Abstract

A patent document content construction method is described. The method includes the following steps. A domain-specific thesaurus including a plurality of domain-specific terms is constructed. A semantic/syntactic annotation is performed for a claim of a patent to identify domain-specific terms, stop words, general terms, and punctuation. Defined regular expression sets are used to classify the words in a claim to build a structural relation of the claim. The defined expression sets include Common, Claim, Component, Reference, Attribute, Functionality, Contain, and Spatial. The structural relation includes the domain-specific terms, the general terms, and the triple relations of the domain-specific terms in the claim.

Claims

1. A patent document content construction method, comprising the steps of:

establishing a domain-specific thesaurus containing a plurality of domain-specific terms that form a hierarchical structure;

performing annotation on a claim of the patent to identify domain-specific terms, stop words, general words, and punctuation in the claim; and

using the thesaurus to establish a structural relation for the claim, the structural relation including domain-specific terms, general terms, and triple relations of the domain-specific terms and the general terms.

2. The method of claim 1, further comprising the step of classifying domain-specific terms of the same class into one level in the hierarchical structure of the domain-specific thesaurus.

3. The method of claim 1, wherein the step of part-of-speech (POS) syntactic annotation is performed on the claim before the semantic/syntactic annotation.

4. The method of claim 1, further comprising the step of comparing a term appearing in the claim with the domain-specific terms in the domain-specific thesaurus to determine the content of the term in the claim in the step of performing the semantic/syntactic annotation.

5. The method of claim 1, wherein the stop words include “

a” and

“

the”

.

6. The method of claim 1, wherein the claim is an independent claim.

7. The method of claim 1, wherein the claim is a dependent claim and the method performs the step of semantic/syntactic annotation on the dependent claim and the associated independent claim and establishes the structural relation.

8. The method of claim 1, further comprising the step of using a structure graph to show the structural relation of the claim.

9. The method of claim 8, further comprising using a regular expression and the definitions of a plurality of tokens to determine the structure graph.

10. The method of claim 1, further comprising the step of using a regular expression to parse the claim.

11. The method of claim 10, wherein the regular expression includes identifying a component of the claim.

12. The method of claim 10, wherein the regular expression includes identifying a reference link between two components in the claim.

13. The method of claim 10, wherein the regular expression includes identifying attributes of a component in the claim.

14. The method of claim 10, wherein the regular expression includes identifying a functionality description of a component in the claim.

15. The method of claim 10, wherein the regular expression includes identifying whether a part-of relation exists between two components in the claim.

16. The method of claim 10, wherein the regular expression includes identifying whether a spatial relation exists between two components in the claim.

17. A patent document content construction method, comprising the steps of:

performing semantic/syntactic annotation on a claim of the patent to identify domain-specific terms, stop words, general words, and punctuation in the claim; and

using a domain-specific thesaurus to establish a structural relation for the claim, the structural relation including domain-specific terms, general terms, and triple relations of the domain-specific terms and the general terms.

18. The method of claim 17, wherein the domain-specific thesaurus contains a plurality of domain-specific terms in a particular domain, and the domain-specific terms form a hierarchical structure.

19. The method of claim 17, further comprising the step of comparing a term appearing in the claim with the domain-specific terms in the domain-specific thesaurus to determine the content of the term in the claim in the step of performing the semantic/syntactic annotation.

20. The method of claim 17, further comprising the step of using a structure graph to show the structural relation of the claim.
