Computational Methods for Corpus Annotation and Analysis by Xiaofei Lu

By Xiaofei Lu

In the earlier few a long time using more and more huge textual content corpora has grown speedily in language and linguistics study. This used to be enabled through extraordinary strides in usual language processing (NLP) expertise, know-how that permits desktops to instantly and successfully technique, annotate and study quite a lot of spoken and written textual content in linguistically and/or pragmatically significant methods. It has turn into more advantageous than ever prior to for language and linguistics researchers who use corpora of their study to achieve an enough knowing of the suitable NLP expertise to take complete good thing about its capabilities.
This quantity presents language and linguistics researchers with an obtainable creation to the cutting-edge NLP expertise that enables computerized annotation and research of enormous textual content corpora at either shallow and deep linguistic degrees. The ebook covers a variety of computational instruments for lexical, syntactic, semantic, pragmatic and discourse research, including targeted directions on tips on how to receive, set up and use every one device in numerous working platforms and structures. The ebook illustrates how NLP know-how has been utilized in contemporary corpus-based language stories and indicates potent how you can larger combine such know-how in destiny corpus linguistics research.
This publication presents language and linguistics researchers with a worthwhile reference for corpus annotation and analysis.

Sample text

This can be achieved via pipes and will allow us to perform fairly complex tasks. txt. txt but without the part-of-speech field. Before we introduce pipes, let us look at how this can be done by taking a series of steps one after another. Since the output of each step becomes the input of the following step, we will redirect the output of each step to a new file. txt to lowercase. txt. You can, however, skip this step if you do not think that capitalization should be ignored. txt¶ this is a sample file.

The word Google when it first appeared in written text). Whereas we will not worry about the details of how POS tagging algorithms deal with these issues here, we note in passing that they typically make use of multiple sources of information for inferring the POS categories of ambiguous or out-of-vocabulary words, including contextual information and morphological information, among others. Once the POS categories of the tokens in the text have been determined, the POS tagger applies a label to each token.

The second example below prints all three fields with the order of the second field and the third field switched.
