls Layer: • Appls built using SIP, such as the following • Semantic search & browse • Knowledge sharing • Personal search agent • Semantic info spaces (search-based carry over from original BT DL) • Presentation Layer CmpE 588 Spring 2008 EMU

  11. SemTech to DL’s Rescue: (Sect. 11.5) CmpE 588 Spring 2008 EMU

  12. SemTech-Based DL: Future Trends • Open source • Open content • Publically collaborated development and upkeep • Rich metadata • Ontology-based • Personalized • Distributed, localized • Push or pull? • Imploys SemTech tools: • Ontology evolution, • Content gathering • Search • Presentation • ... • Your call?
