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 artificial scarcity, 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, knowledg ...

Knowledge
Knowledge is an Declarative knowledge, awareness of facts, a Knowledge by acquaintance, familiarity with individuals and situations, or a Procedural knowledge, practical skill. Knowledge of facts, also called propositional knowledge, is often characterized as Truth, true belief that is distinct from opinion or guesswork by virtue of Justification (epistemology), justification. While there is wide agreement among philosophers that propositional knowledge is a form of true belief, many controversies focus on justification. This includes questions like how to understand justification, whether it is needed at all, and whether something else besides it is needed. These controversies intensified in the latter half of the 20th century due to a series of thought experiments called ''Gettier cases'' that provoked alternative definitions. Knowledge can be produced in many ways. The main source of empirical knowledge is perception, which involves the usage of the senses to learn about ...

Google Answers
Google Answers was an online knowledge market offered by Google, active from April 2002 until December 2006. History Google Answers' predecessor was Google Questions and Answers, which was launched in June 2001. This service involved Google staffers answering questions by e-mail for a flat fee (US$3.00). It was fully functional for about 24 hours, after which it was shut down, possibly due to excessive demand and the tough competition that Yahoo! set in place. Google Answers was launched in April 2002. A month later, a search feature was added. Google Answers came out of beta in May 2003. It received more than 100 question postings per day when the service ended in December 2006. According to Danny Sullivan of Searchenginewatch, Google Answers was not solid enough to compete against Yahoo! Answers. In late November 2006, Google reported that it planned to permanently shut down the service (except for the Hong Kong and Arabic versions). No new questions were accepted after ...

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/full text databases, or simply factual information drawn from the library's print or online reference c ...

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 21, 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 on May 4, 2021. The URL now redirects to the Yahoo! homepage. An unaffiliated Japanese version remains online. History The website Yahoo! was officially incorporated on Marc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

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.
