Information retrieval based on temporal attributes in WWW archives

Today, WWW is a media needed for us. Therefore, WWW should be archived and it should be also allowed to retrieve anytime. In such a digital archive, temporal information retrieval is very important. Temporal information retrieval is a kind of information retrieval based on temporal attributes of a document. In order to realize temporal information retrieval, we need the huge storage in which all of documents from past to future are stored. This is very difficult for a conventional centralized system. But, it is possible for a distributed system. In this paper, we propose temporal information retrieval based on distributed search engine.
