Ontology evolution aims at maintaining an ontology up to date with respect to changes in the domain that it models or novel requirements of information systems that it enables. The recent industrial adoption of Semantic Web techniques, which rely on ontologies, has led to the increased importance of the ontology evolution research. Typical approach...
Article
While research interest on product and service evaluation from unstructured text reviews is increasing, investigating the effectiveness of predictive analytical models in this context is still under-explored. With the advancement in machine learning research, an opportunity exists to bridge this gap using a model-based product and service evaluatio...

The scholarship on Open Strategy and the role of visualization in strategy work are maturing streams of research. Open Strategy scholarship has so far primarily focused on how employees can contribute ideas to strategy making. Also, the lion's share of strategy visualization research has been on the role of visuals in strategy development by top ma...
Article
While the connection between the electronic government development index (EGDI) and sustainable development goals (SDGs) is well established, global efforts to provide appropriate means for achieving SDGs remain insufficient. This study addresses this issue by introducing a hybrid framework using Shannon entropy to derive data-driven weights for ag...
Article
Research on the use of modeling and mapping tools in curriculum management is thriving, often focusing on the perspectives of the faculty alone. However, scholarly works that also incorporate the students curriculum concerns are rare. A recurring theme in students curriculum concerns is the perceived overlap among courses, usually expressed at the...
Article
While education increasingly relies on social media technologies to provide richer learning experiences, the rigid and course-centric design of curricula still imposes a challenge for students to construct meaningful connections between social media and formal learning. Building on the knowledge graphs’ potential to establish semantic links among d...

While actions that products enable their buyers to do are considered to play a significant role in purchase decisions, little attention is given to the integration of such actions in recommender systems. This work proposes the ActionRec framework, to semantically annotate the actions expressed by buyers in product reviews, and to capture the action...
Chapter
From a knowledge representation perspective, higher education programs can be exhibited as a set of concepts exchanged in learning environments to achieve specific learning objectives. Such concepts are often grouped in different blocks such as courses, modules or topics that count towards a degree. Currently, most of program representations are pe...

This paper lays theoretical and software foundations for a World Wide Argument Web (WWAW): a large-scale Web of inter-connected arguments posted by individuals to express their opinions in a structured manner. First, we extend the recently proposed Argument Interchange Format (AIF) to express arguments with a structure based on Walton's theory of a...

Linked Data increases the value of an organisation's data over the web by introducing explicit and machine processable links at the data level. We have adopted this new stream of data representation to produce and expose existing data within The Open University (OU) as Linked Data. We present in this paper our approach for producing the data, based...
Chapter
Ontologies are dynamic entities that evolve over time. There are several challenges associated with the management of ontology dynamics, from the adequate control of ontology changes to the identification and administration of ontology versions. Moreover, ontologies are increasingly becoming part of a network of complex relationships and dependenci...
Conference Paper
Full-text available
Observational studies in the literature have highlighted low levels of user satisfaction in relation to the support for ontology visualization and exploration provided by current ontology engineering tools. These issues are particularly problematic for non-expert users, who rely on effective tool support to abstract from representational details an...
Conference Paper
Full-text available
The aim of this paper is to introduce the current efforts toward the release and exploitation of The Open University's (OU) Linked Open Data (LOD). We introduce the work that has been done within the LUCERO project in order to select, extract and structure subsets of information contained within the OU data sources and migrate and expose this infor...
Conference Paper
Full-text available
While the publication of linked open data has gained momentum in large organisations, the way for users of these organisations to engage with these data is still unclear. Here, we demonstrate a mobile application called wayOU (where are you at the Open University) which relies on the data published by The Open University (under data.open.ac.uk) to...
Conference Paper
Full-text available
Ontology evolution tools often propose new ontological changes in the form of statements. While different methods exist to check the quality of such statements to be added to the ontology (e.g., in terms of consistency and impact), their relevance is usually left to the user to assess. Relevance in this context is a notion of how well the statement...
Article
Full-text available
Thanks to the huge efforts deployed in the community for creating, building and generating semantic information for the Semantic Web, large amounts of machine processable knowledge are now openly available. Watson is an infrastructure component for the Semantic Web, a gateway that provides the necessary functions to support applications in using th...
Conference Paper
Full-text available
Ontology evolution is a painstaking and time-consuming process, especially in information rich and dynamic domains. While ontology evolution refers both to the adaptation of ontologies (e.g., through additions or updates possibly discovered from external data sources) and the management of these changes, no existing tools offer both functionalities...
Conference Paper
Full-text available
Ontology evolution is increasingly gaining momentum in the area of Semantic Web research. Current approaches target the evolution in terms of either content, or change management, without covering both aspects in the same framework. Moreover, they are slowed down as they heavily rely on user input. We tackle the aforementioned issues by proposing E...
Article
Full-text available
Ontology evolution is increasingly getting research momentum in the Seman-tic Web field. This is due to the fact that ontologies, forming the backbone of Semantic Web systems, need to be kept up-to-date for ontology-based systems to remain usable. We highlight two research approaches in the domain of ontology evolution: The first considers the evol...
Article
Full-text available
The tasks of learning and enriching ontologies with new concepts and relations have attracted a lot of attention in the research community, leading to a number of tools facilitating the process of building and updating ontologies. These tools often discover new elements of information to be included in the considered ontology from external data sou...

In this paper, we present an extension to the recently proposed Argument Interchange Format (AIF) to capture Walton's argument schemes.
Article
Full-text available
Large universities tend to spread their services across several departments to serve their substantial student base. It is very common for this to result in developing different systems, which end up in creat-ing many disconnected data silos within the organization. Data isolation is one of the main bottlenecks that prevent unlocking the full poten...
Article
Full-text available
Ontologies form the core of Semantic Web systems, and as such, they need to evolve to meet the changing needs of the system and its users. Most of current ontology evolution systems require user input during their processes. We propose Evolva, an ontology evolution framework, aiming to substantially reduce or even eliminate user input through explo...
Article
Full-text available
One of the current bottlenecks for automating ontology evolution is resolving the right links between newly arising information and the existing knowledge in the ontology. Most of existing approaches mainly rely on the user when it comes to capturing and representing new knowledge. Our ontology evolution framework intends to reduce or even eliminat...
