Main research topics in Adachi Lab. are Information Retrieval and Information Linkage.
Information has been explosively increasing, and it is difficult for users to select appropriate information from these huge data. We challenge this problem by using information retrieval and database techniques.
Our researches are as follows:

Information Retrieval
Information retrieval systems are used to satisfy a user’s need for acquiring documents relevant to a query. However, existing search engines may not avoid showing search results including documents irrelevant to users’ query because queries can be ambiguous. We propose methods that reduce disambiguations of queries and search results. In addition, for realizing scalability and load balance, we propose a Peer-to-Peer information retrieval scheme that searches and gathers relevant documents with small network traffic.
