list_lexicons: Built-in lexicons

In sentometrics: An Integrated Framework for Textual Sentiment Time Series Aggregation and Prediction

Description

A list containing all built-in lexicons as a data.table with two columns: a x column with the words, and a y column with the polarities. The list element names incorporate consecutively the name and language (based on the two-letter ISO code convention as in stopwords), and "_tr" as suffix if the lexicon is translated. The translation was done via Microsoft Translator through Microsoft Word. Only the entries that conform to the original language entry after retranslation, and those that have actually been translated, are kept. The last condition is assumed to be fulfilled when the translation differs from the original entry. All words are unigrams and in lowercase. The built-in lexicons are the following:

• FEEL_en_tr

• FEEL_fr (Abdaoui, Azé, Bringay and Poncelet, 2017)

• FEEL_nl_tr

• GI_en (General Inquirer, i.e. Harvard IV-4 combined with Laswell)

• GI_fr_tr

• GI_nl_tr

• HENRY_en (Henry, 2008)

• HENRY_fr_tr

• HENRY_nl_tr

• LM_en (Loughran and McDonald, 2011)

• LM_fr_tr

• LM_nl_tr

Other useful lexicons can be found in the lexicon package, more specifically the datasets preceded by hash_sentiment_.
