LLM-Based Semantic Refinement

This core component introduces a novel approach to overcome the challenge of representing complex bundle semantics. By leveraging Large Language Models (LLMs), LLMCBR accurately summarizes and encodes bundle-level knowledge from textual item descriptions. A lightweight adaptation strategy then bridges this semantic representation with crucial collaborative signals, allowing the system to benefit from both deep semantic understanding and interaction data for superior recommendation quality.

Multi-View Preference Modeling

LLMCBR recognizes that user preferences inherently involve two correlated views: the bundle-view (BV) and the item-view (IV). The BV encompasses user-bundle and bundle-item interactions, focusing on bundle-level preferences. The IV covers user-item and bundle-item affiliations, highlighting item-level preferences. By independently modeling each view, LLMCBR captures view-specific knowledge, enabling effective information collaboration and a more comprehensive understanding of user interests.

Multi-Grained Preference Modeling

To capture both local and global user interests, LLMCBR partitions each view into distinct granularities: fine-grained and coarse-grained. Fine-grained embeddings capture detailed local preferences, while coarse-grained embeddings leverage ego graphs and additional side information to capture broader global patterns. This multi-grained approach mitigates biases from relying solely on local information and enriches the understanding of diverse consumer behaviors.

Cross-Granularity Cross-View Contrastive Learning

This module uses a sophisticated multiple contrastive instance mechanism to regulate the influence of different granularities and views. By designing cross-granularity (fine vs. coarse) and cross-view (bundle vs. item) contrastive learning strategies, LLMCBR ensures knowledge from various dimensions guides the modeling process. This mechanism empowers the model to comprehend complex consumer behaviors across different levels of detail and perspectives, leading to more accurate and robust recommendations.

Multi-View Data Integration
Stratification into Granularities
Multi-Grained Details Acquisition
Cross-Granularity Collaboration

The framework stratifies each view into multiple granularities (fine-grained and coarse-grained) to capture both local preferences and global patterns. This multi-grained approach enhances the precision of recommendations by providing a more comprehensive understanding of user interests.

LLMCBR (Full Model) Baseline Approaches
  • LLM-based semantic encoding
  • Multi-view collaboration (U-B, U-I, B-I)
  • Multi-grained (fine & coarse) learning
  • Cross-granularity and cross-view CL
  • State-of-the-art performance across datasets
  • Limited semantic understanding
  • Partial multi-view modeling
  • Lack of multi-grained detail
  • Suboptimal correlation modeling
  • Lower performance

LLMCBR's unique integration of multi-view and multi-grained learning, coupled with LLM-based semantic refinement, consistently outperforms state-of-the-art baselines. This comparative advantage stems from its ability to capture a richer, more nuanced understanding of user preferences and bundle complexities.

Optimizing Graph Connectivity: The Role of Hop Number

The ablation study on hop number (Table 4) revealed that performance initially improves with increasing k (up to k=2), as more extensive neighbor sets provide comprehensive information. However, performance degrades when k is too large (e.g., k=3), indicating that excessive neighbor nodes introduce noise, obscuring useful signals. This highlights the importance of carefully tuning graph connectivity to balance information richness with noise reduction for optimal recommendation quality.

Optimal k=2 balances information and noise.
