1 Collective Emotions in Cyberspace Short review of Cyberemotions project results In the name of CYBEREMOTIONS Consortium Janusz Hołyst, Project Coordinator, Warsaw University of Technology,

2 Plan Emotions, cyberemotions, collective emotions and collective cyberemotions Cyberemotions Project structure Main results of various Project layers: - data collection and classification - collective character of cyberemotions and data driven models of cybercommunities - project ICT outputs

3 There is no agreement what emotions are but they are important for our life !

4 Negative stimuli negative emotion forces ACTION And they can be useful for fast reactions !!!

5 Collective effects do matter.... also for emotions !

6 Collective emotions

7 Satellite meeting at ECCS'12 Emotion in cyberspace ?

8 8 Twitter Revolution Pic. Arab Spring in Egypt 2011 congratulations Egypt the criminal has left the palace – a tweet from Egyptian protest leader Wael Ghonim. Twitter can help organize. Facebook can help get the word out. YouTube provides evidence. Over the past few years, we've seen that social media can be a powerful tool in assisting revolutions in countries. - Cheryl Aguilar, EthnoBlog Collective emotions in cyber-communities ? Pic.

10 Expected impact of CYBEREMOTIONS new classes of realistic models of emotionally reacting E-users new kind of intelligent self-adapting programs, cyber-tutors, cyber-advisors for e-communities (long time scale) to create theoretical background for the development of the next generation emotionally-intelligent ICT services using universal methods of complex systems (long time scale). CYBEREMOTIONS = data gathering + complex systems methods + ICT outputs Main aims of Cyberemotions Project were to understand the process of collective emotions formation in e-communities

13 WP3 created sentiment analysis software - Used for research and for light displays on the London Eye during the Olympics SentiStrength

14 EMG (smiling, frowning) EKG (heart rate) EDA (sweating) Continuous recording of psychophysiology during participation in a forum discussion

15 Data collected by Wolverhampton group BBC Forum BBC Religion and Ethics and World / UK News message boards starting from the launch of the website (July 2005 and June 2005 respectively) until the beginning of the crawl (June 2009). #comments 2,474,781 #users 18,045 # threads97,946 Digg The analysis spans the months February to April 2009 and consists of all the stories, comments and users that contributed to the site during this period. The resulting dataset contains approximately 1.9 million stories, 1.6 million comments and 800 thousand users. Blog06 crawl of approximately 100,000 blogs and which spans 11 weeks, from 06/12/2005 to 21/02/2006", i.e. the dataset contains webpages from 100,000 different blogs (more than 3 million webpages). The blogs are from all over the world, although there is an emphasis on English content #comments 242,057#discussions million comments Detection of collective emotions in cyber-communities

16 Emotions (emotional valence e ={ +1,0,-1}) We define an emotional cluster of size n as a chain of n consecutive messages with similar sentiment orientations (i.e. negative, positive or neutral). Emotional clusters Detection of collective emotions in cyber-communities

17 Emotional homophily of e-communities The presence of a longer cluster of coherent emotional expressions increases a possibility to follow the cluster by a comment with the same emotion. Conditional probability for cluster growth increases as a power-law with cluster length.

19 19 p(e|e) Characteristic exponents α decay linearly with conditional probability of emergence of clusters of size two 2. Collective emotions in cyber-communities Minority emotion (less frequent) posses larger value of α - the growth probability is more dependent on cluster size Week interaction Strong interaction Rare emotions create stronger ties

20 20 Negative emotions as a fuel for discussion in cyber communities Negative emotion Better not to be here … A negative emotion results with escape response in real world What about the Internet ?

21 21 | | absolute value of the average emotion valence of the first 10 comments Lenght of a thread Number of comments in a thread Average length of a thread as a function of the absolute value of the average emotion valence of the first 10 comments Emotional beginnings of the threads, whether positive or negative, usually lead to longer discussions Negative emotion as a fuel for discussions


23 WP6/JSI:Emotional Bots can induce collective mood [Ref3]: B. Tadic and M. Suvakov, Arxiv: (2013) joyBot polarizes network of Agents (red links indicate positive emotion messages), while miseryBot induces excess of negative emotion messages (carried by black links ) [Ref3] Simulations revealed how Agents collective emotion polarizes under the influence of positive/negative emotion Bots [Fig.] Bot's impact on Agents can be measured; It relies on the network structure (which propagates emotion among Agents) and on the self-organized nature of the dynamics (which enhances correlations)

24 WP6/JSI: Agent-Based Model of Chats with Emotional Bots Ref.: V. Gligorijevic, M. Suvakov and B. Tadic, DRAFT (2013) Experimental data: Users group according to their similarity in emotional communications with Bot (5 communities, left); More cohesive groups appear when they are placed in an interactive environment (simulated, right) [Ref.] Agent-Based Model with emotional Agents + Moderators + Bots developed & validated Agents designed with certain 'human' attributes ( inferred from the empirical data ) Experimental emotional Bot used as input: response of Agents simulated

31 Selected project achievements Emotional responses can be predicted from observation of sentiment fluctuations in physiological and Twitter data. Asymmetry is crucial for emotion animations in facial expressions. Sentistrength program used during Olympic Games to monitor daily moods in UK (display at London Eye). Developed affective bots are capable to communicate with humans. Emotions can be crucial for leaving of Open Source Community by their active members (including project leaders). Chat Bots developed for data driven models of e-communities can propagate negative/positive emotions and polarize channel moods. Chat Bots can lead to social exclusion of e-community members. Universal tools developed for automatic analysis and visualisation of emotion propagation in social data.

32 Conclusions. We demonstrated that collective emotions do exist in a broad class of e-communities Collective emotional dynamics is vital for the efficiency and survival of e-communities The current technology makes possible to create bots that can influence human emotions Understanding the role of and strategic use of cyberemotions will be crucial for the future society because of technological, economical and political issues.

33 More results will be presented at next presentations, posters and CyberEmotions video lectures: sPW/videos
