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.

Data Mining vs Screen-Scraping

Data mining isn't screen-scraping. I know that some people in the room may disagree with that statement, but they're actually two almost completely different concepts.

In a nutshell, you might state it this way: screen-scraping allows you to get information, where data mining allows you to analyze information. That's a pretty big simplification, so I'll elaborate a bit.

The term "screen-scraping" comes from the old mainframe terminal days where people worked on computers with green and black screens containing only text. Screen-scraping was used to extract characters from the screens so that they could be analyzed. Fast-forwarding to the web world of today, screen-scraping now most commonly refers to extracting information from web sites. That is, computer programs can "crawl" or "spider" through web sites, pulling out data. People often do this to build things like comparison shopping engines, archive web pages, or simply download text to a spreadsheet so that it can be filtered and analyzed.

Data mining, on the other hand, is defined by Wikipedia as the "practice of automatically searching large stores of data for patterns." In other words, you already have the data, and you're now analyzing it to learn useful things about it. Data mining often involves lots of complex algorithms based on statistical methods. It has nothing to do with how you got the data in the first place. In data mining you only care about analyzing what's already there.

The difficulty is that people who don't know the term "screen-scraping" will try Googling for anything that resembles it. We include a number of these terms on our web site to help such folks; for example, we created pages entitled Text Data Mining, Automated Data Collection, Web Site Data Extraction, and even Web Site Ripper (I suppose "scraping" is sort of like "ripping"). So it presents a bit of a problem-we don't necessarily want to perpetuate a misconception (i.e., screen-scraping = data mining), but we also have to use terminology that people will actually use.

Coal Seam Gas - Extraction and Processing

With rapidly depleting natural resources, people around the globe are looking for new sources of energy. Lots of people don't think much of it, but doing this is an excellent ecological move forward and may even be a lucrative endeavour. Australia has one the most significant deposits of a recently discovered gas known as coal seam gas. The deposit present in areas such as New South Wales is far more significant than the others since it contains little methane and much more carbon dioxide.

What is coal seam gas?

Coal bed methane is the more general term for this substance. It is a form of natural gas taken from substantial coal beds. The existence of this material usually spelled hazard for many sites. This stopped in recent decades, when specialists discovered its potential as an energy source. It's now among the most important sources of energy in a number of countries, particularly in North America. Extraction within australia is actually rapidly developing because of rich deposits in various parts of the country.

Extraction

The extraction procedure is reasonably challenging. It calls for heavy drilling, water pumping, and tubing. Though there are a variety of different processes, pipeline construction(an initial step) is perhaps one of the most important. The foundation of the course of action can spell a real difference between the failure or success of your undertaking.

Working with a Contractor

Pipeline construction and design is serious business. Seasoned contractors may be hard to get considering the fact that Australia's coal seam gas industry is still fairly young. You'll find only a limited number of completed and working projects across the country. There are several things to consider when getting a contractor for the project.

Find one with substantial experience within the industry sector. Some service providers have operations outside the country, especially in Canada And America. This is something you should look out for, as advancement of the gas originated there. Providers with completed projects in the said area can have the solutions required for any project to take off.

The construction process involves several basic steps. It is important the service provider you work with addresses all of your needs. Below are a few of the important supplementary services to look for.

- Pipeline design, production, and installation

- Custom ploughing (to achieve specialized trenching requirements)

- Protection and repair of pipelines with the use of various liners

- Pressure assessment and commissioning

These are only the fundamentals of pipeline construction. Sourcing coal seam gas involves many others. Do thorough research to ensure the service provider you employ is capable of completing all the necessary tasks. Other elements of the undertaking include engineering plus site preparation and rehabilitation. This industrial sector may be profitable if one makes all of the proper moves.

Avoid making uninformed decisions by doing as much research as you possibly can. Use the web to your advantage to look into a company's profile. Look for a portfolio of the projects they have completed in the past. You can gauge their trustworthiness based on their volume of clients. Check out the scope of their operations and the projects they finished.

You should also think about company policies concerning the quality of their work, safety and health, along with their policies concerning communities and the environment. These are seemingly minute but important details when searching for a contractor for pipeline construction projects.
