Dictionary building
The option Dictionary building opens a window in which the user can carry out some operations on the corpus dictionary.
The user
can rename or group the avalaible lemmas; furthermore he can export the dictionary
or import a customized dictionary (also supplied
by a third part).

The starting point is a table (the Corpus Dictionary) that reports the following information:
- word/lemma
correspondences;
- word occurrences;
- some labels which refer to the automatic lemmatization
(see the "INF" column).
Before any operation, by selecting (double click) specific words and using the Contexts button, it is possible to check their concordances (see below).

The possible
operations, even though different in their goals (revision of the lemmatizations
and/or applications of grids for content analysis), all give a reorganization
of the T-LAB
database, thus creating different tables used to analyse data. Therefore all
operations must be done for the words (lemmas or categories) considered to be
interesting for the subsequent analyses. T-LAB,
in fact, makes a further option available, Customized
Settings, with which users can decide which lemmas to "keep" and which to
"discard".
The two functions (Dictionary Building and
Customized Settings) are strongly interconnected and the
user can easily move from one to the other, also in order to change one's choices.
In Dictionary building there are two operating modalities:
- "one-by-one", with direct changes (selecting and typing) in the column "Lemma";
- "by groups", with the possibility of moving selected words (double click) to the box on the right and, afterwards, re-denominating them by using the option "replace".
In the second case, the new label can be chosen from the selected lemmas (just click on an item in the box on the right) or by typing a new label in the appropriate box.
In order
to import
a customized dictionary, your file - Dictio.diz
or Dictionary.diz - must be located in the folder
of the corpus in analysis.
It can be made up of "n" lines, each with a couple of strings separated
by the character ";".
The maximum length of a string (word, lemma or category) is 50 characters: neither
blank spaces no apostrophes must be included.
For each couple, the first string - on the left - indicates the label (lemma
or category) defined by the user, the second indicates the corresponding word
(Dictio.diz case)
or lemma (Dictionary.diz case) already present
in T-LAB
dictionary.
These are some examples:
| (File Dictio.diz) | (File Dictionary.diz) |
|
ACCEPT;accept ------ |
BIOTECH;biotech --- |
According to the type of
file you import, the changes will be as follows:
![]() |
![]() |
N.B.:
- The button with the the floppy disk icon allows us to
save a file (Dictio.diz),
ready-made to be reused as a T-LAB
dictionary, even after it has been modified and set up by the user;
- Using the option Save your settings (see Customized
Settings) the same corpus - without need of further importation - can be
analysed with several dictionaries (up to a maximum of 10);
- Using the
option Lemmatized Corpus it is possible to export
a copy of the corpus ( .txt file) in which every word will be replaced by the
corresponding lemma or category.
-
W hen the dictionary has been modified, the following analyses on the same corpus
are available only as customized settings.
