Super computational engine Wolf|ram Apha - a review


In its FAQ page, developers of Wolfram Alpha are quick to point out that Wolfram Alpha is not a search engine. It is described instead, as a computational knowledge engine. When a user plugs a query into the search box provided, WA generates output by doing computations and providing answers using its built-in knowledge base and algorithms, instead of searching the web and returning links.

As of now, WolframAlpha contains 10+ trillion pieces of data, 50,000+ types of algorithms and models, and linguistic capabilities for 1000+ domains. All data in WolframAlpha is centrally curated and audited bythe WA Team. This team also use a portfolio of automated and manual methods to check data, including statistics, visualization, source cross-checking, and expert review.

The lofty goal of this computational engine is to take as much of the world knowledge as possible and make it computable and accessible to everyone. Taking all the data, methods, models and algorithms accumulated during our civilization and make this immediately computable so that anyone, anywhere, can go on the web and use that knowledge to compute answers to their specific questions.

Their target group is indeed wide-ranging spanning all professions and education levels. Any level, from kindergarten to graduate school to a practitioner in the field can use this engine to get answers. For example for kindergarten students, WolframAlpha can do simple arithmetic what is 2+2, showing a step by step calculation. For the graduate student, what is the GDP of France, for the researcher how many internet users in Europe?

This seemingly super computational engine does list some of its main limitations as follows: engine can only know things that are known, and are somehow public; only deals with facts, not opinions; limits the computation time for each query; and of course, it's in continual development (continuous beta).

New 'Did You Know' video series


This is another official update to the original 'Did You Know' video series. This Fall 2009 version includes facts and statistics focusing on the changing social media landscape. Here are some interesting facts:

Did you know:

  • Over 1,000,000 books are published worldwide every year

  • Google books search scanner can digitize 1,000 pages every hour

  • Americans have access to 1,000,000,000,000 web pages; 65,000 iphone apps

  • print newspaper circulation is down 7 million over the last 25 years, BUT in the last 5 years unique readers of online newspapers are up 30 million

  • 250 million unique visitors collectively visit social network spaces such as You Tube, Face Book and My Space every month

Economic trends in libraries - ALA report



Here is an ALA press release about a new report with information on 2009 economic trends in libraries and 2010 outlook:

January 12, 2010

CHICAGO – At every turn, news reports and research indicate fairly dramatic changes in U.S. library funding, services and staffing – most occurring in the last 18 months. According to a new report prepared by the American Library Association (ALA), libraries of all types are feeling the pinch of the economic downturn while managing sky-high use.

Compiled from a broad range of available sources, The Condition of Libraries: 1999-2009 presents U.S. economic trends (2009), and summarizes trends in public, school and academic libraries across several library measures, including expenditures, staffing and services. The report also highlights trends in services provided to libraries by library cooperatives and consortia.

“This report was prepared to inform and assist library leaders as they plan in these very difficult times,” said ALA Executive Director Keith Michael Fiels. “It succinctly brings together diverse strands of data from the past decade to provide a useful benchmark for the library community and its advocates.”

As communities and academic campuses develop future fiscal plans, it is clear that all types of libraries are visibly hard hit. In a fall 2009 report prepared by the Center on Budget and Policy Priorities, 34 states had reported cuts to higher education, which impacts academic libraries; and 25 states had cut funding to K-12, which impacts school libraries. Total state budget shortfalls for fiscal year 2010 are $178 billion, and FY2011 are estimated to be roughly the same.

Public libraries also have been affected. While the full impact of the economic downturn remains fluid and the data challenging to assemble, what is known is that flat funding has been an obstacle – perhaps even a chronic problem - for many libraries this entire decade. Confirming evidence from a 2006 ALA study of public library funding, a 2009 survey conducted as part of the Public Library Funding & Technology Access Study revealed a worsening of funding – about 20 percent reported flat funding continuing in FY2010 and a majority reported budget reductions. Of those with budget cuts, about 20 percent reported 5-to-10 percent reductions in FY2010 from FY2009.

Library trends include:

School Library Media Centers
At a time when school enrollment (K-12) is growing, almost all schools reported in 2009 a decrease in funding for information resources, with a median per-student expenditure of just over $12; and
Fewer school libraries served more students in the 2006-2007 school year compared with the 2002-2003 school year; and
Total SLMC staff grew slightly, then declined in the 2006-2007 school year compared with 1999-2000.

College and University Libraries
While student enrollment at colleges and universities has declined since 2004, library use continues to increase. During a typical week in 2008, academic libraries reported more than 20.3 million visits, up from 18.7 million in 2006. They also provided more than 498,000 informational services to groups attended by more than 8.9 million students and faculty, up from 471,000 sessions attended by 8.3 million in 2006;
In fall 2008, 72 percent of academic libraries reported providing library reference service by e-mail or the Web, about the same as in 2006; and
Operating expenditures rose modestly during the period 2002 to 2008.

Public libraries
Total public library circulation and circulation of children’s materials continue to rise. Circulation of children’s materials has accounted for between 32.9 and 35 percent of total circulation between FY2002 and FY2007. Total circulation of public library materials has grown each year – up to 7.4 items per capita from about 6.8 items in FY2002;
Most public library Internet services have grown between 2006 and 2008, most notably audio and video content; and
Total public library operating expenditures have varied little year-to-year and typically align with inflation rates. Staff account for the largest portion of expenditures, followed by “other” expenditures (technology, utilities, programming, etc.) and collections.

Haiti needs our help



My thoughts and prayers are with Haitians today as they are grappling with what can best be described as a natural disaster of epic proportions. A 7.0 earthquake yesterday (January 12) may have claimed hundreds of thousands of lives. I have been viewing graphic images on the Internet, TV broadcasts and social networks.

Please lend support in anyway that you can through local or international charitable organizations. Here is a list of a few organizations:

The American Red Cross is pledging an initial $200,000 to assist communities impacted by this earthquake. They expect to provide immediate needs for food, water, temporary shelter, medical services and emotional support. They are accepting donations through their International Response Fund.

UNICEF has issued a statement that "Children are always the most vulnerable population in any natural disaster, and UNICEF is there for them." UNICEF requests donations for relief for children in Haiti via their Haiti Earthquake Fund. You can also call 1-800-4UNICEF.

Donate through Wyclef Jean's foundation, Yele Haiti. Text "Yele" to 501501 and $5 will be charged to your phone bill and given to relief projects through the organization.
