PURPOSE: An advertising system based on context is provided to offer a higher advertisement considering the position of the advertisement viewer. CONSTITUTION: An interest object detection module(100) searches a user's preference by analyzing web document, and measuring a user's interest. A semantic abstraction module(200) performs semantic abstraction process in order to decide the reliability of the interest object. A public action detection module(300) detects a public reaction on the interest object. A use association information extraction module(400) extracts using relation information using a predetermined use relation pattern and object-action pairs. An advertisement search module(500) maps the public reaction about the interest object and the use relation information, and recommends an advertisement using the mapping result.

PURPOSE: A method for deciding a rank of trend is provided to decide the rank of trend by utilizing an attribute of the trend. CONSTITUTION: An appearance frequency of an object about the time is inputted(S202). Fluctuation of object trend is calculated from the difference between appearance frequency of the object at an end point and the appearance frequency of the object at a start point of a fixed time section(S204). The fluctuations of calculated object trends are compared. The rank of the trend is decided in the order of higher fluctuations. The information about the object is outputted according to the trend rank(S208).
