Attention-Based Neural Networks for Sentiment Attitude Extraction using Distant Supervision
In the sentiment attitude extraction task, the aim is to identify
> -- sentiment relations between entities mentioned in text. In
this paper, we provide a study on attention-based context encoders in the
sentiment attitude extraction task. For this task, we adapt attentive context
encoders of two types: (1) feature-based; (2) self-based. In our study, we
utilize the corpus of Russian analytical texts RuSentRel and automatically
constructed news collection RuAttitudes for enriching the training set. We
consider the problem of attitude extraction as two-class (positive, negative)
and three-class (positive, negative, neutral) classification tasks for whole
documents. Our experiments with the RuSentRel corpus show that the three-class
classification models, which employ the RuAttitudes corpus for training, result
in 10% increase and extra 3% by F1, when model architectures include the
attention mechanism. We also provide the analysis of attention weight
distributions in dependence on the term type.Comment: 10 pages, 9 figures. The preprint of an article published in the

Using sentiment analysis technique for analyzing Thai customer satisfaction from social media
With the rapidly increasing number of Thai online customer reviews available in social media and websites, sentiment analysis technique, also called opinion mining, has become an important task in the past few years.This technique aims to analyze people’s emotions, opinion, attitudes
and sentiments.The classical approaches for opinion mining represents the reviews as bag-of-words as many words can be used to identify
positive or negative feedbacks.This makes these methods work well with European language reviews which are segmented texts.However, these
bag-of-word based methods face problem with Thai customer’s review which is non-segmented text, since Thai texts are formed as a long sequence
of characters without word boundaries.Up to now, not much research conducted on sentiment analysis for Thai customer reviews.This paper proposes
a sentiment analysis technique for Thai customer’s reviews.The proposed technique is based on the integration of Thai word extraction and sentiment
analysis techniques for mining Thai customer’s opinion. To demonstrate the proposed technique, experimental studies on analyzing Thai customer’s
reviews from social media are presented in this paper.The results show that the proposed method provides significant benefits for mining Thai
customer’s opinion from social media
The Neurocognitive Process of Digital Radicalization: A Theoretical Model and Analytical Framework
Recent studies suggest that empathy induced by narrative messages can effectively facilitate persuasion and reduce psychological reactance. Although limited, emerging research on the etiology of radical political behavior has begun to explore the role of narratives in shaping an individual’s beliefs, attitudes, and intentions that culminate in radicalization. The existing studies focus exclusively on the influence of narrative persuasion on an individual, but they overlook the necessity of empathy and that in the absence of empathy, persuasion is not salient. We argue that terrorist organizations are strategic in cultivating empathetic-persuasive messages using audiovisual materials, and disseminating their message within the digital medium. Therefore, in this paper we propose a theoretical model and analytical framework capable of helping us better understand the neurocognitive process of digital radicalization
Using social media big data for tourist demand forecasting: A new machine learning analytical approach
This study explores the possibility of using a machine learning approach to analysing social media big data for tourism demand forecasting. We demonstrate how to extract the main topics discussed on Twitter and calculate the mean sentiment score for each topic as the proxy of the general attitudes towards those topics, which are then used for predicting tourist arrivals. We choose Sydney, Australia as the case for testing the performance and validity of our proposed forecasting framework. The study reveals key topics discussed in social media that can be used to predict tourist arrivals in Sydney. The study has both theoretical implications for tourist behavioural research and practical implications for destination marketing
Sentiment Analysis of Spanish Words of Arabic Origin Related to Islam: A Social Network Analysis
With the arrival of Muslims in 711 till their expulsion in the 1600s, Arabic language was present in Spain for more than eight centuries. Although social networks have become a valuable resource for mining sentiments, there is no previous research investigating the layman’s sentiment towards Spanish words of Arabic etymology related to Islamic terminology. This study aim at analyzing Spanish words of Arabic origin related to Islam. A random sample of 4586 out of 45860 tweets was used to evaluate general sentiment towards some Spanish words of Arabic origin related to Islam. An expert-predefined Spanish lexicon of around 6800 seed adjectives was used to conduct the analysis. Results indicate a generally positive sentiment towards several Spanish words of Arabic etymology related to Islam. By implementing both a qualitative and quantitative methodology to analyze tweets’ sentiments towards Spanish words of Arabic etymology, this research adds breadth and depth to the debate over Arabic linguistic influence on Spanish vocabulary
Analysis of the Twitter discourse on sustainability using natural language processing
This publication aims to map the environmental sustainability discourse on Twitter. This will be achieved through two commonly used methods of natural language processing; topic modelling, which is used to uncover hidden themes in the document collection, and sentiment analysis, which is used to detect the attitudes of the authors of the text towards a particular attitude. The exploration of communication can provide an opportunity to find a solution to a multifaceted problem in order to protect our common future.This publication aims to map the environmental sustainability discourse on Twitter.

RuSentNE-2023: Evaluating Entity-Oriented Sentiment Analysis on Russian News Texts
The paper describes the RuSentNE-2023 evaluation devoted to targeted
sentiment analysis in Russian news texts. The task is to predict sentiment
towards a named entity in a single sentence. The dataset for RuSentNE-2023
evaluation is based on the Russian news corpus RuSentNE having rich
sentiment-related annotation. The corpus is annotated with named entities and
sentiments towards these entities, along with related effects and emotional
states. The evaluation was organized using the CodaLab competition framework.
The main evaluation measure was macro-averaged measure of positive and negative
classes. The best results achieved were of 66% Macro F-measure
(Positive+Negative classes). We also tested ChatGPT on the test set from our
evaluation and found that the zero-shot answers provided by ChatGPT reached 60%
of the F-measure, which corresponds to 4th place in the evaluation. ChatGPT
also provided detailed explanations of its conclusion. This can be considered
as quite high for zero-shot application.Comment: 12 pages, 5 tables, 3 figure
