In tm.plugin.lexisnexis: Import Articles from 'LexisNexis' Using the 'tm' Text Mining Framework

Description

This package provides a tm Source to create corpora from articles exported from the LexisNexis content provider as HTML files.

Details

Typical usage is to create a corpus from HTML files exported from LexisNexis (here called myLexisNexisArticles.html). Setting language=NA allows the language to be set automatically from the information provided by Factiva:

    # Import corpus
    source <- LexisNexisSource("myLexisNexisArticles.html")
    corpus <- Corpus(source, readerControl = list(language = NA))

    # See how many articles were imported
    corpus

    # See the contents of the first article and its meta-data
    inspect(corpus[1])
    meta(corpus[[1]])
  

Currently, only HTML files saved in English and French are supported. Please send the maintainer examples of LexisNexis files in your language if you want it to be supported.

See link{LexisNexisSource} for more details and real examples.
