Embodiment 1

[0050] Such as figure 1 As shown, the text similarity determination method provided by the embodiment of the present invention includes:

[0051]S101, representing the name of the unit in the predetermined knowledge base in pinyin;

[0052] S102, receiving the text input by the user, extracting the unit name in the received text and expressing it in pinyin;

[0053] S103, matching the unit name in the text expressed in pinyin with each unit name in the knowledge base expressed in pinyin one by one, and calculating the similarity of the longest common subsequence based on pinyin;

[0054] S104, sort the knowledge in the knowledge base according to the obtained similarity of the longest common subsequence based on pinyin, and select a piece of knowledge from the knowledge base that is closest to the text input by the user, wherein each Articles of knowledge include: unit name.

[0055] In the text similarity determination method described in the embodiment of the present inve...

Embodiment 2

[0111] The text similarity determination method described in this embodiment is applied to the field of intelligent customer service. Specifically, based on the text similarity determination method described in this embodiment, a 114 query intelligent customer service dialogue system is developed, such as Figure 4 As shown, the system includes: a softswitch system, a speech recognition system, a speech synthesis system and an intelligent semantic dialogue engine; wherein,

[0112] (1) The softswitch system includes the following parts:

[0113] 1) Session Initiation Protocol voice gateway: according to the type of trunk access, a corresponding Session Initiation Protocol (Session Initiation Protocol, SIP) voice gateway device can be selected.

[0114] 2) Proxy server: The proxy server can be a general-purpose personal computer server (Personal Computer Server, PC Server), which is responsible for processing SIP signaling access, realizing call routing distribution and load sh...

Abstract

The invention provides a text similarity determination method which can improve matching accuracy. The method comprises the steps of expressing pre-determined unit names in a knowledge base with spelling; receiving text input by a user, and extracting unit names in the received text and using spelling to express the unit names; performing one-to-one matching on the unit names in the text expressed with the spelling and each unit name in the knowledge base expressed with spelling, and calculating similarity of a longest common subsequence based on spelling; sorting knowledge in the knowledge base according to the similarity of the longest common subsequence based on spelling, and selecting from the knowledge base one piece of knowledge closest to the text input by the user, wherein each piece of knowledge includes unit name. The invention relates to the field of artificial intelligence.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to a method for determining text similarity. Background technique [0002] At present, natural language processing is a difficult and attractive research topic in the field of artificial intelligence. The ideal result is to enable computers to understand and analyze natural language like humans, so as to solve text classification, syntax analysis, semantic understanding, and emotion recognition. , semantic reasoning and other practical issues. [0003] In the field of intelligent dialogue engines, it is difficult to achieve accurate speech recognition due to problems such as different customer accents and volume, especially when the voice quality of telephone communication is not high. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a text similarity determination method to solve the problem of low speech recognit...
