Collaborative Information Retrieval Framework Based on FCA

In Collaborative Information Retrieval, we construct formal concept lattices for a number of sub-text databases by the incremental update algorithms for generating the lattices algorithm. Then, respectively, we obtained the new formal concepts by merging the temporary formal concepts which are from the different lattices by measuring similarity between formal concepts and next, matching the new concepts to return the results which are to meet the user needs ultimately. The whole framework is easy to deploy in a distributed environment and match the query words in an imprecise way. It reflects the needs of humanity better.
