A few of classes often occupy large proportion of vocabulary in speech recognition for many information query dialog system,which can be used to improve traditional search algorithm based on single lexicon tree.

Research on after service response system for medical equipment;

First a drive system and corresponding response system are built up respectively on the transmitting terminal and receiving terminal.

This paper focuses on the research of the problem of linear generalized synchronization of chaotic systems,and develops a new method——adaptive control for constructing a response system to implement linear generalized synchronization with the drive system.

Refer to the Grice cooperative principle and conversational maxim,an appropriate maxim of system response is defined as follows: feed back information correctly,offer suggestive information neither more nor less,and express in spoken as natural as possible.
