The PoS Tagger of Turin University

by Leonardo Lesmo
"... parsing system of Turin University. The PoS Tagger is based on a set of disambiguation rules developed manually. The rules are grouped into ambiguity sets, each of which is associated with a set of PoS. Some intra-category rules are defined to assign features to words. The paper includes a brief des ..."

Shallow Parsing with PoS Taggers and Linguistic Features

by Beáta Megyesi, James Hammerton, Miles Osborne, Susan Armstrong, Walter Daelemans - JOURNAL OF MACHINE LEARNING RESEARCH , 2002
"... Three data-driven publicly available part-of-speech taggers are applied to shallow parsing of Swedish texts. The phrase structure is represented by n00 types of phrases in a hierarchical structure containtu labels for every con81E1wN t type the token belongs to in the parse tree. The enw din is base ..."

The Open Source Tagger HunPoS for Swedish

by Beáta B. Megyesi - In Proceedings of the 17th Nordic Conference of Computational Linguistics (NODALIDA , 2009
"... HunPoS, a freely available open source part-of-speech tagger—a reimplementa-tion of one of the best performing taggers, TnT—is applied to Swedish and evaluated when the tagger is trained on various sizes of training data. The tagger’s accuracy is compared to other data-driven taggers for Swedish. Th ..."

CombiTagger: A System for Developing Combined Taggers

by Verena Henrich, Timo Reuter, Hrafn Loftsson - Proceedings of the Twenty-Second International FLAIRS Conference, Sanibel Island , 2009
"... The main task of part-of-speech (PoS) tagging is to as-sign the appropriate morphosyntactic category to each word in a sentence. A combination of different PoS tag-gers usually results in higher tagging accuracy than ob-tained by the use of only a single tagger. We present a new language and tagset ..."

Exploring the human effect on the accuracy of PoS taggers

by Martha Dís Brandt , 2009
"... This paper explores the impact of inconsistencies stemming from human mistakes on the accuracy of part-of-speech (PoS) taggers in Icelandic. It reveals previously unpublished information regarding work on the original corpus that is now used as a gold standard for Icelandic. With this new knowledge ..."

Comparing a Linguistic and a Stochastic Tagger

by Christer Samuelsson, Atro Voutilainen - Proceedings of the Thirty-Fifth Annual Meeting of the Association for Computational Linguistics and Eighth Conference of the European Chapter of the Association for Computational Linguistics , 1997
"... Concerning different approaches to automatic PoS tagging: EngCG-2, a constraintbased morphological tagger, is compared in a double-blind test with a state-of-the-art statistical tagger on a common disambiguation task using a common tag set. The ex- periments show that for the same amount of remainin ..."

Phrasal Parsing by Using Data-Driven PoS Taggers

by Beáta Megyesi, Centre For Speech Technology
"... Three data-driven algorithms are applied to shallow parsing of Swedish texts by using PoS taggers as the basis for parsing. The constituent structure is represented by nine types of phrases in a hierarchical structure containing labels for every constituent type the token belongs to. The results sho ..."

Size is not Everything Genre Balance in Bootstrapping a Swedish PoS Tagger

Extending the View Explorations in Bootstrapping a Swedish PoS Tagger

by Eva Forsbom
"... State-of-the-art statistical part-of-speech taggers mainly use information on tag bi- or trigrams, depending on the size of the train-ing corpus. Some also use lexical emission probabilities above unigrams with benefi-cial results. In both cases, a wider con-text usually gives better accuracy for a ..."
