[0100] Finite State Automata:

[0101]A finite state automaton is a 5-tuple (Q, g, f, s0, T), where Q is the finite set of states, g is the transition function, f is the failure function, s0 is the initial state, and T is the transition to state set. Its use includes two aspects: construction and assembly, and the working process mainly depends on three core functions: transfer function (g), failure function (f) and output function (output). The construction process of the AC machine is also the process of constructing the state set Q and the three core functions.

[0102] (1) Construct the steering function g:

[0103] def 2.2 (state path): In AC machine, if there is an ordered transfer function set from state A to state B, then the ordered transfer function set is called the path from state A to state B, and A is called th...

Abstract

The invention discloses natural language understanding method, comprising the steps that: a natural language is matched with a conceptual language symbol after receiving the natural language input by the customer, and then a conception is associated with the conceptual language symbol; a conception which is most suitable to the current language content is selected by being compared with the preset conception dictionary, and then whether the conception is ambiguous is judged; and if the answer is YES, the conception is obtained by a language data base, entering the next step; and if the answer is NO, the conception is obtained based on the principle of language content matched, entering to the next step; a core conception and a sub conception are obtained by a conception reorganization, wherein, the core language meaning of the core conception is defined by an operation of the computer while the sub language meaning of the sub conception is defined by the operation content of the computer; and the complete language meaning is obtained by combining the core language meaning with the sub language meaning. The invention also provides a human-computer interaction intelligent system based on the method provided by the invention. The invention recognizes the natural sound input by the customer more accurately, thereby providing the customer with more intelligent and perfect services.

Description

technical field [0001] The invention relates to human-computer interaction technology, in particular to a natural language understanding method and a human-computer interaction intelligent system. Background technique [0002] Enterprise business services characterized by automatic voice and artificial intelligence have been carried out in China for many years. With the development of the Internet and mobile networks, enterprise business online applications have become a new window and medium for enterprises. The customer contact mode of existing business applications, such as relying on traditional manual telephone answering and static one-way corporate websites, has become less and less suitable for the business requirements of enterprises in the Internet era. Here comes the challenge: [0003] With the intensification of market competition, companies continue to launch new products and services. As an important department to contact customers, the customer service cent...
