1. Introduction
</SectionTitle>
    <Paragraph position="0"> Internet is changing the world, and at the same time changing people' s information seeking behaviour. Traditionally, information searchers are trained professionals working in libraries or other special technical or scientific fields. They have developed a variety of techniques and heuristics for addressing information seeking difficulties in the environment typically dominated by Boolean query formula. These Boolean information retrieval systems are normally commercial and non-interactive systems and the searches conducted in such settings are exact-match and set-based retrieval from databases of indexed citations and abstracts of documents (Koenemann and Belkin, 1996). With the dramatic explosion of information sources over Internet, current user population is no longer restricted to' professional searchers. Practically it includes everyone in life. The majority of these users, however, are either casual or novice or both. Casual users, such as browsers of news stories, look for interesting information rather than information relevant to a specific need (Stadnyk and Kass, 1992). Novice users may have a specific information topic, but due to little or no training in search and retrieval, they don' t know how to make best use of the available operators and tools. On the whole, query formulation is one problem facing both types of information users (Turtle, 1994). Internet users all have difficulty in mapping their intent to any logical query structure. They prefer limiting their searches to one or a simple list of terms, while seeking help from the system to guide them to achieve their ultimate information goal.</Paragraph>
    <Paragraph position="1"> In this paper we introduce an integrated system that combines a standard search system with a query reformulation model, a pre-constructed concept network, an automatic document summarizer, and an optional text-to-speech (TTS) engine. Together, these intelligent components provide intuitive human intelligence to the Chinese users over Internet.</Paragraph>
    <Paragraph position="2"> The integrated system not only guides and navigates the user to perform searches in a humanly conversational way, but also makes and delivers the retrieved information back to the user in a simple, succinct, and easily comprehensible manner.</Paragraph>
