Ubiquitous Healthcare (u-Healthcare) is the intelligent delivery of healthcare services to users anytime and anywhere. To provide robust healthcare services, recognition of patient daily life activities is required. Context information in combination with user real-time daily life activities can help in the provision of more personalized services, service suggestions, and changes in system behavior based on user profile for better healthcare services. In this paper, we focus on the intelligent manipulation of activities using the Context-aware Activity Manipulation Engine (CAME) core of the Human Activity Recognition Engine (HARE). The activities are recognized using video-based, wearable sensor-based, and location-based activity recognition engines. An ontology-based activity fusion with subject profile information for personalized system response is achieved. CAME receives real-time low level activities and infers higher level activities, situation analysis, personalized service suggestions, and makes appropriate decisions. A two-phase filtering technique is applied for intelligent processing of information (represented in ontology) and making appropriate decisions based on rules (incorporating expert knowledge). The experimental results for intelligent processing of activity information showed relatively better accuracy. Moreover, CAME is extended with activity filters and T-Box inference that resulted in better accuracy and response time in comparison to initial results of CAME.

Natural Language Question Answering (NLQA) and Prescriptive Analytics (PA) have been identified as innovative, emerging technologies in 2015 by the Gartner group. These technologies require knowledge bases that consist of data that has been extracted from unstructured texts. Every business requires a knowledge base for business analytics as it can enhance companies' competitiveness in their industry. Most intelligent or analytic services depend a lot upon on knowledge bases. However, building a qualified knowledge base is very time consuming and requires a considerable amount of effort, especially if it is to be manually created. Another problem that occurs when creating a knowledge base is that it will be outdated by the time it is completed and will require constant updating even when it is ready in use. For these reason, it is more advisable to create a computerized knowledge base. This research focuses on building a computerized knowledge base for business using a supervised learning and rule-based method. The method proposed in this paper is based on information extraction, but it has been specialized and modified to extract information related only to a business. The business knowledge base created by our system can also be used for advanced functions such as presenting the hierarchy of technologies and products, and the relations between technologies and products. Using our method, these relations can be expanded and customized according to business requirements.

Recent IT (information technology) environmental changes, such as emerging social network services or increasing user participation in multimedia environment, have made it necessary for e-learning systems to undergo changes in various ways. Metadata is an agreement for interoperability between different systems. The standardization of metadata for e-learning system has been driven by some domestic and international organizations, but applying diverse environmental changes into the design of e-learning metadata is in dire need. In this paper, we present a methodology for the analysis and design of modeling e-learning metadata and elicit the design requirements, on the basis of the metadata standard KEM 3.0, about the elements that are expected to be needed in future e-learning systems. Based on the requirements from the analysis, we present the three-layer model for classifying the requirements by the importance of metadata elements per Kana Model. An intelligent e-learning system is to be developed based on the proposed modeling design, which we hope to influence the development of an international standard in the future.

학술 문서 내에서 테이블은 실험 결과, 정의, 요약하는 정보들을 함축하여 사용자에게 제공하는 역할을 한다. 즉 이러한 테이블을 학술 문서 내에서 탐색, 추출하여 검색에 이용하는 것은 학술 문서의 이해를 돕는 것과 더불어 학술 문서를 사용자가 직접 작성할 때에도 비슷한 형태의 테이블을 참조하여 형식에 맞는 테이블을 작성하는 데에 도움을 준다. 따라서 본 연구는 이러한 다양한 목적의 테이블 검색을 지원하기 위하여 문서로부터 자동으로 적합한 키워드를 추출하고 이를 통하여 문서와 유사한 테이블, 문서 내 테이블과 유사한 형식의 테이블을 검색하는 데 적합한 새로운 지능형 테이블 검색 시스템을 제안하며 이를 통해 기존에 존재하는 테이블 검색 시스템 알고리즘들과 성능 비교를 통해 향후 테이블 기반 검색 시스템 발전 가능성을 제시한다.

True process collaboration can be accomplished through seamless integration of business processes and enterprise knowledge. Therefore, it is natural that the concept of Business Operating System (BOS), proposed by Delphi Group in 1994, is currently considered as a next evolutionary step for Business Process Management System (BPMS). Literature reports very little work, however, especially, on a comprehensive architecture of the system. This paper proposes an architecture of BOS with the following definition: ' BOS is an intelligent activity supporting system that provides a comprehensive and personalized work environment to each knowledge-intensive worker. ' To propose an architecture of BOS, the paper first identifies and classifies functional requirements for Business Operating System. Then, it proposes a data model and an architecture of the system to satisfy the functional requirements. The proposed architecture focuses on two essential technical requirements. First, the system should provide an effective means to integrate data and processes and to standardize distributed component systems. Secondly, the system should also be intelligent enough to assist workers to perform their knowledge-intensive work. The paper shows how these requirements can be achieved by using Semantic Web and Web Service.

A model of an assessment module has been created, using intuitionistic fuzzy estimations, which render account on the knowledge of the trained objects. The final mark is determined on the basis of a set of evaluation units. An opportunity is offered no only fur tracing the changes of the parameters of the trainer object, but there is also an opportunity of tracing the status of the already comprehended knowledge, as well as evaluating and changing the training themes and evaluation criteria.

Ubiquitous computing environment, as a new paradigm of the digital information era, has been introduced to respond to rapid changes in society and culture. Today, technology research around the world competes for the preoccupancy of the core technology as well as the development of technology for providing context aware system more intelligent, more sophisticated. Research in recent is underway the implementation of intelligent provisioning system using the ontology. Erstwhile provisioning system did not providing a personalized service that provides the service after context aware. Accordingly, there is a need for studies of intelligent context aware provisioning technique considering environments and context necessary to user. In this paper, in order to provide a service that is optimized for the needs of the user, propose an ontology-based intelligent provisioning service method taking into account the usage patterns and the context of the user. The proposed system is recognized the status of the user and demonstrated a process of reasoning techniques for fit service. And it is possible to the expansion of intelligence.

Over the last few years knowledge management has become more and more impotant part of the in healthcare practices. Therefore the healthcare organisatiions have also begun to apply knowlege management strategies. To address this issue of the lack of true knowledge management in healthcare enterprises, we propose a framework for common Healthcare Knowledge Management. This framework is made up of two suites of applications and services, i.e. the intelligent agent-based knowledge management application suite and the strategic visualisation, planning and coalition formation service suite.
