ViSCitR: Visual Summarization and Comparison of Hotel Reviews

Despite the availability of hotel booking platforms with customer reviews, selecting the best hotel or accommodation can still be difficult. This is partly because it is hard to directly contrast multiple shortlisted hotels. We propose a new visual interface, called ViSCitR, that goes beyond existing solutions in visually comparing ratings and personalizing the evaluation based on individual priorities. Targeted at a broad audience, it integrates several dimensions of comparison into a highly interactive document. The document contrasts the hotels visually and textually from different perspectives, including (i) a geographic perspective with points of interest, (ii) a comparison of ratings across different categories, (iii) rating changes over time, and (iv) summaries of the most noted positive and negative points from the review texts. The interface is accompanied by a sidebar for personalization, which supports selecting relevant points of interest and setting priorities. Changing these adapts the visual comparison across all interface sections to match the user’s preferences. A qualitative evaluation with potential hotel customers showed that the personalized visual comparison is valuable for all users, while the advanced features of the interface are leveraged to different extents.
