Problems solved by technology

[0004] However, there is a problem of inaccurate recognition in the method of using the vocabulary to analyze the core product words in the title. For example, the word "Xiaomi" has different meanings in different contexts: one is the brand word "Xiaomi mobile phone", and the other is Product word "millet porridge"
It is impossible to distinguish these two meanings simply by using a vocabulary, so the recognition of core product words is inaccurate

Abstract

The invention discloses an identification method and device for a core product word in a title, and relates to the technical field of computers. When a word2vec model generates a word vector of a word, previous and next words adjacent to the word or words near the word in the title can be referenced, and therefore word vectors generated by the same word in different contexts are different; meanwhile, the n-gram characteristics of the product word contain the previous and next words adjacent to the product word or the words near the product word in the title, the context of the product word can be expressed, and therefore the n-gram characteristics are obtained by the same word in different contexts are different; accordingly, word vector expressions for the n-gram characteristics are different, results obtained when identification is conducted through a core product word identification model are different, the ambiguity problem of identification of the core product word in the title is solved, and the accuracy rate is increased.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for identifying core product words in a title. Background technique [0002] Sentence component analysis refers to the use of various methods to mark the basic components of sentences. Sentence component analysis is one of the basic problems in natural language processing and has a wide range of applications. E-commerce title component analysis is a branch of sentence component analysis, which is widely used in intent recognition, personalized ranking and other fields. But because the title is a pile of words (no subject, predicate verb, etc.), it is more complicated. [0003] The core product word in the title refers to the specific product involved in the title. For example, the core product word in the Korean version of casual pants men’s clothing is trousers. Identifying the core product word in the title is a major method for sentence composition anal...
