A counterexample to Thiagarajan's conjecture on regular event structures [PDF]
, 2017 We provide a counterexample to a conjecture by Thiagarajan (1996 and 2002) that regular event structures correspond exactly to event structures obtained as unfoldings of finite 1-safe Petri nets.

Graph Convolution Over Multiple Latent Context-Aware Graph Structures for Event Detection
IEEE Access, 2020 Event detection is a particularly challenging problem in information extraction. The current neural network models have proved that dependency tree can better capture the correlation between candidate trigger words and related context in the sentence ...

On the Integration of Dative Adjuncts into Event Structures in Yapa Languages
Languages, 2021 Warlpiri and Warlmanpa (Ngumpin-Yapa languages of Australia) exhibit a complex predicate construction in which a class of preverbs introduces a single argument that is not shared by the argument structure of the inflecting verb, nor is there necessarily ...

Comparing neural models for nested and overlapping biomedical event detection
BMC Bioinformatics, 2022 Background Nested and overlapping events are particularly frequent and informative structures in biomedical event extraction. However, state-of-the-art neural models either neglect those structures during learning or use syntactic features and external ...

Relating Reversible Petri Nets and Reversible Event Structures, categorically [PDF]
Logical Methods in Computer ScienceCausal nets (CNs) are Petri nets where causal dependencies are modelled via inhibitor arcs. They play the role of occurrence nets when representing the behaviour of a concurrent and distributed system, even when reversibility is considered. In this paper

PASBio: predicate-argument structures for event extraction in molecular biology
BMC Bioinformatics, 2004 Background The exploitation of information extraction (IE), a technology aiming to provide instances of structured representations from free-form text, has been rapidly growing within the molecular biology (MB) research community to keep track of the ...

Mantichora, 2020 By asking partakers to ingest, relish, internalize, and personalize the event, engaging partakers as co-creators of the event, focusing on affect, and creating dramaturgical structures that allow partakers to savor and digest, site-based digital ...

Heidelberger Jahrbücher Online, 2020 A single event is not sufficient, to identify a structure. Only the repetition of similar events can lead to an understanding of the underlying structure.

Denotational, Causal, and Operational Determinism in Event Structures [PDF]
, 1995 Determinism is a theoretically and practically important concept in labelled transition systems and trees. We study its generalisation to event structures.

Revista Linguística, 2020 In Aguiar (2018), from a corpus of Latin predicates in which there is incorporation of prepositions as prefixes, it was pointed out that these prepositions, which head spatial expressions, select the arguments of the analyzed structures. In this article,
