User interfaces based on pre-classified data sets

A computer-implemented user interface for displaying reduced data sets based on pre-classification of a larger data set, wherein the computer-implemented user interface is configured to display:

• a description of a pre-classified data set, the pre-classified data set comprising activities of a user that share a common attribute;
• a number of the activities in the pre-classified data set;
• one or more descriptive terms associated with at least a subset of the activities in the pre-classified data set;
• a control that, when selected, allows the user to view information about all of the activities in the pre-classified data set;
• and
• a control that, when selected, allows the user to assign a category to all of the activities in the pre-classified data set.

A system, comprising:

• one or more processors;
• and a non-transitory computer-readable medium comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform an operation for displaying reduced data sets based on pre-classification of a larger data set in a user interface, the operation comprising:
• receiving a plurality of activity records describing a plurality of activities associated with the user;
• grouping the plurality of activities into one or more pre-classified data sets based on the plurality of activity records;
• providing the user with a summary of a pre-classified data set of the one or more pre-classified data sets via a user interface;
• providing the user, via the user interface, with a user interface element that allows the user to categorize all activities in the pre-classified data set together based on the summary;
• receiving input from the user via the user interface, wherein the input assigns a category to all activities in the pre-classified data set together based on the summary.
