[0003] In addition, the above-mentioned traditional classification methods cannot add new words on the Internet in real time. When a user enters a new query sequence, relevant search resources corresponding to these new words may not be provided to the user, which greatly affects the retrieval recall. Rate

The invention provides a device and a method for confirming query sort of a query sequence. The method comprises the following steps: acquiring the query sequence the query sort of which is to be confirmed; expanding the query sequence so as to acquire an expansion vector corresponding to the query sequence; matching the expansion vector with a plurality of query sorts for acquiring the relevance between the expansion vector and the query sorts; and confirming the query sort of the query sequence according to the relevance. Compared with the prior art, the method comprises the steps of expanding the query sequence, matching the expansion vector with a plurality of query sorts and confirming the query sort of the query sequence according to the relevance between the expansion vector and the query sorts, the searching accuracy and recalling rate are obviously increased, and the user experience is enhanced.
Description
technical field [0001] The present invention relates to natural language processing technologies, and in particular to technologies for determining query categories of query sequences. Background technique [0002] In the prior art, when classifying a user's query sequence, it is often simply identified through a static proper noun dictionary combined with a query category requirement suffix. However, this classification method relies too much on the accuracy and recall rate of proper noun mining in the dictionary, and the proper nouns are relatively fixed, which cannot really meet the requirements of user query classification. The recall rate and accuracy rate here are two metrics widely used in the fields of information retrieval and statistical classification, and are used to evaluate the quality of retrieval or statistical results. The recall rate refers to the number of relevant documents retrieved and all document databases. The ratio of the number of related document...
