“A large amount of data is generated every day by various systems and applications. In many cases, this data comes into a tabular format, which lacks semantic representation and poses new challenges in data modeling. It is necessary to elevate the data into a richer representation, such as a knowledge graph adhering to an ontology. This will assist in the development of data modeling and integration. We propose an unsupervised approach, Tab2Onto, for learning ontologies from tabular data using knowledge graph embeddings, clustering, and a human in the loop. We conduct a set of experiments to investigate our approach on a benchmarking dataset from a medical domain to learn ontology of diseases.”
