Abstract- In this developing internet and data storage, big data implementation became extreme among organizations. In Big data processing, the data comes from numerous, heterogeneous, separate sources with complicated and developing relationships, and possesses growing. Big data is problematic to figure with victimisation most computer database management systems and desktop statistics and visual image packages. Authors has projected Map reduce programming method, a distinct progressive process extension to Map reduce, the foremost wide used framework for mining Big data. The term Big Data intracts with the act of collecting and storing Brobdingnagian amounts of information for ultimate inquiry. Map reduce is a programming model for process and generating large amount of information in parallel time. So as to decrease time interval the writers have implemented Naïve Bayes algorithm that delivers fewer maps with larger time interval.
Keywords--Big Data; Map Reduce; Naïve Bayes
Defining Big Data
With the recent introduction of Oracle Big Data Appliance and Oracle Big Data Connectors, Oracle is the initial seller to supply a whole and integrated resolution to handle the total spectrum of enterprise Big Data needs. Oracle’s Big Data strategy is targeted on the thought that you just will evolve your current enterprise information design to include Big Data and deliver business worth. By evolving your current enterprise design, you\'ll leverage the tested dependability, flexibility and performance of your Oracle systems to handle your Big Data needs.
Big data typically denotes to the ensuing types of data:
• Traditional enterprise data – contains customer info from CRM structures, transactional ERP data, web collection transactions, and overall ledger data.
• Machine-generated/sensor data – comprises Call Detail Records (“CDR”), weblogs, smart meters, business sensors, equipment logs (often mentioned to as digital expend), trading schemes data.
• Social data – contains customer feedback streams, micro-blogging places like Twitter, social media platforms similar to Facebook.
The McKinsey world Institute estimates that knowledge volume is growing four-hundredth each year, and can grow 44x between 2009 & 2020. however whereas it’s usually the foremost visible parameter, volume of knowledge isn\'t the sole characteristic that matters. In fact, there area unit four key characteristics that outline massive data:
• Volume. Machine-generated information is made in a lot of bigger amounts than non-conventional information. for instance, one response impetus engine will produce 10TB of information into equal parts hour. With very twenty five,000 aircraft flights for every day, the day by day volume of essentially this single learning supply keeps running into the Petabytes. great meters and noteworthy modern instrumentation like oil refineries and penetrating apparatuses create comparative learning volumes, mix the matter.
• Velocity. Social media data streams – while not as enormous as machine-generated data – yield a great influx of views and relationships valuable to consumer relationship management. Even at 140 characters per tweet, the high velocity of Twitter statistics ensures huge volumes (over 8 TB per day).
• Variety. Traditional information groups have a tendency to be moderately all around characterized by an information outline and change gradually. Interestingly, non-traditional information groups show a dizzying rate of progress. As new services are included, new services are added, or new advertising efforts executed, new information sorts are expected to catch the resultant data.
• Value. The economic estimation of various information changes altogether. Normally there is good information covered up among a bigger group of non-conventional information; the test is recognizing what is profitable and afterward changing and separating that information for examination.
To benefit as much as possible from big data, enterprises must advance their IT foundations to deal with these new high-volume, high-speed, high-assortment sources of information and incorporate them with the prior big business information to be examined.
The Importance of Big Data
At the point when enormous information is refined and analyzed in combination with conventional enterprise information, ventures can build up a more exhaustive and quick comprehension of their business, which can prompt upgraded profitability, a more grounded competitive position and more prominent advancement – all of which can significantly affect the main issue.
For instance, in the conveyance of social insurance administrations, administration of unending or long haul conditions is costly. Utilization of in-home monitoring devices to measure key signs, and visualization process is only one way that sensor information can be utilized to enhance patient health and decrease both office visits and healing facility induction.
At long last, online networking locales like Facebook and LinkedIn basically wouldn\'t exist without enormous information. Their plan of action requires a customized understanding on the web, which must be conveyed by catching and utilizing all the accessible information about a client or part.
Building a Big Data Platform
Similarly as with data warehousing, web stores or any IT platform, a framework for big data has novel requirements. In considering all the components of a big data platform, the true objective is to effectively incorporate your enormous information with your enterprise information to allow you to direct deep analytics on the consolidated informational data set.
The requirements in a big data infrastructure area data acquisition, data organization and data exploration.
Acquire Big Data
The obtaining stage is one of the significant changes in infrastructure from the prior days enormous information. Since enormous information alludes to data streams of higher speed and higher variety, the infrastructure required to support the securing of huge information must delivery low, predictable inertness in both catching information and in executing short, basic queries; have the capacity to deal with high exchange volumes, frequently in a distributed domain; and support flexible, dynamic information structures.
Organize Big Data
In traditional information warehousing terms, organizing data is called data integration. Since there is such a high volume of big data, there is a propensity to compose information at its initial destination location, consequently sparing both time and money by not moving around expansive volumes of data. The infrastructure required for sorting out huge information must have the capacity to prepare and control information in the first stockpiling area; bolster high throughput (often in group) to manage expansive information preparing steps; and handle a largevariety of information configurations, from unstructured to organized.
Hadoop is another innovation that permits vast information volumes to be sorted out and prepared while keeping the information on the first information storage cluster. Hadoop Distributed File System (HDFS) is the long term storage framework for web logs. These web logs are transformed into perusing conduct (sessions) by running MapReduce programs on the group and creating accumulated outcomes on a similar cluster. These accumulated outcomes are then stacked into a Relational DBMS framework.
Analyze Big Data
Since information is not generally moved amid the organization stage, the analysis may likewise be done in a distributed domain, where a few information will stay where it was initially put away and be straightforwardly gotten to from an data warehouse. The infrastruture required for analysing enormous information must have the capacity to bolster further examination, for example, statistical analysis and data mining, on a more extensive assortment of information sorts put away in differing frameworks; scale to extraordinary information volumes; deliver faster response times driven by changes in conduct; and mechanize decisions in view of scientific models. Above all, the infrastructures must have the capacity to integrate analysis on the combination of big data and traditional enterprise data. New knowledge comes not simply from dissecting new information, but rather from breaking down it inside the setting of the old to give new points of view on old issues.

A. SUPPORT VECTOR MACHINE
A support vector machine (SVM) is an idea in insights and software engineering for a set of related supervised learning strategies that analyse information and perceive designs, utilized for grouping and regression analysis. The standard SVM takes a set of input information and predicts, for each given info, which of two conceivable classes contains the info, making the SVM a non-probabilistic parallel direct classifier. Given a set of preparing cases, each set apart as having a place with one of two classifications, a SVM training algorithm builds a model that assigns new set of data into one class or the other. A SVM model is a representation of the examples as focuses in space, mapped so that the cases of the different classes are separated by an unmistakable crevice that is as wide as could be expected under the circumstances. New cases are then mapped into that same space and anticipated to have a place with a classification in light of which side of the hole they fall on.
B. NAÏVE BAYES CLASSIFIER
A Naive Bayes classifier is a probabilistic classifier in view of applying Bayes\' hypothesis with robust individuality suppositions. A more distinct term for the fundamental probability model would be \"uniqueness feature model\". Naive Bayes has a place with a gathering of group of statistical techniques that are called \'Supervised grouping\' as various to \'unsupervised grouping.\' In \' Supervised grouping\' the algorithms are advised around at least two classes to which texts have in the past been allotted by some human(s) on whatever premise.

3. Feature Extraction - Figure 4 suggests output from the parsing remains further subjected to feature extraction. The creators extricate the components by utilizing taking after methodologies, the Common Feature-based Extraction (CFBE) and Frequency-based Feature Extraction. The event of a component and the recurrence of an element. Both techniques are utilized to get Reduced Feature Sets (RFSs) which are then used to create the ARFF documents.
Figure 5. Feature Extraction
Classification - The creators utilize Naïve bayes classifier, Naïve bayes (NB) is an idea in statistics and Computer science for a set of related supervised learning strategies that examine data and recognize patterns, utilized for grouping and regression analysis. The standard NB takes a set of info information and predicts, for each given info, which of two conceivable classes includes the input, making the NB a non-probabilistic binary linear classifier. Given a set of training examples, each set apart as having a place with one of two classes, a NB training algorithm builds a model that allocates new examples into one classification or the other. Figure 6 infers a NB classifier algorithm for classifying the credit card information. Naive Bayes classifiers can be prepared proficiently in a supervised learning setting.
