Semi-automatic construction of a domain ontology for wind energy using Wikipedia articles

Domain ontologies are important information sources for knowledge-based systems. Yet, building domain ontologies from scratch is known to be a very labor-intensive process. In this study, we present our semi-automatic approach to building an ontology for the domain of wind energy which is an important type of renewable energy with a growing share in electricity generation all over the world. Related Wikipedia articles are first processed in an automated manner to determine the basic concepts of the domain together with their properties and next the concepts, properties, and relationships are organized to arrive at the ultimate ontology. We also provide pointers to other engineering ontologies which could be utilized together with the proposed wind energy ontology in addition to its prospective application areas. The current study is significant as, to the best of our knowledge, it proposes the first considerably wide-coverage ontology for the wind energy domain and the ontology is built through a semi-automatic process which makes use of the related Web resources, thereby reducing the overall cost of the ontology building process.


A domain framework approach offering default relations
Kargı, Ersin Eray; Doğru, Ali Hikmet; Department of Computer Engineering (2005)
In order to use components that are developed for a domain, domain knowledge is required. If the default relations in a domain are offered by a framework, this can be a starting point for the application engineer as an important kind of domain knowledge. A generic design for creating and saving a domain is implemented in this thesis. This approach starts with creating a domain from components and relations among these components. The relations and components are saved once and used several times. In additio...
Evaluating the mine plan alternatives with respect to bottom-up and top-down sustainability criteria
Yaylaci, Evren Deniz; Düzgün, Hafize Şebnem (Elsevier BV, 2017-11-20)
The previous researches on sustainability evaluation for the mining sector indicate that the tailor-made integrated frameworks should have the capabilities of integrating the stakeholder-focused information as effectively as operational information into the evaluation and reporting process. In this regard, this paper proposes an indicator-based quantitative evaluation framework for integrating the concerns and priorities of the local stakeholders into the evaluation of sustainability in the mining sector op...
One-year performance evaluation of two newly developed back-contact solar modules in two different climates

To a certain extent, the photovoltaics industry is well developed, and the performance and expected yield of standard photovoltaic modules are well documented and researched. However, newer more efficient photovoltaic cell and module technologies are being developed all over the world. Outdoor testing of new photovoltaic technologies is very important to understand and validate their reliability and performance under different environmental conditions. For the first time, one year of monitored performance d...
Employing Machine Learning Techniques for Data Enrichment: Increasing the number of samples for effective gene expression data analysis
Erdogdu, Utku; TAN, MEHMET; Alhajj, Reda; Polat, Faruk; Demetrick, Douglas; Rokne, Jon (2011-11-15)
For certain domains, e. g. bioinformatics, producing more real samples is costly, error prone and time consuming. Therefore, there is a need for an intelligent automated process capable of substituting the real samples by artificial samples that carry the same characteristics as the real samples and hence could be used for running comprehensive testing of new methodologies. Motivated by this need, we describe a novel approach that integrates Probabilistic Boolean Network and genetic algorithm based techniqu...

The integrated intensity of the central peak is calculated as a function of temperature in the ferroelectric phase (T < T-C) of nearly stoichiometric LiTaO3. This calculation is performed using the temperature dependence of the order parameter obtained from the mean field theory at temperatures lower than the transition temperature T-C (T-C = 963 K) of this crystal. The calculated values of the order parameter (squared) are fitted to the integrated intensity of the central peaks as observed from the Raman a...
