Web scraping (web harvesting or web data extraction) is data scraping used for extracting data from websites. Web scraping software may access the World Wide Web directly using the Hypertext Transfer Protocol, or through a web browser.
The World Wide Web (Web) is a popular and interactive medium to disseminate information today.
The Web is huge, diverse, and dynamic and thus raises the scalability, multi-media data, and temporal issues respectively.
Web scraping is a technique for gathering data or information on web pages. You could revisit your favorite web site every time it updates for new information. Or you could write a web scraper to have it do it for you!
It is a method to extract data from a website that does not have an API or we want to extract a LOT of data which we can not do through an API due to rate limiting.
Through web scraping we can extract any data which we can see while browsing the web
The Internet is the largest source of information created by humanity. It contains a variety of materials available in various formats such as text, audio, video and much more. In all web scraping is one way. It is a set
of strategies here in which we get information from the website instead of copying the data manually. Many Webbased data extraction methods are designed to solve specific problems and work on ad-hoc domains. Various tools and technologies have been developed to facilitate Web Scraping. Unfortunately, the appropriateness and ethics of
using these Web Scraping tools are often overlooked. There are hundreds of web scraping software available today, most of them designed for Java, Python and Ruby. There is also open source software and commercial software.

Smart Crawler: A Two Stage Crawler for Concept Based Semantic Search Engine.iosrjce
The internet is a vast collection of billions of web pages containing terabytes of information
arranged in thousands of servers using HTML. The size of this collection itself is a formidable obstacle in
retrieving necessary and relevant information. This made search engines an important part of our lives. Search
engines strive to retrieve information as relevant as possible. One of the building blocks of search engines is the
Web Crawler. We tend to propose a two - stage framework, specifically two smart Crawler, for efficient
gathering deep net interfaces. Within the first stage, smart Crawler, performs site-based sorting out centre
pages with the assistance of search engines, avoiding visiting an oversized variety of pages. To realize
additional correct results for a targeted crawl, smart Crawler, ranks websites to order extremely relevant ones
for a given topic. Within the second stage, smart Crawler, achieves quick in – site looking by excavating most
relevant links with associate degree accommodative link -ranking
International Journal of Computational Engineering Research (IJCER) is dedicated to protecting personal information and will make every reasonable effort to handle collected information appropriately. All information collected, as well as related requests, will be handled as carefully and efficiently as possible in accordance with IJCER standards for integrity and objectivity.
Intelligent Web Crawling (WI-IAT 2013 Tutorial)Denis Shestakov
<<< Slides can be found at http://www.slideshare.net/denshe/intelligent-crawling-shestakovwiiat13 >>>
-------------------
Web crawling, a process of collecting web pages in
an automated manner, is the primary and ubiquitous operation used by a large number of web systems and agents starting from a simple program for website backup to a major web search engine. Due to an astronomical amount of data already published on the Web and ongoing exponential growth of web content, any party that want to take advantage of massive-scale web data faces a high barrier to entry. We start with background on web crawling and the structure of the Web. We then discuss different crawling strategies and describe adaptive web crawling techniques leading to better overall crawl performance. We finally overview some of the challenges in web crawling by presenting such topics as collaborative web crawling, crawling the deep Web and crawling multimedia content. Our goals are to introduce the intelligent systems community to the challenges in web crawling research, present intelligent web crawling approaches, and engage researchers and practitioners for open issues and research problems. Our presentation could be of interest to web intelligence and intelligent agent technology communities as it particularly focuses on the usage of intelligent/adaptive techniques in the web crawling domain.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. Web Scraping
Web scraping, web harvesting, or web data extraction is data
scraping used for extracting data from websites.
Web scraping software may access the World Wide Web directly
using the Hypertext Transfer Protocol, or through a web browser.
While web scraping can be done manually by a software user, the
term typically refers to automated processes implemented using
a bot or web crawler.
3. Web Scraping
It is a form of copying, in which specific data is gathered and copied
from the web, typically into a central local database or spreadsheet,
for later retrieval or analysis.
Scraping a web page involves fetching it and extracting data from it.
Fetching is the downloading of a page (which a browser does when
you view the page).
Therefore, web crawling is a main component of web scraping, to
fetch pages for later processing.
4. Web Scraping
Once fetched, the extraction can take place. The content of a page
may be parsed, searched, reformatted, its data copied into a
spreadsheet, and so on.
Web scrapers typically take something out of a page, to make use
of it for another purpose somewhere else.
An example would be to find and copy names and phone numbers,
or companies and their URLs, to a list (contact scraping).
5. Web Scraping
Web scraping is used as a component of applications for web
indexing, web mining and data mining, online price change
monitoring and price comparison, product review scraping (to watch
the competition), gathering real estate listings, weather data
monitoring, website change detection, research, tracking online
presence and reputation, web mashup and, web data integration.
Newer forms of web scraping involve listening to data feeds from
web servers. For example, JSON is commonly used as a transport
storage mechanism between the client and the web server.
9. Each year Forbes ranks the world based on a variety categories
ranging from the wealthiest people on the planet to the best
colleges America has to offer.
Forbes is the preeminent maintainer of covering a wide range of
business related topics including sports, entertainment, individual
wealth, and locations.
The lists are chocked full of data that can be analyzed, visualized
and merged with other data.
10. Upon discovering that Forbes
went to the pains of building an
API, even though it is
undocumented, Alex Bresler
decided to build forbesListR
package to wrap that API and
make it as easy as possible to
access data with a few simple
functions.
