About the Project

According to Mind [1], 1 in 4 people will experience a mental health problem of some kind each year and 1 in 6 will report experiencing a common mental health problem (like anxiety and depression) in any given week in England. Identification, communication and integration of patients’ data can help clinicians and other medical professionals support patients and ultimately provide effective service and reduce the cost in the health care system.

A great deal of biomedical data are being created and accumulated, in labs and clinics, but also, by patients themselves on Social Media. Recently, machine learning algorithms are being used widely to detect, extract, classify and encode knowledge from big biomedical data [2].  Ontologies as conceptualisation of domain knowledge are also being used extensively in the biomedical domain to integrate and effectively utilise this data (there are more than 800 ontologies on BioPortal [3]). 

Combining ontologies and machine learning in this domain is likely to bring many benefits [4], namely: using the reasoning power of the ontology models to encapsulate and optimise knowledge representation in the domain, using ontologies for semantic similarity computation and data integration, as well as ontology embeddings to improve the learning models.

This project will build on the expertise gathered in previous, ongoing project carried out in the School on the subject of ontology-driven learning for a specific mental disorder and will extend the work into building ontologies and learning models for general mental disorders.

The project’s aim is to provide tools for aligning and integrating already established standard ontologies, such as SNOMED-CT and the Mental Disease Ontology [5]. Ontology enrichment methods will be developed using formal and informal resources on the Web. The aim is encoding language used by patients, in addition to that used by medical experts. The developed ontologies will then be used to demonstrate use cases on ontology-guided machine learning, e.g., automatic annotation of language used on Social medical forums.  The team is working closely with Cardiff School of Medicine who provide valuable domain expertise for evaluating the developed methods and resources.
