OVERVIEW:
=========

This section goes through a brief overview of the Language Model Creator application. The LM Creator is a GUI that allows the user to draw the word sequences that can be internally converted to Java Speech Grammar Format (JSGF).
And it can generate randomly sentences based on the JSGF file.

The LM Creator tool consists of a main panel and a set of controls that can be assessed via the drop-down menus. The following is a broken down description of the various controls:

MAIN PANEL

The main panel is the rectangular region that allows the user to graphically create a group of nodes. Each node can contain a word list and be selected from under the "Components" menu. The main panel allows the user to layout the structure and order in which the word sequences are via a directed acyclic graph.

File

The file menu contains the following options:

1. New     - This options allow the user to clean the content of the main panel and create new Sof file.
2. Open    - This options allow the user to load existing Sof file.
3. Save    - This options allow the user to save the content of the main panel, i.e., the directed acyclic graph as a Sof file.
4. Save As - This options allow the user to specify a Sof file to save the content of the main panel, i.e., the directed acyclic graph.
5. Quit    - This option quits the current session.

Edit

The edit menu contains the following options:

1. Cut          - This option allows the user to cut a node from the directed acyclic graph, i.e., it deletes the node and copies it to the clipboard.
2. Copy         - This option allows the user to copy a node from the directed acyclic graph, i.e., it copies the node to the clipboard.
3. Paste        - This option allows the user to paste the contents of the clipboard on the main panel where the mouse is located.
4. Insert Arc   - This option allows the user to insert an arc between two nodes.
4. Insert SelfArc   - This option allows the user to insert an loop arc for the node itself.
5. Delete Arc   - This option allows the user to delete an arc between two nodes or delete a self arc.
6. Delete Block - This option allows the user to delete a node from the main panel.

Components

The Components menu contains the following options:

- Start
- Stop
  These options allow the user to plot start/stop node for directed 
  acyclic graph. 

- node
  The option allow the user to plot the node for directed acyclic 
  graph and add/remove word list from the node. 

Utility

The Utility menu contains the following options:

- Convert to JSGF
  The utility can convert the directed acyclic graph to JSGF

- Load Graph
  The utility can load the JSGF and convert it to the directed acyclic graph

- LM Tester
  The utility can randomly generate sentences based on JSGF file
