Such platforms include e-learning systems which have learning, education and/or training as explicit goals or objectives. They also include search engines, social media platforms, video-sharing platforms, and knowledge sharing environments deployed for work, leisure, inquiry, and personal and professional productivity. The new journal, Information and Learning Sciences, aims to advance our understanding of human inquiry, learning and knowledge-building across such information, e-learning, and socio-technical system contexts.
Design/methodology/approach – This article introduces the journal at its launch under new editorship in January, 2019. The article, authored by the journal co-editors and all associate editors, explores the lineage of scholarly undertakings that have contributed to the journal's new scope and mission, which includes past and ongoing scholarship in the following arenas: Digital Youth, Constructionism, Mutually Constitutive Ties in Information and Learning Sciences, and Searching-as-Learning.
Findings – The article offers examples of ways in which the two fields stand to enrich each other towards a greater holistic advancement of scholarship. The article also summarizes the inaugural special issue contents from the following contributors: Caroline Haythornthwaite; Krista Glazewski and Cindy Hmelo-Silver; Stephanie Teasley; Gary Marchionini; Caroline R. Pitt; Adam Bell, Rose Strickman and Katie Davis; Denise Agosto; Nicole Cooke; and Victor Lee.
Originality/value – The article, this special issue, and the journal in full, are among the first formal and ongoing publication outlets to deliberately draw together and facilitate cross-disciplinary scholarship at this integral nexus. We enthusiastically and warmly invite continued engagement along these lines in the journal’s pages, and also welcome related, and wholly contrary points of view, and points of departure that may build upon or debate some of the themes we raise in the introduction and special issue contents.

In this paper we describe Clarity, a Cross Language Information Retrieval (CLIR) system for English, Finnish, Swedish, Latvian and Lithuanian. Clarity is a fully-fledged retrieval system that supports the user during the whole process of query formulation, text retrieval and document browsing. We address four of the major aspects of Clarity: (i) the user-driven methodology that formed the basis for the iterative design cycle and framework in the project, (ii) the system architecture that was developed to support the interaction and coordination of Clarity's distributed services, (iii) the data resources and methods for query translation, and (iv) the support for Baltic languages. Clarity is an example of a distributed CLIR system built with minimal translation resources and, to our knowledge, the only such system that currently supports Baltic languages.

This chapter discusses CIS from four different perspectives – education, healthcare, science research and patent research. We first introduce the CIS context, focusing on Evans and Chi’s proposed model of social search. We highlight the ways contextual factors relate to the search process, in particular noting the role of communication in CIS processes. The four example professional contexts are discussed with reference to the ‘medium’ of collaboration, the ways CIS is conducted, the tools used and physical setting of CIS, and the ‘context’ of CIS, the purposes for which an instance of CIS occurs in that discipline. We suggest that these contextual factors can be aligned with, but are additional to, the existing Evans and Chi model of social search, and that their addition in a ‘pre- and post-model’ extension could provide a shared framework for researching contextual features of CIS. In highlighting commonalities and contrasts across the disciplinary contexts we suggest that a developed model, and further research, is needed to understand the relationship between motivations in these different disciplines and the evaluation of CIS episodes, and the role of processes, particularly communication, in those episodes. In order to evaluate CIS in different disciplines future research should focus on the between, and within discipline differences in the purposes of CIS. Characteristics of success in different disciplinary contexts may relate both to the consideration of the collaborative context, and the information need; developing deeper understanding of this point.

We varied simulated task context and measured user performance in document assessment task to find that choice of language and task context indeed have effects on the amount of efforts users need to expend to achieve task completion.

Results show that relevance assessment in a foreign language takes more time and is prone to errors compared to assessment in the reader's first language. The results are related to task and context and an enhanced methodology for performing context-sensitive studies is reported. 1.

This year's interactive cross-lingual information access experiment was designed to measure three parameters we expected would affect the performance of users in cross-lingual tasks in languages in which the users are less than fluent. Firstly, introducing new technology, we measure the effect of topic-tailored term expansion on query formulation. Secondly, introducing a new component in the interactive interface, we investigate -without measuring by using a control group -the effect of a bookmark panel on user confidence in the reported result. Thirdly, we ran subjects pair-wise and allowed them to communicate verbally, to investigate how people may cooperate and collaborate with a partner during a search session performing a similar but non-identical search task.

This article considers the concept of task in the context of information studies in order to provide a definitional clarity for task-based information seeking and retrieval studies. We identify (1) the central task levels as well as (2) the kinds of dimensions connected to the levels from the perspective of information studies. The analysis is aimed to serve as a conceptual starting point for empirical studies in the research area. The focus is on some central aspects of tasks that are recognized within information studies as well as related research areas (e.g., organizational studies). We define two levels of information-related subtasks: information seeking tasks and information search tasks. Information retrieval tasks are explicitly considered as a specific type of information search task. We describe differences and connections between these task levels. Finally, the implications of the proposed conceptual framework for information studies are discussed.
