Embodiment Construction

[0023] The technical content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, the present invention provides a method for calculating semantic relationship closeness, including the following steps: performing word segmentation processing on documents, and filtering the word collection obtained after processing, filtering out non-nouns and common nouns with no real meaning; The word set is weighted according to the position information in the metadata text; finally, the semantic relationship closeness SRC (Semantic Relational Closeness) value between the two feature words is calculated. The following is a detailed description of this process.

[0025] S1, perform word segmentation processing on the document, and filter the word set obtained after processing, and filter out non-nouns and common nouns without meaning.

[0026] In order to reduce the comp...

Abstract

The invention discloses a method for calculating semantic closeness, which includes the following steps: S1, performing word segmentation processing on documents, and filtering the word collection obtained after processing, and filtering out non-nouns and common nouns with no real meaning; S2, The filtered word set is weighted according to the position information in the text, and its co-occurrence frequency weight is calculated; S3, according to the average weight between two words, the semantic relationship closeness is calculated. The invention fully considers the distance between two words and the context relationship thereof, and improves the accuracy of word correlation judgment.

Description

technical field [0001] The invention relates to a method for calculating the closeness of semantic relationship, in particular to a method for quantitatively calculating the closeness of semantic relationship between words, which belongs to the technical field of natural language processing. Background technique [0002] The rapid development of the Internet has brought human beings into a society of information explosion. Faced with the massive amount of information on the Internet, people often use search engines to obtain and locate effective information. Most of the currently widely used commercial search engines use an information retrieval model based on the combination of keyword matching and Boolean operations. Retrieval keywords become the most important communication channel between users and retrieval systems. However, only matching a small number of keywords input by users cannot obtain satisfactory retrieval results. [0003] In order to obtain better retrieva...
