- Abstract
- What is the difference between Piaget's constructivism and Papert's "constructionism"? Beyond the mere play on the words, I think the distinction holds, and that integrating both views can enrich our understanding of how people learn and grow. Piaget's constructivism offers a window into what children are interested in, and able to achieve, at different stages of their development. The theory describes how children's ways of doing and thinking evolve over time, and under which circumstance children are more likely to let go of-or hold onto- their currently held views. Piaget suggests that children have very good reasons not to abandon their worldviews just because someone else, be it an expert, tells them they're wrong. Papert's constructionism, in contrast, focuses more on the art of learning, or 'learning to learn', and on the significance of making things in learning. Papert is interested in how learners engage in a conversation with [their own or other people's] artifacts, and how these conversations boost self-directed learning, and ultimately facilitate the construction of new knowledge. He stresses the importance of tools, media, and context in human development. Integrating both perspectives illuminates the processes by which individuals come to make sense of their experience, gradually optimizing their interactions with the world.

- Abstract
- In this lecture I intend to challenge those who uphold a monist or even a dualist view of the universe; and I will propose, instead, a pluralist view. I will propose a view of the universe that recognizes at least three different but interacting sub-universes.

- Abstract
- Author research impact was examined based on citer analysis (the number of citers as opposed to the number of citations) for 90 highly cited authors grouped into three broad subject areas. Citer-based outcome measures were also compared with more traditional citation-based measures for levels of association. The authors found that there are significant differences in citer-based outcomes among the three broad subject areas examined and that there is a high degree of correlation between citer and citation-based measures for all measures compared, except for two outcomes calculated for the social sciences. Citer-based measures do produce slightly different rankings of authors based on citer counts when compared to more traditional citation counts. Examples are provided. Citation measures may not adequately address the influence, or reach, of an author because citations usually do not address the origin of the citation beyond self-citations.

- Abstract
- Pauline Atherton Cochrane has been contributing to library and information science for fifty years. Think of it-from mid-century to the millennium, from ENIAC (practically) to Internet 11 (almost here). What a time to be in our field! Her work an indexing, subject access, and the user-oriented approach had immediate and sustained impact, and she continues to be one of our most heavily cited authors (see, JASIS, 49[4], 327-55) and most beloved personages. This introduction includes a few words about my own experiences with Pauline as well as a short summary of the contributions that make up this tribute. A review of the curriculum vita provided at the end of this publication Shows that Pauline Cochrane has been involved in a wide variety of work. As Marcia Bates points out in her note (See below), Pauline was (and is) a role model, but I will always think of her as simply the best teacher 1 ever had. In 1997, I entered the University of Illinois Graduate School of Library and Information Science as a returning mid-life student; my previous doctorate had not led to a full-time job and I was re-tooling. I was not sure what 1 would find in library school, and the introductory course attended by more than 100 students from widely varied backgrounds had not yet convinced me I was in the right place. Then, one day, Pauline gave a guest lecture an the digital library in my introductory class. I still remember it. She put up some notes-a few words clustered an the blackboard with some circles and directional arrows-and then she gave a free, seemingly extemporaneous, but riveting narrative. She set out a vision for ideal information exchange in the digital environment but noted a host of practical concerns, issues, and potential problems that required (demanded!) continued human intervention. The lecture brought that class and the entire semester's work into focus; it created tremendous excitement for the future of librarianship. 1 saw that librarians and libraries would play an active role. I was in the right place.

- Abstract
- Purpose With the shift to an information-based society and to the de-centralisation of information, information overload has attracted a growing interest in the computer and information science research communities. However, there is no clear understanding of the meaning of the term, and while there have been many proposed definitions, there is no consensus. The goal of this work was to define the concept of "information overload". In order to do so, a concept analysis using Rodgers' approach was performed. Design/methodology/approach A concept analysis using Rodgers' approach based on a corpus of documents published between 2010 and September 2020 was conducted. One surrogate for "information overload", which is "cognitive overload" was identified. The corpus of documents consisted of 151 documents for information overload and ten for cognitive overload. All documents were from the fields of computer science and information science, and were retrieved from three databases: Association for Computing Machinery (ACM) Digital Library, SCOPUS and Library and Information Science Abstracts (LISA). Findings The themes identified from the authors' concept analysis allowed us to extract the triggers, manifestations and consequences of information overload. They found triggers related to information characteristics, information need, the working environment, the cognitive abilities of individuals and the information environment. In terms of manifestations, they found that information overload manifests itself both emotionally and cognitively. The consequences of information overload were both internal and external. These findings allowed them to provide a definition of information overload. Originality/value Through the authors' concept analysis, they were able to clarify the components of information overload and provide a definition of the concept.

- Abstract
- To date, there has been little empirical research investigating the specific types of help-seeking situations that arise when people interact with information in new searching environments such as digital libraries. This article reports the results of a project focusing on the identification of different types of help-seeking situations, along with types of factors that precipitate them among searchers of two different digital libraries. Participants (N = 120) representing the general public in Milwaukee and New York City were selected for this study. Based on the analysis of multiple sources of data, the authors identify 15 types of help-seeking situations among this sample of novice digital library users. These situations are related to the searching activities involved in getting started, identifying relevant digital collections, browsing for information, constructing search statements, refining searches, monitoring searches, and evaluating results. Multiple factors that determine the occurrences of each type of help-seeking situation also are identified. The article concludes with a model that represents user, system, task, and interaction outcome as codeterminates in the formation of help-seeking situations, and presents the theoretical and practical implications of the study results.

- Abstract
- In the keynote paper for the 12th International ISKO Conference in Mysore I discussed the dynamicity of the domain of knowledge organization from the perspective of ongoing domain analyses. Metaanalysis of a series of studies shows that knowledge organization is a strong, scientific community, with a distinct extension that now embraces the search for interoperability, and with intension that shifts along two continuums, one of which is methodological (or epistemological) and ranges from empirical experimental methods to humanistic narrative methods, while the other is more contextual and ranges from concept theory to applied KOS. These elements seem to remain core in knowledge organization as a domain over time (Smiraglia 2012). Another interesting finding is the degree to which the intension along that theory-application continuum is stretched by papers presented at regional ISKO chapter conferences. Since 2006 it has been the policy of this journal to offer to publish the leading papers from any peer-reviewed regional ISKO conference. The papers are selected by conference organizers and forwarded to Knowledge Organization for publication. By analyzing the papers separately we are able to see both the presence of the domain's core internationally and the constant tug and pull on the intension as authors bring new ideas and new research to regional conferences. This editorial, then, summarizes papers from regional conferences that have appeared in Knowledge Organization in 2011 and 2012.

- Abstract
- I analyze the text of an article that appeared in this journal in 2007 that published the results of a questionnaire in which a number of experts were asked to define the concepts of data, information, and knowledge. I apply standard information retrieval techniques to build a list of the most frequent terms in each set of definitions. I then apply information extraction techniques to analyze how the top terms are used in the definitions. As a result, I draw data-driven conclusions about the aggregate opinion of the experts. I contrast this with the original analysis of the data to provide readers with an alternative viewpoint on what the data tell us.

- Abstract
- Ahlgren, Jarneving, and. Rousseau review accepted procedures for author co-citation analysis first pointing out that since in the raw data matrix the row and column values are identical i,e, the co-citation count of two authors, there is no clear choice for diagonal values. They suggest the number of times an author has been co-cited with himself excluding self citation rather than the common treatment as zeros or as missing values. When the matrix is converted to a similarity matrix the normal procedure is to create a matrix of Pearson's r coefficients between data vectors. Ranking by r and by co-citation frequency and by intuition can easily yield three different orders. It would seem necessary that the adding of zeros to the matrix will not affect the value or the relative order of similarity measures but it is shown that this is not the case with Pearson's r. Using 913 bibliographic descriptions form the Web of Science of articles form JASIS and Scientometrics, authors names were extracted, edited and 12 information retrieval authors and 12 bibliometric authors each from the top 100 most cited were selected. Co-citation and r value (diagonal elements treated as missing) matrices were constructed, and then reconstructed in expanded form. Adding zeros can both change the r value and the ordering of the authors based upon that value. A chi-squared distance measure would not violate these requirements, nor would the cosine coefficient. It is also argued that co-citation data is ordinal data since there is no assurance of an absolute zero number of co-citations, and thus Pearson is not appropriate. The number of ties in co-citation data make the use of the Spearman rank order coefficient problematic.
