Abstract

The study assessed the ability of children to categorise concepts that will be used to organise an information retrieval interface. The work was done of Project SEED (Science for Early Educational Development), a project to develop hands-on science programmes for elementary schools. Aims to tailor an interface to the particular skills of children in organising science knowledge. The results are promising for the design of IR interfaces based on children's abilities to manipulate information.

Abstract

We return to arguments made 10 years ago that online catalogs are difficult to use because their design does not incorporate sufficient understanding of searching behavior. The earlier article examined studies of information retrieval system searching for their implications for online catalog design; this article examines the implications of card catalog design for online catalogs. With this analysis, we hope to contribute to a better understanding of user behavior and to lay to rest the card catalog design model for online catalogs. We discuss the problems with query matching systems, which were designed for skilled search intermediaries rather than end-users, and the knowledge and skills they require in the information-seeking process, illustrated with examples of searching card and online catalogs. Searching requires conceptual knowledge of the information retrieval process - translating an information need into a searchable query; semantic knowledge of how to implement a query in a given system - the how and when to use system features; and technical skills in executing the query - basic computing skills and the syntax of entering queries as specific search statements. In the short term, we can help make online catalogs easier to use through improved training and documentation that is based on information-seeking bahavior, with the caveat that good training is not a substitute for good system design. Our long term goal should be to design intuitive systems that require a minimum of instruction. Given the complexity of the information retrieval problem and the limited capabilities of today's systems, we are far from achieving that goal. If libraries are to provide primary information services for the networked world, they need to put research results on the information-seeking process into practice in designing the next generation of online public access information retrieval systems

Abstract

Searching information retrieval systems is a highly interactive, iterative process that cannot be understood simply by comparing the output of a search session (the 'search product') to a query stated in advance. In this article, we examine evaluation goals and methods for studying information retrieval behavior, drawing examples from our own research and that of others. We limit our review to research that employs online monitoring, also known as transaction log analysis. Online monitoring is one of few methods that can capture detailed data on the search process at a reasonable cost; these data can be used to build quantitative models or to support qualitative interpretations of quatitative results. Monitoring is a data collection technique rather than a research design, and can be employed in experimental of field studies, whether alone or combined with other data collection methods. Based on the the research questions of interest, the researcher must determine what variables to collect from each data source, which to treat as independent varaibles to manipulate, and which to treat as dependent variables to observe effects. Studies of searching behavior often treat search task and searcher characteristics as independent variables and may manipulate other independent variables specific to the research questions addressed. Search outcomes, time, and search paths frequently are treated as dependent variables. We discuss each of these sets of variables, illustrating them with sample results from the literature and from our own research. Our examples are drawn from the Science Library Catalog project, a 7-year study of children's searching behavior on an experimental retrieval system. We close with a brief discussion of the implications of these results for the design of information retrieval systems

Abstract

Research in user behavior on online catalogs is in its early stages, but preliminary findings suggest that users encounter many of the same problems identified in behavioral studies of other types of bibliographic retrieval systems. Much can be learned from comparing the results of user behavior studies on these two types of systems. Research on user problems with both the mechanical aspects and the conceptual aspects of system use is reviewed, with the conclusion that more similiratiy exists across types of systems in conceptual than in mechanical problems. Also discussed are potential sources of the problems, due either to individual characteristics or to system variables. A series of research questions is proposed and a number of potential interim solutions ae suggested for alleviating some of the problems encountered by users of information systems

Abstract

As we seek both to improve public school education in high technology areas and to link libraries and classrooms on the 'information superhighway', we need to understand more about children's information searching abilities. We present results of 4 experiments conducted on 4 versions of the Science Library Catalog (SLC), a Dewey Decimal based hierarchical browsing systems implemeted in HyperCard without a keyboard. The experiments were conducted over a 3-year period at 3 sites, with 4 databases, and with comparisons to 2 different keyword online catalogs. Subjects were ethnically and culturally diverse children aged 9 through 12; with 32 to 34 children participating in each experiment. Children were provided explicit instruction and reference materials for the keyword systems but not for the SLC. The number of search topics matched was comparable across all systems and all experiments; search times were comparable, thought hey varied among the 4 SLC versions and between the 2 keyword OPACs. The SLC overall was robust to differences in age, sex and computer experience. One of the keyword OPACs was subject to minor effects of age and computer experience; the other was not. We found relationships between search topic and system structure, such that the most difficult topics on the SLC were those hard to locate in the hierarchy, and those most difficult on the keyword OPACs were hard to spell or required children to generate their own search terms. The SLC approach overcomes problems with several searching features that are difficult for children in typical keyword OPAC systems; typing skills, spelling, vocabulary, and Boolean logic. Results have general implications for the desing of information retrieval systems for children
