In science:

We further propose a theoretical component to the framework based on signaling theory from economics (see Section 6) and use it to reason about the factors that influence deception prevalence in online review communities.
Estimating the Prevalence of Deception in Online Review Communities
We find first that the prevalence of deception indeed varies by community.
Estimating the Prevalence of Deception in Online Review Communities
However, because it is not possible to validate these estimates empirically (i.e., the gold-standard rate of deception in each community is unknown), we focus our discussion instead on the relative differences in the rate of deception between communities.
Estimating the Prevalence of Deception in Online Review Communities
Here, the results confirm our hypotheses and suggest that deception is most prevalent in communities with a low signal cost.
Estimating the Prevalence of Deception in Online Review Communities
Importantly, when measures are taken to increase a community’s signal cost, we find dramatic reductions in our estimates of the rate of deception in that community.
Estimating the Prevalence of Deception in Online Review Communities
The resulting sampling equations, and the corresponding Bayesian Prevalence Model estimate of the prevalence of deception, πbayes , are given in greater detail in Appendix A.

DECEPTION DETECTION 4.1 Deception Classifier The next component of the framework given in Section 2 is the deception classifier, which predicts whether each unlabeled review is truthful (real) or deceptive (fake).
Estimating the Prevalence of Deception in Online Review Communities
Following previous work , we assume given some amount of labeled training reviews, so that we can train deception classifiers using a supervised learning algorithm.
Estimating the Prevalence of Deception in Online Review Communities
Previous work has shown that Support Vector Machines (SVM) trained on n-gram features perform well in deception detection tasks [8, 13, 15].
Estimating the Prevalence of Deception in Online Review Communities
Furthermore, the simple approach just outlined has been previously evaluated to be nearly 90% accurate at detecting deception in a balanced dataset .
Estimating the Prevalence of Deception in Online Review Communities
Classifier Sensitivity and Specificity Both Prevalence Models introduced in Section 3 can utilize knowledge of the underlying deception classifier’s sensitivity (η∗ ), i.e., deceptive recall rate, and specificity (θ∗ ), i.e., truthful recall rate.

Following Ott et al. , we excluded all reviews with fewer than 150 characters, as well as all non-English reviews.6 5.1 Training Reviews (Dtrain ) Training a supervised deception classifier requires labeled training data.

Deceptive Reviews : In Section 1, we discuss some of the difficulties associated with obtaining gold-standard labels of deception, including the inaccuracy of human judgements, and the problems with self-reports of deception.

To date, this is the only publicly-available7 gold-standard deceptive opinion spam dataset.
