In its current implementation, the World-Wide Web lacks much of the explicit structure and strong typing found in many closed hypertext systems.While this property probably relates to the explosive acceptance of the Web, it further complicates the already difficult problem of identifying usable structures and aggregates in large hypertext collections.These reduced structures, or localities, form the basis for simplifying visualizations of and navigation through complex hypertext systems.Much of the previous research into identifying aggregates utilize graph theoretic algorithms based upon structural topology, i.e., the linkages between items.Other research has focused on content analysis to form document collections.This paper presents our exploration into techniques that utilize both the topology and textual similarity between items as well as usage data collected by servers and page meta-information lke title and size.Linear equations and spreading activation models are employed to arrange Web pages based upon functional categories, node types, and relevancy.

We present a new focus+context (fisheye) technique for visualizing and manipulating large hierarchies. Our technique assigns more display space to a portion of the hierarchy while still embedding it in the context of the entire hierarchy. The essence of this scheme is to lay out the hierarchy in a uniform way on a hyperbolic plane and map this plane onto a circular display region. This supports a smooth blending between focus and context, as well as continuous redirection of the focus. We have developed effective procedures for manipulating the focus using pointer clicks as well as interactive dragging, and for smoothly animating transitions across such manipulation. A laboratory experiment comparing the hyperbolic browser with a conventional hierarchy browser was conducted.

This paper describes Butterfly, an Information Visualizer application for accessing DIALOG'S Science Citation databases across the Internet.Network information often involves slow access that conflicts with the use of highly-interactive information visualization.Butterfly addresses this problem, integrating search, browsing, and access management via four techniques: 1) visualization supports the assimilation of retrieved information and integrates search and browsing activity, 2) automatically-created "link-generating" queries assemble bibliographic records that contain reference information into citation graphs, 3) asynchronous query processes explore the resulting graphs for the user, and 4) process controllers allow the user to manage these processes.We use our positive experience with the Butterfly implementation to propose a general information access approach, called Organic User Inteifacesfor Infomiation Access, in which a virtual landscape grows under user control as information is accessed automatically.

We present a new visualization, called the Table Lens, for visualizing and making sense of large tables. The visualization uses a focus+context (fisheye) technique that works effectively on tabular information because it allows display of crucial label information and multiple distal focal areas. In addition, a graphical mapping scheme for depicting table contents has been developed for the most widespread kind of tables, the cases-by-variables table. The Table Lens fuses symbolic and graphical representations into a single coherent view that can be fluidly adjusted by the user. This fusion and interactivity enables an extremely rich and natural style of direct manipulation exploratory data analysis.

Although the document imaging industry has taken off in the last few years, document image filing for the individual information worker is still not widespread or effective. In this paper, we focus on building an electronic tiling system for paper documents that supports the ad hoc, multifarious work of information workers. Motivated by interviews with researchers and a survey of descriptive studies of paper document filing, we have focussed on minimizing or delaying costs of document filing and supporting a rich variety of methods for accessing and using stored documents. We have implemented a prototype system called Protofoil for storing, retrieving, and manipulating paper documents as electronic images that integrates many user interface-paper and workstation—and information retrieval technologies. Protofoil has been tested through use in our laboratory. and has been deployed in a field study at a lawyer’s office.

We present a new focus+context (fisheye) scheme for visualizing and manipulating large hierarchies. The essence of our approach is to lay out the hierarchy uniformly on the hyperbolic plane and map this plane onto a circular display region. The projection onto the disk provides a natural mechanism for assigning more space to a portion of the hierarchy while still embedding it in a much larger context. Change of focus is accomplished by translating the structure on the hyperbolic plane, which allows a smooth transition without compromising the presentation of the context.

Current information retrieval interfaces only address a small pant of the reality of rich interactions amongst user, task, and information sources.We view information gathering as an interactive, iterative activity involving multiple disparate information sources and embedded in the context of broader processes of information use.We have developed two key system components that enable information workspaces that adhere to this reformulation of information retrieval.The tlrst is a design for a user/system interaction model for retrieval from multiple, disparate information sources.The second is a repository modeling system, called Repo, that represents meta-information about different information repositories in a manner that supports system operation as well as provides a direct information resource to the user.To test these embodied the interaction system called Labrador.

The Information Grid (InfoGrid) is a framework for building information access applications that provides a user interface design and an interaction model. It focuses on retrieval of application objects as its top level mechanism for accessing user information, documents, or services. We have embodied the InfoGrid design in an object-oriented application framework that supports rapid construction of applications. This application framework has been used to build a number of applications, some that are classically characterized as information retrieval applications, others that are more typically viewed as personal work tools.

The Information Lens provides electronic mail users with the ability to write rules that automatically sort, select, and filter their messages. This paper describes preliminary results from an eighteen-month investigation of the use of this system at a corporate test site. We report the experiences of 13 voluntary users who have each had at least three months experience with the most recent version of the system. We found that:

This paper argues that using a set of semistructured message templates is surprisingly helpful in designing a variety of computer-based communication and coordination systems. Semistructured messages can help provide automatic aids for (1) composing messages to be sent, (2) selecting, sorting, and prioritizing messages that are received, (3) responding automatically to some messages, and (4) suggesting likely responses to other messages. The use of these capabilities is illustrated in a range of applications including electronic mail, computer conferencing, calendar management, and task tracking. The applications show how ideas from artificial intelligence (such as inheritance and production rules) and ideas from user interface design (such as interactive graphical editors) can be combined in novel ways for dealing with semistructured messages. The final part of the paper discusses how communities can evolve a useful set of message type definitions.
