Abstract

The invention discloses a theme model construction method and device and a computer readable storage medium, and the method comprises the steps: carrying out the local theme model construction of a corpus of a home terminal, and obtaining the local theme word distribution corresponding to the corpus; and sending the local theme word distribution to a coordination terminal, so that the coordinationterminal merges the local theme word distribution received from each data terminal to obtain global theme word distribution, and obtains a global theme model according to the global theme word distribution matrix. According to the method and the device, the privacy information in each data end corpus is protected while the quality of the theme model is improved.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a topic model construction method, device and computer-readable storage medium. Background technique [0002] Topic Model is a statistical model used to discover abstract topics in a series of documents in the fields of machine learning and natural language processing. Hidden semantic discovery tools represented by topic models have been widely used in various applications. Building a high-quality topic model usually requires a large amount of text information. However, in practical applications, these text information are often distributed in different machines. Due to the privacy of the information, these text information cannot be obtained for topic model construction, resulting in The amount of text information that can be used to build a topic model does not meet the requirements, and the quality of the constructed topic model is not high. Contents of the in...
