| Generating Topic-Specific Lexicons | Extract all syntactic contexts of clue words |
| Generating Topic-Specific Lexicons | 3.1 Step 1: Extracting syntactic contexts |
| Generating Topic-Specific Lexicons | First, we identify syntactic contexts in which specific clue words can be used to express |
| Qualitative Analysis of Lexicons | Because our topic-specific lexicons consist of triples (clue word, syntactic context , target), they actually contain more words than topic-independent lexicons of the same size, but topic-specific entries are more selective, which makes the lexicon more focused. |
| Quantitative Evaluation of Lexicons | D: the number of syntactic contexts per clue |
