Design Mining the Web

Ranjitha Kumar, Arvind Satyanarayan, Cesar Torres, Maxine Lim, Salman Ahmad, Scott Klemmer, Jerry Talon

Advances in data mining and knowledge discovery have transformed the way Web sites are designed. However, while visual presentation is an intrinsic part of the Web, traditional data mining techniques ignore render-time page structures and their attributes. This paper introduces design mining for the Web: using knowledge discovery techniques to understand design demographics, automate design curation, and support data-driven design tools. This idea is manifest in Webzeitgeist, a platform for large-scale design mining comprising a repository of over 100,000 Web pages and 100 million design elements. This paper describes the principles driving design mining, the implementation of the Webzeitgeist architecture, and the new class of data-driven design applications it enables.

Internet of Everday Things (2015) | David Culler

Reading stories and experiencing storytelling is formative to a child’s development and a critical tool for sense-making. As the Internet of Things develops, we see new opportunities to expand the aesthetics of storytelling. We introduce Smart- Storybook, an augmented environment (AE) application that controls the rich multimodal environment enabled by IoET to create interactive, engaging reading material. Smart Story- book contributes a content creation tool that synthesizes out- put with storylines. Upon reading time, the tool polls devices in a room for story enhancing capabilities (e.g. providing light, sound, smell). The desired story telling environment is resolved dynamically, providing a unique storytelling ex- perience based on available devices and services.

Structural Learning for Web Design

Machine Learning (2012) | Andrew Ng

Recursive neural networks (RNNs) have been successful for structured prediction in domains such as language and image processing. These techniques imposed structure onto sentences or images for more effective learning. However, in domains such as Web design, structure is explicitly embedded in the Document Object Model, so structured prediction can be done using the natural hierarchy of Web pages.

Structural Learning for Web Design

Data Visualization (2012) | Jeffrey Heer | Interactive Data Project

Exploring a design space must generally be done by manual inspection of many design examples. Visualizing designdata in an aggregate way can make this process more efficient, but as design data lies in a high-dimensional feature space, selecting the important elements to view is challenging. This work presents Charlotte, a system that enables exploration of Web designs represented in 1,713 dimensions by applying the concept of data portraits and generating visualizations that capture groups of pages with respect to a selected set of design principles. Charlotte demonstrates that meaningful patterns and trends among the design data can explored by using these principles to inform data-driven portraits.
