Pre-Act® is a Real Time Cognitive Solution Activities are the fundamental unit of Pre-Act®computation. All Pre-Act® functions - assessment, planning, execution, intent inference, and configuration - are driven by models of activities or tasks. PreAct interacts with sensors, GUIs or other external interfaces to acquire information and act on the world. Pre-Act® performs symbolic computation for cognitive reasoning, in order to decompose difficult problems into smaller, easier problems, to search intelligently for solutions, resolve conflicts among solutions or agents, to weigh evidence, combine evidence, and to select good options from multiple competing alternatives. Pre-Act®'s behavior is planned at run-time, according to a hierarchy of plans and goals, to adapt to current conditions and knowledge. Pre-Act®'s overall, top-level goals are typically more generic: complete assignments, detect and handle problems, preserve resources, be safe. Lower level subgoals decompose these broad, perennial goals into domain-specific, knowledge-intensive alternative subgoals and subplans, which Pre-Act®selects and instantiates with current data, in order to achieve its top-level goals as defined within the specific, current situation. PreAct supports distributed associates working as a team. An associate system built with the Pre-Act®framework is a single, cognitive solution for providing integrated intelligence to satisfy your requirements. The Modules in PreAct's Layered Architecture  | Information Manager adaptively configures and interacts with user interfaces | | | Error Analyzer detects unexplained deviations by the user from shared task models | | | Activity Performer interprets and executes situated scripts, acting to change world-state | | | Activity Planner decomposes and instantiates PreAct's plan hierarchy, to prescribe actions | | | Intent Interpreter uses plans and scripts to comprehend user behavior | | | Situation Assessor makes sense of incoming data about the world state | | | Situated Script Library contains procedural knowledge about activities | | | Plan-Goal Graph Library contains models of goals and plans for achieving them | | | Concept Graph Library contains the conceptual structures for modeling world state | | | Object Match Library is all the core routines for symbolic computation | Pre-Act® also has a foreign function interface that permit extension via external functions performing arbitrary computations and system activities. | | Common, shared mission objectives | | | Asset management and deconfliction | | | Decentralized or centralized control | Information Management | | Context sensitive alerting, display management | | | Analysis of multiple data types from multiple sources | | | Human-centered presentation | Integrated Knowledge Environment - IKE Pre-Act® now comes with IKE, our GUI-based Integrated Knowledge Environment, to cut your greatest cost for building intelligent systems: the knowledge engineering. Good tools make knowledge engineering faster and cheaper. ASI focuses on producing highly usable tools for building knowledge bases for PreAct, such as by providing a palette of knowledge constructs for designing domain-specific planning capabilities. |
