Information Technology Concerned with 4 processes: Information creation or capture Information transmission Information storage How badly we want the information to be retrievable How the information was initially packaged Management and control of information flow and creation of systems to accomplish this task 2  23/07/2024 What else about Informatics? The term has increasingly Was regarded as the been used to describe applied use of the application of information science. information technology to other fields. ▪ It’s more than computer science or information science Has been emerging as an because it includes all interdisciplinary field that is concerned with the study aspects of the computer of the nature of information milieu and human & technology behavior. What is Information Science? Some background: Emerged around 1958 with the Institute of Information Scientists (IIS) Various attempts to merge with other disciplines for a stronger scientific position such as : A move toward communication A merger with computer science 3  23/07/2024 What is Information Science? Information Science is a field of professional practice and scientific inquiry addressing the effective communication of information and information objects, particularly knowledge records, among humans in the context of social, organizational, and individual needs for and use of information. What is Information Science? Two key Orientation: 1. Toward the human and social need for and use of the information pertaining to knowledge records (human information behavior). 2. Toward specific information techniques, systems, and technologies (covered under the name of information retrieval) to satisfy that need and provide for effective organization and retrieval of information. 4  23/07/2024 What is Information Science? Made up of 2 components: (practical) the study of gathering, organizing, storing, retrieving, & dissemination of information (theoretical) as a meta-field that analyzes the processes and domains of information Information Science Attributes To be concerned with the form, organization, & structure of information, only secondarily with the content To acknowledge the representation of information by indexing, or querying what a user needs is DIFFERENT from knowing the information Subject expertise a bonus, but unnecessary The information perspective is the ability to see the world at both the theoretical and practical levels 5  23/07/2024 What is Information Theory? Many, many views expressed in the readings but all have a common thread that information scientists are interested in the structure of information. Information Science is interested in information as a social and psychological phenomenon with a primary focus on recorded information and people’s relationship to it. 3 Big Questions of Information Science 1. The physical question: What are the features and laws of the recorded information universe 2. The social question: How do people relate to, seek, and use information? 3. The design question: How can access to recorded information be made the most rapid and effective? 6  23/07/2024 What is Information Science? Problem Addressed by IS: 1. Generally, information science addressed the problem of information explosion and used information technology as a solution. ▪ The rapid pace of scientific and technical advances that were accumulating since the start of the 20th century produced mid-century a scientific and technical revolution. ▪ The unabated, exponential growth of scientific and technical publications and information records of all kinds. ▪ Simply put, an information explosion is information and information objects piling up at a high rate. 2. The problem this presents is getting the right information as needed at any given time.
