Provenance-based computing
… this dissertation, I examine the idea of using provenance metadata (the set of elements that have contributed to the existence of a piece of data, together with their relationships) instead. I show that considering provenance a primitive of computation enables the exploration of system …

Digital provenance - models, systems, and applications
<p>Data provenance refers to the history of creation and manipulation of a data object and is being widely used in various application domains including scientific experiments, grid computing, file and storage system, streaming data etc. However, existing provenance systems operate at a single …

Visualization of analytic provenance for sensemaking
… thus limits the performance. Analytic provenance captures both the data exploration process and and its accompanied reasoning, potentially addresses these information overload and disorientation problems. Visualization can help recall, revisit and reproduce the sensemaking process …

Unsupervised Workflow Discovery in Provenance Graphs
… the history of data - a concept known as data provenance - can thus be extremely important. In this thesis, we first address the need for a data provenance knowledge graph system, then address the need for being able to recover workflows that exist in such provenance networks, in an …

Provenance in personal documentary: My Mother's Village
… Supplementing the film, the exegesis component, Provenance in Personal Documentary interrogates the conceptual underpinnings of the creative research. 'Provenance', the key concept informing the production of My Mother's Village is a fine art term specifically â repractisedâ and retheorised here. …

Provenance in Open Data Entity-Centric Aggregation
An increasing number of web services these days require combining data from several data providers into an aggregated database. Usually this aggregation is based on the linked data approach. On the other hand, the entity-centric model is a promising data model that outperforms the linked data …

Secure Time-Aware Provenance for Distributed Systems
… this dissertation, we present Secure Time-Aware Provenance (STAP), a novel approach that provides the fundamental functionality required to answer such forensic questions -- the capability to "explain" the existence (or change) of a certain distributed system state at a given time in a …

XHTML documents with inline, policy-aware provenance
… a method for annotating XHTML documents with provenance metadata using RDFa. I present a method of performing copy and paste operations on XHTML documents that preserves this metadata. Finally, I apply these tools to the practical use case of an end user composing documents from multiple …

Towards a framework for making applications provenance-aware
… datos producidos por los sistemas, el término provenance ha surgido para referirse al conjunto de información que contribuye a la existencia de un dato. La captura de provenance conlleva una serie de beneficios que van desde la eproducibilidad hasta la responsabilidad, incluida la evaluación de …

Querying and managing opm-compliant scientific workflow provenance
<p>Provenance, the metadata that records the derivation history of scientific results, is important in scientific workflows to interpret, validate, and analyze the result of scientific computing. Recently,</p> <p>to promote and facilitate interoperability among heterogeneous provenance systems, the …

Document DNA: Distributed Content-Centered Provenance Data Tracking
… presents a new content-centered approach to provenance data tracking: the Document DNA. Knowledge workers are overwhelmed as they find it hard to structure, maintain, and find re-used content within their digital workspace. This issue is aggravated by the growing amount of digital data …

Trustworthy History and Provenance for Files and Databases
… We first focus on file systems and data provenance, and develop provably-secure schemes for securing file provenance information. With empirical evaluation using realistic file system workloads, we show that our scheme has low overhead, and can be deployed with minimal changes to existing …

Constructing provenance-aware distributed systems with data propagation
… architecture to maintain a detailed history or provenance of the data processed by it? Most existing distributed architectures can perform only one operation at a time. While they are capable of tracing possession of data, these architectures do not always track the network of operations used to …

Analytic provenance for sensemaking behavioural markers in visual analytics
Studying how analysts use interactions in visualization systems is an important part of evaluating how well these interactions support analysis needs, making sense of data or generating insights. As sensemaking is inherently a fluid activity involving transitions between mental and interaction …
