Conceptual Knowledge Reasoning for User Satisfaction Estimation in E-Commerce Dialogue Systems
This paper introduces CoRe-USE, a knowledge-enhanced model for estimating user satisfaction in e-commerce dialogue systems. By integrating conceptual knowledge reasoning from product knowledge graphs with contextual dialogue understanding, CoRe-USE accurately infers user concerns and provides more informative responses. Experiments on three real-world datasets demonstrate its superior performance and robustness compared to state-of-the-art baselines, especially in identifying user needs beyond mere sentiment.
Key Metrics & Impact
CoRe-USE significantly advances user satisfaction estimation in e-commerce, offering tangible improvements in accuracy, F1 score, and reasoning efficiency.

Conceptual Knowledge Reasoning
CoRe-USE introduces conceptual knowledge reasoning to understand product attributes and user concerns from e-commerce knowledge graphs like OpenBG. This goes beyond simple sentiment analysis to grasp *what* the user is asking about, preventing non-informative but friendly responses. It uses entities and relations to infer key attributes and concepts.

Knowledge-Enhanced USE
Hierarchical Dialogue Encoding
The model employs a hierarchical encoder, leveraging a Transformer architecture, to capture both turn-level (individual question-answer pairs) and dialogue-level (overall conversation flow) contextual information. This ensures a comprehensive understanding of multi-turn dialogues, which is crucial for accurate satisfaction estimation.

Knowledge Enhancement Module
This module integrates keywords extracted via conceptual reasoning, textual embeddings from the dialogue, and subject embeddings. It uses parallel multi-head attention mechanisms to fuse these distinct feature sets, allowing the model to focus on critical, informative aspects and dynamically adjust the influence of subject knowledge.

Robustness in Low-Resource & Multi-task Scenarios
CoRe-USE demonstrates strong performance even with limited training data (low-resource scenarios) and when jointly trained for multiple tasks (e.g., User Satisfaction Estimation and Dialogue Act Recognition). This highlights its practical applicability and stability in real-world customer service environments where data scarcity and diverse tasks are common.
Real-World Adaptability
In customer service, data can be sparse, and agents often handle multiple types of inquiries. CoRe-USE's design directly addresses these challenges. For instance, in low-resource settings, where only 500 dialogues were available, CoRe-USE still achieved superior results, proving its data efficiency. Furthermore, its multi-task capability means it can simultaneously predict user satisfaction and classify dialogue acts (e.g., user intent), offering a holistic solution for enterprise AI. This broad utility enhances its value for platforms needing flexible and robust AI agents.

Your AI Implementation Roadmap
A clear path to integrating advanced AI into your customer service operations, phase by phase.
Phase 1: Knowledge Graph Integration
Align your existing product catalog or internal knowledge bases with a structured knowledge graph. This involves entity linking and relation extraction to build the foundation for conceptual reasoning. (~2-4 Weeks)
Phase 2: Dialogue Data Preparation
Collect and preprocess historical dialogue data, ensuring it is annotated for user satisfaction and, if desired, dialogue acts. This data will be used to train and fine-tune the CoRe-USE model. (~4-6 Weeks)
Phase 3: Model Training & Fine-tuning
Train CoRe-USE using the integrated knowledge graph and dialogue data. Fine-tune pre-trained BERT models for domain-specific language understanding and optimize the hierarchical encoder. (~6-8 Weeks)
Phase 4: Deployment & A/B Testing
Deploy CoRe-USE in a controlled environment for A/B testing against existing satisfaction estimation methods. Monitor performance metrics and gather feedback for iterative improvements. (~3-5 Weeks)
Phase 5: Continuous Improvement & Expansion
Establish a feedback loop for continuous model improvement, regularly updating the knowledge graph and retraining with new data. Explore expansion to new product categories or languages. (Ongoing)
