El objetivo es dar cuenta de los posicionamientos expresados por lo...
In this paper we present a novel resource-inexpensive architecture for metaphor detection based on a residual bidirectional long short-term memory and conditional random fields. Current approaches on this task rely on deep neural networks to identify metaphorical words, using additional linguistic features or word embeddings. We evaluate our propos...
In this paper we propose a neural network approach to detect the metaphoricity of Adjective-Noun pairs using pre-trained word embeddings and word similarity using dot product. We found that metaphorical word pairs tend to have a lower dot product score while literal pairs a higher score. On this basis, we compared seven optimizers and two activatio...
We describe a new methodology for conceptual metaphor detection and formulation in corpora, developed within the framework of the MOMENT project for analysing mental health metaphors. We critically review state-of-the-art methods for metaphor identification in texts, highlighting their main drawbacks for metaphor analysis in large corpora, mainly p...

La noción de similitud es crucial para un número de disciplinas del ámbito cognitivo y lingüístico. Sin embargo, se trata de un concepto amplio que se puede tratar desde diversas perspectivas de estudio. En el presente trabajo realizamos un análisis comparativo de cómo dos de estas perspectivas articulan la similitud entre los sentidos verbales en...
Similarity, which plays a key role in fields like cognitive science, psycholinguistics and natural language processing, is a broad and multifaceted concept. In this work we analyse how two approaches that belong to different perspectives, the corpus view and the psycholinguistic view, articulate similarity between verb senses in Spanish. Specifical...

In this framework, a corpus of first-person accounts from both grou...
Word recognition includes the activation of a range of syntactic and semantic knowledge that is relevant to language interpretation and reference. Here we explored whether or not the number of arguments a verb takes impinges negatively on verb processing time. In this study, three experiments compared the dynamics of spoken word recognition for ver...

Spelling and grammar checking has become a daily activity for almost all text processor users. Usually these tools offer limited information about the misspelling or the grammar error and in certain cases suggest one or more possible alternatives. Sometimes users make the same mistakes one day after the other because they don't know the real reason...

The MOMENT project aims to contribute to a better understanding of severe mental disorders (schizophrenia, bipolar disorder, severe depression and obsessive-compulsive disorder) by analysing the discourse of the two main groups involved: people with a mental health diagnosis and mental health professionals. This analysis uses the Conceptual Metaphor Theory. The two main objectives are: 1) to detect and systematize dominant conceptualizations of the disorders, and 2) to promote changes in discourse in order to improve public health communication and communications between patients and professionals.
SPECIFIC GOALS:
1. To build a hand-annotated corpus of first-person testimonies published online (in blogs, on Twitter, etc.) by patients and professionals in Spain. This corpus will be used both for discourse analysis and as a testing ground for automatic metaphor detection.
2. To analyse first-person accounts from people diagnosed with a severe mental disorder and from mental health professionals in order to detect: 1) what kind of metaphors are used by these two groups when talking about the mental disorder and related experiences, and what similarities and differences there are between groups on two levels, intergroup (patients vs. professionals) and intragroup (type of severe mental disorder and professional profile); and 2) what kind of discourses are built upon the uses of these metaphors: biomedical discourses, which tend to disempower affected people, or alternative humanistic discourses, which tend to promote patients’ agency.
3. To improve the methodology for detecting metaphors and codifying them in corpora, with the aim of contributing to solving the methodological problems common to any application of the Conceptual Metaphor Theory.
4. To improve the methodology for automatic metaphor detection, thus contributing to a cutting-edge area of research in the field of computational linguistics.
5. To contribute to the debate on how we should talk about mental disorders. A compendium of metaphors is going to be created based on the results obtained; this is to promote: 1) public communications about mental health that are more useful and respectful, and 2) better awareness of patients’ narratives among professionals.
MULTIDISCIPLINARY RESEARCH TEAM
The multidisciplinary team conducting this project shares extensive experience in applied linguistics and in several fields relating to mental health (psychology, social education and medical anthropology). As such, MOMENT is a collaborative project aiming to mobilize knowledge combined from various scientific fields to face one of the great challenges of our society: to improve our understanding of severe mental disorders.
