Models Manager

Models Manager is a software component which allows users to define analysis models using the definitions defined in the LSI Designer. It is not a stand alone application and is usually used from within the Contextor client. It is designed so that third party client software can integrate it into their applications without using the Contextor client.

An analysis model includes definitions of:

• Types of entities used for inferring links

• Types of entities displayed in the results

• Filters on the entity data (such as only incidents that occurred in a particular time frame)

• Link criteria – what conditions constitute a link for each LSI

• General model parameters such as number of generations of links and maximum number of results to display in the results

• Scoring – calculation of the overall strength of a link according to the relative importance of each of the link criteria

The analytical mechanisms in Contextor or third party analytical mechanisms can then use the definitions from a particular model to execute a link analysis beginning with a specific entity of one of the entity types included in the model.

A simplified example of an analysis model using data from a police record management system might include the following:

• Types of entities: People, incidents, bookings, vehicles and phone numbers

• Filters on the entities: Include only incidents that took place during the past year and all vehicles involved in these incidents with local State registration plates.

• Link criteria – Do not include a link between a person and an incident if the person's involvement in the incident is as a police officer and include links between a person and a vehicle only if that person is currently the owner of the vehicle.

Scoring – Score links between a person and an incident according to their involvement in the incident as follows:

• Victim: 100

• Witness or passenger: 50

• Reporting person: 50

• Others: 20
