I am a beginner in Computer Science World and SyntaxNet. I wrote a simple SyntaxNet-Python algorithm which used SyntaxNet to analyze a text command a user inserts,"open the file book which I have written with laboratory writer with LibreOffice writer", and then analyzes SyntaxNet output with a python algorithm in order to turn it to an executive command, in this case open a file, with any supported format, with LibreOffice in Linux, Ubuntu 14.04) environment. you can see here the different command lines defined by LibreOffice in order to use different application in this package.
After installing and running SyntaxNet (the installation process in explained here),the shell script is opened demo.sh in ~/models/syntaxnet/suntaxnet/ directory and the conl2tree function (line 54 to 56) is erased in order to get a tab delimited output from SyntaxNet instead of a tree format output.
This command is typed in the terminal window:
echo 'open the file book which I have writtern with the laboratory writer with libreOffice writer' | syntaxnet/demo.sh > output.txt
the output.txt document is saved in the directory where demo.sh exists and it will be somehow like the below figure:
![enter image description here]()
- The
output.txt as the input file and use the below python algorithm to analyze SyntaxNet output and identifies the name of the file you want the target application from LibreOffice package and the command the user wants to use.
#!/bin/sh
import csv
import subprocess
import sys
import os
#get SyntaxNet output as the Python algorithm input file
filename='/home/username/models/syntaxnet/work/output.txt'
#all possible executive commands for opening any file with any format with Libreoffice file

I again say I am a beginner and the code might not seems so tidied up or professional but I just tried to use all my knowledge about this fascinating
SyntaxNet to a practical algorithm.
This simple algorithm can open the file:
with any format which is supported by LibreOffice e.g. .odt,.odf,.ods,.html,.odp.
it can understand implicit reference of different application in LibreOffice, for example: " open the text file book with libreoffice" instead of "open the file book with libreoffice writer"
can overcome the problem of SyntaxNet interpreting the name of the files which are referred as an adjective.
