Partial Observability and Probabilistic Plan/Goal Recognition
Partial observability of the domain prevents the application of many plan recognition algorithms to real world problems. This paper presents a treatment for partial observability for a specific probabilistic plan recognition algorithm and an initial analysis of the runtime impact.
متن کاملPlan Recognition through Goal Graph Analysis
We present a novel approach to plan recognition based on a two-stage paradigm of graph construction and analysis. First, a graph structure called a Goal Graph is constructed to represent the observed actions, the state of the world, and the achieved goals as well various connections between these nodes at consecutive time steps. Then, the Goal Graph is analysed at each time step to recognise th...
متن کاملPlan, Activity, and Intent Recognition
Among the many impressive cognitive endowments of the human species, our physical intelligence and our social intelligence are two of the most essential for our success. Human physical intelligence uses intuitive theories of the physical laws of the world to maintain accurate representations of the state of the environment; analogously, human social intelligence uses folk–psychological theories...

We present a method for incremental intention recognition by means of incrementally constructing a Bayesian Network (BN) model as more actions are observed. It is achieved based on a knowledge base of easily maintained and constructed fragments of BNs, connecting intentions to actions. The simple structure of the fragments enables to easily and efficiently acquire the knowledge base, either fro...
متن کاملPlan and Activity Recognition from a Topic Modeling Perspective
We examine new ways to perform plan recognition (PR) using natural language processing (NLP) techniques. PR often focuses on the structural relationships between consecutive observations and ordered activities that comprise plans. However, NLP commonly treats text as a bag-of-words, omitting such structural relationships and using topic models to break down the distribution of concepts discusse...
