Part-of-Speech Tagging of Transcribed Speech
We used four Part-of-Speech taggers, which are available for research purposes and were originally trained on text to tag a corpus of transcribed multiparty spoken dialogues. The assigned tags were then manually corrected. The correction was first used to evaluate the four taggers, then to retrain them. Despite limited resources in time, money and annotators we reached results comparable to tho...
متن کاملIterative Part-of-Speech Tagging
Assigning a category to a given word (tagging) depends on the particular word and on the categories (tags) of neighboring words. A theory that is able to assign tags to a given text can naturally be viewed as a recursive logic program. This article describes how iterative induction, a technique that has been proven powerful in the synthesis of recursive logic programs, has been applied to the t...
متن کاملPart-of-Speech Tagging for Historical English
As more historical texts are digitized, there is interest in applying natural language processing tools to these archives. However, the performance of these tools is often unsatisfactory, due to language change and genre differences. Spelling normalization heuristics are the dominant solution for dealing with historical texts, but this approach fails to account for changes in usage and vocabula...
متن کاملArabic Part of Speech Tagging
Arabic is a morphologically rich language, which presents a challenge for part of speech tagging. In this paper, we compare two novel methods for POS tagging of Arabic without the use of gold standard word segmentation but with the full POS tagset of the Penn Arabic Treebank. The first approach uses complex tags that describe full words and does not require any word segmentation. The second app...
متن کاملSelective Classifiers for Part-of-Speech Tagging
We investigate the use of selective classifiers for part-of-speech tagging (POS). The idea is to allow classifiers to abstain on hard instances, passing them to downstream classifiers that may have more context available. In this report we focus on just the first stage of such a cascade, and ask whether selective classifiers attain the accuracies needed on those instances they accept, given tha...
