Top‑k queries (“return the k most relevant items”) are a cornerstone of many real‑time analytics applications, ranging from online recommendation systems to network intrusion detection. Conventional approaches either (i) scan the entire data stream, incurring linear time, or (ii) maintain costly sketch structures that suffer from high approximation error when the data distribution drifts.

I need to check if there's any existing public information about this. If it's a social media handle, I could look up the user's profile on platforms like Twitter, Instagram, etc. If it's a subreddit, searching on Reddit's database might help. However, without explicit context, it's challenging to determine the exact domain. Top‑k queries (“return the k most relevant items”)
