Abstract: A status messaging service is used as an online channel for indirect messaging in a word-of-mouth marketing campaign. A user of a web service is prompted to endorse the web service to the user's friends or other connections by submitting a status message to one or more status messaging services to which the user belongs. The status message contains an endorsement of the web service and may further contain a link to a personal invitation page for the web service. By submitting the status message to a status messaging service, the endorsement contained therein is then communicated to the user's connections in the status messaging service.

Abstract: An intuitive, immersive, movement-based interface and system provides for navigating through large collections of multidimensional information. The interface allows users to navigate through large document collections by maintaining a constant density of visual information presented on a display device to the user at any given moment of time. The document collection is organized in an immersive information space, containing various levels of topics and related documents. At each level within the immersive information space contextual information is presented to the user. The contextual information consists of a semantic scale and a pathway to the information they are viewing. An information structure represents the immersive information space of documents. The information structure consists of a collection of documents, and a graph of topics that describe the relationships between the documents.

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.
