This course will cover concepts in natural language processing (NLP). Developers will find this valuable because of the high demand for NLP skills. This includes understanding natural language when building applications like chatbots, sentiment analysis, search engines, and content recommendations. NLP also provides tools for data analysis, personalization, and content filtering.

In this course, you will learn concepts of NLP, how to use the tm package, the use of corpora, how to convert text to structured data, advanced search techniques, metadata, and how to use quanteda, and tidytext.

With this information, you can expect to command in-demand skills in many text-processing-related fields.

newCorpus <- Corpus(DirSource(directory = "./Muhammad_Iqbal/"))

newCorpus <- Corpus(directory = "./Muhammad_Iqbal/")

newCorpus <- Corpus(FileSource(directory = "./Muhammad_Iqbal/"))

newCorpus <- DirSource(directory = "./Muhammad_Iqbal/")

Which option creates a corpus without errors?

Which option creates a corpus without errors?

Which two columns in a data frame are expected by `DataframeSource`?

Which two columns in a data frame are expected by <code>DataframeSource</code>?

`Corpus(ZipSource("./Muhammad_Iqbal/Archive.zip,"
                 recursive = TRUE)`


`Corpus(ZipSource("./Muhammad_Iqbal/Archive.zip",
                 directories = TRUE)`

`Corpus(ZipSource("./Muhammad_Iqbal/Archive.zip")`

`ZipCorpus("./Muhammad_Iqbal/Archive.zip",recursive = TRUE)`

Which code will create a corpus from the contents of a ZIP archive, including all directories in the archive?

Which code will create a corpus from the contents of a ZIP archive, including all directories in the archive?

The source must be either `DataframeSource`, `DirSource`, or `VectorSource`.

The documents imported must be text contained in a `data.frame` or in a vector.

The source must be `URISource`, `XMLSource`, or `ZipSource`.

`newSimpleCorpus <- SimpleCorpus(
 ZipSource("./Muhammad_Iqbal/Archive.zip")`

**(Select all that apply.)** Under which conditions will `Corpus` produce a `SimpleCorpus`?

(Select all that apply.) Under which conditions will <code>Corpus</code> produce a <code>SimpleCorpus</code>?
