Breakpoint chunking scores si against si+1 to identify subject shifts. In contrast, a pseudo-instruction scores every si against a document-level anchor to identify utility. This is particularly effective for filtering out boilerplate content that appears similar across segments but is irrelevant to the document’s core intent. A weak answer often incorrectly claims the pseudo-instruction is simply ‘more semantic’ without explaining the mechanism of anchor-based scoring or why mean-based thresholding is used.
