Research Avenues of InquiryThe online reflection - Why does this matter?

• Volume – How did the conversation amplitude evolve over two weeks in February online?

• Sentiment – Where did negative sentiment originate and how did it evolve/spread? (keywords, people, and topics)

• Community – Who were the relevant actors? (Organizations, Customers, Users, Activists, Influencers, etc.)

• Post-level Performance – What types of posts and specific events instigated the issue online? (artifacts involved such as videos, photos, Facebook posts, tweets, etc)

How did the Copenhagen Zoo handle the event on social channels and how did the (social) media storm effect their presence? How did other organizations deal with the crisis? What made this incident different and how?

Channel Comparison• Twitter dominates 75% of total

chatter, while 21% is from Facebook Discussions

• Amplification: 50% of Tweets are retweets

Danish Subset• Media channels are more rich in

diversity • Facebook and Twitter only share

half the conversation• Only a quarter of all Tweets are re-

tweets

> Does mainstream media play a greater role for Danish society while, social media is dominant elsewhere in terms of quantity of discussion and breadth of dispersion?

Page 14: Marius - CBS Sentiment Workshop

Region and Language Detection

• 95% of the total conversation was detected to be in English.

• Almost two thirds of global activity came from the US (64%), followed by the UK (13%) and Netherlands (4%).

Automatic Sentiment Results

• Danish data tends to be much more neutral compared to the non-Danish data.

• Most of the negativity detected in Twitter for non-Danish data while most of the negative data occurs in Facebook for Danish data.

> Does this imply that Danes prefer Facebook to Twitter to express their ideas?

• Now 110K people “Were Here” on Facebook

• CPH Zoo is thus now the 7th most checked-into place in Denmark

Page 30: Marius - CBS Sentiment Workshop

Initial Findings

Overall• Twitter offered a more direct reflection of events, in terms

of volume and sentiment• Twitter also demonstrated a more drastic reaction to

network prestige factors from activists and celebreties• Automatic sentiment on Radian6 is neutral-heavy, often failing

to detect negative sentiment,• The dominance of English-language countries and the

Twitter channel went hand-in-hand (perhaps along with mainstream spin).

• The mechanisms on Facebook allow a dichotomy from crisis situations by yielding negative sentiment in terms of comments and posts, while simultaneously experiencing unprecedented growth in positive signals (such as fans and likes, as well as buzz and check-ins).

Page 31: Marius - CBS Sentiment Workshop

Danish Comparison

Contrast with Danish Subset• Mainstream media plays a larger role

as opposed to higher proportions of online debate on social channels elsewhere

• Re-tweets levels are relatively small and social media may be used social media more to express oneself rather than to share information.

• Negative sentiment was detected more strongly on Facebook
