Problems solved by technology

When Internet users obtain relevant answers to such yes / no questions, they can only obtain scattered relevant webpages through search engines, and then manually filter irrelevant webpages and analyze the answer viewpoints by themselves. The efficiency of data analysis or processing of retrieval results is low

Abstract

The invention provides a data processing method and device for retrieval. The method comprises the following steps: acquiring a question and page data including an answer of the question, wherein the question is a question of which the answer is positive or negative; generating a question-answer template pair <question, answer> which is paired with the question according to the question and the page data; extracting more than one answer segment from the page data according to the matching degrees between the question and the answer segments in the page data; and determining that the viewpoint of the more than one answer segment is positive or negative according to the quantity of negative demonstrative words of the extracted more than one answer segment and the quantity of negative demonstrative words of the question. Through adoption of the method and device, the data processing efficiency of the retrieval results of yes / no questions is increased greatly.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a data processing method and device for retrieval. Background technique [0002] When searching through the Internet or online resources such as question-and-answer communities, forums, and encyclopedias, there are usually questions such as "Can pregnant women eat watermelon", "Is it okay to use mineral water to make milk for babies", etc. The answer to the question is usually "yes (YES, affirmation)" or "no (NO, negation)", which we call a yes / no question (also known as a YES-NO question or a polarity question). When Internet users obtain relevant answers to such yes / no questions, they can only obtain scattered relevant webpages through search engines, and then manually filter irrelevant webpages and analyze the answer viewpoints by themselves. The efficiency of data analysis or processing of retrieval results is low. Contents of the invention [0003] In order to solve the above...
