Student user preferences for features of next-generation OPACs: a case study of University of Sheffield international students

Purpose. The purpose of this study is to identity the features that international student users prefer for next generation OPACs. Design/ methodology/ approach. 16 international students of the University of Sheffield were interviewed in July 2008 to explore their preferences among potential features in next generation OPACs. A semi-structured interview schedule with images of mock-up screens was used. Findings. The results of the interviews were broadly consistent with previous studies. In general, students expect features in next generation OPACs should be save their time, easy to use and relevant to their search. This study found that recommender features and features that can provide better navigation of search results are desired by users. However, Web 2.0 features, such as RSS feeds and those features which involved user participation were among the most popular. Practical implications. This paper produces findings of relevance to any academic library seeking to implement a next-generation OPAC. Originality/value. There have been no previous published research studies of users’ preferences among possible features of next-generation OPACs

Hajj Pilgrims’ Perceptions of Trust and Internet Use for (Emergency) Information

This empirical study examines the patterns of internet use during Hajj, with the broader aim of providing suggestions on how organisations can improve risk communication at crowded religious venues using traditional and new media. The research team adopted a convenience sampling strategy to conduct in-person surveys of 348 Hajj pilgrims in the vicinity of the Grand Mosque in Madinah, Saudi Arabia during the October 2013 season. Of these, 150 pilgrims used the internet and their responses were analysed using simple descriptive statistics and binary regression analyses. The findings of this study suggest that Hajj pilgrims prefer accessing the internet through their smartphone devices and laptops, and both first timers and repeat pilgrims trusted websites hosted by the Saudi Arabian authorities, and their group leaders. Additionally, findings suggest that the trust in information sources and patterns of social media use differed by demographic characteristics such as age, language and economic characteristics. This underscores the need for diversifying the use of both traditional and new media communication channels to increase the diffusion and penetration of risk information for varied groups. Cross-checking of government efforts with such empirical studies helps demonstrate whether the funds expended to improve risk communication and raise hazard awareness are on point to make the pilgrims safer. The paper concludes by acknowledging that although the internet and social media are revolutionising the kinds of information available to pilgrims, they may lead to a loss in the sanctity, simplicity and equanimity of partaking in a pilgrimage, or bring harm to pilgrims through the misuse of personal data collected through social media sites. Suggestions are made to authorities and event organisers to keep a balance between traditional and modern practices of conducting a pilgrimage and designing information and communication technologies. A call for inspiring pilgrims to not only be consumers of information, but rather, providers of information by being ever vigilant is made. Presently, few pilgrimage destinations are using the power of the internet and social media for garnering pilgrims’ participation in risk communication and crisis preparedness which is a missed opportunity

Exploring the Effects of Language Skills on Multilingual Web Search.

Multilingual access is an important area of research, especially given the growth in multilingual users of online resources. A large body of research exists for Cross-Language Information Retrieval (CLIR); however, little of this work has considered the language skills of the end user, a critical factor in providing effective multilingual search functionality. In this paper we describe an experiment carried out to further understand the effects of language skills on multilingual search. Using the Google Translate service, we show that users have varied language skills that are non-trivial to assess and can impact their multilingual searching experience and search effectiveness

E-Government Information Search by English-as-a Second Language Speakers: The Effects of Language Proficiency and Document Reading Level

A rapid increase in the use of web-based technologies - and corresponding changes in government and local council policies - in recent years, means that many vital services are now provided solely online. While this has many potential benefits, it can place additional burdens on certain demographic groups, some of whom may become considerably disadvantaged or even disenfranchised. This is particularly problematic for English-as-a Second Language (ESL) speakers, who are often immigrants or refugees and thus have a greater need to access these e-government services, and who may struggle to understand and assess the relevance of complex documents. In this work we investigate the search behaviours and performance of native English speakers and two different groups of ESL speakers when completing e-government tasks, and the effect of document readability/complexity. In contrast with previous work, our results show significant differences between groups of varying language proficiency in terms of objective search performance, time on task, and self-perceived performance and confidence. We also demonstrate that document reading level moderates the effect of language proficiency on objective search performance. The findings contribute to our existing understanding of how English language proficiency affects search for e-government topics, and have important implications for the future development of e-government services to ensure more equitable access and use

Automatic semantic annotation of Web documents

Ontologies are the most important construct of the Semantic Web. From the first attempt of using simplified RDF syntax to the advanced features of the OWL languages, ontologies have arisen as the most viable technology offering solutions to integrate various Web resources into a more intelligent Web. The work presented in this thesis is a contribution to the new generation of the Web, which should be readable and interpreted not only by humans but also by machines, such as software agents. In order to allow ontologies to achieve their role of "animating" the traditional Web into this next generation Web, it is essential to find an efficient way to map all existent Web resources onto their corresponding ontology classes. In this thesis, we propose an approach for automatic semantic annotation of Web documents which is an effective way to make the Semantic Web a reality. Such an integrated Web would greatly improve the accuracy of search engines, bring a new generation of intelligent Web services, push the limits of multi-agent technologies and improve many other areas of human activity that we cannot even imagine today. Considering the size and the speed of the growing Web, it is clear that this task cannot be achieved manually. Semi-automatic and automatic annotations of Web documents using statistical text classification methods seem to be the most promising solution. This work is focused on an approach based on Naive Bayes text classification adapted to some characteristics that are particular to Web documents. A complete software solution is developed to allow testing feasibility of such an approach. Furthermore, different variations of the text classification algorithms are tested and analysed in order to identify the most optimal approach to semantically annotate Web documents. Notably, the usage of Web documents hierarchy is explored as an option to improve the accuracy of semi-automatic and automatic annotations of Web documents. The results of each tested method are presented and commented. Finally, some aspects that could possibly be improved or approached in a different way are identified for future work

En studie i finlandssvenskars internetanvändning : språkval i digitala miljöer

Syftet med denna avhandling pro gradu har varit att undersöka vad som ligger bakom finlandssvenskars språkval i digitala webbmiljöer. Samhället har sedan 1990-talet digitaliserats i rask takt och i den västerländska civilisationen har ett liv utan internet blivit allt mer främmande. Därför är det viktigt att det uppkopplade samhället även fungerar för språkliga minoriteter och därför behöver vi undersöka hur denna grupp navigerar på internet och när de använder vilka språk och varför. Urvalet består av unga finlandssvenskar från Helsingforsområdet som alla är födda mellan åren 1995–2000. Alla talar svenska som L1-språk, men de flesta talar även finska som L1-språk, vilket avspeglar den finlandssvenska populationen väl som till hög grad är tvåspråkig, speciellt i den finländska huvudstadsregionen. Informanterna kontaktades och datan samlades in under år 2017 där det totala inspelade materialet var lite över 9 timmar långt. I studien används modern mjukvara för skärminspelning samt annoteringsprogrammet Elan vilket ger en bild av hur informanterna navigerar på sex olika webbsidor och möjliggör mätning av tiden med hög precision. Den insamlade datan operationaliserades och fördes in i SPSS där de olika variablerna kunde mätas mot varandra och jämföras med den enkätundersökning som också utgjorde en del av undersökningen. Tillvägagångsättet att samla in den här typen av data för språkforskning är relativt nytt och öppnar upp för nya framtida möjligheter inom språkforskningen. Resultaten pekade på att kompetens i finska och identifikation med den finskspråkiga folkgruppen korrelerade negativt med hur lång tid informanterna uppehöll sig på webbsidor med svenskspråkigt innehåll, det vill säga att inga belägg kunde efter hypotesprövning finnas för att en finlandssvensk identitet eller kompetens i svenska skulle ha någon påverkan på hur mycket finska eller svenska informanterna använder sig av i webbmiljöer. En negativ korrelation innebär att tiden på svenskspråkiga sidor blir mindre när informanterna uppger en högre identifikation med och kompetens i det finska språket

The impact of culture on information behaviour: a case study of the outcome of the polio eradication campaign in Nigeria

Every human being applies their acquired knowledge during the interpretation and application of information, but all the humanly acquired knowledge are shaped by the social information processing model as determined by the traditions and values embedded in their culture. Therefore, the transition from information seeking to the application within a person is not completely dependent on cognition but in the current socio-cultural interpretation of that information. The cultural background of every individual often determines the interpretation and the understanding derivable from any information. Human socio-cultural values are the intervening variables during information seeking, and they can be grouped into three, namely psychological, physiological and environmental, but none acts alone during information seeking and application. Hence, culture as a factor must be considered both psychologically and environmentally to understand its impact on IB because culture comprises of both the tangible and the intangible aspects of human life. The aim of this study is to investigate the main reason for the contrasting results of the polio campaign across the north and south of Nigeria. The study adopted a mixed method approach comprising of a semi-structured interview and focus groups for the collection of data that adequately describe cultural variables to determine the aspects of culture directly impacting on IB, such as language, customs, traditions, and religious values which cannot be quantified or counted. The research approach considered IB in its totality and viewed information not only as tools designed by human to enhance communication and conceptualization of realities but also as the means which enabled the achievement of the desired goal for both the providers and the users of information. Therefore, IB was not only viewed from the context or content of the information but from the way people search, receive and utilise information to meet their respective needs. The study considered the how ; the what ; the where and the whom people consult when in need of information or for the explanation about the information received but not understood, to determine the chosen culture group s IB By considering culture from a multi-disciplinary perspective and IB evolutionarily, the study investigates the impact of cultural orientation on IB through the way the people of Nigeria relates with the polio eradication campaign. The study links all the factors of culture, such as language, tradition, and religion to the ways people relate to information, and the findings revealed that culture plays a significant role in the IB of individuals right from the point of the perceived knowledge gap to the point of information application. The language associated with the people s religious belief was also found to be of significant influence on language preference during communication of information, as well as in the process of encoding and decoding of information. Thus, culture did not only impact on IB during information seeking and application but also the language for the communication of information. Cultural orientation significantly impacted on the way people relates to the polio campaign as a consequence of their IB, and this informed their interpretations of the polio campaign and the eventual outcome of the campaign within the north and south of Nigeria

Étude sur l’influence du vocabulaire utilisé pour l’indexation des images en contexte de repérage multilingue

Depuis quelques années, Internet est devenu un média incontournable pour la diffusion de ressources multilingues. Cependant, les différences linguistiques constituent souvent un obstacle majeur aux échanges de documents scientifiques, culturels, pédagogiques et commerciaux. En plus de cette diversité linguistique, on constate le développement croissant de bases de données et de collections composées de différents types de documents textuels ou multimédias, ce qui complexifie également le processus de repérage documentaire. En général, on considère l’image comme « libre » au point de vue linguistique. Toutefois, l’indexation en vocabulaire contrôlé ou libre (non contrôlé) confère à l’image un statut linguistique au même titre que tout document textuel, ce qui peut avoir une incidence sur le repérage. Le but de notre recherche est de vérifier l’existence de différences entre les caractéristiques de deux approches d’indexation pour les images ordinaires représentant des objets de la vie quotidienne, en vocabulaire contrôlé et en vocabulaire libre, et entre les résultats obtenus au moment de leur repérage. Cette étude suppose que les deux approches d’indexation présentent des caractéristiques communes, mais également des différences pouvant influencer le repérage de l’image. Cette recherche permet de vérifier si l’une ou l’autre de ces approches d’indexation surclasse l’autre, en termes d’efficacité, d’efficience et de satisfaction du chercheur d’images, en contexte de repérage multilingue. Afin d’atteindre le but fixé par cette recherche, deux objectifs spécifiques sont définis : identifier les caractéristiques de chacune des deux approches d’indexation de l’image ordinaire représentant des objets de la vie quotidienne pouvant influencer le repérage, en contexte multilingue et exposer les différences sur le plan de l’efficacité, de l’efficience et de la satisfaction du chercheur d’images à repérer des images ordinaires représentant des objets de la vie quotidienne indexées à l’aide d’approches offrant des caractéristiques variées, en contexte multilingue. Trois modes de collecte des données sont employés : l’analyse des termes utilisés pour l’indexation des images, la simulation du repérage d’un ensemble d’images indexées selon chacune des formes d’indexation à l’étude réalisée auprès de soixante répondants, et le questionnaire administré aux participants pendant et après la simulation du repérage. Quatre mesures sont définies pour cette recherche : l’efficacité du repérage d’images, mesurée par le taux de succès du repérage calculé à l’aide du nombre d’images repérées; l’efficience temporelle, mesurée par le temps, en secondes, utilisé par image repérée; l’efficience humaine, mesurée par l’effort humain, en nombre de requêtes formulées par image repérée et la satisfaction du chercheur d’images, mesurée par son autoévaluation suite à chaque tâche de repérage effectuée. Cette recherche montre que sur le plan de l’indexation de l’image ordinaire représentant des objets de la vie quotidienne, les approches d’indexation étudiées diffèrent fondamentalement l’une de l’autre, sur le plan terminologique, perceptuel et structurel. En outre, l’analyse des caractéristiques des deux approches d’indexation révèle que si la langue d’indexation est modifiée, les caractéristiques varient peu au sein d’une même approche d’indexation. Finalement, cette recherche souligne que les deux approches d’indexation à l’étude offrent une performance de repérage des images ordinaires représentant des objets de la vie quotidienne différente sur le plan de l’efficacité, de l’efficience et de la satisfaction du chercheur d’images, selon l’approche et la langue utilisées pour l’indexation.During the last few years, the Internet has become an indispensable medium for the dissemination of multilingual resources. However, language differences are often a major obstacle to the exchange of scientific, cultural, educational and commercial documents. Besides this linguistic diversity, many databases and collections now contain documents in various formats that can also adversely affect their retrieval process. In general, images are considered to be language-independent resources. Nevertheless, the image indexing process using either a controlled or uncontrolled vocabulary gives the image a linguistic status similar to any other textual document and thus leads to the same difficulties in their retrieval. The goal of our research is to first identify the differences between the indexing approaches using a controlled and an uncontrolled vocabulary for ordinary images of everyday-life objects and to then differentiate between the results obtained at the time of image retrieval. This study supposes that the two indexing approaches show not only common characteristics, but also differences that can influence image retrieval. Thus, this research makes it possible to indicate if one of these indexing approaches surpasses the other in terms of effectiveness, efficiency, and satisfaction of the image searcher in a multilingual retrieval context. For this study, two specific objectives are defined: to identify the characteristics of each approach used for ordinary image indexing of everyday-life objects that can effect image retrieval in a multilingual context; and to explore the differences between the two indexing approaches in terms of their effectiveness, their efficiency, and the satisfaction of the image searcher when trying to retrieve ordinary images of everyday-life objects indexed according to either approach in a multilingual retrieval context. Three methods of data collection are used: an analysis of the image indexing terms, a simulation of the retrieval of a set of images indexed according to each of the two indexing approaches conducted with sixty respondents, and a questionnaire submitted to the participants during and after the retrieval simulation. Four measures are defined in this research: the effectiveness of image retrieval measured by the success rate calculated in terms of the number of retrieved images; time efficiency measured by the average time, in seconds, used to retrieve an image; human efficiency measured in terms of the human effort represented per average number of queries necessary to retrieve an image; and the satisfaction of the image searcher measured by the self-evaluation of the participant of the retrieval process after each completed task. This research shows that in terms of ordinary image indexing representing everyday-life objects, the two approaches investigated are fundamentally distinct on the terminological, perceptual, and structural perspective. Additionally, the analysis of the characteristics of the two indexing approaches reveals that if the indexing language differs, the characteristics vary little within the same indexing approach. Finally, this research underlines that the two indexing approaches of ordinary images representing everyday-life objects have a retrieval performance that is different in terms of its effectiveness, efficiency, and satisfaction of the image searcher according to the approach and the language used for indexing
