Continued stems and you can stems faster following a couple of characters was basically fundamentally eliminated acquiring a sample away from stems that we useful for the study.
Eventually (leads to Shape step three), we opposed the essential difference between American English and you will British English courses during the three most other analysis sets (in addition to aura conditions): content-100 % free terms, with the selection of the message-totally free terms and conditions available with Huges et al. , a comparable arbitrary stems employed for Shape 2, additionally the list of the fresh new 100 prominent urban agglomerations regarding world (from containing words instance Tokyo, Karachi, and Berlin.
