Abstract

A method of providing information to a user via a printed substrate, said substrate comprising user information and coded data indicative of a region identity associated with the substrate and of a plurality of locations on the substrate, said method comprising the steps of: receiving, in a computer system, interaction data indicative of the region identity and at least one position of a sensing device relative to the substrate, the sensing device generating the interaction data, when operatively positioned or moved relative to the substrate, by reading at least some of the coded data; identifying and retrieving at least part of a page description corresponding to the printed substrate using the region identity; generating a query expression comprising one or more search terms, at least one of said search terms being identified using the page description and the at least one position of the sensing device; forming a request using the query expression; and sending the request, or a results resource including search results obtained using the request, to the user.

Claims

1. A method of providing information to a user via a printed substrate, said substrate comprising user information and coded data indicative of a region identity associated with the substrate and of a plurality of locations on the substrate, said method comprising the steps of:

receiving, in a computer system, interaction data indicative of the region identity and at least one position of a sensing device relative to the substrate, the sensing device generating the interaction data, when operatively positioned or moved relative to the substrate, by reading at least some of the coded data;

identifying and retrieving at least part of a page description corresponding to the printed substrate using the region identity;

generating a query expression comprising one or more search terms, at least one of said search terms being identified using the page description and the at least one position of the sensing device;

forming a request using the query expression; and

sending the request, or a results resource including search results obtained using the request, to the user.

2. The method of claim 1, wherein the request is a request URI derived from the query expression.

3. The method of claim 2, wherein the request URI is sent to the user'"'"'s web terminal, thereby enabling the user'"'"'s web terminal to retrieve a corresponding resource via the internet.

4. The method of claim 1, wherein the at least one search term is associated, in the page description, with a zone of the substrate containing the position of the sensing device.

5. The method of claim 4, wherein the at least one search term is a keyword extracted from text in the zone.

6. The method of claim 5, wherein said keyword comprises a plurality associated words, said plurality of associated words being identified from at least one word in the zone.

7. The method of claim 6, wherein the page description comprises a lexicon for identifying said plurality of associated words from the at least one word and at least one adjacent word.

8. The method of claim 4, wherein the at least one search term is a primary search term and at least one of the other search terms of the query expression is a context search term, said context search term being derived from a word, phrase, line, sentence, paragraph, section, article, document or region containing the zone.

9. The method of claim 8, wherein said context search term is contained in or associated with a word, phrase, line, sentence, paragraph, section, article, document or region containing the zone.

10. The method of claim 8, wherein the search results all contain the primary search term, and are ranked according to whether they contain the context search term.

11. The method of claim 8, wherein the at least one primary search term is a keyword and the at least one context search term is derived by at least partially determining a meaning of said keyword.

12. The method of claim 11, wherein the meaning is at least partially determined using a method selected from the group comprising:

identifying a part of speech for said keyword;

identifying a supersense of said keyword; and

identifying a concept corresponding to said keyword in an ontology.

13. The method of claim 1, wherein at least one of said search terms identifies a concept, a person, an organization, a place, a product, a publication, a weather condition, a geographic location, a date, a time of day, a day of the week, a current user location, a user home location, a user demographic indicator, a user preference, a search history, a click-through history, a user interest or a user language.

14. The method of claim 1, wherein at least one of said search terms is derived from a resource description, a subject description, a user description or an environment description.

15. The method of claim 1, wherein the query expression is generated by combining the search terms using operators selected from the group comprising:

Boolean operators, proximity constraint operators and occurrence constraint operators.

16. The method of claim 1, wherein the results resource is derived, at least partially, from the request using at least one of:

a concordance;

a semantic concordance;

a database of search terms associated with advertisements; and

a search engine.

17. The method of claim 16, wherein the search engine is selected using said page description.

18. The method of claim 1, wherein the substrate is selected from the group comprising:

a printed document, a printed form, a page of a printed publication, a package for a product item, a label for a product item and a surface of a product item.

19. The method of claim 1, wherein the resource is a webpage.

20. A computer system for providing information to a user via a printed substrate, said substrate comprising user information and coded data indicative of a region identity associated with the substrate and of a plurality of locations on the substrate, said computer system being configured for:

receiving, in a computer system, interaction data indicative of the region identity and at least one position of a sensing device relative to the substrate, the sensing device generating the interaction data, when operatively positioned or moved relative to the substrate, by reading at least some of the coded data;

identifying and retrieving at least part of a page description corresponding to the printed substrate using the region identity;

generating a query expression comprising one or more search terms, at least one of said search terms being identified using the page description and the at least one position of the sensing device;

forming a request using the query expression; and

sending the request, or a results resource including search results obtained using the request, to the user.
