click click

4

 

 

Metal shears click here

 

 

 

 

 

a. Build q query likelihood LM for this document collection. Assume a mixture model between the documents and the collection with both weighted 0.5. MLE is used to estimate both as unigram models. Work out the model probabilities of the queries.

 

 

“click”, “shears”, and hence “click shears” for each document. Fill in these probabilities in the below table:

 

 

Query

 

 

Doc 1

 

 

Doc 2

 

 

Doc 3

 

 

Doc 4
