Problems handling Hyperlinks and Tables in Word 97 Docs
-------------------------------------------------------
Key: TIKA-405
URL: https://issues.apache.org/jira/browse/TIKA-405
Project: Tika
Issue Type: Bug
Affects Versions: 0.7
Environment: 32-bit Ubuntu Linux
Reporter: Curtis Warner
I discovered some odd behavior while running a three-way comparison test
between Tika, Aperture, and Autonomy KeyView. The input file was a test Word 97
Doc (attached) including a paragraph peppered with hyperlinks and a table
filled with dummy text. KeyView generated the full text, as I expected.
Aperture and Tika had identical results to one another (barring one lost
whitespace character), but their outputs yielded significantly fewer tokens
than KeyView's did. I've attached the output text from KeyView and Tika for
reference.
There are two distinct problems I recognized in Tika's text output:
1) Hyperlinks from the Word Doc aren't included in the output text. They appear
to have been skipped completely.
2) The values in the Word Doc's table are conglomerated all together into a
single blob rather than being emitted separately, which ruins any attempt at
tokenizing the table's contents.
Seeing as both Tika and Aperture had exactly the same issues with this test
file, my guess is that it's a problem with the shared POI library. I thought it
would be worth noting, though, in case there's an easy fix on the Tika end of
things.
