    Abstract
    The authors describe a flexible model and a system for content-based image retrieval of objects' shapes. Flexibility is intended as the possibility of customizing the system behavior to the user's needs and perceptions. This is achieved by allowing users to modify the retrieval function. The system implementing this model uses multiple representations to characterize some macroscopic characteristics of the objects shapes. Specifically, the shape indexes describe the global features of the object's contour (represented by the Fourier coefficients), the contour's irregularities (represented by the multifractal spectrum), and the presence of concavities and convexities (represented by the contour scale space distribution). During a query formulation, the user can specify both the preference for the macroscopic shape aspects that he or she considers meaningful for the retrieval, and the desired level of accuracy of the matching, which means that the visual query shape must be considered with a given tolerance in representing the desired shapes. The evaluation experiments showed that this system can be suited to different retrieval behaviors, and that, generally, the combination of the multiple shape representations increases both recall and precision with respect to the application of any single representation.

    Abstract
    An approach to establishing a relationship between knowing, informing and representing, using aspects of linguistic theory to clarify semantic theory as the basis for an overall theory of meaning. Linguistic knowledge is based on a conceptual matrix which defines convergence / divergence of the categories used to specify an object's parameters; work on the analysis of discourse emphasisis the social dimension of meaning, which is the basis of the theory of acts and speech. The evaluation criteria used to determine questions about the possibility of knowledge are necessarily decisive, this opens up promising perspectives if formulating a relationship between conceptual and pragmatic approaches

    Abstract
    Purpose Competitive intelligence failures have devastating effects in marketplaces. They are attributed to various factors but seldom explicitly to information behaviour. This paper addresses causes of competitive intelligence failures from an information behaviour lens focussing on problems with key intelligence and information needs. The exploratory study was conducted in 2016/2017. Managers (end-users) identify key intelligence needs on which information is needed, and often other staff members seek the information (proxy information seeking). The purpose of this paper is to analyse problems related to key intelligence and information needs, and make recommendations to address the problems. Design/methodology/approach The study is placed in a post-positivism research paradigm, using qualitative and limited quantitative research approaches. In total, 15 participants (competitive intelligence professionals and educators/trainers originating from South Africa and the USA) contributed rich data through in-depth individual interviews. Findings Problems associated with articulation of information needs (key intelligence needs is the competitive intelligence term - with a broader scope) include inadequate communication between the person in need of information and the proxy information searcher; awareness and recognition of information needs; difficulty in articulation, incomplete and partial sharing of details of needs. Research limitations/implications Participant recruitment was difficult, representing mostly from South Africa. The findings from this exploratory study can, however, direct further studies with a very understudied group. Practical implications However, revealed valuable findings that can guide research. Originality/value Little has been published on competitive intelligence from an information behaviour perspective. Frameworks guiding the study (a combination of Leckie et al.'s 1996 and Wilson's, 1981 models and a competitive intelligence life cycle), however, revealed valuable findings that can guide research.

    Footnote
    Chapter 2 (Technology and People) focuses an several theories of technological acceptance and diffusion. Unfortunately, Bruce's presentation is somewhat confusing as he moves from one theory to next, never quite connecting them into a logical sequence or coherent whole. Two theories are of particular interest to Bruce: the Theory of Diffusion of Innovations and the Theory of Planned Behavior. The Theory of Diffusion of Innovations is an "information-centric view of technology acceptance" in which technology adopters are placed in the information flows of society from which they learn about innovations and "drive innovation adoption decisions" (p. 20). The Theory of Planned Behavior maintains that the "performance of a behavior is a joint function of intentions and perceived behavioral control" (i.e., how muck control a person thinks they have) (pp. 22-23). Bruce combines these two theories to form the basis for the Technology Acceptance Model. This model posits that "an individual's acceptance of information technology is based an beliefs, attitudes, intentions, and behaviors" (p. 24). In all these theories and models echoes a recurring theme: "individual perceptions of the innovation or technology are critical" in terms of both its characteristics and its use (pp. 24-25). From these, in turn, Bruce derives a predictive theory of the role personal perceptions play in technology adoption: Personal Innovativeness of Information Technology Adoption (PIITA). Personal inventiveness is defined as "the willingness of an individual to try out any new information technology" (p. 26). In general, the PIITA theory predicts that information technology will be adopted by individuals that have a greater exposure to mass media, rely less an the evaluation of information technology by others, exhibit a greater ability to cope with uncertainty and take risks, and requires a less positive perception of an information technology prior to its adoption. Chapter 3 (A Focus an Usings) introduces the User-Centered Paradigm (UCP). The UCP is characteristic of the shift of emphasis from technology to users as the driving force behind technology and research agendas for Internet development [for a dissenting view, see Andrew Dillion's (2003) challenge to the utility of user-centerness for design guidance]. It entails the "broad acceptance of the user-oriented perspective across a range of disciplines and professional fields," such as business, education, cognitive engineering, and information science (p. 34).
    The UCP's effect an business practices is focused mainly in the management and marketing areas. Marketing experienced a shift from "product-oriented operations" with its focus an "selling the products' features" and customer contact only at the point of sale toward more service-Centered business practice ("customer Jemand orientation") and the development of one-to-one customer relationships (pp. 35-36). For management, the adoption of the UCP caused a shift from "mechanistic, bureaucratic, top-down organizational structures" to "flatter, inclusive, and participative" ones (p. 37). In education, practice shifted from the teachercentered model where the "teacher is responsible for and makes all the decisions related to the learning environment" to a learnercentered model where the student is "responsible for his or her own learning" and the teacher focuses an "matching learning events to the individual skills, aptitudes, and interests of the individual learner" (pp. 38-39). Cognitive engineering saw the rise of "user-Centered design" and human factors that were concerned with applying "scientific knowledge of humans to the design of man-machine interface systems" (p. 44). The UCP had a great effect an Information Science in the "design of information systems" (p. 47). Previous to UCP's explicit proposed by Brenda Dervin and M. Nilan in 1986, systems design was dominated by the "physical of system oriented paradigm" (p. 48). The physical paradigm held a positivistic and materialistic view of technology and (passive) human interaction as exemplified by the 1953 Cranfield tests of information retrieval mechanisms. Instead, the UCP focuses an "users rather than systems" by making the perceptions of individual information users the "centerpiece consideration for information service and system design" (pp. 47-48). Bruce briefly touches an the various schools of thought within user-oriented paradigm, such as the cognitive/self studies approach with its emphasis is an an individual's knowledge structures or model of the world [e.g., Belkin (1990)], the cognitve/context studies approach that focuses an "context in explaining variations in information behavior" [e.g., Savolainen (1995) and Dervin's (1999) sensemaking], and the social constructionism/discourse analytic theory with its focus an that language, not mental/knowledge constructs, as the primary shaper of the world as a system of intersubjective meanings [e.g., Talja 1996], (pp. 53-54). Drawing from the rich tradition of user oriented research, Bruce attempts to gain a metatheoretical understanding of the Internet as a phenomena by combining Dervin's (1996) "micromoments of human usings" with the French philosopher Bruno Latour's (1999) "conception of Circulating reference" to form what 1 term the Metatheory of Circulating Usings (pp. ix, 56, 60). According to Bruce, Latour's concept is designed to bridge "the gap between mind and object" by engaging in a "succession of finely grained transformations that construct and transfer truth about the object" through a chain of "microtranslations" from "matter to form," thereby connecting mind and object (p. 56). The connection works as long as the chain remains unbroken. The nature of this chain of "information producing translations" are such that as one moves away from the object, one experiences a "reduction" of the object's "locality, particularity, materiality, multiplicity and continuity," while simultaneously gaining the "amplification" of its "compatibility, standardization, text, calculation, circulation, and relative universality" (p. 57).
    Bruce points out that Dervin is also concerned about how "we look at the world" in terms of "information needs and seeking" (p.60). She maintains that information scientists traditionally view information seeking and needs in terms of "contexts, users, and systems." Dervin questions whether or not, from a user's point of view, these three "points of interest" even exist. Rather it is the "micromoments of human usings" [emphasis original], and the "world viewings, seekings, and valuings" that comprise them that are real (p. 60). Using his metatheory, Bruce represents the Internet, the "object" of study, as a "chain of transformations made up of the micromoments of human usings" (p. 60). The Internet then is a "composite of usings" that, through research and study, is continuously reduced in complexity while its "essence" and "explanation" are amplified (p. 60). Bruce plans to use the Metatheory of Circulating Usings as an analytical "lens" to "tease out a characterization of the micromoments of Internet usings" from previous research an the Internet thereby exposing "the user's view of the Internet" (pp. 60-61). In Chapter 4 (Users of the Internet), Bruce presents the research data for the study. He begins with an explanation of the limits of the data, and to a certain extent, the study itself. The perspective is that of the Internet user, with a focus an use, not nonuse, thereby exluding issues such as the digital divide and universal service. The research is limited to Internet users "in modern economies around the world" (p. 60). The data is a synthesis of research from many disciplines, but mainly from those "associated with the information field" with its traditional focus an users, systems, and context rather than usings (p. 70). Bruce then presents an extensive summary of the research results from a massive literature review of available Internet studies. He examines the research for each study group in order of the amount of data available, starting with the most studied group professional users ("academics, librarians, and teachers") followed by "the younger generation" ("College students, youths, and young adults"), users of e-government information and e-business services, and ending with the general public (the least studied group) (p. 70). Bruce does a masterful job of condensing and summarizing a vast amount of research data in 49 pages. Although there is too muck to recapitulate here, one can get a sense of the results by looking at the areas of data examined for one of the study groups: academic Internet users. There is data an their frequency of use, reasons for nonuse, length of use, specific types of use (e.g., research, teaching, administration), use of discussion lists, use of e-journals, use of Web browsers and search engines, how academics learn to use web tools and services (mainly by self-instruction), factors affecting use, and information seeking habits. Bruce's goal in presenting all this research data is to provide "the foundation for constructs of the Internet that can inform stakeholders who will play a role in determining how the Internet will develop" (p. 129). These constructs are presented in Chapter 5.

    The development of excellent reference skills is an art, and requires skill. Knowledge of how reference works are organised and work is of utmost importance. The librarian is also required to appreciate and understand user needs. It is necesary to solicit the real uestion, which often is not the one asked.

    Abstract
    Explains how the current resurgence of cooperative cataloguing initiatives require that OCLC Online Union Catalog (OLUC) search keys evolve to allow more precise searching. Describes the results achieved by searching personal and corporate authors by word and phrase to obtain guidance on deciding about heading formation and necessary references. Concludes that phrase searching needs to be brought into existence in OLUC search mechanisms as quickly as possible to speed up cataloguing, and that OCLC needs to take note of these requirements by eliminating limitations on searching

    Abstract
    For projects in knowledge-intensive domains, it is crucially important that knowledge management systems are able to track and infer workers' up-to-date information needs so that task-relevant information can be delivered in a timely manner. To put a worker's dynamic information needs into perspective, we propose a topic variation inspection model to facilitate the application of an implicit relevance feedback (IRF) algorithm and collaborative filtering in user modeling. The model analyzes variations in a worker's task-needs for a topic (i.e., personal topic needs) over time, monitors changes in the topics of collaborative actors, and then adjusts the worker's profile accordingly. We conducted a number of experiments to evaluate the efficacy of the model in terms of precision, recall, and F-measure. The results suggest that the proposed collaborative topic variation inspection approach can substantially improve the performance of a basic profiling method adapted from the classical RF algorithm. It can also improve the accuracy of other methods when a worker's information needs are vague or evolving, i.e., when there is a high degree of variation in the worker's topic-needs. Our findings have implications for the design of an effective collaborative information filtering and retrieval model, which is crucial for reusing an organization's knowledge assets effectively.

    Abstract
    Current digital preservation is strongly biased towards data objects: digital files of document-style objects, or encapsulated and largely self-contained objects. To provide authenticity and provenance information, comprehensive metadata models are deployed to document information on an object's context. Yet, we claim that simply documenting an objects context may not be sufficient to ensure proper provenance and to fulfill the stated preservation goals. Specifically in e-Science and business settings, capturing, documenting and preserving entire processes may be necessary to meet the preservation goals. We thus present an approach for capturing, documenting and preserving processes, and means to assess their authenticity upon re-execution. We will discuss options as well as limitations and open challenges to achieve sound preservation, speci?cally within scientific processes.

    Abstract
    The new paradigm of reference, in which the reference librarian becomes a consultant more than a quick-answer specialist, needs to be stretched, Mood advocates. Rather than assisting people with their research, the reference librarian needs to do the research for them. After an interview to assess the user's needs, the librarian searches various print and nonprint access tools, then presents to the patron a bibliography of sources and - possibly - copies of articles and books. This new approach to reference is needed because of both the increasing complication of libraries, with their myriad computer access points to information, and the increasing number of patrons who want information but do not want to learn how to retrieve it. This change in library reference can be implemented with better signage, more prepackaging of information, and an increased knowledge of the local community's information needs
