Managing Cloud Storage Obliviously

Tweet Vaishali Narkhede, Karuna Pande Joshi, Tim Finin, Seung Geol Choi, Adam Aviv and Daniel S. Roche, Managing Cloud Storage Obliviously , International Conference on Cloud Computing, IEEE Computer Society, June 2016. Consumers want to ensure that their enterprise data is stored securely and obliviously on the cloud, such that the data objects or their access patterns are not revealed to anyone, including the cloud provider, in the public cloud environment. We have created a detailed ontology describing the oblivious cloud storage models and role based access controls that should be in place to manage this risk. We have developed ...

AKSW Colloquium, 23.05.2016, Instance Matching and RDF Dataset Similarity

In the incoming colloquium, Mofeed Hassan will present the paper "Semi-supervised Instance Matching Using Boosted Classifiers" from Kejriwal et al., published in the proceedings of ESWC 2015 [ PDF ]. Abstract Instance matching concerns identifying pairs of instances that refer to the same underlying entity. Current state-of-the-art instance matchers use machine learning methods. Supervised learning systems achieve good performance by training on significant amounts of manually labeled samples. To alleviate the labeling effort, this paper presents a minimally supervised instance matching approach that is able to deliver competitive performance using only 2% training data and little parameter tuning. As a ...

Streamlining Management of Multiple Cloud Services

Tweet Aditi Gupta, Sudip Mittal, Karuna Pande Joshi, Claudia Pearce and Anupam Joshi, Streamlining Management of Multiple Cloud Services , IEEE International Conference on Cloud Computing, June 2016. With the increase in the number of cloud services and service providers, manual analysis of Service Level Agreements (SLA), comparison between different service offerings and conformance regulation has become a difficult task for customers. Cloud SLAs are policy documents describing the legal agreement between cloud providers and customers. SLA specifies the commitment of availability, performance of services, penalties associated with violations and procedure for customers to receive compensations in case of service ...

New UMBEL 1.50 Ships With 20 Linked Ontologies

I am proud to announce the immediate release of UMBEL version 1.50. This is a major effort that took a year to release. What is UMBEL? Let's start by explaining what is UMBEL for the ones that never encountered this project before. UMBEL stands for " Upper Mapping and Binding Exchange Layer ". It is a conceptual structure that is designed to help content interoperate between systems. UMBEL is a coherent general structure of 34 000 reference concepts which provides a scaffolding to link and interoperate other datasets and domain vocabularies. The conceptual structure is organized in a structure of ...

AKSW Colloquium, 09.05.2016: Hebrew MMoOn inventory, federated SPARQL query processing

In this week's colloquium Bettina Klimek will give a practice talk of the paper ' Creating Linked Data Morphological Language Resources with MMoOn - The Hebrew Morpheme Inventory ', which she will present at the LREC conference 2016 , 23-28 May 2016, Slovenia, Portorož. Abstract The development of standard models for describing general lexical resources has led to the emergence of numerous lexical datasets of various languages in the Semantic Web. However, there are no models that describe the domain of morphology in a similar manner. As a result, there are hardly any language resources of morphemic data available in ...

chmod 000 Freebase

Tweet He's dead, Jim. Google recently shut down the query interface to Freebase . All that is left of this innovative service is the ability to download a few final data dumps. Freebase was launched nine years ago by Metaweb as an online source of structured data collected from Wikipedia and many other sources, including individual, user-submitted uploads and edits. Metaweb was acquired by Google in July 2010 and Freebase subsequently grew to have more than 2.4 billion facts about 44 million subjects. In December 2014, Google announced that it was closing Freebase and four months later it became read-only. ...
