“…OntoES (ML-OntoES) is the initial proposal for an extraction system that supports extraction from two languages, namely, English and Japanese. 18 This system is based on Ontos extraction engine, which is capable of extracting information from semistructured data sources. It uses an object-oriented model to store the ontology, with the extraction rules embedded in the ontology itself.…”

“…For structured content such as tables, table headers are mapped to concepts or concept attributes, and rows are mapped as instances of concepts or values of attributes. 18 For unstructured content like paragraph text, rule-based, pattern matching, and ML approaches are commonly followed. 39 We classify relations between entities into two main categories based on the complexity of the relationships: simple and complex.…”

In order to achieve the vision of the semantic Web, it is important to have enough amount of semantic content on the Web sources. To produce the semantic content on the existing Web, semantic annotation of the Web sources is required. Semantic annotation adds machine-readable content to the Web sources. Because the Web is growing at an exponential rate, semantic annotation by hand is not possible. In this paper, we present an Automatic Semantic Annotation Framework (ASAF) for semantic annotation of Arabic Web sources based on the domain ontologies. We present a learning approach that utilizes public Arabic resources, such as Wikipedia and WordNet for building Arabic ontologies. Moreover, we present different approaches for extracting name entities and relationships from Arabic Web sources. As a case study, we have developed and expanded a set of Arabic ontologies related to food, health, and nutrition through a set of processes. We have also developed the ASAF prototype, and showed how it can utilize these ontologies for extracting health, food related name entities, and relationships from the Web sources in order to annotate and store them in the knowledge-base. We conducted several experiments to test the capability of ASAF in recognizing the name entities and relationships using different approaches. Empirical evaluations of ASAF show promising performance results in terms of precision, recall, and F -measure. The outcome of the presented framework could be utilized by semantic Web searching applications to retrieve precise answers to the end user smarter queries. An important feature of ASAF is that it could be ported to other domains with minimal extension. ASAF also contributes to the vision of the semantic Web in the target domains in Arabic Web sources.

“…Hence the epistemological and linguistic problem: Can we create a system to allow a user to query in language L 1 for facts in a web page written in language L 2 ? We propose a suite of multilingual extraction ontologies as a solution to this problem [13]. We ground extraction ontologies in each language of interest, and we map both the data and the metadata via the language-specific extraction ontologies through a central, language-agnostic ontology, reifying our ontological commitment to cross-linguistic information extraction in a particular domain.…”

Abstract. The synergism among the traditional disciplines of ontology, epistemology, logic, and linguistics and their potential for enhancing conceptual-modeling applications is not fully understood. Better understanding how to adapt ideas from these disciplines should lead to improved serviceability of conceptual modeling. We argue in this position paper, however, that application objectives, rather than philosophical tenets, should guide the adaptation of ideas from these disciplines. Thus, an appropriate balance of discipline-based theory and pragmatism should temper adaptations. We evaluate the principled pragmatism we advocate by presenting several case-study examples. Each illustrates that an appropriate adaptation of ideas from the disciplines of ontology, epistemology, logic, and linguistics can significantly guide conceptual-modeling research and help build successful conceptual-modeling applications.

“…Furthermore, we adopt a multifaceted engineering approach for cross-language mappings, and while recognizing the equivalency problem, we allow for various types of correspondence beyond one-to-one mappings (Embley et al 2011c). We note, however, that the technologies for our system at present originate from the conceptual-modeling and data-extraction communities rather than from natural language processing and computational linguistics, though we foresee being able to orient our work more toward the nexus of all of these areas.…”

“…What distinguishes our approach is the narrow, domain-specific, user-definable nature of our ontologies and their construction, as well as the role of these ontologies at the center of a larger infrastructure (Embley et al 2011c). Our ontologies tend to be less elaborate than others and hence less rich in the types of context required for successful treatment by statistical translation methods.…”

Similarly, not enough evidence exists with regard their role as contributors to multilingual web accessibility. This paper presents the initial results of a study carried out with the goal of clarifying localisers' involvement in the achievement of web accessibility. Data gathered suggest that (1) localisation experts should have web accessibility knowledge as part of their skills set; and that (2) localisers' participation in multilingual web assessment for accessibility would be of added-value for evaluators. RESUM (Cap a una definició del paper del localitzador en la consecució de llocs web multilingües més accessibles) Tenir coneixements sobre accessibilitat no constitueix habitualment un requisit per a desenvolupar tasques de localització de forma professional. D'igual manera, existeix poca informació sobre el paper que podria tenir el localitzador en la consecució d'una web més accessible. Les dades incloses en aquest article, recollides a partir d'una enquesta realitzada a experts en accessibilitat web indiquen que (1), els localitzadors haurien d'adquirir coneixements sobre accessibilitat com a part de la seva formació i que (2), les seves competències professionals podrien de ser rellevants durant l'avaluació de l'accessibilitat web de llocs web multilingües.
