Application ID: 12566369

Base Claim:
1. A computer implemented method for creating a call routing system, the computer implemented method comprising: receiving a set of initial target classes and a corresponding set of topic descriptions; identifying non-overlapping semantic tokens from the set of topic descriptions; identifying a set of clear target classes from the non-overlapping semantic tokens and the set of initial target classes; identifying overlapping semantic tokens from the set of topic descriptions; identifying a set of vague classes from the overlapping semantic tokens and the initial target classes; generating a set of disambiguation dialogues and a set of grammar prompts according to the non-overlapping semantic tokens; and creating the call routing system based on the set of clear target classes, the set of vague target classes, and the set of disambiguation dialogues.

Claim 2:
2. The computer implemented method of claim 1 , further comprising: identifying the non-overlapping semantic tokens, wherein the non-overlapping semantic tokens are semantic tokens appearing in only one of the set of topic descriptions; and identifying the overlapping semantic tokens from the set of topic descriptions, wherein the overlapping semantic tokens are semantic tokens appearing in a plurality of the set of topic descriptions; identifying the set of vague classes from the overlapping semantic tokens and the set of initial target classes, wherein each of the set of vague classes corresponds to a plurality of the set of clear target classes; and generating the set of disambiguation dialogues and the set of grammar prompts according to the non-overlapping semantic tokens, wherein the disambiguation dialogues is generated from the non-overlapping semantic tokens to distinguish among ones of the plurality of the set of clear target classes.
