TempoWordNet for sentence time tagging
TL;DR: To evaluate TempoWordNet, a semantic vector space representation for sentence temporal classification is used, which shows that improvements may be achieved with the time-augmented knowledge base against a bag-of-ngrams representation.
Opinion analysis: the effect of negation on polarity and intensity
TL;DR: The model is a compositional one, consisting in detecting and analyzing valence shifters such as negation which contribute to the interpretation of the polarity and the intensity of opinion expressions and its first implementation is described.
