  abstract  = {The advent of Transformer-based Large Language Models (LLMs) has
               led to an unprecedented surge of AI-generated text (AIGT) across
               online platforms and academic domains. While these models exhibit
               near-human fluency and stylistic coherence, their widespread adoption
               has raised concerns about authorship integrity, research quality,
               and the recursive contamination of training corpora with synthetic
               data. These developments underscore the need for reliable AIGT
               detection methods and benchmark datasets, particularly for malicious
               or deceptive ghostwriting scenarios where AIGT is intentionally
               crafted to evade detection. To address this, we present GhostWriter,
               a large-scale, bilingual (German and English), multi-generator,
               and multi-domain dataset for AIGT detection. The dataset comprises
               human- and AI-authored texts produced under domain-specific ghostwriting
               conditions, including examples intentionally embedded within otherwise
               human-written texts to obscure their AI origin. With GhostWriter,
               we (i) aim to expand the resources available for German AIGT datasets,
               (ii) emphasize mixed or fused synthesizations---since most existing
               corpora are limited to the document level---and (iii) introduce
               specifically crafted malicious ghostwriting scenarios across multiple
               domains and generators.},

  abstract  = {The automatic and manual annotation of unstructured corpora is
               a daily task in various scientific fields, which is supported
               by a variety of existing software solutions. Despite this variety,
               there are currently only limited solutions for visualizing annotations,
               especially with regard to dynamic generation and interaction.
               To bridge this gap and to visualize and provide annotated corpora
               based on user-, project- or corpus-specific aspects, Unified Dynamic
               Annotation Visualizer (UDAV) was developed. UDAV is designed as
               a web-based solution that implements a number of essential features
               which comparable tools do not support to enable a customizable
               and extensible toolbox for interacting with annotations, allowing
               the integration into existing big data frameworks.},

  keywords  = {Topic Evolution, Topic Network,Time-aware Networks, Temporal Autocorrelation, Project Gutenberg, satek},
  abstract  = {Although temporal topic modeling has been widely applied to scientific
               and legal texts, literary corpora have largely been overlooked
               in this regard. To address this issue, we analyze topic evolution
               in a subset of the Project Gutenberg (PG) corpus. We model this
               subset as a sequence of topic networks that capture the emergence,
               persistence, and interaction of thematic structures over decades.
               Using supervised topic representations, we predict nodes (topics)
               and edges (topic pairings) to forecast future topics and their
               co-occurrence. Our experiments demonstrate moderate to strong
               temporal persistence in topic connectivity patterns across three
               topic systems, with ROC-AUC and AP values consistently above 0.85.
               We find that the temporal span of topic networks significantly
               impacts predictive performance: longer spans improve the stability
               and recall of topic presence, while shorter spans better capture
               evolving topic relationships. Overall, our findings demonstrate
               the predictability of topics in literary texts over time.},
