     "I welcome change but shudder though transition."
                                     Association of Research Libraries
WWW Overview

   Internet is a self-publishing medium

   It is not a library of evaluated publications selected by
    professionals

   It contains everything: excellent; biased; misinformed;
    false; opinions; personal; etc

   Everything, everything must be analysed and evaluated

               Not everything is on the Web!!!
                                                                2
WWW Overview

   Many good search tools
                                         ?


   Few are used routinely               ?



   Most people search the Web with some success

   Research shows that users think highly of their
    searching skills

                                                      3
WWW Overview

So…

   We know we search the Web
    and find useful information

             …but, let’s do it better!




                                          4
Web Searching is a Process
   Understand your information need

   Identify search tool features that support your need

   Select search tools that offer these features

   Build a search statement: browse directories / search

   Navigate & evaluate results

   Have a timer; after 15 minutes, re-evaluate your strategy


                                                           5
Useful Search Strategy?
   Know what you’re looking for …..a phone number? ……an
    expert?......product information?...... ……authoritative articles?......opinions?

   Write down your purpose in one sentence

   Brainstorm keywords and topics

   Use at least 5 keywords, more is better

   “phrase searching” is an excellent strategy

   Put the most important words first

   Vary the word forms (day / days / daylight / daytime…etc)            (Google
    does this automatically)

   Refine your search online

   Evaluate offline
                                                                                       6
Remember to:

Watch for alternative phrasing (synonyms)
        retirement / superannuation
        revenue / turnover




     Difficulty identifying US v British words?
          Eurotexte   www.eurotexte.fr/translation/tips_brit_vs_amer.shtml




     Another tool for English language slang:
          Probert Encyclopaedia      www.probertencyclopaedia.com/slang.htm

                                                                              7
WWW Overview
   Always use more than one search engine because they:

       search different databases

       have different methods of collection

       have little overlap among search engine indexes

       relevance ranking differs

         ….try   ranking.thumbshots.com or alexa.com or searchability or

                     searchengineshowdown
                                                                           8
WWW Overview
   Search for sources, not just information
           Find out what organizations are concerned with the topic

           Assume the key information will be buried in the invisible web

           Add the term ‘database’ to your search

   What do you already know?

   What do you want to know?
           Look at the following:

                 Google  Accumo  Ask  Mooter

   Be alert to new tools or tools in beta
                 A9, Google Alert, Clusty, Ansearch, Exalead
                                                                             9
Three basic types of tools:


    Search engines


    Subject Directories



    The "invisible" Web, information and multimedia that
     is stored in databases



                                                        10
Why – search engines, directories and deep web?


   Many people use search engines without considering the usefulness of
    subject directories for their topics

   The difference between these types of tools is often poorly understood

   Yahoo has such a popular directory that more selective and higher
    quality directories are often overlooked

   The invisible Web is growing at a phenomenal rate, so its content is
    becoming increasingly important when researching

   All of these tools can complement each other in the research process

   The lines are blurring between sites that offer either one resource or the
    other; for example, it is common to find directories and specialized
    searches (i.e., deep Web) at many search engine sites
                                                                        11
Subject Specific Search Engines
   Subject-specific search engines do not attempt to index
    the entire Web

   Aim for depth of coverage within a single area

   Two quick find sites for subject search engines:

       http://www.beaucoup.com/

       http://www.searchenginecolossus.com



                                                              12
When to use a search engine:

   When you have a narrow or obscure topic or idea to research

   When you are looking for a specific site

   When you want to search the full text of millions of pages

   When you want to retrieve a large number of documents on your
    topic

   When you want to search for particular types of documents, file
    types, source locations, languages, date last modified, etc.

   When you want to take advantage of newer retrieval technologies
    such as concept clustering, ranking by popularity, link ranking, and
    so on

                                        http://library.albany.edu/internet/search.html
                                                                                         13
Metasearch Engines

   Searches the databases of other search engines

   Doesn’t create its own database of information

   Can allow you to sift through results to see what
    is out there in WWW

   BUT be aware of their restrictions…


                                                     14
Metasearch Engines

   Use the results “clustering” or refining features
    of:

       Dogpile

       KillerInfo

       Vivisimo

       Mooter

       Wisenut

                                                        15
Subject Directories
   Collections of links to Internet resources, usually compiled by people,
    and organized into subject categories


   For general, research oriented queries use a subject directory

        Academic and professional directories - often created and maintained by
         subject experts to support the needs of researchers

        Commercial portals cater to the general public and are competing for
         traffic

        INFOMINE , LII and AcademicInfo are good examples of academic subject
         directories. And also try Pinakes

        Yahoo , Google and About.com are good examples of commercial portals -
         but should never be used for serious research

                                                                                16
Use subject directories if:

      you’re doing in-depth research

      you’re not familiar with your topic

      you don’t know where to start

      you want a relatively small number of substantive sites

      you want sites or ideas recommended by experts

        …use a subject directory

                                                                 17
Directory Tips
       A broad topic may be worth investigating


       Subject classification is inconsistent
        between directories


       Try this when searching:
          Search for broad topic in a directory
          Start browsing


                                                   18
Search Engine and Directory Features


   Useful site to determine features:

       How to Choose a Search Engine or Directory

            (http://library.albany.edu/internet/choose.html)




                                                               19
Invisible Web

 Information stored in searchable databases located on the
    Web


   Search engine spiders cannot or will not index this information


   Also consists of multimedia files, and files created in non-
    standard file types such as PDF


   Google includes searches of PDF files into its general searching



                                                                   20
Invisible Web
   Topic coverage is variable


   Information dynamically changing in content appears on the
    Invisible Web e.g.: news, job postings, available airline flights, etc


   Directories such as phone books, company data are a part of the
    invisible Web


   Gary Price is an authority on Invisible Web resources and has
    assembled an excellent collection at his site -

                http://www.freepint.com/gary/direct.htm


                                                                             21
When to use the invisible Web:

   When you want dynamically changing content
    such as the latest news, job postings, available
    airline flights, when you need to use a login,etc.

   When you want to find information that is
    normally stored in a database, such as a phone
    book listing, listings of lawyers, doctors, plants
    etc., searchable collections of laws, geographical
    and company data, and so on
                              http://library.albany.edu/internet/search.html
                                                                               22
Problems?

   No ‘one’ web tool catalogues, indexes or organizes the
    whole web


   Remember you are searching a database, not the web
    (perhaps the documents are not (yet) included in the database you
    are searching -- try another search engine)



   Perhaps you are using a specialized search tool that is not
    the right one for your information need
    (if looking for information in the Arts, a search engine specializing
    in the Social Sciences won’t help)
                                                                        23

         BOTTOM LINE:


Is the web page as good as or better than
what you can find in journal articles or other
            published literature



                                                 25
7 Commandments of effective Web searching

    Do not waste your time

    Believe not all you may read

    Use the appropriate tool

    Read the directions

    Be flexible in your searching

    Keep up to date

    Do not forsake the old ways (books & journals & librarians)

                                                                   26
Note: Reference your Sources!

Referencing

   Always state where you found the information!

    Write down all the details

    Web pages can be moved or removed

    …….but, they can often be accessed via archival sites


                                                            27
Practice:
Query:
 I’m looking for a specific fact/person/
  event/site/multi-concept topic

Tools:
 General search engines with a large index, good
  relevancy ranking
         e.g.:Google, Yahoo, AlltheWeb, Turboscout


                                                      28
Practice:

Query:
 I’m doing in-depth research and need help
  exploring what my topic is all about.

Tools:
 Concept clustering tools
        e.g.: Mooter, Accumo, Clusty, Vivisimo, Query
         Server


                                                         29
Practice:
   If…
       you are doing in-depth research

       you want the option to expand on your search
        with alternative topics

       you want to investigate a link ranking engine
        that does its ranking a little differently than
        Google

          ….try Ask.com
                                                          30
Practice:
   If…
       you are doing in-depth research

       you are just getting started with your topic and
        aren’t sure what it’s all about

       you don’t want results in just one, long,
        undifferentiated list

       you want to see resources on your topic organized
        into subtopics

         … try a concept clustering search engine e.g.:
        Clusty, Mooter                                      31
Practice:
   If…

       you are doing in-depth research

       you are just getting started with your topic and don't know
        much about it

       you don't want to retrieve results in just one long list

       you want to organize your thoughts about your topic by
        seeing relevant subtopics

       you want to see resources on your topic organized into
        subtopics

       your topic is somewhat obscure so a search across multiple
        sources might help

        …try Vivisimo
                                                                      32
“Split-Level” Searching

    Good general advice for getting at deep Web content,
     especially within databases




     Two-level process
    1. Search for the database site on the WWW

    2.   Search the database for the information


                                                       33
Practice: Split Level Searching
   Query:
          What Australian law firm does the solicitor Robyn
           Phillips work for?

   Tools:
          Link ranking search engines, e.g., Google, Ask.com

   Search: +lawyers +directory
          Limit to Australia
          Look for a database (e.g.findlaw.com is a database), then
           search within the database

                                                                       34
