Any query put into the widget will be combined with the current dashboard selection using an AND operator.
Significant Terms
- The Significant Terms provides visual information about terms which are especially significant in a dataset, comparing to another dataset.
- Significant Terms allow to reveal the uncommonly common. This means, that it shows which terms show a significant different value distribution in a foreground-dataset when compared to a background-dataset. This requires a certain amount of documents to work, the more terms there are in a facet, the more documents are needed to get a meaningful answer. In Squirro the background-dataset is what is defined in an unmodified dashboard. The foreground-dataset is constructed from the background-dataset and includes the current selection. If there is no selection, meaning that the foreground- and the background-dataset are equal, the term frequency is shown (except if the facet is
body,titleorsummarywhere this operation is too costly). - Significant terms work very well on facets with few values, meaning if computed on a
body,titleorsummaryfield, there are much more documents needed to get a significant term to show-up. One workaround for this restriction is to use phrase- or term detection and index those phrases/terms in a separate facet field. This has shown to improve the results vastly while also not requiring a lot of documents.
The Significant Terms configuration for facet content fields looks like the following:
- When configuring over a special content field (body, title, summary), one is asked also to provide language and the maximum number of results returned.
- The maximum number of results field affects performance, so exercise with caution when increasing the limit.
Smart Filters
The Smart Filters widget can be used to display the list of currently defined Smart Filters and apply them to the Dashboard.
...
The Word Cloud displays values of several (between 1 and 7) different facets at once.
World Map
- World map widget displays allows you to visualise the geographical data on a worldmap.
- Inorder for this widget to work, the items need to be tagged with their geo-point co-ordinates.
- The widget offers map view and satellite view along with zoom and search functionality.
- Dragging and zooming the map causes the dashboard to filter by the markers visible on the widget.
