SEMANA is a software written in Transcript®, the programming language of Revolution Studio®. It is aimed at facilitating the interoperability of procedures useful for Semantic Analysis and, more generally, for Knowledge Discovery in Data Bases.
Compiled versions may be used on MacOS X, Windows and Linux.
The software is
presently available for Apple
MacOS X and for MS
Windows XP and Vista.
SEMANA includes:
- Data and Meta-data
Editing and Preprocessing
assistance to attribute and values edition, tree-structure
visualization, transformation of multi-valued tables into one-valued
tables, nominal and logical scaling procedures, discretization of
quantitative variables, clarification of objects and attributes,
co-occurrence tables (Burt's tables), etc.
- Rough Set Theory
(according to Pawlak's procedures)
lower and upper approximations, reducts, core, discrimination power.
- Decision Logic
determination of minimal rules (for given subsets of conditional and
decisional subsets of attributes), detection of inconsistencies.
- Formal Concept Analysis
(application of Wille and Ganter procedures)
graphical representation of lattices, alpha-Galois lattices.
- Statistical analyses
including Correspondence Factor Analysis and Bottom-Up Hierarchical
Classification (according to Benzecri programs) and classical
statistics such as correlation matrices, similarity indices, feature
matching, cluster coefficient, etc.
