Abstract
Abstract A system generates a query using an entity extractor, a categorizer, a query generator, and a short run aspect vector. The entity extractor identifies a set of entities in selected document content for searching information related thereto using an information retrieval system. The categorizer defines an organized classification of document content with each class in the organization of content having associated therewith a classification label that corresponds to a category of information in the information retrieval system. The categorizer assigns the selected document content a classification label from the organized classification of content. A query generator formulates a query that restricts a search at the information retrieval system to the category of information in the information retrieval system identified by the assigned classification label. The short length aspect vector generator generates terms for further refining the query using context information surrounding the set of entities in the selected document content.

Claim 3
Dependent Claim
29 words
The method according to claim 1 , further comprising limiting the query by adding terms relating to context information surrounding the set of entities in the selected document content.
Claim 4
Dependent Claim
19 words
The method according to claim 2 , wherein the number of terms added is limited to a predefined number.
Claim 5
Dependent Claim
20 words
The method according to claim 2 , further comprising limiting the query by adding terms defining the assigned classification label.
Claim 6
Dependent Claim
20 words
The method according to claim 1 , wherein the organized classification of document content is defined using a hierarchical organization.
Claim 7
Dependent Claim
25 words
The method according to claim 1 , further comprising using a text categorizer to assign the classification label assigned from the organized classification of content.
Claim 8
Dependent Claim
43 words
The method according to claim 6 , further comprising: extracting with the text categorizer a set of terms relating to the document content; and appending to the query ones of the set of terms extracted by the text categorizer to contextualize the query.
Claim 9
Dependent Claim
25 words
The method according to claim 7 , further comprising abbreviating the set of terms extracted by the text categorizer to a predefined number of terms.
Claim 10
Dependent Claim
147 words
The method according to claim 8 , wherein said abbreviating comprises: extracting noun phrases from the selected document content; ranking the noun phrases by those that occur most frequently in the document content; defining a subset of noun phrases by identifying those ranked noun phrases that occur more frequently than a first predefined frequency; ranking those words in the subset of noun phrases by their frequency of occurrence to define an ordered list of words; defining a subset of the ordered list of words by identifying those ranked words that occur more frequently than a second predefined frequency; re-ranking the subset of words in inverse frequency to their use in the category of information in the information retrieval system identified by the assigned classification label; using only those highest ranked words in the re-ranked subset of words to define the set of terms appended to the query.
Claim 11
Dependent Claim
