Thanks for your answer. Indeed I need to read the UIMA documentation better. We are building a system that will support Busines Intelligence applications based on a data warehouse, as well as knowledge management features based on a knowledge base. We are looking at UIMA for the loading into the knowledge base. We have multiple data sources, some are completly structured. Others are semi-structured (well defined fields, but main input is free text fields). And other again are completly unstructured (presentations, concept papers, etc). The data warehouse we will use for report generation, trending and data mining. On the knowledge base we would like to perform simple keyword search and indeed Lucene is a candidate (Solr is a better candidate as it among others support substitution) but we would also like to perform based reasoning, as well as ontology based reasoning / derivation of knowledge. And we are therefore looking at a knowledge base containing a RDF data graph, not just a flat index. As far as I have been able to gather from the internet there has been some of discussion on integrating Apache UIMA and Lucene, but no integration has actually been made. A better way of asking the question is therefore; for our knowledge base, what do we use to create the RDF data graph? Should we: 1. Split this into two separate tool chains, one for structured data and one for unstructured data (based on UIMA)? 2. Use UIMA for structured as well as unstructured? Gert.

Your description is a little vague. Perhaps you could provide some use-cases? I recommend that you read the UIMA docs and then ask any questions you still have. Be aware the UIMA is not a search engine. If all you want to do is index some documents, then maybe all you need is Apache Lucene. For the structured side, maybe you need a data warehouse. Or maybe you just want to index some of the CLOBs and VARCHARS into a search engine. It's hard to tell from your description.
