An Ontology for Integrating Diverse Research Domains in the National Research Data Infrastructure (NFDI)

Q: How can the representation and reasoning of complex roles, processes, and relationships in NFDIcore be further improved to enhance its usability and integration across diverse research communities?

To enhance the representation and reasoning of complex roles, processes, and relationships in NFDIcore, several strategies can be employed. First, the ontology can incorporate more detailed role hierarchies and relationships that reflect the specific contexts in which these roles are enacted. By defining sub-roles and contextual properties, NFDIcore can provide a richer semantic framework that captures the nuances of interactions among agents, resources, and processes. Second, the integration of advanced reasoning capabilities, such as those provided by Description Logics (DL) or other semantic web technologies, can facilitate more sophisticated queries and inferences. This would allow users to derive implicit knowledge from explicit data, enhancing the ontology's usability for complex research questions. Third, user-centered design principles should be continuously applied, involving domain experts in the iterative development process. Gathering feedback through workshops and user stories can help identify specific needs and expectations, ensuring that the ontology remains relevant and user-friendly. Lastly, the implementation of additional SWRL (Semantic Web Rule Language) rules can simplify complex relationships into more accessible representations. By providing shortcuts for common queries, NFDIcore can cater to users with varying levels of expertise, thus improving overall usability and integration across diverse research communities.

Q: What are the potential challenges and limitations in aligning the detailed, BFO-compliant model of NFDIcore with existing ontologies and standards used in different research disciplines?

Aligning the detailed, BFO-compliant model of NFDIcore with existing ontologies and standards presents several challenges and limitations. One significant challenge is the inherent complexity and variability of domain-specific ontologies. Different research disciplines often have unique terminologies, concepts, and relationships that may not directly map to the BFO framework. This can lead to ambiguities and inconsistencies when attempting to integrate diverse ontologies. Another limitation is the potential for semantic mismatches between NFDIcore and existing standards. For instance, while BFO provides a foundational ontology, other ontologies may prioritize different aspects of data representation, leading to conflicts in how entities and relationships are defined. This can complicate interoperability and hinder effective data exchange across disciplines. Additionally, the rigorous structure of BFO may not accommodate the flexibility required by some research domains, which may prefer more lightweight or less formalized representations. This tension between the need for detailed, formal ontologies and the desire for user-friendly, flexible models can create barriers to adoption and integration. Finally, the ongoing evolution of both NFDIcore and external ontologies necessitates continuous alignment efforts, which can be resource-intensive and require sustained collaboration among diverse stakeholders. Ensuring that NFDIcore remains adaptable while maintaining its foundational integrity is a critical challenge that must be addressed.

Q: How can the modular design of NFDIcore be leveraged to facilitate the seamless integration of domain-specific knowledge and requirements, while maintaining the overall coherence and interoperability of the ontology?

The modular design of NFDIcore can be effectively leveraged to facilitate the seamless integration of domain-specific knowledge and requirements by adopting a structured approach to ontology extension. Each research consortium can develop its own module tailored to its specific needs, while still adhering to the overarching principles and structure of NFDIcore. This allows for the representation of unique concepts and relationships pertinent to each domain without compromising the integrity of the core ontology. To maintain overall coherence and interoperability, clear guidelines and best practices for module development should be established. These guidelines can include standards for naming conventions, relationship definitions, and integration protocols, ensuring that all modules align with the foundational BFO principles and can interact seamlessly with one another. Furthermore, the use of shared vocabularies and mappings to established ontologies, such as schema.org and DCAT, can enhance interoperability across modules. By ensuring that domain-specific modules are compatible with widely accepted standards, NFDIcore can facilitate data exchange and collaboration across different research communities. Regular communication and collaboration among the various consortia are essential for identifying common challenges and opportunities for integration. By fostering a community of practice around NFDIcore, stakeholders can share insights, address potential conflicts, and collectively enhance the ontology's usability and effectiveness. In summary, the modular design of NFDIcore not only allows for the incorporation of diverse domain-specific knowledge but also supports a coherent and interoperable framework that can adapt to the evolving needs of the research landscape.

Grunnleggende konsepter

NFDIcore 2.0 is a BFO-compliant ontology that enables interoperability across heterogeneous research domains within the National Research Data Infrastructure (NFDI) in Germany, facilitating cross-domain research and knowledge discovery.

Sammendrag

The paper presents NFDIcore 2.0, an ontology designed to represent the diverse research communities of the National Research Data Infrastructure (NFDI) in Germany. NFDIcore ensures interoperability across various research disciplines by adopting a modular approach, where domain-specific requirements are addressed through ontology extensions.

The development of NFDIcore 2.0 was guided by a user-centered design approach, incorporating feedback and requirements from multiple NFDI consortia, including NFDI4Culture, NFDI-MatWerk, NFDI4DataScience, and NFDI4Memory. The ontology leverages the Basic Formal Ontology (BFO) as its top-level ontology, ensuring a universal and foundational representation of core concepts. It also integrates established standards and external ontologies, such as schema.org and DCAT, to facilitate smooth data integration and exchange across domains.

NFDIcore 2.0 introduces several key features:

Representation of independent continuants, including agents, collections, and places, and their context-specific roles.
Modeling of research artifacts, such as datasets, data portals, and services, as information content entities with detailed relationships.
Incorporation of planned processes, events, and complex relationships to capture the multifaceted nature of research activities.
Provision of SWRL rule-based shortcuts to enable both detailed and simplified representations, enhancing usability and integration.
Modular design that allows for domain-specific extensions, addressing the unique requirements of individual research communities.

The evaluation of NFDIcore 2.0 across multiple NFDI consortia has demonstrated its effectiveness in representing and integrating heterogeneous research domains, while also highlighting areas for future development and enhancement.

"Knowledge Graph supported research data infrastructures are currently being developed in domain specific, national, and international efforts to facilitate advanced data discovery, scientific collaboration, and innovation."
"The NFDI consortia share similar overarching goals and concepts, including their structure, governance, persons, institutions, areas of expertise, data repositories, devices, services, and more."
"Ensuring the interoperability of the research (meta) data among these NFDI consortia has significant benefits and allows for knowledge discovery across research domains."

Sitater

"To achieve a high level of interoperability, and hence to be able to answer these questions, a data model is needed that represents the overarching concepts of the domains on the one hand and meets the specific requirements of the individual communities on the other."
"The originality of the presented approach lies in its combination of compliance with the well-established BFO as an upper ontology, the introduction of short-cuts by means of SWRL rules, and a modular and extensible design tailored to various research domains."
