-The KWords application is used for the analysis of texts based on their comparison with the general usage ([[en:pojmy:referencni|reference]] corpus). Its aim is to identify so-called [[en:pojmy:keyword|keywords]], which are [[en:pojmy:word|word forms]] appearing in the inspected text with a significantly higher frequency than in the reference corpus which should reflect the common usage. These key words serve as a basis for textual analysis and interpretation.+The KWords application is used for the analysis of texts based on their comparison with the general usage ([[en:pojmy:referencni|reference]] corpus).

 The identification of [[en:pojmy:keyword|keywords]] takes place based on a comparison of each word's relative [[en:pojmy:frekvence|frequency]] in the given text with the same word's relative frequency in the reference corpus. Several tests are used to determine the statistical significance of the differences, two of which are implemented in KWords: [[en:pojmy:chi2|chi2]] and [[en:pojmy:loglikelihood|log-likelihood]]. Keywords in the analyzed text are marked <fc #ff0000>red</fc>.  The identification of [[en:pojmy:keyword|keywords]] takes place based on a comparison of each word's relative [[en:pojmy:frekvence|frequency]] in the given text with the same word's relative frequency in the reference corpus.

-The results of the keyword analysis are always influenced by the choice of reference corpus, which should be seen as a neutral language background with which we compare the analyzed text. For example, when analyzing the New Year speeches of the last Communist president G. Husák, we notice that compared to current usage there is a high frequency of words such as  //socialistický// (socialistic), //soudružky// (comrades) etc., but this i not the case when compared to a reference corpus from the same period. Currently, the following reference corpora can be used in the KWords application: +The results of the keyword analysis are always influenced by the choice of reference corpus, which should be seen as a neutral language background with which we compare the analyzed text.
