  1. COLLATE – Collaboratory for Annotation, Indexing and Retrieval of Digitized Historical Archive MaterialDELOS International Cooperation Workshop, May 30, 2003 Ingo Frommholz Fraunhofer IPSI, Darmstadt frommholz@ipsi.fraunhofer.de http://ipsi.fraunhofer.de/

  2. Digital Libraries in Cultural Heritage • Valuable historic document collections exist, but are scattered in national archives • Sources mostly not available online • Difficult-to-use database & referencing systems • Lack of content-based indexing & access • Valuable expert domain knowledge exists, but mostly inaccessible to externals • Tacit knowledge, insufficiently documented • Professional communities lack technology support for collaborative knowledge working DELOS International Cooperation Workshop Prague, May 30, 2003

  3. The COLLATE Project (IST-1999-20882) • Constructing a “Collaborative Information Space” • Preserve historic documents in a distributed multimedia repository • European historic film documentation (20ies and 30ies) • Historic film censorship (legal docs, applications & decisions, correspondence, etc.), Press material (articles), Photos (stills, portraits) & film posters, Digital film/video fragments • XML metadata (cataloguing & content indexing) • Ensure accessibility • Work environment for content indexing & annotation • Content- and context-based retrieval • Evaluate acceptability • Preservation case studies by film experts • Empirical studies of real-life user behavior DELOS International Cooperation Workshop Prague, May 30, 2003

  5. Why a Cultural Collaboratory? • Support existing work processes in cultural sciences • Interpretative content analysis of documents • Reconstruct „unity“ of cultural phenomena, interlinking scattered knowledge sources • Offer new knowledge working environment • Organize collaborative work • Bring together divergent user communities & roles • Create enhanced cultural information services • Raise awareness & visibility of cultural archives DELOS International Cooperation Workshop Prague, May 30, 2003

Annotation 1 Annotation 2 Annotation 3 Annotation 4 Annotation 5 Discourse Structures • “Discourses represent extended communication between two or more participants in a shared context.” (Rich & Sidner, 1998) • Establishing a discourse context • Modeling discourse as interrelated nested annotations • Annotation thread reflects scientific discourse • Typed links (DSR) between • Document and annotation • Annotation of annotations DELOS International Cooperation Workshop Prague, May 30, 2003

  15. Document Retrieval in COLLATE For a query q, a ranking of documents is returned. Therefore, a retrieval weightris calculated for each document. Documents are ranked according to descending retrieval weights The retrieval is based on the document’s metadata (given by film scientists or extracted from the digitized documents) and on the annotation thread. DELOS International Cooperation Workshop Prague, May 30, 2003

  16. Context-based Retrieval in COLLATE In COLLATE, we deal with the discourse context. A document is seen in the light of its interpretations We also consider at which point of the discourse a statement is made and what relation exists between the statement and the entity this statement refers to. Example: Consider the query for “all censorship decisions made for political reasons”. DELOS International Cooperation Workshop Prague, May 30, 2003

  17. Query: “censorship decisions for political reasons”:Metadata Only ... <controlled_keyword> obscene actions </controlled_keyword> ... I think the reasons mentioned here are not the real reasons. I see a political background as the main reason. 0.01 Keyword Inter- pretation Counterargument Document Interpretation I disagree. There were a lot of similar decisions with the same argumentation. Of course, there might be a political background, but I think this is not the main reason in this case. Cataloguing ... <assessors_chairman> Oberregierungsrat Dr Becker Beisitzer: Justizrat Dr. Rosenthal... </assessors_chairman> ... ... <filmtitle> Kuhle Wampe </filmtitle> ... DELOS International Cooperation Workshop Prague, May 30, 2003

  18. Query: “censorship decisions for political reasons”:Metadata + Interpretation ... <controlled_keyword> obscene actions </controlled_keyword> ... I think the reasons mentioned here are not the real reasons. I see a political background as the main reason. 0.32 Keyword Inter- pretation Counterargument Document Interpretation I disagree. There were a lot of similar decisions with the same argumentation. Of course, there might be a political background, but I think this is not the main reason in this case.

  20. COLLATE – User Interface DELOS International Cooperation Workshop Prague, May 30, 2003

  21. Current State A first prototype was delivered to the archives and is used by them A second prototype will be delivered soon, introducing discourse structure relations and advanced collaboration features to the users A third prototype will contain context-based retrieval DELOS International Cooperation Workshop Prague, May 30, 2003

  22. Outlook Evaluate collaborative approach and context-based retrieval Apply COLLATE technology in other domains? DELOS International Cooperation Workshop Prague, May 30, 2003
