Multiple antecedent coreference (MAC) has been largely neglected. This can be explained by the scarcity of the phenomenon of MAC in generic discourse. However, in specialized(More)
This paper presents an implementation of the widely used speech analysis tool Praat as a web application with an extended functionality for feature annotation. In particular, Praat on the Web addresses some of the central limitations of the original Praat tool and provides (i) enhanced visualization of annotations in a dedicated window for feature(More)
Text mining of massive Social Media postings presents interesting challenges for NLP applications due to sparse interpretation contexts, grammatical and orthographical variability as well as its very fragmentary nature. No single methodological approach can be expected to work across such diverse typologies as twitter micro-blogging, customer reviews,(More)
In this paper we present an overview of a UIMA-based system for Sentiment Analysis in hotel customer reviews. It extracts objectopinion/attribute-polarity triples using a variety of UIMA modules, some of which are adapted from freely available open source components and others developed fully in-house. A Solr based graphical interface is used to explore and(More)
