Error message with Regular Expressions in AntConc 4

[tayo olatoye]

Hello Laurence,

I have been using regex to search my pos-tagged corpus in Antconc version 3.5.8 without complaints.  I recently installed Antconc 4.1.1 on my macbook. Then I tried to use some of the regex from my previous queries but I keep getting this error message: >Error creating the database entries. Check that your search query is valid. The error is shown below: user-defined function raised exception.

I installed version 4.0.10 on another windows laptop, and the regex still don't work. But when I use the older version 3.5.8, the search queries work fine.

Here's an example of a recent query: \w+_(VBDR|VBDZ|VBG|VBI|VBM|VBN|VBR|VBZ)\s(\w+_VVN) 

Please kindly advise.

Hi. Just remove the "\s" as regex in AntConc 4 acts at the token level.

Let me know if this works.

Laruence.

Dear Laurence,

Thank you for the response.

No, it doesn't work. I still get the same error message.

Hi again,

Can you try each part separately first, to identify which part is causing the problem?

Laurence.

Dear Laurence,

Your suggestion worked.  I removed the \s and the second (), and the regex below worked:

\w+_(VBDR|VBDZ|VBG|VBI|VBM|VBN|VBR|VBZ) \w+_VVN

Thank you very much.

Kind regards,

Tayo

Excellent! 

As AntConc 4 regex works at the token level, it's not as powerful as in AntConc 3, but I think you'll find that the regex searches are simpler and the results will come back much much faster. I think the only things that regex in AntConc 4 cannot do is look forward and look backward searches.

Laurence.
