Ppies: Protein-Protein Interaction Information Extraction System

More than three millions research articles have been written about proteins and Protein-Protein Interactions (PPI). The present work describes a plausible architecture and some preliminary experiments of our Protein-Protein Interaction Information Extraction system, PPIEs. The promising results obtained suggest that the approach deserves further efforts. Some important aspects that need to be improved in the future have been identified: entity recognition; lexical data storage and searching (in particular, controlled vocabularies); knowledge discovery for ontology enrichment.
