Claim 0:
1. A computer implemented method comprising:
receiving at a computer processor a set of structured claims data corresponding to a plurality of property loss insurance claims;
associating, using the computer processor, the property loss insurance claims with categories based on the set of structured claims data;
filtering, using the computer processor, the associated property loss insurance claims based on the association of the property loss insurance claims with categories;
removing, using the computer processor, from the filtered property loss insurance claims, property loss insurance claims associated with a specific policyholder to create a set of qualifying insurance claims;
receiving at the computer processor a set of unstructured textual claims data corresponding to the plurality of property loss insurance claims;
removing, using the computer processor, at least certain textual data from the set of unstructured textual claims data to generate a filtered set of unstructured textual claims data, the filtered set of unstructured textual claims data including an initial vocabulary set;
adding, using the computer processor, pre-identified text to the filtered set of unstructured textual claims data to generate a final set of unstructured textual claims data, the pre-identified text including one or more bigrams;
associating the final set of unstructured textual claims data with the set of qualifying insurance claims, wherein the final set of unstructured textual claims data comprises data describing claims associated with subrogation and claims not associated with subrogation, wherein a number of the claims associated with subrogation is the same as a number of claims not associated with subrogation;
in response to the set of qualifying insurance claims being within a predetermined time period, assigning, using the computer processor, a probability score to the set of qualifying insurance claims and updating the probability score on a periodic basis, the probability score being a likelihood that a qualifying insurance claim from the set of qualifying insurance claims is subrogated;
aggregating, using the computer processor, the set of qualifying insurance claims and their respective assigned probability scores based on one or more property loss categories associated with the property loss insurance claims;
arranging, using the computer processor, the aggregated set of qualifying claims within each category, based on their respective assigned probability scores;
transmitting, using the computer processor, the arranged set of qualifying insurance claims to a database for review;
dividing, using the computer processor, the final set of unstructured textual data into a plurality of subsets of textual data based on the one or more property loss categories;
training, using the computer processor, a model using each of the plurality of subsets of textual data to form a plurality of trained models, each corresponding to one of the one or more property loss categories;
selecting, using the computer processor, one of the plurality of trained models based on the one or more property loss categories;
processing data describing a property insurance loss claim using the selected model; and
determining whether to analyze the property insurance claim for subrogation based on the processing.
