Searching for Information

  • Web and Internet

    • Distinction between the Web and Internet: They are not the same.

    • Students are encouraged to understand how to access the World Wide Web using web browsers like Chrome, Safari, Brave, etc.

  • Search Engine Basics

    • A search engine is a program that queries databases for specific information.

    • Common search engines include Google, Bing, and Yahoo.

    • Understanding how search engines work is critical for effective information retrieval.

  • Types of Webs

    • Surface Web: Contains only about 1-5% of all web pages, accessible via search engines.

    • Deep Web: Consists of web pages not indexed by search engines, often requiring logins or found behind paywalls (e.g., institutional pages).

    • Dark Web: Not indexed and requires specific browsers (e.g., Tor) for access; associated with both legal and illicit activities.

Types of Search Engines

  • General Purpose Search Engines

    • Examples: Google, Bing, Yahoo – cover a broad range of topics without restriction.

  • Vertical Search Engines

    • Tailored for specific topics (e.g., Etsy for crafts, Indeed for job searches).

  • Meta Search Engines

    • Utilize other search engines to return consolidated results (e.g., Kayak for travel).

  • AI Search Engines

    • Utilize AI technology to enhance search capabilities, moving towards understanding user intent rather than simple keyword matching.

  • Concept of SEO

    • Focus on optimizing web pages to rank highly within search results based on specific keywords.

    • Understanding the dynamics of how search rankings work in relation to their advertising system.

    • AI-enabled platforms focus more on understanding query intent and summarizing information.

Importance of Search Engine Use

  • Precision and Recall

    • Recall: This measures the total amount of relevant documents found.

    • A balance of both is essential to optimize the search for quality information.

The Role of Language in Search

  • Language Games

    • The concept by Ludwig von Wittgenstein describes how language varies based on context and audience.

    • Understanding the language and jargon of different fields is important for effective communication and information retrieval.

  • Context Matters

    • Language nuances affect how information is conveyed and understood across different professions.

Practical Application in the Course

  • Exercise on Search Queries

    • Students are tasked with indexing information by generating diverse descriptions that could enhance search visibility (SEO).

    • Emphasis on utilizing advanced search techniques to narrow results and target specific information needs.

  • Exists Across All Functions

    • The principles discussed will apply across various domains, from marketing to technical research.

    • Understanding these concepts is essential for students' careers and engagements with digital information.
