Abstract

Purpose

Ontologies are prone to wide semantic variability due to subjective points of view of their composers. The purpose of this paper is to propose a new approach for maximal unification of diverse ontologies for controversial domains by their relations.

Design/methodology/approach

Effective matching or unification of multiple ontologies for a specific domain is crucial for the success of many semantic web applications, such as semantic information retrieval and organization, document tagging, summarization and search. To this end, numerous automatic and semi-automatic techniques were proposed in the past decade that attempt to identify similar entities, mostly classes, in diverse ontologies for similar domains. Apparently, matching individual entities cannot result in full integration of ontologies’ semantics without matching their inter-relations with all other-related classes (and instances). However, semantic matching of ontological relations still constitutes a major research challenge. Therefore, in this paper the authors propose a new paradigm for assessment of maximal possible matching and unification of ontological relations. To this end, several unification rules for ontological relations were devised based on ontological reference rules, and lexical and textual entailment. These rules were semi-automatically implemented to extend a given ontology with semantically matching relations from another ontology for a similar domain. Then, the ontologies were unified through these similar pairs of relations. The authors observe that these rules can be also facilitated to reveal the contradictory relations in different ontologies.

Findings

To assess the feasibility of the approach two experiments were conducted with different sets of multiple personal ontologies on controversial domains constructed by trained subjects. The results for about 50 distinct ontology pairs demonstrate a good potential of the methodology for increasing inter-ontology agreement. Furthermore, the authors show that the presented methodology can lead to a complete unification of multiple semantically heterogeneous ontologies.

Research limitations/implications

This is a conceptual study that presents a new approach for semantic unification of ontologies by a devised set of rules along with the initial experimental evidence of its feasibility and effectiveness. However, this methodology has to be fully automatically implemented and tested on a larger dataset in future research.

Practical implications

This result has implication for semantic search, since a richer ontology, comprised of multiple aspects and viewpoints of the domain of knowledge, enhances discoverability and improves search results.

Originality/value

To the best of the knowledge, this is the first study to examine and assess the maximal level of semantic relation-based ontology unification.

Abstract

Purpose

Leading-edge information and communication technology provides the base to facilitate obtaining, interoperating and federating shared metadata knowledge in collaborative networks from multiple heterogeneous data sources. The purpose of this study is to develop a methodology and a set of mechanisms to support this task in the collaborative environment.

Design/methodology/approach

In this paper, the authors first identify and capture four main typical sources to find or generate metadata knowledge for shared data in emerging networked environments, including existing well-designed metadata, the typical ones are relational schemas of existing databases in the environment; fragmented metadata sources, i.e. metadata that can be realized from existing mission statements and example application scenarios in the environment, usually characterized by their fragmented, lightweight and behavior-intensive features; extracting metadata for simple labeled unstructured data, e.g. textual communications among its stakeholders; and semantic constraints on metadata, e.g. the temporal data behavior could be generated from governance policies in the environment. Second, the authors introduce their systematic methodology to the unification of the resulted metadata consisting of four semiautomated unification steps that gradually develops and enhances a unified ontology for the environment, formalized in web ontology language.

Findings

The methodology steps and their corresponding mechanisms are described and exemplified in detail in this paper. Furthermore, this paper presents the outcome of applying the authors’ methodology to an example emerging case through the generation of a unified ontology for that environment.

Originality/value

The addressed example application area is a real case in the field of higher education in China and therefore serves as a proof of concept and verification of the effectiveness of the authors’ proposed approach.

Abstract

Purpose

The purpose of this paper is to merge the ontologies that remove the redundancy and improve the storage efficiency. The count of ontologies developed in the past few eras is noticeably very high. With the availability of these ontologies, the needed information can be smoothly attained, but the presence of comparably varied ontologies nurtures the dispute of rework and merging of data. The assessment of the existing ontologies exposes the existence of the superfluous information; hence, ontology merging is the only solution. The existing ontology merging methods focus only on highly relevant classes and instances, whereas somewhat relevant classes and instances have been simply dropped. Those somewhat relevant classes and instances may also be useful or relevant to the given domain. In this paper, we propose a new method called hybrid semantic similarity measure (HSSM)-based ontology merging using formal concept analysis (FCA) and semantic similarity measure.

Design/methodology/approach

The HSSM categorizes the relevancy into three classes, namely highly relevant, moderate relevant and least relevant classes and instances. To achieve high efficiency in merging, HSSM performs both FCA part and the semantic similarity part.

Findings

The experimental results proved that the HSSM produced better results compared with existing algorithms in terms of similarity distance and time. An inconsistency check can also be done for the dissimilar classes and instances within an ontology. The output ontology will have set of highly relevant and moderate classes and instances as well as few least relevant classes and instances that will eventually lead to exhaustive ontology for the particular domain.

Practical implications

In this paper, a HSSM method is proposed and used to merge the academic social network ontologies; this is observed to be an extremely powerful methodology compared with other former studies. This HSSM approach can be applied for various domain ontologies and it may deliver a novel vision to the researchers.

Originality/value

The HSSM is not applied for merging the ontologies in any former studies up to the knowledge of authors.

Abstract

There are the interesting words of Myrdal in respect of the universality and commonness of what a scientific problem means:From then on more definitely I came to see that in reality there are no economic, sociological, psychological problems, but just problems and they are all mixed and composite. In research the only permissible demarcation is between relevant and irrelevant conditions. The problems are regularly also political and have moreover to be seen in historical perspective.

Abstract

Purpose

One key issue of maintaining Web information systems is to guarantee the consistency of their knowledge base, in particular, the rules governing them. There are currently few methods that can ensure that rule bases management can scale to the amount of knowledge in these systems environment.

Design/methodology/approach

In this paper, the authors propose a method to detect correct dependencies between rules. This work represents a preliminary step for a proposal to eliminate rule base anomalies. The authors previously developed a method that aimed to ameliorate the extraction of rules dependency relationships using a new technique. In this paper, they extend the proposal with other techniques to increase the number of extracted rules dependency relationships. The authors also add some modules to filter and represent them.

Findings

The authors evaluated their own method against other semantic methods. The results show that this work succeeded in extracting better numbers of correct rules dependency relationships. They also noticed that the rule groups deduced from this method’s results are very close to those provided by the rule bases developers.

Originality/value

This work can be applied to knowledge bases that include a fact base and a rule base. In addition, it is independent of the field of application.

Abstract

Purpose

To address the much heated debate now raging in the international scene, namely between Islam and the West as two great civilization forces of mankind.

Design/methodology/approach

The objective is achieved by studying it in the light of rigorous analysis involving the world‐systems of the two paradigms and by subjecting the analysis to mathematical investigation as necessary.

Findings

Some specific issues, such as epistemology and the associated phenomenological model, its application for economy, markets, money and globalization are investigated to establish the arguments of the paper.

Research limitations/implications

If research is reported on in the paper this section must be completed and should include suggestions for future research and any identified limitations in the research process.

Practical implications

Some practical implications arising from the theoretical basis of the paper are shown in the areas of money and real economy, globalization and the economy.

Originality/value

Such a contrasting scientific argumentation between Islam and neoliberalism as the contrasting paradigms has not been undertaken in any paper that I know of. Thus, this is an original paper in argumentation rather than polemics.

Abstract

In this paper, I compare Theodore Schatzki’s practice theory, the existential phenomenology of Martin Heidegger upon whom Schatzki drew in its formation, and my own theory of institutional logics which I have sought to develop as a religious sociology of institution. I examine how Schatzki and I both differently locate our thinking at the level of practice. In this essay I also explore the possibility of appropriating Heidegger’s religious ontology of worldhood, which Schatzki rejects, in that project. My institutional logical position is an atheological religious one, poly-onto-teleological. Institutional logics are grounded in ultimate goods which are praiseworthy “objects” of striving and practice, signifieds to which elements of an institutional logic have a non-arbitrary relation, sources of and references for practical norms about how one should have, make, do or be that good, and a basis of knowing the world of practice as ordered around such goods. Institutional logics are constellations co-constituted by substances, not fields animated by values, interests or powers.

Because we are speaking against “values,” people are horrified at a philosophy that ostensibly dares to despise humanity’s best qualities. For what is more “logical” than that a thinking that denies values must necessarily pronounce everything valueless? Martin Heidegger, “Letter on Humanism” (2008a, p. 249).

Abstract

Purpose

The purpose of this paper is to answer the question posed in the literature: “What is the definition of law and justice?”

Design/methodology/approach

The paper addresses the question from the vantage point of contrasting epistemological premises of liberalism and unity of knowledge.

Findings

Only the epistemology of unity of knowledge can answer the question as posed above. Rationalism and liberalism are unable to answer this question.

Research limitations/implications

The empirical section could be elaborated further, but this is beyond the scope of the paper.

Practical implications

The paper opens up a vista of applications in the area of institutional change and the moral and ethical edicts of law and justice for purposes of intellection and application.

Originality/value

The epistemological inquiry under unity of knowledge has answered the otherwise impending quest for an answer to the question that has remained unanswered.

Abstract

The ontological‐epistemological relevance of Divine Unity at the core of socio‐scientific world‐systems is developed in analytical terms and is contrasted with the scientific roots of rationalism. The versatile capability of the unity world view is seen to explain both truth and falsehood in a scientific sense. Unification is treated as the application of the knowledge flows emanating from the ontology‐epistemology of fundamental unity to world‐systems. Thus, a comprehensive theorem relating to the knowledge‐centred world view is developed and proved.

The purpose of this paper is to develop a general framework that incorporates collaborative social tagging with a novel ontology scheme conveying multiple perspectives.

Abstract

Purpose

The purpose of this paper is to develop a general framework that incorporates collaborative social tagging with a novel ontology scheme conveying multiple perspectives.

Design/methodology/approach

This paper proposes a framework where multiple users tag the same object (an image in this case) and an ontology is extended based on these tags while being tolerant of different points of view. Both the tagging and the ontological models are intentionally designed to suit the multi‐perspective environment. The paper develops a method based on a set of rules that determine how to associate new concepts to predefined perspectives (in addition to determining relations to topics or other concepts as typically done in previous research) and how to insert and maintain multiple perspectives.

Findings

This case study experiment, with a set of selected annotated images, indicates the soundness of the proposed ontological model.

Originality/value

The proposed framework characterises the underlying processes for controlled collaborative development of a multi‐perspective ontology and its application to improve image annotation, searching and browsing. The significance of this research is that it focuses on exploring the impact of creating a constantly evolving ontology based on collaborative tagging. The paper is not aware of any other work that has attempted to devise such an environment and to study its dynamics.
