Distinguishing between authentic and fictitious user-generated hotel reviews

Abstract

Distinguishing between authentic and fictitious user-generated hotel reviews

Trust in online hotel reviews across review polarity and hotel category

“…This suggests that users can be skeptical about reviews that offer overly specific details. Perhaps, the veracity of such informative reviews is doubted because they are viewed as being written by individuals who are too eager to convince (Banerjee et al, 2015).…”

“…Users appear to trust reviews that are congruent with their expectation-in this paper, positive reviews for luxury hotels, and negative reviews for budget hotels-easily without basing their decision-making adequately on their perception. This might not always be wise as several reviews available on the Internet could be biased (Banerjee et al, 2015;Pal & Chua, 2016).…”

Don't be deceived: Using linguistic analysis to learn how to discern online review authenticity

“…The initial pool of 83 variables was filtered through information gain (IG) and chi-squared (v 2 ) feature selection techniques. Only those variables with nonzero IG and nonzero v 2 values were selected for further investigation (Banerjee, Chua, & Kim, 2015;Forman, 2003;O'Mahony & Smyth, 2009). 1 Second, the feature-selected variables were further tested using independent samples t-tests to identify a filtered set of linguistic variables that differed between authentic and fictitious reviews.…”

“…The initial pool of 83 variables was filtered through information gain (IG) and chi‐squared (χ 2 ) feature selection techniques. Only those variables with nonzero IG and nonzero χ 2 values were selected for further investigation (Banerjee, Chua, & Kim, ; Forman, ; O'Mahony & Smyth, )…”

“… The comparison of the proposed classification approach with existing baselines, and the detailed results of feature selection are reported in a conference paper presented by the authors at the IEEE International Conference on Computing, Communications and Networking Technologies (ICCCNT) 2015 (Banerjee et al, ). Those results are omitted for brevity.…”
