RECAP-KG: Mining Knowledge Graphs from Raw GP Notes for Remote COVID-19 Assessment in Primary Care

no code implementations17 Jun 2023 Rakhilya Lee Mekhtieva, Brandon Forbes, Dalal Alrajeh, Brendan Delaney, Alessandra Russo

By relying on support phrases mined from the SNOMED ontology, as well as predefined supported facts from values used in the RECAP (REmote COVID-19 Assessment in Primary Care) patient risk prediction tool, our graph generative framework is able to extract structured knowledge graphs from the highly unstructured and inconsistent format that consultation notes are written in.

Combining Experts' Causal Judgments

no code implementations20 May 2020 Dalal Alrajeh, Hana Chockler, Joseph Y. Halpern

We formally define the notion of an effective intervention, and then consider how experts' causal judgments can be combined in order to determine the most effective intervention.

Learning Classical Planning Strategies with Policy Gradient

no code implementations23 Oct 2018 Pawel Gomoluch, Dalal Alrajeh, Alessandra Russo

This enables using policy gradient to learn search strategies tailored to a specific distributions of planning problems and a selected performance metric, e. g. the IPC score.

Towards learning domain-independent planning heuristics

no code implementations21 Jul 2017 Pawel Gomoluch, Dalal Alrajeh, Alessandra Russo, Antonio Bucchiarone

Automated planning remains one of the most general paradigms in Artificial Intelligence, providing means of solving problems coming from a wide variety of domains.
