Dialogue Games for Crosslingual Communication
We describe a novel approach to crosslingual dialogue that supports highly accurate communication of semantically complex content between people who do not speak the same language. The approach is introduced through an implemented application that covers the same ground as the chapter of a conventional phrase book for food shopping. We position the approach with respect to dialogue systems and Machine Translation-based approaches to crosslingual dialogue. The current work is offered as a first step towards the innovative use of dialogue theories for the enhancement of humanâhuman dialogue
âAppropriatenessâ in foreign language acquisition and use: some theoretical, methodological and ethical considerations
In this contribution, I focus on the concept of âappropriatenessâ in the usage, the learning and the teaching of foreign languages. Using a participant-based
emic perspective, I investigate multilingualsâ perceptions of appropriateness in their foreign languages. Referring to the existing literature, and using previously unpublished material collected through a web questionnaire (Dewaele
and Pavlenko 2001â2003), I will show that multilinguals develop their judgements of appropriateness, a crucial aspect of sociopragmatic and sociocultural competence, as part of their socialisation in a new language/culture. However, their ability to judge appropriateness accurately does not imply that they will always act âappropriatelyâ. Indeed, the presence of conflicting norms in their
other languages may contribute to conscious or unconscious divergence from the âappropriateâ norm in a particular language. Some implications for foreign language teaching will be considered
Parsing Thai Social Data: A New Challenge for Thai NLP
Dependency parsing (DP) is a task that analyzes text for syntactic structure
and relationship between words. DP is widely used to improve natural language
processing (NLP) applications in many languages such as English. Previous works
on DP are generally applicable to formally written languages. However, they do
not apply to informal languages such as the ones used in social networks.
Therefore, DP has to be researched and explored with such social network data.
In this paper, we explore and identify a DP model that is suitable for Thai
social network data. After that, we will identify the appropriate linguistic
unit as an input. The result showed that, the transition based model called,
improve Elkared dependency parser outperform the others at UAS of 81.42%.Comment: 7 Pages, 8 figures, to be published in The 14th International Joint

Multimodality and superdiversity: evidence for a research agenda
In recent years, social science research in superdiversity has questioned notions such as multiculturalism and pluralism, which hinge on and de facto reproduce ideological constructs such as separate and clearly identifiable national cultures and ethnic identities; research in language and superdiversity, in translanguaging, polylanguaging and metrolingualism have analogously questioned concepts such as multi- and bi-lingualism, which hinge on ideological constructs such as national languages, mother tongue and native speaker proficiency. Research in multimodality has questioned the centrality of language in everyday communication as well as its paradigmatic role to the understanding of communicative practices. While the multimodality of communication is generally acknowledged in work on language and superdiversity, the potential of a social semiotic multimodal approach for understanding communication in superdiversity has not been adequately explored and developed yet â and neither has the concept of superdiversity been addressed in multimodal research. The present paper wants to start to fill this gap. By discussing sign-making practices in the superdiverse context of Leeds Kirkgate Market (UK), it maps the potentials of an ethnographic social semiotics for the study of communication in superdiversity and sketches an agenda for research on multimodality and superdiversity, identifying a series of working hypotheses, research questions, areas of investigations and domains and fields of enquiry
The emotional weight of "I love you" in multilinguals' languages
The present paper considers the perceived emotional weight of the phrase I love you in multilingualsâ different languages. The sample consists of 1459 adult multilinguals speaking a total of 77 different first languages. They filled out an on-line questionnaire with open and closed questions linked to language behavior and emotions. Feedback on the open question related to perceived emotional weight of the phrase I love you in the multilingualsâ different languages was recoded in three categories: it being strongest in (1) the first language (L1), (2) the first language and a foreign language, and (3) a foreign language (LX).
A majority of speakers felt I love you was strongest in their L1. Participants offered various explanations for their perception. Statistical analyses revealed that the perception of weight of the phrase I love you was associated with self-perceived language dominance, context of acquisition of the L2, age of onset of learning the L2, degree of socialization in the L2, nature of the network of interlocutors in the L2, and self-perceived oral proficiency in the L2
Multimodal Classification of Urban Micro-Events
In this paper we seek methods to effectively detect urban micro-events. Urban
micro-events are events which occur in cities, have limited geographical
coverage and typically affect only a small group of citizens. Because of their
scale these are difficult to identify in most data sources. However, by using
citizen sensing to gather data, detecting them becomes feasible. The data
gathered by citizen sensing is often multimodal and, as a consequence, the
information required to detect urban micro-events is distributed over multiple
modalities. This makes it essential to have a classifier capable of combining
them. In this paper we explore several methods of creating such a classifier,
including early, late, hybrid fusion and representation learning using
multimodal graphs. We evaluate performance on a real world dataset obtained
from a live citizen reporting system. We show that a multimodal approach yields
higher performance than unimodal alternatives. Furthermore, we demonstrate that
our hybrid combination of early and late fusion with multimodal embeddings
performs best in classification of urban micro-events
User requirement elicitation for cross-language information retrieval
Who are the users of a cross-language retrieval system? Under what circumstances do they need to perform such multi-language searches? How will the task and the context
of use affect successful interaction with the system? Answers to these questions were explored in a user study performed as part of the design stages of Clarity, a EU
founded project on cross-language information retrieval. The findings resulted in a rethink of the planned user interface and a consequent expansion of the set of services
offered. This paper reports on the methodology and techniques used for the elicitation of user requirements as well as how these were in turn transformed into new design
solutions
Exploring Natural Language Processing and Sentence Embeddings for Sentiment Analysis of Online Restaurant Reviews
This paper explores the application of Natural Language Processing (NLP) methods in sentiment analysis of restaurant reviews available online, for a sample of restaurants in the Algarve region. The primary objective was to develop an automated method that could efficiently extract and categorize relevant sentiments relating to five key attributes of customer satisfaction, namely food quality, service, ambient, price and restaurantâs location. Using the F1 Score the proposed method was compared against human classification benchmarks. The results showed that Universal Sentence Encoding (USE) was a suitable method for implementation due to its acceptable F1 score performance, ease of accessibility and reduced cost. The use of semantic embeddings can provide valuable insights from online reviews that could benefit the restaurant management and in general the data-driven decision-making processes businesses in the gastronomic sector
Uncovering lost potential : the shortcomings of DNBs chatbot
In 2018 DNB Bank ASA (DNB) launched their chatbot, Aino, an advanced virtual banking agent. Aino handles 55% of all the incoming chat traffic for DNBs Customer Center and is continuously being trained by AI trainers to increase the percentage of messages it can respond to. The former CEO of DNB, Rune Bjerke, stated in 2017 that by 2020, 80% of all incoming chat traffic would be handled by chatbots. However, to get closer to this target, DNBs AI trainers will have to make some priorities in the development process.
The purpose of this study is to contribute to the decision-making process of which types of problems, and intents the AI trainers should prioritize to reduce DNBs costs. The data basis is conversational logs from conversations between customers of DNB and Aino, in addition to structural interviews with four DNB employees with significant knowledge of Aino. This thesis is a mixed-methods study that consists of both statistical analyses to determine group effect, structured interviews, quantitative content analysis, statistical analyses of chatlogs, as well as analysis of economical impact.I 2018 lanserte DNB Bank ASA (DNB) sin chatbot, Aino, en avansert virtuell bankagent. Aino hÄndterer 55% av all innkommende chat-trafikk for DNBs kundesenter og blir kontinuerlig opplÊrt av AI-trenere for Ä Þke prosentandelen av meldinger den kan svare pÄ. Den tidligere konsernsjefen i DNB, Rune Bjerke, uttalte i 2017 at innen 2020 ville 80% av all innkommende chat-trafikk bli hÄndtert av chatbots. For Ä komme nÊrmere dette mÄlet, vil DNBs AI-trenere imidlertid mÄtte gjÞre noen prioriteringer i utviklingsprosessen.
Hensikten med denne studien er Ă„ bidra til beslutningsprosessen for hvilke typer problemer, og intensjoner AI-trenerne bĂžr prioritere for Ă„ redusere DNBs kostnader. Datagrunnlaget er samtalelogger fra samtaler mellom kunder av DNB og Aino, i tillegg til strukturerte intervjuer med fire DNB-ansatte med betydelig kunnskap om Aino. Denne oppgaven er et kombinasjonsstudie som bestĂ„r av bĂ„de statistiske analyser for Ă„ bestemme gruppeeffekt, strukturerte intervjuer, kvantitativ innholdsanalyse, statistisk analyse av chatlogger, i tillegg til analyse av finansiell pĂ„virkning.submittedVersionM-Ă
