Systems and methods for data analysis include correlating event data to provide process instances. The process instances are clustered, using a processor, by representing the process instances as strings and determining distances between strings to form a plurality of clusters. One or more metrics are computed on the plurality of clusters to monitor deviation of the event data.

Clustering based process deviation detection

Systems and methods for data analysis include constructing patient traces as a set of medical events for each patient of a patient population, the patient population being segmented based on patient outcomes. Medical events in one or more of the patient traces are reduced to provide processed patient traces. The processed patient traces are clustered to identify a cluster of patient traces. A process model is mined, using a processor, representing an aggregation of treatment pathways in the patient traces from the cluster. Patterns from patient traces are identified that are discriminative of patient outcomes. At least one of the patterns is represented with respect to the process model to identify treatment pathways correlated with the patient outcomes.

Extracting clinical care pathways correlated with outcomes

A method, system and computer program product for security model for workflows aggregating third party secure services. In one embodiment, a workflow model described in a workflow language is provided and configured to declare security requirements of a composite application integrating protected data from two or more external network resources. The method also incorporates providing an authentication service executing on at least one secure server computer. The authentication service is configured to conduct user authentication and authorization to access the protected data at the external network resources on behalf of the composite application executing on at least one host server computer according to the workflow language.

Techniques are disclosed for limiting execution of software programs. For example, a method comprises the following steps. A first set of program code is extracted from a second set of program code. The extracted first set of program code is parsed to generate a parsed structure. The parsed structure generated from the first set of program code is examined for one or more expressions predetermined to be unsafe for execution. The one or more expressions predetermined to be unsafe for execution that are contained in the first set of program code are detected. In one example, the first set of program code may be a script generated with the JavaScript&#x2122; scripting language and the second set of program code may be a business process.

Limiting execution of software programs

Techniques for structure-aware caching are provided. The techniques include decomposing a response from an origin server into one or more independently addressable objects, using a domain specific language to navigate the response to identify the one or more addressable objects and create one or more access paths to the one or more objects, and selecting a route to an object by navigating an internal structure of a cached object to discover one or more additional independently addressable objects.

Structure-aware caching

A computer implemented method, apparatus, and computer usable program product for processing application code. In one embodiment, a call is received to invoke a set of methods of annotated application code. The annotated application code includes a set of annotations specifying a selection of the set of methods. A selected method from the set of methods is invoked in response to determining that the call is valid according to the set of annotations. Thereafter, a subsequent set of valid methods for execution is identified based upon an annotation associated with the selected method.

Controlling navigation of application logic using annotated application code

A method, system and computer program product for simplifying a plurality of correlation rules of a graph. The method includes the steps of: receiving correlation rules; creating an undirected graph; removing redundant edges from the undirected graph; splitting nodes in the undirected graph; replacing a probability that an edge that connects two nodes to a seed value; modifying the seed value by adding a first value to said seed value and adding a second value to the first value; determining a maximum modified seed value; adding the maximum modified seed value to a probability that the uncertain edge connects two nodes; removing any temporary certain edge; and running a minimum spanning tree algorithm on said modified undirected graph.

Simplifying a graph of correlation rules while preserving semantic coverage

This invention provides a system and method that allows object oriented (OOP) applications to incorporate scripting easily and in a uniform manner. The Bean Scripting Framework (BSF) supports scripting on the OOP programming language-side, where the programming language runs and evaluates scripts, and also in cases where scripts run and control objects. The BSFManager provides scripting services for the application program as well as support services for scripting engines to interact with the OOP programming language runtime environment. The BSF also has a registry of known scripting languages which the application program can interact with. The scripting architecture allows OOP programming language applications to be customized and managed further downstream than previously possible.

Bean scripting framework

This invention provides for the implementation of dynamic &ldquo;event to method&rdquo; adapter class generation. Event to method adapter classes and objects are automatically and dynamically generated and wired to source and target objects as required using a runtime environments language such as the Beans Markup Language (BML). Adapter classes and objects are automatically and dynamically generated as required while the application program loads and runs. Dynamically generated classes and objects need to exist only at the time that a running application calls for the adapters use, and can be dynamically modified or exchanged in order to optimize the running application or modify application functionality.

Method and apparatus for dynamic generation of adapters

This invention provides a computer-method for parsing by enabling scripts to be expressed in a language which is syntax-compatible with the document surrounding them. A document is loaded having script and non-script components. Script components are identified and delineated, and are then passed to an interpreter, which returns an object corresponding to each script component. Then, script elements in the original document are replaced with the last returned object from the interpreter. If the returned object is a suitable Document Object Model (DOM) Node, it replaces the script element in the document structure. If the object is not a DOM node, the server invokes its string conversion method to obtain a textual representation, and replaces the script element with that text. After all BML markup block elements in the document have been processed, the altered document is delivered to the client.
