Research On Network Information Extraction Method Based On Knowledge Discovery In The Era Of Big Data

With the development of network application technology and the increasingly sophisticated digital environment, a large number of intelligent information devices are highly connected in series on the network, resulting in a large number of network data. Big data era prophet victor. Schonberg in "the era of big data:great changes in living, working and thinking, " pointed out that "brought about big data information storm is changing our life, work and thinking, big data opened a major transformation of the era". However, with the rapid expansion of the number of information, how to extract a large number of structured, semi-structured and unstructured complex data has become the urgent task of information service institutions. Based on the present situation, the network information extraction method based on knowledge discovery system which serves the information users has become the inevitable choice of the information service institutions in the era of big data.The main contents of this study include:First, related concepts in large data base theory as the basis, for knowledge discovery system of carding and defined, then the data extraction is a comprehensive introduction, to determine the age of big data knowledge discovery system of network information extraction method.Secondly, it analyzes the development of China’s big data, using a variety of methods, including the integration and method of the extraction of some data information under the big data.Finally, in the era of big data development status and conditions of network information extraction analysis method on the basis of big data era below to knowledge discovery of network information extraction method is feasible and the maximum efficiency.
