Abstract

The application discloses an information acquisition method and device. An embodiment of the method includes: acquiring a plurality of question-answer pairs in a data set, extracting at least one question word and at least one answer word of each question-answer pair; determining a context of the question word and the answer word; taking the question word, the answer word and the context as a training sample, training a preset model, and obtaining a word vector set; receiving question information to be responded; based on the word vector set, acquiring answer information matching the question information from the data set. The information acquisition method and device may train the word vector through evaluating a correlation of the question-answer pairs from a semantic aspect, and a training speed and accuracy of the word vector are improved. Based on that when the word vector acquires the matched information, a complicated supervised neural network training is not needed, the speed and accuracy of information acquisition can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of terminal technology, and in particular to an information acquisition method and device. Background technique [0002] At present, people mainly use search engines to obtain information on the Internet. Users need to browse a large number of web pages to obtain answers, which is inefficient. In-depth question answering technology makes search more intelligent, provides users with more accurate answers, and reduces the cost for users to obtain information. With the development of online Q&A sites such as "Baidu Zhizhi", a large amount of data in the form of Q&A generated by users has been generated, which provides data support for in-depth Q&A. [0003] However, the quality of these Q&A pairs varies, mainly including the following two types of questions: "escaping" and "verbosity". "Escape" means that the main content of the answer is irrelevant to the qu...
