Taking into account the inherent inconsistency apparent in the results obtained from {\W}2, we believe to have so far demonstrated results similar to the original findings. We therefore conclude that {\W}2 is a promising system currently being hampered by several issues:

\bi
\item
Inconsistency in results.
\item
Lack of error protection.
\item
Lack of understanding as to how {\W}2 scales to larger amounts of historical data.
\item
Lack of understanding as to how {\W}2 performs with other types of data.
\item
Somewhat confusing codebase makes for difficult maintenance.
\ei

With the above issues in mind, we identify several areas that warrant further exploration as part of ongoing {\W}2 research:

\bi
\item	
Best/Rest set sizes and their effects on results.
\item
Optimum best/rest set sizes.
\item
Effect dataset type has on results.
\item
Larger datasets.
