A Case For Interaction:

A Study of Interactive Information Retrieval Behavior and Effectiveness

By Jürgen Koenemann and Nicholas J. Belkin (1996)

Presented by John Clougherty

John Clougherty2

Experiment to Measure Effectiveness of Relevance

Feedback and User Interaction

John Clougherty3

Relevance Feedback and User Interaction Improves Retrieval

Effectiveness

Relevance feedback increased retrieval effectiveness

Increased user interaction with relevance feedback made interactions more efficient

John Clougherty4

Exponential Number of New Users are Gaining Access to IR

Tools

Information is everywhere and it’s availability is growing rapidly

Anyone with a Computer/Smartphone/Tablet can use Bing to Google something

New users have none or minimal training

John Clougherty5

Increase in Computerized Tools to Support User’s Information

Need

User’s have an information need

Search engines are designed to provide that information need

Improvements in search engines are being developed every day

Speed, Best-match, Relevance, Flexibility, Push and Pull

Novice IR System Users Perform Query Reformulation

INQUERY System

Novice Users

2000 Documents

Two Topics

Precision@30 and Recall

John Clougherty7

Four Levels of Information Retrieval System

2. Opaque

Hidden Effect of Relevance Feedback

No User Interaction

4. Penetrable

Visible Effect of Relevance Feedback

User Interaction with Feedback

1. Baseline

No Relevance Feedback

3. Transparent

Visible Effect of Relevance Feedback

No User Interaction

John Clougherty8

Penetrable System Performed Best for Precision@30 and Number of

Iterations

John Clougherty9

Relevance Feedback is Heavily Utilized but User Interaction is

Minimal

Directly or Indirectly obtained by the user

Most relevance feedback algorithms are done implicitly

User interaction has yet to be implemented in a big way
