Abstract: Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative browsing session. One or more controllers connect the users or collaborators in a session in the server system. This is realized by establishing a so-called “shared Web-top”, i.e., a work space, in which different in-document applications can be run and can be interactively, collaboratively shared by a plurality of users. Specifically, this is realized in one embodiment by employing event handlers in the WEB documents that are activated whenever there is a change in the values of prescribed properties of a document. The event handlers notify a so-called surrogate of the changes in the prescribed properties of the document, i.e., that values in elements of a form have changed, and transmit the detected changes to surrogates of other users, i.e., at least one other collaborator, via a communication channel.

Abstract: An arrangement for realizing asymmetric collaboration utilizes a “shared Web-top”, i.e., a work space, in which different in-document applications can run and be shared. Specifically, in one embodiment of the invention employed in asymmetric collaboration, documents to be collaborated on at different users' terminals are logically identical but structurally different. Indeed, one of the collaborators, for example, a customer service agent, may have access to information that should not be made available to others of the collaborators. This asymmetric collaboration is realized by assigning a unique logical name to each information entity. Then, changes in the entity captured by some detection technique, for example, the use of document polling or event handlers, are propagated along with the name of the entity to the collaborators, where they are processed only if the relevant named entity exists.

Abstract: In a communications arrangement, a computer user accesses a server system to seek customer service over the World Wide Web (WWW). The server system assigns a customer service agent (CSA) to communicate with the user to realize the customer service. In a customer service session, the user and CSA may collaboratively browse hypertext markup language (HTML) documents at different uniform resource locators (URLs) to obtain relevant information. However, in accordance with the invention, the version of each document presented to the user may be different from that presented to the CSA. In particular, the CSA version contains proprietary information which is excluded from the user version.

Abstract: Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative browsing session. The users or collaborators in a session are connected by one or more controllers in the server system. When a collaborator creates or joins a session, mobile code is transmitted from the system to the collaborator's computer to create a surrogate thereon, which monitors the collaborator's interaction with a web browser on the computer. The controllers communicate with all the surrogates of the collaborators to coordinate the collaborative browsing effort. When one of the surrogates detects a change by a collaborator of a uniform resource locator (URL), the new URL is communicated through the controllers to the surrogates of all other collaborators in the session. As such, the collaborators are able to move from one URL to another to browse information in a synchronous manner.

Abstract: A method and system for visualizing relatively large amounts of data in a limited display space includes segmenting the data, mapping each segment to a node within the display space based on a specified nodal layout, texture mapping each graphical display of each segment of data to its node, and displaying the data in each node of the display space as mapped. This visualization scheme enables a user to map a relation to a specification of an N-dimensional display, by designating how attributes are to be used to get a desired segmentation, layout and presentation and enables a user to explore the data with various exploring features including real time continuous scaling.
