Abstract
The paper presents an advanced, highly customizable corpus query interface KonText built on top of core libraries of the open-source corpus search engine NoSketch Engine (NoSkE). KonText overcomes some limitations of the original NoSkE user interface and provides integration capabilities allowing connection of the basic search service with other language resources (LRs).
The introduced features are based on long-term feedback given by the users and researchers of the Czech National Corpus (CNC) along with other LRs providers running KonText as a part of their services. KonText is a fully operational and mature software deployed at the CNC since 2014 that currently handles thousands user queries per day.
