Construction of marine vocabularies in the Marine Metadata Interoperability Project
Bibliographic record
Abstract
Data producers often overlook existing metadata descriptors and controlled vocabularies for describing their data, opting instead to create custom descriptors and vocabularies. One of the objectives of the Marine Metadata Interoperability (MMI) project is to reduce this vocabulary proliferation. The work is accomplished as community collaborations, which are supported via the content management framework of the MMI Web site. Services, processes, techniques, and advice are all offered via the community Web site supported by the MMI (http://marinemetadata.org). As part of the services, MMI has created and made available marine ontologies based on existing vocabularies. Ontologies are an explicit and formal specification of mental abstractions. Ontologies are being published using the Web Ontology Language (OWL), the ontology expression tool recommended by the World Wide Web Consortium (W3C), and made available using Web services. By providing these services using common terminology, the MMI effort facilitates discovery, sharing, and markup of marine data. The MMI methodology for creating the marine ontologies is composed of: identification, harmonization, alignment and mapping, and publication. First the marine vocabulary is identified. The namespace and the required transformation are then documented. Then the vocabulary is harmonized with the other vocabularies by transforming the vocabulary into a common structure, in this case OWL format. Having all the marine vocabularies harmonized in OWL allows alignment and mapping between the vocabularies. OWL allows the required mapping relationships such as "same As", "narrower Than", and "broader Than". Finally, the ontologies are published via Web services. The first three parts of this methodology, which form the foundation for the development of true semantic interoperability, will be discussed in this paper.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
