... Numerous methodologies for ontology development have been proposed [57][58][59][60][61], yet it is widely accepted that no single approach can be deemed definitely correct or incorrect. Conversely, there are always multiple, viable methods for structuring an ontological representation, with the final model largely influenced by the goals and expectations of its creator [62]. Ontology's domain and scope constitute two decisive factors that guide the adoption of the most appropriate methodology. ...
... It is essential that the concepts included in an ontology correspond closely to relevant objectswhether physical or logical-and the relations applicable within a certain domain. In essence, the purpose for which the ontology is constructed, as well as the desired level of granularity (depth of the hierarchical structure), lead to various modelling decisions [62]. ...
... Given the absence of a standardized and rigid methodology for building ontologies, the steps of ontological development followed in the case of the present study are aligned with a set of general and empirical stages of ontological design and implementation, articulated by Noy and McGuinness [62]. These include: Which specific domain will the ontology cover? ...

The unprecedented pace of urbanization has been exerting significant strain on cities, raising critical concerns across environmental, economic, social, and technological aspects. In response, the 'Smart City' concept has emerged as a novel urban development paradigm, aiming at addressing contemporary urban issues, enhancing cities' competitiveness and prosperity, and fostering active participation through the strategic utilization of state-of-the-art technologies. However, the smart city term suffers from considerable conceptual ambiguity, thereby provoking intense confusion and misunderstanding among interested parties and leading to the implementation of ineffective initiatives. Moreover, the priorities of sustainability, resilience, and inclusiveness have gained prominence in the urban planning discourse, necessitating a more integrated view that aligns urban targets with performance assessment across various domains. In light of these issues , this study endeavors to clarify the above-mentioned conceptual vagueness by developing a holistic, indicator-oriented smart city ontology. The proposed knowledge representation scheme is intended to serve as a Decision Support Tool that will facilitate pol-icymakers to tackle urban challenges and formulate sound policies. Additionally, it is expected to contribute to the fields of spatial and developmental planning by establishing a standardized framework for assessing and monitoring cities' performance, while elucidating the complex interrelationships and trade-offs among diverse urban dimensions.
... Reuse of existing ontologies may be necessary if the developed system will have to interact with other applications that have already come to an ontology or controlled dictionaries [2]. There are libraries of reusable ontologies on the Internet and in the literature, for example, in the Ontolingua ontology library [3], or the DAML ontology library [4]. ...

O presente trabalho aborda a funcionalidade de interpretar imagens como uma tarefa cognitiva em agentes. Para verificar alguns dos limites das abordagens consideradas mais efetivas foram efetuados experimentos com redes convolucionais. A principal contribuição, a partir dos resultados, é a constatação e explicitação de possíveis caminhos para elaborar uma arquitetura cognitiva que, embora utilize aprendizagem profunda para aquisição de entradas, o faça sob um arcabouço cognitivo.
... Ontologies, defined as explicit machine-interpretable specifications of conceptualizations, describe entities within a domain, their attributes, and their interrelationships [13]. They provide a shared vocabulary for humans and machines, facilitating consistent information sharing, systematic analysis, and reuse of domain knowledge [14]. Ontologies are usually formulated in two main languages: RDF and OWL [15]. ...

Healthcare 4.0 addresses modernization and digital transformation challenges, such as home-based care and precision treatments, by leveraging advanced technologies to enhance accessibility and efficiency. Semantic technologies, particularly knowledge graphs (KGs), have proven instrumental in representing interconnected medical data and improving clinical decision-support systems. We previously introduced a semantic framework to assist medical experts during patient interactions. Operating iteratively, the framework prompts medical experts with relevant questions based on patient input, progressing toward accurate diagnoses in time-constrained settings. It comprises two components: (a) a KG representing symptoms, diseases, and their relationships, and (b) algorithms that generate questions and prioritize hypotheses—a ranked list of symptom–disease pairs. An earlier extension enriched the KG with a symptom ontology, incorporating hierarchical structures and inheritance relationships to improve accuracy and question-generation capabilities. This paper further extends the framework by introducing strategies tailored to specific medical domains. Strategies integrate domain-specific knowledge and algorithms, refining decision making while maintaining the iterative nature of expert–patient interactions. We demonstrate this approach using an emergency medicine case study, focusing on life-threatening conditions. The KG is enriched with attributes tailored to emergency contexts and supported by dedicated algorithms. Boolean rules attached to graph edges evaluate to TRUE or FALSE at runtime based on patient-specific data. These enhancements optimize decision making by embedding domain-specific goal-oriented knowledge and inference processes, providing a scalable and adaptable solution for diverse medical contexts.
Chapter
Good Agricultural Practices (GAP), as defined by FAO, are a “collection of principles for on-farm production and post-production processes, resulting in safe and healthy food and non-food agriculture products, while considering economic, social and environmental sustainability.” GAP are about understanding, planning and measurement, record, and management to achieve specific social, environmental, and productive objectives. GAPs goals are: to ensure food safety, to produce in a way that protects the environment and avoids its degradation, to ensure job well-being, and to obtain quality products according to consumer demand. For example, FAO enumerates general categories such as GAP for food safety, to improve market access or ensure water quality. GAP can be achieved by different actions depending on the crop, geography, available tools, and a diversity of variables. A federated catalog of GAPs that could be accessed by different stakeholders using different aspects is desirable. Also, as there are a diversity of GAPs experiences in the world, a catalog about those experiences is a helpful tool to help farmers exchange and adoption of knowledge. This chapter presents a semantic wiki repository that focuses on GAPs related to intensive horticultural activity in aspects that may be subject to improvement. The repository is framed in what is currently considered a collaborative repository. The wiki includes a description, goals, and methodologies of each good practice defined in GAP. Also, the wiki contains links to tutorials, external sites about the agricultural field, and legal documentation.

Ontology development is a multidisciplinary work involving domain experts and knowledge engineers. Bringing together such a team to develop an ontology of quality is not easy. Therefore, ontologies are often created with limited expertise either in the medical domain or in ontology engineering. Unfortunately, the existing methodologies do not provide much guidance on how the different steps of ontology development should be performed, particularly in the case of reduced involvement of domain experts. This challenge is getting more difficult when there is a multitude of medical knowledge sources and ontologies covering parts of the domain, and often each having a different representation of the same concept. This research presents a methodology for creating a medical ontology of quality with limited involvement of the domain experts. The latter are only consulted in the domain definition and evaluation phases. We combine building an ontology from codified knowledge and ontology reuse to enhance reusability and interoperability. The methodology is inspired by METHONTOLOGY for which we make several improvements, especially in the ontology reuse phase. We provide a proof of concept of the proposed methodology with a case study involving the development of the pneumonia diagnosis ontology (PNADO).

Large-scale ontologies are becoming an essential component of many applications including standard search (such as Yahoo and Lycos), e- commerce (such as Amazon and eBay), configuration (such as Dell and PC-Order), and government intelligence (such as DARPA's High Performance Knowledge Base (HPKB) program). The ontologies are becoming so large that it is not uncommon for distributed teams of people with broad ranges of training to be in charge of the ontology development, design, and maintenance. Standard ontologies (such as UNSPSC) are emerging as well which need to be integrated into large application ontologies, sometimes by people who do not have much training in knowledge representation. This process has generated needs for tools that support broad ranges of users in (1) merging of ontological terms from varied sources, (2) diagnosis of coverage and correctness of ontologies, and (3) maintaining ontologies over time. In this paper, we present a new merging and diagnostic ontology environment called Chimaera, which was developed to address these issues in the context of HPKB. We also report on some initial tests of its effectiveness in merging tasks.
