thesaurus

A thesaurus is a reference work that lists words grouped together according to similarity of meaning (containing synonyms and sometimes antonyms), in contrast to a dictionary, which contains definitions and pronunciations. In Information Science, Library Science, and Information Technology, specialized thesauri are designed for information retrieval. They are a type of controlled vocabulary, for indexing or tagging purposes. Such a thesaurus can be used as the basis of an index for online material. The Art and Architecture Thesaurus, for example, is used to index the Canadian Information retrieval thesauri are formally organized so that existing relationships between concepts are made explicit. As a result, they are more complex than simpler controlled vocabularies such as authority lists and synonym rings. Each term is placed in context, allowing a user to distinguish between "bureau" the office and "bureau" the furniture. Following international standards, they are generally arranged hierarchically by themes, topics or facets. Unlike a literary thesaurus, these specialized thesauri typically focus on one discipline, subject or field of study. In information technology, a thesaurus represents a database or list of semantically orthogonal topical search keys. In the field of Artificial Intelligence, a thesaurus may sometimes be referred to as an ontology. (Excerpt from Wikipedia article: Thesaurus)

udc

The Universal Decimal Classification is a system of library classification developed by the Belgian bibliographers Paul Otlet and Henri La Fontaine at the end of the 19th century. It is based on the Dewey Decimal Classification, but uses auxiliary signs to indicate various special aspects of a subject and relationships between subjects. It thus contains a significant faceted or analytico-synthetic element, and is used especially in specialist libraries. UDC has been modified and extended through the years to cope with the increasing output in all disciplines of human knowledge, and is still under continuous review to take account of new developments. The documents classified by UDC may be in any form. They will often be literature, i.e. written documents, but may also be in other media such as films, video and sound recordings, illustrations, maps, and realia such as museum pieces.

ukoer

Open educational resources (OER) are "digitised materials offered freely and openly for educators, students and self-learners to use and reuse for teaching, learning and research." Being a production and dissemination mode, OER are not involved in awarding degrees nor in providing academic or administrative support to students. However, OER materials are beginning to get integrated into open and distance education. Some OER producers have involved themselves in social media to increase their content visibility and reputation. OER include different kinds of digital assets. Learning content includes courses, course materials, content modules, learning objects, collections, and journals. Tools include software that supports the creation, delivery, use and improvement of open learning content, searching and organization of content, content and learning management systems, content development tools, and on-line learning communities. Implementation resources include intellectual property licenses that govern open publishing of materials, design-principles, and localization of content. They also include materials on best practices such as stories, publication, techniques, methods, processes, incentives, and distribution. (Excerpt from Wikipedia article: Open Educational Resources)

ulan

The Union List of Artist Names (ULAN) is a controlled vocabulary currently containing around 293,000 names and other information about artists. Names in ULAN may include given names, pseudonyms, variant spellings, names in multiple languages, and names that have changed over time (e.g., married names). Among these names, one is flagged as the preferred name. Although it is displayed as a list, ULAN is structured as a thesaurus, compliant with ISO and NISO standards for thesaurus construction; it contains hierarchical, equivalence, and associative relationships. The focus of each ULAN record is an artist. Currently there are around 120,000 artists in the ULAN. In the database, each artist record (also called a subject in this manual) is identified by a unique numeric ID. Linked to each artist record are names, related artists, sources for the data, and notes. The temporal coverage of the ULAN ranges from Antiquity to the present and the scope is global.

ulcc

The University of London Computer Centre (ULCC) was founded in 1968, and was the first supercomputer facility established in London for the purpose of scientific and educational research by all of the colleges of the University of London. ULCC initially provided large-scale CDC-based facilities, then from 1982 to 1991 a national Cray vector supercomputing service, and, latterly, a 6 processor, 4 Gbyte Convex C3860 supercomputer with a Convex C3200 front-end. ULCC also became a major site for national and international network connections in the UK. It ran the Network Operations and Service Centre for the JANET Internet Protocol Service (JIPS) (the largest of the JANET network centres) and various international links and relays on behalf of UKERNA. Since the closure of its supercomputer service in the 1990s, ULCC has focused on providing IT services across the educational and public sector, as well as undertaking research work in fields such as digital preservation and e-learning.

urn

A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme, and does not imply availability of the identified resource. Both URNs (names) and URLs (locators) are URIs, and a particular URI may be a name and a locator at the same time. The Functional Requirements for Uniform Resource Names are described in RFC 1737. The URNs are part of a larger Internet information architecture which is composed of URNs, Uniform Resource Characteristics (URCs), and Uniform Resource Locators (URLs). Each plays a specific role: URNs are used for identification; URCs for including meta-information; URLs for locating or finding resources. (Excerpt from Wikipedia article: Uniform Resource Name)

usb

Universal Serial Bus (USB) is a specification to establish communication between devices and a host controller (usually a personal computer), developed and invented by Ajay Bhatt, while working for Intel. USB has effectively replaced a variety of interfaces such as serial and parallel ports. USB can connect computer peripherals such as mice, keyboards, digital cameras, printers, personal media players, flash drives, Network Adapters, and external hard drives. For many of those devices, USB has become the standard connection method. USB was designed for personal computers, but it has become commonplace on other devices such as smartphones, PDAs and video game consoles, and as a power cord.

utf-8

UTF-8 (UCS Transformation Format - 8-bit) is a multibyte character encoding for Unicode. UTF-8 is like UTF-16 and UTF-32, because it can represent every character in the Unicode character set. But unlike UTF-16 and UTF-32, it possesses the advantages of being backward-compatible with ASCII. And it has the advantage of avoiding the complications of endianness and the resulting need to use byte order marks (BOM). For these and other reasons, UTF-8 has become the dominant character encoding for the World-Wide Web, accounting for more than half of all Web pages. The Internet Engineering Task Force (IETF) requires all Internet protocols to identify the encoding used for character data, and the supported character encodings must include UTF-8. The Internet Mail Consortium (IMC) recommends that all e‑mail programs be able to display and create mail using UTF-8. UTF-8 is also increasingly being used as the default character encoding in operating systems, programming languages, APIs, and software applications. (Excerpt from Wikipedia article: UTF-8)
