Abstract

A web interaction system which enables a mobile telephone to interact automatically with web resources, in which the web interaction system comprises a query engine which operates on XML format data, translated from data obtained from a web site, the query engine parsing the XML into SAX events which are then queried by the query engine. Conventional query engines parse XML into a data object model (DOM) tree and not SAX events; DOM trees can however occupy significant memory space. SAX events on the other hand can be queried as parsing progresses (i.e. no need to wait for an entire DOM tree to be constructed before queries can be first performed). Not needing to wait for an entire web document to download is a major advantage since this would otherwise be a major bottleneck.

Claims

1. A web interaction system which enables a mobile telephone to interact with web resources, in which the web interaction system comprises a query engine which operates on XML format data obtained from content data extracted from a web site, the query engine parsing the XML format data into SAX events which are then queried by the query engine.

2. The system of claim 1 in which querying the SAX events is achieved using an object oriented XML query language with an event stream based engine.

3. The system of claim 1 in which the XML format data which the query engine operates on is obtained, either directly or indirectly via a translation engine, by an automated agent from content data relevant to goods or services to be purchased using the mobile telephone.

4. The system of claim 3 in which the web site provides the content data in XML, HTML or Javascript format.

5. The system of claim 4 in which the web site provides content data in non-XML format data, which is translated into valid XML using a translation engine by the web interaction system.

6. The system of claim 5 in which the translation engine can fully define the nesting semantics needed for efficient and valid XML.

7. The system of claim 1 in which the web interaction system uses an extensible plug-in framework which allows plug-in components to be readily added to the framework.

8. The system of claim 7 in which the plug-ins cover different parsers, support for different protocols or different query languages.

9. The system of claim 1 which uses business logic defined by a mobile telephone operator to prioritise or filter search results according to predefined rules.

10. The system of claim 1 in which the system automatically interrogates web based resources from multiple suppliers to allow a user of the mobile telephone to compare similar goods or services from different suppliers without those suppliers needing to provide wireless protocol specific data.

11. The system of claim 1 which automates user defined processes, enabling the user to delegate tasks to the system without the need for continued real time connection to the Internet.

12. The system of claim 1 which can be modified by user defined preferences or profiles.

13. The system of claim 1 which can supply data records defining the details of the process used by customers to look for goods or services to purchase.

14. A method of enabling a mobile telephone to interact with web resources, in which the method comprises the steps of:

(a) extracting content data from a web site according to an instruction sent from the mobile telephone;

(b) obtaining XML format data from the content data;

(c) parsing the XML format data into SAX events;

(d) querying the SAX events using a query engine to generate query results;

(e) providing a response to the instruction sent from the mobile telephone using the query result.

15. The method of claim 14 in which querying the SAX events is achieved using an object oriented XML query language and an event stream query engine.

16. The method of claim 14 in which the XML format data is obtained, either directly or indirectly via a translation engine, by an automated agent from content data relevant to goods or services to be purchased using the mobile telephone.

17. The method of claim 16 in which the web site provides the content data in XML, HTML or Javascript format.

18. The method of claim 14 in which the web site provides content data in non-XML format data, which is translated into valid XML using a translation engine.

19. The method of claim 18 in which the translation engine can fully define the nesting semantics needed for efficient and valid XML.
