Hello Pranab, This recommendation is user to item recommendation. Now I wan to develop Item to Item recommendation i.e. recommendation for similar products .Can you help me with this? What should I refer from your tutorial?

pranab commented 9 years ago

What you have done using tutorial.txt is recommendation with collaborative filtering using item to item correlation. By item to item recommendation, if you mean content based recommendation based on item feature similarity, you could follow the tutorial prod_similarity_tutorial.txt.

Hello Pranab, What input should I give to TextAnalyzer.I didn't find sample input or any input format for this.

pranab commented 9 years ago

Same input as you would give to the main map reduce SameTypeSimilarity. TextAnalyzer is a pre processor for any text attribute that you may have. It does normalization of text data i.e. stemming . stop word removal etc. This blog has the details https://pkghosh.wordpress.com/2011/12/15/similarity-based-recommendation-text-analytic/
