Tamara Thompson at PI Buzz tips all of us to Census Trax. It has a ways to go to be fully functional, but it's another interesting example of what imaginative people are doing with Google Maps.
By Tamara Thompson Census Trax has amassed U.S. Census housing and demographic data, displaying it in pop-up boxes by Census block or zip code. Search by street or zip code to find population numbers and characteristics, housing types, vacancies and other data. Move your mouse around the map to get information on adjacent blocks and tracts. Census Trax currently covers only California and is free during beta testing.”
Chase Davis has an interesting entry on his blog car-case.net related to how he did a two-hour DM project at his paper in Colombia, MO.3/28/2006 Data mining: a starting point
Data mining is hard. Neural networks,decision trees – it’s a lot to chew, especially without the propertraining most of us lack. But paging through books, running failedexperiments and dealing with the associated headaches lately got me thinking: How do journalists get in on the ground floor?If data mining is the automated extraction of useful and previously unknown information from large datasets,maybe it is simply an extension of automation – a way of abstractingand scheduling searches that tap into continuous streams of data andgive reporters information they can use.

Long-time IAJ friend George Dailey, ESRI's K-12 Education Program manager, contributes a fine, basic article to the current issue of ArcUser on how to normalize census data. It's would make an especially good handout to have while teaching.See “Normalizing Census Data Using ArcMap” athttp://www.esri.com/news/arcuser/0206/files/normalize2.pdf
Recently in Santa Fe, NM there was a tragic accident when a driver plowed through the front of a shopping center medical clinic, killing three persons inside. We watched a news chopper from an Albuquerque TV station hover over the scene for at least a couple of hours. We have no idea what it costs per hour to operate a high-tech machine like that, but for small-market stations — and perhaps even newspapers — the article below (from GIS Development) suggests a relatively low-cost alternative for aerial shots.
What does this have to do with analytic journalism? For starters, think of how such aerial images could help vet and enrich infographics. Need to illustrate the real size of demonstrations such as the recent ones related to U.S. immigration policy? Here's the chance. Of course the usual caveats apply: you might want to check with your liability and workman's comp folks before letting a reporter/photographer get airborne in one of these.

Abstract:
Airborne video imaging has been used for many years for various mapping applications worldwide. Experience has shown that it is a technology that is neither well-suited to spectral remote sensing (due to its poor spectral capabilities), nor is it well-suited to spatial remote sensing (due to its poor geometric properties). Even so, airborne video imaging has proved enormously popular for some very specific mapping applications. One such application is mapping of linear infrastructure features, such as roads, pipelines or powerlines. Any country, whether developing or developed, can benefit from mapping of its linear infrastructure assets. However, to derive full benefit from this type of mapping, the data collection and processing must be both cost-effective and efficient. This paper presents an innovative yet low cost methodology for acquiring airborne video data, based on the use of an aircraft known as a powered parachute (PPC). A PPC is a low cost, simple aircraft which can fly safely at low speeds and altitudes, but still provides an extremely stable platform for imaging sensors. Tests carried out in Australia have shown it to be an ideal platform for airborne video imaging of linear features. However, the choice of platform is only part of the system – the remaining component, which is no less important, is the software that is used to process the video data. Over the years many different algorithms have been developed for mosaicking video images into continuous scenes. This paper also presents a methodology for rectifying, processing, and analysing sequential video images. The resulting combination of platform, camera and software forms an ideal system for asset mapping, which can realistically be implemented in less developed countries.<more>
A recent posting on Paul Grabowicz's listserv would seem to indicate something's afoot, at least in LA, in terms of recognizing the practitioner's need for analytic journalism.

The National Conference of State Legislatures website tracks current news by state and topic in each of the state legislatures. Their legislative bill tracking tool is better than many of the states’ own search engines, enabling searches by keywords. A unique feature is the ability to compare, on one page, all appearances of your keywords in bills in all states. The site would be perfect if you could then receive automatic updates by email or in your newsreader.
A free registration is required to save your searches at the site, then return to them later without having to reenter the search terms.
Go to the search page and enter your terms and select “exact phrase”. For example, “identity theft” returns multiple links; selecting 2006 Introduced Identity Theft Legislation takes you to a results page, organized by state, of all matching legislation.
A new site feature, reflecting the application of information tracking technology to state government, is a one page chart that lists the state legislators who have blogs and the legislative sites that offer RSS feeds.
A summary page, Crime Records and Justice Information Sharing, lists 2005 legislative bills on information technology in this field.
Comes this interesting post on the Complexity and Social Networks Blog….

Social Network Theory and its principles are applied by more and more companies in a way that some of us might not be aware of yet. So what we buy, how we rate products/services, post in forums, pictures we upload or present of ourselves on the web is significantly influencing other, likeminded individuals. In return we are influenced by the network cluster we belong to for a specific habit and the like. Collaborative filtering is a key component of using social networks for different purposes. Further information can be found here. Below you will find a list of various industry and application examples:
Social Networking plattforms There are the obvious social networking online plattforms. Among them are the open business and personal contact manegement oriented like Tribe.net , openbc, friendster or the inivitation only communities like asmallworld. Either planned or already implemented users can take advantage of added services (search functionality, messaging) by paying a monthly fee 10< USD. Furthermore, there are the rather dating/partner match making plattforms like match or eharmony.
Retail/eCommerce Most of today's ecommerce sites use collaborative filtering to improve sales, cross-,up- and downselling. A prominent example are Amazon's recommendations based on various user behaviours on their website.
Music/Radio Tapping into our musical tastes Last FM, Genielab or Pandora present us with streaming music. Here the main business model lies in linking to the respective ecommerce sites like Apple's iTunes.
Books The same applies to the area of what we might want to read next which also serves ecommerce purposes.
Movies and moreMovieLens is a free service provided by GroupLens Research at the University of Minnesota. Whether, you want to book a hotel, whole vacation there are numerous examples of collaborative filtering apps on websites.
Pictures The most prominent example for sharing, managing and searching for pictures is Flickr or myspace. The latter gaining revenues from online-ads.
Search engines As I have elaborated in an earlier entry on google bombs the network structure (ties) play an important role in search engine algorithms.
Knowledge Base and OpenSource The online encyclopedia Wikipedia builds on the power of decentralized, voluntary collaboration building an enourmous depository of multi-language information. Whether it was the development of Linux, Mozilla/Firefox or MySQL all rely on and consist of social networks. Further examples of openSource projects can be found at Sourceforge.
SNA Consulting As we can see the character and concepts of networks is mainly utilized for recommendations. Actual applications of SNA is done by a few companies and consultants like Rob Cross, IBM, Orgnet or Visiblepath. These companies try to uncover the informal networks within organisations to improve knowledge sharing, initiate change or bridging silos.

It's tough to keep track of all the various measures at various levels of government aimed at the Internet, one way or another. This essay at LLLRX.com by Beth Wellington illustrates the complexity of the topic, along with suggesting implications for all U.S. based analytic journalists.

This workshop aims to bring together researchers from different subject areas (computer scientists, computational linguistics, social scientists, psychologists, etc) in order to explore how text mining techniques can revolutionise quantitative and qualitative research methods in social sciences. New technologies from text mining (e.g. information extraction, summarisation, question-answering, text categorisation, sectioning, topic identification, etc.) which go beyond concordances, frequency counts etc can be used for quantitative and qualitative content analysis of different data types (e.g. transcripts of interviews, questionnaire analysis, archives, chatroom files, weblogs, etc). The semantic analysis of new text types, e.g. weblogs is important for sociologists and political scientists in inferring social trends. Reputation and sentiment analysis collects and identifies people’s opinions, attitudes and sentiments in text. Text mining techniques also aid metadata creation for qualitative data and facilitate their sharing.
