 Glossary 

Most of the descriptions for these terms are taken from Wikipedia.org

BOOKMARKED ITEM , ALSO KNOWN IN MELT AS AN ITEM PUT IN FAVOURITES
  • This is a website, a learning resource or any other digital object that the user has made a virtual link to by using a bookmarking service. Usually a bookmarked item is also given a keyword that facilitates its findability again.
BROAD FOLKSONOMY 
  • A collaborative tagging system where many people tag a few items (i.e. the scope of people tagging is “broad”).
CONTROLLED VOCABULARY 
  • Controlled vocabularies are used in indexing schemes, thesauri and taxonomies. These schemes mandate the uses of predefined, authorised terms that have been pre-selected by the designer of the controlled vocabulary.
EXPERT INDEXING
  • In MELT, indexing of resources can be done by two different groups: experts who are teachers or other professionals with profound knowledge of indexing, and by teachers. Expert indexing referrers to the first group.
FOLKSONOMY
  • A folksonomy is a user-generated metadata used to categorise and retrieve Web pages, photographs, Web links and other Web content using open-ended labels called tags. Typically, folksonomies are Internet-based. A well-developed folksonomy is ideally accessible as a shared vocabulary that is both originated by, and familiar to, its primary users.
METADATA
  • Metadata is "data about data." It can generally be thought of as information that describes, or supplements, the central data and helps its indexing and retrieval.
NARROW FOLKSONOMY
  • A collaborative tagging system where a few people tag items that they have created themselves (i.e. the scope of people tagging is “narrow”).
THE RT RELATIONSHIP, RELATED TERM, RT
  • A relationship between terms which are not members of an equivalence set; neither are subordinated or superordinated to another, but are mentally associated to such an extent that it is useful to make the link between them explicit. The RT relation is a not-hierarchical, mutual and symmetric relationship, that is: If A is a RT of B, then B is a RT of A.

SOCIAL BOOKMARKING
  • Social bookmarking is a web-based service to share Internet bookmarks and a popular way to store, classify, share and search links through the practice of folksonomy techniques on the Internet or Intranet.
SOCIAL SOFTWARE 
  • Social software is defined broadly as any web-based software tool that supports or fosters group interaction. It enables people to connect and collaborate through technology-mediated communication.(Wikipedia, March 2007). There are many genres of social software: communication tools, collaborative tools like groupware and wikis, and social network sites.
SOCIAL CONTENT 
  • Social Content is any information that people create about themselves to share with others such as preferences, blog postings, manifests of relationships.
SOCIAL CONTEXT 
  • Social context centres on a person's heterogeneous social networks; people are known to have a variety of networks. It can be used to explain the ways that applications attempt to create networks imitating the way real-life social protocols work.
TAG 
  • A type of metadata, generated by users and creators of the content, involving the association of descriptors with objects.
TAG CLOUD 
  • A weighted list in visual design, can be used as a visual depiction of content tags used on a website. More frequently used tags are depicted in a larger font or otherwise emphasised, while the displayed order is generally alphabetical. Thus, both finding a tag by alphabet and by popularity is possible. Selecting a single tag within a tag cloud will generally lead to a collection of items that are associated with that tag.
TAGGING, SOCIAL TAGGING, COLLABORATIVE TAGGING
  • Collaborative tagging is regarded as democratic folksonomy metadata generation, i.e. rather than an individual controlling the metadata or tags about an article or other content, metadata is generated by both the creator and consumers of the content.
  • See our page on examples of social tagging tools.
TAXONOMY
  • Taxonomy is the practice and science of taxonomic classification. Taxonomies, which are composed of taxonomic units known as taxa (singular taxon), are frequently hierarchical in structure, and commonly display parent-child relationships.
THESAURUS 
  • A thesaurus, which is designed for indexing is a list of every important term (single-word or multi-word) in a given domain of knowledge; and a set of related terms for each term in the list.
USE-UF, THE INTRA-LANGUAGE EQUIVALENCE
  • The intra-language equivalence is used in thesauri to facilitate the access to documents that were indexed by the documentalist differently from what the end-user may think. A descriptor, which is a thesaurus term, can have many non-descriptors, i.e. words related to it that help users who use free natural language to better search. etb.eun.org
VISUALIZATION
  • Visualization in MELT is used to describe a variety of techniques that use images, diagrams, or animations to display relations between resources, tags and people.
