The paper concentrate on the development of an innovative robotic system based on ontologies as knowledge-source used to solve shortcomings of the state-of-the-art solutions. The description of the product in form of ontologies facilitates the autonomous reasoning about the used concepts linking product model, manufacturing process and production infrastructure. By applying our ontology-driven concept,...
Knowledge about system life cycle processes constitutes one of the most valuable assets for systems engineering practitioners. While effective management of processes is imperative, it is an onerous task as knowledge is tacit and implicit. Although best practice to ensure the quality of such processes has been documented in the International Standard ISO/IEC/IEEE 15288, it is limited to human-readable...
Barter system is an alternative commerce approach where customers meet at a marketplace in order to exchange their goods or services without currency. E-barter systems, also gain attention with the rise of e-commerce. Barterers search databases for goods and services they need. In this paper, the integration of ontology and agent systems is proposed as a solution for searching in diverse barter databases...
The development of increasingly complex systems with improved quality levels becomes more and more challenging. Engineering data frameworks with integrated system models have been developed to manage such systems. This paper presents the experiences that have been made in digital systems engineering in the aerospace domain and focuses on the roadmap that has been taken to establish a knowledge engineering...
In Enterprise Modeling, we use several languages for designing, analyzing, and communicating the different domains of an enterprise. Two important criteria for choosing a domainspecific language are its appropriateness to the requirements of the enterprise, as well as the accuracy of the language in describing the domain at hand. However, in some business domains, core concepts --such as Capability,...
Engineering phase specific tailored views on data are required to prevent over-engineering and to discover missing elements. This paper presents an approach to enhance a semantic Conceptual Data Model (CDM) to define the specific behavior of engineering phases. Therefore, a CDM gets enhanced by an ontology profile to specify required and non-admissible features for each engineering phase. This is...
This research proposed a TCM FS Ontology using FS-associated information retrieved from ancient Chinese medical texts. To standardize the process, we rigorously followed the 7-steps-approach proposed by Standard University. Besides, the establishing of axioms constraining the relationships between concepts may provide reference for the construction of knowledge base in future studies.
Medical search technologies are crucial to enable the user to rapidly and effectively discover useful information from massive medical and clinical data. Because of the complexity of medical terminology, traditional information search methods have not fully expressed the intention of the query request and explored the potential semantic knowledge in the document. In this paper, we propose a multi-analysis...
Annotation is the process of adding semantic metadata to resources so that data becomes more meaningful. Creating additional metadata by document annotation is considered one of the main techniques that make machines understand and deal with data on the web. Our paper presents a semantic framework that annotates RSS News Feeds. Semantic Annotation for News Feeds Frameworks (SANF) aims to enrich web...
Automatic essay evaluation (AEE) systems are designed to assist a teacher in the task of classroom assessment in order to alleviate the demands of manual subject evaluation. However, although numerous AEE systems are available, most of these systems do not use elaborate domain knowledge for evaluation, which limits their ability to give informative feedback to students and also their ability to constructively...
The shift from mass production to mass customization has led many manufacturers to diversify their product portfolio by making their products highly configurable. This diversification often results in higher production costs. Through standardization this costs can be reduced. Clustering of sold product configurations can help identify configurations that can be standardized without dissatisfying the...
This article involves the analysis of known ontologies for solving production system management problems. The article considers the tasks solved by the ontological approach. It describes the developed ontology integration at the semantic level of data from databases of different industry information systems to support the management decisions, to use knowledge bases to support the decisions in logistics...
Natural Language Processing (NLP) is one of the principal areas of artificial intelligence. It can be argued that the use of ontologies increases the efficiency of natural language processing. However, most ontologies are built manually and require a lot of work. Thus, the problem of automated ontology replenishment is very relevant. One approach is to develop methods for replenishing ontologies using...
Twitter and social media as a whole has great potential as a source of disease surveillance data however the general messiness of tweets presents several challenges for standard information extraction methods. Current methods for disease surveillance on twitter rely on inflexible keyword based approaches that require messages to be pre-filtered on the basis of a disease name which is supplied a priori...
The word ontology refers to the hierarchical structure of entities and their relationships. The entities are nodes and each node is dominated by their parent node in the hierarchical structure. The nodes are related by semantic and lexical relations such as synonymy, homonymy, meronymy, antonymy, etc. Hierarchical structure is created for different types of semantic domains. The top domains are entities,...
Automatic recommendations based on skill matching techniques can prove to be an important component of an online recruitment platform, being able to lower the costs for employers, ease the process for candidates and increase the hiring quality overall. This is important nowadays, when online recruitment plays a major role in the hiring process. The main challenges in this area consist in providing...
We present a system of services for the automatic processing of collections of scientific documents that are part of digital libraries. These services are based on ontologies for scientific documents representation, as well as on methods for semantic analysis of mathematical documents. The developed tools automatically check validity of documents for compliance with manuscript guidelines, convert...
The explosion of digital data in the last two decades followed by the development of various types of data, including text, images, audio and video known as multimedia data. Multimedia Information Retrieval is required to search various type of media. There is comprehensive information need that can not be handled by the monolithic search engine like Google, Google Image, Youtube, or FindSounds. The...
The Internet of Things (IoT) continues to expand in terms of the number of connected devices. To handle the data produced by those devices, gateways are deployed to collect data, possibly to analyze it, and finally to send it to the cloud or to the end-user to support new services. This process involves complex software that is deployed on those gateways. Moreover, the dynamicity due to new services,...
We live in an increasingly connected and data-greedy world. In the last decade, informative contents over the Web have grown in volume, connectivity and heterogeneity to an extent never seen before. Well known examples of Online Multimedia Social Networks (OMSNs), such as Facebook or Twitter, demonstrate the humongous volume and complexity characterizing common scenarios of the contemporary Web. Recognizing...
