Problems solved by technology

However, the above method wastes human resources due to the need for manual editing and accumulation, which is not conducive to automatic realization, and because the template is not flexible enough, it can only recognize sentences in a fixed format, which leads to poor recognition of semantic fragments and poor query retrieval. The result does not meet the user's needs

Embodiment Construction

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0025] The various embodiments of the present invention aim at the prior art, which usually uses manually edited templates to mine query semantic fragments. Due to the need for manual editing and accumulation, human resources are wasted, which is not conducive to automatic implementation, and because the templates are not flexible enough, they can only identify Fixed-format sentences lead to poor recognition of semantic fragments, and the retrieval results of query cannot meet the needs of users. An artificial intelligence-based m...

Abstract

The invention puts forward a method and device for obtaining semantic segments of queries based on artificial intelligence and a terminal. The method comprises the following steps: pre-processing obtained queries and determining first subject words and semantic segment sets of queries; determining degrees of relevancy among all semantic segments of the semantic segment sets and the first subject words according to retrieval of historical data; filtering the semantic segment sets according to degrees of relevancy among all semantic segments and the first subject words and determining target semantic segment sets corresponding to queries. Therefore, target semantic segment sets corresponding to queries are obtained. There is no need to use manpower to edit and extract templates, which saves manual resources and is conducive to realization of automation. The mode of obtaining semantic segments is flexible and can adaptively mine all granularities of semantic segments. Therefore, recognition effect of semantic segments is enhanced and therefore retrieval results of query can better meet needs of users and improve user experience.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an artificial intelligence-based method, device and terminal for acquiring semantic segments of retrieval sentences. Background technique [0002] Artificial Intelligence (AI for short) is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a manner similar to human intelligence. Research in this field includes robotics, language recognition, image recognition, natural language processing and expert systems, etc. [0003] In the retrieval sentence (query) semantic understanding technology, the semantic information of the query is usually structured in the form of intent and slot. Among the...
