Problems solved by technology

However, for application systems in specific fields (such as: weather, flight, accommodation, transportation, tourism, air tickets, train ticket ordering, etc.), such a method is not optimal, because it does not make full use of the high-level semantic information in these fields

Embodiment

[0052] 1. According to the syntax characteristics of the telephone dialing system, establish the "grammatical concept" of the dialing system. For example: according to the syntactic features of "dial-up system", establish the "grammatical concept" of "dial-up system". Such as 【start】, 【modal particle】, 【dial】, 【person's name】, 【place name】, 【telephone】, 【number string】etc.

[0053] 2. From the "grammatical concept", the grammatical rules containing the high-level semantic information of the telephone dialing system are established. For example: 【Start】->【Modal Particle】|【Dial】, 【Dial】->【Person Name】|【Place Name】|【Number String】.....

[0054] 3. According to grammatical rules and "grammatical concepts", a hierarchical grammatical model is established. For example: the grammatical model of the "Dialing System" we developed mainly utilizes three layers of the layered grammatical model introduced earlier.

[0055] Main grammatical layer: start -> modal particle|dial, dial -> na...

Abstract

The invention is a method of establishing semantic analyzer based on syntactic model in the field of intelligent information processing, using high-layer semantic information of a telephone dial system to establish a syntactic model, and applying the syntactic model to semantic analysis, automatically splitting phonetic stream, organically combining phonetic-Chinese character conversion with voice analysis, including two aspects of syntactic model establishment and semantic analysis. It advances a method of using high-layer semantic information in a syntactic model to split the phonetic stream. It is a semantic analyzer able to eliminate ambiguity and split sentences. It can perfectly analyze the semantic information of the sentences in or out of the grammatical rule.

Description

technical field [0001] The invention relates to a method for establishing a semantic analyzer in the technical field of intelligent information processing, in particular to a method for establishing a semantic analyzer based on a grammar model. Background technique [0002] A typical dialogue system consists of modules such as speech recognition, natural language understanding, dialogue management, natural language generation, and speech synthesis. The research on the natural language understanding module has a long history, and the current research mainstream is to use the rule-based language understanding method to realize it, that is, to analyze the syntax and semantics according to the existing grammar, and its basis is the formal language theory. Common natural language understanding modules mainly use Context Free Grammar (CFG) to describe and analyze written language. Compared with written language, spoken language has its own characteristics: the sentence structure ...
