Problems solved by technology

[0003] However, at present, due to the limited ability of the natural language understanding module to analyze the user's operation instructions, the user is usually required to perform voice input according to a relatively short and relatively fixed sentence pattern, which limits the user's input freedom and flexibility

Embodiment Construction

[0031] Multiple embodiments disclosed in this specification will be described below in conjunction with the accompanying drawings.

[0032] As mentioned above, the analysis algorithms currently used in human-computer interaction systems have very limited ability to analyze user operation instructions. Specifically, for a single input by the user, only relatively short or relatively fixed sentence patterns are supported, otherwise parsing omissions or parsing failures may occur. For example, some parsing algorithms specify the information to be extracted sequentially. For example, in the scenario of buying coffee by voice, the user is guided through fixed multiple rounds of interaction to tell the information about the coffee he wants to buy. For example, first, the The voice assistant asked: "Hello, what kind of coffee do you want?" The customer replied "I need a large cup of Mocha". Need that kind of cup of coffee”, the customer replied “Large cup, no cream, half sugar”, at ...

Abstract

The embodiment of the invention provides an analysis method for a user operation instruction, and the method comprises the steps: obtaining an input text obtained through the recognition of a voice inputted by a user, carrying out the word segmentation of the input text, and obtaining a word segmentation sequence; respectively converting a plurality of segmented words related to the commodity description in the segmented word sequence into markers in a predetermined format to obtain a mixed sequence; obtaining a preset semantic template set, each semantic template including a predetermined combination arrangement of a plurality of semantic descriptors and corresponding to one operation type, the plurality of semantic descriptors including commodity descriptors corresponding to combinationsof the markers; performing cyclic analysis on the current sequence which is initially a mixed sequence based on the semantic template set, wherein any cycle analysis comprises the steps: interceptinga sequence part matched with a certain semantic template from the head of the current sequence, obtaining an operation instruction according to an operation type corresponding to the certain semantictemplate and a marker in the sequence part, and updating the current sequence.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular, relate to a method and device for parsing user operation instructions. Background technique [0002] More and more industries use human-computer interaction systems to provide services to users. For example, in the catering industry, a voice ordering system is used to provide users with meal ordering services, and for another example, in the transportation industry, an intelligent ticketing system is used to provide users with ticketing services. These human-computer interaction systems usually include several main functional modules such as speech recognition, natural language understanding, natural language generation, and speech synthesis. Among them, the natural language understanding module is the core part of the entire system, responsible for understanding user input and analyzing user operation instructions. For example, it is analyzed that the...
