A Contextual Item-Based Collaborative Filtering Technology  [PDF]
Xueqing Tan, Pan Pan
Intelligent Information Management (IIM) , 2012, DOI: 10.4236/iim.2012.43013
Abstract: This paper proposes a contextual item-based collaborative filtering technology, which is based on the traditional item-based collaborative filtering technology. In the process of the recommendation, user’s important mobile contextual information are taken into account, and the technology combines with those ratings on the items in the users’ historical contextual information who are familiar with user’s current context information in order to predict that which items will be preferred by user in his or her current context. At the end, an experiment is used to prove that the technology proposed in this paper can predict user’s preference in his or her mobile environment more accurately.
An OWL-Based Mobile GeoBI Context Ontology Enabling Location-Based and Context-Based Reasoning and Supporting Contextual Business Analysis  [PDF]
Belko Abdoul Aziz Diallo, Thierry Badard, Frédéric Hubert, Sylvie Daniel
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.61007
Abstract: Mobile professionals need to be assisted with suitable mobile GeoBI (Geospatial Business Intelligence) systems, which are able to capture, organize and structure the user’s reality into a relevant context model and reason on it. GeoBI context modelling and reasoning are still research issues since there is not yet either a model or a relevant taxonomy regarding GeoBI contextual information. To fill this gap, this paper proposes an extended and detailed OWL-based mobile GeoBI context ontology to provide context-aware applications and users with relevant contextual information and context-based reasoning capabilities. Context quality issues are handled an implementation architecture which is provided.

Disparity between Ideals and Reality in Curriculum Construction: The Case of the Lebanese English Language Curriculum  [PDF]
Kassim Ali Shaaban
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.412A2005
Abstract: This paper describes the disparity between the principles, guidelines, suggested themes, organization, methodology, classroom activities, and assessment outlined in the thematic, content-based English language curriculum adopted by the Lebanese government in 1997 and the classroom realities and other contextual factors that have hampered its proper implementation. The paper shows that the curriculum is designed in line with international ESL/EFL standards as it has clear goals, objectives, and performance indicators as well as sound perspectives on instruction, material selection and adaptation, and evaluation guidelines. These perspectives are based on widely accepted theoretical views in language acquisition and best practices in English language education. However, the content-based curriculum normally demands a high level of language proficiency and content and pedagogical knowledge from teachers, and it is highly dependent on the availability of adequate resources and ongoing professional development programs. The educational context in Lebanon still suffers the effects of the 1975-1990 civil war in these areas, which has made the implementation fraught with all sorts of problems.

Research on Dynamic Capabilities and Innovation Performance in the Chinese Context: A Theory Model-Knowledge Based View  [PDF]
Yun Gao, Yongmei Zhu
Open Journal of Business and Management (OJBM) , 2015, DOI: 10.4236/ojbm.2015.34035
Abstract: To carry out contextualized research on theory of dynamic capabilities under the perspective of the knowledge-based, and explore the mechanism of international enterprises to enhance innovation performance in the Chinese context, also to build a theoretical model between “the Chinese context-dynamic capabilities-innovation performance”, this study makes an attempt to theoretical research and management practices with combining the Chinese context. The study finds that building dynamic capability is the inevitable result of enterprises to survive and develop in the Chinese context, and it makes a contribution to knowledge transferring, sharing and creating in the international market, ultimately to enhance innovation performance, overcome latecomer disadvantages.
Creativity in Science: Tensions between Perception and Practice  [PDF]
Adele L. Schmidt
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.25063
Abstract: Many countries are reviewing science education programmes and implementing new pedagogical paradigms aimed at reversing a trend of declining enrolments. A key factor in this decline is a public perception that science is not a creative endeavour. Attempts to reframe public perception tend to focus on primary and secondary schooling, but do little to address ongoing declines in quality and originality of intellectual output beyond the highschool environment. To overcome systemic devaluation of science requires appreciation of the complex, dynamic, and often stochastic, interplay of sociocultural, psychological and cognitive factors that drive human creativity. Viewing creativity from this perspective reveals tensions between perception and practice that limit opportunities for students, science educators and scientists. Resolving the tension requires integration of developmental, psychometric and sociocultural discourses of creativity in ways that generate opportunities for individuals at all levels of education and practice to: 1) acquire a high level of domain-specific knowledge; 2) practise application of that knowledge in developing solutions to problems across a gradient of difficulty and; 3) be challenged to integrate their knowledge of science with their knowledge of other fields to pursue and solve problems with personal relevance.
A Design of Incremental Granular Network for Software Data Modeling  [PDF]
Keun-Chang Kwak
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.311120
Abstract: In this paper, we propose an incremental method of Granular Networks (GN) to construct conceptual and computational platform of Granular Computing (GrC). The essence of this network is to describe the associations between information granules including fuzzy sets formed both in the input and output spaces. The context within which such relationships are being formed is established by the system developer. Here information granules are built using Context-driven Fuzzy Clustering (CFC). This clustering develops clusters by preserving the homogeneity of the clustered patterns associated with the input and output space. The experimental results on well-known software module of Medical Imaging System (MIS) revealed that the incremental granular network showed a good performance in comparison to other previous literature.
Understanding Requirement Engineering for Context-Aware Service-Based Applications  [PDF]
Seyed Hossein Siadat, Minseok Song
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.58062
Abstract: Requirements of software systems tend to change over time. The speed of this tendency depends on the application domain the software system under consideration belongs to. If we consider novel contexts such as pervasive systems and systems supporting dynamic B2B interaction, requirements change so fast that the research community is studying how to build systems that are able to self-adapt on the fly to some of these changes. When this happens, the system does not need to undergo through a new development cycle thus increasing its availability and, to a certain extent, its robustness. So far, the research in the area of self-adaptive systems has been focusing on the definition of the mechanisms for supporting self-adaptation. We argue that what is missing now is a structured and robust design process associated to these mechanisms. This design process should include a Requirement Engineering (RE) phase that somewhat differs from the traditional one. However, the identification of requirements for adaptation requires a good knowledge of the context in which the system will be executed. In this work, we consider the modeling of such context as part of the RE phase and we particularly focus on Service-Based Applications (SBAs). We argue that RE activities should be supported at run-time to handle context changes and to support adaptation for SBAs. We survey the state of the art for what concerns the elicitation, modeling, and analysis of requirements and will highlight some issues and challenges in order to support adaptation for SBAs.
An Investigation on the Comparison of Context Based and Traditional Physics Problems
Ahmet TEKBIYIK,Ali R?za AKDEN?Z
Necatibey Faculty of Education, Electronic Journal of Science and Mathematics Education , 2010,
Abstract: The aim of this study is to investigate the effectiveness of context based and traditional physics problems comparatively. First of all, we reviewed the literature and assigned some criteria in order to prepare context based problems, and developed two different tests as context based and traditional based physics tests based on the described criteria. Secondly these tests were applied to 30 high school students. Also we held an interview with randomly selected five students in order to determine the views of students about the differences between these two different tests. A semi-structured interview form was used in this interview process. Finally, we used a paired-samples t test in order to compare students’ achievements scores on these two different tests. Content analysis method was performed to analysis qualitative data collected through interviews. Study findings showed that there was no significant difference between students’ context based and traditional test scores. However, students appreciated context based problems more understandable, concrete and interesting than traditional ones.
