Abstract

A method and system for real-time online search processing over inter-connected computer networks of search requests received from wireless handheld clients, in which a server communicates with a wireless handheld client using an XML-like protocol, and an offline database information is maintained for a plurality of vendor sites from the inter-connected computer networks. The information includes URLs, search form URLS, description of domains, and vendor descriptions which include generalized rules about how product information is organized on each of the vendor sites. A product keyword request from the wireless handheld device client is processed using the information maintained in the offline database. Real-time price and product information are extracted from identified ones of the plurality of vendor sites in a native language of the site; and the extracted price and product information are communicated to the user through the server.

Claims

1. A method for real-time online search processing over inter-connected computer networks of shopping requests received from a wireless handheld client in a received native language, comprising the steps of

a. communicating with the wireless handheld client through a remote server using XML;

b. maintaining in an offline database information for a plurality of vendor sites each having a native language over inter-connected computer networks, wherein the plurality of vendor sites include vendor sites in different native languages, and the maintained information includes URL'"'"'s, search form URL'"'"'s, description of domains, and vendor descriptions and, for each of the plurality of vendor sites, information in the native language of that vendor site, wherein the vendor descriptions include generalized rules about how product information is organized on each of the plurality of vendor sites;

c. processing a product keyword request, received from the wireless handheld device client in the received native language through the remote server, including using the vendor descriptions to identify ones of the plurality of vendor sites which may have information responsive to and in the received native language of the product keyword request, and using the search form URL'"'"'s;

d. extracting real-time price and product information from the identified ones of the plurality of vendor sites, wherein the extracted price and product information are in the received native language; and

e. communicating the extracted real-time price and product information to the wireless handheld device client through the remote server.

2. The method of claim 1, wherein the step of processing a product keyword request further comprises the step of receiving from the wireless handheld device client a single country designation;

and further wherein the extracting step includes the steps of

i) posting a request using the processed parameters to at least one of the plurality of vendors online, in real-time; and

ii) retrieving data related to the price and product information from search results obtained in response to the posting step;
