kRp.text-class function

S4 Class kRp.text

This class is used for objects that are returned by treetag or tokenize. class

Slots

• lang: A character string, naming the language that is assumed for the tokenized text in this object.

• desc: Descriptive statistics of the tagged text.

• tokens: Results of the called tokenizer and POS tagger. The data.frame usually has eleven columns:

   - **`doc_id`:**: Factor, optional document identifier.
   - **`token`:**: Character, the tokenized text.
   - **`tag`:**: Factor, POS tags for each token.
   - **`lemma`:**: Character, lemma for each token.
   - **`lttr`:**: Integer, number of letters.
   - **`wclass`:**: Factor, word class.
   - **`desc`:**: Factor, a short description of the POS tag.
   - **`stop`:**: Logical, `TRUE` if token is a stopword.
   - **`stem`:**: Character, stemmed token.
   - **`idx`:**: Integer, index number of token in this document.
   - **`sntc`:**: Integer, number of sentence in this document.
   
   This data.frame structure adheres to the "Text Interchange Formats" guidelines set out by rOpenSci[1].
  

• features: A named logical vector, indicating which features are available in this object's feat_list slot. Common features are listed in the description of the feat_list slot.

• feat_list: A named list with optional analysis results or other content as used by the defined features:

    * `hyphen`A named list of objects of class `kRp.hyphen`.
    * `readability`A named list of objects of class `kRp.readability`.
    * `lex_div`A named list of objects of class `kRp.TTR`.
    * `freq`A list with additional results of `freq.analysis`.
    * `corp_freq`An object of class `kRp.corp.freq`, e.g., results of a call to `read.corp.custom`.
    * `diff`Additional results of calls to a method like `textTransform`.
    * `doc_term_matrix`A sparse document-term matrix, as produced by `docTermMatrix`.
   
   See the `getter and setter methods` for easy access to these sub-slots. There can actually be any number of additional features, the above is just a list of those already defined by this package.
  

Note

There is also as() methods to transform objects from other koRpus classes into kRp.text.

Contructor function

Should you need to manually generate objects of this class (which should rarely be the case), the contructor function kRp_text(...) can be used instead of new("kRp.text", ...).
