PIES, a protein interaction extraction system.
We consider the problem of extracting, manipulating, and managing biological pathways, especially protein-protein interaction pathways. We discuss here the Protein Interaction Extraction System (PIES). PIES is contructed on top of three main technologies: Kleisli, BioNLP, and Graphviz. Kleisli is a broad-scale data integration system that we use for downloading Medline abstracts and for general manipulation and management of pathway/interaction databases. BioNLP is a natural language-based information extraction module that we use for analysing Medline abstracts and to extract precise protein-protein and other interaction information. Graphviz is a graphical layout package developed for directed graphs that we use for visualization of the extracted pathways. PIES can be augmented with various means for extracting protein interaction information from sequence databases, for example, by using Kleisli's power to integrate sequence comparison tools to detect gene fusion events in sequence databases.
