opinion mining deals with an analysis of user reviews for extracting their opinions, sentiments and demands in a specific area, which can play an important role in making major decisions in such area. in general, opinion mining extracts user reviews at three levels of document, sentence and feature. opinion mining at the feature level is taken into consideration more than the other two levels d...

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...

This paper deals with morphological and part-of-speech tagging applied to manuscripts written in Middle High German. I present the results of a set of experiments that involve different levels of token normalization and dialect-specific subcorpora. As expected, tagging with “normalized”, quasi-standardized tokens performs best. Normalization improves accuracies by .–. percentage points, r...

This paper focuses on the task of tagging text with their parts of speech. The methodology chosen for this task is the Maximum Entropy based Model and although complex will only be explained briefly. More importantly, the focus will center on the differences in performance of the maxent model with varying feature sets compared to the baseline model. One problem highlighted in part-of-speech tag...

The electronic learner corpus of student texts in German, the PACT, contains parts-of-speech (POS) tagging. This markup is performed automatically using RFTagger. Since are written by students, they may contain various kinds errors: grammatical, spelling, stylistic, and others. Sentences be formulated incorrectly, without taking into account rules language accepted norms. can affect work progra...

Parts of speech tagging is a well-understood problem in NLP. The importance of the problem focuses from the fact that the Parts of Speech tagging is one of the first stages in the process performed by various natural language related process. POS tagging is the process of assigning the part of speech tag or other lexical class marker to each and every word in a sentence. POS tagging has a cruci...
