Learning from Within? Comparing PoS Tagging Approaches for Historical Text
In this paper, we investigate unsupervised and semi-supervised methods for part-of-speech (PoS) tagging in the context of historical German text. We locate our research in the context of Digital Humanities where the non-canonical nature of text causes issues facing an Natural Language Processing world in which tools are mainly trained on standard data. Data deviating from the norm requires tool...
متن کاملComparison of Unigram, Bigram, HMM and Brill’s POS Tagging Approaches for some South Asian Languages
Part-of-Speech (POS) Tagging is a process that attaches each word in a sentence with a suitable tag from a given set of tags. POS Tagging is important in various areas of Natural Language Processing. Different methods of automating the process have been developed and employed for English and other Western languages. Some similar work, most of which utilize the stochastic approaches for POS Tagg...
متن کاملAn improved joint model: POS tagging and dependency parsing
Dependency parsing is a way of syntactic parsing and a natural language that automatically analyzes the dependency structure of sentences, and the input for each sentence creates a dependency graph. Part-Of-Speech (POS) tagging is a prerequisite for dependency parsing. Generally, dependency parsers do the POS tagging task along with dependency parsing in a pipeline mode. Unfortunately, in pipel...
متن کاملSimple Semi-Supervised POS Tagging
We tackle the question: how much supervision is needed to achieve state-of-the-art performance in part-of-speech (POS) tagging, if we leverage lexical representations given by the model of Brown et al. (1992)? It has become a standard practice to use automatically induced “Brown clusters” in place of POS tags. We claim that the underlying sequence model for these clusters is particularly well-s...
متن کاملPOS Tagging Using Relaxation Labelling
Relaxation labelling is an optimization technique used in many fields to solve constraint satisfael,ion problems. The algorithm finds a combination of values for a set of variables such that satisfies to the maximum possible degree-a set of given constraints. This paper describes some experiments performed applying it to POS tagging, and the results obtained, it also ponders the possibility of ...
