Context dependent opinions

Popescu and Etzioni (EMNLP-05) used

constraints of connectives in (Hazivassiloglou and McKeown, ACL-97), and some additional constraints, e.g., morphological relationships, synonymy and antonymy, and

relaxation labeling to propagate opinion orientations to words and features.

Ding and Liu (2008) used

constraints of connectives both at intra-sentence and inter-sentence levels, and

additional constraints of, e.g.,  TOO, BUT, NEGATION, ….

to directly assign opinions to (f, s) with good results (> 0.85 of F-score).
