QuitaUp

The QuitaUp application was created in order to provide linguists and a wider range of users with a simple tool for calculating selected stylometric indicators that quantitatively express some properties of the text. This includes, for example, the calculation of vocabulary richness, thematic concentration or text activity.

The app is available online at: https://www.korpus.cz/quitaup/

The app is accompanied with detailed manual describing all implemented stylometric indices.

Uploaded texts must be in .txt, .docx, .doc, .odt, .rtf or .pdf format with Unicode encoding (UTF-8).

QuitaUp offers basic text-processing functions (tokenization, lemmatization, POS tagging, syntactic parsing). These functions are available for different languages (see the Language tab). This text processing is based on the UDPipe models (more on http://ufal.mff.cuni.cz/udpipe).

Implemented indices:

• Tokens
• Types
• TTR
• h-point
• Hapaxes
• Hapax legomena percentage
• Entropy
• Verb distance
• Activity
• Descriptivity
• Average Token length
• Thematic concentration
• Secondary thematic concentration
• Moving Average Type-Token Ratio (MATTR, for window size L=100)
• Moving Average Type-Token Ratio (MATTR, for window size L=500)
• zTTR: Normalized TTR
• Moving Average Morphological Richnes (MAMR, for window size L=100)
• Moving Average Morphological Richnes (MAMR, for window size L=500)
