How to solve the errors when I run SPADE

Question

I run the SPADE package and I referenced the Charniak Parser according to the documentation and edited spade.pl for the $CHP variable, but it did not work. It still throws an exception as follows

sh: 1: /home/khaing/Downloads/CharniakParser/parseIt: not found
system /home/khaing/Downloads/CharniakParser/parseIt -LEn /home/khaing/Downloads/CharniakParser/DATA/ /home/khaing/Documents/test.txt > /home/khaing/Documents/test.txt.chp failed: 32512 at /home/khaing/Downloads/SPADE/bin/spade.pl line 38.

The exception is that parseIt is not found. When I review the Charniak Parser, it has five folders: CVS , ecstuff , DATA , TRAIN and PARSE . I did not see parseIt . But I found pareIt.c in PARSE folder so I edited the path CharniakParser/PARSE/parseIt but it still has errors.

Answer 1

The instructions that you link to say

Edit spade.pl in the bin/ directory; set the value for the $CHP variable to the directory path for Charniak's parser

So if SPADE cannot find parseIt then you have set $CHP to the wrong path.

If there is no parseIt binary but you have parseIt.c then I would guess that you have to build it. Check the documentation for the Charniak Parser

Answer 2

Here are concrete steps to obtain the latest version of the Charniak parser and build it:

1. Make a directory where you'll install the parser: (where /path/to is the directory you'd like to put the parser in -- maybe /home/Khaing in your case)

    shell% mkdir /path/to/bllip-parser shell% cd /path/to/bllip-parser/ 

2. Download and extract the latest version of the Charniak Parser:

    shell% wget https://github.com/BLLIP/bllip-parser/archive/master.zip shell% unzip master.zip shell% mv bllip-parser-master/* bllip-parser-master/.* . shell% rmdir bllip-parser-master 

3. Build the parser:

    shell% make PARSE 

4. Confirm that parseIt was built correctly:

    shell% ls first-stage/PARSE/parseIt first-stage/PARSE/parseIt 

   If you run first-stage/PARSE/parseIt you should see its help menu.

5. At this point, you can set $CHP to point inside the bllip-parser directory you made in step 1: Change $CHP in spade.pl to /path/to/bllip-parser/first-stage/PARSE/
