Abstract

The invention provides a topic model-based software question and answer recommendation method and device. The method comprises the steps of obtaining a retrieval string of a user document according to a topic model and the user document of a software question and answer information base; obtaining at least one information document from the software question and answer information base according to the retrieval string; and obtaining the similarity of the information documents and the user document and carrying out software question and answer recommendation to a user according to the similarity. According to the topic model-based software question and answer recommendation method provided by the invention, by adopting a topic model-based retrieval string obtaining method, the accurate retrieval string can be automatically determined according to the content in a current operation document of a developer, so that the retrieval operation is simplified, the accuracy of the retrieval string is improved by combining and fully utilizing context information of the user document; the software question and answer recommendation effect is improved; the similarity is calculated for the information documents and the user document; the recommendation order is determined; and the software question and answer recommendation effect is further improved.

Description

technical field [0001] The invention relates to information technology, in particular to a method and device for recommending software questions and answers based on topic models. Background technique [0002] In various tasks such as software development and code writing, when technicians encounter problems that are difficult to solve, they usually use retrieval methods to search for relevant information on the Internet as a reference. [0003] Before searching, technicians need to set search keywords according to the problems they encounter, and input search keywords in search engines or related forums and data sharing websites to get search results. Technicians need to manually screen all the search results to determine the highly relevant information and then conduct further careful analysis to determine whether the problem can really be solved. [0004] Since manual screening consumes a lot of time and energy, and may be due to unreasonable keyword settings, technician...
