First Claim
1. One or more computer-readable media storing computer-executable instructions that, when executed on one or more processors, perform acts comprising:
- identifying one or more photographs from a plurality of online journals;
clustering the one or more photographs into one or more views from which the one or more photographs have been captured;
modeling author, context and content information associated with the one or more views to discover one or more representative photographs and build author correlations;
filtering the author correlations and the one or more representative photographs; and
providing personalized recommendations to a user based at least in part on the filtering of the author correlations and the one or more representative photographs.

Abstract
A blog-based city landmark discovery framework is described to discover and summarize popular scenes and their representative views from blog photos to provide online personalized tourist suggestions. First, a location extraction algorithm is implemented to infer geographical associations of blog photos from their contextual descriptors, thus providing the ability to harvest city scene photos from web blogs. Second, a visual-textual hierarchical clustering scheme is adopted to organize crawled photos into a scene-view structure, and present a PhotoRank algorithm to discover representative views within each scene by viewing the representative photo selection problem as a popularity ranking problem in a visual correlation environment. Third, author, context and content issues are evaluated in a unified Landmark-HITS model to discover representative scenes as well as build author correlations. The author correlations further facilitate a collaborative filtering process for online personalized tourist suggestions based on an author'"'"'s previous travel logs.
