How to Design and Build Semantic Applications with Linked Data

2017-05-19, This webinar, presented by Dave Clarke, co-founder and CEO of the Synaptica® group of companies, will demonstrate how to design and build rich end-user search and discovery applications using Linked Data. The Linked Open Data cloud is a rapidly growing collection of publicly accessible resources, which can be adopted and reused to enrich both internal enterprise projects and public-facing information systems. The webinar will use the Linked Canvas application as its primary use-case. Linked Canvas is an application designed by Synaptica for the cultural heritage community. It enables high-resolution images of artworks and artifacts to be catalogued and subject ...

Enabling data forensics

I'm interested in how people share information, particularly data, on social networks. I think it's something to which it's worth paying attention, so we can ensure that it's easy for people to share insights and engage in online debates. There's lots of discussion at the moment around fact checking and similar ways that we can improve the ability to identify reliable and unreliable information online. But there may be other ways that we can make some small improvements in order to help people identify and find sources of data. Data forensics is a term that usually

Modeling and Extracting information about Cybersecurity Events from Text

Tweet Ph.D. Dissertation Proposal Modeling and Extracting information about Cybersecurity Events from Text Taneeya Satyapanich Tuesday, 16 May 2017, ITE 325, UMBC People rely on the Internet to carry out much of the their daily activities such as banking, ordering food and socializing with their family and friends. The technology facilitates our lives, but also comes with many problems, including cybercrimes, stolen data and identity theft. With the large and increasing number of transaction done every day, the frequency of cybercrime events is also increasing. Since the number of security-related events is too high for manual review and monitoring, we ...

new paper: Modeling the Evolution of Climate Change Assessment Research Using Dynamic Topic Models and Cross-Domain Divergence Maps

Tweet Jennifer Sleeman, Milton Halem, Tim Finin, and Mark Cane, Modeling the Evolution of Climate Change Assessment Research Using Dynamic Topic Models and Cross-Domain Divergence Maps , AAAI Spring Symposium on AI for Social Good, AAAI Press, March, 2017. Climate change is an important social issue and the subject of much research, both to understand the history of the Earth's changing climate and to foresee what changes to expect in the future. Approximately every five years starting in 1990 the Intergovernmental Panel on Climate Change (IPCC) publishes a set of reports that cover the current state of climate change research, ...

Fact checking the fact checkers fact check metadata

Tweet TL;DR : Some popular fact checking sites are saying that false is true and true is false in their embedded metadata I'm a fan of the schema.org claimReview tags for rendering fact checking results as metadata markup embedded in the html that can be easily understood by machines. Google gave a plug for this last Fall and more recently announced that it has broadened its use of the fact checking metadata tags. It's a great idea and could help limit the spread of false information on the Web. But its adoption still has some problems. Last week I ...

New paper: A Question and Answering System for Management of Cloud Service Level Agreements

Tweet Sudip Mittal, Aditi Gupta, Karuna Pande Joshi, Claudia Pearce and Anupam Joshi, A Question and Answering System for Management of Cloud Service Level Agreements , IEEE International Conference on Cloud Computing, June 2017. One of the key challenges faced by consumers is to efficiently manage and monitor the quality of cloud services. To manage service performance, consumers have to validate rules embedded in cloud legal contracts, such as Service Level Agreements (SLA) and Privacy Policies, that are available as text documents. Currently this analysis requires significant time and manual labor and is thus inefficient. We propose a cognitive assistant ...

SML-Bench 0.2 Released

Dear all, we are happy to announce the 0.2 release of SML-Bench, our Structured Machine Learning benchmark framework. SML-Bench provides full benchmarking scenarios for inductive supervised machine learning covering different knowledge representation languages like OWL and Prolog. It already comes with adapters for prominent inductive learning systems like the DL-Learner , the General Inductive Logic Programming System (GILPS) , and Aleph , as well as Inductive Logic Programming 'classics' like Golem and Progol . The framework is easily extensible, be it in terms of new benchmarking scenarios, or support for new learning systems. SML-Bench allows to define, run and report ...

At the AKSW Colloquium, on Monday 8th of May 2017, 3 PM, Lorenz B├╝hmann will discuss a paper titled " Type-based Semantic Optimization for Scalable RDF Graph Pattern Matching " of Kim et al. Presented at WWW 2017 , this work proposes a scalable query processing approach on RDF data that relies on early and aggressive determination and pruning of query-irrelevant data. The paper describes ongoing work as part of the RAPID+ platform project. Abstract Scalable query processing relies on early and aggressive determination and pruning of query-irrelevant data. Besides the traditional space-pruning techniques such as indexing, type-based optimizations that ...

Webinar: Me4MAP - A method for the development of metadata application profiles

2017-04-21, A metadata application profile (MAP) is a construct that provides a semantic model for enhancing interoperability when publishing data to the Web of Data. When a community of practice agrees to follow a MAP's set of rules for publishing data as Linked Open Data, it makes it possible for such data to be processed automatically by software agents. Therefore, the existence of a method for MAP development is essential to providing developers with a common ground on which to work. The absence of such a method leads to a non-systematic set of MAP development activities that frequently results in ...

Google search now includes schema.org fact check data

Tweet Google claims on their search blog that "Fact Check now available in Google Search and News". We've sampled searches on Google and found that some results did indeed include Fact Check data from schema.org's ClaimReview markup.
