Basics of Online Web Research, Web Mining & Data Extraction Services

The evolution of the World Wide Web and Search engines has brought the abundant and ever growing pile of data and information on our finger tips. It has now become a popular and important resource for doing information research and analysis.

Today, Web research services are becoming more and more complicated. It involves various factors such as business intelligence and web interaction to deliver desired results.

Web Researchers can retrieve web data using search engines (keyword queries) or browsing specific web resources. However, these methods are not effective. Keyword search gives a large chunk of irrelevant data. Since each webpage contains several outbound links it is difficult to extract data by browsing too.

Web mining is classified into web content mining, web usage mining and web structure mining. Content mining focuses on the search and retrieval of information from web. Usage mining extract and analyzes user behavior. Structure mining deals with the structure of hyperlinks.

Web mining services can be divided into three subtasks:

Information Retrieval (IR): The purpose of this subtask is to automatically find all relevant information and filter out irrelevant ones. It uses various Search engines such as Google, Yahoo, MSN, etc and other resources to find the required information.

Generalization: The goal of this subtask is to explore users' interest using data extraction methods such as clustering and association rules. Since web data are dynamic and inaccurate, it is difficult to apply traditional data mining techniques directly on the raw data.

Data Validation (DV): It tries to uncover knowledge from the data provided by former tasks. Researcher can test various models, simulate them and finally validate given web information for consistency.

Coal Mining: Timeless Black Gems

Coal is an abundant sedimentary rock and fossil fuel used primarily as an energy source for electricity and other industrial uses such as smelting and alloy production. Coal is seldom confused with charcoal, which is primarily of wooden origin. Coal was previously used as mere household heating commodities but when the industrial revolution began, coal mining started to became large-scale. It then became an important commodity to produce electricity as well as to provide primary energy for industries as well as transportation during the 18th century to the 1950s.

Coal mining can be a very dangerous activity most especially when it involves mining underground. Gases produced can be very toxic or highly flammable, capable of explosions which can instantly kill a team of miners. Fortunately, technology has enabled companies the capacity to effectively protect their workers from the hazards of coal mining. But not only that, they can also do the same or even higher output even with significantly less number or workers.

Coal mining can involve mining underground by shaft mining or, for a more accessible and easier way, open pit mining the rock strata coal beds or coal seams. However, there are several other ways in coal mining.

Coals near the surface can be extracted by using open cut mining methods. Explosives are first used to break through the surface of the mining area and after which it is removed by draglines or by shovel and a truck. With the coal seam exposed, drills are utilized to fracture and thoroughly mine it in strips. Area mining involves drilling holes against the surface of the mining area and then planting the drill holes with explosives. When the surface is exposed, there will be a coal seam exposed. This can be extracted, mined and transported with trucks immediately. If it is still hard enough, this can also be drilled and blasted with explosives. The coal can then be collected until there is none left in the strip - then the process can be repeated to create a new mining strip. This coal mining method is most ideal for flat terrain.

One particular coal mining method is controversial. This is the mountaintop removal mining - and just as its name says, it's literally removing the mountain top, making the ridges and hill tops look like flattened plateaus. It is controversial because it drastically alters the topography as well as disturbing the ecosystem. Valleys will be filled the extracted prize and streams will be covered. The objective to coal mining was to extract these valuable energy sources, but is it really worth the damaging the environment or even risk worse consequences?

The Coal Mining Industry And Investing In It

The History Of Coal Usage

Coal was initially used as a domestic fuel, until the industrial revolution, when coal became an integral part of manufacturing for creating electricity, transportation, heating and molding purposes. The large scale mining aspect of coal was introduced around the 18th century, and Britain was the first nation to successfully use advanced coal mining techniques, which involved underground excavation and mining.

Initially coal was scraped off the surface by different processes like drift and shaft mining. This has been done for centuries, and since the demand was quite low, these mining processes were more than enough to accommodate the demand in the market.

However, when the practical uses of using coal as fuel sparked industrial revolution, the demand for coal rose abruptly, leading to severe shortage of the coal output, gradually paving the way for new ways to extract coal from under the ground.

Coal became a popular fuel for all purposes, even to this day, due to their abundance and their ability to produce more energy per mass than other conventional solid fuels like wood. This was important as far as transportation, creating electricity and manufacturing processes are concerned, which allowed industries to use up less space and increase productivity. The usage of coal started to dwindle once alternate energies such as oil and gas began to be used in almost all processes, however, coal is still a primary fuel source for manufacturing processes to this day.

The Process Of Coal Mining

Extracting coal is a difficult and complex process. Coal is a natural resource, a fossil fuel that is a result of millions of years of decay of plants and living organisms under the ground. Some can be found on the surface, while other coal deposits are found deep underground.

Coal mining or extraction comes broadly in two different processes, surface mining, and deep excavation. The method of excavation depends on a number of different factors, such as the depth of the coal deposit below the ground, geological factors such as soil composition, topography, climate, available local resources, etc.

Surface mining is used to scrape off coal that is available on the surface, or just a few feet underground. This can even include mountains of coal deposit, which is extracted by using explosives and blowing up the mountains, later collecting the fragmented coal and process them.

Deep underground mining makes use of underground tunnels, which is built, or dug through, to reach the center of the coal deposit, from where the coal is dug out and brought to the surface by coal workers. This is perhaps the most dangerous excavation procedure, where the lives of all the miners are constantly at a risk.

Investing In Coal

Investing in coal is a safe bet. There are still large reserves of coal deposits around the world, and due to the popularity, coal will be continued to be used as fuel for manufacturing process. Every piece of investment you make in any sort of industry or a manufacturing process ultimately depends on the amount of output the industry can deliver, which is dependent on the usage of any form of fuel, and in most cases, coal.

One might argue that coal usage leads to pollution and lower standards of hygiene for coal workers. This was arguably true in former years; however, newer coal mining companies are taking steps to assure that the environmental aspects of coal mining and usage are kept minimized, all the while providing better working environment and benefits package for their workers. If you can find a mining company that promises all these, and the one that also works within the law, you can be assured safety for your investments in coal.

Dear Donna: Tread Lightly When Suggesting 'Man-Scaping'

Dear Donna,

A man I recently began dating needs some "man-scaping." I would find him much more appealing if he trimmed the hair in his ears and nose and on the back of his neck. He has hinted that he is buying me something for Valentine's Day. Do you think it would be appropriate to buy him a gift certificate to a spa and tell him he could benefit from some "man-scaping?" - Anonymous

Dear Anonymous,

Since Valentine's Day is about love and romance, I would not put the focus on "man-scaping" by buying him a gift certificate to a spa. There is no easy, tactful way to suggest to someone that they do something about ear and nose hair. One day when you are sitting close to him, whisper in his ear, "I think you could use some "man-scaping." After you explain what "man-scaping" is, be ready with the card to the spa.

Dear Donna,

I am in my 40s, single and dating for the past five years. I meet men mostly through friends, work and online. The last two men I met assumed we would split the bill after lunch or dinner. The first one caught me off guard so I paid. I also immediately decided I would not see him again. The second added up my half of the bill and asked me what kind of tip I thought was appropriate. I told him I thought he should pay, and the date went downhill from there. Whatever happened to the gentleman pays? - Sarah

Dear Sarah,

This is a side effect of online dating. When you are meeting multiple women, it can be expensive to always be the one paying. If you are meeting someone for the first time, keep it simple. Agree to meet for one hour and not over lunch or dinner. Most men do not expect a lady to split the cost of a cup of coffee or a glass of wine. Bottom line, if he is interested in you, he gladly will pay.

Top Tips for Data Mining Success

You may have trieTips for data mining successd data mining before but you seem to be lost in the maze of confusion, data overload, and a number of strange terms and icons. Do not fret, you are not alone. There may be a number of first timers who are in the same boat as you do. Stop, refocus and start all over again with the following tips in mind.

It is important that proper handling of the data mining procedure must be employed. Easy as it may sound, it can only bring in great results when it is placed in the expert hands and when done according to the right patterns and processes. This is not to say that data mining is only successful for a gifted and trained few. It means serious consideration, preparation, and training must be part of the groundwork before disembarking into it.

The most practical and tested tips are: know your desired outcomes; set expectations; assign the right personnel; avoid data dump; create a deployment scheme; develop a maintenance plan.

Know your desired outcomes

As the major proprietor of your business, you of all people should have a clear view in mind of what you really want for your business. Thus, before trying on new strategies and techniques that are recommended to you, you must know what your desired outcomes are. For instance, if your business is in real estate, you must be able to foresee which direction your market should go. Are you going up on skyscrapers or towards the horizons in the countryside? From great lengths, you go to the specifics and clearly spell out what you want and where it should be.

Set expectations

In connection with identifying your outcomes, you must also set realistic and attainable expectations. These are the very things that preclude possible obstacles and frustrations in the coming years. You can see where your business is going by web research or data mining. You can see the past and present of your competitors and you can also set your own future based on the experiences of others. It is often wise to set expectations that you have not attained before. It is like plowing and preparing the ground because you know rain is coming and it is the right time to plant and gain great harvest.

Assign the right personnel

When you find the right person as well as the right data mining service, you can cut short tiresome planning, devising and preparation. If you are in a small enterprise, you can spearhead the procedure but if you have enough staff at your disposal, choose one who is not only knowledgeable but also reliable and dedicated. You do not want someone who is only a good starter and one who would leave you hanging when the going gets tough.

Avoid data dump

Being sure of what you want can help you avoid unnecessary data. Data mining like real mining is being able to know where the gold is and is able to get it done in the most efficient and effective way. Being able to identify the legal sites and reliable, well researched information is the short cut to finding the right and exact data. It would be a waste of time and effort if you are aimlessly opening and clicking on unsure and ambiguous websites. There are a lot of links that lead you to more links and are simply making money out of others’ ignorance.

Create a deployment scheme

Like any other venture, you must also be able to delegate the task as well as the information that you gather. Since you are not a superhuman, learn to seek the assistance of others and be sure that you know who to trust. In addition, you must have a classification and segregation of the needed materials so that these will be easy to locate and analyze. In other words, order and proper organization is another tip in order to achieve success in data mining.

Develop a maintenance plan

Finally, along with orderliness and efficiency, you must see to it that you have an effective maintenance plan. What to do with old data and where to store the vital ones are concerns that need to be considered too. In addition, there is a need for a watchdog in the whole duration of your business venture. This will not only assure you of security of your data but also keep you on healthy and solid ground. This maintenance can be both a cleaning and healing spot for your business’ overall life and sustainability.

So much can be said about how to go about with your business using data mining but there is a factor that is uniquely your own. Above and beyond all these techniques and strategies, trust your instincts. You are the better judge of your desires and actions; thus, you must spend time alone in reflection, contemplation and retrospection. Being silent and alone can make you see things that are missed among all the movements and noise. Once in a while, leave the scene and look objectively at your work. Remember, there is wisdom in alienation and objectivity.
