An European research centre for Human Language Technologies (Q1) 3rd theme

2 04 2008

One of the most important European research centre of Human Language Technologies is Language Technology Lab (DFKI) in Germany. It is very famous because of it gets the main budget of the public.

Their mission is the improvement of language technology through novel computational techniques for processing text, speech and knowledge, a deeper understanding of human language and thought, studying the true needs of the end user and the demands of the market. Moreover, they develop novel and improved applications in three areas: Information and Knowledge Management. Document Production, Natural Communication.

These themes are elaborated in research, development and commercial projects:

  • exploiting – and automatically extending – ontologies for content processing
  • tighter integration of shallow and deep techniques in processing
  • enriching deep processing with statistical methods
  • combining language checking with structuring tools in document authoring
  • document indexing for German and English
  • automatically associating recognized information with related information and thus building up collective knowledge
  • automatically structuring and visualizing extracted information
  • processing information encoded in multiple languages, among them Chinese and Japanese


Eventually, it is important to added the last DFKI LT publications that are two:

* Thierry Declerck, Hans-Ulrich Krieger, Marcus Spies, Horacio Saggion

Human Language and Semantic Web Technologies for Business Intelligence Applications

* Hans-Ulrich Krieger, Bernd Kiefer, Thierry Declerck
A Framework for Temporal Representation and Reasoning in Business Intelligence Applications

Some Definitions for Human Language Technology (Q1) 1st theme

1 04 2008

Nowadays, The Human Language Technology is extending more and more all over the world and we can find some definitions on different pages that explain us what is.

Firstly, we have the definition that Hans Uszkoreit give us in the page of DFKI, Language technology (sometimes also referred to as human language technology) comprises 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.”

Secondly, according to wikipedia, Language technology is often called Human Language Technology (HLT) or natural language processing (NLP) and consists of computational linguistics (or CL) and speech technology as its core but includes also many application oriented aspects of them. Language technology is closely connected to computer science and general linguistics.

Lastly, to finished we can mention also the brief definition that Meraka Institute gives us:

“Human Language Technology (HLT) makes it easier for people to interact with machines. This can benefit a wide range of people – from illiterate farmers in remote villages who want to obtain relevant medical information over a cellphone, to scientists in state-of-the-art laboratories who want to focus on problem-solving with computers.”

Hans Uszkoreit (Biography) Q.1, 2nd theme

30 03 2008

As Hans Uszkoreit curriculum vitae said, he is Professor of Computational Linguistics at Saarland University. At the same time he serves as Scientific Director at the German Research Center for Artificial Intelligence (DFKI) where he heads the DFKI Language Technology Lab. By cooptation he is also Professor of the Computer Science Department.

Us<koreit 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 large machine translation project at the Linguistics Research Center. In 1984 Uszkoreit recieved his Ph.D. in linguistics from the University of Texas. From 1982 until 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 Stanford University.

Finally, his current interests are computer models of natural lagunage understanding and production, advanced applicationsof language and knowledge technologies such as semantic information systems, cognitive foundations of language and knowledge, grammar formalisms and their implementation, syntax and semantics of natural language and the grammar of German.

Here we have his Recent Publications:
