Frequency of words

Thu Sep 14 13:08:38 UTC 2017

Besides the command lines that I gave you in my previous email, the other solution is to use "furry [:: fairy]" coding. Notice two ':' characters instead of one. This code will tell MOR command to put the word "furry" on %mor tier instead of the word "fairy". This solution only works if the actual word spoken by a subject is a real word. Otherwise, you will get "?|..." on %mor tier meaning that the word is not recognized. Also, this solution will not ignore the error word as you seem to want to do.

The question is whether you want to simply ignore the [: target] error word, like word "fairy", or do you want to ignore any erroneously spoken words altogether, like the whole "furry [:: fairy]" structure.

If you want to ignore the whole erroneously spoken word, then you need to use one the command lines below depending on whether you want words from speaker tier or lemmas from %mor tier:

freq -sm** -sm@* +sm;fairy +sm;Cinderella +sm;stair Content_Tester.cha

freq -s"<**>" -s"<: *>" +sfairy +sCinderella +sstairs Content_Tester.cha

I have changed you sample file "Content_Tester.cha" by adding word "fairy" that is not an error or a replacement, so you should get 1 "fairy" count in the output of the following two command lines:

We're working with aphasia participants who will often make mistakes, and when they do make mistakes, we'll put in the intended word into [: target] if we know what the intention was. However, I do not want to count [: target] words in the frequency tally of words. Basically, if someone said furry [: fairy] in one instance, and I am looking for a frequency count of the correctly spoken 'fairy,' I want the frequency calculation for 'fairy' to be 0, thus ignoring the word in the target. Further, I'd also like to run for lemmas and not morphological changes. In other words, if I'm looking for "stair," I want 'stairs' to be counted in the frequency of 'stair' usage.

It does do the correct job in tagging 'stair' even though the participant said 'stairs,' a correct usage from the %mor line. Output of frequency for this command was:
>> Cinderella: 1
>> stair: 1
>> fairy: 1

However, it correctly does not look within the [: target] and correctly states that 'fairy' was said 0 times. As an added point, I've also found that when I run the above command on transcripts, it sometimes gets the counts incorrect. For this command, I get the count:
>> Cinderella: 1
>> stair: 0
>> fairy: 0
