  16. Google Flu Trends • Tool released by Google researchers, in 2008, for predicting how many people were getting sick with the flu in different places around the world. • Google Flu Trends uses aggregated Google search data to estimate current flu activity around the world in near real-time. • At the time, the tool could predict the likely number of cases in parts of the United States 10 days before the Centers for Disease Control and Prevention (CDC) could.

  25. Delaycast • Helps you obtain reasonable estimates of the flight delays you may experience. • “On-time prediction engine” – estimates are based on factors such as the airline, flight origin and destination, developing trends, holidays, date and time of the flight and so on. • Flight delay predictions are produced by the models and thus aren’t 100% accurate. Nevertheless, the additional insight provided beyond the airlines schedules should come in handy for most of the travelers. A.Frank

  33. Sentiment Analysis (Opinion Mining) • Refers to a broad area of data analysis, natural language processing, computational linguistics and text mining. • Sentiments or emotions get expressed through ideas, opinions, criticisms, and sarcasm. It is measured against what’s positive, what’s negative, and what remains neutral. • The attitude of an author may be their judgment or evaluation, their affective state (i.e., the emotional state of the author when composing) or the intended emotional communication (i.e., the emotional effect the author wishes to have on the reader). • Sentiment Analysis is exceptionally challenging as computers are very poor at understanding irony, subtext, implicit context and all kinds of other linguistic constructs that a human easily comprehends. A.Frank

  35. The Stock Sonar • Continuously scans the traditional and social media, bringing up timely insights to the attention so as to be able to see the earliest ripples before the wave hits. • It provides a one-glance quantified assessment of the financial, news and social media sentiment relevant to stock market analysis. • Enables rapid, timely and informed trading decisions based on real-time and historical media sentiment on specific companies and sectors. • The Stock Sonar leverages advanced information extraction technologies developed by its parent company, Digital Trowel.
