Call for Participation in Machine Learning Schema Community Group

The Machine Learning Schema Community Group has been launched:

This group represents a collaborative, community effort with a mission to develop, maintain, and promote standard schemas for data mining and machine learning algorithms, datasets, and experiments. Our target is a community agreed schema as a basis for ontology development projects, markup languages and data exchange standards; and an extension model for the schema in the area of data mining and machine learning.

The goals of this group are:

To define a simple shared schema of data mining/ machine learning (DM/ML) algorithms, datasets, and experiments that may be used in many different formats: XML, RDF, OWL, spreadsheet tables.

Collect use cases from the academic community and industry

Use this schema as a basis to align existing DM/ML ontologies and develop more specific ontologies with specific purposes/applications

Prevent a proliferation of incompatible DM/ML ontologies

Turn machine learning algorithms and results into linked open data

Promote the use of this schema, including involving stakeholders like ML tool developers
Apply for funding (e.g. EU COST, UK Research Councils, Horizon2020 Coordination and Support Actions) to organize workshops, and for dissemination

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2015-09-28 by Joaquin Vanschoren. The following people supported its creation: Joaquin Vanschoren, Agnieszka Lawrynowicz, Diego Esteves, PanĨe Panov, Diego Moussallem, Carmen Popoviciu. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at

Thank you,
W3C Community Development Team
