Abstract

A method for processing electronic document and its corresponding device, a method for browsing electronic document and its corresponding browser, as well as a method for searching electronic document and its corresponding searching system are disclosed in the present invention. The method comprises at least the following steps of: generating one or more query according to the content of said document when an author is composing the electronic document; and correspondingly storing information about said one or more query with said electronic document. Wherein the query comprises keywords, keyword string or questions, and the query has passed the verification in order to ensure its reliability.

Claims

1. An electronic document browsing method, characterized in that it comprises steps of:

reading query information correspondingly stored with the electronic document, wherein said query including keywords, keyword string or questions;

presenting user with one or more query contained in query information; and

representing the content of said electronic document to said user when user confirms said query.

2. The electronic document browsing method according to claim 1, characterized in that said step of representing the content of said electronic document to the user comprises:

inputting one or more query that the user wants to execute, wherein said query including keywords, keyword string or questions;

selecting a query, in which the keywords, keyword string and questions are closely related to those input by the user; and

representing the most related query to the user.

11. An article of manufacture comprising a computer usable medium having computer readable program code means embodied therein for causing electronic document browsing, the computer readable program code means in said article of manufacture comprising computer readable program code means for causing a computer to effect the steps of claim 1.

3. An electronic document browser, characterized in that it comprises:

an electronic document browsing unit for browsing the content of the electronic document;

a query information reading unit for reading one or more query information correspondingly stored with the electronic document, wherein said query contains keywords, keyword string or questions; and

a query representing unit for representing the user with one or more query in query information read by the query information reading unit.

4. The electronic document browser according to claim 3, characterized in that it further comprises:

a query selection unit for selecting the query same with or closely related to the query input by user from one or more query contained in the query information; and

a query representing unit being further used to represent the user with the same or closely related query or queries.

14. A computer program product comprising a computer usable medium having computer readable program code means embodied therein for causing functions of an electronic document browser system, the computer readable program code means in said computer program product comprising computer readable program code means for causing a computer to effect the functions of claim 3.

5. An electronic document retrieving method, characterized in that it comprises the steps of:

extracting one or more query information correspondingly stored with the electronic document, wherein each of the query information containing keywords, keyword string or questions of one or more corresponding queries;

generating indices for the extracted multiple query information;

in responsive to the user'"'"'s queries, searching one or more queries, which is same or closely related to the user'"'"'s query input, from the query indices;

representing the user with said same or closely related queries; and

providing the user with the electronic document or a link to said electronic document according to the user'"'"'s selected query.

6. The electronic document retrieving method according to claim 5, characterized in that said step of searching one or more query same with or closely related to the query input by the user further comprises:

calculating relevance degree between the query input by the user and each query in the query indices;

selecting the query with the largest relevance degree or whose relevance degree is larger than a given value.

7. The electronic document retrieving method according to claim 5, characterized in that said step of representing the user with one or more query same with or closely related to the query input by user further comprises:

verifying the represented query through operations of evaluating and/or modifying, and giving a corresponding feedback information; and

updating the query information according to said feedback information.

12. An article of manufacture comprising a computer usable medium having computer readable program code means embodied therein for causing electronic document retrieving, the computer readable program code means in said article of manufacture comprising computer readable program code means for causing a computer to effect the steps of claim 5.

8. An electronic document retrieving system, characterized in that it comprises:

a query information extracting means for extracting query information correspondingly stored with said electronic document, wherein each of said query information containing keywords, keyword string or questions of one or more queries;

a query indexing means for generating indices of the queries in said extracted query information;

a query index storing means for storing query indices produced by the query indexing means;

a query searching means for searching one or more query, which are same with or closely related to the user'"'"'s query input, from the query indices stored in the query index storing means;

a query presenting means for presenting the user with one or more queries, which are same with or closely related to user'"'"'s query, searched by query searching means; and

an electronic document providing means for providing the user with the electronic document or a link to said electronic document according to the user'"'"'s selected query.

9. The electronic document retrieving system according to claim 8, characterized in that it further comprises:

a similarity calculating means for calculating the relevance degree between two word strings;

wherein, said query searching means, utilizing said similarity calculating means, calculating the relevance degree between the query input by the user and the queries in query indices, and selecting one query with the largest relevance degree or the ones whose relevance degree is larger than a given value.

10. The electronic document retrieving system according to claim 8 characterized in that it further comprises:

a query feedback means for verifying the represented query through operations of evaluating, modifying, then returning a feedback information correspondingly and updating the corresponding query information.

13. A computer program product comprising a computer usable medium having computer readable program code means embodied therein for causing functions of an electronic document retrieving system, the computer readable program code means in said computer program product comprising computer readable program code means for causing a computer to effect the functions of claim 8.
