“…c) Organizing concepts: Once the main concepts have been identified, the next common step in ontology development is organizing them in a hierarchical structure. Organizing concepts in a hierarchy helps to show the relationships between different concepts [75]. Here, the upper ontology can guide the structuring of relationships between the domain-specific concepts.…”

“…This step is important as it structures the ontology in a way that reflects the inherent structure of the domain. It also facilitates the understanding and use of ontology by providing a clear and intuitive organization of the concepts [75]. Considerable time and effort are often spent on this step to ensure that the ontology accurately represents the relationships among the concepts in the domain.…”

Ontology, serving as an explicit specification of conceptualization, has found widespread applications across various fields. Business Model Ontology (BMO) stands out as a prominent ontology, especially in the domains of business and entrepreneurship. This study employs the narrative literature review method to delve into the Ontology Development Method (ODM). By identifying commonalities among various ODMs and drawing insights from the BMO, the study proposes a Unified Ontology Approach (UOA) as an alternative ODM. The UOA is derived by combining the common characteristics and key steps of various ODMs, aiming to streamline the ontology development process and enhance its effectiveness. Through an extensive analysis of existing methodologies, this research contributes to the field by offering a consolidated perspective on ODMs. The study findings shed light on the strengths and weaknesses of different approaches, facilitating informed decision-making for ontology developers. Furthermore, the discussion explores the implications of adopting the UOA in practical applications, emphasizing its potential to improve ontology quality, interoperability, and adaptability across diverse domains. In conclusion, this paper advocates for the adoption of the UOA as a comprehensive and flexible framework for ontology development. By synthesizing the strengths of existing ODMs and insights from the BMO, the UOA offers a promising avenue for advancing the field of ontology development and driving progress in various domains and applications.

“…The concept of "roles" has been used in many areas such as linguistics, knowledge representation, relational database, and access control (Biddle, 1979;Fukazawa et al, 2006;Masolo et al, 2004); especially, roles have been widely used in data security domain, under RBAC, e.g., (Sandhu et al, 1996). Sunagawa, Kozaki, Kitamura, and Mizoguchi (2004) proposed an effective ontology development system called Hozo for organizing role-concepts. However, in those approaches, role ontology needs to be manually created.…”

Recent research has attempted to use role-based approaches to recommend mobile services to other members among the same group in a context dependent manner. However, the traditional role mining approaches originated from the domain of security control tend to be rigid and may not be able to capture human behaviors adequately. In particular, during the course of role mining process, these approaches easily result in over-fitting, i.e., too many roles with slightly different service consumption patterns are found. As a result, they fail to reveal the true common preferences within the user community. This paper proposes an online role mining algorithm with a residual term and an error term, that automatically group users according to their interests and habits without losing sight of their individual preferences and random errors. Moreover, to resolve the over-fitting problem, the authors relax the role definition in role mining mechanism by introducing quasi-roles based on the concept of quasi-bicliques. Most importantly, the new concept allows us to propose a monitoring framework to detect and correct over-fitting in online role mining such that recommendations can be made based on the latest and genuine common preferences. To the best of the authors’ knowledge, this is a new area in service recommendation that is yet to be fully explored.

“…En este grupo de herramientas, destacan básicamente dos tipos de propuestas. La primera abarca todas aquellas que se basan en el uso del navegador web, entre las que se encuentran Ontolingua [66], OwlSight [239], WebODE [15], SWOOP [273] y HOZO [247,176]. El resto de las herramientas se ejecutan como cualquier otra aplicación de escritorio, aunque pueden estar dotadas de capacidades para interactuar a través de la web.…”

La Figura 4.1 muestra una vista de la herramienta HOZO [247,176], muy similar en cuanto a su diseño a otras herramientas basadas en web como SWOOP, WebODE, Ontolingua y OwlSight descritas en la sección 2.3.4. HO-ZO se basa en la utilización de listas para la representación de la jerarquía de clases.…”

Los resultados de las evaluaciones han indicado, por un lado, que los procesos, los flujos de trabajo y las tareas definidas, son coherentes con los objetivos definidos. Este resultado se debe en gran parte a que estas tareas se han adaptado a partir de metodologías previamente definidas. Por otro lado, la evaluación de funcionalidad en el caso de estudio, ha permitido detectar algunos aspectos mejorables, así como también ha servido para la validación general de la herramienta y las diversas técnicas de visualización e interacción implementadas en ella.
