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).
Other Details
When you view your results table, hold your cursor over any of
the manuscript sigla to view the full manuscript name.
Click on any CantusIDNumber to bounce to the CANTUS search
results for
that chant.
The "cursus" field indicates "M" for "monastic" or "S" for
"secular" (also known as Roman or cathedral).
You can type in your own series of responsories if a source
against
which you wish to compare is not entered in this database.
Retrieve
CantusIDNumbers from the download file '"Master
Table" of Texts and CantusIDNumbers' (.xls or .mdb formats),
available
on the CANTUS home page.
(If all of the responsories in the series to be entered manually are
included in CAO, you can create your own CantusIDNumbers by placing two
zeros in front of the four-digit CAO number. I.e., CAO "6157"
becomes CantusIDNumber "006157".)

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.
