and its participating entities in news articles?

Methodology
1: The Concentric Nature of News Semantic Snapshots: Knowledge Extraction for Semantic Annotation of News Items, García, José Luis Redondo, Giuseppe Rizzo, and
Raphaël Troncy, 2015
Data
● ECB+ dataset2
annotated by experts
2 : Guidelines for ECB+ annotation of events and their coreference, Cybulska, Agata and Vossen, Piek, 2014
Annotation example
.. another person in 1999 while she visited him in prison .
Relations
Causal relation : pulled on → fleeing
Temporal relation : Monday → pulls on
Preliminary Experiment
● Approach
○ Occurrence
● Problems
○ Similar words
○ Stop words
○ Similar scores
Main Experiment
● Approach to solve problems
○ Lemmatization/stemming
○ Similarity comparison
○ TF-IDF
○ Considering temporal and causal relations between events
○ Core and Crust scores
■ Core: Relations with all entities in Core
■ Crust: Relation with an entity in Core
Crowdsourcing for Links (Event - Actor/Place/Time)
Final Results
● Evaluation:
○ F-score events : > 0.5
Discussion & Conclusion
● Corereference
● Limited scores for actors, locations and time periods
○ Better NSS models
○ Change of scores for events
Research Question:
Can we determine a relevance score of events and its participating entities in news articles?
Answer:
Yes, but…
