Subject RE: [VOTE] Apache Tika 1.11 Release Candidate #1
Date Wed, 21 Oct 2015 13:42:40 GMT
+0 (some regressions in ppt content)

I just finished the batch comparison run on  ~1.8 million files in our govdocs1 and commoncrawl
corpora comparing Tika 1.10 to 1.11-rc1.  As a caveat, the eval code is still in development
and there may be bugs in the reports.

Results are here: https://github.com/tballison/share/blob/master/tika_comparisons/tika_1_10_vs_1_11-rc1.zip

Key reports:
contents/content_diffs.csv (file had one corrupt row when viewing in Excel...manually deleted
offending content)
exceptions/newExceptionsInBByMimeTypeByStackTrace.csv (small handful)
exceptions/fixedExceptionsInBByMimeType.csv  (none!)

On the positive side:
From "mime_diffs_A_to_B.csv", it looks like we are catching more pdfs as pdfs (that text/xhtml)
than we were...great!  We're identifying more files as images (jpeg, pict) than as xhtml,
and, from a quick look, this appears to be an improvement.  We have at least 9 new x-hwp-v5

On the negative side:

1) We have a few regressions in ppt exceptions (six of the same aioobe).
2) We have regressions in ppt content (it looks like we're not adding a new line/word break
where we need to).  The regressions are small per file, but they affect ~220 ppts out of ~1500

Other than the regressions in ppt content, I'd be +1, but I don't think this is severe enough
to warrant a re-spin.  Happy to look into a fix, though, if we want a re-spin...and even if
we don't, I'll start looking into this asap.
