Extracting Molecular Binding Relationships From Biomedical Text


ARBITER is a Prolog program that extracts assertions about macromolecular binding relationships from biomedical text. We describe the domain knowledge and the under-specified linguistic analyses that support the identification of these predications. After discussing a formal evaluation of ARBITER, we report on its application to 491,000 MEDLINE abstracts, during which almost 25,000 binding relationships suitable for entry into a database of macro-molecular function were extracted.
