Hi Harish, thanks for your interest. Regarding details on the engine, please refer to the following blog post (it should answer partly your first and second question):
http://blog.iks-project.eu/dbpedia-spotlight-integration-in-apache-stanbol-2/ For a functioning demo of the described engines and chains, please refer to the following Stanbol instance (please note that the engines are rather "generously" configured, so they will return all results currently. Filters based on confidence metrics can of course be applied to improve precision): http://spotlight.dbpedia.org/stanbol/enhancer/chain Let me answer your second and third question too: 2) DBpedia Spotlight is a stand alone tool, which was designed to do a similar task to the current default Stanbol chain. We merely integrated it in Stanbol with this EnhancementEngines. It goes through the whole annotation life cycle (NER, DBpedia resources candidate selection, disambiguation, linking). So it basicly is an alternative to the already existing engines, as we all know - results differ according to a use case. So the more alternatives we have to combine (by that I mean engine), the better optimization possibilities there are. For further info on DBpedia Spotlight, please refer to the project Wiki (https://github.com/dbpedia-spotlight/dbpedia-spotlight/wiki) 3) No, it doesn't. As I mentioned - DBpedia Spotlight is a stand alone tool, and it has it's own indexes. best, Iavor Am 30.07.2012 19:29, schrieb harish suvarna: > Thanks lavor. These will be great of usage. > 1.
