text or corpus. Another collection of schemas of so-called textualindexing serves for
drafting a textual annotation (see Figure 14.15).
A very significant collection in this library of schemas of indexing covers all
those schemasofindexing which incorporate predefined terms or lists of terms, from
which the analyst has to make a choice (in contrast to the schemas of verbal
indexing discussed above which allow the analyst to freely produce an appropriate
indexing). These schemas belong to the collection Schemas of indexing using the
ASWthesaurus (Figure 14.14).

As Figure 14.16 shows, the collection entitled Schemas of indexing using the
ASW thesaurus is highly diverse, and made up of a great many thematically-
specialized schemas of indexing. Indeed, as we can see in Figure 14.16, there is one
characteristic shared by all the schemas making up this collection, which is that they
“point” to a range of predefinedvalues in the ASW thesaurus. A range of predefined
values is a semantic space which we call a facet and which corresponds to what
Greimas termed a classeme , i.e. a semantic trait which (as the appellation suggests)
classes together a certain number of values (standardized expressions, descriptors)
in the thesaurus.
