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: Goodbye, silicon? On the way to new electronic materials with metal-organic networks

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.

Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Im Focus: Disrupting crystalline order to restore superfluidity

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.

We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
