Overview
K12-KGraph is a curriculum-aligned knowledge graph built from official People's Education Press (PEP) K-12 textbooks. It focuses on curriculum cognition, namely the structured understanding of how school knowledge is organized, connected, and sequenced.

dyck-k128-seq_len_2048-1B
Procedurally generated k-shuffle Dyck bracket sequences (Hu et al. 2025, arXiv:2502.19249), as flat uint16 token-id .bin files. Token ids are 0-based: opening bracket type i is id i and its matching close is i + k, so ids span [0, 2k) and the vocabulary is 2k = 256.

K12-KGraph
K12-KGraph is a curriculum-aligned knowledge graph built from official People's Education Press (PEP) K-12 textbooks. It focuses on curriculum cognition, namely the structured understanding of how school knowledge is organized, connected, and sequenced.
The current release covers mathematics, physics, chemistry, and biology across primary, middle, and high school, and includes three resources derived from the same graph:
K12-KGraph: the core knowledge graph
