2. ELPUB 2007 Vienna, Austria - June 2007 Towards an ontology to ElPub/Sci-X: a proposal 2006 (10 years) : the motivation Quantitative aspects  Authors productiveness  Changes in authorship  Papers per country  Works per year Qualitative aspects  Most approached themes  Most approached environment  Recent focus

3. ELPUB 2007 Vienna, Austria - June 2007 Towards an ontology to ElPub/Sci-X: a proposal 2006 (10 years) : the difficulties Quantitative aspects  Authors names  Institutions names  Lack of standard data  affiliation - institution hierarchy?  city x state x country  sessions x tracks Qualitative aspects  Lack of data & of standard data (keywords, abstracts)

4. ELPUB 2007 Vienna, Austria - June 2007 Towards an ontology to ElPub/Sci-X: a proposal Ten years of ElPub: Standardisation of names (authors and institutions) However Not yet aggregated to the collection Moreover The need of standardising keywords (yes!), abstracts (maybe)

5. ELPUB 2007 Vienna, Austria - June 2007 Towards an ontology to ElPub/Sci-X: a proposal  The problem: ElPub/Sci-X database, as a collection of whatever is found in the proceedings One of the solutions: a standard ontology language (ElPub/Sci-X Ontology)

6. ELPUB 2007 Vienna, Austria - June 2007 Towards an ontology to ElPub/Sci-X: a proposal The project aim: To create an ontology that will help the exploration of ElPub/Sci-X content in both quantitative and qualitative ways

7. ELPUB 2007 Vienna, Austria - June 2007 Towards an ontology to ElPub/Sci-X: a proposal The work is comprised of:  File conversion  Natural language processing  Ontology creation and editing

9. ELPUB 2007 Vienna, Austria - June 2007 Towards an ontology to ElPub/Sci-X: a proposal  Visit Sci-X site and collect the entire collection of ElPub papers  Transfer the collection into a native database  Manually extract titles, author’s and institution’s names, as well as keywords  Replace authors and institution names in the native database by the canonical names created by Costa et al (2006)

10. ELPUB 2007 Vienna, Austria - June 2007 Towards an ontology to ElPub/Sci-X: a proposal  Convert all pdf files into txt files  Send the texts (no abstract and references) to a syntactic analyser (Syntactic Parser VISL), which generates a syntactic tree with all syntactic tags  Send the syntactic tree to GeraOnto (Gottschalg- Duque, 2005), which extract the concepts  Insert the concepts into Protegé, which edits the ontology
