Why Faceted Navigation?
  • Most things can be classified in more than one way.
  • Most organizational systems do not handle this well.
  • Example: Animal Classification

Locomotion

Diet

the problem with hierarchy
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

The Problem with Hierarchy

start

the idea of facets
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

  • Combine faceted navigation and search

Our Project
  • Major challenges our application seeks to address:
    • Faceted navigation and search
    • Automatic resource annotation
    • User preference identification and preference-based recommendation
automatic resource annotation
Automatic Resource Annotation
  • Using OneNote API, get the text
  • Clean the text
  • Annotated based on frequency and descriminative frequency
  • Clustering
