Base Claim:
1. A computer-implemented method of validating real property data, the computer-implemented method comprising: extracting data elements from fields of a document that includes real estate information, each data element comprising a unit of data; analyzing content of the document to create business rules that represent relationships among content of the document, data elements from fields of the document, and real estate information; identifying a first data element and a second data element from the extracted data elements; generating multiple data elements that are variations of the first data element; generating multiple data elements that are variations of the second data element; using the multiple data elements that are variations of the first data element to search at least one database to retrieve a first set of search results, the first set of search results being a same type of data element as the second data element, the at least one database including real estate information; using the multiple data elements that are variations of the second data element to search at least one database to retrieve a second set of search results, the second set of search results being a same type of data element as the first data element, the at least one database including real estate information; correlating the first set of search results to the second set of search results to identify a measure of similarity between pairs of generated data elements and retrieved search results; assigning weights to each pair of generated data element and retrieved search result based on the measure of similarity; modifying assigned weights based on analysis using the created business rules; wherein modifying assigned weights based on business rules includes identifying rules associated with the set of extracted data elements that specify expected properties of a given category of data element; and in response to identifying an absence of an anomaly with the first data element based on the modified assigned weights, validating the first data element; and in response to identifying an anomaly with the first data element based on the modified assigned weights, automatically correcting the first data element.

Claim 2:
2. The computer-implemented method of claim 1 , wherein generating multiple data elements that are variations of the first data element includes generating at least a portion of the multiple data elements based on identified patterns of errors.
