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 except by numbers assigned for the contest. The competition was held by Netflix, an online DVD-rental and video streaming service, and was open to anyone who is neither connected with Netflix (current and former employees, agents, close relatives of Netflix employees, etc.) nor a resident of certain blocked countries (such as Cuba or North Korea). On September 21, 2009, the grand prize of was given to the BellKor's Pragmatic Chaos team which bested Netflix's own algorithm for predicting ratings by 10.06%. Problem and data sets Netflix provided a ''training'' data set of 100,480,507 ratings that 480,189 users gave to 17,770 movies. Each training rating is a quadruplet of the form .

Inducement Prize Contest
An inducement prize contest (IPC) is a competition that awards a cash prize for the accomplishment of a feat, usually of engineering. IPCs are typically designed to extend the limits of human ability. Some of the most famous IPCs include the Longitude prize (1714–1765), the Orteig Prize (1919–1927) and the prizes from the X Prize Foundation. IPCs are distinct from recognition prizes, such as the Nobel Prize, in that IPCs have prospectively defined criteria for what feat is to be achieved for winning the prize, while recognition prizes may be based on the beneficial effects of the feat. History Throughout history, there have been instances where IPCs were successfully utilized to push the boundaries of what would have been considered state-of-the-art at the time. The Longitude Prize was a reward offered by the British government for a simple and practical method for the precise determination of a ship's longitude. The prize, established through an Act of Parliament (the Long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Innovation Competition
An innovation competition is a method or process of the industrial process, product or business development. It is a form of social engineering, which focuses to the creation and elaboration of the best and sustainable ideas, coming from the best innovators. Innovation competition research There are few major works, like Terwiesch and Ulrich, who exclusively focus on innovation competitions. They argue, that while innovation is seen as a largely creative endeavor, it can also be rigorously managed by viewing and structuring the innovation process as a collection of “opportunities”. Profitable innovation comes not from increasing investments in R&D, but from systematically identifying more exceptional opportunities. Terwiesch and Ulrich show how to design and run innovation tournaments: pitting competing opportunities against one another, and then consistently filtering out the weakest ones until only those with the highest profit potential remain. The aims and the design pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Innovation
Open innovation is a term used to promote an information age mindset toward innovation that runs counter to the secrecy and silo mentality of traditional corporate research labs. The benefits and driving forces behind increased openness have been noted and discussed as far back as the 1960s, especially as it pertains to interfirm cooperation in R&D. Use of the term 'open innovation' in reference to the increasing embrace of external cooperation in a complex world has been promoted in particular by Henry Chesbrough, adjunct professor and faculty director of the Center for Open Innovation of the Haas School of Business at the University of California, and Maire Tecnimont Chair of Open Innovation at Luiss. The term was originally referred to as "a paradigm that assumes that firms can and should use external ideas as well as internal ideas, and internal and external paths to market, as the firms look to advance their technology". More recently, it is defined as "a distributed innova ... [...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 competiti ...

Privacy For Research Participants
Privacy for research participants is a concept in research ethics which states that a person in human subject research has a right to privacy when participating in research. Some typical scenarios this would apply to include, or example, a surveyor doing social research conducts an interview with a participant, or a medical researcher in a clinical trial asks for a blood sample from a participant to see if there is a relationship between something which can be measured in blood and a person's health. In both cases, the ideal outcome is that any participant can join the study and neither the researcher nor the study design nor the publication of the study results would ever identify any participant in the study. Thus, the privacy rights of these individuals can be preserved. Privacy for medical research participants is protected by several procedures such as informed consent, compliance with medical privacy laws, and transparency in how patient data is accumulated and analyzed.

Video Privacy Protection Act
The Video Privacy Protection Act (VPPA) is a bill that was passed by the United States Congress in 1988 as and signed into law by President Ronald Reagan. It was created to prevent what it refers to as "wrongful disclosure of video tape rental or sale records r similar audio visual materials, to cover items such as video games and the future DVD">video_games.html" ;"title="r similar audio visual materials, to cover items such as video games">r similar audio visual materials, to cover items such as video games and the future DVD format]." Congress passed the VPPA after Robert Bork's video rental history was published during Robert Bork Supreme Court nomination, his Supreme Court nomination. It makes any "video tape service provider" that discloses rental information outside the ordinary course of business liable for up to $2500 in actual damages. Computer-based VPPA litigation Prior to 2007, VPPA had not been cited by privacy attorneys as a cause of action involving computin ...

Fair Trade
Fair trade is an arrangement designed to help producers in developing countries achieve sustainable and equitable trade relationships. The fair trade movement combines the payment of higher prices to exporters with improved social and environmental standards. The movement focuses in particular on commodities, or products that are typically exported from developing countries to developed countries but is also used in domestic markets (e.g., Brazil, the United Kingdom and Bangladesh), most notably for handicrafts, coffee, cocoa, wine, sugar, fruit, flowers and gold. Fair trade labelling organizations commonly use a definition of ''fair trade'' developed by FINE, an informal association of four international fair trade networks: Fairtrade Labelling Organizations International, World Fair Trade Organization (WFTO), Network of European Worldshops and European Fair Trade Association (EFTA). Fair trade, by this definition, is a trading partnership based on dialogue, transparency a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class Action Lawsuit
A class action, also known as a class-action lawsuit, class suit, or representative action, is a type of lawsuit where one of the parties is a group of people who are represented collectively by a member or members of that group. The class action originated in the United States and is still predominantly a US phenomenon, but Canada, as well as several European countries with civil law, have made changes in recent years to allow consumer organizations to bring claims on behalf of consumers. Description In a typical class action, a plaintiff sues a defendant or a number of defendants on behalf of a group, or class, of absent parties. This differs from a traditional lawsuit, where one party sues another party, and all of the parties are present in court. Although standards differ between states and countries, class actions are most common where the allegations usually involve at least 40 people who the same defendant has injured in the same way. Instead of each damaged person bring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
