What are the differences between various ranking algorithms?

Ranking algorithms are methods used to order items based on certain criteria. Common types include PageRank, TF-IDF, and collaborative filtering. Each has its strengths and weaknesses depending on the application.

Can you explain how PageRank works?

PageRank works by analyzing the quantity and quality of links to a webpage to determine its importance. The more links pointing to a page, especially from high-authority sites, the higher its rank.

What about TF-IDF? How is it different?

TF-IDF stands for Term Frequency-Inverse Document Frequency. It measures how important a word is to a document in a collection. Unlike PageRank, it focuses on the content of the documents rather than their link structure.

Which algorithm is best for e-commerce product recommendations?

For e-commerce, collaborative filtering is often effective as it recommends products based on user behavior and preferences, leveraging the buying patterns of similar users.
