Abstract
Disclosed herein are systems, methods and products for interpreting and structuring free text records utilizing extractions of several types including syntactic, role, thematic and domain extractions. Also disclosed herein are systems, methods and products for integrating interpretive extractions with structured data into unified structures that can be analyzed with, among other tools, data mining and data visualization tools.
Claims47
A computer program product located to one or more storage media devices usable to perform integration of mixed format data, said computer program product comprising instructions executable by a computer to perform the functions of:
- accessing a database of structured data, the structured data comprising a set of data tuples;
- accessing a source of unstructured data, the unstructured data including free text relatable to the data tuples of the structured data;
- extracting relational facts from the free text;
- producing a set of construed data reflecting at least one relational fact conveyed in the free text, each construed datum containing at least one relational fact, each construed datum being further relatable to a data tuple of the structured data;
- integrating the produced data with the data tuples of the structured data;
- and
- data mining the integrated data.
