Jointly optimizing word representations for lexical and sentential tasks with the C-PHRASE model

Pham, Nghia The; Kruszewski, German; Lazaridou, Angeliki; Baroni, Marco (ACL (Association for Computational Linguistics), 2015)

We introduce C-PHRASE, a distributional semantic model that learns word representations by optimizing context prediction for phrases at all levels in a syntactic tree, from single words to full sentences. C-PHRASE outperforms ...
There is no logical negation here, but there are alternatives: modeling conversational negation with distributional semantics

Kruszewski, German; Paperno, Denis; Bernardi, Raffaella; Baroni, Marco (MIT Press, 2016)

Logical negation is a challenge for distributional semantics, because predicates and their negations tend to occur in very similar contexts, and consequently their distributional vectors are very similar. Indeed, it is not ...
