- "Bitte suchen Sie alle Unterlagen, die im PC zum Ibelshäuser-Vertrag in Sprockhövel gespeichert sind. Finden Sie alles, was wir haben - Dokumente, Tabellen, Präsentationen, Scans, E-Mails. Und erledigen Sie das gleich! « Wer diese Aufgabe an das Windows-eigene Suchmodul vergibt, wird zwangsläufig enttäuscht. Denn das Betriebssystem beherrscht weder die formatübergreifende Recherche noch die Kontextsuche, die für solche komplexen Aufträge nötig sind. Professionelle Desktop-Suchmaschinen erledigen Aufgaben dieser Art jedoch im Handumdrehen - genauer gesagt in einer einzigen Sekunde. Spitzenprogramme wie Global Brain benötigen dafür nicht einmal umfangreiche Abfrageformulare. Es genügt, einen Satz im Eingabefeld zu formulieren, der das Thema der gewünschten Dokumente eingrenzt. Dabei suchen die Programme über alle Laufwerke, die sich auf dem System einbinden lassen - also auch im Netzwerk-Ordner (Shared Folder), sofern dieser freigegeben wurde. Allen Testkandidaten - mit Ausnahme von Search 32 - gemeinsam ist, dass sie weitaus bessere Rechercheergebnisse abliefern als Windows, deutlich schneller arbeiten und meist auch in den Online-Postfächern stöbern. Wer schon öfter vergeblich über die Windows-Suche nach wichtigen Dokumenten gefahndet hat, kommt angesichts der Qualität der Search-Engines kaum mehr um die Anschaffung eines Desktop-Suchtools herum. Aber Microsoft will nachbessern. Für den Windows-XP-Nachfolger Longhorn wirbt der Hersteller vor allem mit dem Hinweis auf das neue Dateisystem WinFS, das sämtliche Files auf der Festplatte über Meta-Tags indiziert und dem Anwender damit lange Suchläufe erspart. So sollen sich anders als bei Windows XP alle Dateien zu bestimmten Themen in wenigen Sekunden auflisten lassen - unabhängig vom Format und vom physikalischen Speicherort der Files. Für die Recherche selbst ist dann weder der Dateiname noch das Erstelldatum ausschlaggebend. Anhand der kontextsensitiven Suche von WinFS kann der Anwender einfach einen Suchbefehl wie »Vertragsabschluss mit Firma XYZ, Neunkirchen/Saar« eingeben, der dann ohne Umwege zum Ziel führt."

- 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
- A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

- 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
- Let us say that anything we can talk about is an entity, anything we can truly say about an entity is a quiddity (Latin quid "what"). Each quiddity is in turn an entity. So objects, concepts and names (terms) are entities and have quiddities. The properties (quiddities) of objects are represented by characteristics (quiddities) of concepts, and these quiddities are concepts themselves. There are simple concepts and complex sets of concepts. Entities and quiddities can be r e.g.arded differently in different languages and disciplines; their ontological cat e.g.orization depends on the respective epistemological point of view. Material objects usually represent themselves, names usually represent something else (objects via concepts), but both are part of the world outside the brain, where only individuals exist. However, names can also represent themselves and then . their quiddities refer to their appearance (e.g. black letters) or function (e.g. noun), etc. Immaterial objects as "preconceptual" entities and concepts exist only within the brain. A concept, general or individual, is composed of a name concept and an object concept, which although stored in different parts of the brain (brain research) usually remain in contact with each other.

- 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 success of the World Wide Web Shows that we can access, search, and retrieve information from globally distributed databases. lf a database, such as a library catalog, has some sort of Web-based front end, we can type its URL into a Web browser and use its HTML-based forms to search for items in that database. Depending an how well the query conforms to the database content, how the search engine interprets the query, and how the server formats the results into HTML, we might actually find something usable. While the first two issues depend an ourselves and the server, an the Web the latter falls to the mercy of HTML, which we all know as a great destroyer of information because it codes for display but not for content description. When looking at an HTML-formatted display, we must depend an our own interpretation to recognize such entities as author names, titles, and subject identifiers. The Web browser can do nothing but display the information. lf we want some other view of the result, such as sorting the records by date (provided it offers such an option to begin with), the server must do it. This makes poor use of the computing power we have at the desktop (or even laptop), which, unless it involves retrieving more records, could easily do the result Set manipulation that we currently send back to the server. Despite having personal computers wich immense computational power, as far as information retrieval goes, we still essentially use them as dumb terminals.

- 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.
