Our coverage of semantic technologies goes back to the early 90s when search engines focused on searching structured data in databases were looking to provide support for searching unstructured or semi-structured data. This early Gilbane Report, Document Query Languages – Why is it so Hard to Ask a Simple Question?, analyses the challenge back then.

Semantic technology is a broad topic that includes all natural language processing, as well as the semantic web, linked data processing, and knowledge graphs.

Semantic analysis (machine learning)

In machine learning, semantic analysis of a corpus is the task of building structures that approximate concepts from a large set of documents. It generally does not involve prior semantic understanding of the documents. Latent semantic analysis (sometimes latent semantic indexing), is a class of techniques where documents are represented as vectors in term space. A prominent example is PLSI. Latent Dirichlet allocation involves attributing document terms to topics.

AWS announces QuickSight Q

December 1, 2020 /

Amazon Web Services, Inc. (AWS) announced QuickSight Q to make it simpler for end-users to get more value from their business data using machine learning, among other new analytics analytics capabilities.

Amazon QuickSight Q is a machine learning-powered capability for Amazon QuickSight that lets users type natural language questions about their business data and receive accurate answers in seconds. As users begin typing their questions, Amazon QuickSight Q provides auto-complete suggestions with key phrases and business terms, and automatically performs spell-check and acronym and synonym matching, so users do not have to worry about typos or remembering the exact business terms for the data. Amazon QuickSight Q uses deep learning and machine learning (natural language processing, schema understanding, and semantic parsing for SQL code generation) to generate a data model that automatically understands the meaning of and relationships between business data, so users receive accurate answers to their business questions and do not have to wait for a data model to be built. Amazon QuickSight Q comes pre-trained on data from various domains and industries like sales, marketing, operations, retail, human resources, pharmaceuticals, insurance, and energy.

Ontotext Platform 3.3 streamlines knowledge graph lenses & GraphQL interfaces

November 20, 2020 /

The new version of the Platform introduces a web-based administration tool that enables engineering teams to generate, enrich, validate and manage knowledge graph schemas, and comes with a major new component included, Ontotext Platform Workbench, a web-based administration interface to the platform. This simplifies the work of the subject matter experts by lowering the burden of knowing all platform configuration endpoints and commands and streamlines adoption with a graphical interface. The Ontotext Platform Workbench provides the ability to generate, validate and manage schemas using a wizard that guides the user through the process step by step.

Schemas, comprised of declarative definitions of semantic objects, are at the heart of the zero-code approach for access and management of knowledge graphs in Ontotext Platform 3. These schemas act like a lens to focus on specific parts of a large-scale knowledge graph, enabling querying and updates via GraphQL interfaces. This makes it easier for application developers to access knowledge graphs without tedious development of back-end APIs or complex SPARQL. The underlying Semantic Object service implements an efficient GraphQL to SPARQL translation as well as a generic configurable security model.

In earlier versions the setup of the Platform license required some technical skills, and often users without a strong IT operations background had difficulties configuring the license in the docker compose file. With the new version all users can use the Workbench and set up the license much easier and avoid issues related to license path, operation system specifics and others.

Inrupt releases enterprise version of Solid Server

November 9, 2020 /

Tim Berners-Lee’s (unedited) announcement…

Today marks a huge milestone in Inrupt’s journey to deliver on my vision for a vibrant web of shared benefit and opportunity. I’m thrilled that the first enterprise-ready version of a Solid Server, Inrupt’s ESS, is now available for businesses and organizations. It’s the fruit of two years of work by our outstanding team. These technologies will fundamentally change how organizations connect people with their data and create value together. It’s going to drive groundbreaking new opportunities that not only restore trust in data but also enhance our lives.

We’ve reached this milestone alongside a trusted cohort of early adopters including the BBC, NatWest Bank, the UK’s National Health Service, and the Flanders Government. They’re each proving what’s possible for their users by changing the way they think about, share, and use data. You can read more about these important pilots in this blog post from Inrupt CEO, John Bruce.

The web was always meant to be a platform for creativity, collaboration, and free invention – but that’s not what we are seeing today. Today, business transformation is hampered by different parts of one’s life being managed by different silos, each of which looks after one vertical slice of life, but where the users and teams can’t get the insight from connecting that data. Meanwhile, that data is exploited by the silo in question, leading to increasing, very reasonable, public skepticism about how personal data is being misused. That in turn has led to increasingly complex data regulations.

There had to be a better way. The Solid architecture provides that better way.

I founded Inrupt to trigger an inevitable shift in how the web operates, to mobilize resources and set a long-term direction in motion. Today that shift takes a significant step.

The technologies we’re releasing today are a component of a much-needed course correction for the web. It’s exciting to see organizations using Solid to improve the lives of everyday people – through better healthcare, more efficient government services and much more.

These first major deployments of the technology will kick off the network effect necessary to ensure the benefits of Solid will be appreciated on a massive scale. Once users have a Solid Pod, the data there can be extended, linked, and repurposed in valuable new ways. And Solid’s growing community of developers can be rest assured that their apps will benefit from the widespread adoption of reliable Solid Pods, already populated with valuable data that users are empowered to share.

Ultimately, this new foundation of trust and cooperation will lead to entirely new business models that actually benefit users as well.

Starting today, more organizations worldwide can take the first step towards building a trusted web where innovation flourishes, and everyone – businesses, developers, and web users – share the benefits. We hope you’ll join us on this exciting journey.
