Abstract

A method and apparatus for extracting terms associated with a displayed text. The method and apparatus receive a location indication from a user, read the text, determine the seed location within the text relating to the indicated location, determine the text surrounding the seed location in a determined scope, match terms from the determined text scope with a concept collection, choose the most dominant concepts which were matched, and extract terms that are associated with the dominant concepts.

Claims

1. A method for determining an at least one output term associated with a text displayed on a display device associated with a computing platform, the method comprising the steps of:

receiving an indication to a location on the display device;

identifying a seed location within the text displayed on the display device from the location indication;

determining a scope of the text which includes the seed location;

identifying an at least one match between at least one term from the scope of the text and an at least one concept from a concept collection;

identifying an at least one dominant concept for which an at least one match between the at least one concept and the at least one term was identified; and

extracting the at least one output term as an at least one term associated with the at least one dominant concept.

2. The method of claim 1 further comprising a step of obtaining the text displayed on the display device.

3. The method of claim 1 further comprising a step of selecting the concept collection from a multiplicity of concept collections.

4. The method of claim 1 further comprising a step of determining a language of the text.

5. The method of claim 1 further comprising a step of creating a query from the at least one output term.

6. The method of claim 1 further comprising a step of stemming an at least one word from the text.

7. The method of claim 1 farther comprising a step of using the at least one output term.

8. The method of claim 7 wherein the at least one output term is used as a query for a search engine.

9. The method of claim 1 wherein the concept collection is a concept hierarchy.

10. The method of claim 1 wherein the at least one dominant concept is identified using clustering.

11. The method of claim 1 wherein each of the at least one output term comprises a weight indication.

12. The method of claim 11 wherein the weight indication is associated with a distance between the at least one output term and the seed location.

13. The method of claim 1 wherein the at least one output term is the at least one term matched with the at least one dominant concept.

14. The method of claim 1 wherein the scope of the text is the text displayed on the display device.

15. The method of claim 1 wherein the scope of the text is determined using topic segmentation.

16. The method of claim 1 wherein the scope of the text is determined using grammatical segmentation.

17. The method of claim 1 when used for determining an at least one advertisement to be presented to a user.

18. The method of claim 1 when used for retrieving information from enterprise data.

19. An apparatus for determining an at least one output term from a text displayed on a display device, the display device associated with a computing platform, the apparatus comprising:

an input device for receiving an indication for a location on the display device;

a seed location identification component for identifying a seed location within the text displayed on the display device from the location indication;

a text scope determination component for determining an at least one part of the text displayed on the display device, the part includes the seed location;

a term-concept matching component for matching an at least one term from the scope of the text with an at least one concept from a concept collection;

a dominant concept identification component for identifying an at least one dominant concept for which an at least one match between the at least one concept and the at least one term was identified; and

a term extraction component for extracting an at least one output term associated with the at least one dominant concept.

20. The apparatus of claim 19 further comprising a language determination component for determining the language in which the text is written.

21. The apparatus of claim 19 further comprising a concept collection selection component for selecting the concept collection relevant to the text.

22. The apparatus of claim 19 further comprising a text obtaining component for obtaining the text displayed on the display device.

23. A computer readable storage medium containing a set of instructions for a general purpose computer, the set of instructions comprising:

receiving an indication to a location on the display device associated with a computing platform, the display device displaying text;

identifying a seed location within the text displayed in the display device from the location indication;

determining a scope of the text which includes the seed location;

identifying an at least one match between at least one term from the scope of the text and an at least one concept from a concept collection;

identifying an at least one dominant concept for which an at least one match between the at least one concept and the at least one term was identified; and

extracting an at least one output term as the at least one term associated with the at least one dominant concept.
