超级便笺Windows为你贴!

对于用在电脑桌面上的备忘便笺，我向有着“苛刻”的要求：便笺必须一直“钉”在桌面上，不能在其他程序窗口之间上下乱窜。也不能有事没事就从桌面上消失（那我还要它干嘛）……．试用过不少便笺软件后，我发现其实根本不用找——Windows的“自定义桌面”就能很好地实现我所需要的便笺功能。这种便笺不仅大小、外观可以随心定制，而且还能加入提醒所需的文件链接或网站链接。[编者按]

Automatic authoring and construction of hypermedia for information retrieval

This paper describes the complete process and a tool for the automatic construction of a multimedia hypertext starting from a large collection of multimedia documents. Through the use of an authoring methodology, the document collection is automatically authored, and the result is a multimedia hypertext, also called a hypermedia, written in hypertext mark-up language (HTML), almost a standard among hypermedia mark-up languages. The resulting hypermedia can be browsed and queried with Mosaic, an interface developed in the framework of the World Wide Web Project. In particular, the set of methods and techniques used for the automatic construction of hypermedia is described in this paper, and their relevance in the context of multimedia information retrieval is highlighted.     

A Schematic Entry Drawing Capability in a Linearised Hypermedia System

This paper describes a linearised hypermedia system, called the Book Emulator, that generally supports the capture of diagrammatic specifications such as SSADM and electronic circuit diagrams, and the capture of mathematical notations such as Z. Since the Book Emulator can be closely coupled to applications, it can be used as the user-interface to that application. Doing so automatically provides a conferencing mechanism on behalf of applications and a mechanism for recording the engineering analyses performed by the application. It is argued that this is the next and higher step in the trend to separate the user-interface from the application. The schematic entry mechanism has been designed to minimise the user's physical and mental effort so that the user may concentrate on drawing strategy. This is achieved by minimising the number of selections (steps) required to reach an atomic goal, and by refraining from hiding functionality in menus. The paper concludes with an indication of how the generalised schematic capture mechanism might be exploited in systems that allow end- users to organise and specify their information requirements.     

Design and Query Strategies to Hypermedia Applications

In this paper we propose an object-oriented model for designing hypermedia applications. As the object-oriented paradigm allows complex and user-defined types, nonconventional and nonatomic attributes, we can take advantage of these capabilities, not only for information modelling, but also for providing alternative ways for accessing information.A query language is then presented; it is based on an Object-Oriented Database System query language. It combines features of object-oriented databases queries and primitives for hypermedia navigation. The language offers the possibility of querying both the application-domain information, and allowing the designers to obtain information about the schema of the application.We present some examples of the use of the object-oriented model and the query language.

An Open Model for Hypermedia and Its Application to Geographical Information Systems

This paper describes the design and implementation of a multimedia information management environment that is based on an open model for hypermedia. The model, known as Microcosm, is currently implemented in Microsoft Windows and supports many different media types. The open nature of the model and the separation of the links from the data, allows links to be applied across any application running under Windows or the OS/2 version 2 desktop, thus creating a truly integrated environment. One example, which is, discussed in the paper, is the integration of a hypermedia database with a geographical information system. The paper also discusses the application of novel interfaces to dynamic media within a hypermedia system, including the use of moving icons (micons).
