Figure 2
The figure shows six horizontal bar charts arranged in a grid, labeled “Topic 1” through “Topic 6”. Each chart displays “terms” on the vertical axis and “probability” on the horizontal axis, representing the most important terms for each topic. “Topic 1”: The horizontal axis ranges from 0.00 to 0.06 with increments of 0.01 units. The vertical axis lists the following terms from top to bottom: “bank”, “help”, “option”, “easi”, “plea”, “chang”, “updat”, “issu”, “back”, and “support”. The data from the bars are as follows: “bank”: 0.065, “help”: 0.055, “option”: 0.05, “easi”: 0.045, “plea”: 0.045, “chang”: 0.034, “updat”: 0.027, “issu”: 0.027, “back”: 0.026, and “support”: 0.023. “Topic 2”: The horizontal axis ranges from 0.00 to 0.07 with increments of 0.01 units. The vertical axis lists the following terms from top to bottom: “account”, “payment”, “merchant”, “custom”, “transact”, “time”, “money”, “receiv”, “show”, and “accept”. The data from the bars are as follows: “account”: 0.068, “payment”: 0.055, “merchant”: 0.052, “custom”: 0.042, “transaction”: 0.038, “time”: 0.035, “money”: 0.032, “receive”: 0.03, “show”: 0.027, and “accept”: 0.021. “Topic 3”: The horizontal axis ranges from 0.00 to 0.06 with increments of 0.01 units. The vertical axis lists the following terms from top to bottom: “hai”, “error”, “log”, “sign”, “link”, “fast”, “sir”, “nahi”, “raha”, and “account”. The data from the bars are as follows: “hai”: 0.062, “error”: 0.06, “log”: 0.055, “sign”: 0.044, “link”: 0.037, “fast”: 0.034, “sir”: 0.033, “nahi”: 0.025, “raha”: 0.023, and “account”: 0.021. “Topic 4”: The horizontal axis ranges from 0.00 to 0.30 with increments of 0.05 units. The vertical axis lists the following terms from top to bottom: “app”, “good”, “servic”, “bad”, “worst”, “applic”, “regist”, “experi”, “registr”, and “open”. The data from the bars are as follows: “app”: 0.31, “good”: 0.26, “servic”: 0.04, “bad”: 0.03, “worst”: 0.03, “applic”: 0.027, “regist”: 0.025, “experi”: 0.02, “registr”: 0.02, and “open”: 0.02. “Topic 5”: The horizontal axis ranges from 0.00 to 0.12 with increments of 0.02 units. The vertical axis lists the following terms from top to bottom: “offer”, “get”, “super”, “cashback”, “give”, “tri”, “even”, “abl”, “self”, and “even”. The data from the bars are as follows: “offer”: 0.115, “get”: 0.082, “super”: 0.06, “cashback”: 0.058, “give”: 0.05, “tri”: 0.03, “even”: 0.028, “abl”: 0.027, “self”: 0.023, and “even”: 0.021. “Topic 6”: The horizontal axis ranges from 0.00 to 0.16 with increments of 0.02 units. The vertical axis lists the following terms from top to bottom: “nice”, “busi”, “use”, “best”, “phone”, “phonep”, “work”, “pay”, “better”, and “aap”. The data from the bars are as follows: “nice”: 0.16, “busi”: 0.118, “use”: 0.10, “best”: 0.075, “phone”: 0.062, “phonep”: 0.062, “work”: 0.038, “pay”: 0.037, “better”: 0.023, and “aap”: 0.022.
