Apparatus and method for determining information retrieval applicability and generating best case for determination

A method for determining applicability of an information retrieving process, comprising:

• acquiring voice data in which a conversation including necessary information about an information retrieving process to be determined is recorded;
• acquiring retrieval history data including a retrieval key used in the information retrieving process to be determined, a selected document indicating a document selected by a retrieval result, and an order in a retrieval result of the selected document;
• extracting an expression matching a keyword in the keyword storing unit storing a keyword indicating necessary information in the information retrieving process from the voice data, defining the extracted expression as a keyword obtained before retrieval;
• extracting best case data having a keyword matching the keyword obtained before retrieval from a best case storage unit for storing best case data including a keyword indicating information about a best execution example of an information retrieving process and necessary information for the information retrieving process acquired before the information retrieving process, a retrieval key used in the information retrieving process, a selected document indicating a document selected from among retrieval results, and an order of the selected documents in the retrieval results;
• and
• determining the applicability of the keyword obtained before retrieval in the information retrieving process to be determined and the applicability of the retrieval history data based on the extracted best case data;
• and
• obtaining the applicability of the information retrieving process to be determined based on the applicability of the keyword obtained before retrieval and the applicability of the retrieval history data.

An apparatus for supporting an information retrieving process of an operator, comprising:

• a keyword storage unit for storing a keyword indicating necessary information for an information retrieving process;
• a best case storage unit for storing best case data including a keyword indicating information about a best execution example of an information retrieving process and necessary information for the information retrieving process acquired before the information retrieving process, a retrieval key used in the information retrieving process, a selected document indicating a document selected from among retrieval results, and an order of the selected documents in the retrieval results;
• a voice data acquisition unit for acquiring voice data in which a conversation including necessary information about an information retrieving process is recorded;
• a unit for extracting information obtained before retrieval for extracting an expression matching a keyword in the keyword storage unit from the voice data, and defining the extracted expression as the keyword obtained before retrieval;
• a best case retrieval unit for extracting best case data having a keyword matching the keyword obtained before retrieval from the best case storage unit;
• and
• a best retrieval key candidate presentation unit for acquiring from the extracted best case data a retrieval key of the best case data having the best order of retrieval result of the selected document and presenting the acquired retrieval key as a candidate for the best retrieval key for the selected document.
