Synthia: Visually Interpreting and Synthesizing Feedback for Writing Revision

Figure 1: This figure illustrates how SyntHia supports users in managing, interpreting, and synthesizing feedback for writing revisions. SyntHia decomposes large collections of feedback into interactive, configurable bubbles (A.1), allowing users to adjust visual encodings, such as clustering, color, size, and reflection arcs, to identify patterns and assess feedback helpfulness (A.2 & A.3). Bidirectional highlighting connects feedback to its original context (B.1), similar feedback units (B.2), and the relevant sentences in the text (B.3), helping users understand its meaning, relevance, and impact. Finally, SyntHia facilitates revision by enabling users to synthesize feedback into new drafts (C.1) and track revision versions (C.2), providing a non-linear, traceable interface for exploring alternative edits.
