A comparison of neuroimaging entity/label categories/span of interest. The study on Shardlow et al. (2018) mainly focused on brain mechanism, especially multi-level brain structures. The study on Riedel et al. (2019) only took account of the experimental process. The study on Sheng et al. (2019) focused on brain mechanism and two experimental factors, including sensory stimuli or response and study participants’ medical problems. The study on Zhu et al. (2020) paid attention on pathology and mechanism of brain diseases. Our study is involved with the whole research process and extracted information is organized by events with rich semantics.
