How to Add Semantic Markup to your Site or Application? Start Here!

Structured Data on the Web - structured-data.org

Recently, a new resource appeared on the Web to help developers navigate the waters around various approaches to adding semantic markup to websites and applications. We caught up with the creators of the newly launched  structured-data.org, to learn more about this project.  They are:

Q: What is “Structured Data on the Web” (the site and the concept)?

GK: We wanted to provide a place for people to learn about the different ways in which publishers can add semantic information to their web sites and applications. There is confusion in the marketplace, partly due to the introduction of schema.org, which has raised the awareness of structured data with web developers. structured-data.org is a one-stop-shop to learn about the different mechanisms available to developers to take advantage of this.

Brief Survey of NLP Tools & Services

We often discuss text analysis and natural language processing (NLP) here at SemanticWeb.com, so we were pleased to see this nice, if incomplete, survey of tools and services for NLP. The article begins, “Although Natural Language Processing (NLP) has been around since the 1950s in the computer science world, more and more uses for this powerful technology are being uncovered every day. Search engines like Google use NLP as one of the ways they extract meaning from web pages, Microsoft has a whole team of people working on NLP projects, and a number of universities have dedicated major resources working on the advancement of NLP, but what about everyone else? NLP has many uses going beyond behemoth websites including uses for the enterprise, small business, and end users.” Read more

Let the Sun Shine In On the SuperCongress, 2012 Election Candidates, And All The Rest

It’s been a summer of drama in the U.S.: the battles around the debt limit and the S&P’s downgrading of the U.S.’s Triple A rating, all fueling citizens’ already fueled concerns about the economy and jobs and the nation’s future. Now, the controversial Super Congress is taking shape to cut discretionary funding and direct spending by $1.5 trillion through 2021.

In light of the roller-coaster ride, any takers to see what they can do with the Sunlight Foundation Sunlight Lab’s recently introduced Influence Explorer Text API? Another step in the Foundation’s mission to make government transparent and accountable, the API provides real-time textual analysis for the Foundation’s Inbox Influence plug-in that lets users see in their emails the political contributions behind names mentioned in these messages.

We had a chance to have an email conversation with Ethan Phelps-Goodman, Project Lead: Data Commons, at the Sunlight Foundation to better understand what the API can do.

Semantic Web Blog: With lawmakers tapped for the Super Congress, we’re starting to see stories about their political patrons, their special interest connections, and so on. How can the Influence Explorer API be leveraged to help the public better understand these individuals and their political backgrounds/agendas? And if you’ve been using it to that end in recent days, come across anything interesting the public should know about?

Phelps-Goodman: Influence Explorer can give a great deal of background on the fundraising activities of members of congress. A recent series of posts from The Atlantic is a great example. Our own Reporting group also did a series of influence profiles of the Super Congress. Even more interesting will be the lobbying activity around the Super Congress’ work. Tracking the money spent on lobbying will have to wait until the disclosure period ends at the end of the year. But you can get a head start on things now at our Lobbyist Registration Tracker, where new lobbying contracts are updated as they happen.

Dutch Legislation Made Available as Linked Data

A recent article reports, “The Leibniz Center for Law of the University of Amsterdam has made all Dutch legislation available as CEN MetaLex and Linked Open Data through the MetaLex Document Server portal (MDS). ‘The XML source documents currently made available by the Dutch government are simply not good enough’, says Rinke Hoekstra, researcher at the Leibniz Center, and the Knowledge Representation group of the VU University Amsterdam.” Read more

Why Ontologies are Needed in Health Care Applications

Joel Amoussou addressed the question recently of why ontologies are needed in health care applications. Amoussou writes, “at the practical level, ontologies can help us verify the soundness of statements in messages based on our conceptualization of the world. Information models in healthcare often take the form of an XML schema, a Schematron schema, or a relational database schema. One distinguishing characteristic of ontologies is that they are based on an Open World Assumption (OWA) which is based on the AAA slogan or Anyone can say Anything about Any topic. Statements that are not included in an ontology are considered unknown as opposed to false.” Read more

Securing Ourselves through Semantics

A recent article takes a look at three IT trends that are driving information security evolution. One of these trends is semantic security: “Like IT, humans network to exchange information. However, information security works at a syntactic level, while humans work at a semantic level. Commonly implemented security controls can detect individual words or terms and can block entire traffic for certain ports or addresses. These security controls currently do not work at the semantic level. I may accept and trust news from a friend that ‘the Dow dropped 500 points today.’ However, I would not trust the same friend with the statement that ‘today’s 500 point Dow drop proves the financial collapse of the United States will initiate Armageddon.’” Read more
