Abstract: The present disclosure relates to techniques for abstraction of unstructured clinical trial health data. Particularly, aspects are directed to obtaining, by a data transformation system, an unstructured document that includes various types of content for a given event. The data transformation system converts the unstructured document from an original format into a standardized format. The data transformation system processes the unstructured document in the standardized format to identify template-mapped content data and processes the template-mapped content data to identify high-interest content data. The data transformation system generates a dictionary data structure comprising key-value pairs for each of the template-mapped content data and the high-interest content data. The data transformation system generates a structured document based on the dictionary data structure for each of the template-mapped content data and the high-interest content data.
