Intelligent computational model of the descriptive grammar of the Spanish language

18.07.2008
Researchers from the Validation and Business Applications Group (VAI) at the Universidad Politécnica de Madrid’s School of Computing (FIUPM) have developed an intelligent computational model of the descriptive grammar of the Spanish language. This opens up new possibilities for the computational representation of languages and natural language processing applications.

Computational linguistics draws primarily on linguistic theories to build language representation models for computational applications. The linguistic theories are formal (i.e. mathematically expressible) models.

It takes from 5 to 10 years to develop a model in any particular language, whereas the coverage of the resulting model 55%. In other words, coverage is very limited and the cost is huge. This is an obstacle to languages, apart from English or more dominant languages, having useful applications.

To overcome this hurdle, the researchers Carolina Gallardo and Jesús Cardeñosa have examined the possibility of using descriptive grammars in place of linguistic theories. Even though they are not formal, descriptive grammars do represent the real language use.

Despite their not very formal “look”, descriptive grammars do contain a great deal of linguistic knowledge, these researchers explain. The real strength of these descriptive grammars is that they exist for all languages, they are low cost and they can be used in the absence of linguistic experts.

The School of Computing researchers experimented with the Royal Academy of the Spanish Language’s Descriptive Grammar of the Spanish Language (GDLE) and built a computational model that will be applicable to descriptive grammars of other languages. The innovation of this research is that knowledge elicitation methodologies proper to knowledge engineering (a branch of artificial intelligence) were applied to the GDLE, which was used as a source of knowledge.

This model has been tested on a blackboard-based application, which is one of artificial intelligence undisputed designs for somewhat complex distributed applications. It has been tested on numerous cases and the results are promising.

The model will be useful for building natural language processing applications ranging from language analysis to generation and will be applicable to any language where a natural language model with reasonable coverage needs to be developed relatively quickly.

A preview of this work was published in the proceedings of IKE’08 (2008 International Conference on Information and Knowledge Engineering), held at Las Vegas (USA) from 14th to 17th July.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
