Based on the requirement analysis of specification languages, a new software decomposition model is proposed, and an abstract data type definition method combining both the algebraic and the flrst-order logic descriptions is adopted in GSPEC. With its graphical representation, the correctness of its specifications can be guaranteed or verified to some extent. The language is powerful and easy to understand. It has been implemented on IBM PC/AT computers and SUN-3/160 C work stations.展开更多

Ensuring high quality serviceis challenging as it not only demands detailed domain-specific knowledge, but also the ability toquickly understand the clients＇ issues through their diverse - and often casual - descriptions. Thispaper aims to provide a framework for the development of an automated information broker agent whoperforms the task of a helper. The main task of the agent is to interact with the client and direct them toobtain further services that cater their personalized need. To do so, the agent should accomplish asequence of tasks that include natural language inquiry, knowledge gathering, reasoning, and givingfeedback; in this way, it simulates a human helper to engage in interaction with the client. Theframework combines a question-answering reasoning mechanism while utilizing domain-specificknowledge base. When the users cannot describe clearly their needs, the system tries to narrow downthe possibilities by an iterative question-answering process, until it eventually identifies the target. Inrealizing our framework, we make a proof-of-concept project, M andy, a primary care chatbot systemcreated to assist healthcare staffs by automating the patient intake process. We describe in detail thesystem functionalities and design of the system, and evaluate our proof-of-concept on benchmark casestudies.展开更多

More and more scientists, researchers and software developers are using GPUs to accelerate their algorithms and ap- plications. Developing complex programs and software on the GPU, however, is still far from easy with ex- isting tools provided by hardware vendors. This article introduces our recent research efforts to make GPU soft- ware development much easier. Specifically, we designed BSGP, a high-level programming language for general- purpose computation on the GPU. A BSGP program looks much the same as a sequential C program, and is thus easy to read, write and maintain. Its performance on the GPU is guaranteed by a well-designed compiler that converts the program to native GPU code. We also developed an effective debugging system for BSGP pro- grams based on the GPU interrupt, a unique feature of BSGP that allows calling CPU functions from inside GPU code. Moreover, using BSGP, we developed GPU algorithms for constructing several widely-used spatial hierarchies for high-performance graphics applications.展开更多
