Embodiment Construction

[0019] In image search, it has always been a difficult point to search for ambiguous search terms. Search words with vague meanings generally refer to polysemous words or search words with unclear directionality. For example, the search term "Li Na" can refer to the tennis player Li Na, but also to the singer "Li Na". As another example, the search term "airplane head" can be interpreted as "airplane head" or "airplane hair style". Because the semantics of the search terms are vague or may point to multiple semantics, it is difficult to obtain accurate search results. Therefore, how to search for vaguely meaningful search terms and obtain accurate search results has become an important issue.

[0020] Based on this, the embodiments of the present invention provide a search method and device, which can effectively improve the accuracy of search results and optimize the search results of search words with vague meanings.

[0021] In order to enable those skilled in the art to...

Abstract

The embodiment of the invention provides a searching method and device, and the method comprises the steps: determining a label semantic space vector corresponding to a retrieval keyword, wherein thelabel semantic space vector is used for describing semantics of the retrieval keyword; calculating tag semantic space characteristics of the retrieval keyword according to the tag semantic space vector, wherein the tag semantic space characteristics are used for describing the similarity between the retrieval keyword and a retrieval result; and according to the tag semantic space features, sortingthe search results corresponding to the retrieval keywords. According to the embodiment of the invention, the accuracy of the search result can be effectively improved, and the fuzzy search result ofthe search term is optimized.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a search method and device. Background technique [0002] In the existing image search methods, the search results are sorted by measuring the correlation between search terms and image retrieval results. The correlation between search terms and image retrieval results mainly includes text correlation and image correlation. Due to the complexity of image analysis algorithms, current image search methods use more text correlation to optimize search results. [0003] However, when calculating the textual correlation between the search term and the image search result, since the search term may have multiple meanings, although the search term frequently appears in the search result, the search result may not be the result expected by the user. For example, if a user searches for "airplane head", many pictures of airplane heads may be returned, but t...
