Abstract
This paper presents the visual corpus interface created within the OPATCH project ('Open Platform for access to and Analysis of Textual documents of Cultural Heritage'). The interface combines a set of visualizations for textual data and language features with the aim to support linguistic analysis. The paper describes the choice of visualizations, their interlinking and their integration with a corpus search engine. It discusses challenges related to data handling and usage scenarios and lays out open needs for future work.
