Public Opinion Of Oil Field Network Monitoring System Based On Query Expansion

Accelerating expansion of the Internet as an ideological position is, with its relatively unique hidden, freedom, and the rapid spread and other characteristics, more and more channels through which people are willing to express their own personal ideas, and everyone believes in the network issued own view is completely free to publish more content to ignore the health of their sexual and enthusiasm. Regulatory authorities for the network, the Internet greatly facilitate the flow of information in the same time, if not managed and monitored, and its negative effects is very large. In order to protect the network order, and maintain the network and network security of civilization, the Internet supervision is very necessary.Transportation for the state oil enterprise important strategic resource, the mainstay of the country's economic take-off, however, the virtual nature of the Internet makes surfing the true identity of the staff do not have to publish and republish the information can be carried out, resulting in damage to oil fields and even those who do not favor corporate image, reputation for wanton dissemination of information, and even interfere with the normal operation of the oilfield business, corporate social image of the field brought serious adverse effects.In response to these sudden and adverse impact of very bad information on the event, the existing monitoring of public opinion based information retrieval system of recall and precision rate is not ideal, especially in specific areas of application, such as oil fields. To address these issues, in particular to solve the problem of oil field monitoring information, sensitive information will be oil fields as accurately as possible the full control of the extraction of a public opinion research is an important technology. The existing information retrieval technology based on how to effectively determine whether the information more comprehensive information on this technology for the oil field difficulties.In this paper, as follows:(1) Describes the research background, including information retrieval, concept, origin and current situation and problems of information retrieval in the monitoring of public opinion, public opinion outlined the relationship between monitoring and information retrieval and related theories.(2) For the current method of query expansion has been in the oilfield monitoring applications of public opinion on the shortcomings of traditional information retrieval systems to improve query expansion algorithm, cluster based on similar terms and synonyms for query expansion method. The method is able to fully reflect the characteristics of the user area of the thesaurus into the user-defined group of similar terms, the final expansion of the word makes the weight more reasonable, but also improve the recall and precision, the results of query expansion in order to ensure more tends to the user's real thoughts.(3) The combination of extended thesaurus and vector space model to improve the existing text similarity algorithm. Words make the text similar to the calculation of the weight closer to the truth, which impact the exact text similarity.(4) Oil Field was designed and implemented network monitoring system of public opinion, the reasonable application of this research to practice, to bring oil to help control public opinion.
