Overview

A key challenge of identifying sentiment in user-generated content is informal language use, since sentiment is often expressed by slang words. In order to tackle the challenge, we built and release a large scale sentiment lexicon of slang words, SlangSD, which contains over 90,000 slang words/phrases. SlangSD can be useful for research related to analyzing sentiment on social media platforms. The slang words are obtained from UrbanDictionary. The annotation of sentiment polarity is automatically conducted with the help of existing sentiment lexicons, content from Twitter, and the synonym feature of UrbanDictionary. A detailed introduction of how we built SlangSD, and preliminary results of leveraging it on sentiment analysis can be found here.

In the data files, each row corresponds to a slang word-sentiment polarity pair. The first column is a lowercased slang word, and the second column is the corresponding sentiment polarity. The two columns are split by a tab character ('\t').

Below are two rows from the lexicon:

==============================================

perpindiculous -2

slap it fresh 1

==============================================

The sentiment polarity takes 5 values: -2 (strongly negative), -1 (negative), 0 (neutral), 1 (positive), and 2 (strongly positive).
