Short Samples:
Institutiones (Iustinianus 482-565 dC)
(Last update: May 3th, 2003. The version of T-LAB used was 3.0)

T-LAB functions used in this short example are those highlighted in red in the image on the right.

It is well known that the emperor Justinian devoted a lot of his time to reorganizing Roman law.

The Institutiones, particularly, marks a "high point" in his work.

In a first exploration of its content we have used one of T-LAB's functions: Co-Word Mapping.

This type of map shows the key words arranged systematically within a two-dimensional area.

Each key word represents a small group of "associated" words, that is a small cluster of words co-occurring in the elementary contexts of the corpus (the sentences of the text).

The two-dimensional area is organized along two axes (X-horizontal, Y-vertical) which, just as with topographical maps, represent the "compass points" (north-south, east-west) and therefore help to orientate the interpretation.

In statistical terms, the two axes are factors.

In order to verify the coherence of the data, with a simple click on the graph labels, we explored the composition of the following four clusters.

HERES
TESTAMENTUM
TUTOR
USUFRUCTUS

 

 

 

 

Subsequently, in order to make a closer examination, we used another T-LAB tool: the Correspondence Analysis.

 

In the graph, every point indicates the "position" of one of the four books into which the Institutiones are subdivided.

As can be seen, on the horizontal axis (East-West) the contents of the QUARTus book (the fourth) contrast with those of the remaining three.


In order to understand what this difference consists of, we can use the tables that T-LAB provides automatically.

The table on the left shows "the characteristic" words of the west polarity of the graph (that of the liber quartus); correspondingly, the table on the right shows the characteristics of the east polarity.

As can be seen, the key words that organize the west polarity seem more properly to concern so-called criminal law ("furtum", "condemnare" " poena"), while those on the east polarity mainly seem to involve testamentary rights ("tutor ", " testamentum ", " heres").

Using the Associations function, we can precisely examine the "local meaning" of some key words in the text examined.
Every word analyzed (in this case, POENA and TESTAMENTUM) is placed in the center and all the others are distributed around it, each at a distance proportional to its degree of association.
In other words, the meaningful relationships are only those between the central word and each of the others.
In both cases, its proximity to the center indicates the "association" relationship of each word (or lemma) with the two selected key words.
