Visualization, Search, and Error Analysis for Coreference Annotations

Markus Gärtner; Anders Björkelund; Gregor Thiele; Wolfgang Seeker; Jonas Kuhn

We present the ICARUS Coreference Explorer, an interactive tool to browse and search coreference-annotated data. It can display coreference annotations as a tree, as an entity grid, or in a standard textbased display mode, and lets the user switch freely between the different modes. The tool can compare two different annotations on the same document, allowing system developers to evaluate errors in automatic system predictions. It features a flexible search engine, which enables the user to graphically construct search queries over sets of documents annotated with coreference.

A Graphical Interface for Automatic Error Mining in Corpora

Gregor Thiele; Wolfgang Seeker; Markus Gärtner; Anders Björkelund; Jonas Kuhn

We present an error mining tool that is designed to help human annotators to find errors and inconsistencies in their annotation. The output of the underlying algorithm is accessible via a graphical user interface, which provides two aggregate views: a list of potential errors in context and a distribution over labels. The user can always directly access the actual sentence containing the potential error, thus enabling annotators to quickly judge whether the found candidate is indeed incorrectly labeled.

RePlay-DH - Realisierung einer Plattform und begleitender Dienste zum Forschungsdatenmanagement für die Fachcommunity - Digital Humanities

Uli Hahn; Sibylle Hermann; Petra Enderle; Florian Fritze; Markus Gärtner; Volodymyr Kushnarenko

Das Projekt RePlay-DH hat zum Ziel, ein Werkzeug zu entwickeln, das die Wissenschaftler bereits im Forschungsprozess bei der nachhaltigen Dokumentation und Archivierung der Forschungsdaten unterstutzt. Das zentrale Element dabei ist der „RePlay-Gedanke“: Wiederauffindbarkeit und Reproduktion von Forschungsergebnissen. Um praxisnahe Losungen zu schaffen, analysiert das Projekt hierfur exemplarisch Workflows aus der Computerlinguistik. Zwar kommen die Wissenschaftler in den digitalen Geisteswissenschaften oft sehr gut an die benotigten Werkzeuge und Eingabedaten, die Forschungsprozesse selbst werden jedoch haufig nur skizzenhaft dokumentiert. Mit RePlay-DH soll eine Moglichkeit geschaffen werden, den Arbeitsprozess der Forscher mit einem geringen Mehraufwand zu dokumentieren und fur Dritte nachvollziehbar zu machen. Dazu wird ein Java-Client entwickelt, der mit Hilfe von einfachen Versionierungswerkzeugen den Dokumentationsworkflow der Forschenden gezielt unterstutzt. In komplexen Projekten soll dieses Vorgehen dabei helfen, verschiedene Optionen wahrend des Forschungsprozesses auszuloten und zu dokumentieren. Dabei bleibt es stets den Wissenschaftlern uberlassen, welche Teile des eigenen Projekts archiviert, mit Kollegen geteilt oder veroffentlicht werden sollen.

Supporting Sustainable Process Documentation

Markus Gärtner; Uli Hahn; Sibylle Hermann

In this paper we introduce a software design to greatly simplify the elicitation and management of process metadata for researchers. Detailed documentation of a research process not only aids in achieving reproducibility, but also increases usefulness of the documented work for others as a cornerstone of good scientific practice. However, in reality, time pressure together with the lack of simple documentation methods makes documenting workflows an arduous and often neglected task. Our method for a clean process documentation combines benefits of version control with integration into existing institutional infrastructure and a novel schema for describing process metadata.

Multi-modal Visualization and Search for Text and Prosody Annotations

Markus Gärtner; Katrin Schweitzer; Kerstin Eckart; Jonas Kuhn

We present ICARUS for intonation, an interactive tool to browse and search automatically derived descriptions of fundamental frequency contours. It offers access to tonal features in combination with other annotation layers like part-ofspeech, syntax or coreference and visualizes them in a highly customizable graphical interface with various playback functions. The built-in search allows multilevel queries, the construction of which can be done graphically or textually, and includes the ability to search F0 contours based on various similarity measures.
