Expected reading effort in focused retrieval evaluation

This study introduces a novel framework for evaluating passage and XML retrieval. The framework focuses on a user’s effort to localize relevant content in a result document. Measuring the effort is based on a system guided reading order of documents. The effort is calculated as the quantity of text the user is expected to browse through. More specifically, this study seeks evaluation metrics for retrieval methods following a specific fetch and browse approach, where in the fetch phase documents are ranked in decreasing order according to their document score, like in document retrieval. In the browse phase, for each retrieved document, a set of non-overlapping passages representing the relevant text within the document is retrieved. In other words, the passages of the document are re-organized, so that the best matching passages are read first in sequential order. We introduce an application scenario motivating the framework, and propose sample metrics based on the framework. These metrics give a basis for the comparison of effectiveness between traditional document retrieval and passage/XML retrieval and illuminate the benefit of passage/XML retrieval.

Scenarios in information seeking and information retrieval research: A methodological application and discussion

Scenario has been used as a research tool to study information seeking and information retrieval. This review of the nature and development of scenario use reveals a variety of applications and a number of practical methodological issues. While scenarios have a number of advantages, there are limitations. Consideration of these advantages and challenges leads to recommendations for constructing and presenting scenarios.     

Current research issues and trends in non-English Web searching

With increasingly higher numbers of non-English language web searchers the problems of efficient handling of non-English Web documents and user queries are becoming major issues for search engines.

Overlaps of multiple database retrieval and citation tracking in dementia care research: a methodological study

Objective:We aimed to determine overlaps and optimal combination of multiple database retrieval and citation tracking for evidence synthesis, based on a previously conducted scoping review on facilitators and barriers to implementing nurse-led interventions in dementia care.Methods:In our 2019 scoping review, we performed a comprehensive literature search in eight databases (CENTRAL, CINAHL, Embase, Emcare, MEDLINE, Ovid Nursing Database, PsycINFO, and Web of Science Core Collection) and used citation tracking. We retrospectively analyzed the coverage and overlap of 10,527 retrieved studies published between 2015 and 2019. To analyze database overlap, we used cross tables and multiple correspondence analysis (MCA).Results:Of the retrieved studies, 6,944 were duplicates and 3,583 were unique references. Using our search strategies, considerable overlaps can be found in some databases, such as between MEDLINE and Web of Science Core Collection or between CINAHL, Emcare, and PsycINFO. Searching MEDLINE, CINAHL, and Web of Science Core Collection and using citation tracking were necessary to retrieve all included studies of our scoping review.Conclusions:Our results can contribute to enhancing future search practice related to database selection in dementia care research. However, due to limited generalizability, researchers and librarians should carefully choose databases based on the research question. More research on optimal database retrieval in dementia care research is required for the development of methodological standards.     

A scoping review of individual differences in information seeking behavior and retrieval research between 2000 and 2015

Individual differences have long been of interest in information science as they bear on the design of information systems and services for specific populations. Yet little is known as to which individual differences make a difference to search outcomes, both across applications and for diverse user groups. A scoping study of information seeking and retrieval research from 2000 to 2015 was conducted. Over 2100 articles retrieved from eight scholarly databases were screened based on title, abstract, and full-text (using specified inclusion criteria), resulting in 223 papers for analysis. Data were extracted to provide an overview of the literature, including types of individual differences studied, publication volume over time, measures, samples, and study outcomes. Findings are inconclusiveness regarding how individual differences affect search outcomes, and raise issues around measurement and generalizability. This study represents an essential first step to developing a more systematic investigation of individual differences research and connecting individual research studies to anchor and guide future work.

Topics in dynamic research communities: An exploratory study for the field of information retrieval

Research topics and research communities are not disconnected from each other: communities and topics are interwoven and co-evolving. Yet, scientometric evaluations of topics and communities have been conducted independently and synchronically, with researchers often relying on homogeneous unit of analysis, such as authors, journals, institutions, or topics. Therefore, new methods are warranted that examine the dynamic relationship between topics and communities. This paper examines how research topics are mixed and matched in evolving research communities by using a hybrid approach which integrates both topic identification and community detection techniques. Using a data set on information retrieval (IR) publications, two layers of enriched information are constructed and contrasted: one is the communities detected through the topology of coauthorship network and the other is the topics of the communities detected through the topic model. We find evidence to support the assumption that IR communities and topics are interwoven and co-evolving, and topics can be used to understand the dynamics of community structures. We recommend the use of the hybrid approach to study the dynamic interactions of topics and communities.     

From retrieval to robotics: The national science foundation's support of information research

This article describes how the National Science Foundation's support of information research has evolved from NSF's original mission of improving the dissemination of scientific and technical information to its present interest in information robotics and intelligent systems. The pattern of grant support, since a major reorganization of the information science division in 1978, is analyzed in terms of the institutions, the investigators, and the disciplines that have been major grant recipients.
