An Investigation on Text-Based Cross-Language Picture Retrieval Effectiveness through the Analysis of User Queries

Purpose: This paper describes a study of the queries generated from a user experiment for cross-language information retrieval (CLIR) from a historic image archive. Italian speaking users generated 618 queries for a set of known-item search tasks. The queries generated by user’s interaction with the system have been analysed and the results used to suggest recommendations for the future development of cross-language retrieval systems for digital image libraries. Methodology: A controlled lab-based user study was carried out using a prototype Italian-English image retrieval system. Participants were asked to carry out searches for 16 images provided to them, a known-item search task. User’s interactions with the system were recorded and queries were analysed manually quantitatively and qualitatively. Findings: Results highlight the diversity in requests for similar visual content and the weaknesses of Machine Translation for query translation. Through the manual translation of queries we show the benefits of using high-quality translation resources. The results show the individual characteristics of user’s whilst performing known-item searches and the overlap obtained between query terms and structured image captions, highlighting the use of user’s search terms for objects within the foreground of an image. Limitations and Implications: This research looks in-depth into one case of interaction and one image repository. Despite this limitation, the discussed results are likely to be valid across other languages and image repository. Value: The growing quantity of digital visual material in digital libraries offers the potential to apply techniques from CLIR to provide cross-language information access services. However, to develop effective systems requires studying user’s search behaviours, particularly in digital image libraries. The value of this paper is in the provision of empirical evidence to support recommendations for effective cross-language image retrieval system design.</p

Multilingual Information Access: Practices and Perceptions of Bi/multilingual Academic Users

The research reported in this dissertation explored linguistic determinants in online information searching, and examined to what extent bi/multilingual academic users utilize Multilingual Information Access (MLIA) tools and what impact these have on their information searching behavior. The aim of the study was three-pronged: to provide tangible data that can support recommendations for the effective user-centered design of Multilingual Information Retrieval (MLIR) systems; to provide a user-centered evaluation of existing MLIA tools, and to offer the basis of a framework for Library & Information Science (LIS) professionals in teaching information literacy and library skills for bi/multilingual academic users. In the first phase of the study, 250 bi/multilingual students participated in a web survey that investigated their language choices while searching for information on the internet and electronic databases. 31 of these participants took part in the second phase which involved a controlled lab-based user experiment and post experiment questionnaire that investigated their use of MLIA tools on Google and WorldCat and their opinions of these tools. In the third phase, 19 students participated in focus groups discussions and 6 librarians were interviewed to find out their perspectives on multilingual information literacy. Results showed that though machine translation has alleviated some of the linguistic related challenges in online information searching, language barriers do still exist for some users especially at the query formulation stage. Captures from the experiment revealed great diversity in the way MLIA tools were utilized while the focus group discussions and interviews revealed a general lack of awareness by both librarians and students of the tools that could help enhance and promote multilingual information literacy. The study highlights the roles of both IR system designers as well as LIS professionals in enhancing and promoting multilingual information access and literacy: User- centered design, user-modeling were found to be key aspects in the development of more effective multilingual information retrieval (MLIR) systems. The study also highlights the distinction between being multilingually information literate and being multilingual information literate. Suitable models for instruction for bi/multilingual academic users point towards Specialized Information Literacy Instruction (SILI) and Personalized Information Literacy Instruction (PILI)

A Review of the "Digital Turn" in the New Literacy Studies

Digital communication has transformed literacy practices and assumed great importance in the functioning of workplace, recreational, and community contexts. This article reviews a decade of empirical work of the New Literacy Studies, identifying the shift toward research of digital literacy applications. The article engages with the central theoretical, methodological, and pragmatic challenges in the tradition of New Literacy Studies, while highlighting the distinctive trends in the digital strand. It identifies common patterns across new literacy practices through cross-comparisons of ethnographic research in digital media environments. It examines ways in which this research is taking into account power and pedagogy in normative contexts of literacy learning using the new media. Recommendations are given to strengthen the links between New Literacy Studies research and literacy curriculum, assessment, and accountability in the 21st century

Multilingual Metadata for Cultural Heritage Materials: The Case of the Tse-Tsung Chow Collection of Chinese Scrolls and Fan Paintings

Purpose – The purpose of this paper is to explore multilingual access in digital libraries and to present a case study of creating bilingual metadata records for the Tse-Tsung Chow Collection of Chinese Scrolls and Fan Paintings. The project, undertaken at the University of Wisconsin-Milwaukee Libraries, provides access to digital copies of calligraphic and painted Chinese scrolls and fans from the collection donated by Prof Tse-Tsung Chow (Cezong Zhou). Design/methodology/approach – This paper examines the current approaches to multilingual indexing and retrieval in digital collections and presents a model of creating bilingual parallel records that combines translation with controlled vocabulary mapping. Findings – Creating multilingual metadata records for cultural heritage materials is in an early phase of development. Bilingual metadata created through human translation and controlled vocabulary mapping represents one of the approaches to multilingual access in digital libraries. Multilingual indexing of collections of international origin addresses the linguistic needs of the target audience, connects the digitized objects to their respective cultures and contributes to richer descriptive records. The approach that relies on human translation and research can be undertaken in small-scale digitization projects of rare cultural heritage materials. Language and subject expertise are required to create bilingual metadata records. Research limitations/implications – This paper presents the results of a case study. The approach to multilingual access that involves research, and it relies on human translation that can only be undertaken in small-scale projects. Practical implications – This case study of creating parallel records with a combination of translation and vocabulary mapping can be useful for designing similar bilingual digital collections. Social implications – This paper also discusses the obligations of holding institutions in undertaking digital conversion of the cultural heritage materials that originated in other countries, especially in regard to providing metadata records that reflect the language of the originating community. Originality/value – The research and practice in multilingual indexing of cultural heritage materials are very limited. There are no standardized models of how to approach building multilingual digita

(Re)considering Literacy and Linguistic Diversity in a Multicultural Society.

Literacy has traditionally been conceptualized as functional literacy, which is generally defined as the ability to read and write in the majority language. However, this concept has been challenged (Chu 1998, 1999) within our contemporary societies, that are multicultural, multilingual, global and technological. Research has shown that job prosperity and health correlate with the ability to read and write in the national language(s) and to use information and communication technologies (ICTs). Nevertheless, for societies to thrive, I call for a reconsideration of the traditional definition of literacy and a re-imagining of literacy in multicultural communities. Traditional definitions of literacy recognize neither an individual?s literacy in nondominant languages nor differences in literacy levels when engaged in different social circumstances; for example, a sociologist is typically less literate at a physics conference than a sociology one. Literacy is problematized in order to challenge any classification of ethnolinguistic minorities as the “Other,” or “illiterate” (in the dominant language), that then, disenfranchises them. To engage linguistic minorities or others in developing their literacy skills, they cannot continue to be disenfranchised in libraries, education institutions or in wider society and they need to be involved in defining, developing, and using their own literacy. This paper addresses the question: What is literacy and linguistic diversity in a multicultural society? Diverse concepts of literacy from a critical perspective will be examined and a holistic model of literacy is proposed. My Ecological Model of Literacy as Engagement and Transformation defines literacy as the activity of engaging with agreed-upon signs for communication, understanding, and action in an organized, socialized environment. It validates the notion of multiple literacies and literacy as situational and temporal, promotes literacy as an evolving and self-actualization process, and shifts the literacy dialogue from a discourse of skill sets to a discourse of power

A Systematic Literature Review on Image Information Needs and Behaviors

Purpose: With ready access to search engines and social media platforms, the way people find image information has evolved and diversified in the past two decades. The purpose of this paper is to provide an overview of the literature on image information needs and behaviors. Design/methodology/approach: Following an eight-step procedure for conducting systematic literature reviews, the paper presents an analysis of peer-reviewed work on image information needs and behaviors, with publications ranging from the years 1997 to 2019. Findings: Application of the inclusion criteria led to 69 peer-reviewed works. These works were synthesized according to the following categories: research methods, users targeted, image types, identified needs, search behaviors, and search obstacles. The reviewed studies show that people seek and use images for multiple reasons, including entertainment, illustration, aesthetic appreciation, knowledge construction, engagement, inspiration, and social interactions. The reviewed studies also report that common strategies for image searches include keyword searches with short queries, browsing, specialization, and reformulation. Observed trends suggest common deployment of query analysis, survey questionnaires, and undergraduate participant pools to research image information needs and behavior. Originality: At this point, after more than two decades of image information needs research, a holistic systematic review of the literature was long overdue. The way users find image information has evolved and diversified due to technological developments in image retrieval. By synthesizing this burgeoning field into specific foci, this systematic literature review provides a foundation for future empirical investigation. With this foundation set, the paper then pinpoints key research gaps to investigate, particularly the influence of user expertise, a need for more diverse population samples, a dearth of qualitative data, new search features, and information and visual literacies instruction

Translanguaging and Public Service Encounters: Language Learning in the Library

This article explores the information desk of a city library as a site for language learning. Using a linguistic ethnographic approach, the interactions between a customer experience and information assistant and the many library users who approach her information desk were analysed. Findings are that, in addition to providing information about library resources, information desks are sites at which bits and pieces of different languages are taught and learned. Such language teaching and learning episodes created interactions of inclusion and welcome that went far beyond purely transactional information. Rather, language‐related episodes created moments of human contact and engagement, which were upheld through the translanguaging practices of interactants, the disposition and workplace competence of library staff, and the spatial ecology of the information desk. Furthermore, the article contributes to ongoing theoretical debates about translanguaging by noting that normativity and pressure toward uniformity are as much a part of languaging processes as creativity and flexibility. Our definition of translanguaging recognises the opposing pull of centrifugal and centripetal forces. The article ends by asking what schools, and language education, might learn from public libraries in creating arenas that maintain communitarianism, diversity of expression, and the development of civic skills

User experiments with the Eurovision cross-language image retrieval system

In this paper we present Eurovision, a text-based system for cross-language (CL) image retrieval. The system is evaluated by multilingual users for two search tasks with the system configured in English and five other languages. To our knowledge this is the first published set of user experiments for CL image retrieval. We show that: (1) it is possible to create a usable multilingual search engine using little knowledge of any language other than English, (2) categorizing images assists the user's search, and (3) there are differences in the way users search between the proposed search tasks. Based on the two search tasks and user feedback, we describe important aspects of any CL image retrieval system
