Research on transformer-based semantic reasoning and attack provenance mechanism for complex attack scenarios

Discover Artificial Intelligence
With the increasing complexity of cyber attacks, especially advanced persistent threats (APT) that exhibit multi-stage, stealthy, and long-cycle characteristics, traditional provenance methods struggle to effectively capture the semantic associations and

Polynomials for Multidimensional Provenance in Graph Databases

, 2021
In this thesis, we study the provenance of querying graph databases. Compared to using the semiring of polynomials as the most general form of provenance for relational databases (Green, Karvounarakis, & Tannen, 2007), we show that the most general provenance for querying graph databases can be represented by regular expressions over paths in the ...

Version [1.0]- [SAMbA-RaP is music to scientists’ ears: Adding provenance support to spark-based scientific workflows]

SoftwareX
While researchers benefit from Apache Spark for executing scientific workflows at scale, they often lack provenance support due to the framework’s design limitations. This paper presents SAMbA-RaP, a provenance extension for Apache Spark. It focuses on: (

Compressing Provenance Graphs

, 2011
The provenance community has built a number of systems to collect provenance, most of which assume that provenance will be retained indefinitely. However, it is not cost-effective to retain provenance information inefficiently. Since provenance can be viewed as a graph, we note the similarities to web graphs and draw upon techniques from the web ...

Using predicate and provenance information from a knowledge graph for drug efficacy screening

Journal of Biomedical Semantics, 2018
Background Biomedical knowledge graphs have become important tools to computationally analyse the comprehensive body of biomedical knowledge. They represent knowledge as subject-predicate-object triples, in which the predicate indicates the relationship ...

An Infrastructure for Software Release Analysis through Provenance Graphs

CoRR, 2018
Nowadays, quickly evolving and delivering software through a continuous delivery process is a competitive advantage and a way to keep software updated in response to the frequent changes in customers' requirements. However, the faster the software release cycle, the more challenging to track software evolution. In this paper, we propose Releasy, a tool

Semiring Provenance over Graph Databases.

, 2018
We generalize three existing graph algorithms to compute the provenance of regular path queries over graph databases, in the framework of provenance semirings – algebraic structures that can capture different forms of provenance. Each algorithm yields a different trade-off between time complexity and generality, as each requires different properties ...

Operationalising Graph-Based Linkage with Directory-Structured Project Frameworks

International Journal of Population Data Science
Motivations Consistently structuring complex linkage projects is essential for transparency, reproducibility, and effective management, and should ideally align with recurring linkage workflow tasks. We present a method that translates an abstract graph-

Constructing View of Uncertain Data Provenance for Scientific Workflow in Cloud Computing

Dianxin kexue, 2013
The view of data provenance in scientific workf1ow provides an approach of data abstraction and encapsu1ation by partitioning tasks in the data provenance graph（DPG）into a set of composite modu1es due to the data f1ow re1ations among them, so as to ...

Full Traceability and Provenance for Knowledge Graphs

Knowledge graphs (KGs) continue spreading into industrial use cases due to their advantages and superiority over classical data representations. A problem that has not yet adequately been solved for KGs is the traceability and provenance of changes, which can be required in an enterprise or by regulations.
