Sentiment analysis in a multilingual world remains a challenging problem, because developing language-specific sentiment lexicons is an extremely resourceintensive process. Such lexicons remain a scarce resource for most languages. In this paper, we address this lexicon gap by building high-quality sentiment lexicons for 136 major languages. We integrate a variety of linguistic resources to pro...

Temporal taggers are usually developed for a certain language. Besides English, only few languages have been addressed, and only the temporal tagger HeidelTime covers several languages. While this tool was manually extended to these languages, there have been earlier approaches for automatic extensions to a single target language. In this paper, we present an approach to extend HeidelTime to al...

Bilingual dictionaries can be automatically generated using the GIZA++ tool. However, these dictionaries contain a lot of noise, because of which the qualities of outputs of tools relying on the dictionaries are negatively affected. In this work, we present three different methods for cleaning noise from automatically generated bilingual dictionaries: LLR, pivot and transliteration based approa...

1 This paper, which will appear in Harry van der Hulst, Studies on Word Accent, is a second revision (April 2012) of an oral paper presented at the Conference on Word Accent: Theoretical and Typological Issues, University of Connecticut, April 30, 2010. I would like to thank Harry van der Hulst, and two anonymous reviewers for their helpful comments on the earlier drafts. 2 Harry van der Hulst ...

Weighted automata model quantitative aspects of systems like the consumption of resources during executions. Traditionally, the weights are assumed to form the algebraic structure of a semiring, but recently also other weight computations like average have been considered. Here, we investigate quantitative context-free languages over very general weight structures incorporating all semirings, a...

Natural languages1 are among Nature’s most extraordinary phenomena. While humans acquire language naturally and use it with great ease, the formalization of language, which is the focus of research in linguistics, remains evasive. As in other sciences, attempts at formalization involve idealization: ignoring exceptions, defining fragments, and the like. In the second half of the twentieth centu...
