Öğe A safety food consumption mobile system through semantic web technology(IEEE, 2014) Çelik, Duygu; Elçi, Atilla; Akçiçek, Rıdvan; Gökçe, Bora; Hürcan, Pelin; Chang, CK; Gao, Y; Hurson, A; Matskin, M; McMillin, B; Okabe, Y; Seceleanu, C; Yoshida, KOver 3,000 compounds are being added to processed food. These compounds have numerous effects on food: add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so on. According to a recent report by the World Health Organization, governments have lately focused on legislation to reduce such ingredients or compounds in manufactured foods for they might have side effects causing health risks such as the heart disease, cancer, diabetes, allergens, obesity, etc. Safety in food consumption especially by patients of risk groups have become crucial for such health problems are in the top ten ranked health risks around the world. By supervising what and how much to eat as well as what not to eat, we can maximize a patient's life quality by avoiding unhealthy ingredients or compounds. In helping patients take control of their safe food consumption, we need smart personal e-health systems. Smart personal e-health systems with advanced knowledge management technology can provide suggestions of food appropriate for consumption by individuals. Accessing annotations in the ontology knowledgebase of food appropriate to their personal health condition can be provided. This article discusses one such software application, namely the Safety Food Consumption Mobile System, employing Semantic Web Technology.Öğe An ontology-based information extraction approach for résumés(2013) Çelik, Duygu; Elçi, AtillaA Curriculum Vitae (CV) or a résumé, in general, consists of personal information, education information, work experience, qualifications and preferences parts. Scanning or making structural transformation of the millions of free-formatted résumés from the databases of companies / institutions with human factor will result in the loss of too much time and human effort. In the literature, a limited number of studies have been done to change the résumés of the free-format to a structural format. The overall objective of the study is to infer required information such as user's experience, features, business and education from résumés of the potential user of a human resources system. In this article, we proposed an ontology driven information parsing system that is planned to operate on few millions of résumés to convert them structured format for the purpose of expert finding through the Semantic Web approach. © 2013 Springer-Verlag.Öğe Educational activity discovery system for individuals with pervasive developmental disorders through web ontology language (OWL)(Turkish Education ASSOC, 2014) Çelik, Duygu; Elçi, Atilla; İnan, Necati; Elverici, Eray; Elçi, AlevToday, experts and organizations dealing with pervasive developmental disorder are trying to minimize the experienced problems of the individuals with educational methods chosen carefully after extensive research. However, because of various reasons the relatives of the individuals who cannot reach these organizations are trying to give proper education at home. During these trainings while selecting the educational methods they prefer internet and related software. However, today's static based internet and related software can be insufficient to supple desired result for the individual's needs. In this article, the architecture of Agent-based Educational Activity Discovery System which can operate on semantic base and propose educational methods for parents, pre-school educators, experts that are working for these institutions, university students studying in related fields or individuals interested in pervasive developmental disorder is presented. The ontology knowledgebase of this system is developed by using the OWL (Web Ontology Language) while creating its entire concepts, features, and relations between these concepts about pervasive developmental disorders are defined in ontology.Öğe Message from the ESAS 2015 workshop organizers(IEEE Computer Society, 2015) Elçi, Atilla; Çelik, Duygu[No abstract available]Öğe Message from the workshop organizers: ESAS 2013(2013) Çelik, Duygu; Elçi, Atilla; Orgun, Mehmet A.; Rahnama, Behnam; Unland, Rainer[No abstract available]Öğe Mobile pediatric consultation and monitoring system through semantic web technology(IEEE, 2014) Çelik, Duygu; Elçi, Atilla; Akçiçek, Rıdvan; Gökçe, Bora; Hürcan, Pelin; Chang, CK; Gao, Y; Hurson, A; Matskin, M; McMillin, B; Okabe, Y; Seceleanu, C; Yoshida, KmHealth is a popular aspect of eHealth applications that is starting to explode exponentially. The use of technology offering solutions with a potential of making patients' lives easier in the health sector has gradually increased with mHealth. Technology has great bearing in the health sector in order to increase the efficiency to serve patients by helping to diagnose ailments reliably. Mobile systems help observation of child patients in their treatment process and the collection of health data on the course. Therefore, people will be more aware of their children's health problems and preventive measures in accordance with those health problems. This article is on Mobile Pediatric Consultation and Monitoring System (mPCMS). Details of design and operation are given in this article. mPCMS not only will assist doctors but also help patients in decision making process of the medical treatment due to the information's ease use. Accordingly, with mPCMS, there will be a contribution to distant consultation by the doctor and the family by collecting the health data before and after the treatment of child patients.Öğe Semantic composition of business processes using Armstrong's Axioms(Cambridge University Press, 2014) Çelik, Duygu; Elçi, AtillaLack of sufficient semantic description in the content of Web services makes it difficult to find and compose suitable Web services during analysis, search, and matching processes. Semantic Web Services are Web services that have been enhanced with formal semantic description, which provides well-defined meaning. Due to insertion of semantics, meeting user demands will be made possible through logical deductions achieving resolutions automatically. We have developed an inference-based semantic business process composition agent (SCA) that employs inference techniques. The semantic composition agent system is responsible for the synthesis of new services from existing ones in a semi-automatic fashion. SCA System composes available Web Ontology Language for Web services atomic processes utilizing Revised Armstrong's Axioms (RAAs) in inferring functional dependencies. RAAs are embedded in the knowledge base ontologies of SCA System. Experiments show that the proposed SCA System produces process sequences as a composition plan that satisfies user's requirement for a complex task. The novelty of the SCA System is that for the first time Armstrong's Axioms are revised and used for semantic-based planning and inferencing of Web services.Öğe The 9th IEEE International Workshop on Engineering Semantic Agents - Semantics, Agents and Intelligence (ESAS 2014)(Institute of Electrical and Electronics Engineers Inc., 2014) Elçi, Atilla; Çelik, Duygu; Orgun, Mehmet Ali; Rahnama, Behram; Unland, Rainer[No abstract available]Öğe Towards an ınformation extraction system based on ontology to match resumes and jobs(2013) Çelik, Duygu; Karakaş, A. Aşkın; Bal, Gülşen; Gültunca, Cem; Elçi, Atilla; Buluz, Başak; Alevli, Murat CanWhile Internet takes up by far the most significant part of our daily lives, finding jobs/employees on the Internet has started to play a crucial role for job seekers and employers. Online recruitment websites and human resources consultancy and recruitment companies enable job seekers to create their résumé, a brief written formal document including job seeker's basic information such as personal information, educational information, work experience and qualifications in order to find and apply for desirable jobs, whereas they enable companies to find qualified employees they are looking for. However résumés may be written in many ways that make it difficult for online recruitment companies to keep these data in their relational databases. In this study, a project that Kariyer.net (largest online recruitment website in Turkey) and TUBITAK (The Scientific and Technological Research Council of Turkey) have been jointly working is proposed. In this mentioned project, a system enables free structured format of résumés to transform into an ontological structure model. The produced system based on ontological structure model and called Ontology based Résumé Parser (ORP) will be tested on a number of Turkish and English résumés. The proposed system will be kept in Semantic Web approach that provides companies to find expert finding in an efficient way.Öğe Web ontoloji dili (OWL) yoluyla gelişimsel bozukluğu olan bireylere yönelik eğitsel etkinlik keşif sistemi(Türk Eğitim Derneği, 2014) Çelik, Duygu; Elçi, Atilla; İnan, Necati; Elvereci, Eray; Elçi, AlevGünümüzde, yaygın gelişimsel bozukluğa sahip bireylerin topluma kazandırılmasıyla ilgilenen kurumlar veya uzman eğitim kadrosu, uzun araştırmalar sonunda titizlikle seçtikleri eğitsel metotlarla yaşanılan sıkıntıları aza indirgemeye çalışmaktadırlar. Ancak, pek çok nedenden ötürü, bu kuruluşlara gidemeyen birey yakınları, uygun eğitimi evde vermeye çalışmaktadır. Bu eğitimler sırasında, kullanabilecekleri eğitsel metodu seçerken, internet veya ilgili yazılımlar en sık başvurdukları yöntemlerdendir. Ne var ki şu an statik tabanda sözdizimsel arama yapabilen günümüz internet veya ilgili yazılımları, bireyin ihtiyacına yönelik anlamsal tabanda hizmet/eğitsel aktivite taramalarında istenilen sonucu vermekte yetersiz kalabilmektedir.
