We also try to identify the most dominant LIWC word classes of the **data** by calculating the coverage of each word class for both lie and truth data. After that, we calculate the ratio between the two coverage scores to get dominance of each word class (Mihalcea & Strapparava, 2009). The calculation is performed on every **data** in the IDC corpus. As can be seen in Table 4, the result shows   (Pennebaker et al., 2007). Word classes with scores higher than 1 mean the classes are dominant in lie **data** and less than 1 mean the otherwise.
