23. 1:53Slide 4 – Search Engines are Digital Tools!
24. 2:01Introduce search engines as digital tools.
25. 2:06Search engines are so obvious and ingrained in our daily life that we don’t even think
26. 2:33about them as being digital tools.
27. 2:41Slide 5 – What is a Search Engine?
28. 2:50A search engine is a digital software or tool that is designed to work with the internet
29. 2:56to search for information based on the input provided.
30. 3:01Input can be keywords, images, phrases, questions, etc.
31. 3:08A search engine is not the same as a browser.
32. 3:13A browser is your access to the internet, and a search engine allows you to search the
33. 3:19internet once you have access.
34. 3:22You have to use a browser to get to a search engine.
35. 3:27Recall the mind map…digital tools are interconnected.
36. 3:35Hardware is the necessary foundation and software is the programming.
37. 3:42Slide 6 – How do Search Engines Work?
38. 4:12Crawl and index all the data on the web so that when you search for something, it can
39. 4:16present you with a set of results, ranked by relevance.
40. 4:21Crawl: Web crawlers, also known as spiders or spiderbots, are programs that constantly
41. 4:31search the internet, finding new sites and identifying new links.
42. 4:37These small bots can scan all sections and subpages of a website, including content such
43. 4:44as video and images.
44. 4:47Crawlers also send text from every website to an index to be analyzed.
45. 4:54Crawlers may even store all or part of a web page, called a cache.
46. 4:59Webmasters (the people who run websites) can add a file called robots.txt to their sites,
47. 5:08which tells a crawler which pages to look at or ignore.
48. 5:17Index: The data that crawlers gather is analyzed, organized, and stored in an index so that
49. 5:29the engine can find information quickly.
50. 5:33Like the index found in the back of a book—but far more detailed—a search engine index
51. 5:40includes an entry for every word on every indexed web page.
52. 5:45Once all data has been fetched by the bots, the crawler adds it to a massive online library
53. 5:53of all discovered URLs.
54. 5:56This constant and recursive process is known as indexing.
55. 6:03Search: When you query a search engine, the search engine must first translate your words
56. 6:12into terms that relate to its index.
57. 6:16This is done via a host of techniques including natural language processing (NLP which uses
58. 6:24machine learning to understand what you’re looking for).
59. 6:28The output of this initial translation process is a rewritten query that identifies the important
60. 6:36parts of your query, corrects misspellings, and adds on synonyms.
61. 6:43The search engine then consults its index to find web pages that match the rewritten
62. 6:49query.
63. 6:52Rank: Search engines use algorithms to present you with a list of results prioritized by
64. 7:02what it thinks will best answer your query.
65. 7:07For vague searches, like “ramen,” your search engine may provide a range of answers
66. 7:18to cover its bases, such as general information about what ramen is, along with other popular
67. 7:25results like recipes, local ramen shops, and even a “people also ask” section to help
68. 7:33you narrow down your search.
69. 7:36Search engines examine the keywords in the query to match some or all of them, analyze
70. 7:43backlinks which are the times the site is mentioned in or linked to other sites, and
71. 7:50user information which is personal search history and location information to prioritize
72. 7:57what it thinks you are looking for.
73. 8:02Since most users only browse the top results, it is particularly important for a website
74. 8:10to rank high enough for certain queries to ensure its success in terms of traffic.
75. 8:18A whole science developed in the last few decades to make sure that a website, or at
76. 8:25least some of its pages, “scale” the ranking to reach the first positions.
77. 8:30This discipline is known as Search Engine Optimization (SEO).
78. 8:37Each search engine now uses its proprietary algorithm that weighs many complex factors
79. 8:46such as relevancy, accessibility, usability, page speed, content quality, and user intent
80. 8:56in order to sort the pages in a certain order.
81. 9:02Slide 7 – Types of Search Engines Remind students that being digitally fluent
82. 9:16means knowing the functions of different search engines so that they can make educated choices.
83. 9:22Mainstream search engines.
84. 9:26Mainstream search engines like Google, Bing, and Yahoo! are all free to use and supported
85. 9:34by online advertising.
86. 9:37They all use variations of the same strategy (crawling, indexing, and ranking) to let you
87. 9:44search the entirety of the internet.
88. 9:49Private search engines.
89. 10:00Private search engines have risen in popularity recently due to privacy concerns raised by
90. 10:24the data collection practices of mainstream search engines.
91. 10:30These include anonymous, ad-supported search engines like DuckDuckGo and private, ad-free
92. 10:39search engines like Neeva.
93. 10:43Computational search engines.
94. 10:44WolframAlpha is an example of a computational search engine, devoted to answering questions
95. 10:54related to math and science.
96. 10:58Vertical search engines.
97. 11:00Vertical search, or specialized search, is a way of narrowing your search to one topic
98. 11:09category, rather than the entirety of the web.
99. 11:15Examples of vertical search engines include the search bar on shopping sites like eBay
100. 11:25and Amazon; Google Scholar, which indexes scholarly literature across publications;
101. 11:35and searchable social media sites and apps like Pinterest.
102. 11:56Slide 8 – Which Search Engine Should I Use?
103. 12:13Web page search engine: Often multi-purposed, they locate all sorts of data, from general
104. 12:23web pages and news to help documents, online games, and usually more like images, videos,
105. 12:35and files.
106. 12:38Image search engines: Search for photos, drawings, clip art, wallpapers, etc.
107. 12:55Video search engines: Find music videos, news videos, live streams, and more.
108. 13:09(YouTube) People search engines: Locate people on the
109. 13:16internet using their name, address, phone number, email address, etc.
110. 13:19Mobile search engines: A regular search engine that's optimized for searching and displaying
111. 13:28results on a smaller screen.
112. 13:31Job search engines: Find job postings.
113. 13:34Library search engines: UAGC Library Slide 9 – Most Widely Used Search Engines
114. 13:43As of 2020, Google controls the vast majority of the western market; Microsoft Bing has
115. 13:48a small presence in second place.
116. 13:52While Yahoo generates many queries, their back-end search technology is outsourced to
117. 13:59Microsoft.
118. 14:00In other regions of the world, other search engines hold the majority of the market.
119. 14:06In China, for example, the most widely used search engine is Baidu, which was originally
120. 14:15launched in 2000, while in Russia more than 50% of users use Yandex.
121. 14:21Slide 10 – Alphabetical List of Search Engines Review a few of them.
122. 14:29Slide 11 - Alphabetical List of Search Engines Review a few of them
123. 14:36Slide 12 – Digital Fluency and Search Engines
124. 14:45Note the five stars on the slide and be sure to call them out.
125. 15:00Technical Proficiency: Knowing how search engines function (e.g. crawling, indexing,
126. 15:12searching, ranking) Digital Literacy: Understanding how to use
127. 15:22search engines safely (e.g. privacy and security) and critically
128. 15:31Social Competence: Understanding how search engines could be programmed to produce results
129. 15:47that include controversial, sensationalized, or dangerous topics
130. 15:52When it came to controversial (anything considered to be divisive such as Covid 19 vaccine, 2020
131. 16:08election, etc.): • 27% of DuckDuckGo results were classified
132. 16:19as misinformation or sensationalism. • 25% of Bing results were classified as
133. 16:38misinformation or sensationalism. • 18% of Yahoo results were classified as
134. 17:07misinformation or sensationalism. • 2% of
135. 17:24Google results were classified as misinformation or sensationalism
136. 17:29Regarding dangerous intent (Anything that leads to a dangerous situation such as how
137. 17:38to print a 3-D gun or make pressure cooker bombs, the
138. 18:18search
139. 18:32engines ranked as follows: Most likely: DuckDuckGo
140. 18:43Likely: Bing Less likely: Yahoo
141. 18:53Not likely: Google
142. 19:02What conclusions would you draw from this?
143. 19:18Consider the algorithms that drive the results.
144. 19:45Slide 13 Safe searching
145. 20:02Ask students to put in chat some suggestions as to
146. 20:40how to surf the net safely.
147. 23:02Can include: Avoid sites that are clearly biased
148. 24:38Do research about the algorithms used by a specific search engine
149. 24:48Update/upgrade security settings Use antivirus protection and firewall
150. 25:01Create clear and targeted search criteria Suggest that students experiment with 3-4
151. 25:12different search engines and compare the results.
152. 25:23Slide 14 Q/A
153. 25:29About search engines, questions in general, etc.
