Reuse of Specifications and Designs in a Development Information System
نویسندگان
چکیده
This paper describes the approach to application specification and design via reuse at the basis of the Development Information System of the ITHACA2 environment. Requirements and detailed design of a specific application are incrementally composed by aggregating available reusable components stored in the Software Information Base repository. The paper reviews the Development Information System, then focuses on two tools of the system: RECAST (Requirements Composition And Specification Tool) and Visual ADL, which help the developer in selecting reusable artifacts from the Software Base and in composing and tailoring them according to the specific needs of the application. The paper illustrates the composition approach and describes how reuse is supported via meta classes incorporating suggestions for component reuse and tailoring, and for detailed design. Keyword Codes: D.1.7; D.2.1; D.1.5

A Knowledge-based Support System for the Reuse of Structured Specifications and Designs of Embedded Computer Systems
THE AND Reuse promises to be one of the key factors in enhancing quality and productivity in software development. However, CASE tools for real-time systems are usually focused on the development of new software. In this paper we describe a domain-based support system for the reuse of structured software specifications and designs of embedded software! .
متن کاملBoosting Passage Retrieval through Reuse in Question Answering
Question Answering (QA) is an emerging important field in Information Retrieval. In a QA system the archive of previous questions asked from the system makes a collection full of useful factual nuggets. This paper makes an initial attempt to investigate the reuse of facts contained in the archive of previous questions to help and gain performance in answering future related factoid questions. I...
متن کاملInvestigating Embedded Question Reuse in Question Answering
The investigation presented in this paper is a novel method in question answering (QA) that enables a QA system to gain performance through reuse of information in the answer to one question to answer another related question. Our analysis shows that a pair of question in a general open domain QA can have embedding relation through their mentions of noun phrase expressions. We present methods f...

متن کاملR-Tool: A Supporting Tool for a Quality Oriented Reuse Strategy
The quality of reusable elements must be rigorously monitored and guaranteed before they can be reused, this is known as Certification. High levels of certification of these elements generate trust and stimulate reuse. In this paper we describe the development of a tool based on quality oriented reuse strategies. To this end, we take as starting point an ontology that rigorously correlates the ...
