| Abstract: | On the basis of analyzing related works, JITIRA, a just-in-time information retrieval agent is designed. The agent processes the queries which submitted to search engines or the newly opened webpage by users. Then, the agent forms automatically a new query immediately, and submits it to search engines. The experiment demonstrates that the above method is helpful to improve the retrieval precision of search engines. |
