INKE – CiteLens
CiteLens is a visualization tool for analyzing citation patterns in lengthy scholarly works like monographs or editions. Primarily, CiteLens is designed as an instrument for context analysis of citation. This type of citation analysis focuses on analyzing citations inside the citing text. The secondary purpose of the tool is as a reading aid to facilitate the understanding of and integration with text of complex critical apparati; for example, attempting to make monographs more user-friendly for undergraduate science students taking required humanities classes. This tool uses XML markup to highlight three levels of information: the relationship between citations and the citing text; the connection between citations included in the same footnote; and standard bibliographical information.
