Word of mouth muntligt och via sociala medier : - På vilket sätt påverkar det turisters reseplanering? / Word of mouth Face to face and via social media : - In what way does the tourist get effected in their travelplanning?

Hugosson, Jennie, Ahlberg, Madeleine January 2017 (has links)
Vår studie belyser hur informationsspridning både muntligt och via internet kan påverka turisters reseplaneringsprocess. Studien undersöker vilka känslomässiga attityder individer upplever genom word of mouth och electronic word of mouth och hur vida dessa attityder påverkar valet av ett nytt resmål. Syftet med studien är att undersöka hur word of mouth kan påverka turisters val av nya resmål. För att möjliggöra detta har vi genomfört intervjuer med respondenter utifrån förutbestämda kriterier: personer som reser, använder sociala medier och är mellan 20-60 år gamla. Vi lyfter fram huvudbegreppet word of mouth som det finns mycket forskning kring där även ett nytt begrepp har framkommit, electronic word of mouth då internetutvecklingen bidrog till att sociala medier har blivit en ny plattform för information. Genom dessa begrepp lyfts fenomenet fram och genom begreppen turistblicken och reseplaneringsprocessen förklaras människans beteende som turist. Vår studie visar att respondenterna blir påverkade av word of mouth och eletronic word of mouth. Resultatet av studien konstaterar att word of mouth är en informationskälla och electronic word of mouth är en inspirationskälla som båda upplevs som en viktig del i reseplaneringsprocessen. Majoriteten av respondenterna har rest till ett nytt resmål utifrån electronic word of mouth och anser att word of mouth är ett viktigt komplement i reseplaneringsprocessen.

Desambiguação lexical de sentidos para o português por meio de uma abordagem multilíngue mono e multidocumento / Word Sense Disambiguation for portuguese through multilingual mono and multi-document

Fernando Antônio Asevêdo Nóbrega 28 May 2013 (has links)
A ambiguidade lexical é considerada uma das principais barreiras para melhoria de aplicações do Processamento de Língua Natural (PLN). Neste contexto, tem-se a área de Desambiguação Lexical de Sentido (DLS), cujo objetivo é desenvolver e avaliar métodos que determinem o sentido correto de uma palavra em um determinado contexto por meio de um conjunto finito de possíveis significados. A DLS é empregada, principalmente, no intuito de prover recursos e ferramentas para diminuir problemas de ambiguidade e, consequentemente, contribuir para melhorias de resultados em outras áreas do PLN. Para o Português do Brasil, pouco se tem pesquisado nesta área, havendo alguns trabalhos bem específicos de domínio. Outro fator importante é que diversas áreas do PLN engajam-se no cenário multidocumento, onde a computação é efetuada sobre uma coleção de textos, todavia, não há relato de trabalhos de DLS direcionados a este cenário, tampouco experimentos de desambiguação neste domínio. Portanto, neste trabalho de mestrado, objetivou-se o desenvolvimento de métodos de DLS de domínio geral voltado à língua Portuguesa do Brasil e o desenvolvimento de algoritmos de desambiguação que façam uso de informações multidocumento, bem como a experimentação e avaliação destes no cenário multidocumento. Para tanto, a fim de subsidiar experimentos, desenvolvimento e avaliação deste projeto, anotou-se manualmente o córpus CSTNews, caracterizado como um córpus multidocumento, utilizando a WordNet de Princeton como repositório de sentidos, que organiza os significados por meio de conjuntos de sinônimos ( synsets) e relações linguísticas entre estes. Foram desenvolvidos quatro métodos de DLS e algumas variações, sendo: um método heurístico (para aferir valores de baseline); variações do algoritmo de Lesk (1986); adaptação do algoritmo de Mihalcea and Moldovan (1999); e uma variação do método de Lesk para o cenário multidocumento. Foram realizados três experimentos para avaliação dos métodos, cujos objetivos foram: determinar o desempenho geral dos algoritmos em todo o córpus; avaliar a qualidade de desambiguação de palavras mais ambíguas no córpus; e verificar o ganho de qualidade da desambiguação ao empregar informação multidocumento. Após estes experimentos, pôde-se observar que o método heurístico apresenta um melhor resultado geral. Contudo, é importante ressaltar que a maioria das palavras anotadas no córpus tiveram apenas um synset, que, normalmente, era o mais frequente, o que, consequentemente, apresenta um cenário mais propício ao método heurístico. Outro fato importante foi que, neste cenário, a diferença de desempenho entre o método de DLS multidocumento e o heurístico é estatisticamente irrelevante. Já para a desambiguação de palavras mais ambíguas, o método heurístico foi inferior, evidenciando que, para a desambiguação de palavras mais ambíguas, são necessários métodos mais sofisticados de DLS. Por fim, verificou-se que a utilização de informação multidocumento auxilia o processo de desambiguação. As contribuições deste trabalho podem ser agrupadas entre teóricas e técnicas. Nas teóricas, tem-se a investigação e análises da DLS no cenário multidocumento. Entre as contribuições técnicas, foram desenvolvidos métodos de DLS, um córpus anotado e uma ferramenta de anotação direcionados à língua Portuguesa do Brasil, que podem avançar as pesquisas em DLS para o idioma / The lexical ambiguity is considered one of the main barries to improving applications of Natural Language Processing (NLP). In this context, it has benn the area of Word Sense Disambiguation (WSD), whose goal is to develop and evaluate methods to determine the correct sense of a word in a give context by a nite set of possible meanings. The DLS is used mainly in order to provide resources and tools to reduce problems of ambiguity and thus contribute to improved results in other areas of NLP. In the Portuguese of Brazil, little has been researched in this area, with some work and specic domain. Another important factor is that many areas of NLP commit themselves in multidocument scenario, where the computation is performed on a collection of texts, however, there is no report of WSD work directed to this scenario, either disambiguation experiments in this eld. Therefore, this master thesis aimed to develop methods of WSD general domain facing the Portuguese language in Brazil and the development of algorithms that make use of disambiguation multidocument informations, as well as experimentation and evaluation of the multidocument scenario. Therefore, in order to support experiments, development and evaluation of this project, the corpus CSTNews with 50 document collections, was manually annotated by means of synsets of the WordNet Princeton. Four methods were developed: A heuristic method (to measure values fo baseline); variations of the Lesk (1986) algorithm; a adaptation of the Mihalcea and Moldovan (1999) algorithm; and a variation of the Lesk method for multidocument scenario. Three experiments were conducted to evaluate the methods, whose objectives were to determine the general performance algorithms across the corpus; evaluate the quality of disambiguation of most ambiguous words in the corpus, and check the gain quality of disambiguation by employing information multidocumento. After these experiments, it was observed that the heuristic method presents a better overall result. However, it is important to note that most of the words in the annotated corpus had only one synset, which usually was the most frequent, which, in turn, presents a scenario more conducive to the heuristic method. Another important fact was that in this scenario, the performance dierence between the heuristic method and multidocument algorithm was statistically irrelevant. As for the disambiguation of most ambiguous words, the heuristic method was lower, indicating that, for the disambiguation of ambiguous words, more sophisticated WSD methods are needed. Finally, it has been found that the use of multidocument information assists the disambiguation process. The contributions of this work can be divided between theoretical and technical. In theory, there is the research and analysis of WSD in multidocument scenario. Among the techniques contributions, WSD methods have been developed an annotated corpus and annotation tool targeted to the Portuguese language in Brazil that can advance research in WSD for the language

What you say? Word of mouth within social media

Rennison, Robyn 03 June 2012 (has links)
This paper extends the understanding of the word of mouth (WOM) concept and its new role within social media and thereafter analysing the impact that electronic WOM (eWOM) has on marketing campaigns. Quantitative descriptive research was employed, using the tweets that were part of the Vodacom Twitter network. This data was used to analyse the differences of activity and sentiment within the tweets. The collection of tweets were then measured against a proxy, Vodacom’s rebranding campaign. The researcher was able to identify the impact of the rebranding campaign on consumers through the changes in the responses before, during and after the campaign. The research found that the rebranding campaign resulted in higher levels of engagement between consumers and the brand. During the rebranding process, negative sentiments were lowered, however the end result of the campaign left consumers with more negativity regarding the branding. The paper advances marketing practitioners understanding of how WOM and social media play a critical role in today’s marketing. Consumers are no longer bystanders in the marketing process and are instead turning to social media as a source of information as well as a platform to communicate their opinions and attitudes.

Inferring Word-Meaning, Morpheme-Based, and Word-Based Second Language Vocabulary Teaching Methodologies

Liu, Qingli 07 November 2014 (has links)
In this study, an experiment was conducted to compare the three teaching methods: the inferring word-meaning method, the morpheme-based teaching method, and the word-based teaching method. The results showed that students taught by the inferring word-meaning method outperformed both the students taught by the morpheme-based method and the word-based method in terms of word retention. The possible reason is that the inferring word-meaning section enabled students to pay attention to and spend more time on each word. On the other hand, the disadvantage of the inferring word-meaning method is that it might not be an efficient way to teach a large amount of new vocabulary because it requires sufficient time for students to get involved with the context and the discussion of guessing words. Another drawback is that textbooks are seldom designed for the purpose of inferring word-meaning from context, which means that the teacher has to spend a substantial amount of time editing the dialogues or reading material from the textbook in order to give students more information to help them guess the meaning of each target word. For the morpheme-based teaching method and the word-based teaching method, there were no statistically significant differences observed. Students from both test groups achieved the same percentage of word retention.

Critical Incidents in Customer-Firm Relationships

January 2019 (has links)
abstract: When consumers find that something critically out of the ordinary has occurred, they direct attention to evaluate such a critical incident more closely. The results of this evaluation may put consumers on a switching path or it might lead them to engage in unfavorable behaviors from the perspective of the organization, such as engaging in negative word-or-mouth online. The negative consequences of some product (goods or services) failures go beyond simple product attribute defects, leading customers to terminate the relationship with the organization. This dissertation, which is composed of three essays, investigates how consumers engage in negative word-of-mouth on social media channels in response to their various product failures and explores an important relationship event of betrayal, which can be triggered by certain product failures. It investigates how betrayal is perceived by customers and influences a range of their behaviors across business-to-consumer and business-to-business contexts. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2019

Longitudinal Comparison of Word Associations in Shallow Word Embeddings

Geetanjali Bihani (8815607) 08 May 2020 (has links)
Word embeddings are utilized in various natural language processing tasks. Although effective in helping computers learn linguistic patterns employed in natural language, word embeddings also tend to learn unwanted word associations. This affects the performance of NLP tasks, as unwanted word associations propagate and amplify biases. Current word association evaluation methods for word embeddings do not account for changes in word embedding models and training corpora, when creating the rubric for word association evaluation. Current literature also lacks a consistent training and evaluation protocol for comparison of word associations across varying word embedding models and varying training corpora. In order to address this gap in prior literature, this research aims to evaluate different types of word associations, not limited to gender, racial or religious attributes, incorporating and evaluating the diachronic and variable nature of words over text data collected over a period of 200 years. This thesis introduces a framework to track changes in word associations between neutral words (proper nouns) and attributes (adjectives), across different word embedding models, over a temporal dimension, by evaluating clustering tendencies between neutral words (proper nouns) and attributive words (adjectives) over five different word embedding frameworks: Word2vec (CBOW), Word2vec (Skip-gram), GloVe, fastText (CBOW) and fastText (Skip-gram) and 20 decades of text data from 1810s to 2000s. <a>Finally, various cluster level and corpus level measurements will be compared across aforementioned word embedding frameworks, to find how</a> word associations evolve with changes in the embedding model and the training corpus.

To what extent do online reviews affect purchase intentions towards high involvement products? : A quantitative study exploring the differences between Generation Z and Millennial consumers.

Vu, Thi Mai Anh, Zeremichael, Simon, Wåhlberg, Sandra January 2022 (has links)
The aim of this degree project is to gain a deeper understanding of how online reviews affect consumers' purchase intentions when purchasing high-involvement products. Exploring the differences of effect between two separate generations of consumers, Generation Z and Millennials. The age intervals have been 18-41, 18-25 for Generation Z consumers and 26-41 for Millennials. This research is utilizing a deductive approach paired with a quantitative research strategy. The primary data collection method has been through an internet-based self-completed questionnaire, whereas the data later on has been analyzed. The analysis has been conducted through the Statistical Package for Social Sciences (SPSS) program allowing for the researchers to perform a series of statistical analyses. From the empirical findings and analysis conducted, it was concluded that all of the hypotheses were disproven and rejected, showing no significant difference. Through SPSS a series of independent sample t-tests were conducted to extract two means for the two generations. The statistical output displayed a higher level of impact on Millennials consumers contrary to the hypothesis, predicting Generation Z’s purchase intentions being significantly more impacted. Through SPSS the researcher have been able to compare how each generation compare against each other in terms of all the variables making up purchase intention (Involvement, Argument Quality, Source Credibility, Information Usefulness), but also performed t-tests to see how their answers differentiate in each question as well. This study could provide marketers with very insightful knowledge about how online reviews affect consumers differently, allowing for adaptation and optimizations.

Covid-19 och företagens hantering av den osäkra konsumenten : En kvalitativ studie om hur Covid-19 påverkat sambandet mellan influencer marketing, konsumtionsbeteende och osäkerhet

Vinberg, Vera, Carlsson, Isabelle January 2022 (has links)
Den exogena chocken Covid-19 har påverkat konsumtionsbeteendet vilket givit upphov till en ökad e-handel. Det har resulterat i konsekvenser vad gäller företags användning av influencer marketing och konsumenters osäkerhet vid online handel. Syftet med följande uppsats är därför att undersöka hur Covid-19 har påverkat företags sätt att använda sig av influencer marketing. Rapportens ändamål är även att undersöka hur företag inom modebranschen arbetar med strategin för att minska konsumenters osäkerhet vid köp online. En kvalitativ metod genomfördes i form av semistrukturerade intervjuer med fem respondenter från olika agenturer. Resultatet visade hur Covid-19 har utmanat företagens användning av influencer marketing till följd av det förändrade konsumtionsbeteendet som gjort att företag har uppmärksammat värdet i att finnas på de digitala kanalerna. Det framkom även att influencer marketing, genom dess trovärdiga och genuina innehåll kan reducera den upplevda osäkerheten konsumenter känner vid digitala köp.
