Designing a Model for Deliberation-based Learning
International Conference of the Learning Sciences
In political organizing, groups use deliberation to scope projects in which they will collaboratively design political actions and organizations. Despite its importance, we lack a model for teaching learners to scope highly open-ended political projects through deliberation. We designed, implemented, and evaluated deliberation-based learning (DBL), a novel model of learning environments that combines support for iterative design and deliberation, in a university design course.

In political organizing, groups use deliberation to scope projects in which they will collaboratively design political actions and organizations. Despite its importance, we lack a model for teaching learners to scope highly open-ended political projects through deliberation. We designed, implemented, and evaluated deliberation-based learning (DBL), a novel model of learning environments that combines support for iterative design and deliberation, in a university design course. We found the learning environment supported students to choose political issues, form teams, and scope detailed project proposals from scratch, by completing iterations of proposing ideas, raising questions, suggesting improvements, planning to-dos, seeking information, and updating their proposals. This study contributes DBL, a novel, empirically grounded model of learning environments for scoping design projects through deliberation, which can be further refined through multi-case studies across contexts. By understanding DBL, learning scientists can engage students in political organizing in their communities-a key to sustaining democracy. Just as learning scientists have long explored how to design learning environments for learning scientific inquiry as a method for explaining natural phenomena, in this paper, we explore how to design learning environments for learning deliberation as a method for scoping design projects in political organizing.

No More One Liners: Bringing Context into Emoji Recommendations
ACM Transactions on Social Computing
As emojis are increasingly used in everyday online communication such as messaging, email, and social networks, various techniques have attempted to improve the user experience in communicating emotions and information through emojis. Emoji recommendation is one such example in which machine learning is applied to predict which emojis the user is about to select, based on the user’s current input message.

As emojis are increasingly used in everyday online communication such as messaging, email, and social networks, various techniques have attempted to improve the user experience in communicating emotions and information through emojis. Emoji recommendation is one such example in which machine learning is applied to predict which emojis the user is about to select, based on the user’s current input message. Although emoji suggestion helps users identify and select the right emoji among a plethora of emojis, analyzing only a single sentence for this purpose has several limitations. First, various emotions, information, and contexts that emerge in a flow of conversation could be missed by simply looking at the most recent sentence. Second, it cannot suggest emojis for emoji-only messages, where the users use only emojis without any text. To overcome these issues, we present Reeboc (Recommending emojis based on context), which combines machine learning and k-means clustering to analyze the conversation of a chat, extract different emotions or topics of the conversation, and recommend emojis that represent various contexts to the user. To evaluate the effectiveness of our proposed emoji recommendation system and understand its effects on user experience, we performed a user study with 17 participants in eight groups in a realistic mobile chat environment with three different modes: (i) a default static layout without emoji recommendations, (ii) emoji recommendation based on the current single sentence, and (iii) our emoji recommendation model that considers the conversation. Participants spent the least amount of time in identifying and selecting the emojis of their choice with Reeboc (38% faster than the baseline). They also chose emojis that were more highly ranked with Reeboc than with current-sentence-only recommendations. Moreover, participants appreciated emoji recommendations for emoji-only messages, which contributed to 36.2% of all sentences containing emojis.

Interacting with Literary Style through Computational Tools
2020 CHI Conference on Human Factors in Computing Systems
Style is an important aspect of writing, shaping how audiences interpret and engage with literary works. However, for most people style is difficult to articulate precisely. While users frequently interact with computational word processing tools with well-defined metrics, such as spelling and grammar checkers, style is a significantly more nuanced concept. In this paper, we present a computational technique to help surface style in written text. We collect a dataset of crowdsourced human…
Style is an important aspect of writing, shaping how audiences interpret and engage with literary works. However, for most people style is difficult to articulate precisely. While users frequently interact with computational word processing tools with well-defined metrics, such as spelling and grammar checkers, style is a significantly more nuanced concept. In this paper, we present a computational technique to help surface style in written text. We collect a dataset of crowdsourced human judgments of style, derive a model of style by training a neural net on this data, and present novel applications for visualizing and browsing style across broad bodies of literature, as well as an interactive text editor with real-time style feedback. We study these interactive style applications with users and discuss implications for enabling this novel approach to style.
