Ranking Method using Comparative Relations extracted from CGM

A comparative sentence expresses a relation between two objects. By mining the information from a large number of documents generated by consumers, we can rate the values of objects eciently. This paper proposes a method of mining the comparative relations and ranking the objects based on mined results. We generate the graph, each node corresponds to a object, and each edge expresses the relation between two objects. By applying the PageRank method to the graph, the system brings order to the object. This type of graph can be thought of as modeling the behavior of a potential customer.
