Abstract

Purpose

The purpose of this paper is to introduce a novel framework for visual-aided ontology-based multidimensional ranking and to demonstrate a case study in the academic domain.

Design/methodology/approach

The paper presents a method for adapting semantic web technologies on multiple criteria decision-making algorithms to endow to them dynamic characteristics. It also showcases the enhancement of the decision-making process by visual analytics.

Findings

The semantic enhanced ranking method enables the reproducibility and transparency of ranking results, while the visual representation of this information further benefits decision makers into making well-informed and insightful deductions about the problem.

Research limitations/implications

This approach is suitable for application domains that are ranked on the basis of multiple criteria.

Originality/value

The discussed approach provides a dynamic ranking methodology, instead of focusing only on one application field, or one multiple criteria decision-making method. It proposes a framework that allows integration of multidimensional, domain-specific information and produces complex ranking results in both textual and visual form.

Abstract

Purpose

The purpose of this study is to analyze from multiple perspectives, so as to form an effective massive open online course (MOOC)personalized recommendation method to help learners efficiently obtain MOOC resources.

Design/methodology/approach

This study introduced ontology construction technology and a new semantic association algorithm to form a new MOOC resource personalized recommendation idea. On the one hand, by constructing a learner model and a MOOC resource ontology model, based on the learner’s characteristics, the learner’s MOOC resource learning preference is predicted, and a recommendation list is formed. On the other hand, the semantic association algorithm is used to calculate the correlation between the MOOC resources to be recommended and the learners’ rated resources and predict the learner’s learning preferences to form a recommendation list. Finally, the two recommendation lists were comprehensively analyzed to form the final MOOC resource personalized recommendation list.

Findings

The semantic association algorithm based on hierarchical correlation analysis and attribute correlation analysis introduced in this study can effectively analyze the semantic similarity between MOOC resources. The hybrid recommendation method that introduces ontology construction technology and performs semantic association analysis can effectively realize the personalized recommendation of MOOC resources.

Originality/value

This study has formed an effective method for personalized recommendation of MOOC resources, solved the problems existing in the personalized recommendation that is, the recommendation relies on the learner’s rating of the resource, the recommendation is specialized, and the knowledge structure of the recommended resource is static, and provides a new idea for connecting MOOC learners and resources.

Abstract

Purpose

The purpose of this paper is to review recent developments in educational informatics relating to the provision by information systems of pedagogical support to web‐based learners, and to propose further investigation of the feasibility and potential value of web‐based “conversational” information systems to complement adaptive hypermedia and information retrieval systems.

Design/methodology/approach

The potential of Pask's conversation theory is considered as a potentially useful framework for the development of information systems capable of providing pedagogical support for web‐based learners, complementary to that provided by existing computer‐assisted learning and adaptive hypermedia systems. The potential role and application of entailment meshes are reviewed in relation to other forms of knowledge representation including classifications, semantic networks, ontologies and representations based on knowledge space theory.

Findings

Concludes that conversation theory could be a useful framework to support the development of web‐based “conversational” information that would complement aspects of computer‐assisted learning, adaptive hypermedia and information retrieval systems. The entailment mesh knowledge representation associated with conversation theory provides the potential for providing particularly rich pedagogical support by virtue of its properties of cyclicity, consistency and connectivity, designed to support deep and enduring levels of understanding.

Research limitations/implications

Although based on a considerable body of theoretical and empirical work relating to conversation theory, the paper remains speculative in that the gap is still great between, on the one hand, what has so far been achieved and, on the other, the practical realisation of its potential to enhance web‐based learning. Much work remains to be done in terms of exploring the extent to which procedures developed and benefits found in relatively small‐scale experimental contexts can effectively be scaled to yield enhanced support for “real world” learning‐related information behaviour.

Originality/value

The ideas of Pask, discussed in this paper, are capable of guiding the structuring of information according to parameters designed to facilitate deep and enduring understanding via interactive “conversational” engagement between the conceptual structures of information source authors and learners. If one can scale Pask's work to “real world” learning‐related information behaviour, one can increase the range of web‐based information systems and services capable of providing pedagogical support to web‐based learners.

Abstract

How can an author verify that his writing says what he means and means what he says? Authoring systems are generally specialized in document content creation and pay little attention to techniques for making communicative intentions more explicit. The new idea defended here is that the authors of technical or educational documents can improve access to, comprehension and reuse of documents, if they can explicitly add the intentions behind their writing process. A model called ‘writing intentions’ based on Speech Act theory, which analyzes and represents the author’s intentions is described here. The intentions are coded as a set of metadata and inserted in the document. SABRE (“Système Auteur Basé sur la REutilisation”, an Authoring System Based on Reuse) is a prototype based on the model of writing intentions. It has been implemented and used by authors of educational documents. Authors can express explicitly and edit their pedagogical and communication intentions. The usefulness of such a system is measured in terms of helping authors and readers find documents more efficiently by querying in terms of authorial intentions. Authors can also benefit from such query system to find existing documents for revisions and recycling.

Abstract

Purpose

Research in the area of technology‐enhanced learning (TEL) throughout the last decade has largely focused on sharing and reusing educational resources and data. This effort has led to a fragmented landscape of competing metadata schemas, or interface mechanisms. More recently, semantic technologies were taken into account to improve interoperability. The linked data approach has emerged as the de facto standard for sharing data on the web. To this end, it is obvious that the application of linked data principles offers a large potential to solve interoperability issues in the field of TEL. This paper aims to address this issue.

Design/methodology/approach

In this paper, approaches are surveyed that are aimed towards a vision of linked education, i.e. education which exploits educational web data. It particularly considers the exploitation of the wealth of already existing TEL data on the web by allowing its exposure as linked data and by taking into account automated enrichment and interlinking techniques to provide rich and well‐interlinked data for the educational domain.

Findings

So far web‐scale integration of educational resources is not facilitated, mainly due to the lack of take‐up of shared principles, datasets and schemas. However, linked data principles increasingly are recognized by the TEL community. The paper provides a structured assessment and classification of existing challenges and approaches, serving as potential guideline for researchers and practitioners in the field.

Originality/value

Being one of the first comprehensive surveys on the topic of linked data for education, the paper has the potential to become a widely recognized reference publication in the area.

Abstract

Purpose

The open science movement calls for transparent and retraceable research processes. While infrastructures to support these practices in qualitative research are lacking, the design needs to consider different approaches and workflows. The paper bases on the definition of ontologies as shared conceptualizations of knowledge (Borst, 1999). The authors argue that participatory design is a good way to create these shared conceptualizations by giving domain experts and future users a voice in the design process via interviews, workshops and observations.

Design/methodology/approach

This paper presents a novel approach for creating ontologies in the field of open science using participatory design. As a case study the creation of an ontology for qualitative coding schemas is presented. Coding schemas are an important result of qualitative research, and reuse can yield great potential for open science making qualitative research more transparent, enhance sharing of coding schemas and teaching of qualitative methods. The participatory design process consisted of three parts: a requirement analysis using interviews and an observation, a design phase accompanied by interviews and an evaluation phase based on user tests as well as interviews.

Findings

The research showed several positive outcomes due to participatory design: higher commitment of users, mutual learning, high quality feedback and better quality of the ontology. However, there are two obstacles in this approach: First, contradictive answers by the interviewees, which needs to be balanced; second, this approach takes more time due to interview planning and analysis.

Practical implications

The implication of the paper is in the long run to decentralize the design of open science infrastructures and to involve parties affected on several levels.

Originality/value

In ontology design, several methods exist by using user-centered design or participatory design doing workshops. In this paper, the authors outline the potentials for participatory design using mainly interviews in creating an ontology for open science. The authors focus on close contact to researchers in order to build the ontology upon the expert's knowledge.

Abstract

De/uncolonizing educational visions in the context of insistent and persistent ecological violence is an urgent task, one requiring profound shifts in thinking, being and knowing. Meraki is a Greek word denoting something done or undertaken with all of one's soul. Metanoia is also a Greek word signifying a deep shift in one's way of life resulting from a profound change of heart and worldview. Metis is a figure in Greek mythology known for wisdom and deep thought, but the word has also been used to mean a deeper spiritual awareness or consciousness. This chapter, written by a Greek educator on Turtle Island, explores the imaginaries of ancient Greek ways of knowing with her responsibilities to support decolonizing processes in the place in which she now lives. The author identifies the process of regeneration, of replacing or restoring damaged or missing dimensions of life as a call to which our educational systems must respond. Regeneration is synonymous with rebuilding, restoration, rehabilitation, revival, rebirth, redemption, renewal, recovery, and reconstruction. Her recognition that metanoia (a profound transformative shift) resulting in regeneration done with meraki (soul) and grounded in metis (wisdom and spiritual knowing) forms the basis of her revisioning of schooling and community. In reclaiming hidden structures of Greek wisdom, the author dives below the often incomplete frames of “western” ways of knowing and discourses to redeem deeper ontological frequencies hidden beneath the surface, joining these in constellation with other de/uncolonizing discourses and movements to redeem a “wholeness of being” that must be regenerated for planetary survival. This chapter traces a vision for leadership that reclaims the depth of Spirit and soul that are the basis upon which we can heal the traumas of the legacies of fragmentation, division and violence and remake/regenerate our educational systems.

Abstract

Purpose

To describe a browsing and searching personalization system for digital libraries based on the use of ontologies for describing the relationships between all the elements which take part in a digital library scenario of use.

Design/methodology/approach

Identification of all the desired functionalities and requirements that are necessary to fully integrate the use of a digital library in an e‐learning environment, and the basic elements that are used to build the ontology that describes such scenario.

Findings

The elements that determine the functionalities of the desired personalization system: first, the user's profile, including navigational history and user preferences; and second, the information collected from the navigational behavior of the digital library users.

Research limitations/implications

The ontology is not complete. In fact, the ontology in itself will evolve with the new apparition of desired functionalities and requirements of the personalization system.

Practical implications

Such a personalization system will be very helpful to the users of a digital library to improve their experience of use.

Originality/value

The use of ontologies promotes the integration of new services into existing ones, and the interoperability with other systems through the appropriate semantic web services. New system functionalities and requirements can be added by including the appropriate description into the ontology framework that defines the digital library scenario of use.

Abstract

The situating of pimatisiwin as a framework for spatial justice and self-determination aids educators in strengthening their understandings of Indigenous knowledges to support an authentic inclusion of Indigenous students with disabilities. Through the sharing of Canada’s colonial history, and by critically examining the principles of care within special education, the author exposes its relationship with ableism, normalcy, eugenics, and white privilege to show how Indigenous peoples continue to be marginalized in the twenty-first century. This justice work asks educators to shift their perspectives of inclusion and wellness through the insertion of an Indigenous lens, one to help them see and hear the faces and voices of disabled Aboriginal children and their kinships. The chapter discusses the social model of disability, the psychology of Gentle Teaching, Indigenous ethics, and principles of natural laws through the voices of Nehiyawak and other knowledge keepers, in order to suggest an agenda for educators to come to an understanding of an emancipatory and gentle education. Spatial justice and Indigenous epistemologies merge as synergistic, inclusive, and holistic entities, to support Aboriginal children and youth as both they and those who teach learn to celebrate disabled ontologies. The chapter concludes by presenting how Gentle Teaching and Indigenous ways of knowing should be honored in this quest of creating an equitable, caring, and inclusive society for all disabled Indigenous children and youth.

Abstract

Purpose

The purpose of this paper is to show how personalisation of learning resources and services can be achieved for students with and without disabilities, particularly responding to the needs of those with multiple disabilities in e‐learning systems. The paper aims to introduce ONTODAPS, the Ontology‐Driven Disability‐Aware Personalised E‐Learning System, which has the mechanism for such personalisation.

Design/methodology/approach

This paper reviews current e‐learning systems that provide personalisation for students, including their strengths and weaknesses. The paper presents personalisation and its techniques and then presents ONTODAPS, which personalises learning resources and services to students. In total, three case studies are considered to show how personalisation is achieved using ONTODAPS.

Findings

This paper shows that it is possible to use automated ontology‐based agents intercommunicating to provide an effective personalisation for disabled students. The results reveal that ONTODAPS is flexible enough to provide enough control and freedom to drive their learning. The results also suggest that ONTODAPS has the ability to provide appropriate levels of learner control by allowing them to self‐direct learning through personalising learning resources and then allowing them to choose which resources they wish to access. This thus gives them a sense of ownership and control.

Research limitations/implications

This research reveals that it is possible for e‐learning systems to personalise learning for users with multiple disabilities. Thus, by considering the needs of such users and consulting them in the design and development process, developers of e‐learning systems can produce systems that are both accessible and usable by students with disabilities.

Practical implications

The inclusion of multiple formats of learning resources and personalisation of their presentation to students means students will have increased access to such resources, with the potential of consuming and assimilating the information. This also has the potential of improving understanding and hence and improvement in results.

Social implications

This research shows that ONTODAPS is a medium where disabled students can have equivalent learning experience with their non‐disabled peers. This could potentially increase access to learning for disabled students and possibly help improve their results due to an increase in accessibility of learning resources and usability of the system. This system thus complies with contemporary legislation which requires “reasonable adjustments” or “reasonable accommodations” to be made to meet the needs of disabled people.

Originality/value

Although personalisation has been applied in e‐commerce systems, making them very successful, such personalisation is still a wish for e‐learning systems which struggle to catch up. This research proposes a solution in the e‐learning domain and its novelty is in its application to disabled students, including those with multiple disabilities.
