Modeling Computing and Journalism (Part I)

Recently I’ve been thinking more about modeling the intersection of computing and journalism, and in particular thinking about ways that aspects of computing might impact or allow for innovation in journalism. It struck me that I needed a more precise definition of computing and its purview (I’ll come back to the journalism side of the equation in a later post). What, exactly, is computing? I’ll try to answer that in this post…

Definitions of computing and computer science abound online, but the most canonical comes perhaps from Peter Denning, an elder in the field of Computer Science. In a CACM article from 2005 he writes, “Computing is the systematic study of algorithmic processes that describe and transform information”. Two key words there: “algorithmic” and “information”. Computing is about information, about describing and transforming it, but also about acquiring, representing, structuring, storing, accessing, managing, processing, manipulating, communicating, and presenting it. And computing is about algorithms: their theory, feasibility, analysis, structure, expression, and implementation. The fundamental question of computing concerns what information processes can be effectively automated.

In modern CS there is a huge body of knowledge that stems from this core notion of computing. For instance, the Computer Science Curriculum defined in 2008 defines 14 different areas of knowledge (see list below). The Georgia Tech College of Computing delineates some of these areas as belonging to core computer science, and others belonging to interactive computing. Roughly, core computer science deals with the conceptual (i.e. mathematical), and operational (i.e nuts and bolts of how a modern computer works) aspects of computing. Interactive computing on the other hand mostly deals with information input, modeling, and output. There are aspects of professional practice, engineering, and design that apply in both.

Core Computer Science

  • Discrete Structures, Programming Fundamentals, Software Engineering, Algorithms and Complexity, Architecture and Organization, Operating Systems, Programming Languages, Net Centric Computing, Information Management, Computational Science

Interactive Computing

  • Human Computer Interaction, Graphics and Visual Computing, Intelligent Systems

In terms of modeling the intersection of computing and journalism it’s the interactive side of things that’s most interesting. How information is moved around inside a computer is less important for journalists to understand than the interactive capabilities of information input, modeling, and output afforded by computing.  That is, how does computing interface with the rest of the world? Of course many of the capabilities of computers studied in interactive computing rest on solid foundations of core computer science (e.g. you couldn’t get much done without an operating system to schedule processes and manage data). Core areas with particular relevance to interactive computing are technologies in networking/communications, information management, and to a lesser extent computational science. Below I list more detailed sub-areas for each of the interactive computing and related core areas.

  • Human Computer Interaction (HCI) includes sub-areas such as interaction design, user-centered design, multimedia systems, collaboration, online communities, human-robot interaction, natural interaction, tangible interaction, mobile and ubiquitous computing, wearable computing, and information visualization
  • Graphics and Visual Computing includes sub-areas such as geometric modeling, materials modeling and simulation, rendering, image synthesis, non-photorealistic rendering, volumetric rendering, animation, motion capture, scientific visualization, virtual environments, computer vision, image processing and editing, game engines, and computational photography
  • Intelligent Systems includes sub-areas such as general AI including search and planning, cognitive science, knowledge-based reasoning, agents, autonomous robotics, computational perception, machine learning, natural language processing and understanding, machine translation, speech recognition, and activity recognition
  • Net Centric Computing includes aspects of networking, web architecture, compression, and mobile computing.
  • Information Management includes aspects of database systems, information architecture, query languages, distributed data, data mining, information storage and retrieval, hypermedia, and multimedia databases.
  • Computational Science includes aspects of modeling, simulation, optimization, and parallel computing often oriented towards big data sets.

So what can we do with this detailed typology of interactive computing technology?

In a 2004 CACM article Paul Rosenbloom developed a notation for describing how computing interacts with other fields. In his typology, he articulated ways in which computing could implement, interact with, and embed with other disciplines, namely with physical, life, and social sciences. These different relationships between fields lead to different kinds of ideas for technology (e.g. an embedding relationship of computing in life sciences would be the notion of cyborgs, an interaction between computing and physical sciences would be robotics). In this spirit, later on in this blog series I’ll look more specifically at how some of the computing technologies articulated above can map to aspects of journalism practice, with an eye toward innovation in journalism by applying computing in new or under-explored ways.
