최근 다양한 직업을 가진 SNS 사용자가 증가함에 따라, SNS 사용자들은 전문가 간 협업 및 기술적 의사소통을 위한 전문가 추천 기능을 요구하고 있다. 하지만 기존 협업적 여과 기법은 전문가 추천 서비스를 효율적으로 제공하지 못한다. Content-boosted 협업적 여과 기법은 다양한 예측 알고리즘을 제시하여, 효과적인 추천을 수행할 수 있도록 지원한다. 그러나 명확한 계산 조건이 제시되지 못하는 경우 아이템 및 사용자 유사도 계산을 수행할 수 없는 단점이 존재한다. 따라서 본 논문에서는 Content-boosted 협업적 여과 기법의 단점을 해결하는 하이브리드 협업적 여과기법을 이용한 새로운 전문가 추천기법을 제안한다. 또한, 이를 이용하여 SNS에서의 전문가 추천 시스템을 설계한다.

In the defense software domain where large-scale software products in various application areas need to be built, reusing software is regarded as one of the important practices to build software products efficiently and economically. There have been many efforts to apply various methods to support software reuse in the defense software domain. However, developers in the defense software domain still experience many difficulties and face obstacles in reusing software assets. In this paper, we analyze practical problems of software reuse in the defense software domain, and define core requirements to solve those problems. To meet these requirements, we are currently developing the Component Grid system, a reuse-support system that provides a developer-centric software reuse environment. We have designed an architecture of Component Grid, and defined essential elements of the architecture. We have also developed the core approaches for developing the Component Grid system: a semantic-tagging-based requirement tracing method, a reuse-knowledge representation model, a social-network-based asset search method, a web-based asset management environment, and a wiki-based collaborative and participative knowledge construction and refinement method. We expect that the Component Grid system will contribute to increase the reusability of software assets in the defense software domain by providing the environment that supports transparent and efficient sharing and reuse of software assets.

Due to science and technology evolutions, modern systems are becoming larger and more complex. In developing complex systems, Model-Based Systems Engineering (MBSE), which is approach to reduce complexity, is being introduced and applied to various system domains. However, because of the modeling being made through a variety of languages, there is a problem with communication within the stakeholders and a lack of consistency in the models. In this paper, by investigating the rule explaining the transformation of one of the only traditional diagrams, DFD, to SysML and reusing the formerly built models, we attempt to implement by SysML. Analyzing each diagram's Metamodel and validating the connection of each component through bipartite graph especially suggest an effective transformation rule. Also, by applying to naval-combat system, we confirm efficiency of this study. Establishing the results of this study as basis for conducting further study, we will be able to transform other previous models gained from formerly built system to SysML. In this way, the stakeholder's communication can be improved and we anticipate that the application of SysML will be beneficial to the much efficient MBSE.

Social enterprises have a high cost structure, inefficient operation, and poor human and material resources due to a dual structure that must achieve both economic and social purposes. To solve this problem, collaboration, such as sharing resources and information between social enterprises, is emerging as an important management issue. Accordingly, in recent years, the establishment and operation of an online platform is being emphasized as a means to effectively support the problem of lack of resources (human resources, equipment, funds, and technology) between social enterprises, the promotion of joint projects between companies, and the establishment of organic information sharing and communication channels between companies. This study empirically analyzed how the required characteristics of the online platform that supports the collaboration of social enterprises vary depending on the characteristics of the enterprise (general characteristics, collaboration characteristics), and found that there are statistically significant differences depending on the size. These results are expected to be useful in deriving management plans for online platforms for cooperation support for domestic social enterprises in the future, and seeking ways to increase collaboration using the platforms.
