I presented a couple of papers at this year's Socialcom . While I was presenting, the twittersphere was offering encouraging and puzzling feedbacks:<\/p>\n
The irony is that, during the \u00c2\u00a0coffee break right before my talk, I \u00c2\u00a0received few constructive feedbacks on how to structure my presentations and avoid having, as I often do, \u00c2\u00a0superficial and high-level slides for a *scientific* talk. Well, that's not the first time I get this feedback, and I accept it. However, I feel that many talks at conferences suffer from powerpoint karaoke syndrome<\/a> - to look \"right\" (like a proper scientist\/professional dude), one needs to recast a paper into slide format. Bad mistake, as The Great Simon L Peyton Jones would tell us<\/a>. Since I apparently like to suggest books, then let me say that, despite the title, \"Presenting to Win<\/a>\" is the best book on how to prepare and deliver presentations (it's for a business audience, but you can easily adapt it to your needs). \u00c2\u00a0Ideally, one should be able to give a talk without any slide - this way, i bet that karaoke presenters will be more likely to reach enlightenment and enter nirvana (provided that they spend 3 days to prepare a 15-minute presentation). If a smooth transition between powerpoint karaoke and nirvana is needed, then \u00c2\u00a0karaoke presenters \u00c2\u00a0might well try the \"Takahashi Method<\/a>\" \u00c2\u00a0- \u00c2\u00a0Lawrence Lessig has successfully used it (link to\u00c2\u00a0one<\/a> of his talks)\u00c2\u00a0and Steve Jobs was doing something similar for his keynotes.<\/p>\n Anyhooow :) \u00c2\u00a0this post isn't about presentation styles but about the two papers I presented :) Here is a quick abstract that summarizes them. Enjoy ;)<\/p>\n In the first paper<\/em> [pdf paper<\/a> slides<\/a>], we tested whether Twitter users can be reduced to look-alike nodes (as most of the spreading models would assume) or, instead, whether they show individual differences that impact their popularity and influence. One aspect that may differentiate users is their character and personality. The problem is that personality is difficult to observe and quantify on Twitter. It has been shown, however, that personality is linked to what is unobtrusively observable in tweets: the use of language. We thus carry out a study of tweets and show that popular and influential users linguistically structure their tweets in specific ways<\/strong>. This suggests that the popularity and influence of a Twitter account cannot be simply traced back to the graph properties of the network within which it is embedded, but also depends on the personality and emotions of the human being behind it. Also, in the second paper<\/em> [pdf paper<\/a> slides<\/a>], for a limited number of 335 users, we are able to gather personality data, analyze it, and find that both popular users and influentials are extroverts and emotionally stable<\/strong> (low in the trait of Neuroticism). Interestingly, we also find that popular users are \"imaginative\"<\/strong> (high in Openness), while influentials tend to be \"organised\"<\/strong> (high in Conscientiousness). We then show a way of accurately predicting a user's personality simply based on three counts publicly available on profiles: following, followers, and listed counts. Knowing these three quantities about an active user, one can predict the user's five personality traits with a root- mean-squared error below 0.88 on a [1,5] scale. Based on these promising results, we argue that being able to predict user personality goes well beyond our initial goal of informing the design of new personalized applications as it, for example, expands current studies on privacy in social media.<\/p>\n","protected":false},"excerpt":{"rendered":" I presented a couple of papers at this year’s Socialcom .
