Collection/item metadata relationships
In information organization systems, metadata is often attached to both collections and items. Collection metadata and item metadata are related: one can infer facts about items from descriptions of collections, and facts about collections from descriptions of items. This sort of reasoning, which …

Metadata-Aware Memory Security
… the cost of cloud memory security by optimizing metadata management. It minimizes the time overhead of memory encryption by improving how encryption-related metadata (e.g., write counters) is encoded and accessed. It also addresses the space overhead of memory isolation by novel coding of …

Anomaly detection using network metadata
… a preliminary framework which utilizes network metadata for detecting anomalies across enterprise networks. Network metadata helps describe properties of a network that may not be expressed by traffic data, and provides an additional metric to evaluate the overall health of a network. Examples of …

Fast, Metadata-private Anonymous Broadcast
… which messages. Trellis hides all network-level metadata, remains robust to changing network conditions, guarantees availability to honest users, and scales with the number of mix servers. Trellis provides three to five orders of magnitude faster performance and better network robustness compared …

Descriptive Phrases: Understanding Natural Language Metadata
… to be leveraged and analysed at deep levels. Metadata is a traditional way of getting leverage over the data. Deeper levels of analysis include language analysis, starting from purely string-based (keyword) approaches, continuing with syntactic-based approaches and now semantics is about to be …

Continuous metadata flows for distributed multimedia
… open hypermedia systems and knowledge systems. Metadata, in its many forms, has become the cornerstone for providing this structured knowledge above and beyond basic data and information. This thesis presents the rationale and requirements for continuous metadata, which supports the metadata …

Leveraging metadata in NoSQL storage systems
We present Wasef, a metadata system for NoSQL data stores. Wasef allows us to support important features such as data provenance, flexible data operations, and new administration tools. Our system has a general design that can be made compatible with most NoSQL data stores without imposing heavy …

A distributed metadata-private messaging system
… it is hard to deliver them without revealing metadata about which pairs of users are communicating. Scalable systems such as Tor are susceptible to traffic analysis. In contrast, the largest-scale systems with metadata privacy require passing all messages through a single server, which places …

Checking Metadata Usage for Enterprise Applications
… pay attention to con- figuration deployment with metadata usage (i.e., Java annotations and XML deployment descriptors). Different formats of metadata can correspond to each other. Metadata usually exist in multiple files. Maintaining such metadata is challenging and time-consuming. Cur- rent …

Context-aware semantic analysis of video metadata
Im Vergleich zu einer stichwortbasierten Suche ermöglicht die semantische Suche ein präziseres und anspruchsvolleres Durchsuchen von (Web)-Dokumenten, weil durch die explizite Semantik Mehrdeutigkeiten von natürlicher Sprache vermieden und semantische Beziehungen in das Suchergebnis einbezogen …

Template-Based Metadata Extraction for Heterogeneous Collection
… organizations have legacy collections that lack metadata. The lack of metadata hampers not only the discovery and dispersion of these collections over the Web, but also their interoperability with other collections. Unfortunately, manual metadata creation is expensive and time-consuming for a …

Federating Heterogeneous Digital Libraries by Metadata Harvesting
… heterogeneous digital libraries (DLs) by metadata harvesting. The objective of federation is to provide high-level services (e.g. transparent search across all DLs) on the collective metadata from different digital libraries. There are two main approaches to federate DLs: distributed …

Vuvuzela : scalable private messaging that hides metadata
… data is encrypted, it is difficult to hide metadata about who is communicating in the face of traffic analysis. Systems that offer strong privacy guarantees, such as Dissent [39], scale to only several thousand clients, because they use techniques with superlinear cost in the number of …

Metadata representation and management for context mediation
… data sources. In this thesis, we present a metadata representation and management layer that augments the Context Interchange framework. On metadata representation, a suite of XML-based representation of COIN metadata is fashioned. These XML-based representations include RDF, RuleML, and …

CONHUB: A METADATA MANAGEMENT SYSTEM FOR DOCKER CONTAINERS
… environment has a large number of native metadata, along with external metadata that are generated from users’ operations. If properly managed, these metadata can greatly facilitate the management of containers themselves but current container management frameworks have limited support for …

Methods metadata: curating scientific research data for reuse
… of research data relies on the provision of metadata and documentation. At present, scientists are not prepared to invest in the kind of rich description that will offer high functionality and interoperability in large-scale networked data systems. The absence of metadata not only makes data …

Strong metadata privacy for mobile devices and applications
… the confidentiality of messages. However, metadata, such as who has been messaging whom and when, can still be observed by platform operators, local internet providers, and other adversaries tapping into network traffic. This dissertation presents protocols and applications for mobile …
