Citation network analytics

1. A computer-implemented method for linking documents that refer to other documents through implicit linkages, the method comprising:

identifying a first document, the first document comprising an authoritative comment regarding a second document;

establishing an explicit linkage between the first document and the second document based upon the authoritative comment;

identifying one or more third documents based upon the existence of a citation relationship between the second document and each of the one or more third documents

detecting an implicit relationship between the first document and the one or more third documents by using common information between the second document and the one or more third documents;

generating an impact value for each of the one or more third documents by comparing the implicit relationship with the first document to the explicit relationship with the second document, the impact value being an indicator of the implicit relationship between the first document and each of the one or more third documents;

linking the first document to the one or more third documents based upon the impact value; and

presenting the one or more third documents in response to a query for the first document.

2. The computer-implemented method of claim 1 , wherein the generation of the impact value is based on metadata and semantic text analysis.

3. The computer-implemented method of claim 1 , wherein the impact value indicates a level of impact displayed to a user.

4. The computer-implemented method of claim 1 , further comprising: using the impact value for indicating a reference between the first document and the one or more third documents.

5. The computer-implemented method of claim 1 , wherein the impact value relates to a visual effect for displaying a reference between the first document and the one or more third documents.

6. The computer-implemented method of claim 1 , further comprising: excluding a fourth document that cites the second document, the fourth document sharing different information other than the common information.

7. The computer-implemented method of claim 1 , further comprising: identifying the first document in response to an event relating to one or more of a new publication, case release, journal retraction, and legislation.

8. The computer-implemented method of claim 1 , further comprising: updating the linking when document changes occur.

9. The computer-implemented method of claim 1 , further comprising: including in the linkage additional documents citing or being cited by the one or more third documents.

10. A computer-based system comprising processor, memory, and machine readable code stored in memory and executable by processor for linking documents that refer to other documents through implicit linkages, the system is configured to:

identify a first document, the first document comprising an authoritative comment regarding a second document;

establish an explicit linkage between the first document and the second document based upon the authoritative comment;

identify one or more third documents, based upon the existence of a citation relationship between the second document and each of the one or more third documents;

detect an implicit relationship between the first document and the one or more third documents by using common information between the second document and the one or more third documents;

generate an impact value for each of the one or more third documents by comparing the implicit relationship with the first document to the explicit relationship with the second document, the impact value being an indicator of the implicit relationship between the first document and each of the one or more third documents;

link the first document to the one or more third documents based upon the impact value; and

present the one or more third documents in response to a query for the first document.

11. The system of claim 10 , wherein the impact value is indicative to an implicit relationship between the first document and the one or more third documents and is displayed to a user.

12. The system of claim 10 , wherein the system is updated when document changes occur.

13. Non-transitory computer readable media comprising program code stored thereon for execution by a programmable processor to perform a method for linking documents that refer to other documents through implicit linkages, the computer readable media comprising:

program code for identifying a first document, the first document comprising an authoritative comment regarding a second document;

program code for establishing an explicit linkage between the first document and the second document based upon the authoritative comment;

program code for identifying one or more third documents based upon the existence of a citation relationship between the second document and each of the one or more third documents;

program code for detecting an implicit relationship between the first document and the one or more third documents by using common information between the second document and the one or more third documents;

program code for generating an impact value for each of the one or more third documents by comparing the implicit relationship with the first document to the explicit relationship with the second document, the impact value being an indicator of the implicit relationship between the first document and each of the one or more third documents;

program code for linking the first document to the one or more third documents based upon the impact value; and

program code for presenting the one or more third documents in response to a query for the first document.
