This article explores negation in Chinese on the basis of written and spoken corpora of Mandarin Chinese. The use of corpus data not only reveals central tendencies in language based on quantitative data, it also provides typical examples attested in authentic contexts. In this study we will first discuss negation variants in general terms, on the basis of which the focus will be shifted to the...

This paper describes our participation in the closed track of the *SEM 2012 Shared Task of finding the scope of negation. To perform the task, we propose a system that has three components: negation cue detection, scope of negation detection, and negated event detection. In the first phase, the system creates a lexicon of negation signals from the training data and uses the lexicon to identify ...

Inclusion of negation into logic programs is considered traditionally to be painful as the incorporation of full logic negation tends to super-exponential time complexity of the prover. Therefore the alternative approaches to negation in logic programs are studied and among them, the procedural negation as failure sounds to be the most successful and the most widely used. However, Constraint Lo...

This paper presents a survey on the role of negation in sentiment analysis. Negation is a very common linguistic construction that affects polarity and, therefore, needs to be taken into consideration in sentiment analysis. We will present various computational approaches modeling negation in sentiment analysis. We will, in particular, focus on aspects, such as level of representation used for ...
