Why do we need a text corpus for NLP?
In the domain of natural language processing ( NLP ), statistical NLP in particular, there’s a need to train the model or algorithm with lots of data. For this purpose, researchers have assembled many text corpora. A common corpus is also useful for benchmarking models.
Is it possible to apply NLP on low resource languages?
While English has many corpora, other natural languages too have their own corpora, though not as extensive as those for English. Using modern techniques, it’s possible to apply NLP on low-resource languages, that is, languages with limited text corpora. What are the traits of a good text corpus or wordlist?
How to clean raw natural language corpus for NLP?
Raw natural language has a number of properties that can muddy analysis down the line. A common first step is to remove stop words; common words that do not offer rich semantic meaning and instead add more noise than signal. Most NLP libraries come with a list of stop words you can utilize to clean your corpus.
What is a corpus?
A corpus can be defined as a collection of text documents. It can be thought as just a bunch of text files in a directory, often alongside many other directories of text files. How it is done? NLTK already defines a list of data paths or directories in nltk.data.path.
