A Survey on Event Causality Identification
In recent years, event causality identification has emerged as a key task in natural language processing. Given a text and the events it contains, the objective of event causality identification is to determine whether causal relationships exist among those events. This survey provides a comprehensive overview of the current state of research in event causality identification, covering core definitions, task formulations, related work, evaluation methodologies and benchmarks, as well as applications in specialized domains. We summarize the characteristics of current research, highlight open challenges, and discuss promising directions for future research.
Executive Impact: The Transformative Power of AI
This paper provides a systematic review of the task definition, methodological evolution, evaluation protocols, and domain-specific applications of event causality identification. As fundamental units of dynamic semantics, events pervade domains such as news, finance, healthcare, and social media, each exhibiting distinctive characteristics. Causal relations among events are often implicit yet crucial for reconstructing event narratives and supporting predictive reasoning. Despite notable progress, several key challenges remain unresolved: difficulty in recognizing implicit causality, ambiguous causal definitions and limited interpretability, and restricted application scope.

Linguistics-Based Methods
Early research primarily grounded in linguistic theories, relying on handcrafted rules or patterns to detect causal relations between events in text. These approaches typically focused on four core directions: cue phrases identification, template or pattern matching, dependency syntactic parsing, and formal logical rules. However, such methods generally suffered from heavy reliance on manual engineering. The effectiveness of cue phrases, pattern matching, and logical rules was highly constrained by the coverage of predefined lexicons and rule repositories, as well as the expertise of linguists, making them poorly generalizable to unseen linguistic expressions. Although dependency syntactic parsing methods could capture intra-sentential structural information, their feature extraction still required extensive hand-designed rules and lacked the capacity to model deeper semantic relationships.
Traditional Machine Learning Methods
As machine learning technologies have advanced, ECI has gradually shifted from methods relying on manual rules and templates to a data-driven paradigm that leverages feature extraction from data. ECI is typically modeled as a binary classification task, aiming to determine whether a causal relationship exists between two given events. Early research often integrated machine learning with linguistic knowledge for ECI. For instance, supervised learning methods utilized predefined causal trigger words (e.g., "because," "due to") as lexicons, employing Support Vector Machines (SVM) for classification. However, supervised learning methods heavily rely on large quantities of high-quality annotated data, which poses challenges in practical applications due to scarce annotations or difficulties in domain adaptation.
Deep Learning Methods
The advancement of deep learning has enabled ECI to transition gradually from traditional feature-engineering approaches toward end-to-end learning paradigms. The evolution of deep learning methods can be broadly divided into three phases: Traditional Neural Networks Methods, Pre-trained Language Models Based Methods, and Large Language Models (LLMs) Based Methods. Traditional neural network approaches remain valuable in scenarios with limited data or constrained computational resources, offering relatively lightweight architectures that can capture local or sequential patterns effectively. Pre-trained language model based methods, by contrast, excel at modeling rich contextualized text representations, demonstrating strong performance in handling diverse causal expressions and enabling effective cross-domain generalization. Most recently, LLMs based approaches have shown remarkable capabilities in capturing complex causal structures and attending to fine-grained linguistic nuances, thanks to their vast parameter scales and extensive pre-training on heterogeneous textual corpora.

Case Study: Financial Causality Extraction
In finance, identifying causal links between events enables more accurate forecasting of macroeconomic trends, offering actionable insights for investors and policymakers. Researchers proposed CAMEF, integrating time-series patterns with macroeconomic announcements and LLM-based counterfactual event augmentation to improve financial contagion analysis among BRICS stock markets during rare extreme events. This approach effectively addresses the scarcity of structured causal systems in finance by extracting cause and effect elements directly from unstructured financial text using universal dependencies and causal clue expressions to model nested causal relations, filling a gap in cross-lingual financial causality modeling.
Key Takeaway: AI-driven ECI improves financial forecasting and risk management by identifying complex causal relationships.
