TexNet32 - Recent Updates
The URL used to access online help if HTML Help does not work
has been changed.
The package has been recompiled
under Borland's free (100-year license) Delphi 2006 for Win32 Explorer.
Negative and positive weighting on selected stems
has been changed to make use of the appropriate parameters.
Proximity operators are now allowed
in queries for the Boolean extract option.
New scripting commands have been added
for the various kinds of extraction,
and for opening a full text file,
saving an extract,
and running a script.
Workarounds have been added
for some bugs in newer versions of the Rich Edit control:
one in the text replacement function,
which caused hanging
during conversion of TexNetF .DOC files,
and a second that would cause unwanted coloring of the text;
another in the text color settings,
which sometimes caused incorrect coloring
of text filtered from HTML.
Highlighting of keywords or positive or negative cue words
is now done in the linking assistance subwindow,
rather than using a transparent overlay
that brought out some buggy behavior in the Rich Edit control.
An obscure bug whereby,
if the VisualSpeller ActiveX control could not be initialized,
a series of access violation messages would appear
has been eliminated
by setting the idle event handler later in initializing the application.
Meta-tagged keywords can now be imported from an HTML file.
Highlighting from an editing window
now no longer shows through
onto other dialogs and windows.
Some minor improvements have been made to the 2-d graphic display:
axes now pass through the origin,
and the Y-axis title is displayed in 90° rotation
and may be up to 60 characters.
Menu items are now available
to select the current paragraph and the current word.
Scripts may now be run
to set parameters and weight paragraphs.
Automatic running of a startup script
is available as an option.
Parameter settings and the latest weighting sequence
may be saved as scripts.
Fonts, alignment, bulleting, indentations, and tabs
may now be selected
when editing Rich Text.
Highlighting of key words is now accomplished
with an overlay;
this is much quicker than the previous method
and does not interfere with text formatting.
An option is available to cancel highlighting.
The user may now choose to paste either plain text
or Rich Text.
A problem with compaction options for text in graphic displays,
introduced because of a misleading compiler warning,
has now been eliminated.
The application has been ported to Delphi Professional version 6.
One adverse effect of this is that the application file is now much larger.
On the other hand,
the downloadable file is smaller,
because it has also been necessary to drop the HTML viewer,
which is no longer supported by Delphi.
In place of the HTML viewer,
a function has been added to allow import via a URL.
can now be exported to VRML files.
The ancillary list, paragraph weights, parameters,
and words in full text windows
are now normal windows
and do not appear within the main window.
A "Reform" function has been added
in the "Edit" menu
to strip extra spaces and ends of lines
from text copied and pasted from HTML viewers.
Two- and three-dimensional displays
of term associations
are now available through the "Tools" menu.
Terms can be assigned two- or three-dimensional coordinates automatically
from cooccurrence data.
A "Graph coocurring words" function
in the "Other" menu
allows term cooccurrence data to be saved to a file
and provides a graphic display of word cooccurrences.
A "Sentences" function
now available in the "Extract" menu
provides a list of sentences
ranked by a score combining density of frequent keywords and positive cues
and rarity of negative and cohesion cues.
