Q & A – Callimachus: Semantic Web Apps Made Easy

Q&A Session for "Callimachus: Semantic Web Apps Made Easy"

Q: Was Callimachus arguing against a "single inheritance" hierarchy or arguing against a universal "Thing" which is the superclass of all things?

A: Callimachus, the Greek poet, could easily justify placing many of his scrolls (of short poems) in multiple bins. He argued that some things have multiple categories (or types) and could not be arranged in single hierarchy.

RDFa makes it easy for Web publishers to expose data on the Web, but RDFa can also make it easy to develop Web data applications. Watch how easy it is to replace complex data schemas and their SQL queries with simple RDFa attributes in your HTML markup!

Strengthening the Four Pillars of the Advanced Enterprise through Semantics; Data, Processes, Resources, and Access

280250

Data management, process management, access management, and resource management form the four pillars of the advanced computing enterprise. This includes critical technologies such as databases, web services & service oriented architectures (SOA), mobile devices, and cloud computing. Semantics helps adapt and unify them to your current enterprise to allow rapid adoption and effective use.

Q&A Session for The National Information Exchange Model and Semantic-Driven Development

Q&A Session for "The National Information Exchange Model and Semantic-Driven Development"

Following the webcast, Dan McCreary answered questions from the live audience. Here is a transcript of that discussion.

Q: My understanding is that NIEM is not considered a Federal Information Exchange Model and does incorporate Federal, State, Local, Tribal and Private Sector partners.

The National Information Exchange Model and Semantic-Driven Development

280144

Since 2002, several US federal agencies have been deploying XML standards for the exchange of complex data sets. Led by a large project at the US Department of Justice and homeland security, there are now hundreds of states and vendors supporting an emerging XML standard called the National Information Exchange Model or NIEM. This presentation will look at the NIEM processes and show how they are being used to promote semantically precise data exchanges as well as promoting transparency in government.

Semantic Search technology in the Semantic Web community is often understood as retrieval of knowledge from tagged data such as RDF sources, which require substantial formatting and markup to realize. Understanding unstructured query and document text and conducting searches according to their meaning is another approach, exemplified by linguistically rooted semantic matching, ontological knowledge-based semantic interpretation, and statistically based semantic similarity search.

This panel will look at different ways to tackle semantic search as a problem of text understanding. Powerset division of bing’s natural-language processing engine does deep syntactical analysis to determine the meaning of a query or a sentence. Hakia relies on a language-independent ontology model and an ontology-based English lexicon to translate text into a representation of its meaning. RiverGlass has developed an ontological semantic approach to search and text analytics, emphasizing the in-context, linguistic meaning of textual content in order to return truly relevant results in response to information requests. TextWise’s Semantic Signature matching looks for similarities between a query and text at the topic level.
