  2. Project COLLATE Theme:Computational Linguistics and Language Technology for Real World ApplicationsSupport:A Grant by the German Federal Ministry for Education and Research (BMBF) for RTD strengthening the position of Saarbrückenas a Competence Center for Language TechnologyPIs: Hans Uszkoreit, Manfred Pinkal and Wolfgang WahlsterDuration: Spring 2001 - end of 2003

  3. COLLATE Project Structure Coordination, Controlling, Reporting, WWW Presence, PR, Events basic functionalities of LT-based knowledge management Competence Center in Speech and Language Technologze information extraction and fusion dialogue for knowledge access Virtual Information Center Demonstration Center information management and retrieval Evaluation Center

  4. Need for a Competence Center • LT field is growing • Researchers from LT and neighbouring disciplines need a comprehensive information service • Users of LT need in-depth information about technologies, available products and suppliers • Users of LT need support to find or develop solutions meeting their application requirements • Developers and users of LT need criteria and evaluations regarding the usability of LT in real world applications • Students of LT need an information source

  5. 1. Virtual Information Center: LT World

  6. LT World: Idea and Context • The virtual information center is a comprehensive WWW-based information and knowledge service for the entire area of language technology. • LT World is a “virtual” center in the sense that most information will physically remain with their creators or with other service providers. • The virtual information center has been online since October 2001 under the name „LT World“ for „Language Technology World“ (www.lt-world.org)

  7. Virtual Information Center - LT World • Information and Knowledge • Technical and Scientific Information • Players and Teams • Persons, Projects, Organisations • Resources and Results • Research Systems, Commercial Products • Communication and Events • News, Conferences

  8. LT World Ontology Layer 3: Ontology for CL & LT Products Projects People Publi cations Corpora etc. Layer 2: Specific Ontologies Layer 1: Dublin Core

  9. LT World: Coverage • 99 topic nodes • 300 NLP tools and products • 1800 people • 850 organisations • 500 projects

  10. Data Acquisition Process • Manual collection, categorization and annotation of URLs by students and staff • Sources: conference proceedings and journals, lists of links on the web, • Self-registration and correction of data by users of the service • Technical/scientific information in topic nodes has been provided by domain experts

  11. LT World: Topic Nodes Topic nodes are the main information unit of the Area “Knowledge and Information”. They are organized in a shallow slightly multidimensional hierarchy following the chapter plan of the second edition of the Language Technology Survey Example of the shallow hierarchy Information Extraction • Named Entity Recognition • Terminology Extraction • Relation Extraction • Answer Extraction

  12. Information for each Topic • Name • Acronyms • aka‘s, Term Translations • Short Definition • Overview Article (from HLT Survey) • Topic Websites • R&D Prototypes/Products • Projects • People • Literature

  13. Hyperlinking between Sections

  14. Relationship to External Resources • Included but autonomous resources: ACL Software Registry, Language Technology Survey • Systematically cross-Linked and Cross-Searchable Resources: all OLAC Resources such as (LDC, ELRA , SIL, ACL SR, and OLAC Home) • Systematically crosslinked resources: HLT Central, ELSNET, ACL NLP Universe, EACL, COLIBRI • Linked resources: All other relevant resources relevant for LT

  15. Future Work: Virtual Information Center • Update of Information and Knowledge section in cooperation with 2nd edtion of HLT Survey • Interaction (chatrooms, discussion boards) • Job offers • Use of language technologies to improve the content of LT World • Improved hyperlinking between the different sections • Resource discovery • Automatic metadata extraction • Construct corpus of LT area as R&D resource

  16. 2. Demonstration Center

  17. Demonstration Center • Ppotential users and other interested parties can see and test the most important research prototypes and products of language technology • The demo center is available for seminars, tutorials, and information visits • Beneficiaries are: companies and other organizations interested in the deployment of language technology, researchers and developers of language technology, other decision makers with an interest in the state of the art in LT

  18. Demonstration Center: Technical Setup • PC-based demonstration kiosks • Audio-visual network allows redirection of voice and video in/output between kiosks • Specially equipped room for in-depth demonstrations • Demo scripts and data for different kinds of applications

  19. Demonstration Center: Installed Software • Machine Translation (LOGOS, Linguatec Personal Translator ...) • Spoken dialogue system (Sympalog, Nuance, Speechworks...) • Text to speech synthesis (RealSpeak, Mary ...) • Information Extraction (LaSIE, SPPC, ...) • Dictation System (Dragon NR, L&H ASR 16, ...) • Finite State Tools (XEROX XLE ...) • Multimedia Indexing and Search (MUMUS ...) • Spellchecking for professional users (CLT Corrigo ...) • Voice Dialling (VoiceDirector) .....

  20. Future Work: Demonstration Center • New software is acquired and existing software updated • Information days and seminars (starting autumn 2002)

  21. 3. Evaluation Center

  22. Evaluation Center: Idea • Development of methodology for an individual customized evaluation of LT applications • The focus is neither general technology evaluation (TREC, TIPSTER etc.) nor generic product testing according to a fixed set of criteria • The focus of the evaluation center is a thorough, customized and goal specific evaluation of individual applications. The evaluation will center on usability, interoperability, and adequacy with respect to specified tasks.

  23. Evaluation Center: Usability Studies • Evaluation of the overall usability of LT systems for real users in typical contexts • Current focus is on studying the interaction of users with LT applications, making use of a portable eye-tracker • Combination of eye-tracking and user interviews yields new insights into usability design

  24. Initial Version of User Interface

  25. Improved Version of User Interface

  26. Conclusion • Thanks to the funding by BMBF and thanks to existing valuable resources such as the HLT Survey and the ACL Software Registry, we have set up the most comprehensive information resource on Language Technology. • We welcome any comments and proposals for collaboration that could help to strengthen LT World and the entire infostructure of our field. • Demonstration center and evaluation center provide useful services to developers and users of LT.
