Scheme for constructing database for user system from structured documents using tags
First Claim
1. A data relay device, comprising:
- a document obtaining unit configured to obtain a structured document provided by a server device according to a document request received from a client device through a communication path, the structured document having a structure represented by tags in the structured document;
an extraction and storing unit configured to automatically extract at least one specific portion from the structured document by utilizing the tags representing the structure of the structured document according to prescribed extraction criteria specified in advance and indicating at least one specific tag that labels said at least one specific portion to be extracted, and store said at least one specific portion into a database specific to the client device such that said at least one specific portion stored in the database is subsequently accessible by the client device; and
a transfer unit configured to transfer the structured document obtained by the document obtaining unit to the client device, by adding an information to a part of the structured document from which said at least one specific portion is extracted, so as to indicate to a user that said at least one specific portion has been extracted from said part of the structured document.

Abstract
A scheme for constructing a database in a user system, which can automatically store those portions of the structured documents which contain important contents without exerting a burden on the user is disclosed. A structured document provided by a server device is obtained according to a document request made by the user system, where each structured document has a structure represented by tags in each structured document. Then, at least one important portion is automatically extracted from the structured document by utilizing the structure of the structured document according to prescribed extraction criteria specified in advance, and the extracted important portion is stored into the database, while the obtained structured document is transferred to the user system.

24. A computer usable medium having computer readable program codes embodied therein for causing a computer to function as a data relay device, the computer readable program codes include:
-
a first computer readable program code for causing said computer to obtain a structured document provided by a server device according to a document request received from a client device through a communication path, the structured document having a structure represented by tags in the structured document; a second computer readable program code for causing said computer to automatically extract at least one specific portion from the structured document by utilizing the tags representing the structure of the structured document according to prescribed extraction criteria specified in advance and indicating at least one specific tag that labels said at least one specific portion to be extracted, and store said at least one specific portion into a database specific to the client device such that said at least one specific portion stored in the database is subsequently accessible by the client device; and a third computer readable program code for causing said computer to transfer the structured document obtained by the first computer readable program code to the client device, by adding an information to a part of the structured document from which said at least one specific portion is extracted, so as to indicate to a user that said at least one specific portion has been extracted from said part of the structured document.
