Abstract

The invention discloses an automatic document classification method. The method comprises the following steps: constructing a dictionary database; obtaining the keywords of the documents to be classified; searching in the dictionary database according to the keywords of the documents to be classified, and obtaining the classification number information of the keywords of the documents to be classified; according to the classification number information of the keywords of the documents to be classified, the classification number of the documents to be classified is determined, and the automaticclassification of the documents is realized. The method of the invention can realize fast automatic classification of documents.

Description

technical field [0001] The invention relates to the field of document classification, in particular to an automatic document classification method. Background technique [0002] With the development of electronic periodicals, the classification and indexing of digital documents has long been done manually by catalogers, which is time-consuming and laborious. Moreover, due to the ambiguity of information and the sharp increase in the types and quantities of digital documents, it is unrealistic to ensure the accuracy of document classification and indexing only by improving the professional quality of cataloguers. However, by directly filtering and classifying the document information through the computer, and submitting the part that the user really needs to the user, the user can be freed from the cumbersome document processing work, and different types of documents can be distinguished more quickly, so that a large number of unordered The systematization of documents great...
