V1.3 Specific: Site Administrators can rebuild their search, class group cache, visualizations, and inferencing in the Site Admin interface. It is important to build the visualization code after ingesting publication data or it will take a long time to display the visualization to the user.

Rebuild visualization cache –

Large-scale visualizations like the Temporal Graph or the Map of Science involve calculating total counts of publications or of grants for some entity. Since thismeans checking also through all of its sub-entities, the underlying queries can be both memory-intensive and time-consuming. For a faster user experience, we wish to save the results of these queries for later re-use.

...

 To this end we have devised a caching solution which will retain information about the hierarchy of organizations-namely, which publications are attributed to which organizations-by storing the RDF model. We're currently caching these models in memory. The cache is built (only once) on the first user request after a server restart. Because of this, the same model will be served until the next restart. This means that the data in these models may become stale depending upon when it was last created. To avoid restarting the server in order to refresh the cache, administrators can use the Rebuild visualization cache link.
This works well enough for now. In future releases we will improve this solution so that models are stored on disk and periodically updated.
