Tesaurvai can extract, annotate and organize specialized terms taken from a collection of digitalized texts. Tesaurvai complies with the ISO thesaurus building standard and was developed by the VAI in conjunction with the Spanish National Research Council’s Institute of Documentary Studies on Science and Technology (formerly CINDOC).
Euralex is Europe’s most influential lexicographical congress. The InfoLex research group, based at the Universidad Pompeu Fabra’s College of Applied Linguistics is organizing the 2008 event, which will bring together professional lexicographers, publishers, researchers, specialists and anyone with an interest in dictionaries of any kind.

Tesaurvai’s key innovation is that it combines a terminology extractor capable of ordering and selecting from 1- to 10-word terms with ISO standard-compliant thesaurus building capabilities in the same tool. The extractor identifies the terms located in digital texts that are to be transferred to the thesaurus builder. The thesaurus is a systematized list of domain-representative terms.
Tesaurvai conforms to international thesaurus building and management standards and has several implementations. First, the tool can build thesauruses from scratch, through information extraction to term creation, edition and annotation. It is easy to use to establish relationships between terms and run basic and advanced word searches. Second, the Tesaurvai tool can import and export text thesauruses to XML files. Finally, it can build alphabetical and systematized indices, which can be exchanged for printing or exportation as reports.
Available as of 2008
The tool has been developed in Java and works on a database. Tesaurvai is compatible with any database manager equipped with Java Database (JDBC) connectivity.
It was developed as part of the “Cultural heritage document search based on multilingual technical resources” (Patrilex) project, supported by the Ministry of Education with the aim of generating a methodology and tools for building multilingual lexical resources.
Tesaurvai is now undergoing massive testing. As of July 2008 it will be available to any Internet user.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
