Abstract

In an illustrative embodiment, an automated system determines similarities between properties at a location using customized features sets. The system can generate feature sets for properties from property attribute data received from external and internal sources. The system can transform one or more elements of attribute data of combined internal and external data into customized property attributes that enhance property attribute comparisons. The combined attribute data can be applied to a machine learning algorithm that identifies a portion of the combined attribute data for using in property similarity calculations. Using the identified features, the system can calculate similarity scores identifying an amount of similarity between properties at the location and a property identified in a comparable property query, which can be output to an external device.
