Keyword Services Platform - Architecture

Architecture

The following components comprise the Keyword Service Platform architecture:

• Keyword API. Set of standard Web services for various keyword tasks. These services are based on the Windows Communications Foundation and can be consumed by client applications (e.g., Microsoft Excel add-in) or mashups.
• Provider Plug-in Framework. System that allows researchers to incorporate new algorithms or data mining models within the Service Container. Each provider brings a specific keyword technology to the KSP architecture—for instance, keyword association, keyword extraction, or keyword classification.
• Security. Component that handles permissions that pertain to provider procedures (methods) and Stored Procedure implementation.
• Server Object Model. Data model that allows developers to leverage different services.
• Service Container. Set of providers that support various keyword technologies. Host to all service providers and Stored Procedures, which allows parallel execution.
• Shared Services. Core components, consisting of a crawler, in-memory data structures, word stemming algorithms, etc. These services are used by different providers and executed by stored procedures.
• Stored Procedures. Procedures for consolidating and centralizing the logic behind applications. Selected sets of these procedures are made available to users.

Developers may use .NET programming languages to create procedures that combine the use of different providers, or implement additional business logic processing based on the output from a provider.
