Mine biological literatures via a very sophisticated system that goes far beyond what a simple keyword search engine can do.
Highlights:
This search engine enables the user to search for one or a combination of concepts and objects, and/or keywords within a sentence or document, and as the ontology allows word meaning to be queried, it is possible to formulate semantic queries.
Textpresso currently focuses on Caenorhabditis elegans literature, with 3,800 full text articles and 16,000 abstracts.
