... examples that the
shortest-path method can assign a non-zero orien-

signed for 2 seed words, the method is extended
to use the average shortest-path ... adjectives for comparison of methods. The
result in Table 4 also shows that the global optimiza-
tion of the spin model works well for the semantic
orientation extraction.

grading. In particular, we carry ... performance of the
