Plot Retrieval as an Assessment of Abstract Semantic Association (2024.acl-srw)

Copied to clipboard

Challenge: Existing information retrieval datasets cannot capture abstract semantic associations well.
Approach: They propose a task that retrieves relevant plots from the book for a query using a labeled dataset.
Outcome: The proposed task can be used to evaluate the performance of IR models on the novel task Plot Retrieval.
Towards Better Graph-based Cross-document Relation Extraction via Non-bridge Entity Enhancement and Prediction Debiasing (2024.findings-acl)

Copied to clipboard

Challenge: Existing studies on relation extraction ignore non-bridge entities, leading to bias during inference.
Approach: They propose a graph-based cross-document Relation Extraction model with non-bridge entity enhancement and prediction debiasing that integrates non-cross entities with target entities and bridge entities.
Outcome: The proposed model outperforms baseline models on open and closed datasets.
Word-Node2Vec: Improving Word Embedding with Document-Level Non-Local Word Co-occurrences (N19-1)

Copied to clipboard

Challenge: Existing word embedding algorithms make a strong assumption that words are semantically related only if they co-occur locally within a window of fixed size.
Approach: They propose a graph-based word embedding method that relies on locality to capture the semantic association between words that co-occur frequently but non-locally within documents.
Outcome: The proposed method outperforms word2vec and glove on a range of different tasks, such as predicting word-pair similarity, word analogy and concept categorization.
Perform like an Engine: A Closed-Loop Neural-Symbolic Learning Framework for Knowledge Graph Inference (2022.coling-1)

Copied to clipboard

Challenge: Existing knowledge graphs are incomplete and therefore lack interpretability.
Approach: They propose a closed-loop neural-symbolic learning framework EngineKG to address the natural incompleteness of knowledge graphs.
Outcome: The proposed model outperforms baselines on link prediction tasks on four real-world datasets.
TRAVEL: Tag-Aware Conversational FAQ Retrieval via Reinforcement Learning (2023.emnlp-main)

Copied to clipboard

Challenge: Existing methods aim to fully utilize the dynamic conversation context to enhance the semantic association between the user query and FAQ questions, but they are limited by noise and e.g., users may click questions they don't like, leading to inaccurate semantics modeling.
Approach: They propose to introduce tags of FAQ questions to reduce noise in the conversation context and integrate them into a reinforcement learning framework to minimize the negative impact of irrelevant information.
Outcome: The proposed method can eliminate irrelevant information and minimize negative impact of irrelevant information in the dynamic conversation context.
Reasoning with Multimodal Sarcastic Tweets via Modeling Cross-Modality Contrast and Semantic Association (2020.acl-main)

Copied to clipboard

Challenge: Existing methods for sarcasm detection rely on text data, but are insufficient to detect multimodal sarcasm.
Approach: They propose a method for modeling cross-modality contrast in the associated context by constructing the Decomposition and Relation Network.
Outcome: The proposed model can detect sarcasm in multimodal tweets using a dataset .
