* ''' | * '''Chris Mungall''' and '''Justin Reese''' ''COVID-19 Knowledge Graphs'' | ||
* | * Chris Mungall is Department Head of Biosystems Data Science at Lawrence Berkeley National Laboratory. His research interests center around the capture, computational integration, and dissemination of biological research data, and the development of methods for using this data to elucidate biological mechanisms underpinning the health of humans and of the planet. He is particularly interested in developing and applying knowledge-based AI methods, particularly Knowledge Graphs (KGs) as an approach for integrating and reasoning over multiple types of data. Dr. Mungall and his team have led the creation of key biological ontologies for the integration of resources covering gene function, anatomy, phenotypes and the environment. He is a PI on major projects such as the Gene Ontology (GO) Consortium, the Monarch Initiative, the NCATS Biomedical Data Translator, and the National Microbiome Data Collaborative project. In collaboration with Stanford University, Dr. Mungall is leading the creation of a new BioPortal Knowledge Graph. | ||
* Justin Reese is a Computer Research Scientist at LBNL. His research focuses on using computational methods to extract actionable knowledge from biomedical and biological data, and in particular, developing performant graph machine learning algorithms to extract knowledge from biomedical knowledge graphs. Dr. Reese, along with Dr. Mungall, led the KG-Covid-19 project, which included methods for performing inference over the KG. The knowledge graphs generated by the project have been leveraged by the National Virtual Biotechnology Laboratory (NVBL) Therapeutics project and the National COVID Cohort Collaborative (N3C) for accessing integrated COVID-related data. Starting in 2022, Dr. Reese will lead the LBNL team in a new project to develop machine learning tools and best practices to improve the response to COVID-19, leveraging a large range of patient-level COVID-19 data in the National COVID Cohort Collaborative (N3C) Enclave. | |||

[12: | [12:13] RaviSharma: hello and welcome | ||

[12: | [12:24] Chris Mungall: The semantic web community are moving in this direction with 1G | ||
[12: | [12:25] Chris Mungall: Semantic Similarity: let me pull up some references.. | ||
[12: | [12:26] Chris Mungall: Ravi: that kind of contextualized knowledge may go beyond what we have in the KG at the moment. We may have tissue-independent representations of the underlying biological pathways but are lacking tissue-specific models | ||

[12:39] Chris Mungall: We are not using semantic similarity explicitly with the KG embedding approach, but there are similarities -- we can measure similarity between the embedded vectors for any two concepts or individuals using standard measures like cosine similarity.

Ontology Summit 2022 COVID-19 KGs
Dealing with Disasters
The COVID-19 pandemic as well as other pandemics and disasters have prompted an impressive, worldwide response by governments, industry, and the academic community. Ontologies can play a significant role in search, data description, interoperability and harmonization of the increasingly large data sources that are relevant to disasters such as the COVID-19 pandemic. The Ontology Summit 2022 examined the overall landscape of disasters and related ontologies. A framework consisting of a set of dimensions was developed to characterize this landscape. The framework was applied to health-related disasters, environmental disasters, as well as aerospace and cyberspace disasters. It was found that there are many cross-domain linkages between different kinds of disasters and that ontologies developed for one kind of disaster can be repurposed for other kinds. A representative sample of projects that have been developing and using ontologies for disaster monitoring and response management is presented to illustrate best practices and lessons learned. The Communiqué ends by presenting the findings and recommendations of the summit.
