- Contact information provided.
Unit 1: Background
- Information is different from data and knowledge.
- Data: Raw symbols, facts, and figures that lack meaning.
- Information: Data with meaning; structured, processed data that's useful.
- Knowledge: Evaluated, organized information in human minds enabling purposeful use.
- Information is a vital resource in the information era.
Uses of Information
- Problem-solving, decision-making, reducing uncertainty.
Factors of Good Information
- Relevant, accurate, timely.
Information Explosion and Organization
- The growth of information since the 19th century necessitates its organization.
- Effective organization enables efficient retrieval.
Information Organization and Retrieval
- Core function of information professionals (e.g., librarians, information scientists).
- Often part of the field of library and information science (LIS).
- Information science is the analysis, collection, organization, storage, retrieval, and dissemination of information.
Importance of Information Organization in Libraries
- Enables easier access and retrieval.
- Saves time for library users.
- Maintains order and consistency within the library system.
- Information organisation and retrieval are interdependent tasks.
Information Organization (IO)
- Arranging or sorting information into structure or order (often via filing systems and/or electronic media).
- Activities like document descriptions, indexing, and classification in libraries or other information agencies are considered IO.
Examples of Information Organization
- Cataloguing, subject analysis, indexing, and classification (by humans or computers) in libraries.
- Includes multimedia objects as well as textual documents.
Information Retrieval (IR) as a Field
- The subject is research, teaching, and practice in Library & Information Science (LIS).
- A central discipline, other disciplines (e.g., Computer Science) also apply.
- Sometimes used interchangeably with knowledge organization.
The Concept of Information Retrieval (IR)
- Studies in the 1990s showed that people preferred human interaction for information access (e.g., travel agents).
- Web searches have become the dominant method for information retrieval in recent decades.
- Information retrieval is a long-standing practice that did not arise with the web.
- Development of information retrieval techniques arose in libraries as the number of physical documents expanded.
- "Information retrieval" was coined in 1952.
Meaning of Information Retrieval
- Information retrieval can be a very broad concept encompassing many different actions (e.g., accessing a national ID in a wallet).
- As an academic field, it's the art or science of retrieving information within a specific collection (e.g., library, computer database).
Information Retrieval Systems (IRS)
- IRS are ubiquitous: library catalogues, web search engines.
- World information growth has led to rapid improvements in processing, storage, and retrieval.
- An IRS typically handles textual and possible multimedia documents to serve the user when needed.
Aims of an IRS
- Organising information resources so users access them quickly when requested.
- The system doesn’t offer information content, but merely points user’s toward locations.
Purpose of an IRS
- Store organized information.
- Provide indexes to existing information.
- Retrieve information as per user query.
- Give users documents that meet their needs.
- Optionally, evaluate importance of query results.
