Traditionally, access for performing system administration tasks is an all or nothing proposition. With root access, an administrator can potentially make many changes to a system even though you may only want to allow them to add a user or mount a filesystem. In addition to specific tasks, you may want to control what tasks an administrator can perform based on which machine they are using. Fo...

one of the most problematic areas in foreign language learning is collocation. it is often seen as arbitrary and an overwhelming obstacle to the achievement of nativelike fluency. current second language (l2) instruction research has encouraged the use of collaborative output tasks in l2 classrooms. this study examined the effects of two types of output tasks (editing and cloze) on the learning...

The amount of machine oriented data on the web as well as the deployment of agent/Web Services are simultaneously increasing. This poses a service-discovery problem for client agents wishing to discover Web Services to perform tasks. We discuss a prototype mathematical service broker and look at an approach to circumventing the ambiguities arising from alternative but equivalent mathematical re...

Software development and maintenance tasks rely on and can beneet from an increased level of program understanding. Object-oriented programming languages provide features which facilitate software maintenance, yet the same features often make object-oriented programs more diicult to understand. We support the use of program visualization techniques to foster object-oriented program comprehensio...

Cerberus is one of the four new teams in the RoboCup Tournament, Legged Robot Category. The team is a joint e ort of Bo gazi ci University (Turkey) and Technical University of So a, Branch Plovdiv (Bulgaria). We have divided the robot software design into six major tasks, and worked on those tasks in parallel. With limited time in our hands, our aims were a clear object oriented design, readabl...

We describe a framework for deep linguistic processing for natural language understanding in task-oriented spoken dialogue systems. The goal is to create domaingeneral processing techniques that can be shared across all domains and dialogue tasks, combined with domain-specific optimization based on an ontology mapping from the generic LF to the application ontology. This framework has been test...

This paper describes research on developing a customisable tool for visualising object-oriented software at runtime. This aims to highlight both the static and dynamic structure of the software and aid software engineers in tasks requiring program comprehension of the code. The paper specifically looks at some of the customisation support provided by the tool and how a simple representation can...

In this paper we present a role based approach to the analysis of computer-based information systems (ISs). The concept of work role is a good tool for representing work and division of labour, and the computer supported tasks make no exception of this. Relationships between actors, roles, tasks and computer systems are discussed from the act-oriented perspective. Role based analysis of an acti...

What visual program abstractions support program-ming? We explore this question for object-oriented programming with reference to programming tasks such as modiication engineering and program development. We present ten related abstractions (views) of a program using visual constructs based on empirical and observational studies. We explain the dynamic and interactive nature of the views and su...
