The increasingly large number of sensors and instruments in the oil and gas industry, along with novel means of communication in the enterprise has led to a corresponding increase in the volume of data that is recorded in various information repositories. The variety of information sources is also expanding: from traditional relational databases to time(More)
Replies posted in technical online forums often contain feedback to the author of the parent comment in the form of agreement, doubt, gratitude, contradiction, etc. We call this feedback-sentiment. Inference of feedback-sentiment has application in expert finding, fact validation, and answer validation. To study feedback-sentiment, we use nearly 25 million(More)
