Description	Metoda Latent Semantic Indexing byla aplikována pro vyhledávání podobných vzorků v databázi vod. Pět dotazů bylo vybráno tak, aby respektovalo rozdílné lokality. (cs) The latent semantic indexing (LSI) method was applied for the retrieval of similar samples (those samples with a similar composition) in a dataset of groundwater samples. The LSI procedure was based on two steps: (i) reduction of the data dimensionality by principal component analysis (PCA) and (ii) calculation of a similarity between selected samples (queries) and other samples. The similarity measures were expressed as the cosine similarity, the Euclidean and Manhattan distances. Five queries were chosen so as to represent different sampling localities.
