The Framework for Machine Translation Evaluation in ISLE is an attempt to organize the various methods that are used to evaluate MT systems, and to relate them to the purpose and context of the systems. Therefore, FEMTI is made of two interrelated classifications or taxonomies. The first classification enables evaluators to define an intended [...]

Computational linguistics is an interdisciplinary field dealing with the statistical and/or rule-based modeling of natural language from a computational perspective. This modeling is not limited to any particular field of linguistics. Traditionally, computational linguistics was usually performed by computer scientists who had specialized in the application of computers to the processing of a natural language. [...]

Machine translation (MT), is a sub-field of computational linguistics that investigates the use of computer software to translate text or speech from one natural language to another. At its basic level, MT performs simple substitution of words in one natural language for words in another. Using corpus techniques, more complex translations may be attempted, allowing [...]

The capabilities of human language technology (HLT) have grown substantially in recent years, both in the research laboratory and in the commercial marketplace. There is now a wide range of applications for HLT systems (automatic transcription of meetings, translation between languages, automatic answering of questions, text mining and access to information through spoken human-computer dialogue).
Systems [...]

OFAI Technology Group: Language Technology (LT) forms a major research area at the Austrian Research Institute for Artificial Intelligence (OFAI) since its inception in 1984. We conduct research in modelling and processing human languages, especially for German. This includes constructing linguistic resources (such as lexicons, grammars, discourse models), processing algorithms (such as morphological components, [...]

Natural language processing (NLP) is a subfield of artificial intelligence and linguistics. It studies the problems of automated generation and understanding of natural human languages. Natural language generation systems convert information from computer databases into normal-sounding human language, and natural language understanding systems convert samples of human language into more formal representations that are easier [...]

Los ordenadores necesitan de un lenguaje específico para mostrarnos la información tal y como la vemos en pantalla, ese tipo de lenguaje se denomina lenguaje de marcado y se compone de:
Dato: “es una representación simbólica (numérica, alfabética, etc.), de un atributo (…) El dato no tiene valor semántico en sí mismo”(Wikipedia, 17/01/07) por lo que [...]

Usually it is not possible to distinguish between (raw) data and metadata because:
Something can be data and metadata at the same time. The headline of an article is both its title (metadata) and part of its text (data).
Data and metadata can change their roles. A poem, as such, would be regarded as data, but if [...]

In general, data consist of propositions that reflect reality. A large class of practically important propositions are measurements or observations of a variable. Such propositions may comprise numbers, words, or images.
In computer science, data is often distinguished from programs. A program is a set of instructions that detail a computation or task for the computer [...]
