Iana Atanassova Research: – Information retrieval in scientific publications exploiting semantic annotations and linguistic knowledge bases – Ranking algorithms – Similarity measures using semantic annotation categories (semantic maps) – User interfaces

Challenges – Information retrieval in scientific publications : The notion of relevance in relation to semantic categories present in texts, i.e. “hypothesis”, “definition”, “citation”, etc. – Automatic semantic annotation of scientific texts: hedging, speculations, definitions, etc. – Scientific article invariants related to the use of semantic categories by authors – Large-scale processing of corpora – technical solutions for XML and PDF processing
