Tolerating changes in a design psychology based web page wrapper

We introduce an innovative approach to wrapping semi-structured web pages in order to generate structured data. Unlike other work in this area that is based on physically specifying the location of information, our approach is based on human design psychology that captures more stable features in web pages, which we believe renders a more robust result in coping with changes in the web pages. In this paper, we focus on the product advertisement domain, and a set of design psychology principles for product advertisement is presented and used to design the wrapping rules. A case study in the mobile phone advertisement domain is used to evaluate this approach.
