A framework for rapid development of conversational natural language call routing systems for call centers

چکیده
A framework for rapid development of conversational natural language call routing systems is proposed. The framework cuts costs by using only scantily prepared business requirements to automatically create an initial prototype. Besides clear targets (terminal routing classes), vague targets which are variations of users’ incomplete (semantically overlapping) sentences are enumerated. The vague targets can be derived from the confusion set of the semantic tokens of the clear targets. Also automatically generated for a vague target is a disambiguation dialogue module, which consists of a prompt and grammar to guide the user from a vague target to one of its associated clear targets. In the final analysis, our framework is able to reduce the human labor associated with developing an initial natural language call routing system from a few weeks to just a few hours. The experimental results from a deployed pilot system support the feasibility of our proposed approach.

With the developments of new technologies appearing very quickly, the attention has been focused more on technology than learning. English centers and institutes have mostly been busy accommodating new programs and technologies and hence have not spent enough time to evaluate the CALL programs and technologies employed to find their affordances and limitations. The present study was an attempt ...

Computers have been used for language teaching ever since the 1960's.Learning a second language is a challenging endeavor, and, for decades now, proponents of computer assisted language learning (CALL) have declared that help is on the horison.

We present a new integrated approach for natural language call routing based on stochastic language models. The system learns automatically from examples to direct a call to the appropriate destination within a call center. It employs stochastic language models for each call destination. The language models are generated by a language model adaptation algorithm based on the minimum discriminati...
