1.

How do you characterize traditional information retrieval systems?

2.

What does a ranking algorithm do? How this algorithm related to traditional
information retrieval systems?

3.

In the classic models of IRS, namely Bool
ean, Vector, and Probabilistic models,
explain how these models differs to each other?

4.

What are the differences between retrieval technique versus browsing technique?

5.

What are the differences between ad hoc retrieval technique versus filtering
retrieval te
chnique?

6.

How do you characterize Fuzzy Set model and Extended Boolean Model. How
these models improve Boolean model?

7.

How do you characterize Generalized Vector Space model, Latent Semantic
Indexing model and Neural Network model? How these models improve V
ector
model?

8.

How do you characterize Bayesian Networks model, Inference Network model,
and Belief Network model? How these models improve Probabilistic model?

9.

What are the differences between classical model versus structured text retrieval
model?

10.

How do y
ou characterize Browsing model?

11.

In the browsing model, flat, structured guided, and hypertext models, explain how
these models differ to each other.
