Web scraping (web harvesting or web data extraction) is a computer software technique of extracting information from websites.
Web scraping is closely related to web indexing, which indexes information on the web using a bot or web crawler and is a universal technique adopted by most search engines.
Web Scraping refers to an application that processes the HTML of a Web page to extract data for manipulation such as converting the Web page to another format (i.e. HTML to WML).
Web Scraping scripts and applications will simulate a person viewing a Web site with a browser. With these scripts you can connect to a Web page and request a page, exactly as a browser would do.
What is Web Scraping Service?
Web Data Scraping offers affordable 100% risk-free, and accurate web scraping service , data extraction/scraping, text parsing, screen scraping, web data extraction, and website scraping and custom scraping development service to large companies as well as medium size companies which need data to be processed.
It relies on a stateless, client-server, cacheable communications protocol -- and in virtually all cases, the HTTP protocol is used.
REST is often used in mobile applications, social networking Web sites, mashup tools and automated business processes. The REST style emphasizes that interactions between clients and services is enhanced by having a limited number of operations (verbs). Flexibility is provided by assigning resources (nouns) their own unique universal resource indicators (URIs).
REST involves reading a designated Web page that contains an XML file. The XML file describes and includes the desired content.
The REST architectural style describes six constraints. The six constraints are:
Code on Demand
RESTful applications use HTTP requests to post data (create and/or update), read data (e.g., make queries), and delete data. Thus, REST uses HTTP for all four CRUD (Create/Read/Update/Delete) operations.
REST is a lightweight alternative to mechanisms like RPC (Remote Procedure Calls) and Web Services (SOAP, WSDL, et al.).
REST is not a "standard". There will never be a W3C recommendataion for REST, for example. And while there are REST programming frameworks, working with REST is so simple that you can often "roll your own" with standard library features in languages like Perl, Java, or C#.
As a programming approach, REST is a lightweight alternative to Web Services and RPC.
Much like Web Services, a REST service is:
Standards-based (runs on top of HTTP), and
Can easily be used in the presence of firewalls.
Like Web Services, REST offers no built-in security features, encryption, session management, QoS guarantees, etc. But also as with Web Services, these can be added by building on top of HTTP:
For security, username/password tokens are often used.
For encryption, REST can be used on top of HTTPS (secure sockets).... etc.
ChartsBin is a web-based data visualization tool that will allow everyone to quickly and easily create rich interactive visualizations with their own data. You can then share your interactive visualizations with others by embedding them in websites, blogs or sharing via Facebook or Twitter.
Using ChartsBin We can create Interactive graphs easily.
What makes ChartsBin different?
1)Create interactive visualizations online instantly! No installation required. No coding needed.
2)Embed the interactive visualizations in your own website or blog easily (simply copy & paste HTML code).
3)Export the visualizations as an image for presentation.
4)You can embed the interactive visualizations in social media websites (e.g.: Facebook.com, Digg.com, etc.)
5)We offers a public online gallery of interactive visualizations that have been derived from authentic sources such as books, government documents, technical reports, selected primary journal literature and websites.
Additionally, you can download compiled dataset (CSV, XLS, SQL).

Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data.
Augmented Reality is a type of virtual reality that aims to duplicate the world's environment in a computer. An augmented reality system generates a composite view for the user that is the combination of the real scene viewed by the user and a virtual scene generated by the computer that augments the scene with additional information.
Augmented reality (AR) is the integration of digital information with live video or the user's environment in real time.
Experiencing Augmented Reality ?
Three Simple Steps:
1)Recognition: Recognition of an image, an object, a face or a body
2)Tracking: Real-time localization in space of the image, object, face, or body
3)Mix: Superposition of a media (video, 3D, 2D, text, etc…) on top of this image, object, face or body.
1)Anyone can use it.
2)Knowledge, information increments are possible.
3)Experiences are shared between people in real time.
4)Video Games provide an even more “real” experience.
5)The mobile user experience will be revolutionized by AR technology as did gesture and touch (multi-modal interaction) in mobile phones.
6)Mobile usability is improved by AR acting as the primary interface.
1)Spam and Security.
2)Social and Real-Time vs. Solitary and Cached.
3)User Experience: Socially, using AR may be inappropriate in some situations.
