Brushing up on sophisticated searching techniques
Aug 22nd, 2006 by Tom Johnson

A helpful piece posted today on LLRX.com reminding us that just throwing what we 
think might be appropriate keywords into a search engine isn't the most
sensible research strategy. While you might find that the title of the article
is not exactly what it is about, the content is helpful. Here are the main points:

“Summary of Web Search Strategies

  • Determine appropriate search engines to recover information in both the

  • Surface and the Deep Web.
  • Structure the search query with punctu­ation and groups for the maximum
    effect.
  • Use date restrictions to narrow the results.

  • Consider narrowing searches by using intitle, domain or specific site-

  • limited searches.
  • Use link checks to “Shepardize” the results.”

    Those were the days — the early days — of Social Network Analysis
    Jul 28th, 2006 by Tom Johnson

    Least any of us think that Social Network Analysis is something new, please take the time to read this wonderful, albeit personal, history of the field.   Edward O. Laumann, of the University of Chicago, has been swimming in these waters for more than 40 years.  His address to the International Network of Social Network Analysis, 26th Annual Sunbelt Conference in Vancouver, Canada, April 2006, tells much about how we have arrived at the current level of SNA

    MapInfo ties more data to maps
    May 29th, 2006 by Tom Johnson

    ''MapInfo Embraces Web Services
    by Adena Schutzberg, Executive Editor

    I'm
    trying to remember how many years ago it was that I first heard the
    vision of Web services for GIS. I suspect it was in the mid/late 1990s.
    The big Web service on everyone's list? Geocoding, also known as
    “locationally enabling datasets.”
    With MapInfo Professional v8.5, that vision is reality.

    Moshe Binyamin, senior product manager, gave me the tour, just as the product was announced for release
    on June 6 of this year. In this release MapInfo laid the groundwork for
    the
    desktop product to interact with Web services of many kinds, including
    SOAP and XML (thus RSS). This core technology allows developers to
    connect MapInfo Pro to existing Web services “with a really minor
    development effort that utilizes XML” per Binyamin.

    The first example shown was a connection to Salesforce.com,
    an online customer relationship management
    service. MapInfo developers created a sample application using MapBasic
    that, once loaded, allows users to access data records from a Salesforce.com
    account and place customer locations on the map. Alternatively, the
    user can directly link back and display full record information in the Salesforce.com app by clicking on the map.

    Geocoding customer  data from Salesforce.com


    A
    second example illustrated pulling in Yahoo traffic (via an RSS feed)
    to a MapInfo map. Yahoo uses its own XML format for this data which
    MapInfo had to “decipher” to make the application work. Most feeds,
    Binyamin suggested, would need some sort of custom parsing to be fully
    useful. The MapInfo tool automatically pulled the central ZIP Code from
    the existing
    map, allowed for a magnification level (10 mile radius or more) and the
    ability to select traffic data based on severity. This tool and its
    source code will be included as one of the sample applications that
    will ship with MapBasic v8.5.

    Resources related to Crime Mapping
    Dec 7th, 2005 by Tom Johnson

    We
    don't know if there has as yet been any empirical research done on how
    interested media consumers are in online crime mapping — and how good the coverage is —  but there is a body of
    literature debating readers' interest in crime per se.  It would
    seem to be a pretty good bet, though, that if people are interested in
    crime AND if more and more are going online via broadband, that
    some dynamic crime maps would get some hits. 

    Remember
    that crime mapping is not just about pushing digital push-pins on a
    map, GoogleMap or otherwise.  “Journey to Crime” maps or maps
    showing where a car was stolen and when it was recovered can provide
    interesting insights.

    Here are some links recently posted to the CrimeMapping listserv that could be of value to journalists:

    Indirect indicators. Or maybe not.
    Dec 5th, 2005 by Tom Johnson

    Sometimes
    journalists have a tendency to be too literal.  We want to ask a
    question and we want the response to be a quote that is without
    ambiguity.  One that's fills in some of the space between our
    anecdotes.  But other times, we need tools that work like a
    periscope, a device that allows us to not look at the object directly
    but through a helpful lens.  Such periscopes for analyzing the
    economy are indirect indicators.




    Monday's
    (5 Dec. 2005) NYTimes' Business Section was loaded with references to
    such indicators that journos could keep in mind when looking for
    devices to show and explain what's happening.  Check out “
    What's Ahead: Blue Skies, or More Forecasts of Them?”   Be sure to click on the link Graphic: Indicators From Everyday Life


    Another indirector was mentined Sunday on National Public Radio in “Economic Signs Remain Strong
      There, an economist said he tracks changes in the “titanium dioxide” data, the compound is used in all white paint and reflects manufacturing production. 








    Tilling the soil makes for fertile crops, Congressionally speaking.
    Dec 5th, 2005 by Tom Johnson

    Kudos to Derek Willis and Adrian Holovaty of The Washington Post for the Washingtonpost.com site “U.S. Congress Votes Database.”  One element we find of recent and special interest is the “late night votes
    variables for both the House and Senate.  With a little more
    probing and data slicing and dicing, it would make an interesting bit
    of visual
    statistics/infographics to do a longitudinal comparison of the time of
    votes in various congresses.





    This site/searchable database is a fine example of how investing in some basic data preparation
    can create the potential for a ton of stories.  Why, for example, do
    Democrats have such a preponderance (18 out of 20) of Representatives on the “missed
    votes
    ” list, but only 9 out of 20 on the similar list for the Senate?




    This is
    also a fine example of how a newspaper can do good things for itself
    while doing good things for the community and readers.  This
    database gives the WP reporters and editors a quick look-up of
    Congressional activity, the kind of fact and detail that can enrich a
    story.  At the same time, citizens can turn to this value-added
    form of the public record to answer their own questions.




    Derek Willis wrote to the news librarians listserv:



    “Folks,



    It's not part of a story or series, but the Post today launched a site

    that may prove useful to your newsrooms or even as an inspiration to

    learn Python: a congressional votes database that covers the

    102nd-109th congresses (1991-present). Currently browsable, we're

    working on adding a search engine and other features to it. Adrian

    Holovaty, who works for washingtonpost.com, and I assembled the data

    and he built the web framework to display it. All of the data is

    gathered using Python, the database backend is PostgreSQL and the web

    framework is Django.”








    Decentralized, complex adaptive systems meet realpolitik and journalism. Finally.
    Dec 3rd, 2005 by Tom Johnson

    A
    couple of articles have passed across our desk in recent days that
    illustrate the impact — and  importance of understanding —
    decentralized (or “distributed”) systems and
    complex adaptive systems.

    For starters, take a look at “Reinventing 911
    How a swarm of networked ­citizens is building a better ­emergency broadcast system.”

    http://www.wired.com/wired/archive/13.12/warning.html


    Author Gary Wolf writes:
    I've been talking with security experts about one of the thorniest
    problems they face: How can we protect our complex society from massive
    but unpredictable catastrophes? The homeland security establishment has
    spent an immeasurable fortune vainly seeking an answer, distributing
    useless, highly specialized equipment, and toggling its multicolored
    Homeland Security Advisory System back and forth between yellow, for
    elevated, and orange, for high. N
    ow I've come [to Portland, Oregon] to take a look at a
    different set of tools, constructed outside the control of the federal
    government and based on the notion that the easier it is for me to find
    out about a loose dog tying up traffic, the safer I am from a terrorist
    attack.

    “To understand the true nature of warnings, it helps to see them not
    as single events, like an air-raid siren, but rather as swarms of
    messages racing through overlapping social networks, like the buzz of
    gossip. Residents of New Orleans didn't just need to know a hurricane
    was coming. They also needed to be informed that floodwaters were
    threatening to breach the levees, that not all neighborhoods would be
    inundated, that certain roads would become impassible while alternative
    evacuation routes would remain open, that buses were available for
    transport, and that the Superdome was full.

    “No central authority possessed this information. Knowledge was
    fragmentary, parceled out among tens of thousands of people on the
    ground. There was no way to gather all these observations and deliver
    them to where they were needed. During Hurricane Katrina, public
    officials from top to bottom found themselves locked within
    conventional channels, unable to receive, analyze, or redistribute news
    from outside. In the most egregious example, Homeland Security
    secretary Michael Chertoff said in a radio interview that he had not
    heard that people at the New Orleans convention center were without
    food or water. At that point they'd been stranded two days.

    “By contrast, in the system Botterell created for California,
    warnings are sucked up from an array of sources and sent automatically
    to users throughout the state. Messages are squeezed into a standard
    format called the Common Alerting Protocol, designed by Botterell in
    discussion with scores of other disaster experts. CAP gives precise
    definitions to concepts like proximity, urgency, and certainty.
    Using CAP, anyone who might respond to an emergency can choose to get
    warnings for their own neighborhood, for instance, or only the most
    urgent messages. Alerts can be received by machines, filtered, and
    passed along. The model is simple and elegant, and because warnings can
    be tagged with geographical coordinates, users can customize their cell
    phones, pagers, BlackBerries, or other devices to get only those
    relevant to their precise locale.”



    Second item of interest
    I'm sure many of you noted Dexter Filkins Pg1 lead story in the NYT on
    Friday, 2 Dec. 2005.  The online version headline is “
    Profusion of Rebel Groups Helps Them Survive in Iraq
    .”  That, unfortunately, lacks the truth and insight of the print version headline:
    “Loose Structure of Rebels Helps them Survive in Iraq — While Al Qaeda Gains Attention, Many Small Groups Attack on Their Own.
     

    It
    seems that finally someone in the journalism community has figured out
    that what's happening in Iraq — and around the world — is a
    decentralize, CAS.  Too bad journalists — journalism educators, students and professionals — haven't been exposed to the
    concepts and vocabulary to really present the problem in all its, ahem,
    complexity.


    And the GIS light went on at the The Eagle-Tribune
    Nov 28th, 2005 by Tom Johnson

    This week's edition of GIS Weekly 
    tells the tale of how another newspaper figured out that GIS could be a
    vital tool for circulation.  Of course, many folks in the
    newspaper industry knew that long before word reached the editorial
    department, but no matter: more and more publishers and even some
    editors are “getting it.”  See “
    The Cultivation of Newspaper Readership Using Segmentation Software” by Susan Smith. 

    Here are some quotes:



    “We mapped the single copy purchase points to determine where they are
    and how likely prospective newspaper readers were to be near them or
    see them and we found that we could a) increase the density of our
    single copy purchase points and b) relocate them to be more in field of
    travel of likely newspaper readers. When we did that, we saw in the
    Essex County Capital newspapers, basically the North Shore of Boston,
    for example, a 25% increase in single copy sales, during the course of
    less than a year.”


    What was the company's initial investment in the software?
    “On an annual basis it's about $20,000-$30,000,” commented [
    research director Forbes] Durey. “The
    MapInfo software is priced in various stages. MapInfo's sales team was
    very flexible in designing a pricing strategy to meet our current
    needs. Our initial investment was $800-$900. We tested that for about a
    year, and then we decided to dive in and use all the data and
    capabilities that MapInfo offers. At this point, we purchased the full
    set of capabilities from MapInfo's TargetPro software. Newspapers can
    expect a varying degree of investment from $1,000 up to $30,000 or
    more.”

    If you look at
    the MapInfo investment we made, it equates to roughly 20 cents per
    subscriber per year. What fraction of the value of the subscriber is 20
    cents? In the newspaper business today it's a very small fraction.”



    Taking games seriously
    Nov 23rd, 2005 by Tom Johnson

    Serious Games Initiative

    http://www.seriousgames.org/



    The Serious Games Initiative is focused on uses for games
    in exploring management and leadership challenges
    facing the public sector. Part of its overall charter
    is to help forge productive links between the
    electronic game industry and projects involving the use of
    games in education, training, health, and public policy.





    Says information specialists Marylaine Block:



     “As one who believes nobody should be allowed to run for office until they have played



    Sim City for at least six months, I think such games have enormous



    potential for helping people explore complex social problems and possible



    solutions.”
