Development of ChemAnalyser - a novel, large scale patent search engine
Together with infoapps GmbH in Munich, Germany, OntoChem has developed a chemistry search engine for patent full text documents. Thus, about 90 million patent documents are annotated using OntoChem's UIMA based annotators, ranging from chemistry up to material sciences, from diseases up to cosmetic and nutraceutical terms. In the backend, we are using JChem Base and in the front-end Marvin JS. We will compare the recall and precision of this new search engine with SciFinder, describing the advantages of using ontology based "cognitive search" and searching knowledge N-tuples in non relational databases.
