Reap the Wild Wind: Detecting Media Storms in Large-Scale News Corpora

no code implementations14 Apr 2024 Dror K. Markus, Effi Levi, Tamir Sheafer, Shaul R. Shenhav

Both the method and dataset offer the basis for comprehensive empirical research into the concept of media storms, including characterizing them and predicting their outbursts and durations, in mainstream media or social media platforms.

Factoring Hate Speech: A New Annotation Framework to Study Hate Speech in Social Media

no code implementations7 Nov 2023 Gal Ron, Effi Levi, Odelia Oshri, Shaul R. Shenhav

In this work we propose a novel annotation scheme which factors hate speech into five separate discursive categories.

Detecting Narrative Elements in Informational Text

1 code implementation Findings (NAACL) 2022 Effi Levi, Guy Mor, Tamir Sheafer, Shaul R. Shenhav

For this purpose, we designed a new multi-label narrative annotation scheme, better suited for informational text (e. g. news media), by adapting elements from the narrative theory of Labov and Waletzky (Complication and Resolution) and adding a new narrative element of our own (Success).

A Decomposition-Based Approach for Evaluating Inter-Annotator Disagreement in Narrative Analysis

no code implementations11 Jun 2022 Effi Levi, Shaul R. Shenhav

For this purpose, we present a method for a conceptual decomposition of an existing annotation into two separate levels: (1) \textbf{whether} or not a narrative plot exists in the text, and (2) \textbf{which} plot elements exist in the text.

CompRes: A Dataset for Narrative Structure in News

no code implementations9 Jul 2020 Effi Levi, Guy Mor, Shaul Shenhav, Tamir Sheafer

We describe the process in which the dataset was constructed: first, we designed a new narrative annotation scheme, better suited for news media, by adapting elements from the narrative theory of Labov and Waletzky (Complication and Resolution) and adding a new narrative element of our own (Success); then, we used that scheme to annotate a set of 29 English news articles (containing 1, 099 sentences) collected from news and partisan websites.

Computing Word Classes Using Spectral Clustering

Behavior-Based Machine-Learning: A Hybrid Approach for Predicting Human Decision Making

no code implementations30 Nov 2016 Gali Noti, Effi Levi, Yoav Kolumbus, Amit Daniely

A large body of work in behavioral fields attempts to develop models that describe the way people, as opposed to rational agents, make decisions.

Edge-Linear First-Order Dependency Parsing with Undirected Minimum Spanning Tree Inference

no code implementations ACL 2016 Effi Levi, Roi Reichart, Ari Rappoport

The run time complexity of state-of-the-art inference algorithms in graph-based dependency parsing is super-linear in the number of input words (n).
