*6.5. User Interactions*

We add some interactions in the system to help the researchers to use the system more smoothly. Filter. In order to help the experts have an understanding of the users of different score segments in the network, we provide filtering interaction through the color bar in the Figure 4a.

Search. The search interaction is provided by the search bar in Figure 4b. The researchers can search for the ego they find interesting in the Figure 4a.

Highlight. Most of the elements in the system can be highlighted. For example, when the mouse is over one line in the Figure 4b, the node of this line can be highlighted in the Figure 4a synchronously. When the mouse is over the alters in the Figure 4d, the location of it can be found and highlighted in the Figure 4f.

Zoom In and Out. The view in the Figure 4a can be zoomed in and out for the detail.

Click. If we find an ego in the Figure 4a,b or an alter in the Figure 4d we want to know more, we can click on the line or the circle, then the ego view or the detail view will be drawn.

Tips. Our system can give you some tips when you are confused or forget something.
