Running the Activity Graph Engines on a Schedule

12-12 Oracle Fusion Middleware Administrators Guide for Oracle WebCenter For more information, see the section Activity Graph in the Oracle Fusion Middleware WebLogic Scripting Tool Command Reference.

12.6.5 Renaming Actions and Node Classes

Use the WLST command renameAGNodeClass to change the URN of a node class currently registered with Activity Graph. For command syntax and examples, see the section renameAGNodeClass in the Oracle Fusion Middleware WebLogic Scripting Tool Command Reference. Use the WLST command renameAGAction to change the URN of an action currently registered with Activity Graph. For command syntax and examples, see the section renameAGAction in the Oracle Fusion Middleware WebLogic Scripting Tool Command Reference.

12.7 Setting Up Activity Rank for Oracle Secure Enterprise Search

Enterprise content contributed through WebCenter and Fusion applications has a rich structure that lends itself to using the Markov Chain Analysis mathematical technique. This technique is used by the Rank Engine to produce an Activity Rank for each node that improves end user searches by producing more relevant result sets. This is achieved by introducing a measure of the importance of various objects into the Oracle Secure Enterprise Search Oracle SES search index. This importance can then be factored into how results are ordered in combination with more standard search criteria term frequency, and so on. The determination of an object’s importance is predicated on the history of users’ interactions with that object. With Activity Rank, the importance of a person depends on the number of items the person creates and edits; the importance of those items; the number of people who connect with the person; and the importance of those people. The importance of an item depends on the importance of its author; the number of people who view, tag, and edit the item; and the importance of those people. The Rank Engine process can be divided into four phases: ■ Gathering—The Rank Engine queries the Analytics store for data about the connections between users and documents. ■ Reshaping—The data is transformed into a matrix. ■ Multiplying—The matrix is used to calculate Activity Ranks. ■ Result storage—The Activity Ranks are stored in the Oracle SES search server so that they can be used at search time. Candidates for Activity Rank are limited to an intersection of WebCenter Spaces objects having Oracle SES crawler implementations, WebCenter Analytics instrumentation, and registration for Activity Graph rank calculation. Note: These delete methods delete metadata from the schema. As a result of this, any associated data in the Activities database is removed the next time the Activity Graph engines are run. Note: These commands do not delete any metadata associated with the affected node class or action
