First, a user profile represented as a user＇ s topics of interest vector is created by analyzing the user＇ s click through data based on PLSA, then the user＇ s queries are mapped into categories based on the user＇ s preferences, and finally the result list is re-ranked according to the user＇ s interests based on the new proposed method named user-oriented PageRank （UOPR）. Experiments on real life datasets show that the user-oriented search system that adopts PLSA takes considerable consideration of user preferences and better satisfies a user＇ s personalized information needs.展开更多

The analysis from the inside and the honest reflection of the interplay between poetry, music, and contemporary popular culture might lead to a better understanding of the poetry made at the end of the 20th century--beginning of the 21 st century. The corpus analyzed is a series of poems written between 1994 and the present day, under the generic title of ditty, published in several books （between which a bilingual pamphlet, Ditties/Cfntecelce）, 1998）, and the paper speaks about their genesis, their poetics, and hopes to help the process of their interpretation, as well as to bring a new interpretation of the poetry/music relationship展开更多
