Overview

Knowledge Graphs provide healthcare and life-sciences companies with a connected and meaningful view into their data. However currently, this involves a complex, multi-step process of data collection, mapping, inference, NLP and loading into a Graph Database before a knowledge graph can truly be made operational.

This is the reason we are introducing a unique open source library: Graphster that makes the process of building, analyzing and querying knowledge graphs simple and seamless all using Apache Spark. Watch the talk we gave about Graphster in the NLP summit :

We talk about how to ingest clinical trials data, infer relationships from text, reveal the semantic content by fusing it with the MeSH ontology and then analyze it at scale using SPARQL queries all using the power of Spark NLP and Graphster.

The talk also focused on annotating medical notes for patients experiencing a particular symptom. The rule-based algorithm extracts knowledge in the form of rules from the classification model, which are easy to comprehend and very expressive

This algorithm annotates each note as having or not having a particular symptom, thus making it easier for annotators with non-medical background to annotate medical records.
