Lesson 2: Structure, semantic and proposition chunking

Module 3 · Lesson 2 · About 45 minutes · Needs: Lesson 1 of this module (recursive splitting and the evidence check)

The situation

Lesson 1's recursive splitter cut the C70 error table between rows, and the moved rows lost their header. Kwame found the same in the spare-parts price list: the row for the P9 filter, FLT-P9-HEPA, lands in a chunk with no column names.

Kwame has also read about cleverer methods: cutting where the meaning changes, and rewriting text as single facts. Grace wants one chunker for Hollin Answers and a reason for choosing it. This lesson builds the options and measures them on the same questions. All Hollin data is simulated.
