[ MultiModal Systems ]

Multimodal Systems researches methods and tools to build interactive systems using information processing techniques. The research topics are defined in a context where multiple devices are used for interaction and an increasing amount of multimedia information is produced everyday. The potential of multimedia information can only be harnessed if the semantic content is properly represented. Additionally, the interface between the information space and the humans has to be carefully designed.

* Juan Otero Pombo, Universidade de Vigo (Spain)
   [ 1 Mar 2006 to 1 Jun 2006 ]
   Hosted by: Vitor Rocio

The work developed in this visit focused on the extraction of agreement information from partial parses and its use for spelling correction purposes.


* Juan Otero Pombo, Universidade de Vigo (Spain)
   [ 16 Sep 2005 to 16 Dec 2005 ]
   Hosted by: Vitor Rocio

The main target of his work was the integration of spelling correction and parsing tasks to improve the performance of both. Finding a good correction for a misspelled word is one of the currend challenges of the spelling correction tools but it is quite difficult without taking into acount some contextual infomation. Moreover, robust incomplete parsing performs better when mispelling erros are corrected. Juan Otero research has been centered arround the following topics: * Exporation of DyAlog tool, which alows the development of parsers in natural language processing. * Study of Defined Clauses Gramars (DCG's) used to implement the portuguese grammar used by my parser and its possible adaptation to spanish or galician. * Adaptation of regional spelling corrector to correct misspelled words before the parser was run. For each possible candidate to be a correction of a misspelled word, the spelling corrector obtains a prolog fact which can be processed by the parser.
