Thing 6 – Evaluating Information Found on the Web

Wednesday, May 30th, 2012

Reasons to Evaluate

We use the information we’ve found on the Internet or Web for a variety of purposes. Sometimes we use it for entertainment, recreation, or casual conversation. When we use the information for research, we have to be sure the information is reliable and authoritative.

That puts us in the position of having to verify information and make judgments about whether it is appropriate. We need to think critically, as opposed to using information just because it’s available to us or published on the Web.

In some situations, we don’t have to do that work on our own. Some information is screened before it comes to us. When we retrieve information from an academic or research library, either by using the Web or by visiting in person, we rely on professional librarians who have evaluated and selected the material. Information in a database that’s been prepared by a scholarly or commercial organization is often evaluated and checked for correctness before it’s made available. Articles and reports published by scholarly organizations, research labs, and government agencies often go through an independent review process before being published. Some librarians and other information specialists have established virtual libraries on the Web where they review, evaluate, and list reliable sources of information on the World Wide Web.

Here are some of those virtual libraries:

Thinking critically about information and its sources means being able to separate facts from opinions. We have to be able to verify information and know its source, we have to determine whether the facts are current, and we need to know why someone offered the data at all. After considering these issues, we can decide whether the information is appropriate for our purposes.

Goal

When we access or retrieve something on the World Wide Web we need to be able to decide whether the information is useful, reliable, or appropriate for our purposes.

Guidelines
Who is the author or institution?

    • If the author is a person, does the resource give biographical information about him or her, including any of the following: educational and other credentials, position, institutional affiliation, and street address? (Sometimes an e-mail address is not enough.)
    • If the author is an institution, is there information provided about it, including the purpose and history of the institution, in addition to a street address?
    • Have you seen the author’s or institution’s name cited in other sources or bibliographies?
    • The URL can give clues to the authority of a source. A tilde ~ in the URL usually indicates that it is a personal page rather than part of an institutional Web site. Also, make a mental note of the domain section of the URL, as follows:
.edu educational (anything from serious research to zany student pages)
.gov governmental (usually dependable)
.com commercial (may be trying to sell a product)
.net network (may provide services to commercial or individual customers)
.org organization (non-profit institutions; may be biased)
  • If the page is part of a larger institution’s Web site, does the institution appear to filter the information that appears at its site? Is the information provided put through some screening process before it is put on the Web?

How current is the information?

  • Is there a date on the Web page that indicates when the page was placed on the Web?
  • Is it clear when the page was last updated?
  • Is some of the information obviously out-of-date?
  • Does the page creator mention how frequently the material is updated?

Who is the audience?

  • Is the Web page intended for the general public, scholars, practitioners, children, etc.? Is this clearly stated?
  • Does the Web page meet the needs of its stated audience?

Is the content accurate and objective?

  • Are there political, ideological, cultural, religious, or institutional biases?
  • Is the content intended to be a brief overview of the information or an in-depth analysis?
  • If the information is opinion is this clearly stated?
  • If there is information copied from other sources is this acknowledged? Are there footnotes if necessary?

What is the purpose of the information?

  • Is the purpose of the information to inform, explain, persuade, market a product, or advocate a cause?
  • Is the purpose clearly stated?
  • Does the resource fulfill the stated purpose?

Tips

Look for the name of the author or institution at the top or bottom of a Web page.
Go to the home page for the site that hosts the information to find out about the organization.
To find further information about the institution or author use a search engine to see what related information is available on the Web.
Use the Google Groups or another tool to search archives of Usenet articles to find other information about the author or institution, and in the case of an individual to see what sorts of articles they’ve posted on Usenet.
Check the top and bottom of a Web page for the date the information was last modified or updated. If no date is present you can sometimes determine when the file holding the document or item was last modified. Most Web servers are configured to send that information along to a client.

Information on the World Wide Web About Evaluating Resources

There are several good resources on the World Wide Web to help you evaluate information. They give in-depth information about critically examining documents that appear on the Web or in print, and they offer other guidelines and suggestions for assessing Internet and Web resources.

Thing 5 – Using the Web for Research

Tuesday, May 29th, 2012

About Using the Web for Research

The Web has revolutionized the way research is done.  The Web has eliminated the need in many cases to access physical items. Articles, books, images, recordings, videos of interest to researchers are available through the Web.

This cornucopia of resources available at little or no monetary charge does come at some cost. Researchers must often fill the same role we expected from curators and librarians, evaluating and acquiring information.

Much of the following comes from Searching and Researching on the Internet and the World Wide Web 5th Edition, by Hartman & Ackermann.

Evaluate Your Information Needs

Types of Information Most Likely Found on the Internet and the World Wide Web

Current information. Many major newspapers, broadcasting networks, and popular magazines have Web sites that provide news updates throughout the day. Current Financial and weather information also is easily accessible.

Government information. Most federal, state, and local government agencies provide statistics and other information freely and in a timely manner. Most foreign governments provide official information as well.

Popular culture. It’s easy to find information on the latest movie or best-selling book.

Open access literature. Works such as Shakespeare’s plays, the Bible, Canterbury Tales, and thousands of other full-text literary resources are available. More and more academic journals are being published on the Internet in all subjects. Read more about the open access in “Open Access Movement,” by Peter Suber.

Business and company information. Not only do many companies provide their Web pages and annual reports, but several Internet-based databases also provide in-depth financial and other information about companies.

Consumer information. The Internet is a virtual gold mine of information for people interested in buying a particular item and who want opinions from other people about it. With access to everything from automobile reviews on the Web to Usenet newsgroups, consumers can find out about almost any item before they buy it.

Medical information. In addition to the hospitals, pharmaceutical companies, and nonprofit organizations that publish excellent sources of medical information, the National Library of Medicine freely provides the PUBMED database to the public.

Entertainment. The Web is the first place many people go to find games, audio files, and video clips.

Software. The Web hosts software archives in which you can search for and download software to your computer without cost.

Unique archival sites. To take one example, the Library of Congress archives Americana in its American Memory collection.

Comparing Search Engines, Meta-search Tools, & Directories

Search engines Meta-search tools Directories
  • These attempt to index as much of the Web as possible.
  • Most are full-text databases.
  • Many require knowledge
    of search techniques to
    guarantee good results.
  • They are most often used
    for multifaceted or obscure
    subjects.
  • They search very large
    databases that are created by computer programs and are updated regularly.

GoogleAskBing

  • Some allow you to search several search engines simultaneously.
  • Some supply lists of databases that can be searched directly from their pages.
  • They provide a good way to keep up with new search engines.
  • They may not fully exploit the features of individual search engines, so keep your search simple.

YippyDogpileIxquickMetaCrawler

  • These contain topic lists of selected resources, usually hierarchically arranged.
  • Most resources in these tools have been evaluated carefully.
  • They can be browsed or searched by keyword.
  • They contain links to specialized databases and subject guides.

ipl2: Information You Can Trust, Infomine, Intute,Library SpotOpen Directory Project ,

A Checklist to Help You Choose the Right Tool

Search engines and meta-search tools should be consulted when looking for the following:

  • Obscure information
  • Multifaceted topics
  • A large amount of information on a particular topic from different perspectives

Search engines and meta-search tools should not be used to find the following:

  • News that happened yesterday or even last week. You’d be better off going to a specialized database that is updated daily or weekly.
  • Information in a particular form, such as journal or newspaper articles. You’d be better off searching a specialized database that focuses on the format
  • Someone’s telephone number or email address. Certain services focus specifically on this type of information. Maps. There are special databases for maps, too.

Directories are most useful for finding the following:

  • An overview of a topic.
  • Evaluated resources.
  • Facts such as population statistics or country information.
  • A specialized database for specific or very recent information.

Databases at UMW

  • UMW Library, like many libraries, offers online access to a number of databases. These databases often lead to links to peer-reviewed, scholarly publications and periodicals.
  • It is also important to note that the Library offers several guides to periodicals and doing research.

Hands-On Activity

  • Start Firefox
  • View Go to “Zotero – Quick Start Guide,”http://www.zotero.org/documentation/quick_start_guide
  • Open another browser tab or window and go to the UMW Library information about using  Zotero. Read   the section on Zotero and UMW Library Catalogs.
  • Open another tab or browser window, go to Zotero.org and register for an account
  • Click on Tools in the menu bar, select Add-ons, find Zotero, click on preferences, and then log into your Zotero account.
  • Work on the Web researching the topic of your paper and save some materials in your Zotero account. Be sure to sync with the Zotero server before you leave.

Thing 4: Wikis

Wednesday, May 23rd, 2012

What’s a wiki?

A wiki is software that one or more people use to write and edit documents on the Web. The

wikiwiki

http://www.flickr.com/photos/kables/1220574200/, CC License

software is designed to be easy to use, and easy for people to cooperate in preparing materials. The collection of information put together with this type of software is also called a wiki.

The first wiki was developed by Ward Cunningham. The story goes that he remembered a Honolulu International Airport counter employee telling him to take the “Wiki” shuttle bus that runs between the airport’s terminals. According to Cunningham, “I chose wiki-wiki as an alliterative substitute for ‘quick’ and thereby avoided naming this stuff quick-web. ”

The most famous wiki is Wikipedia, a project started by Jimmy Wales and Larry Sanger in 2001. Wikipedia is easy to search, and the information in articles with references or citations can be checked for accuracy. The project has over 3 million articles contributed by people throughout the world. At the time of this writing it has been translated into over 200 languages. Take a look at “Wikipedia: Statistics” for details.

There are several other special-purpose wikis such as Travelerspoint, a traveler’s wiki, Jurispedia, dedicated to world-wide law, and the collection Entertainment Wikis

A public wiki is likely to be indexed by one of the major search engines so results from wikis often come up in searches using a general-purpose search engine.

Usually, each wiki page has a subject, and the entire collection of pages within a wiki can be searched by keyword. By contributing to a wiki you are adding your knowledge to the Web, which makes it a richer and more informative resource. In some wikis, editors need to register to obtain a login and password in order to edit it. In others, there is no such requirement. In Wikipedia, for example, most pages can be edited by anyone, but having an account makes it more likely that your contributions will not be deleted by someone else. Wikis can be private or public.

One of the most famous wikis is Wikipedia, a collaborative encyclopedia with millions of entries on a wide variety of topics. Thousands of people throughout the world continue to create and edit its content.

How do they work?

A wiki allows anyone to easily update and upload content on the site, typically providing a simplified interface allowing editing, page creation, and collaborative writing.

  • Most wikis allow you to see the history of page changes. This is useful when you’d like to go back and see what a page looked like before. The page history shows the name of the person who edited the page if they have a login name attached to the content update. It’s also a way for people to republish information that may have been deleted inappropriately or incorrectly.
  • Some wiki software is WYSIWYG (what you see is what you get) enabled. This means that a person can add information easily without knowing any special markup language. Other wiki software has markup language that one has to learn. Usually if there is markup language the wiki will provide a user guide to help you.
  • Some wikis software allows you to tag the wiki pages with subject keywords. These keywords can sometimes appear in tag clouds

There are many free, highly customizable platforms, including the popular Wikispaces

You can find many types of wiki software at WikiMatrix.  Some are hosted, while some require download to your computer. Wikimatrix provides a “Wiki Choice Wizard” that helps you pick and compare software packages that have features that you need.

Things to read and see

Hands-On

1. Explore Wikipedia. What is on the main page? Determine the copyright status of the material in Wikipedia.

2. In doing some research I came across the article “Unearthing the Truth About Organic Food,” by Dennis T. and Alex A. Avery, and it’s posted on a Web site produced by the Center for Global Food Issues (CGFI). Use Wikipedia to find information about CGFI. Then use Wikipedia to see who the major sponsors of the group that supports the projects of CGFI.

3. Try your hand at editing a Wiki page. I’ve sent each student an invitation (to their UMW email address) to join in the wiki  at http://cpsc104.wikispaces.com/. Accept the invitation. Working with another person try your hand at one of these.

Thing 3: Social Networking

Tuesday, May 22nd, 2012

About Social Networking

Social networking sites offer ways to not only create an online presence, but also to find others online and to establish links to one’s own personal online ‘social network.’ The social network is based around creating links of friendship to others online within the social networking community, which is reflected in social networking site names such as “Friendster.”

Six Degrees, which began in 1997 and shut down in 2001, was one of the earliest social networking sites (the name is from “six degrees of separation,” from a “small world” experiment by Yale University psychologist Dr. Stanley Milgram on social interconnectedness in 1967). Among the largest and best known sites are Facebook and MySpace, but there are also others such as Plurk. Some social networking sites are especially popular in particular countries such as Google’s Orkut, which is heavily used in Brazil; others focus on a particular interest area such as business and professional networking at Linked In, or a variety of other hobbies and shared interests at Ning and MeetUp.

As we think about social networking beyond the technology we can think that the topic of social networking is more profound than the applications we use. Here are two TED talks that amplify the notion of social networking.

How Does It Work?

Users of social networking sites register an account and then complete a profile page. Once this is done, a variety of social networking and linking options become available such as finding and ‘friending’ (establishing reciprocal links with) other users, joining a group, and/or becoming a ‘fan’ of another user. Users can post daily updates about themselves and see updates about their friends; they can also visit friends’ pages, send messages, and post comments. For some users, social networking is replacing e-mail for many of their communications.

While many sites focus around online social interaction, on other sites such as MeetUp, users can find and join groups which schedule local area activities, such as hikes, bicycling, or discussions. Some sites such as Facebook and Myspace feature ability to add customizations, plugins and widgets such as for playing online games, videos, music, and showing artworks or book collections.

Concerns

A number of concerns have been raised dealing with the expectation of privacy in these social networks,a nd the amount of privacy guaranteed.

One the one hand, some groups (typically the over-30 crowd) raise concerns about the notion of exposing one’s name, email address, interests, groups to others – some known, some unknown – within a social network implemented via technology such as Facebook. They balk at having a lower expectation of privacy in these environments than in their traditional  networks. Others though, readily join the Facebook and other Internet networks and give out personal information without giving it a second thought, or so it seems. The following articles address these issues.

Most recently Facebook changed the way it deals with what some thought was private or personal information. They put practices into place that were contrary to the expectation of privacy of Facebook’s members.

Hands On

Take a look at Plurk, Ning and MeetUp and write a summary of their differences.

Thing 2 – Microblogging

Monday, May 21st, 2012

About Microblogging

Microblogging is a form of communication that allows users to publish short pieces (usually 140 characters) of content on the Internet. The content may include text and/or links to articles, pictures, videos, or other types of media. Microbloggers create profiles and post information that others may or may not “follow.”  Twitter http://www.twitter.com is currently the most popular microblogging tool.

It allows users to send and read other users’ updates (otherwise known as tweets).  A user sends a tweet  to their Twitter account using the Twitter Web site, Web-enabled cell phone, or through another Web-based application. A very few countries allow tweets to be sent via SMS (short message system). The tweets are displayed on the user’s profile page and delivered to

other users who have signed up to “follow” them.

Users can receive updates via the Twitter website, SMS (text messaging), RSS, or through applications such as TwitterMobileTweet DeckFacebook, and Twidget.

Twitter has inspired other micro-blogging sites, including  Yammer (seeWikipedia’s list of other micro-blogging services), as well as many third-party applications, ultimately making the service easier to use as well as wildly more popular.

http://www.flickr.com/photos/27132029@N06/3022781883/

How Does Twitter Work?

Signing up for a Twitter account is free: https://twitter.com/signup

Twitter users can have “followers” to their post, or “follow” others’ posts.

Posts can appear on the Twitter home page for all to see, or posts can be made private, sent only to groups of friends. Twitter groups, trends and tags can be seen on hashtags.org.

To access information relayed via Twitter, use the Twitter search engine:http://search.twitter.com/

There is also a “Yellow Pages” directory for Twitter: http://www.twellow.com/

Twitter’s Impact on Research: Searching the Live Web

While Twitter began as a tool primarily used by individuals to let others in their community know what they were doing, it has grown to be a significant communication tool for institutions, companies, journalists (including “citizen” journalists documenting local news they have witnessed), and more.  Some recent events such as the Iranian election ,  the 2010 earthquake in Haiti,  and the 2011 earthquake and tsunami in Japan show the power of Twitter to document events that the mainstream media is unable to cover.  By searching Twitter traffic using http://search.twitter.com, we can follow live breaking news stories as they happen.  At any time of the day or night Twitter is capturing news.  The news may be as  mundane as a traffic jam on a major thoroughfare, or as tragic as a tsunami in Japan, but for those affected by an event, any news may be important.

An Important Caveat:

While Twitter traffic may be useful for research, you can’t rely on the information to be authoritative or even truthful.   It’s important to evaluate the information that is posted and not rely on it without first investigating its veracity.

15 Things about Web 2.0

Web 2.0 is the way of using the `Web so that we contribute to the Web and participate in the sharing of information – text, images, audio files, videos – in ways that build communities. Some say that it demonstrates a read/write culture, with individuals receiving (reading) information and individuals producing (writing) information sharing it with friends, family, or anyone on the Internet or part of an online community. When you think about it, television and radio are read-only. Newspapers that incorporate letters to the editor are read-write.   We’ll be looking at 15 things on the Internet that enable this notion of read-write culture.

Thing 1 – Blogs

Sunday, May 20th, 2012

About Blogs & Blogging

A blog is a frequently updated Web page that contains links to resources, personal commentaries, and opinions. In the mid-1990s, when blogs first made their appearance on the Web, there were maybe a few dozen in existence. According to Technorati’s State of the Blogosphere 2008, http://technorati.com/blogging/feature/state-of-the-blogosphere-2008/ there are over 133 million blogs. In 2004, the number was around 4.3 million.

Blogging

Take a look at  “WHO: Bloggers, Brands and Consumers – Day 1 SOTB 2010,” to read some descriptive statistics about who is blogging. If you have your own blog, then where do you fit in to those statistics?

According to Wired Magazine, Jorn Berger coined the phrase “weblog” in 1997. The Economist wrote in 2006 that “in 1999, another user, Peter Merholz, playfully broke the word into ‘we blog’, and somehow the new term—blog—stuck as both a verb and a noun.” Justin Hall is referred to as the “the founding father of personal blogging.” (http://www.nytimes.com/2004/12/19/magazine/19PHENOM.html)

One of the reasons why blogs have become so popular is the simplicity of publishing them. There is no need for the author to know HTML, and there are free blog automated publishing tools, such as Blogger, http://www.blogger.com, that make it easy for anyone to create a blog. Blogs are often defined as personal online journals, operated by individuals who compile lists of links and comment on these links to provide information that interests them, with new links on the top of the page, and older ones at the bottom. Recently, however, blogging culture has grown to include political campaigns, institutions such as libraries and museums, and virtually any entity that wants to create a community of interest around particular topics.

Blogs are also a good way to uncover news that the regular media cannot or will not cover. It is important to keep in mind that because virtually anyone can publish a blog, you must evaluate the information the blogger has provided. Make sure you can verify the author’s credentials before relying on the information that he or she has published.

How does blogging work?

There are many free, highly customizable platforms, including the most popular:

To compare blogging platforms by criteria including hosting features or system requirements, use

To search blog contents, use a blog search engine:

Much of the value of a blog is in the interaction between the author and the readers and among the readers. This takes place in the comments section of any blog post.

A bit about copyright

Sunday, May 20th, 2012

What is the notion of copyright?

Copyright was invented after the advent of the printing press and subsequent widening of public literacy.

The right by law to be the entity which determines who may publish, copy and distribute a piece of writing, music, picture or  other work of authorship.

U.S. Constitution.

Article 1, section 8

To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries;
On August 13, 1813, Thomas Jefferson wrote a letter to Isaac McPherson which included part of this debate.
If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. Its peculiar character, too, is that no one possesses the less, because every other possesses the whole of it. He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.
The full letter explains in a very eloquent way the fact that intangibles such as ideas are entirely different from physical/tangible things.

So where are we now?
