Patent CA-2473198-A1 (CA)
Inventor: GUDBJARTSSON HAKON
IPC: G06F17/30
Filed: 2003-02-05
Abstract: Cette invention a trait à un profil d'utilisation, rencontré communément dans de nombreuses applications logicielles, relatif à la définition d'ensembles d'objets fondés sur des attributs d'objet. Elle concerne un langage de définition d'ensemble (SDL), spécialement conçu, permettant de définir des ensembles ainsi qu'un logiciel mettant ce langage en application, de manière satisfaisante, au sommet d'un système classique de gestion de base de données relationnelles (SGBDR). Les seules particularités de ce langage SDL résident dans les contraintes implicites imposées aux données relationnelles relevant des objets. Sont également uniques à ce système SDL, les métadonnées logiques dont les dimensions permettent à ce système d'imposer ces contraintes en matière de relations. Le système SDL fait intervenir plusieurs techniques d'optimisation pour permettre une mise en application satisfaisante au sommet d'un SGBDR. L'invention porte, de plus, sur des outils de composition de requêtes facilitant la création d'expressions de SDL.

Abstract: A system and method for non-speech input or keypad-aided word and spelling recognition is disclosed. The method comprises performing spelling recognition via automatic speech recognition (ASR) on received speech from a user, the ASR  being performed using a statistical letter model trained on domain data and producing a letter lattice R LN. If an ASR confidence is below a predetermined level, then the method comprises receiving non-speech input from the user, generating a keypad constraint grammar K and generating a letter string based on a composition of finite state transducers R LN and K. Other variations of the invention include recognizing input by first receiving non-speech input, dynamically generating an unweighted grammar, generating a weighted grammar using domain data, and then performing speech, and thus spelling, recognition on input speech using the weighted grammar.
