Dynamic generation of contextual links in hypertext documents
DCFirst Claim
1. A computer-implemented method of dynamically generating hypertext links from a source document to at least one document other than the source document, comprising:
- receiving a user selected portion of the source document;
selecting a plurality of terms from the user selected portion; and
for at least one selected term, automatically creating at least one hypertext link to a document, other than the source document, relevant to the term.

Abstract
A system, method, and software product create contextual hypertext links relevant to a user selected portion of a source document. The contextual links enable the user to dynamically associate the source document with any available target document, regardless of whether links where created between the source document and the target document when the source document was created. The method includes selecting terms relevant to the user selected portion by linguistic analysis which selects the most frequently occurring terms. From the selected terms target documents relevant to the selected terms are identified. The target documents are selected by identifying topics that are associated with, or described by, the selected terms. Contextual links are created between the selected terms and target documents associated with the identified topics using the URLs for the documents in the contextual links. The system includes a knowledge base of topics, including hierarchical relations between topics, and associations of topics and terms. A document collection includes documents and references to documents, and URL or other addressing information for the documents. A tagging module receives a user selected portion and selects terms to be used for the contextual links. A presentation module identifies the topics in the knowledge base associated with the selected terms, the documents associated with each topic, and creates the hypertext links between the terms and the documents.

8. A computer-implemented system for dynamically generating content dependent hypertext links in a source document to link from the source document to at least one other document other than the source document, the system comprising:
-
a knowledge base storing a plurality of topics, each topic associated with at least one term semantically related to the topic, each topic further associated with the at least one document that is about the topic; a tagging module communicatively coupled to the knowledge base, that receives a user selected portion of the source document, and determines topics in the knowledge base associated with the selected terms relevant to the user selected portion; and a presentation module communicatively coupled to the knowledge base, that receives the user selected portion of the source document and the selected terms determined by the tagging module, and for each selected term, determines the topics associated with the term, and the at least one document associated with each topic, creates hypertext links to the at least one document associated with the topics, and associates the hypertext links with the source document. - View Dependent Claims (9)

10. A computer-implemented method of dynamically generating hypertext links in a source document, comprising:
-
receiving a user selected portion of the source document; selecting from the user selected portion a plurality of the most frequently occurring terms; for each selected term; determining at least one topic of which the selected term is descriptive; for each topic, determining at least one document other than the source document associated with the topic; and creating a hypertext link from the selected term to each document other than the source document associated with each of the topics of which the selected term is descriptive.

-
receiving a user selected portion of the source document; and for at least one term in the user selected portion, automatically creating at least one hypertext link to a document, other than the source document, relevant to the term. - View Dependent Claims (12, 13)
