Processing data received via a network from multiple client devices

A method, comprising:

• receiving, by one or more processors, first tax return data associated with a plurality of first tax return documents;
• parsing, by the one or more processors, the first tax return data to identify a plurality of different types of data included in the first tax return data;
• identifying, by the one or more processors and based on the plurality of different types of data, a plurality of groups,
• each group of the plurality of groups being associated with at least one type of data from the plurality of different types of data;
• associating, by the one or more processors and for each group of the plurality of groups, at least a portion of the first tax return data with the group;
• identifying, by the one or more processors and for a first group of the plurality of groups, a first pattern,
• the first pattern being based on the portion of the first tax return data associated with the first group;
• receiving, by the one or more processors, second tax return data associated with a plurality of second tax return documents from a plurality of client devices,
• assigning, by the one or more processors, the second tax return documents to the plurality of groups based on the plurality of different types of data included in the second tax return data;
• identifying, by the one or more processors and for the first group of the plurality of groups, a second pattern,
• the second pattern being based on a portion of the second tax return data,
• the portion of the second tax return data being associated with second tax return documents assigned to the first group;
• comparing, by the one or more processors, the first pattern to the second pattern;
• determining, by the one or more processors and based on comparing the first pattern to the second pattern, that a subset of the second tax return documents exhibit a change in pattern,
• the subset of the second tax return documents assigned to the first group being associated with a particular group of the plurality of groups;
• and
• updating, by the one or more processors, based on the change in pattern, a monitoring algorithm;
• and
• monitoring, by the one or more processors and using the monitoring algorithm, third tax return documents for a particular type of risk associated with the change in pattern.

A computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors, cause the one or more processors to:
• receive first tax return data associated with a plurality of first tax return documents;
• parse the first tax return data to identify a plurality of different types of data included in the first tax return data;
• identify, based on the plurality of different types of data, a plurality of groups,
• each group of the plurality of groups being associated with at least one type of data from the plurality of different types of data;
• associate, for each group of the plurality of groups, at least a portion of the first tax return data with the group;
• identify, for a first group of the plurality of groups, a first pattern,
• the first pattern being based on the portion of the first tax return data associated with the first group;
• receive second tax return data associated with a plurality of second tax return documents from a plurality of client devices,
• assign the second tax return documents to the plurality of groups based on the plurality of different types of data included in the second tax return data;
• identify, for the first group of the plurality of groups, a second pattern,
• the second pattern being based on a portion of the second tax return data, the portion of the second tax return data being associated with
• second tax return documents assigned to the first group;
• compare the first pattern to the second pattern;
• determine, based on comparing the first pattern to the second pattern, that the second tax return documents exhibit a change in pattern;
• and
• update a monitoring algorithm, based on the change in pattern;
• and
• monitor, using the monitoring algorithm, third tax return documents for a particular type of risk associated with the change in pattern.
