Internet Data-based Topic Detection And Tracking Technology Research And Implementation

With the rapid development of the Internet, great changes have taken place in people's work and way of life. Information and communication posted on the Internet, people can obtain more information, and everyone can be the publisher and disseminator. Various forms of information carrier of information filled with the Internet, good, bad, true, false, make it difficult to identify, so the supervision and management of Internet data becomes more important. However, the study of the Internet, found a hot topic, and track the spread and development topics, has received increasing attention and concerns all aspects.Internet is a huge unstructured database, libraries of data types and data formats are different from each other, to get the data from the Internet was a more difficult, to found immediate topic in such a huge amount of information, and learn about topics of the propagation process, track topics are reality even more difficult.In this paper, data acquisition and topic detection technology, comprehensive domestic and foreign scholars in research results, based on the practical application of operational staff through to the problems encountered in the process of analysis, research and designed Internet-based data, data collection, topic generation and topic tracking, and enable analysts to participate in the process of operation of the system to improve the accuracy of data collection, topic detection efficiency, accuracy and tracking topic. A better understanding of the relevant departments for the Internet, the emergence of new topics and topics of the communication process has played a supporting role.This article is divided into six chapters:Chapter One of the background, literature review and thesis Introduction; second chapter topic detection and tracking of Internet technology-based presentation; third chapter introduces the topic of Internet-based data discovery technology, key technology research and implementation. Chapter IV on the topic of Internet-based data tracking technology has been studied and elaborated realization. Chapter V:The above data raised the topic of Internet-based detection and tracking some of the implementation method into the case study. Finally, conclusions and outlook.This paper presents data based on Internet search engines and Web sites within the search results achieved the template for the realization of the data, search engine API access to data, and sorted according to relevance filtering of data, given the spread of the path diagram.Research topics and contents of this article from the 2009 National Natural Science Foundation research project training topics (No.90924013) "non-conventional emergency cognitive model of network information, communication and early warning mechanism of the law."...
