nternet today as a collective agency is creating 2.5 quintillion bytes of date on a daily basis and nearly 90% of all of our global data has emerged in the past 2 years.

Looking from an outsider’s perspective Big Data sounds like a good thing, which it is if we can manage to effectively handle it. For example, Atlantic Ocean stores around 100 billion billion gallons of water; if every gallon represented a byte of data, the Atlantic Ocean could only store data produced up to year 2010. From the analogy, it is clear that it is a lot of data. The tricky part is to find the useful information in this vast chunk of data. And we are creating far more data than what we were producing in 2010.

This article presents use cases of Big Data. Examples like analysing campaigns, diagnosing automotive traffic and smart news aggregation will be discussed in this article. Respective sections will discuss further details as in how big data is generated for this particular application and how is it used to generate required results.

bigdata1

Campaign Analytics

Nowadays online promotional campaigns have become a key thing for marketing and growth ventures of any business. But it can be fruitless if done without real-time insight in to the campaign. Ideally the campaign should leverage Big Data generated from previous campaigns and decide upon features like keywords, graphic design, UI/UX, demographic, etc.

The sheer volume, velocity, variety and value that is being presented by Big Data can be used to understand the customer’s requirement, relevant market development and opportunities. To make the most out of the relevant Big Data for your campaign analytics; one needs to aggregate data efficiently, create a query response system with minimum latency to analyse the data and present visual aids for statistics generated from the Big Data.

Before you start any online campaign, you need to identify your objectives. This includes getting to know your desired customers, target audience, relevant market sections. Objectifying targetable results from the campaigns which can include goals of sales number, popularity index, visibility index and others. This is to be followed by aggregating relevant data for your campaign. Big Data relevant to your campaign can be sales report of market section, customer feedback, online engagement index with previous campaigns, etc.

Once the Big Data is aggregated and analysed, business insights are created which leads to impact on both future campaigns and desired objectives. All this needs to be done because conventional sources like sales figure are not enough to predict customer’s behaviour and therefore a Big Data solution is required which delivers a transparent metrics on global marketing activities by blending multiple sources of information.

Benefit of Big Data analysis for campaign analytics can be summarized as follows:

Targeted Campaigns result in efficient allocation of marketing budget. Hence this is a smart way to boost sales without enhancing the customer acquisition cost.
Monitoring Big Data in real-time provides a way for PR team to timely respond to negative feedback for the company and its products.
Based on the response metrics, future marketing decision can be taken for better outputs.
Traffic and Diagnostics

Imagine being caught in terrible traffic on a rainy day while going to your office to attend an important meeting. You have a feeling that this will take at least couple of hours and you will miss your meeting and have serious consequences at office. Now that we have your attention, let us paint a picture where you will get live traffic diagnostics on your smart phone. You are being updated with short-cuts options which have less congested traffic and the entire fleet of city traffic is being evenly distributed in real-time to make sure that everybody reaches on time.

One of the prominent services provided in this discipline is offered by Google Maps. They predict the velocity of traffic by aggregating and averaging the velocity of individual android mobile users.

Currently this service is not very accurate because of the irregularity in vehicle sizes. This means that some android phone users may be driving a car and some may be driving a motorcycle and both of them affect the traffic in a different manner.

Efficient Fleet Management

This is a Big Data use case for delivery services who manage a large fleet of ground and air vehicles. The objective is to minimize the transportation cost and duration. This is done by analysing the data obtained from individual units of the fleet. Relevant data for efficient fleet management can be fuel-consumption metrics, data on shipment, speed data, road grades and flight routes metrics.

Transportation fleet management is required to reduce both the expenditure and their environmental footprint. Without a properly planned fleet, management will observe a climb in operations cost and decline in margin. This is why players in logistics industry have chosen to obtain insights for an efficient fleet operation. Data analysis provides actual operation assistance by avoiding empty truck and flight movement, reducing out of route miles and eradicating poorly coordinated shipments. Cherry on top is high fuel efficiency and minimized eco-footprint and all of this can be achieve by educating driving behaviour.

The Big Data for efficient fleet management is utilized by analysis done on frequently traveled. This will lead to pattern identification for routes and in turn lead to improvement in time and fuel efficiency of the fleet. With the volume of travel related data available to use, it is possible to evaluated non-congested and short routes for individual vehicles and even for entire fleet. Application like Google-Maps can be used as a visualization aid for fleet management.

One of the biggest problem for the logistics industry is empty truck or flight movement. It implied an additional cost of fuel with no logistical benefits. Proper planning of routes and shipments will eliminate this problem. Therefore to maximize the payload and efficiency, one needs to coordinates the consignments and it can be done by analysing the data in real-time which is being generated by distributed local logistical ground stations and mobile air and ground fleet.

To summarize the benefits of Big Data in this discipline:

Real time data analysis from logistic ground centers and mobile fleets will lower emissions and fuel consumption.
It will improve route planning and reduce the cases of empty truck movement.
Visual assistance for the fleet.
Intelligent News Discovery

Currently there are various online applications available who cater to your news requirements by putting together relevant articles based upon your interest. In this section, we will explore the ideas for Big Data Analysis for media production, archiving and news aggregation.

Today we have at our disposal ever-increasing amount of data in various formats originating from diverse sources such as text, video and audio. Focusing on news related articles and items, petabytes of data is generated every day and the amount seems to be growing exponentially on an annual basis. On top of it various initiatives of digitizing the data adds up the trouble of querying the relevant information and fetching it to users. Big Data solution for intelligent news discovery aims to identify, index, structure, interpret, analyse and manage media content in real-time. The result obtained from this is a relevant news-feed catered specifically for each users based upon their interest.

Benefits of Intelligent News Discovery using Big Data Analysis:

Efficient information management for online users for better and faster news aggregation.
Complete visibility for latest topics, data and facts.
Reduced cost of information management because of the automated searches and low-latency queries on complex and unstructured data.
There are various other big data use cases that can be viewed here and also all the companies that have been front runners in the space of using big data analysis to gain competitive edge in the market.

Data Mining Book Review: Machine LearningNov 2015

If you need a ML book as a teacher, Machine Learning – The art and science of algorithms that make sense of data, is definitely the one you need. It covers most ML algorithms, divided by genre (tree, rule, ensemble, etc.). From a teaching point of view, the book is quite comprehensive. From a practical point of view, some chapters can be skipped as too theoretical.

The perspective taken by Peter Flach, the author, is very different from most data mining and data science books. The focus is on math and stats rather than business problem solving. Worth a read if you need to get the theoretical concepts behind ML algorithms.

Data Science for Competitive Intelligence Aug 2015
更新于 Thu Nov 05, 2015 07:34 由 Sandro Saitta 通过 Data Mining Research
Competitive Intelligence (CI) is the process of collecting, aggregating and analyzing external data for the benefit of a company. A good introduction to the subject can be found in Competitive Intelligence Advantage: How to Minimize Risk, Avoid Surprises, and Grow Your Business in a Changing World. I particularly appreciate the use cases showing the distinction between competitive intelligence and competitor analysis. The below image provides a good view of CI.

CI

When it comes to making sense of a large amount of external data for decision making, data science is in the game. In overall, one can think of topics such as text mining, social network analysis and sentiment detection. Examples of applications in patent mining are given in the following article: Data Mining tools for technology and competitive intelligence.

The book Mining for Strategic Competitive Intelligence provides several potential applications of data mining in competitive intelligence. If you have any other references to share, please post a comment.

Big Data for Improved Efficiency in Oil and Gas Companies (Jake Goodman) Jul 2015
更新于 Mon Jul 13, 2015 03:21 由 Sandro Saitta 通过 Data Mining Research
Here is a guest post from Jake Goodman, freelance writer for online technology magazines.

With all the issues that have been surrounding global energy, a huge amount of pressure has been placed on the oil and gas industry to find new fields to explore as well as fully extract fossil fuels from wells. Regulations on production are constantly changing because of the rapid advances in the technology for extraction, and the demand for environmental protection is at an all-time high. In order for these companies to make well-informed decisions, high volumes of data need to be collected and analyzed, and from there they’ll be able to figure out what strategies to implement.

Data mining has become extremely important for oil and gas firms, with Drillinginfo’s director of data inventory John Fierstien even claiming that no one else has collected more data than the oil and gas industry, in terms of both volume and detail.

Recently, Norwegian company Ziebel announced that they gathered 1,708 terabytes of data over a period of eight months, a record breaking collection and transfer of data in global fossil fuel production. Using their unique Z System, the data compiled gave them insight on various business segments that were “applicable to well flow optimization, integrity risk control, reservoir modeling, and enhanced oil recovery, with interruption in production kept to a minimum.”

At the Offshore Technology Conference (OTC) in Houston that occurred early May, GE shared with fellow participants that had spent $1 billion over the last three years on a software center in California, where they learned how to optimize efficiency in equipment usage. They also explained to fellow participants the amount of potential that derives from big data, saying that big data analytics could foster the extraction of 80 billion barrels, which is equivalent to three years’ worth of global crude production.

Although more firms around the world are utilizing big data to give themselves a competitive edge, data mining isn’t commonly practiced in the Middle East. Three power plants are currently being built for South Oil Company in Iraq which could benefit from data mining as it would minimize obstacles in operations while preventing negative environmental impact. Adopting big data would also address future staff shortages and counteract the volatility of oil price, in turn increasing production by 8 percent, according to consulting firm Booze Allen Hamilton.

Bio

As the former business and technology editor of his university paper and a graduate of a prestigious computer science program, technology has always been his passion. He is currently freelancing with several online technology magazines while he waits for his internship to start in the fall.

我家的苞米地,一直种到邻居老刘家的后窗外。浇粪的时候,英姬问,“人家窗外那块儿就别浇了吧?”我答,“那哪儿行?浇。” 晚上,老刘回来,推开窗透气,差点熏了一跟头,气哼哼地找到我,“你在我窗外浇粪,我坚决反对!” 望着他悻悻离去的背影,我心想,哪回浇粪你不这么说?过几天还是好朋友。
