What This Document Is
This document contains lecture materials from INFO 202, Information Organization and Retrieval, at UC Berkeley. Specifically, these are the session materials for a lecture focused on the principles and practices of classification – a fundamental concept in information science. It delves into the theoretical underpinnings of how we categorize information and build systems for organizing knowledge. The materials explore the distinctions between simple categorization and more formal classification systems.
Why This Document Matters
Students enrolled in INFO 202, or those with an interest in information architecture, library science, data management, or knowledge organization will find these materials valuable. It’s particularly useful for understanding the core concepts discussed in an introductory information science course. Reviewing these materials can help solidify understanding of how information systems are structured and how effective organization impacts retrieval and usability. It’s ideal for supplementing lecture notes and preparing for related coursework.
Topics Covered
* The fundamental definition and purpose of classification
* Distinguishing between categorization and classification as distinct processes
* The core functions of classification systems in various contexts
* Principles governing the structure and design of classification systems
* The concept of “principled” classification – lawful, systematic, and arbitrary approaches
* Hierarchy and uniqueness principles in classification design
* Guidance on applying classification rules and resolving ambiguities
* Overview of established classification systems
What This Document Provides
* A detailed exploration of the theoretical foundations of classification.
