Design And Research Of A Network Info Radar System

With the development of Internet, information search has become the commonly used means to obtain useful information. Traditional search engines are not appropriate for special disciplines because they focus on the collection and search of all contents available on the Internet. In this thesis we analyzed traditional search engines and their flaws, and then designed a novel search model (network info radar) that meets the requirements of information search in special disciplines.The proposed network info radar is a complementarily and an extension to traditional search engines. It provides a complete solution for information collection, classification, storage, processing, index and personalized services. The network info radar is composed of modules for information collection and monitoring, information analysis and index, automatic information classification, data organization, information index, information processing and publishing, information mining and service, and user authorization, etc. where these modules interact with each other.Combining with the search technology, this paper firstly analyzes the system structure and core algorithms in detail, then proposes a general method for implementing the key system functions based on Java programming language, and finally presents the future work on the network info radar.
