Previous treatments of quadrotor vehicle dynamics have often ignored known aerodynamic effects of rotorcraft vehicles. At slow velocities, such as while hovering, this is indeed a reasonable assumption.

We extend the model to include applied torques, but the torque must be calculated analytically through some other means. We show the numerical solution of the example of a rigid body with two rockets on each side of an ellipsoid, aimed to provide

Sentiment Analysis of Twitter Data - Columbia University

Sentiment analysis has been handled as a Natural Language Processing task at many levels of gran-ularity. Starting from being a document level classi-fication task (Turney, 2002; Pang and Lee, 2004), it has been handled at the sentence level (Hu and Liu, 2004; Kim and Hovy, 2004) and more recently at

Extracting consumer or public sen-timent is thus relevant for fields from marketing to politics. The simplest version of sentiment analysis is a binary classification task, and

Aspect-based sentiment analysis is a fine-grained sentiment classification task. Re-cently, graph neural networks over depen-dency trees have been explored to explicitly model connections between aspects and opin-ion words. However, the improvement is lim-ited due to the inaccuracy of the dependency parsing results and the informal expressions

Aspect-based sentiment analysis aims to iden-tify the sentiment polarity of a specific aspect in product reviews. We notice that about 30% of reviews do not contain obvious opinion words, but still convey clear human-aware sen-timent orientation, which is known as implicit sentiment. However, recent neural network-
