Media Cloud
Media Cloud is an open-source content analysis tool that aims to map news media coverage of current events. It "performs five basic functions -- media definition, crawling, text extraction, word vectoring, and analysis."Media CloudAbout. Retrieved 2011-10-12 Media cloud "tracks hundreds of newspapers and thousands of Web sites and blogs, and archives the information in a searchable form. The database ... enable researchers to search for key people, places and events — from Michael Jackson to the Iranian elections — and find out precisely when, where and how frequently they are covered." Media Cloud was developed by the Berkman Center for Internet & Society at Harvard University and launched in March 2009. It's distributed under the GNU GPL 3+. As of October 2011, Media Cloud tracks news from mostly U.S. sources.

Data Analysis
Data analysis is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, and is used in different business, science, and social science domains. In today's business world, data analysis plays a role in making decisions more scientific and helping businesses operate more effectively. Data mining is a particular data analysis technique that focuses on statistical modeling and knowledge discovery for predictive rather than purely descriptive purposes, while business intelligence covers data analysis that relies heavily on aggregation, focusing mainly on business information. In statistical applications, data analysis can be divided into descriptive statistics, exploratory data analysis (EDA), and confirmatory data analysis (CDA). EDA focuses on discovering ne ...

Civic Engagement
Civic engagement or civic participation is any individual or group activity addressing issues of public concern. Civic engagement includes communities working together or individuals working alone in both political and non-political actions to protect public values or make a change in a community. The goal of civic engagement is to address public concerns and promote the quality of the community. Civic engagement is "a process in which people take collective action to address issues of public concern" and is "instrumental to democracy" (Checkoway & Aldana, 2012). Underrepresentation of groups in the government causes issues faced by groups such as minority, low-income, and younger groups to be overlooked or ignored. In turn, issues for higher voting groups are addressed more frequently, causing more bills to be passed to fix these problems (Griffin & Newman, 2008). Forms Civic engagement can take many forms—from individual volunteerism, community engagement efforts, organiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Center For Civic Media
The MIT Center for Civic Media (formerly the Center for Future Civic Media) was a research and practical center that developed and implemented tools that supported political action and "the information needs of iviccommunities". Its mission read in part: :The MIT Center for Civic Media creates and deploys technical and social tools that fill the information needs of communities. :We are inventors of new technologies that support and foster civic media and political action; we are a hub for the study of these technologies; and we coordinate community-based test beds both in the United States and internationally. At the end of August, 2020, the Center for Civic Media closed down. History The Center for Civic Media was founded in 2007 as a joint effort of the MIT Media Lab and the MIT Comparative Media Studies program. Its initial funding, a four-year grant from the Knight Foundation, was won in a contest "to foster blogs and other digital efforts that seek to bring together resi ...

Streaming Algorithm
In computer science, streaming algorithms are algorithms for processing data streams in which the input is presented as a sequence of items and can be examined in only a few passes (typically just one). In most models, these algorithms have access to limited memory (generally logarithmic in the size of and/or the maximum value in the stream). They may also have limited processing time per item. These constraints may mean that an algorithm produces an approximate answer based on a summary or "sketch" of the data stream. History Though streaming algorithms had already been studied by Munro and Paterson as early as 1978, as well as Philippe Flajolet and G. Nigel Martin in 1982/83, the field of streaming algorithms was first formalized and popularized in a 1996 paper by Noga Alon, Yossi Matias, and Mario Szegedy. For this paper, the authors later won the Gödel Prize in 2005 "for their foundational contribution to streaming algorithms." There has since been a large body of work cen ...

Web Crawling
A Web crawler, sometimes called a spider or spiderbot and often shortened to crawler, is an Internet bot that systematically browses the World Wide Web and that is typically operated by search engines for the purpose of Web indexing (''web spidering''). Web search engines and some other websites use Web crawling or spidering software to update their web content or indices of other sites' web content. Web crawlers copy pages for processing by a search engine, which indexes the downloaded pages so that users can search more efficiently. Crawlers consume resources on visited systems and often visit sites unprompted. Issues of schedule, load, and "politeness" come into play when large collections of pages are accessed. Mechanisms exist for public sites not wishing to be crawled to make this known to the crawling agent. For example, including a robots.txt file can request bots to index only parts of a website, or nothing at all. The number of Internet pages is extremely large; even ...

Gamergate Controversy
Gamergate or GamerGate (GG) was a loosely organized misogynistic online harassment campaign and a right-wing backlash against feminism, diversity, and progressivism in video game culture. It was conducted using the hashtag "#Gamergate" primarily in 2014 and 2015. Beginning in August 2014, Gamergate targeted women in the video game industry, most notably feminist media critic Anita Sarkeesian and video game developers Zoë Quinn and Brianna Wu, among others. The harassment campaign included doxing, rape threats, and death threats. Gamergate proponents ("Gamergaters") stated that they were a social movement, but lacked well-defined goals, a coherent message, and leaders, making Gamergate difficult to define. Gamergaters claimed to promote ethics in video games journalism, claimed to be protecting the "gamer" identity, and opposed what they asserted as " political correctness" in video games. Gamergaters created conspiracy theories falsely accusing Quinn of an unethical relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echo Chamber (media)
In discussions of news media, an echo chamber refers to situations in which beliefs are amplified or reinforced by communication and repetition inside a closed system and insulated from rebuttal. By participating in an echo chamber, people are able to seek out information that reinforces their existing views without encountering opposing views, potentially resulting in an unintended exercise in confirmation bias. Echo chambers may increase social and political polarization and extremism.Barberá, Pablo, et al. (21 August 2015)"Tweeting from left to right: Is online political communication more than an echo chamber?" ''Psychological Science''. 26.10: 1531-1542. On social media, it is thought that echo chambers limit exposure to diverse perspectives, and favour and reinforce presupposed narratives and ideologies. The term is a metaphor based on an acoustic echo chamber, in which sounds reverberate in a hollow enclosure. Another emerging term for this echoing and homogenizing effec ...

Confirmation Bias
Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for emotionally charged issues, and for deeply entrenched beliefs. Confirmation bias cannot be eliminated, but it can be managed, for example, by education and training in critical thinking skills. Biased search for information, biased interpretation of this information, and biased memory recall, have been invoked to explain four specific effects: # ''attitude polarization'' (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence) # ''belief perseverance'' (when beliefs persist after the evidence for them is shown to be false) # the ''irr ...

Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce st ...

RAMP Simulation Software For Modelling Reliability, Availability And Maintainability
RAMP Simulation Software for Modelling Reliability, Availability and Maintainability (RAM) is a computer software application developed by WS Atkins specifically for the assessment of the reliability, availability, maintainability and productivity characteristics of complex systems that would otherwise prove too difficult, cost too much or take too long to study analytically. The name RAMP is an acronym standing for Reliability, Availability and Maintainability of Process systems. RAMP models reliability using failure probability distributions for system elements, as well as accounting for common mode failures. RAMP models availability using logistic repair delays caused by shortages of spare parts or manpower, and their associated resource conditions defined for system elements. RAMP models maintainability using repair probability distributions for system elements, as well as preventive maintenance data and fixed logistic delays between failure detection and repair commenceme ...

Link Analysis
In network theory, link analysis is a data-analysis technique used to evaluate relationships (connections) between nodes. Relationships may be identified among various types of nodes (objects), including organizations, people and transactions. Link analysis has been used for investigation of criminal activity (fraud detection, counterterrorism, and intelligence), computer security analysis, search engine optimization, market research, medical research, and art. Knowledge discovery Knowledge discovery is an iterative and interactive process used to identify, analyze and visualize patterns in data. Network analysis, link analysis and social network analysis are all methods of knowledge discovery, each a corresponding subset of the prior method. Most knowledge discovery methods follow these steps (at the highest level): # Data processing # Transformation # Analysis # Visualization Data gathering and processing requires access to data and has several inherent issues, including in ...
