58 Working with the Activity Graph Service

The Activity Graph service provides a means of enlarging your sphere of interest in WebCenter Spaces by offering recommendations for new connections, suitable items, and relevant Spaces, and by returning more relevant search results. It does this by tracking application activities across users for a period of time. Based on these activities the Activity Graph engine starts to provide recommendations.

This chapter provides an overview of Activity Graph service features and describes how to use them. It includes the following sections:

For Activity Graph task flows to work, the Analytics schema (activities) must be installed and configured, and a connection set up between your application and the Analytics Collector.

See Also:

For more information, see the chapter "Managing the Analytics Service" in the Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter.

58.1 What You Should Know About the Activity Graph Service

The advent of Enterprise 2.0 has enabled users to contribute content at unprecedented rates. In view of this, there is now a need for better information retrieval technologies that are seamlessly integrated with Enterprise 2.0 products, such as WebCenter Spaces. The Activity Graph service provides the solution by leveraging collective intelligence, gathered by the underlying Activity Graph engine, to benefit search and social applications.

The Activity Graph service provides suggestions of people that a user may be interested in connecting with, based on existing connections and shared interaction with objects in the application. It also directs users to Spaces or items that may be of interest, based on similar interactions with those Spaces or items the user is currently viewing.

The Activity Graph service presents these suggestions based on data gathered and analyzed by the Activity Graph engine. The Activity Graph engine provides a central repository for actions that are collected by enterprise applications.

The Activity Graph service serves up its recommendations in the following three out-of-the-box task flows:

Note:

The Activity Graph service task flows display recommendations only if the Activity Graph service is configured in your application. For more information, see the section "Activity Graph Service Prerequisites" in the Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter.

Out of the box, the Activity Graph service tracks certain WebCenter objects and actions. However, you can extend the service to track other WebCenter objects or actions, or objects and actions from other applications.

58.2 Working with Activity Graph Service Task Flows

The Activity Graph service task flows expose the functionality available from the Activity Graph service.

This section includes the following subsections:

58.2.1 Adding an Activity Graph Service Task Flow to a Page

By default, the Recommended Connections task flow is included in each user's Profile Gallery, available through the Home Space. The Similar Items task flow is included, by default, in the Document Viewer Related Items pane for files, to show items similar to the currently viewed file.

To include any of the Activity Graph service task flows anywhere else, you must add the task flow to the appropriate page.

To add an Activity Graph service task flow to a page:

  1. Open the page in edit mode.

    See Also:

    For more information, see Section 17.3.1, "Entering and Exiting Page Edit Mode."
  2. Click Add Content in the target region to open the Resource Catalog.

  3. Navigate to the section of the Resource Catalog that contains the Activity Graph service task flows or search for the task flow.

    Tip:

    The presence or location of this component depends on how the Resource Catalog is configured. For example, in the default Resource Catalog, next to Social and Communication, click Open to expose a list that includes the Activity Graph service task flows.
  4. Click Add next to the task flow that you want to add to your page.

58.2.2 Working with the Recommended Connections Task Flow

The Recommended Connections task flow enables viewing and connecting to people considered to be similar to you.

Note:

The recommendations provided in the task flow reflect the contents of the activity graph when the Activity Graph Engines were last run. Activities that occurred after the last run are not included. For more information, see the section "Preparing Data for the Activity Graph Service" in the Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter.

This section includes the following subsections:

See Also:

For general information about connections, see Chapter 31, "Creating Your Social Network."

58.2.2.1 Learning More About a Recommended Connection

Before you connect with someone new, you probably want to find out a bit more about that person to determine whether it is really a connection that you want to make. The Recommended Connections task flow enables this by providing access to the user profile information and by including reasons why the recommendation has been made.

To view information about a recommended connection:

  1. Go to a Recommended Connections task flow.

    Tip:

    By default, you can find a Recommended Connections task flow on the Profile page in your Home Space.
  2. For each of your recommended connections, the task flow includes the name, title, and profile icon of the user. This provides a snapshot to help you decide quickly if you want to connect to this person.

  3. To find out more information about the user, click name of the user to display the User Detail popup.

    Note:

    Alternatively, you can click the user icon to display the user's Profile Gallery.
  4. In the User Detail popup (Figure 58-4), you can view additional information about the user, such as his or her location and current status. You can also choose to view the full profile or contact the user by email or instant message.

    Figure 58-4 The User Detail Popup

    Description of Figure 58-4 follows
    Description of "Figure 58-4 The User Detail Popup"

    Note:

    The information in the User Detail popup depends on the information that the user has provided in their profile, and the services that are enabled in the Space.
  5. Click anywhere away from the popup to close it.

  6. The task flow may also provide a reason why each person was recommended as a potential connection. For example, you may be connected to some of the same people or you may have worked on the same documents or wikis.

    Reasons for recommending a connection are:

    • You share connections with the user

    • You and the user edited one or more of the same items

    • You and the user worked in one or more of the same Spaces

    • You and the user tagged one or more of the same items

    Click the reason to find out more details. For example, a list of the connections you have in common, or a list of the objects that you have both worked on (Figure 58-5).

    Figure 58-5 Details for Reasons for Recommended Connections

    Description of Figure 58-5 follows
    Description of "Figure 58-5 Details for Reasons for Recommended Connections"

  7. Click anywhere away from the popup to close it.

  8. After examining this information you can decide whether to connect to this person, or remove him or her from the list of recommended connections.

58.2.2.2 Inviting a Recommended Connection to Connect with You

If you find a person in the list of recommended connections that you want to connect with, you can do so quickly from the User Detail popup or the user's Profile Gallery.

To invite a recommended connection to connect with you:

  1. Go to a Recommended Connections task flow.

    Tip:

    By default, you can find a Recommended Connections task flow on the Profile page in your Home Space.
  2. Find the person in the list of recommended connections.
