Abstract
Methods, systems and computer program products for implementing a mere-parser are disclosed. Text data is processed to generate one or more parse items. A boundary based attribute associated with one of the parse items is identified, and the identified mere attribute is associated with one or more of the remaining parse items that is not blocked from associated with the boundary based attribute.
Claims20
A computer-implemented mere-parser system comprising:
- a parse item bounding system configured to:
- normalize source input text to a standardized plain text format;
- identify and normalize special words or phrases within the normalized source input text, wherein the special words or phrases include temporal and spatial descriptions and/or medication dosages;
- identify boundary markers in the normalized special words or phrases;
- generate one or more parse items based on the identified boundary markers;
- and
- identify boundary-based attributes that propagate;
- a linear propagation system, communicatively coupled with the parse item bounding system, configured to iteratively determine:
- whether each of the one or more parse items includes a propagating attribute;
- and
- a direction of the propagating attribute;
- and
- a tree building system, communicatively coupled with the linear propagation system, configured to generate a merged parse item from at least two of the parse items.
