We describe the outcome of the 2023 edition of the CheckThat!Lab at CLEF. We focus on subjectivity (Task 2), which has been proposed for the first time. It aims at fostering the technology for the identification of subjective text fragments in news articles. For that, we produced corpora consisting of 9,530 manually-annotated sentences, covering six languages - Arabic, Dutch, English, German, Italian, and Turkish. Task 2 attracted 12 teams, which submitted a total of 40 final runs covering all languages. The most successful approaches addressed the task using state-of-the-art multilingual transformer models, which were fine-tuned on language-specific data. Teams also experimented with a rich set of other neural architectures, including foundation models, zero-shot classifiers, and standard transformers, mainly coupled with data augmentation and multilingual training strategies to address class imbalance. We publicly release all the datasets and evaluation scripts, with the purpose of promoting further research on this topic.
Das Fach Informationswissenschaft ist aktueller denn je. Die Absolventinnen und Absolventen werden in der Industrie nachgefragt, es gibt praktisch keine Arbeitslosigkeit. Auch die Nachfrage bei den Studienanfängern ist stabil auf hohem Niveau. Andererseits ist das Fach einem starken Wandel unterzogen. Die Inhalte werden technischer, internationaler und forschender. Den Wandel tragen die neue Generation der Studierenden und die Professorinnen und Professoren. Um diese Änderungen deutlich zu machen, haben wir den Studiengang in Darmstadt in „Information Science“ umbenannt.
