Distributed Processes for Spoken Questions and Commands Understanding
نویسندگان
چکیده
English. Commercial products labelled as smart devices usually recur to a centralised system that processes all the requests. A distributed model, where nodes independently interact with the environment, may provide a widespread support for both users and other devices. In the latter setup, each entity has a partial awareness about defines the requests accepted by the network, and this aspect complicates the task. This paper improves an existing distributed model, called PHASER, by proposing linguistic analysis techniques to manage nonmatching requests. NLP methods produce a confidence; any PHASER node forwards non-matching requests to close peers. PHASER exploits the confidence to rank the adjacent peers and deliver the question to the best node. Partial Matching and a Bag-of-Words models will be compared with the currently adopted full matching. The Bag-of-Words approach offered the best results in terms of both quality and required time. Italian. I prodotti commerciali, etichettati come dispositivi intelligenti, di solito usano un sistema centralizzato per processare le richieste. Un modello distribuito, dove i nodi interagiscono indipendentemente con l’ambiente, può fornire un supporto più ampio per gli utenti. Nel secondo setup, ogni entità è parzialmente a conoscenza delle richieste accettate da ogni nodo del network. Questo lavoro si propone di migliorare un modello distribuito esistente, chiamato PHASER, ricorrendo a tecniche di analisi linguistiche per gestire le richieste non accettate localmente; ogni nodo PHASER inoltra queste richieste ai nodi adiacenti. Metodi di NPL producono una confidence; PHASER la sfrutta per ordinare i nodi vicini e inoltrare la richiesta al migliore. Modelli basati su partial matching e bag-of-words saranno confrontati con il sistema attualmente adottato, basato su full matching. Dal confronto, bag-of-words ha riportato i risultati migliori sia di qualità che di tempo necessario per la risposta.

متن کاملStructured Learning for Context-aware Spoken Language Understanding of Robotic Commands
Service robots are expected to operate in specific environments, where the presence of humans plays a key role. A major feature of such robotics platforms is thus the ability to react to spoken commands. This requires the understanding of the user utterance with an accuracy able to trigger the robot reaction. Such correct interpretation of linguistic exchanges depends on physical, cognitive and...

Using associative memories and sparse distributed representations we have developed a system that can learn to associate words with objects, properties like colors, and actions. This system is used in a robotics context to enable a robot to respond to spoken commands like ”bot show plum” or ”bot put apple to yellow cup”. The scenario for this is a robot close to one or two tables on which there...
متن کاملSituated Spoken Dialogue with Robots Using Active Learning
In a human–robot spoken dialogue, the robot may misunderstand an ambiguous command from the user, such as ‘Place the cup down (on the table)’, thus running the risk of an accident. Although asking confirmation questions before the execution of any motion will decrease the risk of such failure, the user will find it more convenient if confirmation questions are not used in trivial situations. Th...
