What makes airline passengers happy?

A few of the high-profile carriers, that are currently scoring well, may be dangerously relaxed about their service and may soon fall out of grace, and a few contenders are posed to take their place. It is possible that observed trends in perceived service may be the best predictors for relative changes in passenger satisfaction, overall rating, loyalty and so on and forth. These are some the generalizations emerging from analyzing just the qualitative data, in the form of 20000 passenger reviews, in free-text, covering 22 carriers: Air China, Air France, All Nippon Airways, American Airlines, British Airways, Cathay Pacific…

All your topics are belong to us

Jodel is undoubtedly one of the most interesting online communities at the moment. For those of you who have not already become addicted to the Jodel app, Jodel is an anonymous and localized community where users post and react to real-time updates (both text and photos) about anything and everything that is going on in the local community right now. Although the intended target audience is primarily university students, the appeal of anonymous real-time localized information has spread wide outside the student community. We at Gavagai love interesting text data, and Jodel seems like a veritable goldmine of information to…

Gavagai’s Top List of “Movers-and-Shakers” Shows Worry about Global Economy is on the Rise

Gavagai’s Movements list shows the movers-and-shakers of all of the thousands of targets being tracked in our system. The list is updated with regular intervals and is a good indicator of things to look out for. Currently “Global Economy”, a target that tracks various sentiment like worry, fear, positivity and so on, is showing a significant increase in the worry and violence sentiment categories (violence is shown above as VPI in the screen shot from our internal admin GUI). What is the cause of this? To understand the reasons for the current spike we have a number of options. We…

Gamergate tweets and sentiment analysis

The heated #GamerGate debate raging in social media in recent weeks has recently emerged into editorial media as well. A dive into the actual data done by Brandwatch and published by Newsweek last week found that indeed more of the material published on Twitter under that hashtag is vitriolic and confrontative rather than a discussion on media ethics. Newsweek writes: “If GamerGate is about ethics among journalists, why is the female developer receiving 14 times as many outraged tweets as the male journalist? … The discrepancies there seem to suggest GamerGaters cares less about ethics and more about harassing women.”…

Greek Election Tomorrow!

The Euro and the European currency union is the major topic of the second Greek parliamentary elections of this Spring, to be carried out tomorrow, on Sunday, June 17. Ethersource has been reading Greek-language social media for the past few weeks. Our prediction: ND will be leader in number of votes one needs more than tallying frequency of mention or simple assessment of positive vs negative sentiment to use social media for predicting electoral outcomes   We at Gavagai have been following party politics in the Greek social media for the past few weeks and have found – as have…

A Minute-by-minute Popularity Contest – Loreen versus Danny

Despite the fact that the Swedish part of the Eurovision Song Contest final was broadcast live, as a TV viewer it was impossible to get a sense of just how popular the artists were at a given point in time. Having access to Ethersource made sifting out meaningful blog posts and Tweets in real-time a breeze! Below are two graphs outlining, minute-by-minute, the popularity of the two top contestants as expressed in Swedish on-line social media for the day of the final (click the image for a larger version). Note that the popularity score of Loreen’s reaches higher during her…

Fabulous Fest Forecast by Gavagai

Sweden’s contribution to the Eurovision Song Contest this year has been decided in yesterday’s finale with ten contestants. The winner of 2012 year’s Swedish music fest Melodifestivalen is Loreen, with the song “Euphoria”, which landed almost 700000 call-in votes from the at-home TV audience. Using the Ethersource technology, Gavagai followed the on-line sentiment towards all contestants throughout the lead-up to the event. We are pleased to note that Gavagai’s forecast of the results based on expressions of appreciation in blog posts and tweets which was published in the paper edition of Svenska Dagbladet (SvD) in the morning prior to the event –…

Artist Lars Vilks Attacked. Again.

At 6:45 pm, less than a minute after the news broke on Twitter, Ethersource picked up the first aversive signal relating to tonight’s attack on Lars Vilks. (We’ve covered him previously on this blog). This time, elements in the audience threw eggs at him during an evening lecture in Karlstad. Of the major news outlets, the branch of Swedish Radio located in Karlstad was the quickest in publishing the news, putting it on their national web site at 7:43 pm (SR). The other players were roughly 30 to 45 minutes behind (DN, SVD, SVT). Having Ethersource doing real-time attitudinal analysis…

Ethersource as a tool for data-driven journalism: the case of the fading interest in Julian Assange

The world has taken a keen interest in Wikileaks founder Julian Assange for quite some time now. A recent article in a leading Swedish newspaper, Svenska Dagbladet, claims that the general interest in Assange and Wikileaks has faded, an assertion based on frequency counts of search queries for Assange obtained from Google Trends. By consulting Ethersource, we can confirm the trend at large. Now, there’s only so much to be said based on frequency counts of search queries. The fact is that people are still showing a clear interest in Assange. However valid the claim that the general public’s interest…

Tracking Swedish political sympathies in social media

This Fall has been more eventful than many in Swedish politics, in spite of no real political events taking place. The recently elected leader of the Social Democratic Workers’ Party has been tangled into a mess of possibly excessive and in any case overcompensated housing allowance remuneration. Our take: Centerpartiet is fading out of view in spite of a newly elected and positively received leader. The Social Democrats have become the focus for negative sentiment in the blogosphere, even to the point of distracting the established negative sentiment visavi Sverigedemokraterna. A leadership change in the Social Democratic party is imminent.…

Gavagai analyses the Greeks’ attitudes toward the cancelled referendum and the Eurozone

Greece has now officially scrapped plans for a referendum on the Euro bailout plan. Our research shows that a small majority (53%) of Greeks did not want the referendum, the exact subject matter and formulation of which remains unspecified and unclear. In our view, a majority (79%) of Greeks wants to remain in the eurozone. We note, however, that willingness to keep the Euro falls dramatically when the issue is raised in the context of austerity measures, which leads us to believe that if a referendum – on whether to remain in the Eurozone subject to harsh austerity conditions –…

Greece: Politics, Economics, and Rowdy Behaviour separated

Many of us are trying to keep track of what is going on in Greece these days. We will have reason to give you more news flashes of how events in Greece are being narrated and reported – here is a first peek at results from our ongoing monitor. This monitor is based on English-language reports, chatter, tweets, blog and forum posts on the Greek crisis. Noticeable is that there is a clear spike in our vpi signal in mid-October (blue ring). This signal – the violence propensity index – indicates violent sentiment. The news reports we have collected from…

Analysis of buzz, hatred, and associations during the unraveling of Håkan Juholts accommodation reimbursements affair

In this post, we analyze the mention frequency, strong negative sentiment or hatred and terminology associated with the leader of the Swedish Social Democrats, Håkan Juholt, during the unraveling of his accommodation reimbursements affair. The analysis is made on the Swedish blogosphere between October 1 and 19, 2011, by using Ethersource technology and our proprietary associations engine. The short version of the story is: Juholt went into the accommodation affair in early October with a fairly low buzz in the blogosphere, and a reasonable level of strong negative sentiment or hatred expressed towards him considering he is a leading politician…

The killing of Mashaal Tammo through the eyes of Arabic social media

In this post, we show three things: The possibility of using Ethersource to monitor Arabic social media to detect violent on-line chatter, and to identify the real-worlds events underlying the resulting signal. On the evening of Friday, October 7 2011, Kurdish opposition politician and founder of the Kurdish Future Movement Party Mashaal Tammo was shot dead by masked men in his home, in north eastern Syria. His killing was soon attributed to the regime of Syria. The next day, Saturday, October 8, the funeral party for Tammo, with 50,000 to 100,000 attendants, turned into the largest gathering of protesters since…

Beyond “Positive” and “Negative” – Gavagai looks beyond the first take at sentiment analysis

“Sentiment analysis” as a research field took its time to become an overnight success. From being a concern of behavioural psychologists and philologists, about seven years ago, at the 2004 AAAI Spring Symposium on “Exploring Attitude and Affect in Text: Theories and Applications”, it entered stage as an application for language technology and information access technology. The commercial potential is self evident and straightforward, the pickings are easy and marketable, and the technology is fun for engineers to play with (way more fun than plain old topical search engines). The field has rightly exploded with commercial activity. So far, applications…

How are you Sweden? Happier AND more uncertain during weekends.

We’re using Ethersource to monitor the mood of the Swedish blogosphere in terms of positivity, negativity, uncertainty, and an index we call Positivity Propensity Index (PPI). The graphs below show two particularly interesting things. Positivity (as in PPI) is cyclic on a weekly basis; Swedes are happier during weekends (Image 1). We all knew this, but it’s good to get it on ink. At the same time, Swedes are more uncertain during Fridays, Saturdays, and Sundays, than they are during the rest of the week (Image 2). Image 1 shows the positivity, negativity, and PPI for a three week period in…
