Guided analysis view

Mining graph

The mining graph provides a visualization of the progress of your analysis. As the analysis proceeds, the graph becomes longer. You can move the graph around in the screen by holding down the cursor in the window and dragging the mouse. An example of the mining graph after further analysis steps is shown here.

The nodes represent the steps in the analysis. The left-most node displays the starting point with all documents and the right-most node shows the current point of the analysis. These two nodes also show the number of documents, which in the example above has been reduced from 20,000 to 30. To the right of the final node are suggested actions for further analysis. Some of the following actions may be suggested. Only the applicable actions will be shown. Click the action to execute it.

Analyze cause or characteristics

Watson™ Explorer Content Miner examines facets and suggests characteristic words and facets.

Analyze trends and anomaly

Facet Analysis

Show facet analysis view, if hidden.

Show Documents

Dashboard

Analysis dashboard can be saved

• Dropdown is added for user to select layout file. When user invoke the analysis, "New Layout" file is automatically created by system. The content of "New Layout" is changed when user do another analysis. If "append mode" is enabled in "Facet Analysis", results are added to "New Layout".
• To save Layout or edit metadata of saved layout, select layout and click "save" icon (3rd) icon. Then Save dialog is shown. User can set following properties
  • Name: Name of layout file
  • Sharing Mode: Private or Shared (Private is visible for author, Shared is visible for all users)
  • Add to Facet Analysis option (New analysis type is added to "Facet Analysis" pane, it invoke the same analysis conditions of this dashboard is
  • User can select Save or Save As
    
• To delete Layout, click the Delete icon
• If you modified the saved layout, a mark ("*") is added to the layout name. To revert, click the Reset icon
• Click the Auto Layout icon to re-layout by using the system default layout algorithm

Analysis dashboard customization

• Dashboard save includes following things

  • Customization of Layout
  • Customization of each Analysis Results

• Layout

  • Move by dragging the black border header area of each pane
  • Resize by dragging the resize handle at the right bottom of each pane

• When a layout is not saved (New Layout), when you add the new analysis results in the current layout, or remove existing ones, the system automatically re-lays out the whole content

• When a layout is saved, when you add the new analysis results in the current layout or remove existing ones, try to keep the existing saved layout as much as possible.

  Each analysis result

  
  • You can customize the analysis from the toolbar or result visualization
  • The Toolbar is expanded when a single analysis result is in the dashboard; for multiple results, the toolbar is collapsed by default

    • Label: Click on a label, move to label edit mode. Move the focus to apply a change

      
      

  • Filter: User can filter current values by text (not saved)

  • Number of Results: User can change the number of results of current analysis from here (saved)

  • Selection Mode: By default, user can select multiple values in each analysis result. But if a user specifies "single" mode, the user can select only one value at a time. (saved)

    • Multiple: Select multiple values
    • Single: Select a single value
    • Clear Selection: Clears current item selection in this pane

  • Filter Others: If user enabled this option, when user select some values in this analysis results, its query is applied to the other analysis results in same layout to filter. For example, if you have "Maker" facet result and "Products" facet results in same layout, enabled "Filter Others" of "Maker" and select some value of it, then only Products of selected Maker is displayed. This is very powerful enhancement of real analysis scene. (saved)

    When you enable a filter, and select items from the filter enabled pane, then other panes are updated. The data of each pane is updated but its item selections are kept. This behavior may be confusing: each pane shows the top "N" (default it 50) items in the pane, but because a selected item is not included in the top "N" items, it may not always be shown in the pane.

  • Boolean Operator: Select AND or OR operator to create query from multiple values.(not saved)

  • Export: Download as Image is added. User can get the screenshot PNG File of current analysis. (not saved)

  • Visualization: User can select visualization type. (saved)
