ALICE: acquisition of language in conversational environment-an approach to weakly supervised training of spoken language system for language porting

摘要

A conversational second language acquisition system is proposed which aims to reduce the work required for the language porting of a spoken language system. This system needs only a small lexicon in the initial stage. It needs neither hand-description of rules nor the collection/annotation of a large corpus. It refers the corpus of semantic frames which is obtained through development/use of the first language version of the system. Then, it makes hypotheses which lead to reasonable semantic frames and parse the sentence with them. The system drives the back-end system with the interpretation and confirms whether the result is suitable for the user. With the above process, weakly supervised training of the spoken language system is realized.
