Definition of Human Language Technologies (Q.1)

There are many definitions of Human Language Technologies which can be found on the Net. The free encyclopedia Wikipedia refers to the term as Natural Language Processing (NLP) and defines:

“It is a sub-field of artificial intelligence and computational 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. Natural-language-understanding systems convert samples of human language into more formal representations that are easier for computer programs to manipulate.”

There is another definition written by Hans Uszkoreit in his study What is Language Technology? He says:

“It compromises computational methods, computer programs and electronic devices that are specialized for analyzing, producing or modifying texts and speech. These systems must be based on some knowledge of human language. Therefore language technology defines the engineering branch of computational linguistics.”

Uszkoreit studied Linguistics and Computer Science at the Technical University of Berlin and the University of Texas at Austin. During his time in Austin he also worked as a research associate in a large machine translation project at the Linguistics Research Center. In 1984 Uszkoreit received his Ph.D. in linguistics from the University of Texas. From 1982 to 1986, he worked as a computer scientist at the Artificial Intelligence Center of SRI International in Menlo Park, Ca. During this time he was also affiliated with the Center for the Study of Language and Information at Standford university as a senior researcher and later as a project leader. In 1986 he spent six months in Stuttgart on an IBM Research Fellowship at the Science Division of IBM Germany. In December 1986 he returned to Stuttgart to work for IBM Germany as a project leader in the project LILOG (Linguistics and Logical Methods for the Understanding of German Texts). During this time, he also taught at the University of Stuttgart.
