GenXref VI: automatic generation of links between two heterogeneous databases

Motivation: A large proportion of the information found in public databases is not sufficiently cross-referenced. We developed genXref, an automated system for link inference, because embarking on a manual cross-referencing of genome data would require too much expensive human expertise. It uses information retrieval technology to generate links between objects of heterogeneous databases. Results: GenXref was used ro generate links between GDB ger zes and Genbank human sequences. if resulted in >10 000 links with a precision of 83% ana a recall of similar to 32%. Availability: The links generated by genXrefare stored in the Virgil database: http://www.infobiogen.fr/services/virgil/home.html Contact: Frederic.Achard@infobiogen.fr.
