BNS Scaling: An Improved Representation over TF.IDF for SVM Text Classification

HPL-2007-32 (R.1) BNS Scaling: An Improved Representation over TF.IDF for SVM Text Classification - Forman, George
Keyword(s): text classification; topic identification; machine learning; feature selection; Support Vector Machine; TF*IDF text representation
Abstract: In the realm of machine learning for text classification, TF.IDF is the most widely used representation for real-valued feature vectors. Unfortunately, it is oblivious to the training class labels, and naturally scales some features inappropriately. We replace IDF with Bi-Normal Separation (BNS), wh ...

XmTextSetSource(library call)											     XmTextSetSource(library call)

NAME

       XmTextSetSource -- A Text function that sets the source of the widget

SYNOPSIS

       #include <Xm/Text.h>
       void XmTextSetSource(
       Widget widget,
       XmTextSource source,
       XmTextPosition top_character,
       XmTextPosition cursor_position);

DESCRIPTION

       XmTextSetSource	sets  the  source of the Text widget. Text widgets can share sources of text so that editing in one widget is reflected in
       another. This function sets the source of one widget so that it can share the source of another widget.

       Setting a new text source destroys the old text source if no other Text widgets are using that source.  To replace a text source  but  keep
       it for later use, create an unmanaged Text widget and set its source to the text source you want to keep.

       widget	 Specifies the Text widget ID.

       source	 Specifies  the source with which the widget displays text. This can be a value returned by the XmTextGetSource(3) function. If no
		 source is specified, the widget creates a default string source.

       top_character
		 Specifies the position in the text to display at the top of the widget.  This is an integer number of characters from the  begin-
		 ning of the text buffer. The first character position is 0 (zero).

       cursor_position
		 Specifies the position in the text at which the insert cursor is located. This is an integer number of characters from the begin-
		 ning of the text buffer. The first character position is 0 (zero).

       For a complete definition of Text and its associated resources, see XmText(3).
