Introduce
SentiStrength is a tool developed from comments on social networking
sites (MySpace ). Its core function is to use
dictionary-based algorithms to analyse sentiment for text. Specifically,
it first assigns priori sentimental scores to words according to the
sentiment dictionary, and then adjusts the assignation result with
several heuristic rules. It can give a sentimental score pair \((\rho, \eta)\) for each input text, where
\(\rho\) represents the positive score
of the text, and \(\eta\) represents
the negative score. The scale and meaning for \(\rho\) and \(\eta\) are as below:
SentiStrength 是一种根据社交网站(MySpace )上的评论开发的工具。它的核心功能是使用基于字典的算法来分析文本的情感。具体来说,它首先根据情感词典为单词分配先验情感分数,然后使用多种启发式规则调整分配结果。它可以为每个输入文本给出一个情感分数对
\((\rho, \eta)\),其中 \(\rho\) 表示文本的正面分数,\(\eta\) 表示负面分数。\(\rho\) 和 \(\eta\) 的尺度和含义如下:
