Executive summary

Data overview:

The EU Pollinator Hub (EUPH) provides a controlled vocabulary (EUPH-CV) for datastandardisation. A subset of the EUPH-CV has been designed as an ontology, the Pollinator Ontology, in which terms are arranged in a hierarchical structure, enriched with definitions, formal relationships between terms, and other properties (e.g., relations to metadata standard elements, comments, images, and version information).

Data value:

The classes im the controlled vocabulary and the relationships between them serve as a backbone (1) for the definition of the metadata standard elements (EUPH-MS), (2) for the standardisation of data stored on the EUPH in the form of literals, resource identifiers or resource description frameworks (RDF), and (3) for the alignment of terminologies from different vocabularies. The Pollinator Ontology is a crucial technology in knowledge management, big data processing, and machine learning. The use of terms from ontologies to annotate research data greatly improves automated data interpretation and interoperability and, hence, compliance with FAIR principles.

Data description:

The dataset contains 4 files, which are required to analyse the ontoplogy metrics. File terms.csv (442 733 bytes) contains the basic information on the classes. File terms_to_terms.csv (117 650 bytes) contains the relationships between classes. File translations.csv (2 285 199 bytes) contains the translations of the classes to human languages. The file language.csv (1 441 bytes) contains the name of the human languages.

Data application:

The data should be used to validate the method used in the manuscript "The EU Pollinator Hub Controlled Vocabulary: An Ontology for Pollinators" submitted for publication in December 2025.

Introduction

The Pollinator Ontology of the EU Pollinator Hub Controlled Vocabulary (EUPH-CV) is an ontology for information and data about pollinators and their interaction with the abiotic and biotic environment, particularly humans. It contains a series of concepts, referred to as classes, their properties and the relationships between them. A first version of the ontology has been deployed as part of a web-based open-source software application, the EU Pollinator Hub, a tool that has been developed, among others, to promote (1) the standardisation and internationalisation of data related to pollinators, (2) the community-driven development of the ontology and (3) the integration of existing vocabularies in the future.

Material and methods

Data acquisition

Data was collected with the vocabulary management user interface of the EU Pollinator Hub, which has been developed to create and maintene the Controlled Vocabulary and which is regulated by a set of SOP (Standard Operating Procedures) and Work Instructions (WI).

Abstract

The Pollinator Ontology, a subset of the EU Pollinator Hub Controlled Vocabulary (EUPH-CV), is an ontology for information and data about pollinators and their interaction with the abiotic and biotic environment, particularly humans. It contains a series of concepts, referred to as classes, their properties and the relationships between them. A first version of the ontology has been deployed as part of the EU Pollinator Hub, a tool that has been developed, among others, to promote (1) the standardisation and internationalisation of data related to pollinators, (2) the community-driven development of the ontology and (3) the integration of existing vocabularies in the future.
