Query: Understanding Human Reading Comprehension with Brain Signals   Reading comprehension is a complex cognitive process involving many human
brain activities. Plenty of works have studied the reading patterns and
attention allocation mechanisms in the reading process. However, little is
known about what happens in human brain during reading comprehension and how we
can utilize this information as implicit feedback to facilitate information
acquisition performance. With the advances in brain imaging techniques such as
EEG, it is possible to collect high-precision brain signals in almost real
time. With neuroimaging techniques, we carefully design a lab-based user study
to investigate brain activities during reading comprehension. Our findings show
that neural responses vary with different types of contents, i.e., contents
that can satisfy users' information needs and contents that cannot. We suggest
that various cognitive activities, e.g., cognitive loading, semantic-thematic
understanding, and inferential processing, at the micro-time scale during
reading comprehension underpin these neural responses. Inspired by these
detectable differences in cognitive activities, we construct supervised
learning models based on EEG features for two reading comprehension tasks:
answer sentence classification and answer extraction. Results show that it is
feasible to improve their performance with brain signals. These findings imply
that brain signals are valuable feedback for enhancing human-computer
interactions during reading comprehension.
