Option Panel


The options panel contains 4 tabs: search, history, display options and semantic network.

Search Panel

You can use the search panel to select a new focus concept. By default, it searches for strings starting with the given text. You can also search for concepts which have the search term anywhere in them by selecting the second radio button. The third button is used for an exact search. The fourth button allows you to use the NAT Expression Search which is similar to Regular Expressions and allows you to do a more advanced search.

Here are the tokens which NATEx accepts with their meanings.

Examples

History Panel

Here you can see the history of concepts you have viewed. You can also enable a recovery feature, save your current history, or load a previously saved history. You can also use previous and next to the same effect as the forward and back buttons in the focus concept panel.

 

Display Options

The “Display concept definition” option toggles whether the definition panel, displayed on the bottom, will be shown.

“Display concept sources” determines whether the sources for each concept (in green text) will be shown and whether they will be displayed in abbreviated or full form.

The “Display concept unique identifiers” box allows you to remove the (red) concept unique identifiers shown by default.

“Display concept semantic types” allows you to toggle whether the semantic type for each concept (shown in blue text) will be displayed.

“Display self loops” allows you to toggle whether or not self loops are displayed in the parents/children panels. For example, if you search for Fever, turn on show grandparents, and do a filter for fever, you can see several self-loops are displayed. For example, Fever itself is listed as both a Grandparent and a Parent of Fever. If you uncheck the “Display self loops” box though, it removes those loops within the parents panel. Note, however, that the longer loop of Fever as a grandparent of the focus concept Fever will be left there.

The “Show Unselected Sources warning” option will alert you if you try to bring up a concept which is not in the list of selected sources but is included in one which you currently have unselected.

The “Tooltips” option allows you to toggle whether tool tips are shown when you hover over a concept, and also, whether the tool tip will display information about the concept, or the semantic type.
