DSLRAE is a hierarchical classifier for similar written languages and varieties based on maximum-entropy (maxent) classifiers. In the first level, the text is classified into a language group using a simple token-based maxent classifier. At the second level, a group-specific maxent classifier is applied to classify the text as one of the languages or varieties within the previously identified group. For each group of languages, the classifier uses a different kind and combination of knowledge-poor features: token or character n-grams and 'white lists' of tokens. Features were selected according to the results of applying ten-fold cross-validation over the training dataset. The system presented in this article 1 has been ranked second in the Discriminating Similar Language (DSL) shared task co-located within the VarDial Workshop at COLING 2014 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
