| Outline of Final Research Achievements |
The current Web search engines have a very high retrieval performance as long as the proper retrieval terms are given. However, many people, particularly children, seniors, and foreigners, have difficulty deciding on the proper retrieval terms for representing the retrieval objects, especially with searches related to technical fields. In this study, we developed a support system that can highly accurately predict suitable retrieval term candidates when some clues such as their descriptive texts or relevant/surrounding words are given by the users, adopting deep learning methods and the latest information retrieval technology.
