Semantic Orientations of Words

These are the lists of words and their semantic orientations for Japanese and for English. You are welcome to use this resource fro a non-commercial purpose. The semantic orientation of a word indicates whether the word has positive meaning (e.g., beautiful, excellent) or negative meaning (e.g., dirty, inferior).
The semantic orientations were automatically computed using a lexical network. Although the orientation should originally be binary (positive or negative), our method assigned a real value in the range -1 to +1, where the words assigned with values close to -1 are supposed to be negative, and the words assigned with values close to +1 are supposed to be positive. The vocabulary was extracted from Iwanami dictionary for Japanese, and from WordNet-1.7.1 for English.

Each line corresponds to a word. The format of each line is:
word:reading:POS:semantic_orientation (for Japanese),
word:POS:semantic_orientation (for English).

English POS (part-of-speech) was symbolized as v for verb, n for noun, a for adjective, r for adverb.
Semantic orientations for other POSs were not computed.
