1/471/47 Serbia-Forum Cultural Heritage Digitization Project with Emphasis on Semantic Indexing Aleksandar Mihajlovi Vladisav Jelisavi Bojan Marinkovi Zoran Ognjanovi Veljko Milutinovi Zoran Markovi Mathematical Institute of the Serbian Academy of Arts and Sciences Knez Mihailova 36, 11000 Belgrade, Serbia

2/472/47 What is Serbia-Forum?

4/474/47 Motivation for Digitization Why is Preservation a top priority?

5/475/47 What is Serbia-Forum? Axioms holding Serbia-Forum together Primary axioms (fixed to the serbia-forum project): Content is selected and controlled by government funded and owned cultural and academic institutions Each document is copy protected by a different license Quality NOT quantity Secondary axioms (implementable by other projects): Semantic search Version tracking of every document Information about the author of each document is supplied (biography)

6/476/47 What already exists Wikipedia Europeana Austria-Forum... Europaea-Forum Why Serbia-Forum?

7/477/47 Wikipedia

8/478/47 One product of Wikimedia

9/479/47 Wikipedia A broad collection of written knowledge in the form of articles (knowledge concerning the whole world)

10/47 Wikipedia A broad collection of written knowledge in the form of articles (knowledge concerning the whole world) Free encyclopedia Distributed organization Product localized by lingual regions Wikipedia Serbia, Wikipedia Poland, Wikipedia Italy itd

11/47 Wikipedia

12/47 Wikipedia Wikipedia is based on free authorship merits of the CC license (Creative Commons license) Every article written for wikipedia may be used, printed, sold and changed freely without breaking the law. One of the main factors for the success and expansion of Wikipedia Every user can write an article about any topic Every article is apt to changes

13/47 Wikipedia Articles are available in many languages Wikipedia in English contains about 3 500 000 articles, Wikipedia Germany about 1 385 000, Wikipedia Spain about 880 000, etc Wikipedia Serbia contains over 156 000 articles in Serbian.

15/47 Wikipedia Even if there exist a significant number of documents in Serbian, a significantly smaller number of articles represent concepts related to Serbian cultural heritage. In the midst of insufficient representation, a need arises for the systematic collection and presentation of concepts, significant historical figures and events in Serbian history and culture. One solution is: http://wwww.serbia-forum.orghttp://wwww.serbia-forum.org

16/47 Wikipedia Strategic constraints of Wikipedia (1/2) Encyclopedia of knowledge concerning the whole world, not only Serbia Serbia and Wikipedia are connected by only one string: The Serbian language Tracking article changes is a hassle There is only one valid license: Creative Commons Which makes thing a bit inflexible The free authorship approach sometimes doesnt yield satisfactory results (credibility) No editorial board to determine credibility of author and article Articles can contain stereotypes, false truths and biased information

17/47 Wikipedia Strategic constraint of Wikipedia (2/2) Contains only encyclopedic articles; Weak assortment of books Weak assortment of documents No archive contents Wikimedia Commons? Wikisource? Wikibooks? Repeat: Only one valid license: Creative Commons Out of context

18/47 Europeana Collection of information concerning European cultural heritage Access to millions of books, pictures, museum pieces, movies and archive data Its not an encyclopedia Under the supervision of the Europeana foundation Over 2000 institutions all over Europe Every institution individually is responsible for the selection and presentation of its contents Contribution is exclusively reserved for institutions

20/47 Europeana Advantages? Rights are protected Credibility is ensured Content is diverse Disadvantages? It is just a portal Collection of documents vs encyclopedia
