For domain specific and general sentiment lexicons we explored different word quantity thresholds: {1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000} and report the results with each of them (see Figure 2 and 3).
we denote by ) , , ( we can define the main measure in the current experiment: This is the difference between the accuracy obtained with the lexicon L and baseline lexicon FL, during the transfer from source domain S to target domain T. we also use the averaged variant of this measure: In our case 9  D .
