Factorial User Modeling with Hierarchical Graph Neural Network for Enhanced Sequential Recommendation
2022 · arXiv (Cornell University)
Most sequential recommendation (SR) systems employing graph neural networks (GNNs) only model a user's interaction sequence as a flat graph without hierarchy, overlooking diverse factors in the user's preference. Moreover, the timespan between interacted items …

Generative Entity Typing with Curriculum Learning
2022
Entity typing aims to assign types to the entity mentions in given texts. The traditional classification-based entity typing paradigm has two unignorable drawbacks: 1) it fails to assign an entity to the types beyond the …

Negation Triplet Extraction with Syntactic Dependency and Semantic Consistency
2024 · arXiv (Cornell University)
Previous works of negation understanding mainly focus on negation cue detection and scope resolution, without identifying negation subject which is also significant to the downstream tasks. In this paper, we propose a new negation triplet …

BOOKWORLD: From Novels to Interactive Agent Societies for Story Creation
2025
Recent advances in large language models (LLMs) have enabled social simulation through multi-agent systems.Prior efforts focus on agent societies created from scratch, assigning agents with newly defined personas.However, simulating established fictional worlds and characters remain …

A Knowledge-Enhanced Deep Recommendation Framework Incorporating GAN-Based Models
2018
Although many researchers of recommender systems have noted that encoding user-item interactions based on DNNs promotes the performance of collaborative filtering, they ignore that embedding the latent features collected from external sources, e.g., knowledge graphs …
