Hierarchical Task Network (HTN) planning with Task Insertion (TIHTN planning) is a formalism that hybridizes classical planning with HTN planning by allowing the insertion of operators from outside the method hierarchy. This additional capability has some practical benefits, such as allowing more flexibility for design choices of HTN models: the task hierarchy may be specified only partially, s...

In this paper we present the application of two RDF graph kernels to task 1 and 2 of the linked data data-mining challenge. Both graph kernels use term vectors to handle RDF literals. Based on experiments with the task data, we use the Weisfeiler-Lehman RDF graph kernel for task 1 and the intersection path tree kernel for task 2 in our final classifiers for the challenge. Applying these graph k...

A modular strategy for scheduling iterative computations is proposed. An iterative computation is represented using a cyclic task-graph. The cyclic task-graph is transformed into an acyclic task-graph. This acyclic task-graph is subsequently scheduled using one of the many well-known and high-quality static scheduling strategies from the literature. Graph unfolding is not employed and the gener...

Code embeddings have seen increasing applications in software engineering (SE) research and practice recently. Despite the advances embedding techniques applied SE research, one of main challenges is their generalizability. A recent study finds that code may not be readily leveraged for downstream tasks are particularly trained for. Therefore, this article, we propose GraphCodeVec , which repre...
