Abstract: A distributed building management system for controlling a building control device of a building includes a virtual controller that is hosted on a computing device and an edge controller that is associated with the building control device. The virtual controller includes a virtual container or a virtual machine that has control logic that generates control commands for controlling the building control device. The edge controller includes control logic that is configured to at least selectively provide closed loop control of one or more functions of the building control device. The edge controller is in operative communication with the virtual controller and is configured to receive and execute the control commands generated by the virtual controller.

Abstract: A conversational analytics system may provide for a conversational interface to any relational database. A controlled natural language may be constructed in an automated manner from a given database (e.g., from schema and values associated with a relational database). For instance, a user natural language expression may be converted to an expression in the constructed controlled natural language and the controlled natural language expression may be converted into a sequence of one or more queries in a query language (e.g., queries in structured query language (SQL)). Such an intermediate controlled natural language may provide queries without ambiguity (e.g., as each expression or phrase in the controlled natural language may be mapped to one sequence of SQL queries). Accordingly, any natural language user utterance that ultimately follows the controlled natural language may be automatically converted into a sequence of one or more SQL queries sent to the database.

Abstract: Techniques for generating code for a flow are provided. The techniques include receiving a flow for an application to be deployed, wherein the flow comprises one or more sub-flows, identifying sub-flows of the flow that match existing sub-flows that are already running in separate flows by querying a run-time flow information repository, generating code for the flow, wherein the code comprises newly generated code for each of the sub-flows that do not match existing sub-flows that are already running in separate flows, and wherein the code also comprises one or more connectors to matching sub-flows that are already running in separate flows in lieu of generating new code for the sub-flows that match existing sub-flows that are already running in separate flows, and deploying the generated code for the flow and updating the run-time flow information repository with information pertaining to the flow.

Abstract: A flow pattern is generated from a single flow, in which the flow pattern describes a plurality of flows that are structurally similar to one another and perform similar tasks. End users are then capable of exploring the different flows of the pattern and selecting one or more flows based on high-level goals.

Abstract: A method and computer program product for assembling and deploying multi-platform flow based applications. An information processing flow that produces a result is assembled, the information processing flow includes components connected by data links, a component includes software code that describes at least one of an input constraint or an output constraint of the component, and at least two of the components are deployable on different computing platforms. The information processing flow is partitioned into sub-flows, such that for each sub-flow every component in the sub-flow is deployable on the same computing platform. The sub-flows are deployed on their respective computing platforms.

Abstract: A number of Web 2.0 sites support collaborative tagging systems, which allow users to tag resources with keywords. The tags enable search and retrieval of resources both for the user and for other users, using interfaces like a conventional search form or a tag cloud. A tag hierarchy-based search and retrieval system is provided that enhances the existing interfaces by improving search recall and allowing the discovery of even poorly annotated resources. The system uses tag co-occurrence information to automatically learn tag hierarchies. The learned hierarchies are used for automatically inferring additional tags to resources. These inferences are used to improve the recall of queries issued from a search form or via a tag cloud. The learned hierarchies can be viewed as an emergent ontology that is built up through the collaborative wisdom of a large number of users.
