A false-advertisement judgement system aims at recognizing and explaining the illegal false advertisements. In this paper, we incorporate the convolutional neural network (CNN) with word embeddings and syntactic features in the system. The recognition experiments show that Dependency-based CNN (DCNN) achieves F-scores of 86.77%, 93.18%, and 87.46% in the cosmetics, food, and drug datasets, respectively. Moreover, the explanation of illegality experiments shows the F-scores of 56.19%, 50.36%, and 62.06% in the three datasets. Our judgement system can contribute to different roles in the online advertising. ? 2017 International World Wide Web Conference Committee (IW3C2), published under Creative Commons CC BY 4.0 License.Convolutional neural networkOpinion spam detectionOverstated advertisement identification[SDGs]SDG16conference paper10.1145/3041021.30542332-s2.0-85056527339https://www.scopus.com/inward/record.uri?eid=2-s2.0-85056527339&doi=10.1145%2f3041021.3054233&partnerID=40&md5=7827d2a0969b54b0ac86e7f3c012ccf9
