Nokia Acquires Mapping Startup Desti


Natalie Gagliordi of ZDnet reports, “It looks like Nokia is expanding its HERE Maps mapping business with its acquisition of the mapping startup Desti, a spinout from SRI International — the same group responsible for Apple’s Siri. This is the Finnish company’s first purchase since it sold its phone-making business to Microsoft last month.  Desti uses artificial intelligence and natural language processing to help travelers find what they’re looking for. For instance, if someone is looking for a low-cost place to stay on a business trip, Desti mines through hotel reviews and descriptions and weeds out the options that would appeal to partying college kids or lovers on a romantic getaway.” Read more

Berkeley Scientists Map How the Brain Sorts What We See reports, “Scientists have found that the brain is wired to put the categories of objects and actions we see daily in order, and have created the first interactive map of how the brain organizes these groupings. The result—achieved through computational models of brain imaging data collected while the subjects watched hours of movie clips—is what researchers call ‘a continuous semantic space.’ Some relationships between categories make sense (humans and animals share the same ‘semantic neighborhood’) while others (hallways and buckets) are less obvious. The researchers found that different people share a similar semantic layout. ‘Our methods open a door that will quickly lead to a more complete and detailed understanding of how the brain is organized. Already, our online brain viewer appears to provide the most detailed look ever at the visual function and organization of a single human brain,’ says Alexander Huth, a doctoral student in neuroscience at University of California, Berkeley and lead author of the study published in the journal Neuron.” Read more

The Semantics Behind Poderopedia

Alvaro Graves recently discussed the semantic technology behind Poderopedia, a project out of the Poderomedia Foundation that hopes to promote greater transparency in Chile by mapping and visualizing relationships among Chile’s elite. Graves writes, “One of the first technological decisions we made in Poderopedia… was to adopt semantic technologies to store and query data. These technologies allow us to represent a diverse set of relations between entities (people, companies, organizations) in a flexible way. The goal is to identify and express relations of power and influence of people and organizations. While we’re focused on Chilean political, civic and business leaders, this vocabulary can be used in other contexts with minor or no modifications at all.” Read more

New Paper: Directly Mapping Relational Databases to RDF & OWL

Juan F. Sequeda, Marcelo Arenas, and Daniel P. Miranker have written a new paper entitled Directly Mapping Relational Databases to RDF and OWL. According to the abstract, “Mapping relational databases to RDF is a fundamental problem for the development of the Semantic Web. We present a solution, inspired by draft methods defined by the W3C where relational databases are directly mapped to RDF and OWL. Given a relational database schema and its integrity constraints, this direct mapping produces an OWL ontology, which, provides the basis for generating RDF instances. The semantics of this mapping is defined using Datalog.” Read more
