simhash-java

A simple implementation of simhash algorithm by java.

Features:

1. compute the simhash of a string
   
2. compute the similarity between all the strins by build smart index, so We can deal with big data.
   

How to use:

run Main with inputfile and outputfile.

The format of inputfile(see src/test_in): one doc eachline with the utf8 charset.

The format of outputfile(see src/test_out):

start //start flag

first line // doc

sencode lien // doc1\tdist the dist is the hamming distance between doc and doc1

end //end flag

Future:

1. Build the project to a runnable jar.
   
2. Improve the performace under big data.
