Hi Jiang, I'm currently facing a similar problem. Up to now I have to use for the semantic query a graph matching algorithm, but the fulltext search in the semantic web is performed by lucene. At first I wrote the whole text into a one index. The document contains one field for the unique id and on for the whole text. For the semantic markup I use an extra index. Every rdf triple will result in a document with the following fields id, predicate + subject + object. Every query is executed on both indexes. I use an extra index for the rdf data, because this results in a higher score for the documents. You might argue that this would adulterate the result, but from me point of view explicit Meta data should be higher scored then terms in document body.

I am trying using the lucene for searching documents with ontological annotation. But i do not get a better model to combine the keywords information and the ontological information. regards jiang xing --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
