## Examples
|
|
|
|
Example use (single string):
|
|
|
|
```python
|
|
>>> from sentistrength import PySentiStr
|
|
>>> senti = PySentiStr()
|
|
>>> result = senti.getSentiment('What a lovely day')
|
|
>>> print(result)
|
|
|
|
... [0.25]
|
|
```
|
|
|
|
|
|
Example use (list of strings or pandas Series):
|
|
|
|
```python
|
|
>>> from sentistrength import PySentiStr
|
|
>>> senti = PySentiStr()
|
|
>>> str_arr = ['What a lovely day', 'What a bad day']
|
|
>>> result = senti.getSentiment(str_arr, score='scale')
|
|
>>> print(result)
|
|
|
|
... [0.25,-0.25]
|
|
# OR, if you want dual scoring (a score each for positive rating and negative rating)
|
|
>>> result = senti.getSentiment(str_arr, score='dual')
|
|
>>> print(result)
|
|
|
|
... [(2, -1), (1, -2)]
|
|
# OR, if you want binary scoring (1 for positive sentence, -1 for negative sentence)
|
|
>>> result = senti.getSentiment(str_arr, score='binary')
|
|
>>> print(result)
|
|
|
|
... [1, -1]
|
|
# OR, if you want trinary scoring (a score each for positive rating, negative rating and neutral rating)
|
|
>>> result = senti.getSentiment(str_arr, score='trinary')
|
|
>>> print(result)
|
|
|
|
... [(2, -1, 1), (1, -2, -1)]
|
|
```
|
|
|
|
## Path Setup
|
|

|
Specify the paths as such:
|
|
|
|
```python
|
|
>>> senti = PySentiStr()
|
|
>>> senti.setSentiStrengthPath = ... # e.g. 'C:/Documents/SentiStrength.jar'
|
|
>>> senti.setSentiStrengthLanguageFolderPath = ... # e.g. 'C:/Documents/SentiStrengthData/'
