Method and apparatus for generating and utlizing annotations to facilitate computer text retrieval
DCFirst Claim
1. A method for facilitating computer text retrieval comprising the steps of:
- selecting subdivisions for the text;
generating for each of said subdivisions which is to be recovered at least one annotation containing words having a selected annotator determined relationship and being in a language selected from the group of a natural language and an artificial language;
storing the annotations in a predetermined structured form which retains said selected relationship, the stored annotations being readable by a computer to search for desired annotations; and
adding to the stored annotations a connection to corresponding text.

Abstract
A method and apparatus for computer text retrieval which involves annotating at least selected text subdivisions, preferably with natural language questions, assertions or noun phrases. However, the annotations may also initially be generated in a structured form. Annotations are, if required, converted to a structured form and are stored in that form. Searching for relevant text subdivisions involves entering a query in natural language or structured form, converting natural language queries to structured form, matching the structured form query against stored annotations and retrieving text subdivisions connected to matched annotations. The annotation process may be aided by utilizing various techniques for automatically or semiautomatically generating the annotations.

45. A method for retrieving relevant text subdivisions from a database where there are one or more annotations in structured form stored for and suitably connected to at least selected ones of said subdivisions, each of said annotations containing at least some words having a predetermined relationship selected by an annotator, the method comprising the steps of:
generating a search query in structured form having words with a selected relationship, matching the structured form search query with the stored annotations, and presenting text subdivisions connected to annotations matching the search query in both words and relationship which are found during said matching step. - View Dependent Claims (46)

47. A system for retrieving relevant text subdivisions from a database where there are one or more annotations in structured form stored for and suitably connected to at least selected ones of such subdivisions, each of said annotations containing at least some words having a predetermined relationship selected by an annotator, the system comprising:
means for generating a search query in structured form having words with a selected relationship, means for matching the structured form search query with the stored annotations, and means for presenting text subdivisions connected to annotations matching the search query in both word and relationship found during said matching step. - View Dependent Claims (48)
