Search results

This paper compares and contrasts online searching on DataStar, a major European host now owned by The Dialog Corporation, using the “Classic” command language, with access via the more recent Web interface. DataStar, established in 1981, was one of the first online hosts to offer a web interface, in December 1996. DataStar Web was upgraded in December 1997. “Classic” DataStar command line searching requires familiarity with commands, operators, database labels, etc. DataStar Web offers searching via apparently simple steps: eg. selecting a database, entering search terms. The functionality of the two interfaces is considered, looking in turn at entering the system, selecting a database, searching, output and display, terminating the search session, error messages and help pages, and support, training and documentation. The search functionality of the two interfaces is not identical, although both use the same retrieval software and access the same databases. Many of the differences affect retrieval effectiveness and may trip up novice and experienced searchers alike.

This paper reports the results of a study funded by the Arts and Humanities Research Board which sought to investigate links between Web search strategies and retrieval effectiveness. A total of 68 students, enrolled on masters programmes in librarianship, information management and information systems, searched for two topics using the AltaVista search engine. Logs of the resultant 341 queries, along with relevance judgements for over 4,000 retrieved items, were analysed using factor analysis and regression. The differing but complementary types and strengths of evidence produced by these two forms of analysis are discussed and presented. Retrieval effectiveness was associated positively with best‐match searching and negatively with Boolean searching. The implications of these findings for Web searching are discussed.

The study aims to paint a representative picture of the current state of search interfaces of Swedish online museum collections, focussing on search functionalities with particular reference to subject searching, as well as the use of controlled vocabularies, with the purpose of identifying which improvements of the search interfaces are needed to ensure high-quality information retrieval for the end user.

In the first step, a set of 21 search interface criteria was identified, based on related research and current standards in the domain of cultural heritage knowledge organization. Secondly, a complete set of Swedish museums that provide online access to their collections was identified, comprising nine cross-search services and 91 individual museums' websites. These 100 websites were each evaluated against the 21 criteria, between 1 July and 31 August 2020.

Although many standards and guidelines are in place to ensure quality-controlled subject indexing, which in turn support information retrieval of relevant resources (as individual or full search results), the study shows that they are not broadly implemented, resulting in information retrieval failures for the end user. The study also demonstrates a strong need for the implementation of controlled vocabularies in these museums.

This study is a rare piece of research which examines subject searching in online museums; the 21 search criteria and their use in the analysis of the complete set of online collections of a country represents a considerable and unique contribution to the fields of knowledge organization and information retrieval of cultural heritage. Its particular value lies in showing how the needs of end users, many of which are documented and reflected in international standards and guidelines, should be taken into account in designing search tools for these museums; especially so in subject searching, which is the most complex and yet the most common type of search. Much effort has been invested into digitizing cultural heritage collections, but access to them is hindered by poor search functionality. This study identifies which are the most important aspects to improve.

The aims of this study were to identify the retrieval features for online databases; difficulties faced by users; and retrieval features expected by users. A total of 25 databases were surveyed and 40 users were interviewed after the training sessions. Common retrieval features included Boolean operators, phrase searching, match of exact words or phrases, field specific and limit fields searches, truncation, and wildcard. Even though features are offered in many systems, their interpretation and implementation are different. Unique features included lateral searching, density and frequency of terms, reference link, and searching via table of content. The expected features included relevance feedback and term weighting other than those already offered by ACM Digital Library and IEEE Xplore. Such expectations were influenced by the users' background in ICT. Difficulties included application of the retrieval features in searching. Database providers must include the expected features, synonyms linked to terms in the thesaurus, and extensive search examples.

The purpose of this paper is to determine whether features of next-generation Online Public Access Catalogue (OPAC) interfaces are useful and intuitive to users who have different levels of searching ability. In addition, it investigates whether there is a difference between librarians’ and students’ preferences for specific features.

The research is based on 18 semi-structured interviews conducted in July 2012 with three groups of library users from The University of Sheffield: librarians; Master of Arts Librarianship students; and a group of other post-graduate students.

Overall, this study suggests that while the next-generation catalogue interfaces and features are useful, they are not as “intuitive” as some previous studies have claimed. Interviewees appeared to prefer the searching and browsing options over the Web 2.0 features. Both librarians and students have similar opinions regarding the usefulness of next-generation OPAC features, but preferences are complex.

The study is based on one institution, and the disciplinary background of the post-graduate students was limited.

Promoting next generation OPACs and explaining their features to users is essential.

The paper adds to the understanding of users’ preferences in relation to next-generation OPACs, locating the findings of the current findings firmly in the context of previous literature.

This exploratory study aims to help contribute to the understanding of online information search behaviour of PhD students from different humanities fields, with a focus on subject searching.

The methodology is based on a semi-structured interview within which the participants are asked to conduct both a controlled search task and a free search task. The sample comprises eight PhD students in several humanities disciplines at Linnaeus University, a medium-sized Swedish university from 2020.

Most humanities PhD students in the study have received training in information searching, but it has been too basic. Most rely on web search engines like Google and Google Scholar for publications' search, and university's discovery system for known-item searching. As these systems do not rely on controlled vocabularies, the participants often struggle with too many retrieved documents that are not relevant. Most only rarely or never use disciplinary bibliographic databases. The controlled search task has shown some benefits of using controlled vocabularies in the disciplinary databases, but incomplete synonym or concept coverage as well as user unfriendly search interface present hindrances.

The paper illuminates an often-forgotten but pervasive challenge of subject searching, especially for humanities researchers. It demonstrates difficulties and shows how most PhD students have missed finding an important resource in their research. It calls for the need to reconsider training in information searching and the need to make use of controlled vocabularies implemented in various search systems with usable search and browse user interfaces.

This paper aims to introduce a prototype system called SAFQuery (Simple And Flexible Query interface). In many existing Web search interfaces, simple and advanced query processes are treated separately that cannot be issued interchangeably. In addition, after several rounds of queries for specific information need(s), it is possible that users might wish to re-examine the retrieval results corresponding to some previous queries or to slightly modify some of the specific queries issued before. However, it is often hard to remember what queries have been issued. These factors make the current Web search process not very simple or flexible.

In SAFQuery, the simple and advanced query strategies are integrated into a single interface, which can easily formulate query specifications when needed in the same interface. Moreover, query history information is provided that displays the past query specifications, which can help with the memory load.

The authors' experiments by user evaluation show that most users had a positive experience when using SAFQuery. Specifically, it is easy to use and can simplify the Web search task.

The proposed prototype system provides simple and flexible Web search strategies. Particularly, it allows users to easily issue simple and advanced queries based on one single query interface, interchangeably. In addition, users can easily input previously issued queries without spending time to recall what the queries are and/or to re-type previous queries.

The purpose of this paper is to explore educational researchers’ online literature searching and sourcing strategies.

Adopting a multiple-case study approach, the authors conducted interviews and compared strategies employed by three groups of researchers: less-experienced doctoral students, experienced doctoral students, and junior faculty.

The results showed that the three groups differed in four searching strategies and two sourcing strategies. The former included: using and modifying keywords, doing advanced searches to narrow down or expand results, chaining, and networking to retrieve literature, while the latter consisted of: evaluating and selecting multiple-source articles, and self-monitoring the multiple-source searching process. The findings also revealed that the experienced doctoral students and junior faculty were able to adopt searching and sourcing strategies flexibly and simultaneously for the purpose of determining more relevant and useful sources. The findings suggest that these researchers, especially the less-experienced students, need specialized training to acquire sourcing strategies in order to critically evaluate relevant information or scholarly work to fulfill their research purposes.

Information seeking, an essential part of scholars’ work, has been widely examined across disciplines. However, few studies have explored scholars’ searching and sourcing behaviors for online academic literature. This study fulfilled the research gap.

The purpose of this paper is to compare the efficacy of two approaches to finding articles on a topic by measuring student perceptions of the ease‐of‐use of the search process and the perceived relevancy of search results retrieved using both a single multidisciplinary database and a federated search tool.

Students are asked to search both a federated search tool and a single multidisciplinary database, record their searches and respond to a series of quantitative and qualitative questions regarding their experiences with searching both search tools.

Study results indicate a slight preference for federated searching over single database searching based on perceived relevancy of results and likeliness of future use. Study data supports equal promotion of single database searching and federated searching to undergraduate students.

The results of this paper have practical implications for reference and instruction librarians teaching undergraduate students and library users in general to find the most effective, efficient and manageable approach to finding articles on a topic.

Previous research comparing federated searching to other research methods uses prescribed topics outside of an actual class setting, while this is a naturalistic study in which students searched for articles on a research topic of their own choosing for a required research assignment. A previous study compared federated searching to navigating and searching numerous databases. This paper compares a federated search tool to a single multidisciplinary database.

Web‐based online public access catalogues (OPACs) began to appear in the late 1990s and many libraries are currently considering implementation. As catalogues, they demonstrate advances on traditional OPACs, especially in terms of remote access by users and their potential to integrate many document types and sources via a single interface. This paper considers some of the features and functions of Web OPAC interfaces. As yet, very little evaluation of systems and users has taken place and until more such literature appears, a general approach to products available is considered to be of value. Six popular Web OPAC interfaces in use in UK academic libraries (Talis, INNOPAC, WebCat, Voyager, GeoWeb and ALEPH) have been examined with an overview of the functions offered via those interfaces. A checklist has been developed as an indicator of the important features and functions offered.
