Coral: Corpus access in controlled language


Kuhn, Tobias; Höfler, Stefan (2012). Coral: Corpus access in controlled language. Corpora, 7(2):187-206.

Abstract

This paper presents Coral, an interface in which complex corpus queries can be expressed in a controlled subset of natural English. With the help of a predictive editor, users can compose queries and submit them to the Coral system, which then automatically translates them into formal AQL statements. The paper gives an overview of the controlled natural language developed for Coral and describes the functionalities of the predictive editor provided for it. It also reports on a user experiment in which the system was evaluated. The results show that, with Coral, corpora of annotated texts can be queried easier and faster than with the existing ANNIS interface. Our system demonstrates that complex corpora can be accessed without the need to learn a complicated formal query language.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
