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 formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
