Abstract
The present inventor devised, among other things, information retrieval systems, methods, software, and related interfaces that help users assess and if necessary bolster the quality of their manual selections from search results. One exemplary system receives a set of documents selected from search results for an input query, identifies key subjects in the selected documents, and outputs a graphic, such as a pie chart, that shows not only how well these selected documents relate to the query, but also whether there are gaps in the topical scope of the selected documents related to the input query.
Claims6
An information retrieval system comprising:
- a server computer interfacing with a database;
- an access device interfacing with the server;
- a user interface module running on the server and configured to receive a query from the access device, query the database, and return a set of search results to the access device based on the received query;
- a user-operable selection feature integrated into the user interface module and configured to send a user-selected subset of the search results to the server;
- and
- a coverage analysis module interfacing with the server and the access device and configured to extract and analyze key subjects from documents in the database corresponding to the subset of search results;
- wherein the coverage analysis module is configured to display a topical map via the access device, the topical map showing the extent to which the documents cover the topic space defined by the query.
A computer implemented method of providing coverage analysis of user selected information, comprising:
- receiving a query in a database;
- receiving a user-selected portion of search results in the database based on the received query;
- extracting and analyzing key subjects from documents in the database corresponding to the user-selected portion of search results;
- and
- displaying, on an output device, a topical map showing the extent to which the documents cover the topic space defined by the query.
An information retrieval system comprising:
- a server computer interfacing with a database;
- an access device interfacing with the server;
- a subject guide module interfacing with server and the database to build a master subject guide for the database, wherein the master subject guide includes a data structure that is logically associated with a document identifier for each document in the database;
- a user interface module running on the server and configured to receive a query from the access device, query the database, and return a set of search results to the access device based on the received query;
- a user-operable selection feature integrated into the user interface module and configured to send a user-selected subset of the search results to the server;
- and
- a coverage analysis module interfacing with the server, the access device and the subject guide module, the coverage analysis module being configured to extract and analyze key subjects from documents in the database corresponding to the subset of search results and compare the key subjects to the master subject guide;
- wherein the coverage analysis module is configured to display a topical map via the access device, the topical map showing the extent to which the documents cover the topic space defined by the query, as determined by the master subject guide.
