- Abstract
- Case records of patients with brain tumours and the related image files (CATSCAN, MRI, X-ray, etc.) are information products generated and used by surgeons. A system has been developed to navigate within case records and link an to related image files. Hypertext links to relevant Web resources an brain tumours are also provided for from the case records. The collaborative and semantic dimensions of the knowledge base development are mentioned. Some 20 fields record administrative data and some 160 fields describe the characteristics of the tumour, its diagnosis, surgery, post-surgical complications, etc. This knowledge base forms part of a total system that includes three other databases of case sheets of patients (with tumours of the pituitary, spinal cord, and trauma), a bibliographic database, profiles of institutions, experts and projects.

- Abstract
- Can we 'see' or 'find' consciousness in the brain? How can we create working definitions of consciousness and subjectivity, informed by what contemporary research and technology have taught us about how the brain works? How do neuronal processes in the brain relate to our experience of a personal identity?To explore these and other questions, Georg Northoff turns to examples of unhealthy minds. By investigating consciousness through its absence in a vegetative state, for example, we can develop a model for understanding its presence in an active, healthy person. By examining instances of distorted self-recognition in people with psychiatric disorders, like schizophrenia, we can begin to understand how the experience of ?self? is established in a stable brain.Taking an integrative approach to understanding the self, consciousness, and what it means to be mentally healthy, this book brings insights from neuroscience to bear on philosophical questions.

- Abstract
- The representation of information contents by graphical maps is an extended ongoing research topic. In this paper we introduce the application of UDC codes for the subject maps development. We use the following graphic representation methodologies: 1) Multidimensional scaling (MDS), 2) Cluster analysis, 3) Neural networks (Self Organizing Map - SOM). Finally, we conclude about the application viability of every kind of map. 1. Introduction Advanced techniques for Information Retrieval (IR) currently make up one of the most active areas for research in the field of library and information science. New models representing document content are replacing the classic systems in which the search terms supplied by the user were compared against the indexing terms existing in the inverted files of a database. One of the topics most often studied in the last years is bibliographic browsing, a good complement to querying strategies. Since the 80's, many authors have treated this topic. For example, Ellis establishes that browsing is based an three different types of tasks: identification, familiarization and differentiation (Ellis, 1989). On the other hand, Cove indicates three different browsing types: searching browsing, general purpose browsing and serendipity browsing (Cove, 1988). Marcia Bates presents six different types (Bates, 1989), although the classification of Bawden is the one that really interests us: 1) similarity comparison, 2) structure driven, 3) global vision (Bawden, 1993). The global vision browsing implies the use of graphic representations, which we will call map displays, that allow the user to get a global idea of the nature and structure of the information in the database. In the 90's, several authors worked an this research line, developing different types of maps. One of the most active was Xia Lin what introduced the concept of Graphical Table of Contents (GTOC), comparing the maps to true table of contents based an graphic representations (Lin 1996). Lin applies the algorithm SOM to his own personal bibliography, analyzed in function of the words of the title and abstract fields, and represented in a two-dimensional map (Lin 1997). Later on, Lin applied this type of maps to create websites GTOCs, through a Java application.

- Abstract
- What exactly are the Wellsian World Brain or World Encyclopedia ideas to which reference is so often made? What did they mean for Wells? What might they mean for us? This article examines closely what Wells says about them in his book, World Brain (1938), and in a number of works that elaborate what is expressed there. The article discusses aspects of the context within which Wells's conception of a new world encyclopedia organization was formulated and its role in the main trust of his thought. The article argues that Wells's ideas about a World Brain are embedded in a strucutre of thought that may be shown to entail on the one hand notions of social repression and control that must give us pause, and on the other a concept of the nature and organization of knowledge that may well be no longer acceptable. By examining Wells's ideas in some detail and attempting to articulate the systems of belief which shaped tham and which otherwise lie silent beneath them, the author hopes to provoke questions about current theorizing about the nature of global information systems and emergent intelligence

- Abstract
- The purpose of this work is to develop an ontology-based framework for developing an information retrieval system to cater to specific queries of users. For creating such an ontology, information was obtained from a wide range of information sources involved with brain tumour study and research. The information thus obtained was compiled and analysed to provide a standard, reliable and relevant information base to aid our proposed system. Facet-based methodology has been used for ontology formalization for quite some time. Ontology formalization involves different steps such as identification of the terminology, analysis, synthesis, standardization and ordering. A vast majority of the ontologies being developed nowadays lack flexibility. This becomes a formidable constraint when it comes to interoperability. We found that a facet-based method provides a distinct guideline for the development of a robust and flexible model concerning the domain of brain tumours. Our attempt has been to bridge library and information science and computer science, which itself involved an experimental approach. It was discovered that a faceted approach is really enduring, as it helps in the achievement of properties like navigation, exploration and faceted browsing. Computer-based brain tumour ontology supports the work of researchers towards gathering information on brain tumour research and allows users across the world to intelligently access new scientific information quickly and efficiently.

- Abstract
- The central problem with understanding brain and mind is the neural code issue: understanding the matter of our brain as basis for the phenomena of our mind. The richness with which our mind represents our environment, the parsimony of genetic data, the tremendous efficiency with which the brain learns from scant sensory input and the creativity with which our mind constructs mental worlds all speak in favor of mind as an emergent phenomenon. This raises the further issue of how the neural code supports these processes of organization. The central point of this communication is that the neural code has the form of structured net fragments that are formed by network self-organization, activate and de-activate on the functional time scale, and spontaneously combine to form larger nets with the same basic structure.

- Rez. in: KO 32(2005) no.3, S.135-136 (N. Bridge): "Authors of books have usually lived with their material for years before they embark on the arduous business of writing the book, followed by the revisiting during the editing and publishing processes. The indexers of their books usually have between two and four weeks to absorb the subject of the book. Even with a prior knowledge of the discipline, they are faced with the author's particular "take" on the subject and writing style, including any one of a number of ways of presenting the material. This is multiplied in complexity when the book is a multiauthored work, a collection of essays and papers, comprising several authors' differing views and individual styles. Ideally, the indexer is an expert in the subject matter of the book, perfectly matched to the book; in practice, this almost never happens. Indexers aim at producing an index that is truly reflective of the individual book and its author, a goal that often seems overwhelming when the pile of page proofs arrives with the courier, or electronically through a PDF file, hundreds of pages of closely argued text. As well as the time limit, there can be other restrictions, most commonly having to make the index fit into the number of pages decreed by the publisher, with difficult, even agonizing decisions lying ahead. Consequently, indexers can fall into a number of different traps: getting lost in a welter of detailed overindexing; or, mindful of time and space limits, indexing too broadly and simplistically, bouncing from text heading to heading, topic sentence to topic sentence. Most indexers of academic books I know, including myself, tend to fall into the first category at least with their first few indexes. Especially when the content is personally fascinating, it's easy to lose a rational, analytical approach to the content of a book, and wrest this back only with difficulty during the editing stage with the deadline looming. Do Mi Stauber's title, Facing the Text, is, thus, provocative, because that's what all indexers inevitably have to do. She knows the process: for example, at the start, the "gap between you and those pages that for a moment seems very wide" (p. 1). This sympathetic, personal tone pervades the book: the emphasis is on the personal experiences, feelings, and perceptions of indexers when confronted by the various situations thrown up by indexing; it's "I" and "you" throughout. The chapter subheadings often echo this: my tendency to lose sight of main topics is explained and diagnosed in "Lost Among the Trees" (p. 63-64). The section "Being Stuck" (p. 324-26), describes a number of reasons for this common malady, along with remedies for each, including the "Hammock Method" (p. 46). Stauber has been presenting workshops with the title "Facing the Text" since 1997, and her book reflects a friendly, listening engagement with her audience.
She divides the topics within the text to be indexed into the categories of metatopics, local main topics, and ancillary topics, followed by subheadings. The indexability of individual topics at whatever level, and their wording, absorb other chapters. Linkages among the topics - cross-references and doubleposting - arc tracked in the chapter "Connections and Access." Finally, the mechanics of indexing are contained in "Process" and "Inside an Indexer's Brain" describes her own procedure and feelings as she indexes a book from beginning to end. When I initially faced the text of this book, I felt overwhelmed, even bewildered, by the plethora of terminology, much of it Stauber's own. Further, each chapter is divided into a complex array of headings, subheadings, sub-subheadings, and more. But when I read from beginning to end, all those pieces fell into place. Stauber develops her text logically, explaining each step of the way clearly, distinguishing each detail from others, and frequently linking passages to relevant others. At every stage in the book, she illustrates with copious examples from indexes she or others have compiled. In the case of her own indexes, she describes her thought processes, her initial reactions to what she read, her decisions regarding the use of particular topics and at what level, and of her chosen terminology; and also, and often, how and why she later changed her mind as she got further into the text. This forms a candid and detailed analysis of indexing, step by step, stage by stage, complex and subtle but with a perceptibly firm connecting structure. In short, she's a good writer.
Facing the Text falls into what I call the third wave of books about back-of-the-book indexing. Each of these waves overlaps, but generally the first consists of the general manuals on indexing books (and other media): Booth, Knight, Mulvany, and Wellisch, along with chapter 18 of the Chicago Manual of Style, 15th ed. These set out the fundamental principles, conventions, or rules of indexing in a mostly impersonal, dispassionate tone. The second wave carried manuals on indexing in specific disciplines and genres: biography, medicine, law, psychology, history, genealogy, etc. The third wave, exemplified by Stauber's Facing the Text and Smith and Kells' Inside Indexing, delves into what goes through the mind of the indexer "facing the text" and putting together an index based on it. The tone is personal and subjective, the authors taking the reader through their own perceptions of the stages of indexing a book, the inevitable problems and subsequent decision making, expressed through their own reactions and reasoning. Facing the Text is not a manual where the newcomer to indexing can find immediate answers to specific problems: the first and second waves of books on indexing are designed to provide those. It's a book for the professional indexer or academic author indexing more than one book; its effect is to hone skills and refine working habits, to increase efficiency and effectiveness, to create indexes that make faithful, logical sense of the text. Newcomers, including first-time academic-author indexers, should begin with the last chapter "Inside an Indexer's Brain," then the second-to-last chapter, "Process"; in fact, I would suggest that any reader begin with "Inside an Indexer's Brain," for its introduction to the terminology and the overall look at indexing, from the first to the last page of the text to be indexed. As one would expect, the index to Facing the Text is comprehensive; in fact, exhaustive, and admirably detailed. The personable, conversational tone continues here, with entries such as "Subheadings/creating as you go" and "Notes to yourself." Of course, "Being stuck" is there as is, and also helpfully doubleposted as "Stuckness strategies." Finally, and on a relatively small note, this is a nicely designed book. Not only is it laid out for looks, it's laid out for use. The type is a friendly size, and the complex structure of headings, subheadings, and sub-subheadings is rendered immediately intelligible by the well-chosen fonts. My only criticism concerns the tightness of the binding; manuals should lie flat, without having to be anchored on each side with paperweights."

- Abstract
- The results of diagnostic survey showing the way in which the students of pedagogy create and organize their digital personal environment, used in individual learning process were presented in the paper. 272 students of Cracow schools were covered by the survey. It has been analyzed the sources of information they mostly used, ways of storage, organizing and aggregating of information and the tools used for this purpose. The ability to design and build a digital personal learning environment (PLE) is in today's world a very important element of lifelong learning and enables efficient functioning in the information society.

- Abstract
- Argues that Beghtol's (2003) use of the terms "naive classification" and "professional classification" is valid because they are nominal definitions and that the distinction between these two types of classification points up the need for researchers in knowledge organization to broaden their scope beyond traditional classification systems intended for information retrieval. Argues that work by Beghtol (2003), Kwasnik (1999) and Bailey (1994) offer direction for the development of a classification of classifications based on the pragmatic dimensions of extant classification systems.

- Abstract
- If we are to learn about the impact of computers and networks on society, it will be necessary to address issues from broad cultural-historical perspectives, such as has been done for print culture by those in the 'histoire du livre' tradition. There are paradoxes faced by users of the Internet that have direct implications on their conceptions of the organization of knowledge. Perceptions of knowledge structures may play roles in searching habits or in deciding about he overall appropriateness of a Net search. The Net has been compared to a world brain and is here placed in the context of an early conception of a world brain

- Abstract
- We generally think of conceptual structures (and their mathematical representations: conceptual graphs) as a technical framework providing a sound basis for research and design work in knowledge representation and related areas of computer science. In this article, 1 suggest that conceptual structure predates computer science by some three-million years. In particular, 1 argue that the human brain (or rather, the brain of our hominid ancestors) acquired conceptual structure long before it acquired language, and that the acquisition of conceptual structure was the key cognitive development that led to the emergence of contemporary humans. Moreover, human language was the result of the addition of grammatical structure to an already developed conceptual structure

- Abstract
- Troy State University is a state-affiliated school in southern Alabama with nearly 5.000 mainly undergraduate students. Before 1992, little automation was possible due to budget constraints. Therefore, when money became available in 1992, the librarians sought to bring the state of the art in reference tools - full-text databases - to the students and faculty. The results was the BRAIN (Basic Research and Information Network), a CD-ROM local area network with 4 full-text databases geared for the undergraduate user. After implementation, the BRAIN received an incredible amount of use, and, from anecdotal accounts, the library gained a new respect in the eyes of its users. The palnning process, implementation, full-text databases chosen, and user education, are discussed, as well as the response from users. Undergraduates should be provided access to electronically delivered full-text information

- Abstract
- Human brain size nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age. The timing and reason for this decrease is enigmatic. Here we use change-point analysis to estimate the timing of changes in the rate of hominin brain evolution. We find that hominin brains experienced positive rate changes at 2.1 and 1.5 million years ago, coincident with the early evolution of Homo and technological innovations evident in the archeological record. But we also find that human brain size reduction was surprisingly recent, occurring in the last 3,000 years. Our dating does not support hypotheses concerning brain size reduction as a by-product of body size reduction, a result of a shift to an agricultural diet, or a consequence of self-domestication. We suggest our analysis supports the hypothesis that the recent decrease in brain size may instead result from the externalization of knowledge and advantages of group-level decision-making due in part to the advent of social systems of distributed cognition and the storage and sharing of information. Humans live in social groups in which multiple brains contribute to the emergence of collective intelligence. Although difficult to study in the deep history of Homo, the impacts of group size, social organization, collective intelligence and other potential selective forces on brain evolution can be elucidated using ants as models. The remarkable ecological diversity of ants and their species richness encompasses forms convergent in aspects of human sociality, including large group size, agrarian life histories, division of labor, and collective cognition. Ants provide a wide range of social systems to generate and test hypotheses concerning brain size enlargement or reduction and aid in interpreting patterns of brain evolution identified in humans. Although humans and ants represent very different routes in social and cognitive evolution, the insights ants offer can broadly inform us of the selective forces that influence brain size.
