System and method for invoking functionalities using contextual relations

A system for identifying a contextually related instance, comprising:

• a graph for mapping a plurality of contextual relations among a plurality of instance types;
• a list of a plurality of functionality modules, each said functionality module being associated with at least one of said plurality of contextual relations;
• an input module configured for receiving from a client connected to the system via a network a query defining a contextual linkage between at least one known instance and at least one requested instance in said graph;
• and
• a processor which selects a group of said plurality of functionality modules according to a match between said contextual linkage and a sub-graph of said graph, divides said received query to a number of single step queries, and iteratively executes at least some of said number of single step queries for obtaining said at least one requested instance, wherein one of said number of single step queries includes a first member of said group with said at least one known instance for obtaining at least one intermediate instance and another of said number of single step queries includes a second member of said group with said at least one intermediate instance said at least one requested instance;
• wherein said functionality module implements at least one of a web service and a code script;
• wherein members of said group are executed in an order matching dependencies in said sub graph.

A method for obtaining a plurality of contextually related instances, comprising:

• performing the following by a system which comprises at least one server:
• identifying at least one object of interest of a first instance type in a data resource;
• providing a query defining a contextual linkage between said first instance type and a second instance type;
• identifying a match between said contextual linkage and a sub-graph of a graph comprising a plurality of contextual relations among a plurality of instance types;
• selecting a group of a plurality of functionality modules, each said functionality module being configured for providing at least one instance of one of said plurality of instance types;
• dividing said received query to a number of single step queries;
• and
• iteratively executing at least some of said number of single step queries,
• wherein one of said number of single step queries includes
• a first member of said group and used for acquiring at least one intermediate instance
• wherein another of said number of single step queries includes
• a second member of said group with said at least one intermediate instance and used for acquiring at least one instance of said second instance type;
• wherein each of said plurality of functionality modules implements at least one of a web service and a code script;
• wherein members of said group are executed in an order matching dependencies in said sub graph.
