Method For Information Retrieval
First Claim
1. A method of indexing documents for use with a search engine comprising:
- identifying the words contained in a document;
processing the words contained in the document in an adaptive language processing module so as to associate each word with a measure of confidence value, the measure of confidence value being associated with a particular ambiguity of the word;
storing each word and its measure of confidence value in a reverse index along with location information for the document.

Abstract
A method of retrieving documents using a search engine includes providing a reverse index including one or more keywords and a list of documents containing the one or more keywords, the reverse index further including a measure of confidence (MOC) value associated with the one or more keywords. One or more query terms are input into the search engine. The query terms are disambiguated and a MOC value is associated with each meaning of the disambiguated query term. A list of documents is retrieved containing the query terms wherein the documents are initially ranked based at least in part on the MOC values of the keywords and query terms. The list of documents may be re-ranked based at least in part on the semantic similarity of each document to the disambiguated query terms.

-
providing a reverse index including one or more keywords and a list of documents containing the one or more keywords, the reverse index further including a measure of confidence value associated with the one or more keywords; inputting one or more query terms into to the search engine; disambiguating the query terms by obtaining a measure of confidence value for each query term based at least in part on the meaning of each query term; retrieving a list of documents containing the one or more query terms, wherein the retrieved documents are initially ranked based at least in part on the measure of confidence value associated with the keyword contained in document and the measure of confidence value associated with each query term meaning; and re-ranking the list of documents at least in part based the semantic similarity of each document to the disambiguated query terms. - View Dependent Claims (24, 25, 26, 27)

31. A method of retrieving documents using a search engine comprising:
-
submitting a query to a search engine; presenting a user with a list of documents, the list including an exclusion tag associated with each document in the list; selecting one or more exclusion tags in the list to exclude one or more documents; determining a similarity measure for each document in the list based at least in part on the similarity of the document to those documents associated with a selected exclusion tag; and re-ranking the list of documents based on the determined similarity measure, wherein those documents most similar to the excluded documents are demoted or removed from the re-ranked list. - View Dependent Claims (33, 34)
