    Slide 1:Web Searching Strategies

    Independent Investigations for Grades 9-12, Teacher Training, and Staff Development

    Slide 2:Web Searching Strategies

    The Web is huge Search engines make finding information much easier when used effectively Search directories are a good alternative to search engines when your topic is very general Don’t forget to properly cite information found Make searching safe for students Understand and teach your students how to evaluate Web sites

    Slide 3:Search Engines

    Slide 4:How Search Engines Work

    Search Engines are huge, searchable databases of Web sites They search the Internet -- or select pieces of the Internet -- based on important words. They keep an index of the words (keywords) they find, and where they find them. They allow users to look for words or combinations of words found in that index. “Keyword” A word that is entered into the search form or search "window" of an Internet search engine to search the Web for pages or sites about or including the word and information related to it.

    Slide 5:How Search Engines Work

    What are robots, spiders, and crawlers? Computer programs the automatically gather information Spiders look at sites submitted to search engines Crawlers are programmed to constantly search the web, following any and all links they come across Spiders (http://computer.howstuffworks.com/search-engine1.htm) Search Engines are huge, searchable databases of Web sites. What are Robots, Spiders, and Crawlers? To create these databases, programmers write computer programs to automatically gather information. These are called robots or spiders. Essentially, a robot is a software program that "crawls" through the Web on a regular basis, searching and indexing text ( “keywords”) from Web pages to create a database that can be easily searched by a search engine. A “keyword” is a word that is entered into the search form or search "window" of an Internet search engine to search the Web for pages or sites about or including the word and information related to it. Different sites use different programs and therefore their databases will be different. http://computer.howstuffworks.com/search-engine1.htm Spiders, one type of robot, look at sites that are submitted to search engines Crawlers, another type, are like spiders, except they are programmed to constantly surf the web, following any and all links they come across.

    Slide 6:How Search Engines Work

    How do search engines display results? A list of document titles with links to the Web site containing your keyword(s) The number of files located that contain your keyword(s) A brief description of your keyword(s) How do search engines display results? Most search engines will display A list of document titles with links to the Web site containing your keyword(s) The number of files located that contain your keyword(s) A brief description of your keyword(s) Most search engines will display the results in a ranked order based on their own unique weighting systemsHow do search engines display results?

    Do different search engines produce similar lists of titles and descriptions? www.google.com www.teoma.com www.altavista.com/web/ [Activity]

    Slide 8:Word Spelling, Meaning, and Order

    How does capitalizing letters in keywords affect a search? Most engines ignore case How does the spelling of keywords affect a search? Most suggest alternate spellings How does making keywords plural affect a search? Most search singular forms of words as strictly that and plural as plural. How does capitalizing letters in keywords affect a search? Most engines ignore case (except for perhaps Boolean operators like AND, OR, etc.). How does the spelling of keywords affect a search? Most engines are programmed to suggest alternate spellings. How does making keywords plural affect a search?

    Slide 9:Word Spelling, Meaning, and Order

    How does using a synonym affect a search? Narrows the search bed versus garden plot bed hi-fi versus hi-fi record player phonograph How does the order of keywords affect a search? Unless you use quotes, most engines ignore order flower garden and garden flower yield similar results [Activity] How does using a synonym affect a search? Synonyms can narrow the search for words with multiple meanings, like “bed.” Use defining words (like flower or river) or use synonyms (like trundle, cradle/garden, plot) to clarify your search. Often, synonym use will reduce the number of returns and produce more desirable results, but you might miss pages with few of those keywords. As an alternative, use a Boolean operator, e.g., record player OR phonograph OR hi-fi OR turntable. (See next page) How does the order of keywords affect a search? This has little effect as most engines use proximity on the page rather than order (unless you use quotations).How does using a synonym affect a search?

    Boolean Operators Use to broaden or narrow your search AND, OR, NOT Also: + – Phrases Use quotation marks Search engine finds pages with exact word order in quotes How does the Boolean operator OR affect a search? Boolean Operators Use to broaden or narrow your search AND, OR, NOT Also: + – Phrases Use quotation marks Search engine finds pages with exact word order in quotes Use of OR will increase the number of hits as desired results must only have one of the terms you use.How does the Boolean operator OR affect a search?

    Slide 17:Word Variations Truncation

    Truncation the process of typing a special symbol at the end of a word's root form to retrieve all possible endings of that word Symbols used for truncation include the asterisk (*) and less frequently, the question mark “?”. e.g., child* will retrieve child, childhood, children, child's, etc. end truncation example: colleg* finds college, colleges, collegium, collegial internal truncation example: col*r finds color, colour, colander How do search results differ when an asterisk or question mark is used in keywords? Truncation: the process of typing a special symbol at the end of a word's root form to retrieve all possible endings of that word. Frequently used symbols for truncation include the asterisk (*) and less frequently, the question mark “?”. Use the asterisk "*" at the end of a search word or string of letters to find all words beginning with these same letters. For example, child* will retrieve child, childhood, children, child's, etc. How do search results differ when an asterisk or question mark is used in keywords?

    Slide 18:Word Variations Stemming

    Stemming Related to truncation, stemming usually refers to the ability of a search engine to find word variants such as plurals, singular forms, past tense, present tense, etc. without using truncation. Some only cover plural and singular forms.

    Slide 24:Subject Directories

    A search directory is a Web database composed of lists of Web sites categorized by subject. Best used when unsure about your exact topic Putting crayfish in a search engine would yield thousands of results. In a search directory, you could start with the topic related to crayfish that you are most concerned with: science, biology or science, zoology or food, or business What is the difference between a subject directory and a search engine? Search engines are large databases created and weighted by computer programs; subject directories are hierarchical indexes organized by human beings. Search engines are useful when you know the specific topic you’re searching for; subject directories are more useful when you need to start broad and gradually narrow your search or when you’re not sure what you’re looking for and just want to browse a particular topic. Do different directories produce similar lists of titles for subjects and subtopics? Activity How does the organization of directories for kids compare with directories for adults? Child directories are evaluated for age appropriateness, readability, interest level, and usefulness to children.
