A system and method and computer program product for cognitive recording and sharing of live events. The system includes: a sensing and transmitting device that can sense the biometric signatures of an individual; a processing unit that analyses the sensed signal and initiate a set of actions; a recording device or the like to record the event; and a networked sharing device configured to subsequently share recorded event content. The system further identifies individuals' pre-cognitive inputs and additional external and internal factor input signals that are precursors to cognitive affirmation of an emotional response. These inputs will be identified, correlated, and used in training the system for subsequent identification and correlation between input factors and resulting emotional state. External factors may include: recognized emotional states, biometric inputs, and/or precognition inputs of other individuals in proximity to the subject individual. Other factors may include an individual's context.

Cognitive recording and sharing

According to one embodiment of the present invention, a level of a first hierarchy and a second hierarchy of data attributes is determined where the first hierarchy and the second hierarchy share the determined level and each subordinate hierarchical level. The embodiment further removes from a set of tuples of a database operation at least one tuple that lacks corresponding data in a data source based on the tuple containing elements corresponding to non-intersecting sets of attributes at the determined level. Embodiments of the present invention include a method, system and computer program product for reducing tuple sets in substantially the same manner described above.
