Oceans 2.0

• Described as an extension of the internet under the ocean, the Venus Coastal Observatory off Canada's west coast provides oceanographers with a continuous stream of undersea data once accessible only through costly marine expeditions. When its sister facility Neptune Canada launches next summer, the observatories' eight nodes will provide ocean scientists with an unprecedented wealth of information.

• Sifting through all that data, however, can be quite a task. So the observatories, with the help of CANARIE Inc., operator of Canada's advanced research network, are developing a set of tools they call Oceans 2.0 to simplify access to the data and help researchers work with it in new ways. Some of their ideas look a lot like such popular consumer websites as Facebook, Flickr, Wikipedia and Digg.

• And they're not alone. This set of online interaction technologies called Web 2.0 is finding its way into the scientific community.

• Michael Nielsen, a Waterloo, Ont., physicist who is working on a book on the future of science, says online tools could change science to an extent that hasn't happened since the late 17th century, when scientists started publishing their research in scientific journals.

• One way to manage the data boom will involve tagging data, much as users of websites like Flickr tag images or readers of blogs and web pages can "Digg" articles they approve.

• On Oceans 2.0, researchers might attach tags to images or video streams from undersea cameras, identifying sightings of little-known organisms or examples of rare phenomena.

• The Canadian Space Science Data Portal (CSSDP), based at the University of Alberta, is also working on online collaboration tools. Robert Rankin, a University of Alberta physics professor and CSSDP principal investigator, foresees scientists attaching tags to specific data items containing occurrences of a particular process or phenomenon in which researchers are interested.

• "You've essentially got a database that has been developed using this tagging process," he says.

• If data tagging is analogous to Flickr or Digg, other initiatives look a bit like Facebook.

• Pirenne envisions Oceans 2.0 including a Facebook-like social networking site where researchers could create profiles showing what sort of work they do and what expertise they have.

• When a scientist is working on a project and needs specific expertise — experience in data mining and statistical analysis of oceanographic data, for example — he or she could turn to this facility to find likely collaborators.

Coping

• There are a number of ways of coping There are a number of ways of coping with the Digital Delugewith the Digital Deluge

• Increasing your information processing Increasing your information processing capacitycapacity

– AcquiringAcquiring– ProcessingProcessing– StorageStorage– CommunicatingCommunicating

Coping

• Decreasing the actual amount of information that must be stored.

• More powerful compression algorithms• Avoiding unnecessary replication

Acquiring

• Improved Technology - Machines and Procedures– Faster– More Comprehensive– More Observant, Intuitive

• Search Engines• Subscription Services• User Profilers• Subject Observers• Observation/Seeking Strategies

Processing

• Representation– Efficient Sampling– Compression– Uniform representation: an analytical concept,

referring to a process which allows information from several realms or disciplines to be displayed and worked with as if it came from the same realm or discipline. The term is also applied when taking information from a number of sources, which may have used different methodologies and metrics in their data collection, and building a single large collection of information, where some records may be more complete than others across all fields of data.

• Curation• “Digital curation is the curation, preservation, maintenance,

and collection and archiving of digital assets.• Digital curation is the process of establishing and developing

long term repositories of digital assets for current and future reference[1by researchers, scientists, and historians, and scholars generally.” http://en.wikipedia.org/wiki/Digital_curation

Analysis• Data Mining: “the process of extracting hidden

patterns from data”. • As more data is gathered, with the amount of data

doubling every three years, data mining is becoming an increasingly important tool to transform this data into knowledge.

• It is commonly used in a wide range of applications, such as marketing, fraud detection and scientific discovery.

• Data mining can be applied to data sets of any size, and while it can be used to uncover hidden patterns, it cannot uncover patterns which are not already present in the data set.”

• Data mining is becoming an increasingly important tool to transform this data into information.

• It is commonly used in a wide range of applications, such as marketing, fraud detection and scientific discovery.

• Data mining is the process of using computing power to apply methodologies, including new techniques for knowledge discovery, to data.[

•  Data mining identifies trends within data that go beyond simple data analysis. Through the use of sophisticated algorithms, non-statistician users have the opportunity to identify key attributes of processes and target opportunities.

• Data mining identifies trends within data that go beyond simple data analysis.

• Through the use of sophisticated algorithms, non-statistician users have the opportunity to identify key attributes of processes and target opportunities.

• For many years, businesses and governments have used increasingly powerful computers to sift through volumes of data such as airline passenger trip records, census data and supermarket scanner data to produce market research reports.

• Continuous innovations in computer processing power, disk storage, data capture technology, algorithms, methodologies and analysis software have dramatically increased the accuracy and usefulness of the extracted information.

• The term data mining is often used to apply to the two separate processes of knowledge discovery and prediction.

• Knowledge discovery provides explicit information about the characteristics of the collected data, using a number of techniques (e.g., association rule mining)

• Forecasting and predictive modeling provide predictions of future events, and the processes may range from the transparent (e.g., rule-based approaches) through to the opaque (e.g., neural networks).

• Since the availability of affordable computer processing power in the last quarter of the 20th century, organizations have been accumulating vast and ever growing amounts of data, including, for example:– operational and transactional data

• such as sales, cost, inventory, payroll and accounting data

– nonoperational data• such as forecasts and macro economic data

– meta data• data about the data itself, such as logical

database design, data dictionary definitions, and executive summaries and scientific abstracts.

Tasks

• Classification- Arranges the data into predefined groups. – For example an email program might attempt

to classify an email as legitimate or spam.

• Clustering - Is like classification but the groups are not predefined, so the algorithm will try to group similar items together.

• Regression - Attempts to find a function which models the data with the least error.

• Association rule learning - Searches for relationships between variables. – For example a supermarket might gather

data of what each customer buys. Using association rule learning, the supermarket can work out what products are frequently bought together, which is useful for marketing purposes. This is sometimes referred to as "market basket analysis".

Applications

• Combating terrorism• It has been suggested that both the Central

Intelligence Agency and the Canadian Security Intelligence Service have employed [data mining]

• Previous data mining to stop terrorist programs under the U.S. government include

• the Total Information Awareness (TIA) program,

• Computer-Assisted Passenger Prescreening System (CAPPS II),

• Analysis, Dissemination, Visualization, Insight, Semantic Enhancement (ADVISE)

• Multistate Anti-Terrorism Information Exchange (MATRIX),

• and the Secure Flight program.

• These programs have been discontinued due to controversy over whether they violate the US Constitution's 4th amendment, although many programs that were formed under them continue to be funded by different organizations, or under different names, to this day.

• Two plausible data mining techniques in the context of combatting terrorism include "pattern mining" and "subject-based data mining".

• An example of a probable application to national security monitoring would be the ability for government analysts to define a pattern of interest as "all individuals traveling from the United States to the Middle East in the next six months" and have the ADVISE tool provide an alert whenever this pattern emerges in the data.[7
