Frequently Asked Questions technique (FAQ) is technique commonly used today to answer large number of user queries which are in natural language form and where many of them should result with same answer. In this work I utilized the fact that those queries can be grouped (clustered) by their answers in order to achieve better performance in terms of precision and recall when searching for answers during new query. While moving through user interface users actually give feedback to clustering algorithm making it semi-automatic. At the end I compared performance of system in different modes: read-only mode (classical searchable FAQ), non-clustering mode (answer is added to each question if similar is already answered, no grouping), clustering mode.
Results showed that system based on proposed clustering and implicit users evaluation, can, if answer already exist, answer to 84% of users questions by giving them 4 results and can, again, if answer already exist, answer to 30% of questions by giving them single correct answer.
