....the information structure being browsed, nor facilitate organization and filtering of information. They provide only rudimentary means to aid users in accessing already visited pages. Recent research offers varied solutions including 3 dimensional, zooming, and metaphorical web browser interfaces [1, 23, 3, 5, 4]. In this paper, a new browsing interface is proposed with multiple window operations and hierarchical windows. It provides a flexible organization in which users can easily organize, filter, and restructure the information on the screen as they reformulate their goals. Overviews can be created ....

.... These approaches can be classified as: ffl 2 D Graph: WebMap [11] Graphic History View [2] Navigational View Builder [18] ffl 3 D: Harmony [1] HyperSpace [23] ffl Hierarchical Windows: IGD [12] VIKI [17] Elastic Windows [14] ffl Zooming: Pad [3] ffl Metaphorical: WebBook [5] DecScape [4] The above list is not complete, but presented here to give an idea of alternative approaches in a classification. The Elastic Windows browser has an advantage over the other hierarchical approaches in that multiple window operations increase user performance and flexibility in arranging pages on ....

....languages are represented as text and as such can be included inside an HTML document, while a general compiled program cannot. Examples of this approach include Java applets [AG96] and Active X controls. There are also many research prototypes based on this approach, such as Tcl [TB96] and Obliq [BN96]. 3.3 Comparative Analysis In this section we summarize and compare all client centric WIS approaches described before. In addition to the criteria analyzed in section 2.4, security will also be analyzed here. Table 2: Comparative analysis of client centric WIS approaches. WIS applications ....

Again, all features of WU Linda, that we define a server side coordination toolkit are easily implementable in Jada. Jada applets are very similar to Oblets, or distributed active objects [BN96]. An oblet is a program written in Obliq and executed on a browser. Each oblet can use high level primitives to communicate with other oblets running on possibly remote browsers. The Bauhaus Turingware Web designed in Yale (the homeland of Linda) is similar at least in spirit to the WU Linda ....

....an incoming method call, it must (a) be executing in the address space of a processor, and (b) arrange for the network software layer running on the object s host to direct arriving method call requests to a communication port reserved for the object. In this paper, we term these active objects[2, 3] 1 1 Note that the definition of active object in the mobile agent community is often that of an object which moves from one location to another and, once there, obtains a thread of con As a motivating example, consider an airline that exposes each flight as an object on the network.

....such as groupware and multi player games. Our distributed applet technology is based on Obliq [5] an object oriented scripting language that was specifically designed for constructing distributed applications in a heterogeneous environment. We call applets written in Obliq Oblets (Obliq applets) [2]. We have built a family of Web browsers that support Oblets [1, 4] Obliq supports distributed computation by implementing all objects as network objects. The methods of a network object can be invoked by other processes, in addition to the process that created the object. The initial connection ....

Our active objects resemble Java applets in that the code for algorithms and views is downloaded over the network, and then executed by and displayed in the Web browser [4]. The innovation of CAT is that it displays multiple, simultaneously animated views of an algorithm. The views either may appear on a single page, or on separate pages. Moreover, multiple users viewing the same page will see the same animation; those views that allow customization can be ....
