example 1

[0069] Example 1: The intent core word "weather" can be modified with the intent modifiers "time" and "place" to combine to obtain the intent of the query sentence. For example, the core word of the intent of the query sentence "what's the weather in Beijing tomorrow" is "weather", and the modifiers of the intent are "Beijing" and "tomorrow". Therefore, the intent of the query sentence is "the weather in Beijing tomorrow".

example 2

[0070] Example 2: The intent core word "train number" can be modified with the intent modifiers "departure station", "terminal station" and "time" to combine to obtain the intent of the query sentence. For example, the intent core word of the query sentence "how many trains depart from Beijing to Harbin on October 20" is "train frequency", and the intent modifiers are "10.20", "Beijing" and "Harbin". Therefore, the query can be obtained The intent of the statement is "10.20 Beijing-Harbin train schedule".

[0071] Optionally, as in Figure 4 As shown, the intention analysis method of the embodiment of the present invention may further include the following steps:

[0072] S15: After the intent of the sentence is determined, perform a search according to the intent, and obtain a search result that meets the intent.

[0073] In this embodiment, after determining the intent of the query statement, the search engine can perform a search according to the obtained intent, and obta...

Abstract

The present invention proposes an artificial intelligence-based intent analysis method and device, wherein the method includes: receiving an input sentence; using a preset strategy to obtain the intent core words of the sentence; according to the intent core words, obtaining the intent of the sentence based on a syntactic structure tree Modifiers; determine the intent of the sentence based on the core words of intent and modifiers of intent. The invention can realize the intent analysis of query sentences in various fields, solve the problem of limited intent analysis field in the prior art, expand the range of intent analysis, and improve the efficiency of intent analysis.

Description

technical field [0001] The present invention relates to the field of Internet technologies, in particular to an artificial intelligence-based intent analysis method and device. Background technique [0002] Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It 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. Among them, natural language processing is an important research aspect of artificial intelligence, and it is also widely used in search engine technology. [0003] With the rapi...
