Visualizing large-scale data in health care is becoming one of the complicated challenges in the big data community. Challenges arise from the heterogeneous and unstructured nature of data as well as complex relationships between different entities. At Zephyr Health, we address these problems by integrating disparate, heterogeneous data sources for deriving analytics and meaningful insights from the data. We have designed ontology that contains vocabulary and taxonomy specifically for pharm-world focusing on integrating disparate heterogeneous datasets. The Zephyr Analytics Platform provides a strong foundation based on adaptive entity-attribute model built over MongoDB and Neo4j.

In this presentation the audience will learn about:

  • Composing entity-attribute-value composition model in MongoDB and Neo4j
  • A flexible and efficient way to organize the data for big set operations
  • Combining relevant information for each entity and storing the 360-view of the profiles in MongoDB
  • Connecting heterogeneous data using machine learning algorithms and fuzzy logic
