Problem isolation through weighted search of knowledge bases
First Claim
1. A computer program product for problem isolation through a weighted search of knowledge bases, the computer program product comprised of:
- a computer usable storage medium having computer usable program code embodied therewith, the computer usable program code comprising;
computer useable program code configured to perform multiple searches of said knowledge bases using keywords extracted from records, said records being related to a technical problem within a computer system, said keywords being used to identify pertinent documents contained within said knowledge databases, each of said pertinent documents containing a subset of said keywords;
computer useable program code configured to generate an aggregate relevance index associated with each of said pertinent documents, said aggregate relevance index being a composite of a keyword count which captures significance of searched keywords to said records as a whole and a search rank index which captures overall relevance of each of said pertinent documents over all searches for said searched key words;
said search rank index comprising a ratio which includes a search rank of a said pertinent document among all documents returned in a given search and a total number of documents returned in said given search;
wherein said aggregate relevance index comprises a sum of the search rank index for a said pertinent document across each search for each of said keywords, said aggregate relevance index being equal to the product of said search rank index and said keyword count summed over all keyword searches.

Abstract
A computer program product for problem isolation through a weighted search of knowledge bases includes computer useable program code that generates an aggregate relevance index which ranks the search results. The aggregate relevance index is calculated using a measure of relevance of each of said pertinent documents across all keyword searches. A method for problem isolation through the weighted search of knowledge bases comprises searching knowledge bases using extracted keywords to identify pertinent documents contained within said knowledge databases; and generating a global rank associated with each of the pertinent documents, the global rank being calculated using a measure of the relevance of each of the pertinent documents across all keyword searches and a measure of the relevance of each of the keywords to the records as a whole.

9. A method for problem isolation through a weighted search of knowledge bases comprising:
-
obtaining keywords, said keywords being extracted from records, said records being related to a technical problem within a computer system; searching said knowledge bases using said keywords to identify pertinent documents contained within said knowledge databases, each of said pertinent documents containing a subset of said keywords; generating a global rank associated with each of said pertinent documents, said global rank comprising a measure of relevance of each of said pertinent documents across all keyword searches and a measure of relevance of each of said keywords to said records as a whole, the global rank comprising an aggregate relevance index generated by; summing a rank for each of said pertinent documents across each search for each of said keywords to produce a search rank index, the search rank index comprising a ratio which includes a search rank of a said pertinent document among all documents returned in a given search and a total number of documents returned in said given search, the search rank capturing the relevance of each of said pertinent documents across all keyword searches; multiplying said search rank index by a keyword count to produce a weighted search rank, the keyword count capturing relevance of each of said keywords to said records as a whole; and summing said weighted search rank index over all keyword searches to produce the aggregate relevance index. - View Dependent Claims (10, 11)
