Responsory Series: Advent and Lent

This analysis tool allows you to compare series of responsories in several ways.

Instructions and Method
You can select any one of the entered series of responsoria prolixa for Matins for the four Sundays of Advent or the six Sundays of Lent and use it as the basis (the "head") for a comparison with the other records entered for that particular Sunday. There are three methods of comparison available, and the results are listed with the closest affiliations at the top.

Follow the instructions at the top of the screen to select the Sunday series (A1=first Sunday in Advent, A2=second Sunday in Advent, L1=first Sunday in Lent, L2=second Sunday in Lent, and so on) and the manuscript.
Click on "List of MS's" (to the right of the "Set Series and MS" button) to obtain a list of the available manuscripts and their sigla (many of which are modelled after LeRoux).
If there are no responsory CantusIDNumbers (CAO1, CAO2, etc.) when you click "Set Series and MS," then that material is either not included in that manuscript or is not yet entered into this database. Contact CANTUS if you desire clarification.

The default "compare method" is "Edit Distance."
"Edit Distance" is the minimum number of insertions, deletions, or substitutions needed to turn one string into another. For example, the Edit Distance between "test" and "tent" is 1. The Edit Distance between "test" and "tst" is also 1. In this Responsory Series Database, records returned with an Edit Distance of zero are exact matches, and those with higher figures are presumably less-closely affiliated.

Another comparison option is "LCS" = Longest Common Sequence.
For example, for the two strings "abcdefg" and "a23cd4e567" the LCS is "acde." The items do not need to be contiguous in order to provide results. For the purposes of this Responsory Series Database, this method may prove useful when working with fragmented or partly-illegible sources.

The third option for comparative method is "Matches/Pairs."
This method searches for 1) chants which are common to each series (i.e., the number of "matches"), and 2) pairings of chants within the ordering of these responsory series (i.e., start-A-B-C-D-fine in one source compared to start-B-A-C-D-fine in another source would result in 4 matches and 2 pairs).

This Responsory Series tool was developed by Debra Lacoste within the scope of a Post-Doctoral Fellowship funded by the Social Sciences and Humanities Research Council of Canada, with additional support from the ITS department of the University of Western Ontario. Dr. Lacoste would like to acknowledge the splendid "webification" of this material by Gerard Stafleu (UWO), based on her algorithm. She is also indebted to Robert Klugseder (Universität Regensburg) for facilitating a mutual exchange of data, thus minimizing data-entry and providing proofread tables for René-Jean Hesbert's Advent responsory series.
