Abstract

The present invention relates to a computer matching system used by a plurality of users and the method therefor, said system comprising a database; an offer creation program means for creating an entity for an offer input by each user in the database and storing said offer therein; and a search engine for comparing and matching a requirement input by a user with other users'"'"' offers stored in the database and returning matching results to said user. Advantageously, said requirement includes multiple elements as search criteria, each of said elements is assigned a weight of importance thereby each matching result has a search score indicating satisfaction level of said user, said search engine further perform ordering and ranking of said matching results according to the respective search scores thereof, and only the matching results have search scores above a predetermined satisfaction level are returned to said user. Said multi-element confidence matching system can automatically provide the user or trader with the information he is interested in without the intervention of the trader, and give the user the maximum amount of information about offers which may meet their requirement, so as to give the trader the ability to not just see offers which exactly match their criteria, but ones which come close or can fulfill part of, or more than, their needs, thereby the trader may conduct the search efficiently

Claims

1. A computer trade matching system useable by a plurality of users, said system comprising:

an offer database to store offers input to said system by at least one of said users;

offer creation program means for creating an entity for an offer input by each user in said offer database and associating each of said offers with one of supply and demand and storing said offers in said offer database;

requirement inputting program means for receiving as search criteria, via a user interface, a user requirement that includes multiple elements, each element being assigned a weight of importance, and for setting each said user requirement to one of supply and demand; and

a search engine to receive requirements from said requirement inputting programs means and to compare and match said user requirement with other users'"'"' offers stored in said offer database, and to return matching results to said user, wherein each matching result has a search score indicating satisfaction level of said user;

wherein comparing is performed by matching a demand requirement with supply offers, and by matching a supply requirement with demand offers.

2. The computer trade matching system of claim 1, wherein an input said user requirement is also processed as an offer by said offer creation program means such that said requirement is stored in said offer database.

3. The computer trade matching system of claim 2, wherein each offer and requirement includes at least one item selected from a group consisting of (a) demand, (b) supply, (c) name of goods, (d) amount of goods, and (e) price of goods.

4. The computer trade matching system of claim 2, wherein search queries in said search engine remain active after a user has submitted a requirement.

5. The computer trade matching system of claim 1, wherein said search engine further carries out ordering and ranking of said matching results according to respective search scores thereof.

6. The computer trade matching system of claim 5, wherein only matching results having search scores exceeding a predetermined satisfaction level are returned to said user.

7. The computer trade matching system of claim 1, wherein said user interface to said matching system is via the Internet.

8. The computer trade matching system of claim 1, wherein only match results having search scores exceeding a predetermined satisfaction level are returned to said user.

9. The computer trade matching system of claim 1, wherein each offer and requirement includes at least one item selected from a group consisting of (a) demand, (b) supply, (c) name of goods, (d) amount of goods, and (e) price of goods.

10. The computer trade matching system of claim 1, wherein search queries in said search engine remain active after a user has submitted a requirement.

11. A computer trade method for matching a requirement of a user with offers from other users, said method comprising the following steps:

(a) providing an offer database to store offers input by users;

(b) creating an entity for an offer input by each user in said offer database, associating each of said offers with one of supply and demand, and storing said offers in said offer database;

(c) receiving a requirement input by a user via a user interface and setting each requirement to one of supply and demand, said requirement including as criteria multiple elements, each of said elements being assigned a weight of importance such that each matching result has a search score indicating satisfaction level of said user;

(d) comparing and matching said user input requirement with other users'"'"' offers stored in said offer database, wherein said comparing and matching is carried out by matching a demand requirement with supply offers, and by matching a supply requirement with demand offers; and

(e) returning matching results from step (d) to said user.

12. The computer trade matching method of claim 11, wherein step (d) further includes ordering and ranking said matching results according to respective search scores thereof.

13. The computer trade matching method of claim 12, wherein at method step (e) only matching results having search scores above a predetermined satisfaction level are returned to said user.

14. The computer trade matching method of claim 13, wherein said requirement is further processed as an offer in step (b) such that said requirement is stored in said offer database.

15. The computer trade matching method of claim 12, wherein said requirement is further processed as an offer in step (b) such that said requirement is stored in said offer database.

16. The computer trade matching system claim 11, wherein only matching results having search scores exceeding a predetermined satisfaction level are returned to said user.

17. The computer trade matching method of claim 11, wherein said requirement is also processed as an offer at step (b) such that said requirement is stored in said offer database.

18. The computer trade matching method of claim 17, wherein said requirement includes multiple elements as search criteria, each of set elements being assigned a weight of importance such that each matching result has a search score indicating satisfaction level of said user, and wherein method step (d) further includes ordering and ranking said matching results according to respective search scores thereof.

19. The computer trade matching system of claim 17, wherein each offer and requirement includes at least one item selected from a group consisting of (a) demand, (b) supply, (c) name of goods, (d) amount of goods, and (e) price of goods.

20. The computer trade matching method of claim 17, wherein search queries in said search engine remain active after a user has submitted a requirement.

21. The computer trade matching system of claim 11, wherein each offer and requirement includes at least one item selected from a group consisting of (a) demand, (b) supply, (c) name of goods, (d) amount of goods, and (e) price of goods.

22. The computer trade matching method of claim 11, wherein search queries in said search engine remain active after a user has submitted a requirement.
