  • A novel diagnosis scheme PCADP(personalized computer aided diagnosis probability) is proposed to overcome the problems mentioned above. PCADP scheme is a personalized diagnosis method based on ontology and it makes the bio-data analysis just a 'process' in the Smart healthcare service system. In addition, we offer a semantics modeling of the smart healthcare ontology framework in order to describe smart healthcare data and service specifications as meaningful representations based on this PCADP. The PCADP scheme is a kind of statistical diagnosis method which has real-time processing, characteristics of flexible structure, easy monitoring of decision process, and continuous improvement.

  • This study suggested knowledge base and search engine for the libraries that have the largescaled data. For this purpose, 3 components of knowledge bases(triple ontology, concept-based knowledge base, inverted file) were constructed and 3 search engines(search engine JENA for rule-based reasoning, Concept-based search engine, keyword-based Lucene retrieval engine) were implemented to measure their performance. As a result, concept-based retrieval engine showed the best performance, followed by ontology-based Jena retrieval engine, and then by a normal keyword search engine.

  • In this study, the experiment was made to transform the relationship among terms in a thesaurus to ontology language as search tools for multilingual text. As a result, the equivalent relationship in the thesaurus can be expressed by different ways in the ontology, such as equivalentClass, equivalentProperty, sameAS, and so on. On the other hand, the associative relationship can be represented by ObjectProperty, DatatypeProperty, and inverseOf. For this test, first of all, the descriptors assigned by AAT and the descriptors from bilingual thesaurus by ICCD were translated into Korean. Then, the facet was used for conceptual equivalence among terms from different languages. The result of the study showed that using rdf:Property in ontology was the most effective way of transforming multilingual thesaurus into ontology.

  • The systematic management of research data is vital because it increases research data's value for research reproduction, verification, and reusability. Standard metadata will play a key role in research data registration, management, and data extraction. Research data has various structural relationships, such as research, research data, data sets, and files, and associated with entities such as citations and research results. The study proposes an ontology model for research data management. It also suggests the application of ontology to NTIS. Previous studies, metadata standard analyses, and research data repository case studies were conducted.

  • Historical-cultural contents are digitized documents of records or evidences about changes of human society. The changes or evolvements are results of the interaction between society and environment. So the different feafures are appears by spatio-temporal observing locations Historical-cultural contents need to be designed so that the preservation and exchange of information, adaptation to changes of the future are easy. So historical-cultural contents have structured to support the intelligent services based on context. This study propose context-based ontology-design method based on events, and we implemented web services of Bible contents by proposed method.

  • The method of recent information retrieval passes into an semantic search to provide more accurate results than keyword-based search. But in common user case, they are still accustomed to using existing keyword-based search. Hence they are hard to create a typed structured query language. In this paper, we propose to ontology knowledge-base scheme for query interpretation of these user. The proposed scheme was designed based on the OWL-DL for description logic reasoning, it can provide a richer representation of the relationship between the object by using SWRL(Semantic Web Rule Language). Finally, we are describe the experimental results of the similarity measurement for verification of a user query semantic interpretation.

  • Context-awareness as a key technology of ubiquitous computing needs a context model that understands and processes situational information coming from diverse sensors and devices, and can be applied diversely in various domains. Semantic web based ontologies use structured standard format and express meaning of information, so it is possible to recognize effectively context-awareness situations, allowing the system to share information and understand situation by inference. In this paper, we propose a layered ontology model to support generality and scaleability of the context-awareness system, and applied the model to u-Convention domain. In addition, we propose a effective reasoning method to handle compound situation by combining OWL-DL and SWRL rules.

  • Diverse researches such as referring to classical literature for liberal arts courses, transformation of classical literature into cultural content and understanding classical literature through digital media have been engaged in an effort to spread the diachronic value of classical literature to the public in general, which should be based on clear understanding of authorship of classical literature. Thus this study aims to design ontology in order to establish knowledge structure of classical literature. For this purpose, the BIBFRAME model and OWL have been utilized while a variety of classical literature and related studies have been analyzed. This led to 19 classes of Work, Instance, Authority, and Annotation, instance, each of which has been provided with property and indexing examples. The classical literature ontology designed through this study is expected to serve as the foundation for development of a classical literature system in future.

  • 웹의 비약적인 발전으로 정보가 폭발적으로 증가하였고, 이로 인하여 정보검색 기술에서 해당 정보를 빠르게 찾는 것에 목표를 두었던 기술이 원하는 정보를 정확하게 찾는 기술로 발전을 이루게 된다. 시맨틱 웹 기술은 이와 같은 요구에 부응하기 위하여 등장했으며 의미 기반의 검색 및 추론과 같은 지식 발견 등의 기술을 가능하게 한다. 일반적인 정보가 아닌 법률과 같은 전문지식 영역의 정보는 현재 일반 사용자들이 쉽게 접근하여 법률 정보를 확인할 수 있는 환경이 되지 못한다. 따라서 시맨틱 웹 기술을 이용한 온톨로지 기반의 법률 검색 서비스가 필요하며 이를 위한 기반 시스템을 구축하는 것이 중요하다. 따라서 본 논문에서는 온톨로지 기반의 법률 검색 서비스를 위해 법률이 가지는 구조적 특징을 분석하고, RDF 기반의 온토롤지 구축 방법 및 RDF 언어 레벨에서 하지 못했던 명시적인 트리플 외에 추론된 트리플을 찾아 낼 수 있는 질의 방법의 고안 및 추론 방법을 제안한다. 이를 통해 법률 용어를 정확하게 모르는 일반 사용자들이 법과 관련된 검색을 수행할 시 효과적으로 법명 및 조문 내용을 확인할 수 있으며 RDF 언어 레벨의 추론 기능의 제안으로 RDF 레벨로 구축된 다양한 분야의 시스템에서 다른 추가적인 레이어 없이 추론을 위한 기반 기술을 갖출 수 있다.

  • In collaborative environment, since each agent generally uses different words for the same meaning, there is an obstacle for information sharing. In collaborative product development environment, each agent has different words for representing same product information. As a result, it is hard to share product information in this situation. For solving this problem, semantic-based product information is needed. In this paper, a ontology-based semantic searching system which is able to interact with legacy PDM systems is proposed for product information sharing in collaborative environment Product ontology is represented with OWL format, and the product ontology is processed by Pellet reasoning engine for semantic searching. The system is implemented as a web service which can be integrated with other systems. This paper also introduces the approach with which a PDM system provides a function of semantic search with this search system.
