[jira] Commented: (TIKA-405) Problems handling Hyperlinks and Tables in Word 97 Docs

["Nick Burch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12864392#action_12864392 ] 

Nick Burch commented on TIKA-405:
---------------------------------

HWPF (the POI component that handles .doc files) is in need of a bit of love - the main developer of the component left some time ago, and no new champion has taken it up again...

I would suggest opening a new bug against poi. To that, I'd suggest adding a few very simple .doc files, something like:
* 2 paragraphs of text
* 2 paragraphs of text, which contains some hyperlinks
* 2 paragraphs of text, separated by a simple table

You might then want to look at seeing how the files differ, and how HWPF sees them differing, then contribute a patch to hwpf.extractor.WordExtractor :)

> 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.
