TF-IDF assumes that each participle term in the text is independent and has no correlation with each other. Moreover, for search terms that retrieve product or service information, since the search terms are usually short texts, most of them will appear in TF = 1, resulting in the determination of the weight of each participle term in the query based on TF-IDF, and the retrieved recall results do not have a high matching degree with the product or service

The embodiment of the invention discloses an object weight determination method and device, electronic equipment and a readable storage medium. The object weight determination method comprises the steps: acquiring a preset operation historical result data set comprising preset operation historical result data and historical object data related to the preset operation historical result data; carrying out aggregation calculation on a preset operation historical result data set, determining the weight value of a preset operation historical result element unit, whereinthe preset operation historical result element unit is the combination of two or more preset operation historical result elements continuously appearing in the preset operation historical result data; and obtaining the target object, comparing the target object with the preset operation history result element unit, and determining the weight value of the preset operation history result element unit corresponding to the targetobject as the weight value of the target object. According to the technical scheme, the proper commodity or service can be matched based on retrieval of the weight value of the target object, and therecall rate of the commodity or service is improved.
Description
technical field [0001] The present disclosure relates to the technical field of computer applications, and in particular to a method, device, electronic equipment and readable storage medium for determining an object weight. Background technique [0002] With the development of Internet technology, more and more merchants or service providers provide services to users through Internet platforms. By inputting a query word (query) in a search engine, a user obtains relevant product or service information based on the search word. During the entire search process, the correlation between the product or service information obtained according to the search term (for example, product name, business name or brand, etc.) and the search term largely depends on the weight of the word segmentation term (term) of the search term. Therefore, how to determine the weight of participle terms is very important. [0003] In the prior art, when calculating the weight of each term in a query ...
