- Abstract
- Natural text phrasing is an indeterminate process and, thus, inherently lacks representational predictability. This holds true in particular in the Gase of general concepts and of their syntactical connectivity. Hence, natural language query phrasing and searching is an unending adventure of trial and error and, in most Gases, has an unsatisfactory outcome with respect to the recall and precision ratlos of the responses. Human indexing is based an knowledgeable document interpretation and aims - among other things - at introducing predictability into the representation of documents. Due to the indeterminacy of natural language text phrasing and image construction, any adequate indexing is also indeterminate in nature and therefore inherently defies any satisfactory algorithmization. But human indexing suffers from a different Set of deficiencies which are absent in the processing of non-interpreted natural language. An optimally effective information System combines both types of language in such a manner that their specific strengths are preserved and their weaknesses are avoided. lf the goal is a large and enduring information system for more than merely known-item searches, the expenditure for an advanced index language and its knowledgeable and careful employment is unavoidable.

- Abstract
- The human's expressing general concepts in uncontrolled natural language, his information need, and meaning recognition in and essence selection from texts are indeterminate processes and therefore defy any satisfactory formalization and programming. Where the equivalence or even superiority of algorithmic approaches to these golas has been claimed, the authors have worked under artificial, experimental conditions and/or have in their evaluation referred to those approaches that are far from exploiting the capabilities of intellectual content analysis, representation and query phrasing

- Abstract
- This article introduces a series of 8 papers giving a survey of the decisions to be made in the choice of the most expedient indexing method and presenting a short description of the contents of each of the papers, namely: the definability of the requested information; individual vs. generic concepts; the predictibility of their mode of expression; the fidelity of concept representation: the indexing language vocabulary; the indexing language grammar; the category-controlled interplay between vocabulary and grammar in an indexing language; the practice of information supply: the personal file; the employment of a large indexing language vocabulary; eth employment of an indexing language syntax

- Abstract
- In ihrer "Mathematical Theory of Communication" beschrieben Shannon und Weaver zur Mitte des vergangenen Jahrhunderts die Technik einer möglichst ungestörten und wirtschaftlichen Nachrichten-Übertragung. Die Einbeziehung der Deutung (Interpretation und Semantik) und der Nutzung der Nachrichten (Pragmatik) blieben der späteren Entwicklung überlassen. Ohne dass es zu dieser Fortentwicklung gekommen wäre, wurde der Geltungsbereich der Theorie jedoch bald auf den gesamten Kommunikationsprozess ausgedehnt. Dies geschah dadurch, dass diese Theorie in "Information Theory" umbenannt wurde, mancherlei Widersprüchen aus der Fachwelt zum Trotz. Noch immer wurde kein Unterschied zwischen Nachricht und Information gemacht, und einer jeglichen Nachricht und jeglichem Signal wurde eine neu definierte Art von "Informationsmenge" zugewiesen. Dieser rein statistische Begriff ist weit entfernt von der ureigentlichen Bedeutung des Wortes "Information". Was eine Nachricht bedeutet und ob sie für den Empfänger verständlich, interessant und nützlich ist, bleibt in dieser Theorie außer Betracht. Die Ursachen, der Verlauf und die Folgen dieser Verirrung werden untersucht und kritisiert. Wenn und so lange auch die Informatik einen solchen "Informations"-Begriff zu ihrer Grundlage hat, entbehrt sie jeglicher Kompetenz auf dem Gebiet dessen, was traditionell und umgangsprachig unter Information verstanden wird. Durch die ungerechtfertigte Beanspruchung und Durchsetzung von Zuständigkeit für das Gesamtgebiet der Information hat die "Informations"-Theorie weitverbreitet großen Schaden verursacht. Dies gilt bei aller Anerkennung der großen Fortschritte in der Informatik bei der reinen Technik der Datenverarbeitung, die aufgrund dieser Theorie ebenfalls erzielt worden sind. Teil 1 behandelt die index-relevanten Aspekte der "Informationstheorie".
