Recommendations

Info

Action • Recommended Topic: The system will recommend a topic (an event or an article) to a user based on interest of the user which is similar to the activities (event, article etc) of a Group. For example, we have a group G1 and a user U1. U1 is not a member of G1. In G1 there is an article/event published that there will be a “Jazz” concert in Milan. And U1 lives in Milan. So, the system will Recommend the U1 for the concert as the U1 also have Interest on “jazz” music. 3.4.2.2 Group Site View Create New Event Actor: Group Member Object: GroupMember, Group, Event Action • Create New Event: Group Member will create a new event in the Group. All the other Group Members will be notified about the new event. Post New Article Actor: Group Member Object: GroupMember, Group, Article Action • Create New Article: Group member will post a new article in the group. And all the group members will be notified about the new article.

Send Group Invitation Actor: Group Member Object: GroupMember, Group, User, Invitation Action • Send Group Invitation: Group Member will send Group Invitation to a User. If the User accepts the Invitation the User will become the Group Member of that Group. 3.4.3 Application Design A User can create a Group. He can invite other Users to become Group Members. He may have different activities in the Group. A User can have several interests which can be the Recommended Topic for the other User of the same Group. A Group Member can Post a Group Message or can create an Article or an Event. Other Group Member will get the notification message. Interesting Article can be shown as a Topic Recommendation to the other user. Figure 3.35 is the details diagram of the network. Using patterns and components we can build different types of recommendation. In this application a User play the main role. A user may have several friends through the Friend class. An User may have several friends. A user can become friends by accepting the Friend Invitation which sent by the other User. A User can create a Group. And he can invite other Users to become Group members. He may have different activities in the Group. A User can have several interests which can be the Recommended Topic for the other User of the same Group. A Group Member can Post a Group Message or can create an Article or an Event. Other Group Member will get the notification message. Interesting Article can be show as a Topic Recommendation to the other user. 61
