Main Ideas, Concepts, and Lessons:

  1. Course and Exam Logistics:
    • The lecturer welcomes students and discusses administrative matters regarding slides, assignments, and exams.
    • Updated slides will be sent after modifications; students should discard earlier versions.
    • The exam will be closed-book, focusing on direct questions (multiple-choice and true/false) to test understanding rather than memorization.
    • Students are encouraged to memorize keywords and concepts rather than exact definitions.
    • Assignments will be graded soon, with opportunities for corrections to improve marks.
    • Practice questions and test banks will be provided to help students prepare.
    • Importance of self-training using online resources and test banks is emphasized to familiarize with question formats.
    • Practical parts may be covered briefly if time permits, potentially using Excel.
  2. Introduction to Decision Support Systems and Artificial Intelligence in Information Systems:
  3. Decision-Making Models (Herbert Simon’s Model):
    • Four stages of decision-making:
      1. Intelligence: Identifying the problem.
      2. Design: Developing possible solutions.
      3. Choice: Selecting the best solution after evaluating consequences.
      4. Implementation: Applying the solution and monitoring results.
    • Decision-making is iterative, not strictly linear.
    • Alternative model based on satisficing (accepting a satisfactory solution rather than the optimal one).
  4. Types of Decisions:
    • Structured Decisions: Clear inputs and outputs, governed by fixed rules (e.g., mathematical calculations).
    • Unstructured Decisions: Multiple possible outcomes without clear rules (e.g., business strategy decisions).
    • Recurring Decisions: Regularly repeated decisions (e.g., inventory checks).
    • Non-recurring Decisions: Rare or one-time decisions (e.g., career choices, mergers).
  5. Decision Support Systems (DSS):
    • DSS are flexible systems that interact with IT to support complex decision-making.
    • They handle unstructured data and provide multiple options.
    • Examples include tools like Excel (considered a beginner-friendly DSS).
    • DSS integrates data from multiple sources (internal databases, external government data, personal experience).
    • Components include data management, statistical and analytical tools, and user interfaces.
  6. Geographic Information Systems (GIS):
    • GIS is a type of DSS focused on location-based data.
    • Examples include GPS and Google Earth.
    • Used in business to analyze spatial data such as customer behavior, location analytics, and mapping.
    • GIS integrates databases, query/report tools, multi-dimensional analysis (e.g., OLAP, HyperCube), and dashboards (e.g., Power BI).
  7. Data Mining and Analytical Models:
    • Data mining tools support extracting patterns and knowledge from large datasets.
    • Concepts introduced include:
      • Association (Dependency) Modeling: Finding relationships between variables.
      • Clustering: Grouping data based on similarities.
      • Classification: Assigning data to predefined categories.
      • Regression: Measuring relationships and predicting values.
      • Dispersion: Measuring the spread or closeness of data points.
  8. Predictive Analytics and Text Analytics:
    • Predictive analytics uses historical data and models to forecast future outcomes.
    • Text analytics involves analyzing unstructured text data (e.g., social media posts, reviews) using natural language processing (NLP).
    • NLP tools analyze word frequency, sentiment, and context to interpret human language.
    • Examples of predictive goals: forecasting company profitability, customer behavior, or market trends.
  9. Artificial Intelligence (AI) Systems:
    • AI aims to enable machines to mimic human understanding and reasoning.
    • Key AI systems explained:
      • Expert Systems: Knowledge-based systems that diagnose problems by understanding causes and effects.
      • Neural Networks: Systems that detect patterns in data for classification and prediction.
      • Fuzzy Logic: Deals with uncertainty and partial truths (e.g., weather predictions, traffic signals).
      • Genetic Algorithms: Optimization techniques inspired by natural evolution, adapting solutions to different environments.
      • Agent-Based Technologies:
