1. A system for ontology driven data mining, comprising:
- an informatics system coupled to a plurality of data sources, the informatics system comprising a processor and a non-transitory computer readable medium comprising instructions for;
receiving a clinical text as input from one or more of the plurality of data sources;
creating a graph representation of the input, wherein creating the graph representation of the input comprises parsing the input to create a parse graph by creating a set of evidence spaces comprising a set of related concepts within a distance of one another in the input;
obtaining a graph representation of a semantic ontology, wherein the semantic ontology comprises a set of concepts and a set of relationships;
mapping the graph representation of the input to the graph representation of the semantic ontology to create a unified graph comprising the graph representation of the input and the graph of the semantic ontology;
constructing a query based on at least one of the set of concepts or at least one of the set of relationships of the semantic ontology; and
searching the unified graph based on the query to obtain data of the input associated with the at least one concept or the at least one relationship.

Abstract
Embodiments of methods and systems for informatics systems are disclosed. Such informatics systems may utilize a unifying format to represent text to facilitate linking between data from the text and one or more ontologies, and the commensurate ability to mine such data.
