Abstract

The invention discloses a text field determination method and a system for a field semantic relation graph. The method comprises the steps of processing a to-be-analyzed text to obtain a statement setand a text vocabulary set; determining a text vocabulary score of each vocabulary in the text vocabulary set in a domain semantic relation graph, wherein the domain semantic relation graph is generated according to a text collected from a network platform; determining a vocabulary joint score according to the statement set and the domain semantic relation graph; determining a domain total score according to the vocabulary joint score and the text vocabulary score; and determining a text field to which the to-be-analyzed text belongs according to the field total score. According to the field semantic relation graph generated by the text collected from the network platform, the text can be analyzed for the special domain as required by determining the text vocabulary score of each vocabulary in the text vocabulary set in the to-be-analyzed text in the domain semantic relation graph. By setting the semantic association relationship, the weight coefficient and the exclusive attribute, theflexibility and the pertinence are improved.

Description

technical field [0001] The present application relates to the field of information processing, in particular to a method and system for determining text domains based on domain semantic relationship graphs. Background technique [0002] With the rapid development of the big data era, online communities and social media have become gathering places for free and anonymous speech. Because online communities and social media have the characteristics of anonymity, convenience, and transcending time and space constraints. A large number of users can freely and freely share their opinions, insights and views on hot events on these network platforms. Real-time analysis of text data generated on the network platform at any time can grasp users' views and emotions on hot events in a timely manner, and detect bad speech and sudden public opinion among them. Timely and reasonable guidance to sudden public opinion and bad speech that arises at any time can effectively improve the secur...
