-----------------------------------------
Summary: Implement Normalized Discounted Cumulative Gain (nDCG) as
an Example
Key: GORA-457
URL: https://issues.apache.org/jira/browse/GORA-457
Project: Apache Gora
Issue Type: Task
Components: gora-tutorial
Reporter: Lewis John McGibbney
Assignee: Lewis John McGibbney
Fix For: 0.8
I have been very interested in the [Normalized Discounted Cumulative
Gain|https://en.wikipedia.org/wiki/Discounted_cumulative_gain] (nDCG) algorithm
for addressing problems within the domain of federated web search. I am very
keen to get a working example/tutorial and implement nDCG within Gora which
would extend the work I did on using Gora as a query broking device.
This issue will implement a tutorial for ... using Gora as a query broker
within a federated search scenario with the emphasis being on utilization of
our FilterList API's.
