Automated extraction of structure-activity relationships from chemistry patents

At the Amercian Chemical Society meeting ("Hunting for hidden treasures: chemical information in patents and other documents") in Philadelphia, OntoChem presented the automated SAR extraction from patents. First, chemical information, including structures, compound classes, and biological effects, is extracted from patent text. Second, relationships about the compounds and effects are analyzed for their syntax. Last, the normalized relationship n-tuples are generated, and a structure activity relationship can be derived to fuel search engines.
