The project will focus on the creation of novel technology that can understand ‘semantic and social patterns’.” Read more

Twitris Measures Sentiment About Indian Elections

07-1396854734-twitter-analysis-1

Oneindia News recently shared a new case study of how Twitris was used to measure sentiment about the current elections in India. The article begins, “Based on 900,000 tweets collected from 15 states about three major political parties (BJP, Congress and AAP), our analysis shows how people talked about and reacted to each political party. Using Twitris, their Collective Social Intelligence platform, the researchers at the Ohio Center of Excellence in Knowledge-enabled Computing (Kno.e.sis) at Wright State University processed each tweet to compute sentiment about the mentioned political party. One parameter to measure popularity is to check which political party gets most positive sentiment or least negative sentiment. Just counting negative (or positive) sentiments on a politician provides, as in this Deccan Herald story, provides little useful information about the state of electorate.” Read more

Twitter Introduces Data Grants

Twitter

Last week, Raffi Krikorian of Twitter announced that Twitter is “introducing a pilot project we’re calling Twitter Data Grants, through which we’ll give a handful of research institutions access to our public and historical data. With more than 500 million Tweets a day, Twitter has an expansive set of data from which we can glean insights and learn about a variety of topics, from health-related information such as when and where the flu may hit to global events like ringing in the new year. To date, it has been challenging for researchers outside the company who are tackling big questions to collaborate with us to access our public, historical data. Our Data Grants program aims to change that by connecting research institutions and academics with the data they need.” Read more

Moviegoer Social Sentiment: Big Data Analysis For Big Business

Like lots of other families over the recent Thanksgiving weekend, we made our way to the movies. Our choice: Life of Pi. We’d highly recommend it, and according to the IBM Social Sentiment Index, as applied to Moviegoer Social Sentiment over the holiday weekend, so too would a lot of other folks. It earned a 90 percent positive rating.

IBM has engaged in the social sentiment index pursuit in some other endeavors – using its advanced analytics and natural language processing technologies to analyze large volumes of social media data, it had another recent take on Black Friday, for example. It tallied up that shoppers expressed positive consumer sentiment on promotions, shipping and convenience as well as the retailers themselves at a three to one ratio (see our story here for other takes on semantic tech weighing in on the holiday shopping season).

It’s also applied its social media analysis smarts to studying births of trends (cycle chic is on the rise), and which tennis player was on the hearts and minds of the crowd at the U.S. Open (Novak Djokovic and Laura Robson winning the love, with positive sentiment scores at 90 percent or better).

Gnip Launches Commercial Access to Every Public Tweet Ever

Jolie O’Dell of VentureBeat reports that on Wednesday, “Gnip launched its Historical PowerTrack for Twitter, which will give developers the ability to search, find, analyze, and compare all the tweets ever written, even ones written before the developer in question started scraping Twitter. It’s the same level of access the Library of Congress got when it started archiving and storing all Twitter data, but this time, it’s commercially available. ‘There are a handful of companies that have collected some portion of Twitter data,’ said Gnip COO Chris Moody in a meeting with VentureBeat yesterday. ‘We were able to do it because we partnered with Twitter on it’.” Read more

London Eye Lights Up With Olympics Sentiment

As the opening ceremony for the London Olympics gets underway tonight, sentiment on the event can be gauged nightly in a big way: The EDF Energy London Eye Ferris Wheel, the largest in Europe, will turn colors depending on the sentiment analysis of tweets coming out of the U.K. mentioning the Olympics.

 

Sosolimited, an art and technology studio helmed by three MIT grads, has written software to capture these tweets and then uses sentiment analysis algorithms to assess their emotional content. SentiStength, a program that itself hails from the U.K., is reportedly the source of the algorithms. During the day, that will be charted on a large LED next to the London Eye, and each night the data will guide the sequence of a visual lightshow around the Eye.  “That data is played back out across full color architectural lighting fixtures around the Eye and with large ground based search beams,” according to a blog posting from founder Justin Manor. It’s been reported that yellow will be the dominant color to express positive sentiment, while purple will showcase negative sentiment.

Expectations: Early on, at least, probably a lot of yellow, even if traffic is a nightmare, from a lot of outraged Brits who want to have their say over Mitt Romney’s comment about how well-prepared the city is for the Games.

FirstRain Spotlights Semantics Across Domains

Enterprises using semantic technology often come up against a problem: Not being able to scale their approaches across domains.

“We hear a lot about semantic approaches that work great when targeted to a domain – for example, you can train up an NLP engine for the hotel industry domain that knows ‘thin’ is a bad word when applied to it,” explained YY Lee, chief operating officer at customer intelligence vendor FirstRain at the recent SemTech conference in San Francisco. “But the amount of the business world to be potentially covered by semantic techniques – that limitation to train for specific domains cannot scale.”

Yandex Partners With Topsy To Offer Real-Time Social Search, Just In Time For Russian Elections

Russia’s leading search engine Yandex – which is collaborating with U.S. search engine giants in implementing schema.org and which last week partnered with Twitter to post tweets in real-time in search results – has made another deal this week: It’s working with Topsy Labs to enable social search.

Real-time search and analytics provider Topsy’s indexing and live-ranking will help Yandex search in Russia and Turkey identify and extract fresh and relevant results from social media sources. Vipul Prakash, Topsy’s co-founder and Chief Technology Officer, says Topsy’s corpus consists of about 100 billion tweets, and the page links and media referred to in them, all time-stamped and authorship-explicit. It does some amount of synthetic tagging to extract the topic from the tweet to make the topic searchable, as well as performs classification of content, where there’s more text to play with, for links referenced in tweets. It understands that the author is distinct from what is being discussed and who is referring to whom in postings, which feed into its graph of influence that ranks links in search results based on the influence of people talking about those links. That includes a global rank of a user independent of topic and terms and also keyword-level ranks based on what was in a tweet when they got attention for it.

Because it has such histories of people to extract from that a robust understanding of their network credibility, including how they’ve received attention from others in the past, Topsy does a really good job of getting rid of spam, Prakash says. That’s a particularly useful capability to bring to Yandex to weed out suspicious social tweets in advance of the controversial Russian presidential elections getting underway this weekend, as reports have noted that fake Twitter accounts have been created to drown out opposition voices by flooding Twitter’s hashtag service function. “In Russia there is a lot of precedent for political activism like that,” he says. “If something points out a problem with a candidate, they will have people start spamming it so you can’t actually find the real piece of information.”
