1 Ingo Frommholz COLLATE – Collaboratory for Annotation, Indexing and Retrieval of Digitized Historical Archive Material DELOS International Cooperation Workshop, May 30, 2003 Ingo Frommholz Fraunhofer IPSI, Darmstadt

2 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, 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

3 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, The COLLATE Project (IST ) 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

4 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Partners Content providers / pilot users Deutsches Filminstitut – DIF, Frankfurt, Germany Filmarchiv Austria, Vienna, Austria Národní Filmový Archiv, Prague, Czechia Technology developers Fraunhofer IPSI, Darmstadt, Germany University of Bari, LACAM Lab, Bari, Italy Sword ICT S.r.l., Bari, Italy Evaluation partner Risø National Laboratory, Systems Analysis Dept, Denmark

5 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, 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

6 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Censorship / Registration Cards

7 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Newspaper Articles

10 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, System Architecture (OAIS)

11 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Collaboration in COLLATE cataloguing annotation interlinkingindexing terminology development internal (COLLATE system)external traditional - meetings - phone - mail - computer- supported/ online discussion forum implicitexplicit specified relation types communication (e.g. requests) about:

12 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, 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 Annotation 1 Annotation 3 Annotation 4 Annotation 2 Annotation 5

13 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Communication Acts: Discourse Structure Relations interpersonal elaboration background information argumentation comparison cause interpretation analogy difference support argument counterargument

14 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Semantic Web Integration – COLLATE RDF(S)

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

16 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, 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.

17 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Query: censorship decisions for political reasons: Metadata Only I think the reasons mentioned here are not the real reasons. I see a political background as the main reason. 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.... Kuhle Wampe... Oberregierungsrat Dr Becker Beisitzer: Justizrat Dr. Rosenthal obscene actions... Cataloguing Inter- pretation Counterargument Keyword Document Interpretation 0.01

18 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Query: censorship decisions for political reasons: Metadata + Interpretation I think the reasons mentioned here are not the real reasons. I see a political background as the main reason. 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.... Kuhle Wampe... Oberregierungsrat Dr Becker Beisitzer: Justizrat Dr. Rosenthal obscene actions... Cataloguing Inter- pretation Counterargument Keyword Document Interpretation 0.32

19 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, Query: censorship decisions for political reasons: Analysis of Discourse Structure Relations I think the reasons mentioned here are not the real reasons. I see a political background as the main reason. 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.... Kuhle Wampe...

20 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, COLLATE – User Interface

21 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, 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

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

23 Ingo Frommholz DELOS International Cooperation Workshop Prague, May 30, More information?
