You need to build a recommendation model that will suggest articles to readers that are similar to the articles they are currently reading. Which approach should you use?
Explanation:
The correct answer is B. Encoding all articles into vectors using word2vec and building a model that returns articles based on vector similarity is the optimal approach for this scenario. This method focuses on the content-based similarity of articles, which aligns with the requirement to suggest articles similar to the one the user is currently reading. Word2vec is effective in capturing semantic relationships between words and articles, allowing the model to recommend articles with similar contexts. Collaborative filtering (Option A) might recommend popular articles but not necessarily similar ones, while Options C and D would be less efficient and scalable for the given task.
