A multilingual SLU system based on semantic decoding of graphs of words

Calvo Lance, Marcos; Hurtado Oliver, Lluis Felip; García Granada, Fernando; Sanchís Arnal, Emilio (Springer Verlag (Germany), 2012-11)

In this paper, we present a statistical approach to Language Understanding that allows to avoid the effort of obtaining new semantic models when changing the language. This way, it is not necessary to acquire and label ...
A phonetic-based approach to query-by-example spoken term detection

Hurtado Oliver, Lluis Felip; Calvo Lance, Marcos; Gómez Adrian, Jon Ander; García Granada, Fernando; Sanchís Arnal, Emilio (Springer Verlag (Germany), 2013)

Query-by-Example Spoken Term Detection (QbE-STD) tasks are usually addressed by representing speech signals as a sequence of feature vectors by means of a parametrization step, and then using a pattern matching technique ...
A prosody-based vector-space model of dialog activity for information retrieval

Ward,Nigel G.; Werner, Steven D.; García-Granada, Fernando; Sanchís Arnal, Emilio (Elsevier, 2015-04)

Search in audio archives is a challenging problem. Using prosodic information to help find relevant content has been proposed as a complement to word-based retrieval, but its utility has been an open question. We propose ...
A Strategy for Multilingual Spoken Language Understanding Based on Graphs of Linguistic Units

Calvo Lance, Marcos (Universitat Politècnica de València, 2016-04-11)

A Train-on-Target Strategy for Multilingual Spoken Language Understanding

García-Granada, Fernando; Segarra Soriano, Encarnación; Millán, Carlos; Sanchís Arnal, Emilio; Hurtado Oliver, Lluis Felip (Springer Verlag (Germany), 2016-08)

[EN] There are two main strategies to adapt a Spoken Language Understanding system to deal with languages different from the original (source) language: test-on-source and train-on-target. In the train-ontarget approach, ...
ALBAYZIN Query-by-example Spoken Term Detection 2016 evaluation

Tejedor, Javier; Toledano, Doroteo T.; Lopez-Otero, Paula; Docio-Fernandez, Laura; Proença, Jorge; Perdigão, Fernando; García-Granada, Fernando; Sanchís Arnal, Emilio; Pompili, Anna; Abad, Alberto (Springer (Biomed Central Ltd.), 2018)

[EN] Query-by-example Spoken Term Detection (QbE STD) aims to retrieve data from a speech repository given an acoustic (spoken) query containing the term of interest as the input. This paper presents the systems submitted ...
An active learning approach for statistical spoken language understanding

García Granada, Fernando; Hurtado Oliver, Lluis Felip; Sanchís Arnal, Emilio; Segarra Soriano, Encarnación (Springer Verlag (Germany), 2011)

In general, large amount of segmented and labeled data is needed to estimate statistical language understanding systems. In recent years, different approaches have been proposed to reduce the segmentation and labeling ...
Applying Siamese Hierarchical Attention Neural Networks for multi-document summarization

González-Barba, José Ángel; Julien Delonca; Sanchís Arnal, Emilio; García-Granada, Fernando; Segarra Soriano, Encarnación (Sociedad Española para el Procesamiento del Lenguaje Natural, 2019-09)

[EN] In this paper, we present an approach to multi-document summarization based on Siamese Hierarchical Attention Neural Networks. The attention mechanism of Hierarchical Attention Networks, provides a score to each ...
Attention-based Approaches for Text Analytics in Social Media and Automatic Summarization

González Barba, José Ángel (Universitat Politècnica de València, 2021-09-02)

[ES] Hoy en día, la sociedad tiene acceso y posibilidad de contribuir a grandes cantidades de contenidos presentes en Internet, como redes sociales, periódicos online, foros, blogs o plataformas de contenido multimedia. ...
Attentional Extractive Summarization

[EN] In this work, a general theoretical framework for extractive summarization is proposed¿the Attentional Extractive Summarization framework. Although abstractive approaches are generally used in text summarization today, ...
Clasificación de textos basada en redes neuronales

Campos Mocholí, Mario (Universitat Politècnica de València, 2021-09-13)

[CA] Cada vegada són més les empreses que opten per utilitzar la intel·ligència artificial per a automatitzar tasques dins de les organitzacions, permetent així reassignar al personal dedicat a aquestes i aconseguint una ...
Combining multiple translation systems for spoken language understanding portability

García-Granada, Fernando; Hurtado Oliver, Lluis Felip; Segarra Soriano, Encarnación; Sanchís Arnal, Emilio; Riccardi, Giussepe (IEEE, 2012-12-05)

[EN] We are interested in the problem of learning Spoken Language Understanding (SLU) models for multiple target languages. Learning such models requires annotated corpora, and porting to different languages would require ...
Combining Several ASR Outputs in a Graph-Based SLU System

Calvo Lance, Marcos; Hurtado Oliver, Lluis Felip; García-Granada, Fernando; Sanchís Arnal, Emilio (Springer, 2015-11-09)
