Read In a POS-Tagged Word Text Document

Return a function which reads in a text document containing POS-tagged words.

Usage

readTagged(...)

Arguments

...: Arguments passed to TaggedTextDocument.

Details

Formally this function is a function generator, i.e., it returns a function (which reads in a text document) with a well-defined signature, but can access passed over arguments (...) via lexical scoping.

Value

A function with the following formals:

elem: a named list with the component content which must hold the document to be read in or the component uri holding a connection object or a character string.
language: a string giving the language.
id: a character giving a unique identifier for the created text document.

The function returns a TaggedTextDocument representing the text and metadata extracted from elem$content or elem$uri. The argument id is used as fallback if elem$uri is null.
