Embodiment Construction

[0025] First of all, some nouns or terms appearing in the process of describing the embodiments of the present invention are applicable to the following explanations:

[0026] Machine learning is a method of converting data into information by extracting rules or patterns from data. The main machine learning methods include inductive learning and analytical learning. In the process of machine learning, data is first preprocessed to form features, and then some kind of model is created based on the features; machine learning algorithms analyze the collected data and assign weights, thresholds, and other parameters to achieve learning purposes.

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodimen...

Abstract

The invention discloses a method and device for obtaining correlated keywords of keywords. The method comprises the steps of receiving a request for obtaining the correlated keywords, conducting word segmentation on text information to obtain a word bank of multiple keywords, adopting a machine learning method to obtain multidimensional arrays corresponding to the text information, of the keywords in the word bank, conducting clustering analysis on the multiple keywords based on the multidimensional arrays corresponding to the keywords to obtain multiple word sets, determining the word sets including target keywords, calculating distances between the target keywords and second keywords which are keywords in the word sets including the target keywords except the target keywords, and using the second keywords corresponding to the distances meeting the preset conditions as the correlated keywords. By means of the method and device for obtaining the correlated keywords of the keywords, the problem of low speed of obtaining the correlated keywords of the keywords in the prior art is solved, and the effect of improving the correlated keyword obtaining speed is achieved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular, to a method and device for acquiring associated keywords of keywords. Background technique [0002] For a topic that people care about, if a keyword is given, the problem to be solved is how to quickly and effectively find the keyword with the strongest correlation with the given keyword in the text, for example, if the given keyword is "Tiananmen", Since the words that often appear together with "Tiananmen" include "Tiananmen Gate Tower", "Forbidden City" or "Tiananmen Square", the keywords related to the given keyword "Tiananmen Square" include "Tiananmen Gate Tower", "Forbidden City" and "Tiananmen Square". In order to solve the above problems, there are mainly two existing solutions: one is to find associated keywords based on the text matching similarity of a given keyword; the other is to search for related keywords based on the co-occurrence probability of a given key...
