TOWARDS AN INDEX OF IDIOLECTAL SIMILITUDE 509
which is very relevant in real forensic cases concerned with
linguistic profiling.
Hypothesis 1 is also confirmed by all 3 methods for the
morphosyntactic modules (Figure 3) and the discourse-pragmatic
modules (Figure 4). In both modules in the three languages, all
interspeaker/writer IIS values are relatively low in general (they
range between 0.6 and 0.8), which is an expected result
considering that all the subjects belong to the same dialectal
area.
