Abstract(in English) This paper proposes three methods to extract pairs of verbs that mean time sequence of behaviors of people in the hospital from a corpus of blog entries about the hospital. The methods are (a) pattern-based extraction method, (b) probabilistic-model-based extraction method, and (c) subject-orientation-based extraction method. The method (a) and (b) use constraints to expressions between verb-pairs, in patterns and in bi-gram respectively. The method (c) uses constraints of both subjective semantic orientation of verbs (i.e. tends to patiant or doctor) and conjunctive expressions that mean time transition. These methods extract time sequential verb-pairs from the corpus by those constraints. As the results of experiments, the method (c) outperforms the methods (a) and (c) with extracting 397 corretcj pairs (precision = 0.353) from about 50,000 sentences in the corpus.
