An Open Source Software (OSS) project is unlikely to be successful unless there is an accompanied community that provides the platform for developers and users to collaborate. Members of such communities are volunteers whose motivation to participate and contribute is of essential importance to the success of OSS projects. In this paper, we aim to create an(More)
End-user development (EUD) activities range from customization to component configuration and programming. Office software, such as the ubiquitous spreadsheet, provides customization facilities, while the growth of the Web has added impetus to end-user scripting for interactive functions in Web sites. In scientific and engineering domains, end users(More)
Open-Source Software (OSS) development is regarded as a successful model of encouraging "natural product evolution". To understand how this "natural product evolution" happens, we have conducted a case study of four typical OSS projects. Unlike most previous studies on software evolution that focus on the evolution of the system per se, our study takes a(More)
Despite its well-recognized benefits, software reuse has not met its expected success due to technical, cognitive, and social difficulties. We have systematically analyzed the reuse problem (especially the cognitive and social difficulties faced by software developers who reuse) from a multidimensional perspective, drawing on our long-term research on(More)
Technical, cognitive, and social factors inhibit the widespread success of systematic software reuse. Our research is primarily concerned with the cognitive and social challenges faced by software developers: how to motivate them to reuse and how to reduce the difficulty of locating components from a large reuse repository. Our research has explored a new(More)

The power of the unaided individual mind is highly overrated. Although society often thinks of creative individuals as working in isolation, intelligence and creativity result in large part from interaction and collaboration with other individuals. Much human creativity is social, arising from activities that take place in a context in which interaction(More)
Although software reuse can improve both the quality and productivity of software development, it will not do so until software developers stop believing that it is not worth their effort to find a component matching their current problem. In addition, if the developers do not anticipate the existence of a given component, they will not even make an effort(More)
An inherent dilemma exists in the design of high-functionality applications (such as repositories of reusable software components). In order to be useful, high-functionality applications have to provide a large number of features, creating huge learning problems for users. We address this dilemma by developing intelligent interfaces that support learning on(More)
