The present disclosure relates to dynamically generating and updating confidence scores of values of fields based on data points. A system having access to a plurality of data points corresponding to electronic activities and record objects can identify a node profile of the plurality of node profiles including a plurality of fields, determine, for at least one data point of the one or more data points included in a respective value data structure of a value of a field of the plurality of fields of the node profile, a contribution score of the data point based on a time corresponding to when the data point was generated or updated. The system can then generate a confidence score of the value of the field of the node profile based on the contribution score of the at least one data point.
