ICARUS Treebank Manager Perspective:

The perspective is used to create/edit treebanks. Treebanks configured here may be used within the search-perspective.

The latest implementation supports the following input types:

• Tokenized Text
• CoNLL 2009
• CoNLL 2006

• TextCorpusFormat (TCF) 0.4

Treebank Overview: Note the "New Treebank" is marked with an this indicates that there was no location set.

1. Adding a new Treebank using the button. Use modification buttons to delete, rename or edit selected treebank.

2. After clicking the "Add new Treebank Button" the treebank explorer dialog shows up:

   • Name: specify the Treebank Name that will show up in the treebank Overview.
   • Location: treebank location on the file system (local/network).
   • Reader: Reader for the current treebank. E.g.: CONLL09(gold), CONLL09(system) or TCF 0.4.
   • Properties: (currently not used)

3. Use bottun to load the treebank. Afterwards it can be inspected clicking on . The unload button will unload the treebank from the main memory.

Graph-List Outline

This tab is used to show the sentence data when inspecting a treebank :

Graph-List Outline Toolbar:

• = Open the preferences

• = Change the current graph layout. There are three different layout types available

  1. Arc layout

  2. No layout

  3. Tree

• = Clear graph panel - every nodes/edges are deleted

• = Save the current search graph to XML file (may be imported later)

• = Import a search graph XML file

• = Print the current graph

• = Add a new node to the current search graph

• = Connects two nodes (two nodes must be selected before this action can be performed)

• = Connects two nodes with a precedence relation (two nodes must be selected before this action can be performed)

• = Delete selected node/edge (multi selection possible)

• = Open the edit node/edge dialog (Instead of using this button you may doubleclick a node/edge to open the edit dialog)

• = Duplicate (copy and insert) the selected nodes/edges. Quick way to duplicate a graph. Note: edges are only copied when their source and target node is selected.

• = Copy and the selected nodes/edges. Note: edges are only copied when their source and target node is selected. (strg+c)

• = Paste previously copied nodes/edges. (strg+p)

• = Redraw the graph, can be useful while adding new nodes, edges or constraints may mess up the graph layout. Example (arc-layout): (left nodes/edges unsorted; right nodes/edges reorderes)

• = Undo the last graph editor operation

• = Redo the last graph editor operation

• = Increase zoom level

• = Switch back to the default zoom level

• = Decrease zoom level

• = Autofit zoom level to the current graph panel size (default off)

• = Compress graph (right-left). Merge node/edge information into a node. Search annotation highlight is never merged and always visible. (default off)

• = Highlight the incoming edge of the selected node (multiselection possible) (default off)

• = Highlight the outgoing edge/edges of the selected node (multiselection possible) (default off)

  • Example where the node "son" is selected and highlight is switched on for incoming and outgoing edges Note: It is possible to navigate through a graph (after selecting at least one node/edge) using the "arrow keys"

• = unused right now

Treebank Properties Outline

At the very right is the "properties" outline. It consists of two different tabs.

1. Properties: The properties show some additional treebank information. For example, name, status (loaded). Also some Meta-Data is provided that includes the minimum, maximum and average sentence lengt as well as the total length (equal total token count) (

2. Table Outline: A table representation of the graph shown in the Graph-List outline.
