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.
