Google Launches Knowledge Graph


Google introduced the Knowledge Graph, which is designated as the initial release, which are gradually being introduced American English users and consists of three elements:

• Links to the different sets of results based on the contextual meaning of any of the search terms
• Theme summaries of key facts visible in the sidebar
• "Information Boxes" that offer additional information based on the popular related queries. The first feature that Google


















Knowledge Graph gives users the option to choose from a set of results based on different meanings and interpretations of the query. For example, if you use Google search "Taj Mahal" as an example to illustrate how people may be looking for the same query, but with different contexts. One user may be looking for a blues musician Taj Mahal, and the other is more interested in booking the Trump Taj Mahal Casino Resort. Google shows in the sidebar box labeled "View results on" with brief descriptions and links to various sets of results based on the interpretation of queries.

















Another new element Search Knowledge Graph compiled key facts about popular topics and displayed on the sidebar.
How long will this take away the concept of place for advertising, time will tell.

Franc Inc. to Achieve Industry Leading 310 Billion RDF Triple Result


Franz Inc., is a leading supplier of technology for the graph database, with great support from Intel, has announced an advanced project in the field of Semantic Technology, which will first of all the others to load and carry NoSQL queries in database with billions of RDF statements, using a large Intel-based server. RDF (support data organized in triplets and quadruplets), the cornerstone of the Semantic Web, which offers a flexible way of representation graph database.

Applications are evident in various fields, particularly interesting application of the telecom companies, where they are needed billions of triples stored in graph databases. Eg. China Mobile has the need for 2 trillion triples, which kept detailed data on their customers.

310 billion triples theresult that has made the company Franz ,for only 78 hours of loading the 8-socketIntel Xeon processor 8870 E7 -basedserver with 2 terabytes of physical memory and 22 terabytes of physical disk .

The company are confident that with additional hardware can achieve so far elusive goal of a trilion triples.

Programming the Semantic Web

Programming the Semantic Web starts with a clear and practical introduction to the idea of the semantic web that will give any web developer the background necessary to comprehend the potential and usefulness of the concept. This is not a book for complete novices as it does anticipate that the reader will have previous experience with programming for the web, including the concepts of relational databases, familiarity with HTML and XML and perhaps a little RDF, and it would be useful to have some knowledge of Python and/or other computer programming languages.

Pull: The Power of the Semantic Web to Transform Your Business

Siegel was an early proponent of the Internet and started blogging in 1994, before the term was invented. He built some of the first Web sites and has been writing and lecturing about the Web since 1997. Always ahead of the curve, Siegel envisions the future of "smart computing" which will unfold over the next 10 years, where your data "follows you around" and is accessible from anywhere through the Web, predicting that hardware and operating systems will become obsolete as the Web itself becomes the computer.

Owl: Representing Information Using the Web Ontology Language

The book is well organized and it is very easy to read and follow.
You don't need to go back and read the previous line like many other technical books.
This book concerned about OWL1. But W3C recommented OWL2 lately.
The OWL 2 Web Ontology Language, informally OWL 2, is an ontology language for the Semantic Web with formally defined meaning. OWL 2 ontologies provide classes, properties, individuals, and data values and are stored as Semantic Web documents. OWL 2 ontologies can be used along with information written in RDF, and OWL 2 ontologies themselves are primarily exchanged as RDF documents.

W3C Launches RDF Working Group


W3C has formed a group, the RDF Working Group, whose mission is to update one of the basic standards of the Semantic Web: Resource Description Framework (RDF). The scope of the group is expanding the capabilities of the RDF standard, which the community has identified as desirable and important, based on its experience with the current standard, which dates from 2004. years, with no negative effect on the current implementation.

The most important and desirable editing capability will be to implement JSON serialization and TURTLE, and support the standard model for more charts and graphs store.

RDF Working Group meets in Amsterdam


RDF Working Group met face to face 13th and 14 April in Amsterdam. After two months of working group discussions focused on the tasks outlined, mainly updating RDF established to maintain the usefulness of RDF.
The most important topics were:
- The working group is expected publication draft Turtle Recommendations for 2 months.
- The working group concluded that the term "graph" overloaded. Current terms are "g-box" (a graphic container), "g-snap" (clip g-box at some point of time) and "g-text" (serialization graph, for example. Turtle or RDF / XML)
- Publication of JSON format for RDF. This issue has aroused the most responses, the Working Group has identified three cases of application of JSON-RDF syntax:
        - The first case is an example of application Talis JSON. This format mimics the RDF JSON format and as such is suitable for developers who are familiar with RDF-om
        - Another case of application is the use of RDF by JavaScript programmers. Examples of this can be found in the Linked Open Data API, as well as solutions BBC and NY Times, which present the RDF JSON
        - The third case is the most demanding applications and includes jednosatavan JSON object-oriented format that is acceptable to Web developers who need to present your data without it being too complicated. example of this approach is the JSON-LD .
Other topics were related to the number of unnecessary or archaic cleaning solutions known in some parts of the 2004 version of RDF.

Jena became project under Apache S.F.


Jena is a Java based framework for the development semantic web applications based on W3C standards and recommendations related to work with RDF and SPARQL query files. This project was initiated in HPLabs as an open source project and its recognized as one of the most important tools Semantic Web. HP does not help this project, nor is an employee at HP is currently working on this tool.

Jena is composed of the following modules:
 - tools for working with RDF files
 - readers and printers to work with RDF data formats such as RDF / XML, Turtle, N-Triples, NQuads, Trig
 - tools for working with database systems based on memory, files, and SQL relational databases
 - tools for working with OWL data formats
 - modules for inferences, based on the ontology and rules

Agreement with the Apache Software Foundation, refers to the following components of the Jena-based tools:
 - ARQ
 - SDB
 - TDB
 - IRI
 - Joseki

Apache environment will provide new opportunities for the development of Jena tools, primarily involve new people who want to help, will ensure the future development and reduce dependence on a small group of developers. There is also a dependence Jena tools with other Apache products such as Xerces, Lucene, Apache Commons
Jena currently has a large customer base in software industry and universities. HP closed the lab group in October 2009. People associated with a Jena project were moved to various companies and institutions connected with the Semantic Web. Most of these programmers are still working on the Jena project.

Facebook,Bing Partnership


Two years ago Microsoft bought a 1.6% stake in Facebook for $ 240 million, with the agreement that Bing offers users search data on the social network. Facebook has Open graph protocol that makes millions of users network profile ready for semantic search and analysis. These days, news arrived that a deal between giants extended. Over Bing will be selling advertising space on Facebook, Bing will offer consumers more search results, and these services are extended to the whole range of countries and becomes international.

Summary of this agreement is that Facebook users have a richer experience in search of data on social network, while Microsoft will get the opportunity to expand its offer and introducing new services over Bing search engine.
