  1. Outline • Our Project • Why Faceted Navigation? • Demo

  2. Our Project • Major challenges our application seeks to address: • Faceted navigation and search • Automatic resource annotation and dynamic refinement • User preference identification and preference-based recommendation

  4. The Problem with Hierarchy • Inflexible • Force the user to start with a particular category • What if I don’t know the animal’s diet, but the interface makes me start with that category? • Wasteful • Have to repeat combinations of categories • Makes for extra clicking and extra coding • Difficult to modify • To add a new category type, must duplicate it everywhere or change things everywhere

  6. The Idea of Facets • Facets are a way of labeling data • A kind of Metadata (data about data) • Can be thought of as properties of items • Facets vs. Categories • Items are placed INTO a category system • Multiple facet labels are ASSIGNED TO items

  7. Easy Notes - Novel Feature • Combine faceted navigation and search

  8. Our Project • Major challenges our application seeks to address: • Faceted navigation and search • Automatic resource annotation • User preference identification and preference-based recommendation

  9. Automatic Resource Annotation • Using OneNote API, get the text • Clean the text • Annotated based on frequency and descriminative frequency • Clustering

  10. Our Project • Major challenges our application seeks to address: • Faceted navigation and search • Automatic resource annotation • User preference identification and preference-based recommendation

  11. User Preference Identification and Preference-based Recommendation • Login system • Manage the lowest level of information user wants
