How to Match Amazon / CJ / Linkshare Products: A Guide for Data Scientists
In today’s world of big data, the ability to match products across multiple platforms such as Amazon, CJ (Commission Junction), and Linkshare (Rakuten) can prove invaluable. Whether you’re looking to build a comparison shopping engine or conducting a market research, understanding how to associate products from various affiliate networks is crucial. This guide will walk you through the process, step by step.
1. Understanding Product Identifiers
Each platform uses unique identifiers for their products.
- Amazon: Amazon uses ASIN (Amazon Standard Identification Number), a 10-character alphanumeric code. For books, the ASIN is the same as the book’s ISBN.
- CJ: Products in CJ are identified with a PID (Publisher ID) and an AID (Advertiser ID).
- Linkshare: Linkshare uses MID (Merchant Identification Number) and PID (Product ID).
2. Gathering Product Data
To match products, you’ll first need to gather product data from each platform. This can be done using the respective APIs:
Each API provides access to product details like title, description, category, brand, and price.
3. Matching Strategy
Matching products across platforms is a complex task. There isn’t a universal identifier that can be used. Hence, you need to create a matching strategy, which could be any combination of the following:
- Title Matching: This involves comparing the titles of products. However, titles can vary slightly across platforms. To handle this, you can use a technique known as ‘fuzzy matching’ that finds matches even when they are less than 100% similar.
- Description Matching: This involves comparing product descriptions. This can be challenging due to the different lengths and details in descriptions across platforms. You can use natural language processing (NLP) techniques to extract meaningful information from descriptions.
- Brand Matching: If the brands are provided, they can be a reliable way of matching products. However, ensure that brand names are normalized before comparing (e.g., ‘LG’ and ‘L.G.’ should be considered the same).
4. Implementing the Matching Algorithm
Once your strategy is defined, you can implement your matching algorithm. A common approach is to use a machine learning technique such as logistic regression or decision trees. The Python libraries scikit-learn and pandas are excellent tools for this.
Here is a simplified pseudo-code of what your matching algorithm might look like:
for product in Amazon_products:
for target_product in CJ_products + Linkshare_products:
if fuzzy_match(product.title, target_product.title) > threshold:
if NLP_match(product.description, target_product.description) > threshold:
if brand_normalize(product.brand) == brand_normalize(target_product.brand):
match_products(product, target_product)
5. Evaluating and Improving Your Model
After implementing your model, evaluate its performance using a manually matched test set. If the results are unsatisfactory, you might need to optimize your matching strategy or use a more sophisticated machine learning model.
Product matching is a complex but rewarding task. It requires understanding of different platforms' APIs, effective matching strategy, and implementation of machine learning algorithms. By following this guide, you will be well on your way to solving this challenging problem.
Remember to always respect the usage policies of the APIs and platforms you are using. Happy coding!
