KoralQuery - a General Corpus Query Protocol
Joachim Bingel, Nils Diewald · Publication Server of the Institute for German Language (Institute for German Language) · 2015
The task-oriented and format-driven development of corpus query systems has led to the creation of numerous corpus query languages (QLs) that vary strongly in expressiveness and syntax. This is a severe impediment for the interoperability of corpus analysis systems, which lack a common protocol. In this paper, we present KoralQuery, a JSON-LD based general corpus query protocol, aiming to be independent of particular QLs, tasks and corpus formats. In addition to describing the system of types and operations that KoralQuery is built on, we exemplify the representation of corpus queries in the serialized format and illustrate use cases in the KorAP project.
