The MVED in action

Displaying the variants In a tree In columns

Provides overview Depicts several editions at once Depicts variants along their offset in the text

Provides more detail

Provides more detail Depicts patterns in context

Different abstractions Variants grouped by the text they appear on Variants grouped by the length in characters

Discovering patterns The string “que” across the base text The abbreviation across the editions

Analyzing copies of the same edition Identifying false variants

Why ItLv? Analyze similarities and differences among texts Validate the results of a textual collation Discover different “issues” of an edition Discover authorship Discover patterns Perform literary analyses New discoveries using different units (e.g. chapters, signatures)

Conclusions and Future Work Provides a flexible interface to visualize differences among several texts Provides context and detail for the variants Different visualizations of the same data set provide different abstractions More issues with more chapters Different users different needs
