System Technical Architecture and Methodology
Our solution integrates multiple advanced technical modules, ranging from data preprocessing to deep semantic matching, and is supported by various scientific methodologies. The following outlines the specific technical architecture and methodology:
1. Data Preprocessing and Adaptive Clustering
At this stage, the system leverages Python and its powerful open-source libraries to integrate and clean pricing data collected from various e-commerce platforms and distributors. Key technologies and methods include:
Data Processing Tools
- Pandas: Used for reading and merging CSV files, removing extraneous symbols through regular expressions, and converting price data into numerical formats, ensuring the accuracy of e-commerce data.
- NumPy: Enables efficient numerical calculations and array operations, providing precise computational support for subsequent AI models.
Clustering Techniques and Statistical Evaluation
- K-Means Clustering: Based on the principle of minimizing the Within-Cluster Sum of Squares (WCSS), this method categorizes home appliance products into natural groupings according to price characteristics.
- Evaluation Metrics:
- Silhouette Score: Measures the relative distance of data points within clusters compared to neighboring clusters, reflecting internal cohesion and external separation of clusters.
- Calinski-Harabasz Index: Assesses clustering effectiveness using the ratio of inter-cluster variance to intra-cluster variance; higher values indicate better clustering.
- Davies-Bouldin Index: Evaluates the similarity between clusters; lower values signify greater differentiation between clusters.

Standardization Method
- Z-Score Standardization: This method standardizes various evaluation metrics, removing unit scale effects to allow direct integration of multiple indicators, thus enhancing the objectivity of decision-making.
2. Keyword-based Text Classification and E-commerce Data Matching
Since product descriptions may vary across different e-commerce platforms, the system utilizes rule-based text classification techniques to ensure data consistency across channels. The primary methods include:
Text Classification Tools
- Using Python’s string processing, regular expressions, and set operations to quickly identify predefined keywords in product names.
Keyword-based Classification
- Standard Products: Keywords such as “Basic Model,” “Economy Edition,” and “No Additional Functions,” representing products with basic functionalities.
- Fully-equipped Products: Keywords like “High-end Edition,” “Full Functions,” and “Includes Remote Control and Accessories,” indicating richly equipped products.
- Accessory-specific: Keywords such as “Accessory Parts,” “Additional Remote Control,” and “Expansion Components,” categorizing supplementary product accessories.
Set and Intersection Theory
- Applying set operations to match keywords in product descriptions accurately, ensuring products from different e-commerce platforms can be precisely compared based on core configurations, thus eliminating description discrepancies affecting pricing analysis.
3. Application of Artificial Intelligence (AI) and Large Language Models (LLM)
To address the challenges of processing unstructured textual data on e-commerce platforms, we introduce advanced AI techniques utilizing large language models (LLM) for deep semantic matching. The core technologies and processes include:
Large Language Model Technology
- Transformer Architecture: Leveraging the attention mechanism to capture relationships among keywords in texts, enabling contextual semantic understanding, which is central to current AI technologies.
- Pre-training and Fine-tuning: Models undergo pre-training on extensive textual data and are subsequently fine-tuned specifically for comparing home appliance product descriptions, enabling effective handling of heterogeneous textual data from various e-commerce platforms.
Matching Process and Prompt Design
- Prompt Construction: Combining baseline products, preliminarily filtered product lists, and strict matching rules (such as excluding non-core factors like color, packaging, batch, etc.) into prompt texts, ensuring the AI focuses solely on core product configurations and features.
- Semantic Understanding and Decision Making: Using lightweight models from the GPT series (e.g., “o1-mini”) for deep semantic analysis of e-commerce product descriptions to identify and correct pricing discrepancies resulting from subtle description variations, thus achieving data consistency and accuracy.
Application of Core Mathematical and Statistical Theories in E-commerce Price Management
This solution fully utilizes the following mathematical and statistical theories, integrated with AI technology, to create a comprehensive e-commerce pricing management system:
