• Abstract summary: This work describes a corpus of German-language documents which has been annotated with fine-grained geo-entities. It has also been annotated with a set of 15 traffic- and industry-related n-ary relations and events. The corpus consists of newswire texts, Twitter messages, and traffic reports from radio stations, police and railway companies.

• Abstract: Monitoring mobility- and industry-relevant events is important in areas such as personal travel planning and supply chain management, but extracting events pertaining to specific companies, transit routes and locations from heterogeneous, high-volume text streams remains a significant challenge. This work describes a corpus of German-language documents which has been annotated with fine-grained geo-entities, such as streets, stops and routes, as well as standard named entity types. It has also been annotated with a set of 15 traffic- and industry-related n-ary relations and events, such as accidents, traffic jams, acquisitions, and strikes. The corpus consists of newswire texts, Twitter messages, and traffic reports from radio stations, police and railway companies. It allows for training and evaluating both named entity recognition algorithms that aim for fine-grained typing of geo-entities, as well as n-ary relation extraction systems.

In this work, we explore how generative models combined with text describing the traffic system can be applied for traffic generation. We propose ChatTraffic, the first diffusion model for text-to-traffic generation.

We evaluate various state-of-the-art methods, and present their quantitative and qualitative results on OpenLane-V2 to indicate future avenues for investigating topology reasoning in traffic scenes.

  We focus on the role of named entities in content preservation for formality text style transfer. We collect a new dataset for the evaluation of content similarity measures in text style transfer. We perform an error analysis of a pre-trained formality transfer model and introduce a simple technique to use information about named entities to enhance the performance of baseline content similarity measures used in text style transfer.

  We propose a new task, key event detection at the intermediate level, aiming to detect from a news corpus key events. This task can bridge event understanding and structuring and is inherently challenging because of the thematic and temporal closeness of key events. We develop an unsupervised key event detection framework, EvMine, that extracts temporally frequent peak phrases using a novel ttf-itf score.

  Causality understanding between events is helpful in many areas, including health care, business risk management and finance. "Cause-Effect" relationships between natural language events continues to remain a challenge simply because it is often expressed implicitly. Our proposed methods achieve the state-of-art performance in three different data distributions and can be leveraged for extraction of a causal diagram.

  Joint-event-extraction is a sequence-to-sequence labeling task with a tag set composed of tags of triggers and entities. We propose a Cross-Supervised Mechanism (CSM) to alternately supervise the extraction of triggers or entities. Our approach outperforms the state-of-the-art methods in both entity and trigger extraction.
