Getting started

Let's begin with showing how easy it is to find sentiments of Sinhala words using helasentilex

>>> import helasentilex
>>> helasentilex.sentiment('යහපත්')
1
>>> helasentilex.sentiment('අමිහිරි')
-1
>>> helasentilex.sentiment('පරිගණකය')
0

If the input word does not exist in our sentiment lexicon or the input is invalid then it will return None

>>> helasentilex.sentiment(23)
None

You can enter a sentence as a string and get sentiment scores for available words in the sentiment lexicon

>>> helasentilex.sentiments('හොඳින් හෝ නරකින් කරන්න')
{'හොඳින්': 1, 'හෝ': 0, 'නරකින්': -1, 'කරන්න': None}

If the input is invalid then it will return an empty dictionary

>>> helasentilex.sentiments(23)
{}

Defining labels

 1: POSITIVE (ධනාත්මක)
-1: NEGATIVE (ඍණාත්මක)
 0: OBJECTIVE (මධ්‍යස්ථ හෝ උදාසීන)
