Sentiment analysis has become a phenomenon with the proliferation of social media and the popularity of opinion-rich resources such as online reviews and blogs. Even though significant advances have been achieved in this field, there are still some major challenges to be addressed – i.e. sentiment analysis in multiple languages or thematic domains. Only a few studies have focused on minor or morphologically rich languages. Moreover, it is a question of whether the results of sentiment analysis could be further improved by incorporating the surrounding context (local or chronological) of the analyzed document. This paper presents a language- and domain-independent sentiment analysis model based on character n-grams which improves the classifiers performance by utilizing surrounding context.
Four experiments on various datasets were conducted in order to validate the model. The datasets included a reference corpus containing movie reviews in English, movie reviews in the Czech language, the bestselling Amazon book of 2012 Fifty Shades of Grey novel reviews dataset from three Amazon language mutations (English, German, and French), another reference corpus containing Amazon reviews in multiple languages (German, French, and Japanese), and a multi-domain dataset (movies, books, and product categories ranging from electronics and home appliances to sports gear and supplies for hobbies and pets).
The experiments confirmed the approach of incorporating the surrounding context in order to be effective for datasets from various languages and domains, suggesting a strong performance of a character n-gram based model for multi-domain and language datasets as well. A simple all-in-one classifier, which uses a mixture of labeled data from multiple languages (or domains) to train a sentiment classification model, may rival more sophisticated domain/language adaptation techniques. Such an approach reflects the needs of companies – with the interconnectedness of today’s world, most companies operate across multiple markets and would find it difficult to obtain a specific sentiment analysis solution for each market they serve.
Odezvu spotřebitele na reklamu ovlivňuje celá řada aspektů. Mezi nejvýznamnější se řadí užité barvy a emocionální apely. Využití barev a emocionálních apelů se přitom může lišit v závislosti na tom, do kterého odvětví či produktové skupiny nabízený produkt/ služba patří. Stejně tak lze k podpoře různých emocionálních apelů využít odlišných barevných schémat. V rámci tohoto výzkumu
je analyzován výzkumný vzorek reklamních spotů vysílaných v České republice v roce 2016. Výzkumný vzorek zahrnuje 200 reklamních spotů na základě náhodného stratifikovaného výběru, kde stratami jsou v tomto smyslu produktové kategorie NACE, které reprezentují 90 % všech odvysílaných reklam. Hlavním cílem tohoto výzkumu je analyzovat využití emocionálních apelů v televizní reklamě, dílčím cílem je dále prozkoumat závislost využití barev pro vyjádření různých emocionálních apelů. Výsledky indikují, že existují statisticky významné rozdíly ve využití emocionálních
apelů v reklamách inzerujících produkty náležející do různých produktových kategorií. U kategorie potravin a nápojů jsou častěji využity apely jako humor a vřelost, více než v jiných produktových kategoriích jsou ale také zastoupeny informativní reklamní spoty, které emocionálních apelů nevyužívají vůbec. U kategorie dalšího zpracovatelského průmyslu jsou významně více využívány apely jako humor a strach, naopak mnohem méně je využíváno apelu erotiky. Peněžnictví a pojišťovnictví často užívá v reklamních spotech humoru, překvapivě v oblasti kultury jsou významně zastoupeny reklamy, které sází na jiné techniky než využití emocionálních apelů. Statisticky významné rozdíly byly nalezeny i ve využití barev k vyjádření různých emocionálních apelů. Barvami
erotiky jsou černá a červená, strach bývá vyjádřen za přítomnosti rovněž červené, ale také bílé a zelené barvy. Pro vyjádření humoru se používá překvapivě šedivá barva, dále pak červená, fialová či
bílá. Vřelost bývá vyjadřována zemitou hnědou, ale také růžovou, či překvapivě šedivou.
The study analyses mass media communication by mortgage lenders in the Czech market and builds on Kotler’s competitive strategies concept and aims to answer the question of whether there is a relationship between the mortgage lenders’ market position and their mass media communication profile. Furthermore, it analyses the mass media communication of mortgage lenders according to their financial performance. The analysis utilizes complete monitoring data from the mass media market in the Czech Republic. As a result of this study, the different advertising patterns of the market leaders and challengers on a highly commoditised market are shown. Market leaders do not utilise defensive strategies to protect their market shares but employ more offensive strategies to increase the size of the market. Market challengers have no resources to implement a massive and offensive communication strategy to challenge the market leaders.
Such a conclusion contributes to the debate on communication strategies for distinct types of companies according to their position on the market and their market share.
The purpose of this research is to analyze the scheduling factors and their influence on TV advertising effectiveness. We deployed a quantitative approach based on a complete data set of advertisements aired on Czech TV in 2016 and 2017 for constructing a regression model. In contrast to several previous studies, our findings indicate that most analyzed variables have only a negligible influence (length of the spot, length of the break, number of spots, position in the break, category, a day of the week, week, year, and interaction of week and year) on TV advertising exposure, while only the type of programme, daypart and TV channel show a relevant impact on advertising exposure.
The article aims to determine the extent of gender-related differences in user satisfaction with websites with a focus on the asymmetric and nonlinear effects of customer satisfaction. An experiment was conducted with 15 men and 15 women who undertook a typical task (scenario) on 44 websites. Overall, 1,320 evaluations of website quality attributes were obtained and analyzed. The results reveal that men and women differ in their website quality assessment. Marketing professionals should consider their target audience’s gender when designing a quality website, or even devise ways of approaching both gender groups through distinct means.
The aim of this study is to analyze the differences in color schemes in TV commercials across different product categories. The study answers the question of whether advertisers in different industries use specific color schemes to promote their company or products in TV commercials and if they follow the general recommendations for using colors in marketing communications. The research sample consists of 200 video adverts proportionally representing the commercials aired in six major product categories in the Czech Republic in 2016. The results indicate there is no statistically significant difference in the usage of colors between the product categories. Nevertheless, the advertisers in the Czech Republic generally follow the color scheme recommendations suggested by the theory.
Článek analyzuje vliv proliferace médií na vývoj reklamního trhu v masmédiích v ČR v letech 2010–2016. Pro naplnění cílů je využito dat z kompletního monitoringu českého reklamního prostoru a deskriptivní analýza pracuje s ukazateli: celkový počet mediálních kanálů v rámci mediatypu, celkový počet a celkový objem reklamních sdělení v rámci mediatypu, celkový počet a celkový objem reklamních sdělení v rámci mediatypu, suma investic do reklamního prostoru v rámci mediatypu, průměrné investice na jednom kanálu, průměrná cena za jedno reklamní sdělení a průměrná cena za sekundu reklamního prostoru (pro TV a rozhlas).
Výsledky ukazují, že jednotlivá masmédia reagují na proliferaci odlišně. U televize krátkodobě došlo k propadu a rozmělnění poptávky mezi narůstající počet nových kanálů. V delším období ale počet reklam rostl více než dvojnásobně v porovnání s celkovým dostupným reklamním prostorem, za současného snižování ceny reklamního prostoru. U rádia se prostor nabízený českými stanicemi příliš nezměnil, přesto objem reklam vzrostl o čtvrtinu. Cena reklamního prostoru kolísala, suma investic do reklamy však vykazovala stabilní rostoucí trend. V oblasti tisku i přes masivní nárůst počtu titulů došlo k propadu poptávky po reklamním prostoru. Vydavatelé se propad snažili kompenzovat zejména nárůstem ceny reklamního prostoru. Proliferace masmediálního trhu byla pozitivním jevem zejména pro inzerenty a projevila se zejména vyšší přístupností reklamního trhu. Rovněž vedla k narovnání trhu a ke zmenšení rozdílů mezi jednotlivými poskytovateli reklamního prostoru.
The purpose of the article is to explore one of the Cental and East European media markets to determine whether different audience profiles reflect the various industry structures of the commercials aired. The article is based on data from a complete television (TV) commercials data set (n=2,303,435) from 2013. The results indicate that there are only minor differences between TV channels while audience targeting is only implemented by a very few thematic channels. The article contributes to media marketing management research by showing that the differences in the distribution of commercials among different TV channels are smaller than expected.
Sentiment analysis and opinion mining seems to be a hot topic these days. Together with the spontaneous and massive expansion of new media (esp. social networks) this issue is being perceived as one of the major trends for the nearest future. Google Trends (a tool showing how often a particular search-term has been entered across various regions of the world and in various languages) reports a fivefold increase of search queries since 2007. However opinion mining and sentiment analysis are not only a recent phenomenon related to the development of information technology. A long time before the World Wide Web was born, our attitudes or (consumer’s) decisions had been influenced by our relatives or friends around us. As we specialize and narrow our focus, the more frequently we need additional information about certain fields. Thus we have been looking for specialists or professionals with (life) experience who are able to share their opinion or advice. A car enthusiast whom we know could recommend a mechanic or a garage, a respectable person we appreciate could help us with the decision for whom to vote in the local election, or a colleague might provide a reference about a job applicant we would like to hire for our company.
Before the mass media has evolved, people were able to receive an input from just limited surrounding. This neighborhood was more likely limited to the geographical area where the individual lived and to the community they belonged to. As the TV and radio became widespread, the range of people who could influence public meaning greatly expanded. The distance is no longer a barrier and audiences can be approached in many ways. Persons speaking to the audience through the broadcast became strong opinion makers influencing and changing public attitudes and beliefs. Besides the crème de la crème of world politics (i.e. Barack Obama, Mario Monti, Mitt Romney or Hillary Clinton) and CEOs of the largest companies (i.e. Tim Cook from Apple, Sheryl Sandberg from Facebook or Virginia Rometty from IBM) the Time Magazine’s List of The World’s 100 Most Influential People from 2012 also includes sport players (Jeremy Lin, Novak Djokovic, or Lionel Messi) artists (Rihanna, Adele) or even famous Chefs (Jose Andres). Many of those ”celebrities” do influence masses in the areas far beyond their expertise.
The online environment made it further possible to find out what others are thinking or experiencing, no matter if those are our personal contacts or well know professionals. In 2008, Pew Internet & American Life Project Report discovered that more than 80 percent of US internet users have previously done dome online research about a product. Twenty percent do so commonly. More than 75 % of online-hooked customers confirm that reviews have a significant influence on their purchase and they are willing to pay more for a product with better customer reviews. In addition, one third of users has posted an online review or rating regarding a product or service and thus became an influencer themselves.
Therefore continuous and systematic new media monitoring became an integral part of company processes. The aim of such activities is to recognize whether and (if so) in which context the media speaks about the company, hence companies can adjust their strategies and react in advance according to public opinions or attitudes. George Washington, the first President of the US, at the end of 18th century, monitored newspapers to monitor attitudes of his fellow citizens and what they were saying about him. Many of his successors also analyzed their media picture and 19th century witnessed an explosion of new companies scanning the media and cutting out news, providing the reports to government institutions, companies or individuals.
First press cutting (called “clipping” in the US) services retrieved information from media manually. They employed human readers to scan newspapers and look for keywords of (multiple) clients. Even if such services served only to a limited geographic area (mostly just one country) and monitored the media in just one single language, the human readers typically missed one third of articles containing keywords (as a result of not reading thoroughly but only fast scanning the articles). In the 1950s companies started to monitor TV broadcasts. Again, contracted personnel watched all programs and monitored broadcasted contents for keywords. With the introduction of Betamax and VHS technology, the monitoring process enabled recording and post-processing. Moreover, first automated speech-to-text systems have been developed, although they were still only 70–80 % complete and accurate.
The introduction of World Wide Web in 1990s brought revolutionary changes on the media market. Almost all media are now digitalized and available online. New monitoring companies offer a computer-based processing where country borders or national languages do not matter anymore. CyberAlert – the world press clipping service – monitors 55 000+ online news sources in 250+ national languages 24 hours a day. New websites spontaneously emerge, change and disappear every day. A common user is not only a web content consumer, but also contributes as an author. We write product reviews, post comments in discussion forums or on social networks or even have our personal online blogs. Such fragmented and unofficial information is a significant source of word-of-mouth or “buzz” about companies and products. Many of today’s most influential blogs (i.e. The Huffington Post, Techcrunch, Engadget, Mashable) began just few years ago as one-man-show, quickly growing into internationally recognized and respected media.
Media monitoring has rapidly changed. Recognizing sentiment and finding out about people’s attitudes still remains a challenge. However, utilizing sentiment analysis, companies can gain advantage from the insight in (social) media, recognize company or product reputation or develop a new marketing strategy addressing the negative sentiment and positively impacting on consumer’s perception. Moreover, top influencers and opinion makers can be identified. Sentiment analysis may be also useful in other domains for predicting the result of (presidential) election or pointing a virtual finger at the next American Idol.
Old-fashioned press cutting services just monitored the media and did not supply any interpretation of the outputs provided. Even these days when the data are collected automatically, companies mostly interpret them manually. Such a random approach is then susceptible to subjective error and is dependent on the experience and skills of the persons performing the analysis. Nevertheless, computer-based processing and modeling allows for automated sentiment analysis. Automated systems are repeatedly able to determine the sentiment (whether positive or negative) with 70–80 % accuracy. If automated systems were absolutely correct about sentiment classification, humans would still disagree with the results about 20 % of the time which is in no contrast to the level of agreement between raters they reached in human-rated analyses.
Automated sentiment analysis became an integral part of market research activities in companies such as Kia Motors, Best Buy, Deutsche Bank, Southwest Airlines or Paramount Pictures. Although the analysis cannot provide a hundred percent certainty, it can definitely offer important insights. It could be used to gain understanding of customer experience, recognize competitive dangers or discover emerging market opportunities. Opinions floating around the cyberspace begin to represent vox populi to the degree, in which most market segments participate in online discussions. Automated sentiment analysis might be a good way how to deal with cluttered online environment and how to get insight into the mind of a new millennial consumer.
The impact of culture on consumer behaviour has been an important research area for decades. The rise of e-commerce prompted the importance of culturally bound differences between websites. Web designers are compelled to adjust website development to the cultural characteristics of the target audience and to reflect local perspectives. The actual target users are often invited to provide valuable feedback on e-commerce applications. However, user tests are extremely costly and time consuming. Tools for automated web design assessment have only recently been introduced and have provoked debate regarding their ability to simulate human interaction. In this article, 40 leading beer-brand-related websites from four different groups (countries) are analysed. The aim of this study is to discover if automated tools predicting user eye activity are able to distinguish between websites from different cultures. The findings indicate that automated tools provide quick and inexpensive results for initial assessment of the website interface, clearly differentiating between websites from different cultural backgrounds, resonating with the current literature.
Social media is an environment which supports and encourages users to express attitudes and opinions. However such fragmented and disorganized source is difficult to monitor, analyze and interpret. Automated sentiment analysis might be the next step of the marketing research providing a valuable insight in the consumers mind.
Higher education is a dynamic global industry with highly competitive and developed market. Universities communicate their international programs to attract prospective students interested in studying abroad. This study addresses a question, whether there is a difference between communicated characteristics of international programs among universities from various cultures. Websites of seventy universities coming from different cultural clusters are analysed through data-mining methods. The results suggests that marketing communications in international higher education do not stand on cultural grounds as there are only minor differences between international program communications across the world. The only difference in the group of prime international higher education providers was found between the Anglo-Saxon universities and the rest of the world.
Tourism development has an irreplaceable role in regional policy of almost all countries. This is due to its undeniable benefits for the local population with regards to the economic, social and environmental sphere. Tourist destinations compete for visitors at tourism market and subsequently get into a relatively sharp competitive struggle. The main goal of regional governments and destination management institutions is to succeed in this struggle by increasing the competitiveness of their destination. The quality of strategic planning and final strategies is a key factor of competitiveness. Even though the tourism sector is not the typical field where the benchmarking methods are widely used, such approaches could be successfully applied. The paper focuses on key phases of the benchmarking process which lies in the search for suitable referencing partners. The partners are consequently selected to meet general requirements to ensure the quality if strategies. Following from this, some specific characteristics are developed according to the SMART approach. The paper tests this procedure with an expert evaluation of eight selected regional tourism strategies of regions in the Czech Republic, Slovakia and Great Britain. In this way it validates the selected criteria in the frame of the international environment. Hence, it makes it possible to find strengths and weaknesses of selected strategies and at the same time facilitates the discovery of suitable benchmarking partners.
Website quality measurement tools have been largely static and have struggled to determine relevant attributes of user satisfaction. This study compares and contrasts attributes of user satisfaction based on usability guidelines seeking to identify practical easy-to-administer measurement tools. The website users assessed business school homepages according to six criteria and fulfilled a randomly assigned yet typical task. After completing the task, respondents assessed the same six website quality/satisfaction criteria again. The consumer–product relationship seems similar to the link between a user and a website. User satisfaction, just like consumer satisfaction, is asymmetric and non-linear. Content and navigation have been identified as key ingredients when users judged website quality, alerting web designers and website practitioners to focus more closely on those attributes. Similar lessons can be drawn for marketing professionals, who typically supervise or determine the content, structure and other website facets.
Tourism development planning is now part of the regional policies of all Member States of the European Union. Strategic plans at national or regional level are specific instruments of regional management, which contain results of the planning process and ensure the development of tourism in the selected region. The paper analyzes the representatives of these plans from Great Britain, Germany, the Czech Republic, Slovakia, Romania and Bulgaria. It evaluates their contents and form of processing according to suggested united methodology respecting main principles of current quality management. The paper tests the process of evaluation on a selected sample, compares different approaches to planning and identifies the best transferable practices as the first step of creating the complex system for evaluation and quality improvement of regional planning in tourism.
The systematic tourism promotion can be understood as a specific instrument of regional policy of Czech regions. At the present time almost all regions are disposing with the particular programme document focused on tourism development in a given region. Nevertheless, these documents are considerably different in the case of their form and content, which complicates the process of their evaluation and comparison. In order to review the documents it is necessary to set objectively the generally valid requirements on the quality of elaboration and derive from them the measurable quality marks. This is the content of the first stage of the research. Its main aim is to draft the complex procedure for evaluation of the overall quality of the tourism development programmes.
This paper summarizes the results of the second phase of the research. Its aim was to draft a procedure for evaluating the quality of tourism development programmes. The concrete requirements and quality marks were determined in the first phase of the research. So-called key characteristics were defined in order to assess the level of fulfilment of these requirements which should correspond with the quality marks. An interval method of assessment is used to evaluate the extent of matching the key characteristics in several quality levels. The evaluation process continues with the method entitled Distributively-delegative Awarding Points. Its result is the final value of the quality marks, characterizing the quality of the content and the format of the document. The chosen
procedure was applied to eight regional documents with the aim to determine the current state and the most common differences in the achievement of the quality marks.
Competences are important prerequisites for any kind of job. Competences accumulate across a long period of time. Key competences for lifelong education have been suggested even by the European Parliament and EU Council in December 2006. This article provides analysis of a nation-wide survey of desired competences at the time of global economic uncertainty. As such it may assist educators in designing suitable courses and curricula that provide graduates with competitive edge on the labor market. Key words:
Snaha pochopit motivaci spotřebitelů k nákupu a jejich myšlenkové pochody je významnou oblastí zkoumání. Na základě empirického šetření mezi téměř 117,000 majiteli osobních vozů v pěti největších evropských automobilových trzích jsou v tomto příspěvku testovány vzájemné vazby mezi spokojeností s nákupem, spokojeností s užitím a zákaznickou loajalitou. Ukazuje se, že usilovat o nového zákazníka či extrémně pečovat o dealerskou síť nemusí být nejlepší kroky automobilových firem při realizaci jejich marketingových strategií.
