CATview is an interactive visualization tool offering effective functionalities for navigating and exploring the textual differences of the variants of a manuscript.
CATview processes data generated by collation tools such as LERA, CollateX or Juxta.
It is meant to be embedded in websites as a powerful add-on for digital editions and web-based frameworks for the editing process.
CATview offers multiple, easily usable functionalities for exploratory analysis of the genesis of a manuscript, in particular:
CATview represents text segments (which can be lines, sentences, or paragraphs) as rectangles in a tabular manner whereat (in horizontal mode) a row corresponds to a text witness and a column to aligned segments of the different text witnesses, i.e., segments that are related to each other.
CATview has a built-in zoom that is activated by scrolling with the mouse wheel
CATview illustrates the degree of dissimilarity between aligned segments by the rectangles' color.
The darker the color of a segment the more different the segment is with respect to the other aligned segments.
CATview links the rectangles of the overview bar to the respective text segment.
The current scroll position in the text is marked by a scroll spy in the overview bar.
CATview visualizes search hits by coloring (yellow) the segments matching the search request.
CATview offers a comfortable selection of consecutive text segments by drawing a box around them.
CATview allows statistical analysis with respect to text excerpts.
CollateX is a software to (a.) read multiple versions of a text, (b.) identify differences by aligning tokens, and (c.) output the alignment results for further processing, for instance (d.) to support the production of a critical apparatus or the stemmatical analysis of a text's genesis.
