Elements and Segmentation


[R025] Methods, independent of the semantic, of the elements must exist to provide hints on how to break down document content into meaningful runs of text.


Many applications that process content for linguistic-related tasks need to be able to perform a basic segmentation. They need to be able to do this without knowing about the semantic of the elements. The elements marking up the document content should provide generic clues to help such process.

Two types of information are needed:

1- A way to distinguish elements that may hold text content (a), from elements that never have text content (b).

Example for (a): The element

may hold text:

 <b>This is bold.</b>
 <i>This is italic.</i>

Example for (b): The element
    should not hold text:
     <li>This is the first item.</li>
     <li>This is the second item.</li>

    2- A way to distinguish independent text content that is nested within another content (c), from text content that is part of its parent element's content (d).

    Examples for (c):

    A footnote in DITA: The text in <fn> is distinct from the text of <p>

    <p>Palouse horses<fn callout="#">A Palouse horse is 
    the same as an Appaloosa.</fn> have spotted coats.</p>

    Or, a more complex case: a footnote in OpenDocument:

    <text:p text:style-name="Standard">
     Palouse horses
     <text:note text:id="ftn1" text:note-class="footnote">
       <text:p text:style-name="Footnote">
    A Palouse horse is the same as an Appaloosa.</text:p>
     have spotted coats.</text:p>

    Both examples corresponds to two distinct text runs:

    • Palouse horses have spotted coats.
    • A Palouse horse is the same as an Appaloosa.

    Example for (d): The text in <term> is part of the text of <p>

    <p><term>Palouse horses</term>
    have spotted coats.</p>

    This corresponds to a single text run:

    • Palouse horses have spotted coats.
    A processor should be able to know from a method or infer from the context such information.
