Abstract

A configurable system brings Internet services, designed for PCs, to consumer electronics (CE) devices, and allows using external services such as Internet Services on CE devices. This reduces the need for input devices such as keyboards and mice, thereby making the configurable system suitable for CE devices. The configurable system relies on the structure of HTML/XML embedded in a Web page for information extraction by scrapping. Since cosmetic changes made to the Web site alter the embedded HTML/XML, the configurable system is updated whenever the Web site changes.

Claims

1. A method of providing services of an external network to a client device connected to the external network, comprising:

in a client device in a local network;

obtaining structure of a structured document from a server for accessing desired services in the external network corresponding to the structured document, wherein the structured document resides in the external network, wherein said structure of the structured document comprises rules for encoding documents in machine-readable form;

incorporating the obtained structure into a configuration file;

receiving the configuration file by the client device in the local network;

based on the obtained structure, performing a scraping process on the structured document to obtain information for providing desired services in the external network, wherein the scraping process is configured using the obtained structure in the configuration file;

providing the information for displaying on the client device;

providing a server connected to the client device; and

maintaining on the server manually created configuration files corresponding to certain Web pages in the external network.

2. The method of claim 1 wherein:

the external network comprises the Internet and the structured document comprises a Web page in a Web site in the external network providing services.

3. The method of claim 2 wherein:

said structure of the structured document comprises rules for encoding documents in machine-readable form; and

obtaining further includes obtaining the structure of machine-readable HTML/XML encoding embedded in the Web page for information extraction by scraping.

4. The method of claim 2 wherein a configuration file corresponding to each Web page includes rules for ascertaining structure of the Web page.

5. The method of claim 2 wherein scraping further includes hybrid scraping by performing scraping in the client device and providing configuration file updates to the client device from the server.

6. The method of claim 2 wherein the desired services is based on user activity.

7. The method of claim 2, wherein the scraping process is configurable to scrape different Web pages with different structures, based on respective Web page structures contained in corresponding configuration files.

8. The method of claim 2 further comprising updating the configuration file for the corresponding Web page as the Web page structure changes.

9. The method of claim 1 further comprising:

querying the server by the client device for configuration files; and

responding by the server by providing configuration file information.

10. The method of claim 9 wherein querying the server by the client device for configuration files further includes:

using the available configuration files to display to a user the corresponding services in the external network that can be used by the user.

11. The method of claim 10 further including:

receiving service selection by the user;

the client device retrieving the corresponding configuration file from the server for scraping; and

performing scraping by the client device using the obtained structure in the configuration file to interact with the corresponding Web page in the external network.

12. The method of claim 11 wherein the retrieved obtained structure in the configuration file includes one or more of:

the location of the selected service provider in the external network;

a description of the selected service;

the interface to various services provided by the service provider;

rules that instruct the client as to which fragments of HTML/XML in the Web page are to be extracted by scraping;

semantics of the extracted data;

display information;

words relevant to the service;

version number of the configuration file; and

preferred Web page information.

13. The method of claim 11 wherein scraping further includes scraping sufficient information to extract information about the selected service from the Web page.

14. The method of claim 9 further comprising:

checking a version of the configuration file stored in the client device against a version of a configuration file on the server in the external network; and

when a new configuration file is available, downloading the new configuration file from the server in the external network.

15. The method of claim 1, wherein the information includes attribute pairs obtained from content meta-data.
