Allan commented on PIG-2353:
----------------------------
Dear all,
Let me introduce myself, I am Allan Avendaño, student of Master Computing
Engineering at Rome. I am interested into collaborate with Rank function like
SQL [#PIG-2353] for Gsoc.
I have been working with MR paradigm since three years, mainly with two
research projects (which were part of undergraduate projects).
One was aimed to analyze the incidence of navigability factors on websites
university network, by creating a inverse correlation among them through links
and citations.
My undergraduate project was driven to solve the previous navigability problem,
by establishing relations among them according to terms used and topics. Was
really interesting to interleave some MR phases (some modifications to Mahout
code) and Pig.
I was checking the activities of this feature, and also an initial approach at
[#PIG-821], I think also could be useful dense rank an nth-tile, and other
statistical inference operations.
Really thankful for your guidance and comments.
Best Regards
