Web scraping

Web scraping
Web scraping, web harvesting, or web data extraction is data scraping used for extracting data from websites.[1] 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. 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. Web scraping a web page involves fetching it and extracting from it.[1][2] 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. Once fetched, then extraction can take place. Newer forms of web scraping involve listening to data feeds from web servers. History[edit] Techniques[edit] Human copy-and-paste[edit] Related:  Saved WikiGood Reads

Web search engine Software system that is designed to search for information on the World Wide Web The results of a search for the term "lunar eclipse" in a web-based image search engine A web search engine or Internet search engine is a software system that is designed to carry out web search (Internet search), which means to search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. History[edit] Internet search engines themselves predate the debut of the Web in December 1990. Prior to September 1993, the World Wide Web was entirely indexed by hand. By 2000, Yahoo! Approach[edit] Market share[edit] Europe[edit] [edit]

Words Aptly Spoken Quotes by Bob Moorehead “The paradox of our time in history is that we have taller buildings but shorter tempers, wider Freeways, but narrower viewpoints. We spend more, but have less, we buy more, but enjoy less. We have bigger houses and smaller families, more conveniences, but less time. We drink too much, smoke too much, spend too recklessly, laugh too little, drive too fast, get too angry, stay up too late, get up too tired, read too little, watch TV too much, and pray too seldom. We've learned how to make a living, but not a life. We've cleaned up the air, but polluted the soul. These are the times of fast foods and slow digestion, big men and small character, steep profits and shallow relationships. These are the days of two incomes but more divorce, fancier houses, but broken homes. Remember, to spend some time with your loved ones, because they are not going to be around forever. Remember, to say, "I love you" to your partner and your loved ones, but most of all mean it.

Web service A Web service is a method of communications between two electronic devices over a network. It is a software function provided at a network address over the web with the service always on as in the concept of utility computing. The W3C defines a Web service as: a software system designed to support interoperable machine-to-machine interaction over a network. The W3C also states: We can identify two major classes of Web services:REST-compliant Web services, in which the primary purpose of the service is to manipulate XML representations of Web resources using a uniform set of stateless operations; andArbitrary Web services, in which the service may expose an arbitrary set of operations.[2] Explanation[edit] Many organizations use multiple software systems for management. Different software might be built using different programming languages, and hence there is a need for a method of data exchange that doesn't depend upon a particular programming language.

Online analytical processing Online analytical processing, or OLAP (/ˈoʊlæp/), is an approach to answer multi-dimensional analytical (MDA) queries swiftly in computing.[1] OLAP is part of the broader category of business intelligence, which also encompasses relational databases, report writing and data mining.[2] Typical applications of OLAP include business reporting for sales, marketing, management reporting, business process management (BPM),[3] budgeting and forecasting, financial reporting and similar areas, with new applications emerging, such as agriculture.[4] The term OLAP was created as a slight modification of the traditional database term online transaction processing (OLTP).[5] OLAP tools enable users to analyze multidimensional data interactively from multiple perspectives. Overview of OLAP systems[edit] The cube metadata is typically created from a star schema or snowflake schema or fact constellation of tables in a relational database. For example: Multidimensional databases[edit] Aggregations[edit]

Web science Human behavior co-constituting the web. Web science is an emerging interdisciplinary field concerned with the study of large-scale socio-technical systems, particularly the World Wide Web.[1][2] It considers the relationship between people and technology, the ways that society and technology co-constitute one another and the impact of this co-constitution on broader society. Web Science combines research from disciplines as diverse as sociology, computer science, economics, and mathematics.[3] An earlier definition was given by American computer scientist Ben Shneiderman: "Web Science" is processing the information available on the web in similar terms to those applied to natural environment.[4] The Web Science Institute describes Web Science as focusing "the analytical power of researchers from disciplines as diverse as mathematics, sociology, economics, psychology, law and computer science to understand and explain the Web.

13 great books to help you succeed, create, & communicate better in 2013 Recently I read legendary filmmaker Akira Kurosawa's autobiography. One of the many things from his book that resonated with me was his strong belief that voracious reading was a key to his creativity. "I've forgotten who it was that said creation is memory," kurosawa said. "My own experiences and the various things I have read remain in my memory and become the basis upon which I create something new. Below are thirteen books—most of them quite new—that I have read recently which may appeal to professionals and students who desire making a bigger splash in the world or in their local communities by sharing their ideas with more clarity and lasting impact. by Chris Brogan and Julien Smith Your ideas can change the world, at least in a small way (and sometimes in a very big way).

Web literacy Web literacy comprises the skills and competencies needed for reading, writing and participating on the web.[1] It has been described as "both content and activity" – i.e., web users should not just learn about the web but also how to make their own website.[2] History of the concept[edit] In the latter part of the 1990s, literacy researchers started to explore the differences between printed text and the network-enabled devices with screens. Web Literacy Map[edit] The Mozilla Foundation is a non-profit organization that promotes openness, innovation and participation on the Internet. Literacy Version 1.1 of the Web Literacy Map was released in early 2014[10] and underpins the Mozilla Foundation's Webmaker resources section, where learners and mentors can find activities that help teach related areas.

Overcoming Perfectionism by Focusing on Excellence Instead “The important work of moving the world forward does not wait to be done by perfect men” – George Elliott We all know the feeling… We start a diet, and we stick to it PERFECTLY. Then suddenly temptation gets the better of us… …we eat ONE bad thing and BOOM. We binge like there’s no tomorrow and feel guilty. This is All Or Nothing Thinking, a classic symptom of perfectionism. But perfectionism doesn’t just affect our diets, it affects our confidence, our relationships, and our work… …and it needs to be stamped out. Why Learning From Failure Is ESSENTIAL In How To Overcome Procrastination And Turn Pro, I briefly explained that we often know what we should do in order to succeed, but often find the idea of following our own advice too frightening to act upon. If we fail under someone else’s council then surely it is not our competence that is questionable, but the council we have received. Good fortune is no longer a recognised compliment. The lesson? Even Plato Had Self Doubt All Or Nothing Thinking

Web intelligence Web intelligence is the area of scientific research and development that explores the roles and makes use of artificial intelligence and information technology for new products, services and frameworks that are empowered by the World Wide Web.[1] The term was coined in a paper written by Ning Zhong, Jiming Liu Yao and Y.Y. Ohsuga in the Computer Software and Applications Conference in 2000.[2] Research[edit] The research about the web intelligence covers many fields – including data mining (in particular web mining), information retrieval, pattern recognition, predictive analytics, the semantic web, web data warehousing – typically with a focus on web personalization and adaptive websites.[3] References[edit] ^ Zhong, Ning; Liu Yao, Jiming; Yao, Yiyu (2003).
