Abstract

Analyzing transcripts of conversation between at least two users by receiving input information from a first user via a voice call, creating conversational transcripts from the information received from the first user, selecting at least one defined situation from a list of defined situations, identifying the selected situation in the conversational transcripts, identifying a set of procedural sequences by comparing the at least one identified situation in the conversational transcripts with knowledge derived from a corpus of historical conversational transcripts; and providing the set of procedural sequences to the first user.

12. A method for creating a document of procedural sequences, the method comprising:

receiving input information from a first user;

creating conversational transcripts from the information received from the first user;

identifying at least one defined situation in the list of defined situations from the conversational transcripts;

comparing the situations with knowledge derived from historical conversational transcripts in a corpus;

on negative determination

creating a document comprising a set of procedural sequences; and

adding the document created to a repository; and

prompting a second user on creating a set of procedural sequences based on the defined situation

wherein knowledge derived from a corpus of historical conversational transcripts comprises;

clustering textual segments in the corpus of historical conversational transcripts into groups of related textual segments;

representing each of the groups of related textual segments by a representative syntax;

forming a sequence of representative syntax for each historical conversational transcript in the corpus;

finding frequently occurring sub sequences from the sequences of representative syntax; and

finding distinct and long frequently occurring sub sequences from the frequently occurring sub sequences,

wherein clustering the textual segments in the corpus of historical conversational transcripts further comprises;

organizing the historical conversational transcripts into groups of conversational transcripts according to a defined criteria; and

clustering the groups of conversational transcripts to obtain groups of related textual segment,

wherein clustering groups of conversational transcripts to obtain groups of related documents further comprises;

generating at least two sets of documents from the groups of conversational transcripts, wherein each of the sets of documents corresponds to at least one of the users,

wherein each of the representative syntax comprises a segment of conversational transcripts belonging to each of the group of related textual segments,

wherein each of the representative syntax comprises a set of frequent and distinct words in each of the group of related textual segments,

wherein finding distinct and long frequently occurring sub sequences is performed by a clustering algorithm belonging to the class of leader clustering algorithm,

wherein the corpus of historical transcripts comprises a repository, and

wherein clustering textual segments in the corpus of historical conversational transcripts into groups of related textual segments comprises utilizing a set of configurable cluster parameters to cluster the textual segments based on normalized entropy values.
