QUIZ 3 WRITTEN WORD AND ANALYSTICS
Question 14
The "Big Social Data Analytics in Journalism and Mass Communication" article compared two “big data” text analysis methods: dictionary-based analysis, perhaps the most popular automated analysis approach in social science research, and unsupervised topic modeling, one of the most widely used algorithms in the field of computer science and engineering. By applying two “big data” methods to make sense of the same dataset—77 million tweets about the 2012 U.S. presidential election—the study provided a starting point for scholars to evaluate the efficacy and validity of different computer-assisted methods for conducting journalism and mass communication research, especially in the area of political communication.
What was the conclusion of the study?
Select one:
a. Dictionary based analysis proved to have more false positives and was therefore less reliable.
b. The dictionary based analysis was superior for analyzing the entire corpus.
c. Significant errors were found in results generated by both methods.
d. Unsupervised topic modeling provided less accurate information and was unreliable. e. The LDA method gave more certain metrics and was more reliable.
Question 15
The C4RSINET article about the downside of big data states the amount that the United States loses annually to a broad spectrum of intellectual property crimes (data theft) equates to an estimated loss of 750,000 jobs nationally each and every year as well. Yet, multiple industry analysts have forecast a coming period of rapid data growth and one quantified it by saying they expect data to double every two years. They estimate there will be 140,000 to 190,000 unfilled positions in this field within the U.S. in 2018. Think about that talent shortage and the impact it will have on the intelligence community!
TRUE OR FALSE: The amount of data is expected to reach 40 terrabytes by 2020? Select one:
True
False
