Data mining (the analysis step of the "Knowledge Discovery in Databases" process, or KDD), an interdisciplinary subfield of computer science, is the computational process of discovering patterns in large data sets ("big data") involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. 

The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. Aside from the raw analysis step, it involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating. 

The term is a misnomer because the goal is the extraction of patterns and knowledge from large, amount, of data, not the extraction of data itself. It also is a buzzword and is frequently applied to any form of large-scale data or information processing (collection, extraction, warehousing, analysis, and statistics) as well as any application of computer decision support system, including artificial intelligence, machine learning, and business intelligence. 

The popular book "Data mining: Practical machine learning tools and techniques with Java" (which covers mostly machine learning material) was the Originally to be named just "Practical machine learning", and the term "data mining" was only added for marketing; reasons. Often the more general terms "(large scale) data analysis", or "analytics" – or when referring to actual methods, artificial intelligence and machine learning – are more appropriate.

The actual data mining task is the automatic or semi-automatic analysis of large quantities of data to extract previously unknown, interesting patterns such as groups of data records (cluster analysis), unusual records (anomaly detection), and dependencies (association rule mining). This usually involves using database techniques such as spatial indices. These patterns can then be seen as a kind of summary of the input data, and may be used in further analysis or, for example, in machine learning and predictive analytics. For example, the data mining step might identify multiple groups in the data, which can then be used to obtain more accurate prediction results by a decision support system. Neither the data collection, data preparation, nor result interpretation and reporting is part of the data mining step, but do belong to the overall KDD process as additional steps.

The related terms data dredging, data fishing, and data snooping refer to the use of data mining methods to sample parts of a larger population data set that are (or may be) too small for reliable statistical inferences to be made about the validity of any patterns discovered. These methods can, however, be used in creating new hypotheses to test against the larger data populations.

Etymology ==>
In the 1960s, statisticians used terms like "Data Fishing" or "Data Dredging" to refer to what they considered the bad practice of analyzing data without an apriori hypothesis. The term "Data Mining" appeared around 1990 in the database community. For a short time in 1980's, a phrase "database mining"™, was used, but since it was trademarked by HNC, a 

San Diego-based company, to pitch their Database Mining Workstation; researchers consequently turned to "data mining". Other terms used include Data Archaeology, Information Harvesting, Information Discovery, Knowledge Extraction, etc. Gregory Piatetsky-Shapiro coined the term "Knowledge Discovery in Databases" for the first workshop on the same topic (KDD-1989) and this term became more popular in AI and Machine Learning Community. However, the term data mining became more popular in the business and press communities. Currently, Data Mining and Knowledge Discovery are used interchangeably. Since about 2007, "Predictive Analytics" and since 2011, "Data Science" terms were also used to describe this field.

Background ==>
The manual extraction of patterns from data has occurred for centuries. Early methods of identifying patterns in data include Bayes' theorem 1700's, and regression analysis 1800's. The proliferation, ubiquity and increasing power, of computer technology has dramatically increased data collection, storage, and manipulation ability. As data sets have grown in size and complexity, direct "hands-on" data analysis has increasingly been augmented with indirect, automated data processing, aided by other discoveries in computer science, such as neural networks, cluster analysis, genetic algorithms (1950s), decision trees and decision rules (1960s), and support vector machines (1990s). 

Data mining is the process of applying these methods with the intention of uncovering hidden patterns in large data sets. It bridges the gap from applied statistics and artificial intelligence (which usually provide the mathematical background) to database management by exploiting the way data is stored and indexed in databases to execute the actual learning and discovery algorithms more efficiently, allowing such methods to be applied to ever larger data sets.

Research and evolution ==>
The premier professional body in the field is the Association for Computing Machinery's (ACM) Special Interest Group (SIG) on Knowledge Discovery and Data Mining (SIGKDD). Since 1989, this ACM SIG has hosted an annual international conference and published its proceedings, and since 1999 it has published a biannual academic journal titled "SIGKDD Explorations".

Process ==>
The Knowledge Discovery in Databases (KDD) process is commonly defined with the stages:

(1) Selection
(2) Pre-processing
(3) Transformation
(4) Data Mining
(5) Interpretation/Evaluation. 
It exists, however, in many variations on this theme, such as the Cross Industry Standard Process for Data Mining (CRISP-DM) which defines six phases:

(1) Business Understanding
(2) Data Understanding
(3) Data Preparation
(4) Modeling
(5) Evaluation
(6) Deployment

==> or a simplified process such as 
(1) pre-processing, 
(2) data mining, and 
(3) results validation.

Polls conducted in 2002, 2004, 2007 and 2014 show that the CRISP-DM methodology is the leading methodology used by data miners. 

 The only other data mining standard named in these polls was SEMMA. However, 3-4 times as many people reported using CRISP-DM. Several teams of researchers have published reviews of data mining process models, and Azevedo and Santos conducted a comparison of CRISP-DM and SEMMA in 2008. 

Pre-processing ==>
Before data mining algorithms can be used, a target data set must be assembled. As data mining can only uncover patterns actually present in the data, the target data set must be large enough to contain these patterns while remaining concise enough to be mined within an acceptable time limit. A common source for data is a data mart or data warehouse. Pre-processing is essential to analyze the multivariate data sets before data mining. The target set is then cleaned. Data cleaning removes the observations containing noise and those with missing data.

Data mining ==>
Data mining involves six common classes of tasks: 

Anomaly detection (Outlier/change/deviation detection) – The identification of unusual data records, that might be interesting or data errors that require further investigation.

Association rule learning (Dependency modeling) – Searches for relationships between variables. For example, a supermarket might gather data on customer purchasing habits. Using association rule learning, the supermarket can determine which products are frequently bought together and use this information for marketing purposes. This is sometimes referred to as market basket analysis.

Clustering – is the task of discovering groups and structures in the data that are in some way or another "similar", without using known structures in the data.
Classification – is the task of generalizing known structure to apply to new data. For example, an e-mail program might attempt to classify an e-mail as "legitimate" or as "spam".
Regression – attempts to find a function which models the data with the least error.
Summarization – providing a more compact representation of the data set, including visualization and report generation.

Results validation ==>
Data mining can unintentionally be misused, and can then produce results which appear to be significant; but which do not actually predict future behavior and cannot be reproduced on a new sample of data and bear little use. Often this results from investigating too many hypotheses and not performing proper statistical hypothesis testing. A simple version of this problem in machine learning is known as overfitting, but the same problem can arise at different phases of the process and thus a train/test split - when applicable at all - may not be sufficient to prevent this from happening.

This section is missing information about non-classification tasks in data mining. It only covers machine learning. Please expand the section to include this information. Further details may exist on the talk page. (September 2011)

The final step of knowledge discovery from data is to verify that the patterns produced by the data mining algorithms occur in the wider data set. Not all patterns found by the data mining algorithms are necessarily valid. It is common for the data mining algorithms to find patterns in the training set which are not present in the general data set. This is called overfitting. To overcome this, the evaluation uses a test set of data on which the data mining algorithm was not trained. The learned patterns are applied to this test set, and the resulting output is compared to the desired output. 

For example, a data mining algorithm trying to distinguish "spam" from "legitimate" emails would be trained on a training set of sample e-mails. Once trained, the learned patterns would be applied to the test set of e-mails on which it had not been trained. The accuracy of the patterns can then be measured from how many e-mails they correctly classify. A number of statistical methods may be used to evaluate the algorithm, such as ROC curves.

If the learned patterns do not meet the desired standards, subsequently it is necessary to re-evaluate and change the pre-processing and data mining steps. If the learned patterns do meet the desired standards, then the final step is to interpret the learned patterns and turn them into knowledge.

Standards ==>
There have been some efforts to define standards for the data mining process, for example the 1999 European Cross Industry Standard Process for Data Mining (CRISP-DM 1.0) and the 2004 Java Data Mining standard (JDM 1.0). Development on successors to these processes (CRISP-DM 2.0 and JDM 2.0) was active in 2006 but has stalled since. JDM 2.0 was withdrawn without reaching a final draft.

For exchanging the extracted models – in particular for use in predictive analytics – the key standard is the Predictive Model Markup Language (PMML), which is an XML-based language developed by the Data Mining Group (DMG) and supported as exchange format by many data mining applications. As the name suggests, it only covers prediction models, a particular data mining task of high importance to business applications. However, extensions to cover (for example) subspace clustering have been proposed independently of the DMG. 

Notable uses ==>
Main article: Examples of data mining

 ==> See also: Category: Applied data mining.
Data mining is used wherever there is digital data available today. Notable examples of data mining can be found throughout business medicine, science, and surveillance.

Privacy concerns and ethics ==>
While the term "data mining" itself has no ethical implications, it is often associated with the mining of information in relation to peoples' behavior (ethical and otherwise). 

The ways in which data mining can be used can in some cases and contexts raise questions regarding privacy, legality, and ethics. In particular, data mining government or commercial data sets for national security or law enforcement purposes, such as in the Total Information Awareness Program or in ADVISE, has raised privacy concerns. 

Data mining requires data preparation which can uncover information or patterns which may compromise confidentiality and privacy obligations. A common way for this to occur is through data aggregation. Data aggregation involves combining data together (possibly from various sources) in a way that facilitates analysis (but that also might make identification of private, individual-level data deductible or otherwise apparent). 

This is not data mining per se, but a result of the preparation of data before – and for the purposes of – the analysis. The threat to an individual's privacy comes into play when the data, once compiled, cause the data miner, or anyone who has access to the newly compiled data set, to be able to identify specific individuals, especially when the data were originally anonymous. 

It is recommended that an individual is made aware of the following before data are collected: 

the purpose of the data collection and any (known) data mining projects;
how the data will be used;
who will be able to mine the data and use the data and their derivatives;
the status of security surrounding access to the data;
how collected data can be updated.

Data may also be modified so as to become anonymous so that individuals may not readily be identified. However, even "de-identified"/"anonymized" data sets can potentially contain enough information to allow identification of individuals, as occurred when journalists were able to find several individuals based on a set of search histories that were inadvertently released by AOL. 

Situation in Europe ==>
Europe has rather strong privacy laws, and efforts are underway to further strengthen the rights of the consumers. However, the U.S.-E.U. Safe Harbor Principles currently effectively expose European users to privacy exploitation by U.S. companies. As a consequence of Edward Snowden's Global surveillance disclosure, there has been increased discussion to revoke this agreement, as in particular the data will be fully exposed to the National Security Agency, and attempts to reach an agreement have failed. 

Situation in the United States ==>
In the United States, privacy concerns have been addressed by the US Congress via the passage of regulatory controls such as the Health Insurance Portability and Accountability Act (HIPAA). The HIPAA requires individuals to give their "informed consent" regarding information they provide and its intended present and future uses. 

According to an article in Biotech Business Week', "'[i]n practice, HIPAA may not offer any greater protection than the longstanding regulations in the research arena,' says the AAHC. More importantly, the rule's goal of protection through informed consent is undermined by the complexity of consent forms that are required of patients and participants, which approach a level of incomprehensibility to average individuals." This underscores the necessity for data anonymity in data aggregation and mining practices.

U.S. information privacy legislation such as HIPAA and the Family Educational Rights and Privacy Act (FERPA) applies only to the specific areas that each such law addresses. Use of data mining by the majority of businesses in the U.S. is not controlled by any legislation.

Copyright Law 
Situation in Europe 
Due to a lack of flexibilities in European copyright and database law, the mining of in-copyright works such as web mining without the permission of the copyright owner is not legal. Where a database is pure data in Europe there is likely to be no copyright, but database rights may exist so data mining becomes subject to regulations by the Database Directive. On the recommendation of the Hargreaves review, this led to the UK government to amend its copyright law in 2014 to allow content mining as a limitation and exception. Only the second country in the world to do so after Japan, which introduced an exception in 2009 for data mining. 

However, due to the restriction of the Copyright Directive, the UK exception only allows content mining for non-commercial purposes. UK copyright law also does not allow this provision to be overridden by contractual terms and conditions. The European Commission facilitated stakeholder discussion on text and data mining in 2013, under the title of Licences for Europe. The focus on the solution to this legal issue being licenced and not limitations and exceptions led to representatives of universities, researchers, libraries, civil society groups and open access publishers to leave the stakeholder dialogue in May 2013. 

Situation in the United States ==>

By contrast to Europe, the flexible nature of US copyright law, and in particular fair use means that content mining in America, as well as other fair use countries such as Israel, Taiwan, and South Korea, is viewed as being legal. As content mining is transformative, that is it does not supplant the original work, it is viewed as being lawful under fair use. 

For example, as part of the Google Book settlement the presiding judge on the case ruled that Google's digitization project of in-copyright books was lawful, in part because of the transformative uses that the digitisation project displayed - one being text and data mining

Data Mining Vs Artificial Intelligence Vs Machine Learning - Upfront Analytics
When talking about artificial intelligence and machine learning, public knowledge lands somewhere between understanding computers and getting information from a Tom Cruise movie. There's a lot of misinformation and misunderstanding around what computers can and can't do. Unfortunately, while artificial intelligence might not be as sensational as a summer blockbuster, it's just as exciting in the market research industry.

Top 5 Ways Organizations can benefit from Data Mining

Data mining is a computational process used to discover patterns in large data sets. How companies can benefit-

All commercial, government, private and even Non-governmental organizations employ the use of both digital and physical data to drive their business processes.the benefits of data mining

Data mining is widely used to gather knowledge in all industries. For those unfamiliar with the concept, a definition of the different types of data mining – along with the benefits to all organizations, is in order.

The most comprehensive definition of this term is "an interdisciplinary, subfield of computer science, data mining is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems."

In laymen terms, data mining is the use of computers and specific software applications to arrange data, process it and provide a usable data output or information as specified by the user.

Where can Data be Sourced from?

As stated above, data can be mined or found through the use of digital tools as well as physical methods from different sources. There are numerous sources a data mining company gets its raw data from across both the digital and physical world and these sources include the following:

1.) Website Data Mining: When launching a new product or services online, the need to conduct a market research usually drives the need for mining websites for relevant data to simplify your research effort. Therefore, mining data from websites simply means the use of research tools to get relevant data from websites, e-commerce stores, online journals etc.

2.) Social Media Data Mining: Today’s most popular means of communication is also one of the most important sources available for researchers. Data mining companies use social media to get the required information to drive their market/organizational analysis.

3.) Business Data Mining: Competing businesses and organizations get data from company records on their working personnel or business processes for use in their own business research. Excel or Document Mining: When searching for data on the web, focus should be placed on getting relevant documents—such as Excel, Ms, Word and PDF files—with information or data on the topic of your research.

4.) Resume Information Mining: Resumes of job applicants can tell you a lot about human resources, filling up job applications or posting job opportunities for the general public. Therefore streamlining your mining effort to include resume research is a sure way of getting more balanced information about a particular subject.

5.) Music Mining: Other sources for dredging up data such as music mining, visual mining, and sensor mining also exist and are used for more specific organizational needs

The benefits of Data Mining

Lederhosen, -pickax-murderer, The benefits of mining data covers almost all facets of life which include; gaming, policing, business, science, engineering, human rights organizations and surveillance.

When dealing with a plethora of data sources, confusion usually arises for the incompetent researcher who has neither the tools nor experience to handle bulky projects. Outsourcing data mining projects reduces the risk of dredging up ineffective data.

Data mining helps organizations get the necessary information needed to handle different processes as quickly as possible. For the surveillance and policing industries, the need to meet deadlines and process information quickly is of the utmost importance.

Outsourcing bulky data mining projects ultimately helps an organization manage its human resources, its capital expenditures and focus on core business areas.

Learning to Use Big Data the Right Way - Technology 

News Archives - Colocation America

Big data still means big data. If you know what big data means and how to use it—good for you. If you don’t, then you’re in the same boat as many of us. 

Big data has slowly become a buzzword—something that gets said repeatedly but has an ambiguous meaning. 

On the surface, big data means storing large amounts of data and playing connect the dots to glean a trend through a specific algorithm. It’s called “big data” because there’s too much information for human beings to sift through. It’s like trying to find the grain of salt on the beach. 

But What Does Big Data Really Mean?

Our friends at Wikipedia can bore you for ages about the topic, and our more focused friends at arsTechnica can give you a more reader-friendly explanation, but ours is simple: Big data is what computers were designed for in the first place. 

Throw away the endless files and papers and store all the information on a machine where that machine can analyze the information while you do something else. 

A great example of how big data is used is a basic Google search. Imagine typing an inquiry and waiting for some person at Google to sift through endless pages of the internet until he/she gets back to you with your answer a good week or so later. Instead, the answer is instantaneous because Google’s algorithms have already done all the work. Brilliant! 

How Can You Use Big Data?

But on a smaller scale, let’s say your business, how is big data applicable. Your business most likely does not have the resources that Google has. Instead, maybe you own a law firm and you want to analyze which stipulation in a lawsuit ends well or worse during Trials; That would give you a better idea of whether or not to take (and win) the case. 

You have all this data lying around, it’s up to you to sort through all the variables. Or rather, it’s up to you to find the correct software to do that for you. Maybe take a dedicated server (and you’ll need one with all the data you’ll be analyzing) and store all the “big data” on there while your software does the work for you. That’s it. There’s plenty of software out there to suit your specific needs. 

Now get out there and use big data to get big results. 


Big Data – two words that get tossed around quite feverishly yet there’s only a small group of people who actually know how to harness it, the right way.

Over the last couple of years, you may have heard the words “Big Data” pop up in feverish boardroom meetings or a variety of tech-savvy publications. However, there is only a handful of people in the industry who have recognized the underlying potential and implications of big data as a business tool.

Big data is simply the combination of structured and unstructured data aggregated by a company. It has no inherent business value of its own, and its true value is only created after extensive evaluation and analysis.

The real value of big data lies in your ability to zero down on the information that will give you essential consumer insights regarding your products. This will allow you to optimize your organization’s business strategies in order to target consumer needs more accurately.

What Drives the Consumer Life Cycle?

The innovation of big data is a key facilitator of the new marketing paradigm that encourages organizations to abandon conventional, monotonous marketing models in favor of customized and strategic plans. Big data allows you to harness essential results across the whole spectrum of the standard customer life cycle, which allows them to understand their success and shortcomings in each field.

The objective of every marketing model is to achieve brand ubiquity across all the organizational channels utilized to market your products. Big data essentially gives you the most accurate insights into the mindset of your consumers that will help you accordingly tweak your strategies to target your user base perfectly and attract a lot more customers.;

Even if you own a company marketing something highly technical and mundane like GPS heavy machinery, you can still devise a creative engagement plan to captivate the attention of your target audience.

Harnessing Customer Intelligence

Consumer intelligence is what we classify as the data aggregated by your company after a phase of customer interaction. Each campaign launched by your organization generates a massive quantity of data.

However, the quality of data is what really matters at the end of the day. The true value of customer intelligence is determined by the depth of the insights it gives you for promoting your brand during every possible stage of your marketing campaign.

This helps you draw out better marketing strategies that target and serve each segment of your user base and ensure all their needs are adequately met with.

Consumer Life Cycle

The consumer life cycle is the driving force of any big data engine, and in turn, the power of the big data engine is what helps your company’s marketing campaign hit a home run. Hence, it is important to prioritize the right data to extract and analyze rather than be drowned in a sea of irrelevant information.

A well-implemented data engine can help you build the perfect bridge of harmony that you always dreamed of between your customers and your organization.
