Nudging Grocery Shoppers to Make Healthier Choices

Despite the rampant increase in obesity rates and concomitant increases in rates of mortality from heart disease, cancer and diabetes, getting the general public to adopt a healthy diet has proven to be challenging for a variety of reasons. In this paper, we describe Foodle, a research project aimed at providing automated, personalized and goal-driven dietary guidance to users based on their grocery receipt data, by leveraging the availability of digital receipts for grocery store purchases. We discuss challenges faced, the current state of the project, and directions for future work.

Presentation of structured documents without a style sheet

In order to present most XML documents for human consumption, formatting information must be introduced and applied. Formatting is typically done through a style sheet, however, it is conceivable that one could wish to view the document without having a style sheet (either because a style sheet does not exist, or is unavailable, or is inappropriate for the display device). This paper describes a method for formatting structured documents without a provided style sheet. The idea is to first analyze the document to determine structures and features that might be relevant to style decisions. A transformation can be constructed to convert the original document to a generic form that captures the semantics that will be expressed through formatting and style. In the second stage styling is applied to the structures and features that have been discovered by applying a pre-defined style sheet for the generic form. The document instance, and if available, the corresponding schema or DTD can be analyzed in order to construct the transformation. This paper will describe the generic form used for formatting and techniques for generating transformations to it.
