Abstract

The invention discloses a specialized vocabulary meter dynamic generating system, which is characterized by the following: basing on theme semantic vector; proceeding professional sort or cluster document sort module and specialized vocabulary meter generating module for correspond document; extracting finite quantity and a professional sort document text with the specialized vocabulary meter; calculating weight for all vocabulary in the text; ordering with the size of the weight value; choosing the front N vocabulary as specialized vocabulary meter of relative professional sort. This invention also disclose a specialized vocabulary meter dynamic generating method. This invention possesses high accuracy and low cost, which can proceed dynamic updating maintenance for specialized vocabulary meter.

Description

technical field [0001] The present invention relates to network communication technology, and more specifically, relates to a system and method for dynamically generating professional vocabulary. Background technique [0002] Professional domain vocabulary refers to the collection of vocabulary in a certain professional category. In the field of natural language processing, this information is very helpful for such as search and semantic related calculations. At this stage, it is generally collected manually by a dedicated person. Obviously, the method of manually constructing a professional vocabulary is a waste of manpower and material resources. In addition, manual construction of the vocabulary depends on the knowledge of the input person, and there may be many words that have not been recalled. In addition, vocabulary is constantly changing, and manual entry requires a continuous investment in newly created vocabulary, which is too costly. Contents of the invention ...
