The purpose of designing a corporate memory within an industrial-based organization is to facilitate user access to critical knowledge held in this memory. So, the objective of corporate semantic web service architecture that we propose is to include knowledge in domain ontology and to make them easily accessible by users. In our context, knowledge contained in the ontology concerns industrial medical...
Event-based online social networks are Internet-based services that enable users to participate in real world experiences together. Event-based social networks can be created by a community of end-users based on their own interests in specific types of event and sources of event information. We propose a method to create such event-based social networks through integration of existing online information...
Data and information about Indonesian genetic resources and traditional knowledge, especially the current data on medicinal plants is not managed optimally yet. The data and information is still scattered which if there is no integrated management action done, the data and information might be lost. One effort to integrate the data about medicinal plants is by building the ontology. This research...
Semantic models of data sources describe the meaning of the data in terms of the concepts and relationships defined by a domain ontology. Building such models is an important step toward integrating data from different sources, where we need to provide the user with a unified view of underlying sources. In this paper, we present a scalable approach to automatically learn semantic models of a structured...
The Internet of Things refers to extending the Internet to physical entities of interest (EoI) to humans (e.g. a table, a room or another human being) sensed as a set of properties that can be observed, measured, accessed or triggered by devices such as actuators, sensors or other smart components. In this vision, the IoT foresees novel types of applications dynamically finding the associations between...
Automated service composition is critical for successfully implementing Building Automation Systems which facilitate Web services over physical devices. In this paper, we propose a new service composition model using a policy ontology represented by Semantic Web languages. Our proposed model can be a powerful tool to automatically compose services with associating meaningful policies.
Object reconstruction is an important task in many fields of application as it allows to generate digital representations of our physical world used as base for analysis, planning, construction, visualization or other aims. A reconstruction itself normally is based on reliable data (images, 3D point clouds for example) expressing the object in his complete extent. This data then has to be compiled...
Topic Maps are a Semantic Web technology for semantic annotation of resources to enhance the quality of search output. Manual development of topic maps is a difficult and time consuming task. Furthermore, there are many relational databases with valuable data that semantic search methods cannot use them. To solve this problem, this paper proposed a novel automatic approach to generate topic map from...
While ontology is critical to realize semantics, many defects exist in its building methods, especially conflicts between building cost and ontology quality. Specific to this problem, the paper brings forward an automatic ontology building method grounded on case-base. That is, to build domain ontology automatically with field concepts and relations extracted from case-base which records a plenty...
The proposal and development of semantic web make ontology, as a new knowledge organization and semantic description method, get attention in various fields. The building of ontology is a basic and important task in semantic web. The construction method and organizational structure of ontology will directly affect the application of ontology. Based on the analysis of hierarchical characters existing...
This paper focuses on the building of basic conditions for the Korean cultural heritage ontology structure by using CIDOC CRM (ICOMs International Committee for Documentation Conceptual Reference Model). Issues with using the CIDOC CRM have been raised in other countries, such as Finland, the Netherlands, and the United Kingdom. Heritage information structures on the web in Korea are analyzed. In...
The incredible amount of web information and the inhumane retrieval result from search engine cannot satisfy people's demands. Reorganizing the web information in hierarchical structure is one solution. To achieve this aim the knowledge base on specific domain is built using ontology technology. The definition of event which is composed by key information and attributes is given to match the knowledge...
Building ontologies is very important for diverse domains and especially for semantic Web. We find in the literature many methods and tools for this building. However, the fuzzy aspect is not enough studied in these methods and tools, whereas information systems can include uncertainties and imperfections. The goal of the definition of fuzzy ontologies is to integrate these characteristics. So, we...
Semantic Web has reached the point where basic research is supposed to be replaced (at least partially) by research aiming at practical aspects of using the Semantic Web. Ontologies, as the essential technology in this area, have been under the spot light which produced some results, e.g. the Semantic Web Search engines like Watson, Swoogle etc. These help in finding and locating semantic information...
“SeMoDesk” is an approach to implement the Semantic Desktop on mobile devices. The idea is to allow users to manage their personal information space using personal ontologies. In this paper, we are presenting our solution to improve location-awareness in this scenario. We have designed a location and sensor ontology as an extension to the personal ontology. This ontology is then used to retrieve relevant...
