Internet-based Knowledge Exchange
A knowledge market is a mechanism for distributing knowledge resources. There are two views on knowledge and how knowledge markets can function. One view uses a legal construct of intellectual property to make knowledge a typical scarce resource, so the traditional commodity market mechanism can be applied directly to distribute it. An alternative model is based on treating knowledge as a public good and hence encouraging free sharing of knowledge. This is often referred to as attention economy. Currently there is no consensus among researchers on relative merits of these two approaches. History A knowledge economy include the concept of exchanging knowledge-based products and services. However, as discussed by Stewart (1996) knowledge is very different from physical products. For example, it can be in more than one place at one time, selling it does not diminish the supply, buyers only purchase it once, and once sold, it cannot be recalled. Further, knowledge begets more knowle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knowledge
Knowledge can be defined as awareness of facts or as practical skills, and may also refer to familiarity with objects or situations. Knowledge of facts, also called propositional knowledge, is often defined as true belief that is distinct from opinion or guesswork by virtue of justification. While there is wide agreement among philosophers that propositional knowledge is a form of true belief, many controversies in philosophy focus on justification: whether it is needed at all, how to understand it, and whether something else besides it is needed. These controversies intensified due to a series of thought experiments by Edmund Gettier and have provoked various alternative definitions. Some of them deny that justification is necessary and replace it, for example, with reliability or the manifestation of cognitive virtues. Others contend that justification is needed but formulate additional requirements, for example, that no defeaters of the belief are present or that the ...

Reference Desk
The reference desk or information desk of a library is a public service counter where professional librarians provide library users with direction to library materials, advice on library collections and services, and expertise on multiple kinds of information from multiple sources. Purpose and usage Library users can consult the staff at the reference desk for help in finding information. Using a structured reference interview, the librarian works with the library user to clarify their needs and determine what information sources will fill them. To borrow a medical analogy, reference librarians diagnose and treat information deficiencies. The ultimate help provided may consist of reading material in the form of a book or journal article, instruction in the use of specific searchable information resources such as the library's online catalog or subscription bibliographic/fulltext databases, or simply factual information drawn from the library's print or online reference coll ...

Windows Live QnA
MSN QnA (formerly ''Live Search QnA'' and ''Windows Live QnA'', codenamed ''Answers''), was a question and answer service, part of Microsoft's MSN group of services. It is somewhat similar to Google Answers, but closer in function to Yahoo! Answers. Users could ask questions, tag them according to topic, and gain points and reputation for answering other users' questions. The service was community based; questions are posed to the whole community, rather than just one researcher. At this point there are apparently no plans for any monetary compensation of any kind for answering questions; rather, like with Yahoo! Answers, the only rewards are having high point counts and good reputation. In order to open an account a user needs a Windows Live ID (now Microsoft account). All questions on MSN QnA were "tagged" by the poster to allow easy searching and navigation. The MSN QnA beta ended and the website closed on May 21st, 2009.

Yahoo! Answers
Yahoo! Answers was a community-driven question-and-answer (Q&A) website or knowledge market owned by Yahoo! where users would ask questions and answer those submitted by others, and upvote them to increase their visibility. Questions were organised into categories with multiple sub-categories under each to cover every topic users may ask questions on, such as beauty, business, finance, cars, electronics, entertainment, games, gardening, science, news, politics, parenting, pregnancy, and travel. The number of poorly formed questions and inaccurate answers made the site a target of ridicule. On April 5, 2021, Yahoo! announced that Yahoo! Answers would be shutting down. On April 20, 2021, the website switched to read-only and users were no longer able to ask or answer questions. The site ceased operations in most languages on May 4, 2021; though the Japanese version remains online.

Stack Exchange
Stack Exchange is a network of question-and-answer (Q&A) websites on topics in diverse fields, each site covering a specific topic, where questions, answers, and users are subject to a reputation award process. The reputation system allows the sites to be self-moderating. As of August 2019, the three most actively-viewed sites in the network are Stack Overflow, Super User, and Ask Ubuntu. All sites in the network are modeled after the initial site Stack Overflow, a Q&A site for computer programming questions created by Jeff Atwood and Joel Spolsky. Further Q&A sites in the network are established, defined and eventually if found relevant brought to creation by registered users through a special site named Area 51.

Stack Overflow
In software, a stack overflow occurs if the call stack pointer exceeds the stack bound. The call stack may consist of a limited amount of address space, often determined at the start of the program. The size of the call stack depends on many factors, including the programming language, machine architecture, multi-threading, and amount of available memory. When a program attempts to use more space than is available on the call stack (that is, when it attempts to access memory beyond the call stack's bounds, which is essentially a buffer overflow), the stack is said to ''overflow'', typically resulting in a program crash. Causes Infinite recursion The most-common cause of stack overflow is excessively deep or infinite recursion, in which a function calls itself so many times that the space needed to store the variables and information associated with each call is more than can fit on the stack.

History Founding and naming Quora was co-founded by former Facebook employees Adam D'Angelo and Charlie Cheever in June 2009. In an answer to the question "How did Adam D'Angelo and Charlie Cheever come up with the name Quora?" written on Quora in 2011, Charlie Cheever stated, "We spent a few hours brainstorming and writing down all the ideas that we could think of. After consulting with friends and eliminating ones we didn't love, we narrowed it down to 5 or 6 finalists, and eventually settled on Quora." Cheever went on to state, "The closest competition that he nameQuora had was Quiver." 2010–2013: Early growth In March 2010, Q ...

Aardvark (search Engine)
Aardvark was a social search service that connected users live with friends or friends-of-friends who were able to answer their questions, also known as a knowledge market. Users submitted questions via the Aardvark website, email or instant messenger and Aardvark identified and facilitated a live chat or email conversation with one or more topic experts in the 'askers' extended social network. Aardvark was used for asking subjective questions for which human judgment or recommendation was desired. It was also used extensively for technical support questions. Users could also review question and answer history and other settings on the Aardvark website. Google acquired Aardvark for $50 million on February 11, 2010. In September 2011, Google announced it would discontinue a number of its products, including Aardvark.
