What happens if only manually-selected documents are coded?

When only manually-selected documents are coded, the implications are significant on various analytical outputs and the overall process.

Firstly, if the model is designed to learn and improve from coded documents, limiting the coding to only a subset meant for manual selection can hinder its ability to rebuild effectively. The model relies on a diverse range of coded data to enhance its training and refine its algorithms. By not incorporating the full scope of documents, the model may not update or rebuild as intended, which directly leads to the first part of the answer.

Secondly, the Prioritized Review Progress chart is a visualization tool used to track the effectiveness of the review process. This chart typically displays the relevance rate of reviewed documents, which helps assess the quality of coding over time. If only manually-selected documents are coded, there's a lack of comprehensive data reflecting the broader document set, resulting in an inability to accurately report relevance rates. This impacts the chart's functionality significantly, aligning with the second part of the answer.

Therefore, both consequences of the model not rebuilding effectively and the Prioritized Review Progress chart lacking relevance rate data illustrate the limitations imposed by only coding manually-selected documents. This comprehensive understanding confirms why the selected answer is C, as both statements are correct in describing the outcome of such a
