LSI (Link Support Information) Designer


LSI Designer is a stand alone application used by system administrators to design and customize SN-Sphere ™ applications. It provides a number of key advantages:

  • Flexibility - Applications can be designed and changed over time without customized programming

  • Cost effectiveness - Internal IT personnel can be trained to use it, thus lowering costs (total cost of ownership) 

  • Secure - No need to reveal methodology and data to external personnel

  • User Friendly - Maps the physical layer to a user friendly semantic layer used by all components of SN-Sphere. End users see names of entities, field names and all other data objects in their own language and terms.

    LSI Designer is used to:

  • Create application specific entities - Define what tables contain attributes of each entity including lookup tables. 

  • Design data forms for display and editing data by end users

  • Define a semantic layer over the physical layer for display purposes to end users and system administrators 

  • Define what tables contain link support information (LSI) - any type of data that can be used to infer relevant relationships and associations between entities 

  • Define Link Criteria (Licrits):

    Licrits - Link Criteria

    Link Criteria are one or more conditions used to infer associations between entities. An application can include definitions for any number of Licrits. An analysis model can contain one or more LSI and one or more Licrit.

    For example, a simple LSI is a table of call data records including the calling number and called number. This data indicates relationships between phones based on phone calls. Examples of Licrits could be, all phones that had an average of at least 10 calls between them over a period of one week or all phones that had bi-directional calls (each phone called the other phone at least once) and a total duration of calls of at least 5 minutes during the past 24 hours.

    Each Licrit may be assigned a relative score and the system will calculate an overall relevance score for each link based on both quantitative and qualitative criteria defined in the Licrits. A single link between two entities involved in a hostile network may be much more important that multiple links between two entities inccocently involved in a business.

    Each criteria pertains to one or more LSI and/or attributes of entities
    When creating analysis applications, it is cumbersome and inefficient to design, revise and maintain analysis mechanisms and solutions when using the nomenclature of the physical layer. Names of data tables, fields, schema and other data elements are unfriendly for IT personnel to work with and meaningless to analysts. The purpose of the LSI designer is to provide semantic and logical layers that can be easily used by SN-Sphere and other applications to build solutions. The LSI Designer allows definitions for three types of information for each application:

    or driver license), identifier of the vehicle (such as registration number), definitions used by PreStar™ and additional qualifiers such as date of ownership.
