T-LAB has been designed for Windows platforms (98, 2000, NT, XP, Vista, Windows Seven).

During the pre-processing phase, T-LAB carries out the following treatments: corpus normalization, multi-word and stop-word detection, segmentation into elementary contexts (i.e. sentences or paragraphs), automatic lemmatization (*), key-terms selection.

(*) Currently the automatic lemmatization is available for the following languages: English, French, Italian, Spanish and Portuguese; moreover, without automatic lemmatization, T-LAB allows us to analyse texts in all languages supporting ASCII/ANSI format.

Subsequently T-LAB allows the integrated use of three kinds of tools for text analysis:

CO-OCCURRENCE ANALYSIS

Word Associations (Manual - Video )
Comparison between Word pairs (Manual - Video )
Co-Word Analysis and Concept Mapping (Manual - Video )
Sequence Analysis (Manual - Video )
Concordances (Manual - Video )

THEMATIC ANALYSIS

Modeling of Emerging Thems (Manual - Video )
Thematic Analysis of Elementary Contexts (Manual - Video )
Sequences of Themes (Manual - Video )
Key Contexts of Thematic Words (Manual - Video )
Thematic Document Classification (Manual - Video )

COMPARATIVE ANALYSIS

Specificity Analysis (Manual - Video )
Correspondence Analysis (Manual - Video )
Multiple Correspondence Analysis (Manual - Video )
Cluster Analysis (Manual - Video )

 

All the T-LAB functions allow charts and tables to be saved. Texts and documents may be analyzed and compared through the use of definite variable by user. Currently, the number of available categorical variables is fixed at 50, each allowing subdivision of the corpus into as many as 150 subsets which can be compared. T-LAB has been tested with a corpus of 30 Mb, equal to about 18,000 pages in ASCII format.

The on-line-help is contextual and hypertextual.
