Brakuje metody opisu programów GIS, która pozwoliłaby poznać nie tylko ich funkcje i sposób komunikacji z użytkownikiem, ale również ich głęboką strukturę. Celem analizy semantycznej jest odkrycie tej struktury i zbadanie jej związku ze strukturą poznawczą dyscypliny macierzystej - geografii. Podstawową jednostką głębokiej struktury jest metafora.

GIS software descriptions are widespread but often useless, because they are unable to reveal the inner logic of the system. Like other complex software, GIS may be analysed in terms of three layers: 1) functionality, 2) user interface (shallow layer) and 3) cognitive structures (deep layer). Vendor information sources, factsheets and application studies cover, for the most part, functionality and shallow layer, neglecting deep structure. However, misunderstanding and mismatch between user cognitive structure and software structure severely impairs GIS usefulness, especially when big projects are concerned. The rescue may come from cognitive science and semiology rather than from software engineering. Semantic analysis should be used to 1) achieve good design for new systems, 2) describe exsisting software and make a foundation for professional critical activity, similar to literary or architectural one. Semantic analysis focuses on the mapping between domain-specific cognitive structure and corresponding deep software structure. The letter must be consistent (logically congruent), compact (devoid of unnecessary terms) and abstract (make use of general terms). Metaphors constitute basic components of deep software layer, conveying meaning and analogy from the real world or domain. To properly analyse system at hand, metaphors must be extracted first. The next step is to review each metaphor along five dimensions: 1) analogue (reference to external object), 2) properties, 3) behaviour, 4) composition (if consisting of simpler parts) and 5) relations to other metaphors within the system.
