For the present study, we made use of the subcorpora collected over the 9-year period 1995-2004 from Beijing (BJ), Hong Kong (HK), Singapore (SG), and Taipei (TW).
we made use of the financial news sections in these subcorpora, from which we extracted feature vectors for comparing similarity between a given target word and a thesaurus class, which is further explained in Section 4.3.
