Dialectic: Enhancing Text Input Fields with Automatic Feedback to Improve Social Content Writing Quality.

Modern social media relies on high quality user generated writing such as reviews, explanations, and answers. In contrast to standard validation to provide feedback for structured inputs (e.g., dates, email addresses), it is difficult to provide timely, high quality, customized feedback for free-form text input. While existing solutions based on crowdsourced feedback (e.g., up-votes and comments) can eventually produce high quality feedback, they suffer from high latency and costs, whereas fully automated approaches are limited to syntactic feedback that does not address text content. We introduce Dialectic, an end-to-end extensible system that simplifies the process of creating, customizing, and deploying content-specific feedback for free-text inputs. Our main observation is that many services already have a corpus of crowdsourced feedback that can be used to bootstrap a feedback system. Dialectic initializes with a corpus of annotated free-form text, automatically segments input text, and helps developers rapidly add domain-specific document quality features as well as content-specific feedback generation functions to provide targeted feedback to user inputs. Our user study shows that Dialectic can be used to create a feedback interface that produces an average of 14.4% quality improvement of product review text, over 3x better than a state-of-the-art feedback system.
