CONCLUSION AND FUTURE WORK
Data in the form of reviews, opinions, feedback, remarks, and complaint treated as Big Data cannot be used directly for recommendation system. These data first filter/transform as per requirement. In the paper we discussed filtering techniques and issues related for handling text data. We have implemented recommendation system for movielans dataset, on Hadoop framework and analyzed with different size files. Resultant graph is showing that whenever file size is increasing the execution time is not increasing in the same ratio and we know that data size that are in the form of ratings, ranks, review, feedback are increasing drastically. Here we are proposing Recommendation by applying the weightage of summarized reviews and opinions on the rating of item as future enhancement in this work.
