Corpora with high-quality linguistic annotations are an essential component in many NLP applications and a valuable resource for linguistic research. For obtaining these annotations, a large amount of manual effort is needed, making the creation of these resources time-consuming and costly. One attempt to speed up the annotation process is to use supervised machine-learning systems to automatically assign (possibly erroneous) labels to the data and ask human annotators to correct them where necessary. However, it is not clear to what extent these automatic pre-annotations are successful in reducing human annotation effort, and what impact they have on the quality of the resulting resource. In this article, we present the results of an experiment in which we assess the usefulness of partial semi-automatic annotation for frame labeling. We investigate the impact of automatic pre-annotation of differing quality on annotation time, consistency and accuracy. While we found no conclusive evidence that it can speed up human annotation, we found that automatic pre-annotation does increase its overall quality.

Der Beitrag untersucht im Rahmen von korpusgestütztem Belegmaterial die Bedingungen, unter denen Geräuschverben des Deutschen eine Direktivvariante aufweisen können. Dabei wird beabsichtigt, die wissenschaftliche Diskussion um Valenz- vs. Konstruktionsgrammatik mittels einer Analyse, die sich auf das Zusammenwirken von internen und externen lexikalischen Form- und Inhaltsrelationen stützt, zu bereichern.
Terminology practice in companies and its methods evolved over the course of the years. This process can be seen as a broadening of methods rather than a paradigm change. Although this development led to an improvement in the practice, many crucial problems still remain unsolved. In this article I point out the open questions in the current methodology and argue why they are essential for the success of terminology projects. Also, I present how these questions can be addressed by embedding the terminology in a broader discourse of language management and social psychology.
In order to explore the influence of context on the phonetic design of talk-in-interaction, we investigated the pitch characteristics of short turns (insertions) that are produced by one speaker between turns from another speaker. We investigated the hypothesis that the speaker of the insertion designs her turn as a pitch match to the prior turn in order to align with the previous speaker’s agenda, whereas non-matching displays that the speaker of the insertion is non-aligning, for example to initiate a new action. Data were taken from the AMI meeting corpus, focusing on the spontaneous talk of first-language English participants. Using sequential analysis, 177 insertions were classified as either aligning or non-aligning in accordance with definitions of these terms in the Conversation Analysis literature. The degree of similarity between the pitch contour of the insertion and that of the prior speaker’s turn was measured, using a new technique that integrates normalized F0 and intensity information. The results showed that aligning insertions were significantly more similar to the immediately preceding turn, in terms of pitch contour, than were non-aligning insertions. This supports the view that choice of pitch contour is managed locally, rather than by reference to an intonational lexicon.
Der Beitrag stellt die Ergebnisse einer Onlinebenutzungsstudie zur Funktion und Rezeption von Belegen im einsprachigen deutschen Onlinewörterbuch elexiko vor. Diese werden vor dem Hintergrund allgemeiner metalexikographischer und konzeptioneller Überlegungen interpretiert, ein Ausblick führt zu weiteren relevanten Fragestellungen.
