Protein-Protein Interaction text analysis

Protein-Protein Interaction (PPI) is one of the most important fields in biomedical research due to its enormous interest in genetics, medicine and pharmacology. Therefore, (semi)-automatic analysis of biomedical texts is critical for recovering and maintaining experimental descriptions which justify the presence or absence of such interactions. In this paper, an automatic, on-line system is described which, given a text, verifies if it corresponds to a PPI article, and recognizes various types of entities associated to this research context.
