Thank you Thilo for your helpful and thorough comments on Lucene and UIMA (thread "UIMA and Lucene"). They have helped confirm much of what I suspected and clarified a number of points.
After further discussions with the engineering company they have indicated that semantic search may be better suited to their needs (this is an R&D project conducted between my university and the company, hence why we keep changing out minds :-). With this in mind we are looking at the following products. Any comments on their suitability for integration with UIMA to produce a semantic search solution would be welcome, as would suggestions of other semantic search tools. - Sesame, for storing the CASes produced by our UIMA implementation - Gnowsis, for searching the knowledge base in Sesame or some other RDF database (although perhaps I'm showing my ignorance and it only works with Sesame? :-) Thanks, James.
