Realities and fantasies of Web 3.0

14 Nov

In November 2006 , John Markoff wrote in the New York Times , using the term Web 3.0 , saying that she would find Web3.0new ways of mining human intelligence : ” From the billions of documents that form the World Wide Web (WWW) and the links that bind them, computer scientists and a growing group of new businesses … ” (see New York Times).

Definitions vary enough from those who think the customization features to the Semantic Web and barrel , from costumes like Conrad Wolfram thinks that Web 3.0 will be the place where ” the computer will generate new information ” , even pessimistic as Andrew Keen ( the Cult of the Amateur) you see in Web 3.0 a return to experts and authorities , calling it ” unrealisable abstraction ” , the idea of ​​connecting and organizing information on the Web

Consider a text actually founding text of James Handler , published in IEEE Computer January 2009 : ” Web 3.0 emerging ” on to explain that after countless laps around the Semantic Web technology has finally found that can help her accomplish – themselves.

The article explains the technology integrated into the emerging Semantic Web are already starting to produce results, from basic applications using RDF description ( in the description of resources, link data from multiple Web sites using a standard language SQL , the SPARQL query that RDF to connections that are ready in XML or OWL ontologies .

Far from being utopian , so the scenario of the Semantic Web is now real and results .

 

QR, what is

30 Oct

Being a two-dimensional code, QR (Quick Response) can store more information than exponentiallyQrCode one -dimensional bar code (white and black is 0 is 1) , storing content information complex , adjacent to the URL , for example, directs this blog .

The code was generated from the Google url shortener , then selecting ” details” .

Using some gadget camera or scanner , the code is converted into text, which can then be interpreted as using the text ( interactive) , with a URI address , phone number , located georeferenced , an email, a contact or SMS .

The QR Code was first used in the production of vehicles, but is now used both in inventory management and inventory control in industry and commerce.

QR codes are also common in magazines and advertisements , to record addresses and URLs , as well as detailed personal information.

 

Study shows use of technology in teaching

28 Oct

The study Learning Objects in the Classroom: Resources , Methods and Strategies for Improving the Quality of Education was developed over two years by a research group at the University UNESP Araraquara in Brazil, that evaluated the performance of 400 students from eight classes 2 and 3 ° years of high school with the class of learning objects , which are the technological resources that allow some interaction with the content , such as animations , simulations and educational games .

The use of games is already common and integrating the game Minegraft , eg using building blocks ,Minecraft is now used worldwide to teach literacy and mathematics aggregate biology (photo )

Research has shown that students in the classroom who had used technological tools had higher yields by taking as a basis the average five or below this value had a gain of 51 % performance in physics and mathematics , the project is coordinated by Professor Silvio Fiscarelli department didactic UNESP Araraquara .

Also, students with an average above five , had an average gain of 13 % , showing that the appropriate use of technology is beneficial to education .

For the project were used 20 technological tools in the classroom, with some created by the core teaching of UNESP , but most was used for educational repositories as BIOE ( Bank for International Educational Objects ) and rived , the SEED program (Department of Education distance ) or translated in international repositories .

The project now has the support of FAPESP (Research Support Foundation of the State of São Paulo ) , and extend the study to 660 students , with 600 students being done in the three years of high school , and extended to the areas of Portuguese , chemical and philosophy.

Facebook has decided to disable a privacy feature that allowed users to restrict who could find by searching their profiles within FaceInvisiblethe social network , while announcing a search engine competitor to Google (see note at O Globo) , so the question is visibility , unlike good movie ” the advantage of being invisible ” that discusses today’s teens .

Last year , many netizens had already disabled , but she allowed users to use them to bisbilhotas profiles and relationships in the social network without being known , is what makes many government agencies (see previous post ) .

The Facebook justified this removal percentage stating that ” single-digit ” of about 1.2 billion members who used the feature , but the fact is that this profile could be used for invasion of privacy , crimes and “security ” .

Users can continue to protect your privacy by limiting the public will have access to your posts ( just friends , certain groups or all users , for example) and can also prevent unwanted posts and give your opinion about negative campaigns that have invaded the network and also tags unwanted .

We remind users of the ” face” that can become invisible campaigns that denigrate the image of someone , or simply imprint fundamentalist nonsense , there is a tool on the side of each post to make these things invisible

 

Countries democracy on the Internet

14 Oct

A broaden study published by Freedom House, entitled Freedom in The World in 2013: Democratic BreakthroughsDemocraciaNoMundo in the Balance, shows the variations of democratic freedom with internet use varies in different countries, with highlights improvements in two countries that have made their “spring Arab “and highlight negative in countries where political struggle embarked on paths undemocratic.

But we can celebrate that a total of 90 countries can be considered truly free and democratic, an increase of three countries in relation to 87, 2011.

Worldwide, about 3 billion people, 43 percent of the population, has indeed all civil liberties, while 1.6 billion lived in countries where these freedoms are partially or almost completely limited.

This gives an index d remaining 34% who live in countries considered no liberties by Freedom House, which totals 2.3 billion people who suffer oppression in the world.

With a methodology that applies a three-pillar approach to capture the level of the Internet and freedom of ICT: barriers to entry, limits content and violations of user rights (surveillance, privacy and extra-legal harassment) content limits ( filtering and blocking content) and violations of user rights (includes up to prison).

The following table shows that advanced improvements in countries and countries that are declines:
