MPEG-4 Part 14 or MP4, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The only official filename extension for MPEG-4 Part 14 files is .mp4. (Excerpt from Wikipedia article: MPEG-4 Part 14)

MPEG-1 is a standard for lossy compression of video and audio. It is designed to compress VHS-quality raw digital video and CD audio down to 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) possible.

MPEG-4 is a collection of methods defining compression of audio and visual (AV) digital data. It was introduced in late 1998 and designated a standard for a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC1/SC29/WG11) under the formal standard ISO/IEC 14496 - Coding of audio-visual objects. Uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications.

MUVE (plural MUVEs) refers to online, multi-user virtual environments, sometimes called virtual worlds. While this term has been used previously to refer to a generational change in MUDs, MOOs, and MMORPGs, it is most widely used to describe MMOGs that are not necessarily game-specific. The term was first used in Chip Morningstar's 1990 paper The Lessons of Lucasfilm's Habitat. A number of the most popular and well-known MUVEs are listed below, although there are a number of others. Modern MUVEs have 3D third-person graphics, are accessed over the Internet, allow for some dozens of simultaneous users to interact, and represent a persistent virtual world.

named entity recognition

Named entity recognition (NER) (also known as entity identification and entity extraction) is a subtask of information extraction that seeks to locate and classify atomic elements in text into predefined categories such as the names of persons, organizations, locations, expressions of times, quantities, monetary values, percentages, etc. State-of-the-art NER systems for English produce near-human performance.

In general, a namespace is a container that provides context for the identifiers (names, or technical terms, or words) it holds, what allows the disambiguation of homonym identifiers residing in different namespaces. For many programming languages, a namespace is a context for their identifiers. In an operating system, an example of namespace is a directory. Each name in a directory uniquely identifies one file or subdirectory, but one file may have the same name multiple times. (Excerpt from Wikipedia article: Namespace)

native applications

A native application (native app) is an application program that has been developed for use on a particular platform or device. Because native apps are written for a specific platform, they can interact with and take advantage of operating system features and other software that is typically installed on that platform. Because a native app is built for a particular device and its operating system, it has the ability to use device-specific hardware and software, meaning that native apps can take advantage of the latest technology available on mobile devices such as a global positioning system (GPS) and camera. This can be construed as an advantage for native apps over Web apps or mobile cloud apps. (Excerpt from this source)

natural language processing

Natural language processing (NLP) is a field of computer science and linguistics concerned with the interactions between computers and human (natural) languages. In theory, natural-language processing is a very attractive method of human-computer interaction. Natural language understanding is sometimes referred to as an AI-complete problem, because natural-language recognition seems to require extensive knowledge about the outside world and the ability to manipulate it. NLP has significant overlap with the field of computational linguistics, and is often considered a sub-field of artificial intelligence. Modern NLP algorithms are grounded in machine learning, especially statistical machine learning. Research into modern statistical NLP algorithms requires an understanding of a number of disparate fields, including linguistics, computer science, and statistics. For a discussion of the types of algorithms currently used in NLP, see the article on pattern recognition. (Excerpt from Wikipedia article: Natural language processing)

network protocol

A communications protocol (also known as a network protocol) is a formal description of digital message formats and the rules for exchanging those messages in or between computing systems and in telecommunications. Protocols may include signaling, authentication and error detection and correction capabilities. A protocol describes the syntax, semantics, and synchronization of communication and may be implemented in hardware or software, or both. (Excerpt from Wikipedia article: Network protocol)

network service

A network service is a service that is provided on-line (digitally). 'Informational' network services include those that provide access to, or metadata about, items or collections at a digital location. Examples include Web sites, document supply services, abstracting and indexing services, data archives, online catalogues, databases, email archives, etc. 'Transactional' network services are those that are not primarily concerned with the supply of information, for example format conversion, printing, authentication or e-commerce services.

NoSQL (read sometimes as noseequel) is a relational database management system that is fast and portable. It is a shell-level tool. NoSQL runs under the UNIX operating system. In contrast to the NoSQL concept, which proposes distributed data stores that cannot use SQL at all, NoSQL intentionally avoids the usage of this language. NoSQL uses the operator-stream paradigm, where a number of "operators" perform a unique function on the passed data. The stream used is supplied by the UNIX input/output redirection system so that over the pipe system, the result of the calculation can be passed to other operators. As UNIX pipes run in memory, it is a very efficient way of implementation. NoSQL is written mostly in interpretive languages that makes it not the fastest RDBMS.

Open Archives Initiative Object Reuse and Exchange (OAI-ORE) defines standards for the description and exchange of aggregations of Web resources. The OAI-ORE specification implements the ORE Model which introduces the Resource Map (ReM) that makes it possible to associate an identity with aggregations of resources and make assertions about their structure and semantics. These aggregations (sometimes called compound digital objects or compound information objects) may combine distributed resources together, and with multiple media types including text, images, data, and video. The goal of OAI-ORE is to expose the rich content in aggregations to applications that support authoring, deposit, exchange, visualization, reuse, and preservation. OAI-ORE is funded by the Mellon Foundation. Version 1.0 of the specification was released on 17 October 2008. (Excerpt from Wikipedia article: OAI-ORE)

oasis saml

Security Assertion Markup Language (SAML) is an XML-based open standard for exchanging authentication and authorization data between security domains, that is, between an identity provider (a producer of assertions) and a service provider (a consumer of assertions). SAML is a product of the OASIS Security Services Technical Committee. The single most important problem that SAML is trying to solve is the Web Browser Single Sign-On (SSO) problem, a problem also addressed by the OpenID protocol. Single sign-on solutions are abundant at the intranet level (using cookies, for example) but extending these solutions beyond the intranet has been problematic and has led to the proliferation of non-interoperable proprietary technologies.
