Description

The article formalizes the integration of reading activity data and reading content data as a matrix multiplication between traditional reading logs and a matrix M encoding topic distributions across pages of the reading material. The article interprets "this multimodal integration ... as a matrix multiplication between traditional reading logs and a matrix M that encodes topic distributions across pages of the reading material". This reframes non-contextualized reading logs as an optimization problem of accurately estimating topic distributions across educational materials, enabling topic-based reading characteristics such as student topic preference vectors derived from l1-normalized reading time.
