Abstract

The invention discloses a method and a device for generating a search engine selection abstract. The method comprises the following steps: identifying question and answer query words from search log data; obtaining a search result corresponding to the question and answer query word; if the search result does not contain the document of the specified type, taking the question and answer query wordsand the corresponding search result as input data, and outputting annotated candidate answers corresponding to the question and answer query words according to a machine reading understanding model;obtaining annotation answers corresponding to the annotation candidate answers based on active learning, and taking the annotation answers as selected abstracts of the corresponding question and answer query words in a search engine. According to the technical scheme, for the recognized question and answer query words, through the mode of combining machine reading understanding and active learning, a carefully-selected abstract that a user can directly view needed content in a search result page is provided for a search engine, the query cost and answer accuracy are both considered, and the use experience and search quality of the user are improved.
