Specific Challenge

Recently, emotion detection in conversations becomes a hot research topic in the Natural Language Processing community. In this paper, we focus on emotion detection in multi-speaker conversations instead of traditional two-speaker conversations in existing studies. Different from non-conversation text, emotion detection in conversation text has one specific challenge in modeling the context-sensitive dependence. Besides, emotion detection in multi-speaker conversations endorses another specific challenge in modeling the speaker-sensitive dependence. To address above two challenges, we propose a conversational graph-based convolutional neural network. On the one hand, our approach represents each utterance and each speaker as a node. On the other hand, the context-sensitive dependence is represented by an undirected edge between two utterances nodes from the same conversation and the speaker-sensitive dependence is represented by an undirected edge between an utterance node and its speaker node. In this way, the entire conversational corpus can be symbolized as a large heterogeneous graph and the emotion detection task can be recast as a classification problem of the utterance nodes in the graph. The experimental results on a multi-modal and multi-speaker conversation corpus demonstrate the great effectiveness of the proposed approach.

Abstract Background Controlled vocabularies are fundamental resources for information extraction from clinical texts using natural language processing (NLP). Standard language resources available in the healthcare domain such as the UMLS metathesaurus or SNOMED CT are widely used for this purpose, but with limitations such as lexical ambiguity of clinical terms. However, most of them are unambiguous within text limited to a given clinical specialty. This is one rationale besides others to classify clinical text by the clinical specialty to which they belong. Results This paper addresses this limitation by proposing and applying a method that automatically extracts Spanish medical terms classified and weighted per sub-domain, using Spanish MEDLINE titles and abstracts as input. The hypothesis is biomedical NLP tasks benefit from collections of domain terms that are specific to clinical subdomains. We use PubMed queries that generate sub-domain specific corpora from Spanish titles and abstracts, from which token n-grams are collected and metrics of relevance, discriminatory power, and broadness per sub-domain are computed. The generated term set, called Spanish core vocabulary about clinical specialties (SCOVACLIS), was made available to the scientific community and used in a text classification problem obtaining improvements of 6 percentage points in the F-measure compared to the baseline using Multilayer Perceptron, thus demonstrating the hypothesis that a specialized term set improves NLP tasks. Conclusion The creation and validation of SCOVACLIS support the hypothesis that specific term sets reduce the level of ambiguity when compared to a specialty-independent and broad-scope vocabulary.

The success of a One Health approach to combating antimicrobial resistance (AMR) requires effective data sharing across the three One Health domains (human, animal, and environment). To investigate if there are differences in language use across the One Health domains, we examined the peer-reviewed literature using a combination of text data mining and natural language processing techniques on 20,000 open-access articles related to AMR and One Health. Evaluating AMR key term frequency from the European PubMed Collection published between 1990 and 2019 showed distinct AMR language usage within each domain and incongruent language usage across domains, with significant differences in key term usage frequencies when articles were grouped by the One Health sub-specialties (2-way ANOVA; p < 0.001). Over the 29-year period, “antibiotic resistance” and “AR” were used 18 times more than “antimicrobial resistance” and “AMR”. The discord of language use across One Health potentially weakens the effectiveness of interdisciplinary research by creating accessibility issues for researchers using search engines. This research was the first to quantify this disparate language use within One Health, which inhibits collaboration and crosstalk between domains. We suggest the following for authors publishing AMR-related research within the One Health context: (1) increase title/abstract searchability by including both antimicrobial and antibiotic resistance related search terms; (2) include “One Health” in the title/abstract; and (3) prioritize open-access publication.

Abstract Acquiring a foreign language is challenging for many adults. Yet certain individuals choose to acquire sometimes dozens of languages and often just for fun. Is there something special about the minds and brains of such polyglots? Using robust individual-level markers of language activity, measured with fMRI, we compared native language processing in polyglots versus matched controls. Polyglots (n = 17, including nine “hyper-polyglots” with proficiency in 10–55 languages) used fewer neural resources to process language: Their activations were smaller in both magnitude and extent. This difference was spatially and functionally selective: The groups were similar in their activation of two other brain networks—the multiple demand network and the default mode network. We hypothesize that the activation reduction in the language network is experientially driven, such that the acquisition and use of multiple languages makes language processing generally more efficient. However, genetic and longitudinal studies will be critical to distinguish this hypothesis from the one whereby polyglots’ brains already differ at birth or early in development. This initial characterization of polyglots’ language network opens the door to future investigations of the cognitive and neural architecture of individuals who gain mastery of multiple languages, including changes in this architecture with linguistic experiences.

Affective computing is becoming more and more important as it enables to extend the possibilities of computing technologies by incorporating emotions. In fact, the detection of users’ emotions has become one of the most important aspects regarding Affective Computing. In this paper, we present an educational software application that incorporates affective computing by detecting the users’ emotional states to adapt its behaviour to the emotions sensed. This way, we aim at increasing users’ engagement to keep them motivated for longer periods of time, thus improving their learning progress. To prove this, the application has been assessed with real users. The performance of a set of users using the proposed system has been compared with a control group that used the same system without implementing emotion detection. The outcomes of this evaluation have shown that our proposed system, incorporating affective computing, produced better results than the one used by the control group.

For propositional beliefs, there are well-established connections between belief revision, defeasible conditionals and nonmonotonic inference. In argumentative contexts, such connections have not yet been investigated. On the one hand, the exact relationship between formal argumentation and nonmonotonic inference relations is a research topic that keeps on eluding researchers despite recently intensified efforts, whereas argumentative revision has been studied in numerous works during recent years. In this paper, we show that similar relationships between belief revision, defeasible conditionals and nonmonotonic inference hold in argumentative contexts as well. We first define revision operators for abstract dialectical frameworks, and use such revision operators to define dynamic conditionals by means of the Ramsey test. We show that such conditionals can be equivalently defined using a total preorder over three-valued interpretations, and study the inferential behaviour of the resulting conditional inference relations.

Abstract This paper will explore the relationship between humans and place mediated in first-person narratives. By focusing on episodes that reveal the change in the ordinary role of the person, we examine how they describe the place and how they perceive the environment in their changed role. Drawing on interviews with a man who has walked a pilgrimage/hiking trail as well as a written life story from the collections of the Estonian Cultural History Archives, we analyse the description of modern journeys and the journeys that took place in the vortex of events during World War II. We suggest that the descriptions of place-making under consideration are related not only to subjective experiences and storytelling skills, but also to more general contexts, such as historical-political, economic, or religious frames. Comparing various kinds of place-making description we attempt to find the universal and context-sensitive aspects of journey descriptions. Finally, based on studies of oral history and cultural borders on the one hand, and pilgrimage studies on the other, a methodological question is asked: how should one apply these research methods and results to place-making research? Combining these research methods has turned out to be fruitful in creating a dialogue between experiences that have been formed in different circumstances, and through this to understand better the factors determining one’s sense of place.

This chapter uses the framework of covert exercitives to explore potential harms of actions involving certain types of pornography. The sorts of pornography of interest are clarified and the pornographic is shown to be context sensitive. This chapter focuses on the harms of subordination and silencing. Langton’s account of the subordinating force of pornography is critically assessed. An alternative model, relying on the covert exercitive, is presented and its advantages are illustrated using real world examples from the law. Various kinds of silencing are identified, the speech act of refusal is clarified, and both causal and constitutive connections between actions involving pornography, on the one hand, and the harms of subordination and silencing, on the other, are here discussed.

Object Oriented Database

Any system for natural language processing must be based on a lexicon. Once a model has been defined, there is the problem of acquiring and inserting words. This task is tedious for a human operator; on the one hand he must not forget any of the words, and on the other the acquisition of a new concept requires the input of a number of parameters. In view of these difficulties, research work has been undertaken in order to integrate pre-existing “paper” dictionaries. Nevertheless, these are not faultless, and are often incomplete when processing a very specialized technical field. We have therefore searched to mitigate these problems by automating the enrichment of an already partially integrated lexicon. We work in a technical field on which we have gathered different sorts of texts: written texts, specialist interviews, technical reports, etc. These documents are stored in an object oriented database, and form part of a wider project, called REX (“Retour d’EXpérience” in French, or “Feedback of Experience” in English). Our system, called ANA, reads the documents, analyses them, and deduces new knowledge, allowing the enrichment of the lexicon. The group of words already integrated into the lexicon form the “Bootstrap” of the discovery process of new words: it collects the instances of the different concepts thought to be interesting, in order to gather the semantic information. A special module makes it possible to avoid an explosion of the size of the database. It is responsible for forgetting certain instances and maintaining the database in such a way that the order in which the texts are introduced bears no influence.

UN Security Council Resolution 1325 and the successive thematic resolutions together with a variety of reports have shaped the Women, Peace and Security (WPS) agenda. The ensuing policies and institutional responses try to deal with a variety of issues including women’s participation in peace-making initiatives and protection from sexual violence during armed conflict and in its aftermath. As such these responses are underpinned by a reactive approach with a focus on conflict and post-conflict gender-sensitive areas of intervention. While these remain worthwhile interventions, the WPS agenda, in spite of its name, inadequately addresses gender-sensitive areas in peace situations, regardless of the existence of conflicts. Building on feminist critiques of the WPS agenda and the findings and recommendations of the 2015 UN Global study on the implementation of Resolution 1325, the article argues that the WSP agenda and its prevention limb need to elaborate and integrate more explicitly and comprehensively a human rights strategy that shifts the focus from a reactive to a proactive model, one which pursues gender equality and women’s human rights in its own right, irrespective of whether conflicts erupt or not. A human rights infused WPS preventive agenda should be premised, on the one hand, on a clear understanding and endorsement of the meaning of gender equality, on the other hand, on the creation of mechanisms and process bolstering the role of international and regional human rights regimes. In particular, robust regional human rights systems have the potential to create fora for the participation of and interaction with domestic constituencies in the region. This in turn could lead to the elaboration of context sensitive, participatory solutions, grounded in international human rights law, to existing forms of discrimination against women, which during conflicts may be exacerbated, for example, in the form of sexual enslavement and abductions as reported in recent and less recent conflicts.
