Abstract

The invention discloses a text pattern recognition method, comprising the following steps: according to the dichotomy algorithm, a preset position of a text file is obtained as a base point, and the number of occurrences of each keyword in the text file and relative to the base point are recorded position; according to the number of times and the position of the keywords recorded in the text file, the text file is mapped to a star-shaped directed weighted graph; according to the dichotomy algorithm, the star-shaped directed weighted graph is transformed into Simplify the star-shaped directed weighted graph; according to the attributes of the simplified star-shaped directed weighted graph and the number of occurrences of the recorded keywords, the text file is mapped to a text feature vector, and the entire operation process is simple and effective, thereby facilitating rapid Text Analysis.

Description

technical field [0001] The invention belongs to the technical field of text recognition, and in particular relates to a text pattern recognition method and system for accessing a wireless network. Background technique [0002] With the development of the network, how to quickly obtain useful information from a large number of texts has become one of the important research topics in the field of information technology and pattern recognition technology. When implementing the text pattern recognition technical solution, it is necessary to abstract the text file into a model that can be operated by a computer. The text pattern recognition method in the prior art usually constructs a directed weighted network model by calculating the distance between two keywords, and simplifies the directed weighted network model through weighting processing, and finally obtains the matrix of the simplified network model , and propose the feature vector of the text. However, the model constru...
