Microwork
Microwork is a series of many small tasks which together comprise a large unified project, and it is completed by many people over the Internet. Microwork is considered the smallest unit of work in a virtual assembly line. It is most often used to describe tasks for which no efficient algorithm has been devised, and require human intelligence to complete reliably. The term was developed in 2008 by Leila Chirayath Janah of Samasource. Microtasking Microtasking is the process of splitting a large job into small tasks that can be distributed, over the Internet, to many people. This work is often believed to be Since the inception of microwork, many online services have been developed that specialize in different types of microtasking. Most of them rely on a large, voluntary workforce composed of Internet users from around the world. Typical tasks offered are repetitive but not so simple that they can be automated. Good candidates for microtasks have the following characteristics: * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crowdsourcing
Crowdsourcing involves a large group of dispersed participants contributing or producing goods or services—including ideas, votes, micro-tasks, and finances—for payment or as volunteers. Contemporary crowdsourcing often involves digital platforms to attract and divide work between participants to achieve a cumulative result. Crowdsourcing is not limited to online activity, however, and there are various historical examples of crowdsourcing. The word crowdsourcing is a portmanteau of " crowd" and " outsourcing". In contrast to outsourcing, crowdsourcing usually involves less specific and more public groups of participants. Advantages of using crowdsourcing include lowered costs, improved speed, improved quality, increased flexibility, and/or increased scalability of the work, as well as promoting diversity. Crowdsourcing methods include competitions, virtual labor markets, open online collaboration and data donation. Some forms of crowdsourcing, such as in "idea compe ...

Amazon Mechanical Turk
Amazon Mechanical Turk (MTurk) is a crowdsourcing website for businesses to hire remotely located "crowdworkers" to perform discrete on-demand tasks that computers are currently unable to do. It is operated under Amazon Web Services, and is owned by Amazon. Employers (known as ''requesters'') post jobs known as ''Human Intelligence Tasks'' (HITs), such as identifying specific content in an image or video, writing product descriptions, or answering survey questions. Workers, colloquially known as ''Turkers'' or ''crowdworkers'', browse among existing jobs and complete them in exchange for a fee set by the employer. To place jobs, the requesting programs use an open application programming interface (API), or the more limited MTurk Requester site. As of April 2019, Requesters could register from 49 approved countries. History The service was conceived by Venky Harinarayan in a US patent disclosure in 2001.Multiple sources: * * Amazon coined the term ''artificial artificial intell ...

Human-based Computation
Human-based computation (HBC), human-assisted computation, ubiquitous human computing or distributed thinking (by analogy to distributed computing) is a computer science technique in which a machine performs its function by outsourcing certain steps to humans, usually as microwork. This approach uses differences in abilities and alternative costs between humans and computer agents to achieve symbiotic human–computer interaction. For computationally difficult tasks such as image recognition, human-based computation plays a central role in training Deep Learning-based Artificial Intelligence systems. In this case, human-based computation has been referred to as human-aided artificial intelligence. In traditional computation, a human employs a computer to solve a problem; a human provides a formalized problem description and an algorithm to a computer, and receives a solution to interpret. Human-based computation frequently reverses the roles; the computer asks a person or a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

She was the daughter of Indian immigrants, who came to the United States with nothing. Janah described her childhood as being difficult, often due to a lack of financial security. As a teenager, Janah worked many jobs, including babysitting and tutoring..She attended the California Academy of Mathematics and Science. She won a scholarship at 17 through American Field Services, and convinced them to let her spend it teaching in Ghana where she spent 6 months during her senior year of high school. In Ghana, Janah taught English to young students in the village ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrotasking
Macrotasking is a type of crowdsourcing that is distinct from microtasking. Macrotasks typically have the following characteristics: *they can be done independently *they take a fixed amount of time *they require special skills Microtasking projects can also be small pieces of a much larger whole, which workers never see, while macrotasks could be part of a large, visible project where workers pitch in wherever they have the required skills. A macrotask might be the creation of an analytical paper or a video, or the pursuit of a contest like the Netflix Prize The Netflix Prize was an open competition for the best collaborative filtering algorithm to predict user ratings for films, based on previous ratings without any other information about the users or films, i.e. without the users being identified e ..., while a microtask could include the editing of a document for grammar or transcription of a video. A number of sites connect people with freelancers who can fulfill macrota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toloka
Toloka is a crowdsourcing platform and microtasking project launched by Yandex in 2014 to quickly markup large amounts of data, which are then used for machine learning and improving search algorithms. The proposed tasks are usually simple and do not require any special training from the performer. Most of the tasks are designed to improve algorithms that are used by modern technologies spanning self-driving vehicles, smart web searches, advanced voice assistants and e-commerce. Upon completion of each task the performer receives a reward based on the volume of images, videos, and unstructured text. The service has two app versions – for Android and iOS. About Toloka Origin of the platform's name A toloka used to be a form of mutual assistance among villagers of Russia, Ukraine, Belarus, Estonia, Latvia, and Lithuania. It was organized in villages to perform urgent work requiring a large number of workers, such as harvesting, logging, building houses, etc. Sometime ...

Galaxy Zoo
Galaxy Zoo is a crowdsourced astronomy project which invites people to assist in the morphological classification of large numbers of galaxies. It is an example of citizen science as it enlists the help of members of the public to help in scientific research. There have been 15 versions as of July 2017. Galaxy Zoo is part of the Zooniverse, a group of citizen science projects. An outcome of the project is to better determine the different aspects of objects and to separate them into classifications. Origins A key factor leading to the creation of the project was the problem of what has been referred to as data deluge, where research produces vast sets of information to the extent that research teams are not able to analyse and process much of it. Kevin Schawinski, previously an astrophysicist at Oxford University and co-founder of Galaxy Zoo, described the problem that led to Galaxy Zoo's creation when he was set the task of classifying the morphology of more than 900,0 ...

Galaxies
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek ' (), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy's center of mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies. Galaxies are categorized according to their visual morphology as elliptical, spiral, or irregular. Many are thought to have supermassive black holes at their centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the S ...

CCTV
Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring ( Videotelephony is seldom called "CCTV"). Surveillance of the public using CCTV is common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance, often used in law enforcement, with cameras located on a police officer's chest or head. Video surveillance has generated significant debate about balancing its use with individuals' right to privacy even when in publi ...

Web Traffic
Web traffic is the data sent and received by visitors to a website. Since the mid-1990s, web traffic has been the largest portion of Internet traffic. Sites monitor the incoming and outgoing traffic to see which parts or pages of their site are popular and if there are any apparent trends, such as one specific page being viewed mostly by people in a particular country. There are many ways to monitor this traffic, and the gathered data is used to help structure sites, highlight security problems or indicate a potential lack of bandwidth. Not all web traffic is welcomed. Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. Sites also often aim to increase their web traffic through inclusion on search engines and through search engine optimization. Analysis Web analytics is the measurement of the behavior of visitors to a website. In a commercial context, it especially refers to the measurement of whi ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm can be expressed within a finite amount of sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
