20. The computer-implemented method of claim 15 , further comprising: searching the data source to retrieve second search results based on a second list of data elements, the second search results being a same category of data element as the given data element.
15. A computer-implemented method of data validation, the computer-implemented method comprising: creating a list of data elements, the list of data elements including data elements that are similar to a given data element from a set of extracted data elements; searching at least one data source to retrieve search results associated with the list of data elements; correlating the search results with the list of data elements to generate a weighted list of data elements, the weighted list of data elements including an assigned weight for pairs of data elements, each assigned weight indicating a probability of a correct pairing based on information associated with the set of extracted data elements; modifying assigned weights in the weighted list of data elements based on validation rules; wherein modifying assigned weights based on validation rules includes identifying rules associated with the set of extracted data elements that specify expected properties of a given category of data element; and via execution of at least one computer processor, validating the given data element based on modified assigned weights.
