Link Analysis Overview

Free Trial

With Microsoft SQL Server, Sentinel Visualizer supports millions of entity and relationship records. Send all your data to the diagram or use search features like the Dataset Builder and Advanced Dataset Builder to select a subset of data for your link chart. Pick entities and relationships by their specific characteristics and links to each other. You can start big and drill down to details, or expand from individual entities one degree at a time until you include their entire network. Thousands of data points can be added to your diagram in a highly optimized, scalable, and shareable manner.

Once your data is on the Visualizer Diagram, a wide range of tools are available to customize and perform additional analysis. Here are some of the options on the panels:

Save, Share and Merge Diagrams

You can save your diagrams into the database to retrieve them in the future. They can be shared with other authorized users or kept private to yourself. You can also merge saved diagrams into your current diagram to combine multiple sets of analysis.

Rather than dumping all the data and finding the relationships, you can start with one entity and build from there. Use the Get Links feature to add to its network. You can expand it by the number of degrees (its links, the links of its links, etc.). When links are added the links among the entities are also displayed. You can also use the Entire Network feature to load all the connections related to the entity no matter how many degrees away they are.

Start with One Entity

The Between Selected feature lets you select multiple entities to add the fewest entities connecting them. Discover the smallest, tightest network among them.

For example, for Contact Tracing, three students tested positive. Between Selected quickly identifies the shortest path between them.

Combined with Data Refinement

Data Refinement lets you filter the type of Entities and Relationships on your diagram.

When data refinement is applied, Get Links respects those settings and only retrieves the entities and relationships that pass the filters. Easily focus on the data you want while excluding irrelevant data.

Sentinel Visualizer lets you apply advanced Link Analysis visualization to reveal the hidden relationships in your data. Leveraging your definitions of entities and relationships among them, turn rows and columns into visual data revealing multi-level hierarchical relationships. Quickly understand hidden links among people, places and events that are nearly impossible to see in traditional data grids.

Advanced Link Analysis with Custom Graphics

As entities are placed on the network and their links added, you can easily see the entities they have in common. This helps you focus your limited time and budget on the most suspicious and highest value targets.

Link Analysis and Data Visualization with Sentinel Visualizer

Sentinel Visualizer includes the ability to view your complex link chart in three dimensions. Fly through your relationships and/or animate them to see the links in an even more powerful way.
