This article outlines the recently used methods for designing part-of-speech taggers; computer programs for assigning contextually appropriate grammatical descriptors to words in texts. It begins with the description of general architecture and task setting. It gives an overview of the history of tagging and describes the central approaches to tagging.

Part of speech tagging for Arabic
Natural Language Engineering, 2011AbstractThis paper presents an investigation of part of speech (POS) tagging for Arabic as it occurs naturally, i.e. unvocalized text (without diacritics). We also do not assume any prior tokenization, although this was used previously as a basis for POS tagging. Arabic is a morphologically complex language, i.e.

One of the fundamental tasks in natural-language processing is the morpho-lexical disambiguation of words occurring in text. Over the last twenty years or so, approaches to part-of-speech tagging based on machine learning techniques have been developed or ported to provide high-accuracy morpho-lexical annotation for an increasing number of languages ...

WIREs Computational Statistics, 2011
AbstractPresented here is a brief state‐of‐the‐art account on part‐of‐speech (POS) tagging. POS tagging is an essential preprocessing task for many natural language processing goals and applications. Some POS tagging approaches make use of annotated corpora to train computational models to perform the task with minimal human intervention.

Corpus based part-of-speech tagging
International Journal of Speech Technology, 2016In natural language processing, a crucial subsystem in a wide range of applications is a part-of-speech (POS) tagger, which labels (or classifies) unannotated words of natural language with POS labels corresponding to categories such as noun, verb or adjective.

Part-of-Speech Tagging Using Evolutionary Computation
Studies in Computational Intelligence, 2014Part-of-speech tagging is a task of considerable importance in the field of natural language processing. Its purpose is to automatically tag the words of a text with labels that designate the appropriate parts-of-speech. The approach proposed in this paper divides the problem into two tasks: a learning task and an optimization task. Algorithms from the

Part-of-speech tagging for portuguese texts
1995In this paper we will describe the work that is being cooperatively done by Portugal and Brazil. It uses Statistical Methods for Natural Language Processing. Namely, we will focus on the problem of Part-of-Speech (POS) Tagging. POS Tagging is a recent and successful technique for assigning each word in a sentence its correct POS tag. This technique can

Part of Speech Tagging for Romanian Text-to-Speech System
2011 13th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing, 2011This paper describes a Part of Speech (POS) tagger that has been developed for Romanian Text-to-Speech purposes. In our Text-to-Speech (TTS) system, the Part of Speech tagger is used to disambiguate the pronunciation of some homograph words, determine the semantic links between words, phrase breaks and intonation phrase boundaries and eventually design

Part-of-Speech Tagging by Latent Analogy
IEEE Journal of Selected Topics in Signal Processing, 2010Part-of-speech tagging is often a critical first step in various speech and language processing tasks. High-accuracy taggers (e.g., based on conditional random fields) rely on well chosen feature functions to ensure that important characteristics of the empirical training distribution are reflected in the trained model.
