PETRARCH

Code for the new Python Engine for Text Resolution And Related Coding Hierarchy (PETRARCH) event data coder. The coder now has all of the functions from the older TABARI coder and the new CAMEO.verbpatterns.140609.txt dictionary incorporates both parser-based matching and extensive synonym sets. The program coded 60,000 AFP sentences from the GigaWord corpus without crashing, using the included dictionaries.

For more information, please visit the (work-in-progress) documentation.

##Installing

It is now possible to install the program. It is highly recommended that you install within a virtual environment. This is alpha software, so things will change moving forward. Seriously, install in a virtual environment.

To install (you're in a virtual environment, right?):

1. Clone the repo

• For example, download the zip file into ~/Downloads.
• This will put the repo into something like ~/Downloads/petrarch.

2. Run pip install -e ~/Downloads/petrarch

This will install the program with a command-line hook. You can now run the program using:

petrarch <COMMAND NAME> [OPTIONS]

You can get more information using:

petrarch -h

StanfordNLP:

If you plan on using StanfordNLP for parsing within the program you will also need to download that program. PETRARCH uses StanfordNLP 3.2.0, which can be obtained from Stanford. PETRARCH's default configuration file assumes that this is unzipped and located in the user's home directory in a directory named stanford-corenlp/, e.g., ~/stanford-corenlp.

The program is stable enough that it is useable, and it is not that likely that there will be large changes in the API.

##Running

Currently, you can run PETRARCH using the following command if installed:

petrarch parse -i <INPUT FILE> -o <OUTPUT FILE>

If not installed:

python petrarch.py parse -i data/text/GigaWord.sample.PETR.xml -o test_output.txt

There's also the option to specify a configuration file using the -c <CONFIG FILE> flag, but the program will default to using PETR_config.ini.

When you run the program, a PETRARCH.log file will be opened in the current working directory. This file will contain general information, e.g., which files are being opened, and error messages.

##Unit tests

Commits should always successfully complete

petrarch validate

This command defaults to the PETR.UnitTest.records.txt file included with the program. Alternative files can be indicated using the -i option. For example (this is equivalent to the default command):

petrarch validate -i data/text/PETR.UnitTest.records.xml

The final record should read

Sentence: FINAL-RECORD [ DEMO ]
ALL OF THE UNIT TESTS WERE CODED CORRECTLY. 
No events should be coded
No events were coded
Events correctly coded in FINAL-RECORD
Exiting: <Stop> record 

##Compatibilities with TABARI dictionaries

PETRARCH has a much richer dictionary syntax than TABARI, and because PETRARCH uses parsed input, many dictionary entries used by TABARI for noun-verb disambiguation are no longer needed. While the initial versions of the program could use existing TABARI dictionaries, PETRARCH-formatted dictionaries are now required: these are available in this repository and in https://github.com/openeventdata/Dictionaries.
