    Abstract
    This paper is a theoretical analysis of the cognitive free-fall metaphor, used within the cognitive view, as a model for explaining the communication process between a generator and a receiver of a message. Its aim is to demonstrate that the idea of a cognitive free fall taking place within this communication process leads to apparent theoretical paradoxes, partly fostered by unclear definitions of key information-science concepts-namely, tokens, signs, information, and knowledge and their interrelatedness-and a naïve theoretical framework. The paper promotes a semiotically inspired model of communication that demonstrates that what takes place in communication is not a cognitive free fall, but rather a fall from a pragmatic level of knowing or knowledge to a level of representation or information. The paper further argues that the communication process more ideally can be expressed as a complex interrelation of emotion, information, and cognition.

    Abstract
    The organization of information and the process of seeking information are fundamental activities, and thus fields of study, related to library and information science (LIS). Both endeavors are pragmatic in the sense that the ideas of information seeking behavior and the process of organizing information relates to some ideas of how users tend to behave when information is needed in order to fulfill a task of some kind. An important difference is, however, that information systems are primarily driven by principles of semantic structure, whereas users are driven by genuine information needs. Knowledge organization (KO), which is considered a subfield within LIS, has a particular focus on the organization of semantic units, and their relations (Hjørland 2008; Hodge 2000; Thellefsen 2010), however, it is our impression that the users information need, even though acknowledged, often is neglected or only mentioned en passant. The concept of information need is a core concept in LIS, and is, in particular, a core concept within the subfield of information retrieval (IR) that describes the state of uncertainty or anomalous knowledge state that precedes a user's information seeking behavior. Information need is, however, an intricate concept, and is only addressed in the LIS literature as some kind of elusive cognitive state. One may ask 'is an information need always individual or personal, and under what circumstances?' The present paper argues that the concept of information need may profit from a pragmatic and semeiotic perspective, which also may prove fruitful for KO. The paper thus discusses the concept of information need through three premises that is formulated based in Peirce's pragmatic semeiotic: 1) as the intricate relation between believe and doubt, 2) as a pragmatic process of clarification, and 3) as an activity of cognition taking place within a universe of discourse. The paper is rounded by a discussion of how this semeiotic analysis can be useful for KO.

    Abstract
    We present our semeiotic-inspired concept of information as 1 of 3 important elements in meaning creation, the 2 other concepts being emotion and cognition. We have the inner world (emotion); we have the outer world (information); and cognition mediates between the two. We analyze the 3 elements in relation to communication and discuss the semeiotics-inspired communication model, the Dynacom; then, we discuss our semeiotic perspective on the meaning-creation process and communication with regard to a few, but central, elements in library and information science, namely, the systems-oriented perspective, the user-oriented perspective, and a domain-oriented perspective.

    Abstract
    Building on Jens-Erik Mai: 'Semiotics and its uses in library and information science', discusses indexing and semiotics. Presents the concept significance affect as expression of an information effect in index words, based on a discussion of the key concepts in Geroge Lakoff's cognitive semantics: basic-level categorizing, cue validity, prototype effect, kinesthetic image schemas, metaphors, metonymy and radical structures, and idealized cognitive models

    Abstract
    Purpose - The purpose of the paper is to examine and compare Nicholas Belkin's information concept and his concept of communication with the authors' semeiotic inspired communication model - the Dynacom. Design/methodology/approach - The authors compare the two communication models by comparing the requirements given by Belkin and the conditions of the Dynacom. Findings - The authors conclude that Belkin's idea of information and his idea of communication lack the social aspect. Based on his theory, he is unable to point out how information becomes knowledge. These are two major issues the authors believe they can elaborate on by introducing the Dynacom and their semeiotic inspired concept of information. Originality/value - No one has previously specifically analyzed Nicholas Belkin's concept of information and compared it to a semeiotic ditto.
