A general principle for all user interface design is to go through all of your design elements and remove them one at a time. If the design works as well without a certain design element, kill it.

Yu, Bei (2011): The emotional world of health online communities. In: Proceedings of the 2011 iConference 2011. pp. 806-807.

This article presents a preliminary study on the emotional world of health online communities. Using sentiment analysis and natural language processing techniques, this study aims to (1) examine the strength of various kinds of emotions (positivity, optimism, negativity, anxiety, anger, and sadness) in online health forum discussions, and (2) compare the emotional status and expression of forum participants under different roles, such as askers and answerers, men and women, and caregivers and patients. This study is expected to improve the understanding of the emotional communication in online health communities.

Li, Guoliang, Feng, Jianhua, Wang, Jianyong, Yu, Bei and He, Yukai (2008): Race: finding and ranking compact connected trees for keyword proximity search over xml documents. In: Proceedings of the 2008 International Conference on the World Wide Web 2008. pp. 1045-1046.

In this paper, we study the problem of keyword proximity search over XML documents and leverage the efficiency and effectiveness. We take the disjunctive semantics among input keywords into consideration and identify meaningful compact connected trees as the answers of keyword proximity queries. We introduce the notions of Compact Lowest Common Ancestor (CLCA) and Maximal CLCA (MCLCA) and propose Compact Connected Trees (CCTrees) and Maximal CCTrees (MCCTrees) to efficiently and effectively answer keyword queries. We propose a novel ranking mechanism, RACE, to Rank compAct Connected trEes, by taking into consideration both the structural similarity and the textual similarity. Our extensive experimental study shows that our method achieves both high search efficiency and effectiveness, and outperforms existing approaches significantly.

Plaisant, Catherine, Rose, James, Yu, Bei, Auvil, Loretta, Kirschenbaum, Matthew G., Smith, Martha Nell, Clement, Tanya and Lord, Greg (2006): Exploring erotics in Emily Dickinson's correspondence with text mining and visual interfaces. In: JCDL06: Proceedings of the 6th ACM/IEEE-CS Joint Conference on Digital Libraries 2006. pp. 141-150.

This paper describes a system to support humanities scholars in their interpretation of literary work. It presents a user interface and web architecture that integrates text mining, a graphical user interface and visualization, while attempting to remain easy to use by non specialists. Users can interactively read and rate documents found in a digital libraries collection, prepare training sets, review results of classification algorithms and explore possible indicators and explanations. Initial evaluation steps suggest that there is a rationale for "provocational" text mining in literary interpretation.
