Abstract

The invention belongs to the technical field of computers, and provides a network information semantic orientation analysis method and system. The method comprises the steps that a name of an enterprise is obtained; information related with the enterprises is searched on the internet by using a web crawler, and the information is stored in a database in the form of a text; the text is decomposed into logical word sequences by using a tokenizer, and the word sequences are stored in a word decomposition base; the word sequences are taken out from the word decomposition base and inputted into a corpus analyzer, and the word sequences with part-of-speech tagging are obtained; the word sequences with part-of-speech tagging are inputted into an emotion tendency classifier, the emotion tendency values of the text are obtained, and accordingly the emotion tendency of the text is obtained. According to the method and system, mass information of the internet is used as an information source, the positive and negative tendency of the enterprise information is rapidly calculated and judged, so that public users can rapidly and comprehensively acquire the business and public opinion information of the enterprise, and the device can also provide information retrieval technical service for industries, institutions and enterprise users.
