+# SymbiOnt: Augmenting and merging ontologies using ontology mappings and knowledge graph embeddings
+
+No matter how hard we try to reconcile our ontologies -- for example, as part of efforts such as the [OBO Foundry](https://obofoundry.org/) --
+there will always be some level of overlap between them, i.e. the same terms existing in multiple ontologies.
+Data is regularly linked to concepts from different (sometimes internal, non-public) ontologies, and this data needs to be integrated – 
+which means that the different ontologies need to be carefully aligned.
+Furthermore, we want to be able to enrich our own ontologies with information (such as synonyms) from and links to other public sources.
+
+Ontology and Knowledge Graph Matching seeks to find ways to link terms between ontologies,
+employing techniques such as string-based matching, graph-based matching or more advanced techniques from Natural Language Processing (NLP).
+Recently, Machine Learning (ML) algorithms and Knowledge Graph embeddings have been used to greatly enhance traditional mapping techniques, and we expect a lot more to come here.
+Ontology Merging is concerned with combining two ontologies in a way that the resulting whole is consistent, yet richly axiomatised, and uses approaches from formal logic to Bayesian.
+Ontology Engineering is the “art” of evolving an ontology in a sustainable way,
+for example using design patterns, logical reasoning and more classical visualisation approaches focused on manual curation and automated quality control.
+
+With SymbiOnt, we bring together techniques from all of the above to provide a fully executable workflow for ontology merging and augmentation.
+The goal is to combine tools and techniques in a Docker-based workflow that enables the end-to-end merging and augmentation of ontologies.
+For example, we want to be able to combine the many existing disease ontologies and terminologies into a rich coherent framework
+and keep them synchronised with minimal human curation effort.
+
+The SymbiOnt project is led by [Nico Matentzoglu](https://github.com/matentzn).
