| Locating the right information on the WWW requires effort |
| The WWW is not the first place to look | |||
| Go directly to a site -- www.irs.gov | |||
| Go to right sight -- dictionary.cambridge.org | |||
| Go to the library -- www.lib.washington.edu | |||
| Go for the kind of information you want -- www.npr.org | |||
| Ask, “What site provides this information?” | |||
| No one controls what’s published on the WWW ... it is totally decentralized | |||
| To find out, search engines crawl Web | |||
| Two parts | |||
| Crawler visits Web pages building an index of the content | |||
| Query processor checks user requests against the index, reports on known pages | |||
| Search Engine words are independent | |||
| Words don’t have to occur together | |||
| To be explicit about occurrences use Boolean queries and quotes | |||
| Logical Operators: AND, OR, NOT | |||
| monet AND water AND lilies | |||
| “van gogh” OR gauguin | |||
| vermeer AND girl AND NOT pearl | |||
| Searching strategies … | ||
| Limit by top level domains or format | ||
| Find terms most specific to topic | ||
| Look elsewhere for key words, e.g. bio | ||
| Use exact phrase only when universal | ||
| If too many hits, requery | ||
| “Search within results” using “-” | ||
| Once found, ask if site is best source | ||
| Much Web information is wrong | |||
