Evald 3.0


EVALD 3.0 software serves for automatic evaluation of surface coherence (cohesion) in Czech texts written by native speakers of Czech (click here for EVALD 3.0 for Foreigners that is designed for non-native speakers of Czech). For more information, visit the project web pages.

The software is created for assessing the surface coherence of authentic writing samples (essays) written by native speakers of Czech. In other words, it is trained to evaluate prosaic texts whose content and form correspond to the common school essays created as a comprehensive piece of writing on a given topic, e.g. during the lessons of Czech at secondary schools, at the highest grades of elementary schools or during the graduation exam of Czech. When evaluating a different type of text (poems, journalistic texts etc.), the software may not work reliably. The minimum length of the inserted text is 300 words – shorter texts do not provide enough linguistic material on which the real level of the text can be observed.
The evaluated texts can be used for scientific purposes, freely distributed and published.
