Document container with candidate documents

A method comprising:

• determining an attribute for an input document for execution by a signer;
• generating a similarity score for a plurality of candidate documents using a machine learning model, wherein using the machine learning model comprises providing the attribute as an input to the machine learning model;
• determining a subset of the candidate documents based on the similarity scores generated for each of the plurality of candidate documents;
• determining that a field classification for a first field of the input document corresponds to a field classification for a second field of a related document of the subset of the candidate documents;
• based on the determination that the field classification for the first field corresponds to the field classification for the second field, generating a common field that includes the field classification of the first field;
• and
• setting one or more of a first field value of the first field or a second field value of the second field to a common field value of the common field.

Computer readable storage media encoded with instructions that, when executed, cause one or more processors of a computing device to:

• determine an attribute for an input document for execution by a signer;
• generate a similarity score for each of a plurality of candidate documents using a machine learning model, wherein using the machine learning model comprises providing the attribute as an input to the machine learning model;
• determine a subset of the candidate documents based on the similarity scores generated for each of the plurality of candidate documents;
• based on a determination that a field classification for a first field of the input document corresponds to a field classification for a second field of a related document of the subset of the candidate documents, generate a common field that includes the field classification of the first field;
• and
• set one or more of a first field value of the first field or a second field value of the second field to a common field value of the common field.
