1. Introduction
Domain ontologies are usually defined as collections of semantic concepts describing a domain together with the interrelations among the concepts and rules governing these concepts [1]. A domain ontology is a valuable semantic resource for the underlying domain since it can act as a shared vocabulary for the domain under consideration, it can help reduce possible interoperability problems between the domain-specific applications and Semantic Web applications, in addition to several other uses, as reviewed in studies like [2]. Ontologies have been proposed for several application domains so far, including those ontologies for bioinformatics [3], petri nets [4], chemical process engineering [5], software product families [6], electrical power quality [7], and wind energy [8], among others. Due to the peculiar needs of the applications in which domain ontologies are to be employed, some ontologies should possess fuzzy characteristics. Hence, fuzzy domain ontologies have also been proposed and exploited in several applications. Examples of fuzzy ontology proposals include the ontology in [9] for medical information retrieval, that in [10] for news summarization, and the one in [11] for the acquisition and share of scientific information on the Web. An important issue regarding the construction of domain ontologies is that it is a considerably labor-intensive and time-consuming process which is usually carried out by the experts of the domain. As reviewed in studies like [2,12], there are several studies that target at decreasing the overall cost of the ontology building process through the employment of semi-automatic approaches which involve a learning phase, along the way. Yet, even within such procedures, manual intervention by the domain experts is still indispensable for the validation and extension of the automatically built ontology, hence rendering the approaches semi-automatic. During the ontology building process, significant information sources like Wikipedia [13] can be used, since Wikipedia is a community-created knowledge base known to facilitate several applications as reviewed in [14]. To illustrate, the domain ontology for wind energy is built based on the Wikipedia articles through a semi-automatic process, as described in [8]. In this paper, we propose an ontology for the domain of electrical energy, with weighted attributes, where the engineering process of this ontology is based on Wikipedia as the main information source. The existing ontologies proposed for the corresponding subdomains are aligned with the ultimate ontology whenever applicable. The ontology is mainly proposed to facilitate related text analysis applications and sample applications are implemented to demonstrate the utilization of the ontology and linked ones, in such settings. The main contributions of the current study are summarized below:
