Abstract

Text input data may be aggregated and mapped to create composite text input data for electronic records. A semantic event may be automatically detected, triggered by a semantic rule and associated semantic tag. The detected semantic event may be flagged, and a text mining result database may be updated by adding an entry to the database. An indication associated with the event may be transmitted, and a back-end application computer server may establish a hierarchy for multiple elements of the electronic records. The computer server may determine a weight variable and response variable for each element in the hierarchy and apply a hierarchical credibility weighting methodology to the elements from level 1, representing the least granular level in the hierarchy, to level n, representing the most granular level in the hierarchy, calculated recursively from level n, to determine a final estimated credibility for the electronic records.

First claim

What is claimed:

1. A system for determining a credibility weighting associated with electronic records, comprising:
a text mining platform, including:
a text mining communication device to receive text input data associated with the electronic records;
a text mining processor coupled to the text mining communication device; and
a text mining storage device in communication with said text mining processor and storing instructions adapted to be executed by said text mining processor to:
(i) aggregate and map the received text input data to create composite text input data,
(ii) automatically detect a semantic event in the composite text input data triggered by a semantic rule,
(iii) update a text mining result database, responsive to the detection, by adding an entry to the database identifying the detected semantic event, and
(iv) transmit an indication associated with the semantic event based on data in the text mining result database; and

a back-end application computer server coupled to the text mining platform, including:
a back-end communication device to receive the indication for the electronic record transmitted by the text mining platform;
a back-end processor coupled to the back-end communication device; and
a back-end storage device in communication with said back-end processor and storing instructions adapted to be executed by said back-end processor to:
(i) establish a hierarchy for multiple elements of the electronic records,
(ii) determine a weight variable and response variable for each element in the established hierarchy,
(iii) apply a hierarchical credibility weighting methodology to the elements of the electronic records from level 1, representing the least granular level in the hierarchy, to level n, representing the most granular level in the hierarchy, calculated recursively from level n, to determine a final estimated credibility for the electronic records based on the weight variable and response variable, wherein ω i represents a weight for level i, X i represents an observed experience for level i, K represents a credibility factor, and the credibility for level i is calculated as:

Z
i

=

ω
i

ω

+
K

,

 and
(iv) output an indication of the final estimated credibility for the electronic records.

2. The system of claim 1 , wherein if there is not enough data associated with a granular level in the hierarchy to be credible, then the level of granularity is decreased until enough data is obtained for the level to be credible.

3. The system of claim 1 , wherein the semantic event is associated with at least one of: (i) a word, (ii) a phrase, (iii) a shorthand term, (iv) a course of action, and (v) an enterprise name.

4. The system of claim 1 , wherein the triggering semantic rule is associated with at least one of: (i) a noun, (ii) a verb, (iii) a definition, (iv) a semantic tree, (v) a named entity recognition rule, (vi) a root, (vii) a noun phrase, (viii) a prepositional phrase, and (ix) a verb phrase.

5. The system of claim 4 , wherein the triggering semantic rule was defined by an administrator using a graphical user interface.

6. The system of claim 1 , wherein the observed experience for level i, excluding lower levels in the hierarchy, is calculated as:

X

.

7. The system of claim 6 , wherein the credibility for level i, excluding lower levels in the hierarchy, is calculated as:
Z′ i =Z i −Z i+1 .

8. The system of claim 7 , wherein the credibility weighted estimate for level n is calculated as:
{circumflex over (X)} n =Σ i=1 n X′ i *Z′ i .

9. The system of claim 1 , wherein the electronic records are associated with insurance claims, the weight variable comprises a text flag total claim count, and the response variable comprises a text flag ratio.

10. The system of claim 9 , wherein the insurance claims comprise workers' compensation insurance claims.

11. The system of claim 10 , wherein the final estimated credibility is associated with at least one of claim litigiousness and adverse claim severity summarized at a geographic level.

12. The system of claim 11 , wherein the established hierarchy includes at least four of: (i) effective year, (ii) a risk state, (iii) a Combined Statistical Area (“CSA”), (iv) a Core Based Statistical Area (“CBSA”), (v) a Federal Information Processing Standard (“FIPS”) code, (vi) a county, and (vii) a five-digital ZIP code.

13. The system of claim 1 , wherein higher levels of the established hierarchy exclude the experience and credibility from the lower levels, credibility weighted values of the full hierarchy are set relative to the credibility weighted values of the hierarchy to normalize the data, and the final estimated credibility is used in connection with at least one of: (i) an insurance pricing process, and (ii) a risk score model.

14. The system of claim 1 , wherein the text input data is associated with at least one of: (i) an insurance claim file, (ii) an insurance claim note, (iii) a medical report, (iv) a police report, (v) social network data, (vi) big data information, (vii) a loss description, (viii) an injury description, (ix) a first notice of loss statement, (x) telephone call transcript, (xi) optical character recognition data, (xii) third-party data, and (xiii) a governmental agency.

15. A computer-implemented method for determining a credibility weighting associated with electronic records, comprising:
aggregating and mapping, by a text mining platform processor, received text input data to create composite text input data for the electronic re
