Abstract

Information science has been convincingly characterised as a response to developments in information and communications technologies and as part of the gestalt of the computer. Despite this, it has had a limited understanding of information technology and has repressed or disguised its origins. Its understanding of itself and its potential for contribution to other discourses has thereby been restricted. The paper develops an understanding of information technology. The idea that the computer as a machine is concerned with the transformation of information, not material or energy, is extended to other information technologies. Technology is regarded as a radical human construction, in a position derived from Marx and mediated by economics. On these bases, an understanding of information technology as a form of knowledge concerned with the transformation of signals from one form or medium into another is proposed. Invention, innovation, and diffusion are distinguished as stages in the development of technologies. For modern information technologies, the history of copyright can provide indicators for innovation and diffusion. The mid- to late 19th century, in the United States and between the United States and Europe, is identified as the critical period for diffusion. An explanation for this is proposed in terms of the dynamism of the period, its hospitality to innovation, and in the United States continental expansion and developing links with Europe.

Abstract

This article synthesizes the labor theoretic approach to information retrieval. Selection power is taken as the fundamental value for information retrieval and is regarded as produced by selection labor. Selection power remains relatively constant while selection labor modulates across oral, written, and computational modes. A dynamic, stemming principally from the costs of direct human mental labor and effectively compelling the transfer of aspects of human labor to computational technology, is identified. The decision practices of major information system producers are shown to conform with the motivating forces identified in the dynamic. An enhancement of human capacities, from the increased scope of description processes, is revealed. Decision variation and decision considerations are identified. The value of the labor theoretic approach is considered in relation to preexisting theories, real-world practice, and future possibilities. Finally, the continuing intractability of information retrieval is suggested.

Abstract

This paper considers an instance of non-verbal graphic communication from the legend of Theseus, in terms of information theory. The efficient cause of a failure in communication is regarded as a selection error and the formal cause as the absence of redundancy from the signals (a binary contrast between a black and a white sail) for transmission. Two considerations are then introduced. First, why should such a system of signalling have been succeeded by a graphic communication system, in alphabetic written language, so strongly marked by its redundancy? Second, why has information theory been so successful in describing systems for signal transmission but far less productive for modelling human-to-human communication, at the level of meaning or of the effects of messages on recipients? The legend is read historically, adopting specific insights, a method of interpretation, and a historical schema from Vico. The binary code used for the signal transmission is located as a rare but significant transitional form, mediating between heroic emblems and written language. For alphabetic written language, a link to the sounds of oral utterance replaces the connection to the mental states of the human information source and destination. It is also suggested that redundancy was deliberately introduced to counteract the effects of selection errors and noise. With regard to information theory, it is suggested that conformity with necessary conditions for signal transmission, which may include the introduction of redundancy, cannot be expected to yield insights into communication, at the level of meaning or the effects of messages.

Abstract

The distinction between a meta- and an object-language has become increasingly familiar in information science, through the diffusion of the concept of metadata. A significant antecedent to this distinction can be found in the development of formal logic. This paper proposes an analogous distinction for information retrieval research, between the metalanguage of discourse about information retrieval systems and the object-language of transformations within systems. In formal logic, acceptance of a meta:object distinction has had a clarifying and simplifying effect. An understanding of potential object-language transformations as the writing, erasure, and substitution of symbols has also been developed. The existing metalanguage of information retrieval research has displayed a founding assumption (the value of delivering all, and possibly only all, the records relevant to a given query), some central concepts, entities for evaluative purposes, and derived measures. An alternative founding principle of enhanced informed choice is endorsed. The emerging view of operations within information retrieval systems such as transformation, sorting, and partitioning is strongly analogous to the more fully established account of possible object-language transformations in formal logic. Analytical clarity has been obtained and economy in research effort is made possible.

Abstract

An analogy is established between the syntagm and paradigm from Saussurean linguistics and the message and messages for selection from the information theory initiated by Claude Shannon. The analogy is pursued both as an end in itself and for its analytic value in understanding patterns of retrieval from full-text systems. The multivalency of individual words when isolated from their syntagm is contrasted with the relative stability of meaning of multiword sequences, when searching ordinary written discourse. The syntagm is understood as the linear sequence of oral and written language. Saussure's understanding of the word, as a unit that compels recognition by the mind, is endorsed, although not regarded as final. The lesser multivalency of multiword sequences is understood as the greater determination of signification by the extended syntagm. The paradigm is primarily understood as the network of associations a word acquires when considered apart from the syntagm. The restriction of information theory to expression or signals, and its focus on the combinatorial aspects of the message, is sustained. The message in the model of communication in information theory can include sequences of written language. Shannon's understanding of the written word, as a cohesive group of letters, with strong internal statistical influences, is added to the Saussurean conception. Sequences of more than one word are regarded as weakly correlated concatenations of cohesive units.

Abstract

This study examines the relation between selection power and selection labor for information retrieval (IR). It is the first part of the development of a labor theoretic approach to IR. Existing models for evaluation of IR systems are reviewed and the distinction of operational from experimental systems partly dissolved. The often covert, but powerful, influence from technology on practice and theory is rendered explicit. Selection power is understood as the human ability to make informed choices between objects or representations of objects and is adopted as the primary value for IR. Selection power is conceived as a property of human consciousness, which can be assisted or frustrated by system design. The concept of selection power is further elucidated, and its value supported, by an example of the discrimination enabled by index descriptions, the discovery of analogous concepts in partly independent scholarly and wider public discourses, and its embodiment in the design and use of systems. Selection power is regarded as produced by selection labor, with the nature of that labor changing with different historical conditions and concurrent information technologies. Selection labor can itself be decomposed into description and search labor. Selection labor and its decomposition into description and search labor will be treated in a subsequent article, in a further development of a labor theoretic approach to information retrieval.

Abstract

The analytic advantages of central concepts from linguistics and information theory, and the analogies demonstrated between them, for understanding patterns of retrieval from full-text indexes to documents are developed. The interaction between the syntagm and the paradigm in computational operations on written language in indexing, searching, and retrieval is used to account for transformations of the signified or meaning between documents and their representation and between queries and documents retrieved. Characteristics of the message, and messages for selection for written language, are brought to explain the relative frequency of occurrence of words and multiple word sequences in documents. The examples given in the companion article are revisited and a fuller example introduced. The signified of the sequence stood for, the term classically used in the definitions of the sign, as something standing for something else, can itself change rapidly according to its syntagm. A greater than ordinary discourse understanding of patterns in retrieval is obtained.

Abstract

The contrast between the value placed on discriminatory power in discussions of indexing and classification and on the transformation of a query into a set of relevant records dominant in information retrieval research has not yet been fully explored. The value of delivering relevant records in response to a query has been assumed by information retrieval research paradigms otherwise differentiated (the cognitive and the physical). Subsidiary concepts and measures (relevance and precision and recall) have been increasingly subjected to critiques. The founding assumption of the value of delivering relevant records now needs to be questioned. An enhanced capacity for informed choice is advocated as an alternative principle for system evaluation and design. This broadly corresponds to: the exploratory capability discussed in recent information retrieval research; the value of discriminatory power in classification and indexing; Giambattista Vico's critique of the unproductivity of Aristotelian methods of categorisation as routes to new knowledge; and, most significantly, to ordinary discourse conceptions of the value of information retrieval systems. The criterion of enhanced choice has a liberating effect, restoring man as an artificer and enabling a continuing dialectic between theory and practice. Techniques developed in classic information retrieval research can be adapted to the new purpose. Finally, the substitution of the principle of enhanced choice exemplifies the development of a true science, in which previous paradigms are absorbed into new as special cases.

Abstract

Selection power is taken as the fundamental value for information retrieval systems. Selection power is regarded as produced by selection labor, which itself separates historically into description and search labor. As forms of mental labor, description and search labor participate in the conditions for labor and for mental labor. Concepts and distinctions applicable to physical and mental labor are indicated, including the necessity of labor for survival, the idea of technology as a human construction, and the possibility of the transfer of human labor to technology. Distinctions specific to mental labor, particularly between semantic and syntactic labor, are introduced. Description labor is exemplified by cataloging, classification, and database description, can be more formally understood as the labor involved in the transformation of objects for description into searchable descriptions, and is also understood to include interpretation. The costs of description labor are discussed. Search labor is conceived as the labor expended in searching systems. For both description and search labor, there has been a progressive reduction in direct human labor, with its syntactic aspects transferred to technology, effectively compelled by the high relative costs of direct human labor compared to machine processes.

Abstract

This paper reviews developments from a study of the reception of the Research Assessment Exercise 1996. Research evaluation, including the value of citation analysis and the responsibilities attaching to publication of citation analyses, is considered. The distinctions made in the communication model for analysing reception, between dissemination and diffusion and between esoteric and exoteric media and communities, are developed further. Information transfer is represented as an explicable process. Possible further developments, including the appropriate relation to disciplines with related interests in the social communication of knowledge, are anticipated.
