[Precoding]: A page where different coders independently code the data imported (randomly sampled) from the Coding library to the Test library. The content on the Precoding page is the same as on the formal Coding page, but the Precoding page is used for reliability test only. The left side of the Precoding page shows the textual data with the previously customized coding setting; the right side shows the detailed coding categories. Related keywords in the text will be auto-selected, and the words “Machine advoce” will be displayed beside the categorization options.
