They are organized in groups to post with specific purposes and sometimes even confuse or mislead normal users.In this paper,we study the individual and group characteristics of organized posters. A classifier is constructed based on the individual and group characteristics to detect them. Extensive experimental results on three real datasets demonstrate that our method based on individual and group characteristics using SVM model(IGCSVM) is effective in detecting organized posters and better than existing methods. We take a first look at finding the promoters based on the detected organized posters of our IGCSVM method. Our experiments show that it is effective in detecting promoters.展开更多

Nowadays, posters are full of various types of semiotic modes with their wide applications of multimodality. This phenomenon is reflected in real estate posters as well, therefore, this thesis hopes to explore their essence of using multimodality and discussing meaning construction of the real estate posters.展开更多
