This paper reports on experiments with a newly available sentiment classification test collection for Chinese. Detection of negation during training and classification is shown to improve the accuracy of character-based classification for the semantic orientation of individual Chinese words. Using the resulting classifier for unknown words resulted in substantial improvements in classification ...

The problems of the meaning and function of negation are disentangled from ontological issues with which they have been long entangled. TIle question of the function of negation is the crucial issue separating relevant and paraconsistent logics from classical theories. The function is illuminated by considering the inferential role of contradictions, contradiction being parasitic on negation. T...

We study the usage of negation in JSON Schema data modeling. Negation is a logical operator rarely present type systems and schema description languages, since it complicates decision problems: many software tools, but also formal frameworks for working with Schema, do not fully support negation. This motivates us to whether actually used practice, which aims, could—in principle—be replaced by ...
