Integrated search service system and method

A system and a method for providing an integrated search service are provided to classify search results into a plurality of groups, which are expressed by an image, based on contents, and adjust the size of each image according to more than one property such as importance or popularity of the group among the groups provided as the search result. A clustering engine(120) groups resources stored in a database into a plurality of clusters respectively including the resources related to a common topic. An image extracting engine(124) selects a representative image of respective clusters. A web server(140) provides an array of the representative image of the clusters. The size of the representative images is adjusted according to more than one property of the clusters. The characteristic includes the number of resources. The size of the representative image is proportion to the number of resources. The representative images are selected from the images related to image resource locators included in the resources and titles related to the resources. A category search system determines a category of the resources stored in a database. A sensory search system extracts a sensory word from the resources stored in the database.
