Title: Relation Clustering in Narrative Knowledge Graphs
Authors: Simone Mellace, K Vani, Alessandro Antonucci
Abstract summary: relational sentences in the original text are embedded (with SBERT) and clustered in order to merge together semantically similar relations. Preliminary tests show that such clustering might successfully detect similar relations, and provide a valuable preprocessing for semi-supervised approaches.

Abstract: When coping with literary texts such as novels or short stories, the extraction of structured information in the form of a knowledge graph might be hindered by the huge number of possible relations between the entities corresponding to the characters in the novel and the consequent hurdles in gathering supervised information about them. Such issue is addressed here as an unsupervised task empowered by transformers: relational sentences in the original text are embedded (with SBERT) and clustered in order to merge together semantically similar relations. All the sentences in the same cluster are finally summarized (with BART) and a descriptive label extracted from the summary. Preliminary tests show that such clustering might successfully detect similar relations, and provide a valuable preprocessing for semi-supervised approaches.

Intelligent Multi-Document Summarisation for Extracting Insights on Racial Inequalities from Maternity Incident Investigation Reports [0.8609957371651683]
In healthcare, thousands of safety incidents occur every year, but learning from these incidents is not effectively aggregated. This paper presents I-SIRch:CS, a framework designed to facilitate the aggregation and analysis of safety incident reports. The framework integrates concept annotation using the Safety Intelligence Research (SIRch) taxonomy with clustering, summarisation, and analysis capabilities.

`Keep it Together': Enforcing Cohesion in Extractive Summaries by Simulating Human Memory [22.659031563705245]
In this paper, we aim to enforce cohesion whilst controlling for informativeness and redundancy in summaries. Our sentence selector simulates human memory to keep track of topics. It is possible to extract highly cohesive summaries that nevertheless read as informative to humans.

SNaC: Coherence Error Detection for Narrative Summarization [73.48220043216087]
We introduce SNaC, a narrative coherence evaluation framework rooted in fine-grained annotations for long summaries. We develop a taxonomy of coherence errors in generated narrative summaries and collect span-level annotations for 6.6k sentences across 150 book and movie screenplay summaries. Our work provides the first characterization of coherence errors generated by state-of-the-art summarization models and a protocol for eliciting coherence judgments from crowd annotators.

RelationPrompt: Leveraging Prompts to Generate Synthetic Data for Zero-Shot Relation Triplet Extraction [65.4337085607711]
We introduce the task setting of Zero-Shot Relation Triplet Extraction (ZeroRTE) Given an input sentence, each extracted triplet consists of the head entity, relation label, and tail entity where the relation label is not seen at the training stage. We propose to synthesize relation examples by prompting language models to generate structured texts.

Cross-Supervised Joint-Event-Extraction with Heterogeneous Information Networks [61.950353376870154]
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.
