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

Yesterday we began our look back at the year in semantic technology here. Today we continue with more expert commentary on the year in review:
Ivan Herman, W3C Semantic Web Activity Lead:
I would mention two things (among many, of course).
- Schema.org had an important effect on semantic technologies. Of course, it is controversial (role of one major vocabulary and its relations to others, the community discussions on the syntax, etc.), but I would rather concentrate on the positive aspects. A few years ago the topic of discussion was whether having ‘structured data’, as it is referred to (I would simply say having RDF in some syntax or other), as part of a Web page makes sense or not. There were fairly passionate discussions about this and many were convinced that doing that would not make any sense, there is no use case for it, authors would not use it and could not deal with it, etc. Well, this discussion is over. Structured data in Web sites is here to stay, it is important, and has become part of the Web landscape. Schema.org’s contribution in this respect is very important; the discussions and disagreements I referred to are minor and transient compared to the success. And 2012 was the year when this issue was finally closed.
- On a very different aspect (and motivated by my own personal interest) I see exciting moves in the library and the digital publishing world. Many libraries recognize the power of linked data as adopted by libraries, of the value of standard cataloging techniques well adapted to linked data, of the role of metadata, in the form of linked data, adopted by journals and soon by electronic books… All these will have a profound influence bringing a huge amount of very valuable data onto the Web of Data, linking to sources of accumulated human knowledge. I have witnessed different aspects of this evolution coming to the fore in 2012, and I think this will become very important in the years to come.
There’s been a lot of attention given to the issue of prescription drug abuse, in the wake of violent crimes such as one last year that left four people dead in a pharmacy shooting in Suffolk County, New York. A recent study from the Workers Compensation Research Institute also shows that prescription drug abuse is the fastest growing drug problem in the United States, with over fifteen thousand people dying last year from an overdose. And, the U.S. Senate in late May approved an amendment to reclassify drugs that contain hydrocodone, a highly-addictive substance found in Vicodin and Lortabas, among other drugs, as Schedule II substances, while giving law enforcement more tools to monitor distribution of such drugs and also decreasing access to them for non-medical purposes.
What, you may ask, does any of this have to do with semantic technologies? Dr. Amit P. Sheth, Wright State University Kno.e.sis Ohio Center of Excellence in Knowledge-enabled Computing director and LexisNexis Ohio Eminent Scholar, and Dr. Raminta Daniulaityte of the school’s Center for Interventions, Treatment and Addictions Research (CITAR), have a ready answer : PREDOSE, an application for understanding pain-killer drug abuse through the semantic analysis of social media conversations. More specifically, it’s automated data collection and analysis tools to process web-based data to determine the knowledge, attitudes, and behaviors of addicts, related to buprenorphine, OxyContin and other pharmaceutical opioids. It’s a National Institutes of Health (NIH)-funded project created by a partnership between Kno.e.sis and the CITAR.
Our own Jennifer Zaino recently reported that semantic social web application Twitris, a program at Wright State University, was tackling coverage of the Occupy Wall Street movement as well as the presidential election. Now Twitris will be busier than ever: “Wright State University has been assigned a patent for core analysis methods used by the Twitris system.” Read more
