Watrous-deVersterre, Lori, Wang, Chong and Song, Min (2012): Concept chaining utilizing meronyms in text characterization. In: JCDL12 Proceedings of the 2012 Joint International Conference on Digital Libraries 2012. pp. 241-248. http://dx.doi.org/10.1145/2232817.2232862

For most, the web is the first source to answer a question formulated by curiosity, need, or research reasons. This phenomenon is due to the internet's ubiquitous access, ease of use, and the extensive and ever expanding content. The problem is no longer the need to acquire content to encourage use, but to provide organizational tools to support content categorization that will facilitate improved access methods. This paper presents the results of a new text characterization algorithm that combines semantic and linguistic techniques utilizing domain-based ontology background knowledge. It explores the combination of meronym, synonym, and hypernym linguistic relationships to create a set of concept chains used to represent concepts found in a document. The experiments show improved accuracy over bag-of-words based term weighting methods and reveal characteristics of the meronym contribution to document representation.

Baudisch, Patrick, Xie, Xing, Wang, Chong and Ma, Wei-Ying (2004): Collapse-to-zoom: viewing web pages on small screen devices by interactively removing irrelevant content. In: Proceedings of the 2004 ACM Symposium on User Interface Software and Technology 2004. pp. 91-94. http://doi.acm.org/10.1145/1029632.1029647

Overview visualizations for small-screen web browsers were designed to provide users with visual context and to allow them to rapidly zoom in on tiles of relevant content. Given that content in the overview is reduced, however, users are often unable to tell which tiles hold the relevant material, which can force them to adopt a time-consuming hunt-and-peck strategy. Collapse-to-zoom addresses this issue by offering an alternative exploration strategy. In addition to allowing users to zoom into relevant areas, collapse-to-zoom allows users to collapse areas deemed irrelevant, such as columns containing menus, archive material, or advertising. Collapsing content causes all remaining content to expand in size causing it to reveal more detail, which increases the user\'s chance of identifying relevant content. Collapse-to-zoom navigation is based on a hybrid between a marquee selection tool and a marking menu, called marquee menu. It offers four commands for collapsing content areas at different granularities and to switch to a full-size reading view of what is left of the page.
