Symbolic artificial intelligenceIn artificial intelligence, symbolic artificial intelligence is the term for the collection of all methods in artificial intelligence research that are based on high-level symbolic (human-readable) representations of problems, logic and search. Symbolic AI used tools such as logic programming, production rules, semantic nets and frames, and it developed applications such as knowledge-based systems (in particular, expert systems), symbolic mathematics, automated theorem provers, ontologies, the semantic web, and automated planning and scheduling systems.
InstagramInstagram is a photo and video sharing social networking service owned by American company Meta Platforms. The app allows users to upload media that can be edited with filters, be organized by hashtags, and be associated with a location — via geographical tagging. Posts can be shared publicly or with preapproved followers. Users can browse other users' content by tags and locations, view trending content, like photos, and follow other users to add their content to a personal feed.
FolksonomyFolksonomy is a classification system in which end users apply public tags to online items, typically to make those items easier for themselves or others to find later. Over time, this can give rise to a classification system based on those tags and how often they are applied or searched for, in contrast to a taxonomic classification designed by the owners of the content and specified when it is published. This practice is also known as collaborative tagging, social classification, social indexing, and social tagging.
Tag cloudA tag cloud (also known as a word cloud, wordle or weighted list in visual design) is a visual representation of text data which is often used to depict keyword metadata on websites, or to visualize free form text. Tags are usually single words, and the importance of each tag is shown with font size or color. When used as website navigation aids, the terms are hyperlinked to items associated with the tag. In the language of visual design, a tag cloud (or word cloud) is one kind of "weighted list", as commonly used on geographic maps to represent the relative size of cities in terms of relative typeface size.
Remix cultureRemix culture, sometimes read-write culture, is a term describing a society that allows and encourages derivative works by combining or editing existing materials to produce a new creative work or product. A remix culture would be, by default, permissive of efforts to improve upon, change, integrate, or otherwise remix the work of creators and copyright holders, with or without their permission.
Non-negative matrix factorizationNon-negative matrix factorization (NMF or NNMF), also non-negative matrix approximation is a group of algorithms in multivariate analysis and linear algebra where a matrix V is factorized into (usually) two matrices W and H, with the property that all three matrices have no negative elements. This non-negativity makes the resulting matrices easier to inspect. Also, in applications such as processing of audio spectrograms or muscular activity, non-negativity is inherent to the data being considered.
Advocacy groupAdvocacy groups, also known as interest groups, special interest groups, lobbying groups, pressure groups, or public associations use various forms of advocacy and/or lobbying in order to influence public opinion and ultimately public policy. They play an important role in the development of political and social systems. Motives for action may be based on political, economic, religious, moral, commercial or common good-based positions.
Internet manipulationInternet manipulation refers to the co-optation of digital technology, such as social media algorithms and automated scripts, for commercial, social, or political purposes. Such tactics may be employed with the explicit intent to manipulate public opinion, polarise citizens, silence political dissidents, harm corporate or political adversaries and improve personal or brand reputation. Hackers, hired professionals and private citizens have all been reported to engage in internet manipulation using software - typically Internet bots such as social bots, votebots and clickbots.
