A system and method for creating an instance model is provided. The system provides an information extraction and modeling framework from wide spectrum of document types such as PDF, Text, HTML, LOG, CSV, images, audio/video files and DOCX. In this framework information is extracted and mapped on a domain conceptual model like ER model and the instance model is created. Initially a template model is created using the existing ER model and the plurality of data sources. The template model, the existing ER model and the information extracted from the plurality of data sources are then provided as input to generate the instance model. The system or method is not limited to extract information from log files. This can be useful for different types of files type if the structures and formats of data are different. The system can also be used with unstructured type of data sources.

Method and system for creating an instance model

Disclosed is method and system for modeling and executing service operation associated with technical service. Method comprises modeling of knowledge required for execution of service operation by representing factual knowledge and actionable knowledge in executable form. Modeling comprises representing standard operators and service operation. Service operation comprises parameters and rules presented in form of list of predicate-action pairs. Predicate-action pair comprises predicate and action. Predicate defines condition to be verified to comply with rule, and action specifies standard operator to be executed based on verification of condition. Method further comprises execution of service operation. Execution of service operation comprises selecting each predicate-action pair from list of predicate-action pairs and supplying subset of parameters to predicate of each predicate-action pair, verifying condition using subset of parameters, selecting standard operator based on verification of condition, supplying subset of parameters to standard operator, executing the standard operator by using subset of parameters.

Service modeling and execution

System and method for automatically generating and executing service operation, implementation for executing a task is disclosed. Task information and Entity relationship model associated with task is processed to identify part of the Entity Relationship Model matching with the task. Service operation template associated with the task is identified based on task information; and part of the Entity relationship model and service operation template is processed dynamically to generate and execute service operation implementation for executing the task. In another aspect, a part of an Entity relationship instance model associated with the task is identified dynamically based on the part of the Entity Relationship Model matching with the task and the task information; and part of the Entity relationship Instance model and service operation template processed dynamically, to generate and execute the service operation implementation for executing the task.
