Evald 1.0


EVALD 1.0 software serves for automatic evaluation of surface coherence (cohesion) in Czech texts written by native speakers of Czech (click here for EVALD 1.0 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 (e.g. length) 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 or at the highest grades of elementary schools or during the graduation exam of Czech etc. When evaluating a different type of text (e.g. too short texts, poems etc.), the software may not work reliably.
