Lexicon of Abusive Words
A large lexicon of English abusive words bootstrapped from a small set of manually labeled negative expressions (annotated as either abusive or not-abusive). Currently classifiers based on such lexicons produce by far best results in cross-domain classification.

Sense-level Lexicon of Verbal Shifters
A complete sense-level lexicon of English verbal polarity shifters and their shifting scope. Our lexicon covers all verbs of WordNet v3.1 that are single word or particle verbs. Polarity shifter and scope labels are given for each lemma-synset pair (i.e. each word sense of a lemma).

Annotated Corpus for Disambiguating Verbal Shifters
A gold standard of 2000 labeled sentences where each sentence contains a mention of an ambiguous shifter (e.g. spoil). The sentence label indicates whether the usage of the ambiguous conveys shifting (as in spoil the chances of success) or not (as in spoil a child) in that particular sentence.

A Large Word List of English Verbal Shifters
A list of about 1000 verbal shifters. Shifters, such as abandon, are similar to negations (e.g. not) in that they move the polarity of a phrase towards its inverse, as in abandon all hope. This resource has been bootstrapped from a small base lexicon in which a random sample of 2000 verbs from WordNet have been manually annotated.

German Opinion Role Extractor
This software is designed for the extraction of subjective expressions, sentiment sources and sentiment targets from German text. It has been developed according to the specification of the STEPS Shared Task (see below).

Verb View Lexicon
Resource that classifies all opinion verbs from the English Subjectivity Lexicon and from the German Zurich Sentiment Lexicon according to their sentiment views. Each verb is categorized in one of three view categories. Categories are inspired by the different argument positions an opinion holder can assume. The categories are: agent view, where the opinion holder is realized as the agent of the opinion verb (e.g. love, hate, think), patient view, where the opinion holder is realized as the patient of the opinion verb (e.g. please, disappoint, surprise), and speaker view, where the opinion holder is the implicit speaker of the utterance (e.g. succeed, cheat, lie).
