Hi,I have a reqiment,i need to calculate the relation between the terms.for example
Term1 Term2 relation(Weight)
iphone ipad 0.99999
iphone apple 0.88888
iphone food 0.33333
theare are a lot of term in my dictionary,about 600,000.it means that i must store about
600,000*(600,000-1) records.so it can not store in memory fully.
and when i search iphone ,i must get top N terms(order by relation desc,get top n).
does there have open source freamework to complete this reqiment?like Lucene to store and search the term's tf,df
