Browsing a Dictionary Hierarchy

This section provides tips and strategies for browsing through data in the Terminology Data Tree Structure window. You can start a browsing session in the following ways:

• In the Exploration tab, click Hierarchies, then choose a Language and Dictionary to explore. This strategy starts a browsing session at the top level of a dictionary.

  You can only browse the top level of a dictionary if that dictionary is eligible for autoquery. For instructions on checking if a dictionary is eligible, see Autoquerying Dictionaries.

• Perform a Terminology Search or Verbatim Term Search, choose a term, expand its Details node, then click the Term Hierarchy link. The Terminology Data Tree Structure window will open and display the selected term in focus.

This section discusses the following Actions you can take in the Terminology Data Tree Structure window:

• Introduction to Browsing the Dictionary Hierarchy
  
• Starting a Browsing Session from the Hierarchies Link
  
• Browsing in the Terminology Data Tree Structure
  
• Expanding a Branch One Level Using the Arrow Keys
  
• Expanding a Branch in the Dictionary
  
• Reversing the Orientation of the Tree Window
  
• Launching the Term Details Window
  

Introduction to Browsing the Dictionary Hierarchy

The example in Figure 14-9 shows the Terminology Data Tree Structure interface for selected terms in a strong dictionary, MedDRA Primary Path.

Example 14-3 Explanations of Annotations in Figure 14-9

1. In order to set the focus on a term, click on the row that contains it or use the Ctrl key to select the respective row.
2. The arrow button expands or contracts a single branch of the tree. In this example, "Vascular disorders", "Vascular injuries" and "Vascular injury" are expanded, while "Venous and vena caval injuries" are contracted.
3. The Term Name of each record is hyperlinked to the Term Details page.
4. Clicking the reverse button switches the orientation of the Tree Structure window. If the tree structure is organized to display the child terms of the in-focus term (the one on the highlighted row), you can reverse direction to see the parent terms of any term you select in the window.

There are also three more buttons that you can use, located on the table header:

• When you have a term highlighted on a row, click this button: to go up one level in the tree structure.
• To go to the top of the structure, click this button: .
• When you want to explore a multi-layered structured, you can choose to see the highlighted term as the first row in the table by clicking this button: . If you wish to go back to the previous view, click the blue arrow that will appear next to the term to have an overall view of the structure and choose the desired level of detail:

Starting a Browsing Session from the Hierarchies Link

Clicking the Hierarchies link on the Exploration tab enables you to start browsing a dictionary's data from its top level. To start browsing the top level of a dictionary:

1. From the Exploration tab, click Hierarchies. The Hierarchy page opens.
2. If the Language list appears, choose the language of the dictionary you want to browse. The Terminology list populates with dictionaries in that language.

   The Language list is not included when all accessible dictionaries in the database are in the same language.

3. Choose a dictionary from the Terminology list, and click Search. The TMS Lite Browser launches the Terminology Data Tree Structure; see Browsing in the Terminology Data Tree Structure.

Browsing in the Terminology Data Tree Structure

When you browse dictionary hierarchy, the Terminology Data Tree Structure window loads all of the terms from that dictionary's highest level. Figure 14-10 displays part of the tree from a session browsing the top level of the MedDRA Primary Path Dictionary.

Figure 14-12 Figure 14-10 Several Records in the Terminology Data Tree Structure

Each of the rows in this example are terms on the SOC level, the top level of this dictionary. You can use this output as a starting point for further searches into the hierarchy.

Expanding a Branch One Level Using the Arrow Keys

You can expand and contract branches up or down one level in the Repository tree by clicking the arrow keys next to each expandable term.

Expanding a Branch in the Dictionary

You can expand the tree to one node at a time to view all data under one term in the dictionary hierarchy.

Reversing the Orientation of the Tree Window

You can orient your view of the data in the Terminology Data Tree Structure window to browsing up or down the dictionary hierarchy. Browsing up the hierarchy reveals a term's derivable path; browsing down shows its child relations.

Reversing the orientation also changes which term is in focus, because you must choose a dictionary term around which you change the direction.

To reverse the orientation, choose row of the term you want to be in focus, then click the reverse icon. The Repository tree refreshes, with the newly selected term now in focus.

Launching the Term Details Window

The Term Names for each record in the Terminology Data Tree Structure are hyperlinked to the Term Details window. The Term Details window includes all of the information in the TMS database regarding the selected term, including derived path and all of the term's relations.
