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.

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.
