• Abstract: HeidelTime is one of the most widespread and successful tools for detecting temporal expressions in texts. Since HeidelTime's pattern matching system is based on regular expression, it can be extended in a convenient way. We present such an extension for the German resources of HeidelTime: HeidelTime-EXT . The extension has been brought about by means of observing false negatives within real world texts and various time banks. The gain in coverage is 2.7% or 8.5%, depending on the admitted degree of potential overgeneralization. We describe the development of HeidelTime-EXT, its evaluation on text samples from various genres, and share some linguistic observations. HeidelTime ext can be obtained from https://github.com/texttechnologylab/heideltime.

  We introduce the Hierarchical Long Text Generation Benchmark (HelloBench) to evaluate Large Language Models' performance in generating long text. Based on Bloom's taxonomy, HelloBench categorizes long text generation tasks into five subtasks: open-ended QA, summarization, chat, text completion, and text generation. Besides, we propose Hierarchical Long Text Evaluation (HelloEval), a human evaluation method that significantly reduces the time and effort required for human evaluation.

  We introduce the TEI2GO models, matching HeidelTime's effectiveness but with significantly improved runtime. To train the TEI2GO models, we used a combination of manually annotated reference corpus and developed Professor HeidelTime'', a comprehensive weakly labeled corpus of news texts annotated with HeidelTime. Code, annotations, and models are openly available for community exploration and use.

  We present the first multi-dialect Bavarian treebank (MaiBaam) manually annotated with part-of-speech and syntactic dependency information in Universal Dependencies (UD) We highlight the morphosyntactic differences between the closely-related Bavarian and German and showcase the rich variability of speakers' orthographies. Our corpus includes 15k tokens, covering dialects from all Bavarian-speaking areas spanning three countries.

  We introduce Retrieval-Based Speculative Decoding (REST), a novel algorithm designed to speed up language model generation. Unlike previous methods that rely on a draft language model for speculative decoding, REST harnesses the power of retrieval to generate draft tokens. When benchmarked on 7B and 13B language models in a single-batch setting, REST achieves a significant speedup of 1.62X to 2.36X on code or text generation.

  We formulate text generation as progressively copying text segments from an existing text collection. Our approach achieves better generation quality according to both automatic and human evaluations. Our approach attains additional performance gains by simply scaling up to larger text collections.

Two types of time-aware prompts are investigated: (1) textual prompts that encode document timestamps in natural language sentences; and (2) linear prompts that convert timestamps into continuous vectors.

  Modern language models can generate high-quality short texts, but often meander or are incoherent when generating longer texts. Recent work in self-supervised learning suggests that models can learn good latent representations via contrastive learning. We propose one approach for leveraging constrastive representations, which we call Time Control.
