Growing a lexicon from seeds

An axis for the ferry reviews

A deckhand reports being irritable for the whole week, with no single trigger, after being furious when the manifest went overboard for an hour. Which pairing of affect classes fits the two states?

In the dimensional view of emotion, what do the valence, arousal and dominance axes measure, and which word sits high on arousal and low on valence?

A word embedding is $(5, 3)$ and a semantic axis built from positive and negative seed centroids is $(2, 4)$. Compute the cosine between them, the word's polarity score, rounding to three decimals.

The semi-supervised lexicon induction family exploits syntactic coordination as a polarity cue. Which claim about the cue is correct?

A rule-based classifier counts weighted positive evidence $f^+ = 7$ and weighted negative evidence $f^- = 1$ in a review, labeling positive when $f^+/f^- > 1.5$, negative when $f^-/f^+ > 1.5$, and neutral otherwise. Compute the value of $f^+/f^-$, rounding to three decimals.
