Reputation Systems
Reputation systems are programs or algorithms that allow users to rate each other in online communities in order to build trust through reputation. Some common uses of these systems can be found on E-commerce websites such as eBay, Amazon.com, and Etsy as well as online advice communities such as Stack Exchange. These reputation systems represent a significant trend in "decision support for Internet mediated service provisions". With the popularity of online communities for shopping, advice, and exchange of other important information, reputation systems are becoming vitally important to the online experience. The idea of reputation systems is that even if the consumer can't physically try a product or service, or see the person providing information, that they can be confident in the outcome of the exchange through trust built by recommender systems. Collaborative filtering, used most commonly in recommender systems, are related to reputation systems in that they both collect rati ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific Computational problem, 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 (computer science), 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 ca ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Brick And Mortar Store
Brick and mortar (also bricks and mortar or B&M) refers to a physical presence of an organization or business in a building or other structure. The term ''brick-and-mortar business'' is often used to refer to a company that possesses or leases retail shops, factory production facilities, or warehouses for its operations. More specifically, in the jargon of e-commerce businesses in the 2000s, brick-and-mortar businesses are companies that have a physical presence (e.g., a retail shop in a building) and offer face-to-face customer experiences. This term is usually used to contrast with a transitory business or an Internet-only presence, such as fully online shops, which have no physical presence for shoppers to visit, talk with staff in person, touch and handle products and buy from the firm in person. However, such online businesses normally have non-public physical facilities from which they either run business operations (e.g., the company headquarters and back office facilitie ...

TrustedSource
TrustedSource is an Internet reputation system originally developed by CipherTrust and now owned by Intel Security. It provides reputation scores for Internet identities, such as IP addresses, URLs, domains, and email/web content. Reputation data and content categories, as well as global email, web and other network traffic patterns observed by TrustedSource ecosystem, for any IP address, domain, or URL can be checked from the TrustedSource.org portal site TrustedSource works by analyzing in real-time traffic patterns from email, web and network data flows from McAfee's global set of security appliances and hosted services, as well as those of partners like F5 Networks. Working off that data stream, it applies data mining and analysis techniques, such as Support Vector Machine, Random forest Random forests or random decision forests is an ensemble learning method for classification, regression and other tasks that operates by constructing a multitude of decision tr ...

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.

Freelance Marketplace
''Freelance'' (sometimes spelled ''free-lance'' or ''free lance''), ''freelancer'', or ''freelance worker'', are terms commonly used for a person who is self-employed and not necessarily committed to a particular employer long-term. Freelance workers are sometimes represented by a company or a temporary agency that resells freelance labor to clients; others work independently or use professional associations or websites to get work. While the term ''independent contractor'' would be used in a different register of English to designate the tax and employment classes of this type of worker, the term "freelancing" is most common in culture and creative industries, and use of this term may indicate participation therein. Fields, professions, and industries where freelancing is predominant include: music, writing, acting, computer programming, web design, graphic design, translating and illustrating, film and video production, and other forms of piece work that some cultural theor ...

Advogato
Advogato was an online community and social networking site dedicated to free software development and created by Raph Levien. In 2007, Steve Rainwater took over maintenance and new development from Raph. In 2016, Rainwater's running instance was shut down and backed up to archive.org. History Advogato described itself as "the free software developer's advocate." Advogato was an early pioneer of blogs, formerly known as "online diaries", and one of the earliest social networking websites. Advogato combined the most recent entries from each user's diary together into a single continuous feed called the ''recentlog'', directly inspiring the creation of the Planet aggregator somewhat later. Several high-profile members of the free software and open source software movements were users of the site, including Richard M. Stallman, Eric Raymond, Alan Cox, Bruce Perens, and Jamie Zawinski. Because Advogato was the first website to use a robust, attack-resistant trust metric and to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Imgur
Imgur ( , stylized as imgur) is an American online image sharing and image hosting service with a focus on social gossip that was founded by Alan Schaaf in 2009. The service has hosted viral images and meme, particularly those posted on Reddit. History The company was started in 2009 in Athens, Ohio as Alan Schaaf's side project while he attended Ohio University for computer science. Imgur was created as a response to the usability problems encountered in similar services. "It took off almost instantly, jumping from a thousand hits per day to a million total page views in the first five months." In October 2012, Imgur expanded its functionality to allow users to directly share images to Imgur instead of requiring images to gain enough attraction through other social media sites like Reddit to show up on the popular image gallery. In the beginning, Imgur relied on donations to help with the web hosting costs. Display ads were introduced in May 2009; sponsored images and self-se ...

Digg
Digg, stylized in lowercase as digg, is an American news aggregator with a curated front page, aiming to select stories specifically for the Internet audience such as science, trending political issues, and viral Internet issues. It was launched in its current form on July 31, 2012, with support for sharing content to other social platforms such as Twitter and Facebook. It formerly had been a popular social news website, allowing people to vote web content up or down, called ''digging'' and ''burying'', respectively. In 2012, Quantcast estimated Digg's monthly U.S. unique visits at 3.8 million. Digg's popularity prompted the creation of similar sites such as Reddit. In July 2008, the former company took part in advanced acquisition talks with Google for a reported $200 million price tag, but the deal ultimately fell through. After a controversial 2010 redesign and the departure of co-founders Jay Adelson and Kevin Rose, in July 2012 Digg was sold in three parts: the Digg brand ...

Reddit
Reddit (; stylized in all lowercase as reddit) is an American social news aggregation, content rating, and discussion website. Registered users (commonly referred to as "Redditors") submit content to the site such as links, text posts, images, and videos, which are then voted up or down by other members. Posts are organized by subject into user-created boards called "communities" or "subreddits". Submissions with more upvotes appear towards the top of their subreddit and, if they receive enough upvotes, ultimately on the site's front page. Reddit administrators moderate the communities. Moderation is also conducted by community-specific moderators, who are not Reddit employees. As of March 2022, Reddit ranks as the 9th- most-visited website in the world and 6th most-visited website in the U.S., according to Semrush. About 42–49.3% of its user base comes from the United States, followed by the United Kingdom at 7.9–8.2% and Canada at 5.2–7.8%. Twenty-two percent of U.S. ...
