Chapter 4B Content Review Flashcards
What is the difference between the Surface Web, Deep Web, and Dark Web?
Surface Web: Publicly accessible websites indexed by search engines (e.g., news sites, blogs).
Deep Web: Content not indexed by search engines, requiring login or permission to access (e.g., medical records, academic databases).
Dark Web: A hidden part of the Deep Web that requires special software (e.g., Tor) to access and is often used for anonymity and illegal activities.
How are Wittgenstein’s Forms of Life and Language Games useful in conducting a successful search?
Forms of Life: Different groups use language in specific ways based on their shared experiences.
Language Games: Words have different meanings in different contexts.
Application: Understanding how keywords are used in a specific industry helps refine search queries for better results.
What are the two measures of search success in information retrieval?
Precision: The accuracy of search results (how many retrieved results are relevant).
Recall: The completeness of search results (how many relevant results were retrieved out of all possible relevant results).
What do we mean, in business, by “vertical”?
A vertical refers to a specific industry or market segment.
Examples: Healthcare, retail, finance, real estate.
What is the difference between a general search engine and a vertical search engine?
General Search Engine: Searches the entire web for all types of content.
Examples: Google, Bing, Yahoo.
Vertical Search Engine: Focuses on a specific industry or topic.
Examples: Zillow (real estate), PubMed (medical research), Yelp (local businesses).
When a user conducts a search, what is the user actually doing?
The user is not searching the live web but instead querying the search engine’s indexed database of stored web pages.
How does a search engine populate its database?
A crawler (spider/bot) continuously scans the web, gathering and indexing pages.
The indexed pages are stored in a database, not retrieved directly from the live web when a search is conducted.
How does a search engine work, and what are the roles of the spider/bot, database, and user?
Spider/Bot (Crawler): Automatically scans websites, following links and collecting data.
Database: Stores indexed web pages found by the spider/bot.
User: Enters search queries to retrieve relevant information from the database.
