install hashedindex package available at pypi using

pip install hashedindex

1) to create inverted index and bigram index for a given file

python index_creation.py filepath

e.g.

python index_creation.py wiki_22

Following files will be generated(name of index files hard-coded in index_creation.py)

index.txt bigram_index.txt docids.txt

2) to test a query

define a query in query.txt file

to run query on vector space model:

python test_queries.py filepath_of_query filepath_of_inverted_index filepath_of_bigramindex filepath_of_docids

For Example

python test_queries.py query.txt index.txt bigram_index.txt docids.txt

to run query on model based on champion list:

python test_queries.py query.txt index.txt bigram_index.txt docids.txt 1

to run query on model based on phrasal query with vector space:

python test_queries.py query.txt index.txt bigram_index.txt docids.txt 2

Sample queries to be put in query.txt file: (one query at a time)
