Short staffing and insufficient technical and business knowledge among staff members can hinder information centers from meeting the needs of end users. Establishing groups of selected users with special skills improves end-user computing by opening communication channels, influencing training objectives, and fostering better user morale. This article explains the types of user groups that an information center can establish and the benefits to be derived from them.  相似文献

As the products of new technologies proliferate, they are accompanied by a corresponding rise in problems concerning their selection, use, and maintenance. Any hardware and software products may reveal quirks or outright failures even after the most rigorous testing by both seller and buyer. Solving these problems is often beyond the capability of in-house personnel. Although an obvious solution is to turn to the vendor for help, an alternative does exist—other users of the same product.  相似文献

Abstract

Every software system, whether designed for commercial or noncommercial use, must be documented. Documentation must be geared to users' needs and knowledge; it should be neither too technical nor too simple. The quality of documentation is a major determinant of how well a system is received and how widely it is used.  相似文献

In this paper we deal with the high level management of data involved in Location-Based Services in order to accommodate corresponding queries. A series of techniques are employed on major components of an LBS, namely mobile users, application environment and selected services. First, a grouping technique generalizes the spatio-temporal data describing the mobile users' movement. The environment is represented under a combined spatial and content hierarchy according to the application at hand. Finally, in the service component, relational operators are formed to support relative spatio-temporal queries, while lifeline data types are constructed to extract and compare behavioral trend patterns among the formed user groups. We show how all proposed techniques communicate under a common database schema. Answers to characteristic queries demonstrate the applicability of this work.  相似文献

支持个性化检索的User Profile研究概述   总被引:2,自引:0,他引:2  
在现代搜索系统中,由于网络信息的动态性和用户兴趣的迁移性,通常的检索技术已难以满足用户的个性化需求,个性化搜索势在必行.User Profile作为描述用户兴趣和爱好的载体和手段,是个性化搜索领域的重要组成部分之一.本文论述了User Profile的创建、学习、存储、更新及其在个性化搜索系统中发挥的作用等,分析在相关反馈过程中,利用User Profile进行查询扩展的具体过程.针对向量空间模型和概率模型,分别讨论了User Profile的更新问题.最后,展望了User Profile的发展方向,得出"基于本体的User Profile是目前和将来最具潜力的方法"的结论.  相似文献

Abstract

When taking a typical approach to computer security, one could make the following relatively extreme statements: A piece of data can be rendered completely secure with 100 percent assurance. Simply write the data on a piece of paper, burn the paper, and scatter the ashes. No one will be able to read or alter that data ever again. Of course, this exercise and the underlying premise are a trick. Understanding the deception is the key to understanding information security: Data that is being “protected” has to remain available to legitimate users. There is a strong tendency for information security researchers and practitioners to focus on “securing” data by preventing attacks and loss of data. An IS practitioner's job might depend on preventing and recovering from security-related problems. However, increased monitoring and enhanced use of security controls can easily lead to interference and delays of information usage for legitimate users.  相似文献

用户兴趣模型的表示是信息过滤中的关键技术,它直接关系到过滤效果的好坏。比较了三种不同的用户兴趣模型:传统的关键字表示法、固定文章集法F D S (文章表示法)和基于示例法(段落表示法) ,并对它们进行了实验分析,得出后两种方法要优于第一种的结论。其技术的关键在于如何描述和更新用户的兴趣模型。  相似文献

Today, digitally stored information isn't only ubiquitous, it's also increasing in volume at an exponential rate. And not only is the volume increasing, but so is the variety, as well as the ways of combining information from different sources to derive insights. Not surprisingly, our most pressing technological and business problem is finding what we need in this sea of information. The dominant paradigm for addressing this problem is information retrieval (Modem Information Retrieval, Ricardo Baeza-Yates and Berthier Ribeiro-Neto, ACM Press, 1999). In this paradigm, the user enters a query (typically a few words typed into a search box), and the system retrieves documents matching the query, ranking the matches based on an estimate of their relevancy to the query. If the system finds many matches, the user sees only the highest-ranked matches. The popularity of Web search systems such as Google shows that the information retrieval paradigm can be effective. An information access framework empowers users by explicitly focusing on the interaction between users and the system. The key problem for information access systems isn't guessing which matching document is most relevant, but establishing a dialogue in which users progressively communicate their information goals while the system provides immediate, incremental feedback that guides users in the pursuit of those goals  相似文献

Customising Web Information Systems According to User Preferences   总被引:1,自引:0,他引:1  
Web Information Systems have to serve a variety of users with very diverse preferences regarding content, functionality and presentation. We first investigate the customisation of functionality at a high-level of abstraction, where possible action sequences are represented by an algebraic expression called plot, and user preferences give rise to equations. We show that the problem can be solved by applying conditional term rewriting on the basis of Kleene algebras with tests. By exploiting the idea of weakest preconditions such expressions can be represented by formal power series with coefficients in a Boolean algebra. This gives rise to a sufficient condition for termination based on well-founded orders on such power series. As confluence cannot be guaranteed, we propose critical pair completion to be used in order to enforce the desirable Church-Rosser property. In a second step we parametrise the actions and replace the Boolean conditions by first-order formulae. We show that still term rewriting can be applied, but termination and Church Rosser property become problems that will require manual interaction, in particular, as preference rules will make use of the parameters. On the other hand the presence of first-order conditions can be used to extend the customisation to the content.  相似文献
