Unsupervised Catalog Generation with Clustering, Reinforcement and More
This presentation will look at how you can generate product catalogs from ecommerce websites using just the homepage URL of the website. Techniques explored include URL clustering, regex generation, reinforcement learning and supervised classification.
Intro: What the problem is, why it’s useful and its roots in the Semantic Web movement.
Identifying Product URLs: The need to identify product pages from just their URLs. Using URL signatures + clustering + regex generation + supervised classification to solve this problem.
Spidering Strategy: Optimal strategy for spidering through the website to find product URLs, using reinforcement learning techniques.
Context Extraction: Techniques for extracting structured data from HTML + rendered webpages, notably through the use of bounding boxes. Then, we look at variation identification and extraction through the use of headless browsers.
