Automatic implementation of attributes for use in entity resolution

A computer system comprising:

• at least one computing device;
• a set of one or more computer-readable storage media;
• and
• program instructions, collectively stored in the set of one or more computer-readable storage media, for causing the at least one computing device to perform computer operations including:
• executing on a computing device of a computing environment a process to automatically generate indexes used in entity resolution, the executing the process including:
• accessing, using the computing device and at least one network of the computing environment, at least one data structure constructed based on data obtained from one or more sources, the at least one data structure stored in storage of the computing environment and including a plurality of columns of data;
• automatically generating, using the computing device and based on the plurality of columns of data, one or more indexing attributes, the automatically generating the one or more indexing attributes comprising:
• generating multiple sub-columns from the plurality of columns of data, wherein a sub-column of the multiple sub-columns is a portion of a selected column of data of the plurality of columns of data, and wherein the generating the sub-column from the selected column of data includes separating the selected column of data into a re type sub-column in which the data of the selected column is of a repeatable type and another type of sub-column including other data of the selected column of data;
• and
• selecting from the plurality of columns of data and the multiple sub-columns at least one indexing column as at least one indexing attribute of the one or more indexing attributes, the at least one indexing attribute used to generate at least one index configured to reduce a number of records compared and storage requirements by avoiding storing duplicate data within the computing environment;
• and
• executing the entity resolution by one or more computing devices of the computing environment using the at least one index generated from the at least one indexing attribute.

• and
• executing the entity resolution by one or more computing devices of the computing environment using the at least one index generated f rom the at least one indexing attribute.
