nDTCM is used to organize the data in social streams. We believe the meaningful semantic features discovered by nDTCM can also benefit the representation of social streams.
Using nDTCM as a building block can further analyze sophisticated structures/patterns in social streams.
Each data point is represented as one line in plain format, splited by space, accordingly denoted as EPOCH #PARTICIPANTS PARTICIPANTS(split by commas) #DISTINCT_WORDS WORD:FREQUENCY 15 5 0,1,2,3,4, 18 14:1 43:1 45:1 31:1 40:1 49:1 6:2 7:2 33:1 34:2 22:1 2:1 8:1 32:1 26:1 27:2 53:1 23:1
