%gra and %mor tiers

[Simge Topaloglu]

Hello,

I am trying to extract instances where the conjunction 'and' connects elements of the same syntactic category that form a constituent together, e.g., complex subjects like "John and Mary" as in "John and Mary like apples" or complex objects as in "John likes apples and pears" or - though I know this is presumably trickier - VPs as in "John likes apples and hates pears."

The first code I tried for an approximation of what I wanted was combo +d7 +sg|SUBJ^g|CONJ^g|COORD +t%mor +t%gra.

This found all subjects immediately followed by a conjunction immediately followed by the element that was conjoined with this subject. But as you will notice, there are things this code doesn't get. For example, I am only interested in and, but this code finds other conjunctions like or as well. I tried to incorporate this information into the code using the %mor tier (coord|and), but I think I made a mistake because I got a blank output. Also, while I can make this code work for subjects and objects, I don't know how I will extract cases of VP-level conjunction, because the heads of the conjoined phrases (the verbs) will not necessarily be adjacent. 

Any help for solving these problems would be much appreciated.

Thank you so much,

Simge

Hi Simge,

You can use this command to make sure that only word “and” is found:

combo +d7 +sg|SUBJ^m;and^g|COORD

Hi Leonid,

Thank you so much, but I don't think this code works. It doesn't detect anything, and I get the message "Strings matched 0 times" for all files. I think the code needs to be modified, but I don't know how.

Simge,

The code I gave you below is looking for SUBJ followed by word "and" followed by COORD. This sequence is a modified copy of your command line. I just replaced CONJ with more specific word "and". I don't know what sequences you are looking for, nor do I know what your data looks like, so I can't be more precise with my suggestions. To learn more about syntax of +sm or +sg type command "freq +sm" or "freq +sg" in CLAN or read about it in CLAN manual.

Also, my suggested command lines are tested with the latest version of CLAN and the latest MOR grammar only. If you have an older version of CLAN or your data was created with older versions of MOR grammar, then those commands might not work.

Leonid.

Hi Leonid,

Thanks so much for the heads-up. Indeed, the problem seems to have been CLAN. I had an earlier version (released in 2018), so I just downloaded and installed the latest version and the code worked. 

Thank you so much!!!

Best wishes,

Simge
