Depth study of the network environment based on software engineering theory and cutting-edge technology to improve the competitiveness of China's software industry breakthrough. Only by having a strong independent research and development of software innovation can fundamentally industrial upgrading its software, and resolve network resources brought by the deepening of the software application bottlenecks...
At present, several feature meta-models have been come up with. However, they can't meet the requirements of dynamic Internet environment or software reuse. This paper proposes a feature meta-model based on ontology. In particular, it can adapt to various types of changes in the dynamic environment and can make design and implementation more convenient than traditional methods. Finally, we give out...
Requirements specification and analysis is a critical step in any system engineering process and the quality of identified requirements is crucial for the success of projects. A complete understanding of stakeholders' problems and their concise and clear representation as well as a representation understandable for stakeholders helps to design software that meet customers' needs. With the help of...
The main problem of enterprise application evolution is how to capture requirements and then propagate requirement changes to application. Effectively evolving enterprise application with the frequently changing requirements is still a challenge to software engineering. Requirement is the root causes of evolution of enterprise applications in many cases. Refactoring has given guidance to gradual evolution...
Service-oriented software engineering emphasizes the discovery and reuse of existing service resources and aggregate them to meet user needs. This paper proposes a service-oriented and process-driven approach to modeling variability in software product line. In this approach, variability analysis and modeling as a means, domain ontology model as a starting point, process ontology model as the center,...
This paper proposes and illustrates an approach to identify and specify requirements on information-based business services and their associated derived software services. The approach proposes first to identify business services by modeling business requirements using the goal oriented modeling notation i*. Then, in a second phase, the identified services are refined according to these requirements...
To reduce the practicing defects in ration unified process, this paper introduces a new requirement modeling process, which is based on the analysis of rational unified process with the combination of agile modeling technique. Contents of this process includes: getting the requirement in a general way, planning the developing schedule according to the requirement priority and simplifying requirement...
The idea of ontology-based approach to business process modeling is certainly viable. However, according to the semantic representation deficiency of the process models, it's hard to realize the ontology auto-acquisition to support the model mapping from domain model to IT-specific PIM. This paper presents an ontology-activity-based model acquisition approach to improve business process modelling...
Twenty years ago, an effort to build a reuse-based software generator led to the realization that a domain-specific focus was essential to achieving effective software reuse. This realization became the product line vision. However, reuse was never the primary focus of this vision but only a means to an end: achieving the ability to rapidly produce and evolve high-quality software. Although the spirit...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
The challenges of deriving early-adopter competitive advantage, even with fabless access to process technology, through leveraging features offered by the advanced, and possibly disruptive, process technologies in real SoC products, are outlined. A structured methodology for addressing these challenges, and bridging the gap between process and design, sufficiently early in the development cycle to...
Digital Earth (DE) is a virtual presentation of the planet based on geographic coordinate, and is an information system with tremendous amount of multiple resolutions and multiple scales data as shown in multiple dimensions. It can visualize the real earth and represent historical phenomena in digital way by using the large amount of data of the earth, and utilizing the computer techniques, image...
We present features of an education system entirely based on a 7-months project, performed by a 6-students team within a virtual company and tutored by an experimented software engineer. We describe some aspects of a past project: functions of the system, technology, deliverables, and assessment. Students' outcomes are drafted in term of roles.
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
