Evaluating the morphological compositionality of polarity
Unknown words are a challenge for any NLP task, including sentiment analysis. Here, we evaluate the extent to which sentiment polarity of complex words can be predicted based on their morphological make-up. We do this on German as it has very productive processes of derivation and compounding and many German hapax words, which are likely to bear sentiment, are morphologically complex. We presen...
متن کاملDirect compositionality on demand1
This paper starts with the assumption that the expression saw everyone, as in John [saw everyone], is a constituent. After all, it can be coordinated, clefted, focussed, questioned, pronominalized, you name it. According to the hypothesis of Direct Compositionality, just like any constituent, this phrase must have a well-formed semantic denotation. But everyone (typically) takes scope over an e...
متن کاملDirect Compositionality on Demand ∗
The problem is that many natural language expression types lead a double life, simultaneously here and there, masquerading as a local lump but somehow interacting directly with distant elements. The two main examples discussed here are bound anaphora, in which an anaphor depends for its value on some distant binder; and quantification, in which some local element takes semantic scope over a pro...
متن کاملOn the Emergence of Compositionality
Compositionality is a hallmark of human language words and morphemes can be factorially combined to produce a seemingly limitless number of viable strings. This contrasts with nonhuman communication systems, which for the most part are holistic encoding a whole message through a single, gestalt form. Why does every human language adopt a compositional strategy? In this paper, we show that compo...
متن کاملOn compositionality and bidirectional optimization
In this paper we revisit the semantic principle of compositionality and argue that compositionality is bidirectional optimization. Underspecification approaches to natural language interpretation generally start with an underspecified or weak meaning, which is strengthened by contextual information. By contrast, the bidirectional optimization approach we advocate proceeds from the strongest pos...
