复杂软件系统客户创意知识分析与获取研究

复杂软件系统研发模糊前端的创意过程需要大量知识支持。其中客户拥有的知识,客户与软件研发团队交互过程中产生的知识,构成了客户创意知识,是复杂软件系统研发模糊前端创意知识的重要组成部分。为了获取客户创意知识,在系统地分析了它的内涵与类型后,采用情境交互理论构建了复杂软件系统客户创意知识获取的模型,探索了客户创意知识获取的步骤、方法、技术平台。研究发现,与传统知识获取相比,以情境交互为基础,融合信息技术、智能计算和社会网络技术的知识获取方法具有显著优势,为复杂软件系统研发模糊前端的客户创意知识获取提供了有力的支持。

Discovering power laws in computer programs

The power-law regularities have been discovered behind many complex natural and social phenomenons. We discover that the power-law regularities, especially the Zipf’s and Heaps’ laws, also exist in large-scale software systems. We find that the distribution of lexical tokens in modern Java, C++ and C programs follows Zipf–Mandelbrot law, and the growth of program vocabulary follows Heaps’ law. The results are obtained through empirical analysis of real-world software systems. We believe our discovery reveals the statistical regularities behind computer programming.     

对GMP认证中存在问题的探讨

GMP认证制度是国家对药品生产企业监督检验的一种手段,也是保证药品质量的一种科学、先进的管理方法。企业在GMP认证和实施的过程中,存在着与GMP要求不相符合的现象。人们对GMP的认识还有待于提高,我国的GMP认证管理工作应进一步加强。     

VBA技术在医院门诊收费管理系统中的应用

介绍了医院门诊管理系统软件中医院门诊计算过程采用数据交换和自动输出功能实现的技术原理及编程方法:应用VBA技术对Excel文件分别进行后台操作,然后实现两者文件的合并,统一以Word文件的形式输出。这对其他具有报表输出功能的软件系统开发有一定的参考价值。     

Classifying web genres in context: A case study documenting the web genres used by a software engineer

This case study analyzes the Internet-based resources that a software engineer uses in his daily work. Methodologically, we studied the web browser history of the participant, classifying all the web pages he had seen over a period of 12 days into web genres. We interviewed him before and after the analysis of the web browser history. In the first interview, he spoke about his general information behavior; in the second, he commented on each web genre, explaining why and how he used them. As a result, three approaches allow us to describe the set of 23 web genres obtained: (a) the purposes they serve for the participant; (b) the role they play in the various work and search phases; (c) and the way they are used in combination with each other. Further observations concern the way the participant assesses quality of web-based resources, and his information behavior as a software engineer.

Knowledge meaning and management in requirements engineering

It is traditionally assumed that requirements specification, as a product of requirements engineering, has a high impact on the ensuing software development stages. Therefore, the knowledge management used to construct the requirements specification should be performed in a structured manner to discover, analyze and understand the data–information–knowledge chain, both tacit and explicit, that the interested parties possess. In this article, the results of a literature review are presented, seeking to answer the following questions: (1) What is the meaning of knowledge in requirements engineering? (2) What approaches are proposed to manage knowledge in requirements engineering? (3) Can the efficiency and the efficacy of knowledge management models be evidenced in requirements engineering? Thirty-six works were chosen for analysis out of a total 83 found in our search. The analysis showed that (1) knowledge has a central significance at this stage, but the authors have yet to agree on the best methods to impart and apply that knowledge; (2) no general framework has emerged as a validated approach to manage knowledge for requirements engineering; and (3) the evaluation marks for model efficiency and efficacy are low, consisting mostly of personal interpretations.
