Determining activity importance to a user

A system comprising:

• a non-transitory computer-readable medium comprising a group of activities;
• and
• program instructions stored on the non-transitory computer-readable medium and executable by an activity assistant processing system to:
• access the group of activities, wherein the group of activities includes one or more activities added by a user to the group of activities and one or more activities suggested for the user;
• for each particular activity in the group of activities, determine a score for the particular activity, wherein the score is based on at least one signal associated with a plurality of parameters comprising one or more user-specific parameters of the user and one or more global parameters, the one or more user-specific parameters comprising a mood of the user as indicated by the user, the one or more global parameters comprising a mood associated with the particular activity, and the plurality of signals comprising a signal based on a similarity between the mood of tire user and the mood associated with the particular activity;
• identify a subset of activities within the group of activities, wherein the subset comprises at least one activity with a determined score that is greater than or equal to a decision threshold for the at least one activity;
• rank at least a portion of the subset of activities based on the relative scores of the activities in the subset;
• and
• provide for display the ranked portion of tile subset of activities for the user,
• wherein a ratio of a number of the suggested activities in tile ranked portion of activities to be provided for display to a number of the user-added activities in the ranked portion of activities to be provided for display is based on the mood of the user.

An article of manufacture including a tangible computer-readable media having computer-readable instructions encoded thereon, which when executed by a machine, cause the machine to perform operations comprising:

• creating a group of activities, wherein tile group of activities includes one or more activities added by a user to the group of activities and one or more activities suggested for the user;
• accessing the group of activities stored on tangible, non-transitory computer readable media;
• for each particular activity in the group of activities, determining a score for the particular activity, wherein the score is based on a plurality of signals associated with user-specific parameters and global parameters to determine quantitative importance of the particular activity, the one or more user-specific parameters comprising a mood of the user as indicated by the user, the one or more global parameters comprising a mood associated with the particular activity, and the plurality of signals comprising a signal based on a similarity between the mood of the user and the mood associated with the particular activity;
• identifying a subset of activities within the group of activities, wherein the subset comprises at least one activity with a determined score that is greater than or equal to a decision threshold for the at least one activity;
• ranking at least a portion of the subset of activities based on the quantitative importance of the activity;
• and
• generating a display of the ranked portion of the subset of activities and the quantitative importance of the particular activity for the user,
• wherein a ratio of a number of the suggested activities in the ranked portion of activities to be generated on the display to a number of the user-added activities in the ranked portion of activities to be generated on the display is based on the mood of the user.
