Computer-based identification and validation of data associated with real estate properties

A computing system comprising one or more computing devices programmed with executable program code, the executable program code comprising:

• a first application component configured to process a data submission that comprises multiple elements of information associated with real estate, said data submission received over a network through a data submission interface;
• and
• a second application component that communicates with the first application component, the second application component configured to apply a matching algorithm that matches elements of information to real estate properties represented in a database;
• wherein the first application component is configured to process the data submission by at least:
• using the second application component to validate that the data submission corresponds to a real estate property;
• identifying one or more tax authorities associated with the real estate property at least partly by executing a search of aggregated public assessor data, the aggregated public assessor data obtained from a plurality of public assessor entities and converted to a standard format;
• and
• generating a respective confidence score for each of the one or more identified tax authorities.
