Identifying the occurrences of proper names in text and the entities they refer to can be a diicult task because of the many-to-many mapping between names and their referents. We analyze the types of ambiguity | structural and semantic | that make the discovery of proper names dif-cult in text, and describe the heuristics used to disambiguate names in(More)
Identifying reusable and autonomous components is one of the most important and difficult tasks in developing component-based systems. However, the existing component development methodologies do not provide a clear standard for component identification and depend on the intuition and experience of individual developers. As a result, people with limited(More)
Recently, dynamic behaviors in embedded system for ubiquitous environment and service-oriented system have needed a dynamic coupling metric to evaluate the quality of the software system more accurately. The embedded systems are designed by a component-based system and the component-based system is designed by one object-oriented. Therefore, coupling(More)
Component-Based Development (CBD) is an emerging discipline for promoting practical reuse of software. In CBD, by building new software with independently developed components, we can gain the benefits promised by the software reuse such as quality improvement and rapid development. Accordingly, to improve quality of components, we propose the(More)
Embedded systems that mutually interact with physical space have properties such as time constraint, concurrency constraint, and the control of data/resource flow. The exceptional behaviors of the system that interact with physical space can result in critical damage and cause danger to the operation of an embedded system. Thus, in order to classify and(More)
In ubiquitous environments, the content adaptable services can be dynamically provided to adapt the frequent changes of contexts. These services have common things that the kinds of context factors are limited to ubiquitous environment, though the contexts are flexible. To reuse service architecture can be reasonable for effective adaptable service. In this(More)
