Basic usage script for LabMT1.0 dataset

Project description

labMT-simple
============

TL;DR
a simple labMT usage script


a python module for using the labMT1.0 dataset

no dependencies, unless using the plot function
(then we use matplotlib)

Usage
-----

The Python script test.py uses this module to test a subsample of Twitter data:
```python
## set up
from storyLab import *
labMT,labMTvector,labMTwordList = emotionFileReader(returnVector=True)

## take a look at these guys
print labMT['laughter']
print labMTvector[0:5]
print labMTwordList[0:5]

## test shift a subsample of two twitter days
import codecs ## handle utf8
f = codecs.open("test/01.02.14.txt","r","utf8")
saturday = f.read()
f.close()
f = codecs.open("test/04.02.14.txt","r","utf8")
tuesday = f.read()
f.close()

## compute valence score
saturdayValence = emotion(saturday,labMT)
tuesdayValence = emotion(tuesday,labMT)
print 'the valence of {0} is {1}'.format('saturday',saturdayValence)
print 'the valence of {0} is {1}'.format('tuesday',tuesdayValence)

## compute valence score and return frequency vector for generating wordshift
saturdayValence,saturdayFvec = emotion(saturday,labMT,shift=True,happsList=labMTvector)
tuesdayValence,tuesdayFvec = emotion(tuesday,labMT,shift=True,happsList=labMTvector)

## make a shift: shift(values,ref,comp)
shiftMag,shiftType = shift(labMTvector,saturdayFvec,tuesdayFvec)
## take the absolute value of the shift magnitude
shiftMagAbs = map(abs,shiftMag)

## sort them both
indices = sorted(range(len(shiftMag)), key=shiftMagAbs.__getitem__, reverse=True)
sortedMag = [shiftMag[i] for i in indices]
sortedType = [shiftType[i] for i in indices]
sortedWords = [labMTwordList[i] for i in indices]

## take a peek at the top words
print indices[0:10]
print sortedMag[0:20]
print sortedType[0:20]
print sortedWords[0:20]

## print each of these to a file
f = open("test/sampleSortedMag.csv","w")
for val in sortedMag:
f.write(str(val))
f.write("\n")
f.close()

f = open("test/sampleSortedType.csv","w")
for val in sortedType:
f.write(str(val))
f.write("\n")
f.close()

f = open("test/sampleSortedWords.csv","w")
for val in sortedWords:
f.write(val)
f.write("\n")
f.close()
```
