An information retrieval system includes an enhanced document vector module to generate enhanced document vectors representative of documents in a collection. The enhanced document vectors include text- and non-text components. The non-text components may include the location, in-links, and/ or out-links in hypertext documents and attributes of the documents, e.g., size , create-date, and response-time. A processor uses the enhanced document vecto rs to perform an information retrieval operation, such as a clustering or classification operation.
