Web Data Extraction Solutions for business Automation

Your business today is driven purely and solely by information. This vital component is carved out from data scraped from relevant sources, cleansed and compiled to form the crux of your enterprise analytics plan. Therefore, following a manual practice for Data Extraction often makes it prone to errors which may be detrimental to the health of your business. Various Web Data Extraction Solutions therefore are made available which help to not only automate Website Data Scraping, but in the process also help in the automation of several business processes.  Let us take a look at some of these business processes:

Execute Data Mining

One of the most obvious usages of the data extractor tools is the function of Web Data Mining, which, if done through manual processes is neither cost-effective nor accurate. Therefore, data extraction solutions provide simple and convenient point and click data extraction interfaces. Moreover, these do not require any additional programming knowledge.

Validate Data accuracy

Web Site Data scraping tools use advanced technology to not only extract data, but also validate their accuracy. This is particularly beneficial for businesses which are involved in background screening and credit reporting activities. Automating the process of validating records helps in increasing turnaround time of the business and ensures accuracy, two of the most crucial criteria for achieving success in their line of business.

Be Price Wise

Organizations are always involved in studying the price dynamics in order to better understand the challenges and areas of opportunities. Your awareness on these helps you to provide more competitive pricing for your products and services. Data extraction solutions are equipped with pricing intelligence technology that helps to collect data on the price that your customer’s expect, their feedback on your products and services and helps you develop insights on products being launched by competitors, their price and availability. This automated process therefore ensures the following things for your business:

•    Increased market – share

•    Enhanced product strategy

•    Informed decisions

Be Compliance Ready

If yours is a financial services firm, you must have often found it to be a major challenge to keep yourself abreast of the compliance and risk factors. Tracking the myriad watch lists, sanction lists and federal and state regulations, available on the web is not only time taking but also an expensive endeavor. The automated Web Data Mining tools ensure that you are now able to do this without impacting the time and money aspect of your business. You are now ensured of compliance with all regulations and sanction lists that are updated on a regular basis. Consequently, your business can also breathe easy with a reduced exposure to financial fraud and identity theft.

Easy Access to Customer Feedback

Your customers are in a way the real owners of your business. They define the way you need to design your product strategy. It is therefore crucial that you need to listen to what they have to say.  The automated Web extraction solutions with their ability to tap into several relevant sources help you to get access to customer sentiments and feedback on your products and services. This is a vital aspect in your organization's growth as it helps you to tackle three important factors:

•    Assimilate positive or negative vibes on your newly launched product or service which might require you to revisit your product strategy

•    Provide immediate attention to issues, if any, with any particular product

Create a trend of aggregated customer sentiments, for analysis

Scraping a website from a windows service

Question

Hi there.  I have a windows forms application that scrapes a website to retrieve some data.  I would like to implement the same functionality as a windows service.  The reason for this is to allow the program to run 24/7 without  having a user signed in. 

To that end, my current version of the program uses a web browser control (system.windows.forms.webbrowser) to navigate the pages, click the buttons, allow scripts to do their thing, etc.  I cannot figure out a way to do the same without the web browser control, but the web browser control cannot be instantiated in a windows service (because there is no user interface in a web service).

Does anyone have any brilliant ideas on how to get around this?

Thank you very much!

Answers

Hi Andy,

There is a tool which could let you manipulate anything you want on the website. This agile HTML parser builds a read/write DOM and supports plain XPATH or XSLT. It is a .NET code library that allows you to parse "out of the web" HTML files. The parser is very tolerant with "real world" malformed HTML. The object model is very similar to what proposes System.Xml, but for HTML documents (or streams). More information, please check:

You are not telling if you are using a .NET Express edition or not

You are not telling which Framework

You are not realy saying what data you are getting from the web site.

So

I made an example of service that work on any Studio edition (including the Express)

to install it, I supposed that you have at least the Framework2, so you will use something similar to:

    %SystemRoot%\Microsoft.NET\Framework\v2.0.50727\installutil /i C:\Test\MyWindowService\MyWindowService\bin\Release\MyWindowService.exe

In the example, I supposed that you are downloading some file from the site

You will need a reference to Windows.Form for the timer


Imports System.ServiceProcess

Imports System.Configuration.Install

Public Class WindowsService : Inherits ServiceBase

  Private Minute As Integer = 60000

  Private WithEvents Timer As New Timer With {.Interval = 30 * Minute, .Enabled = True}

  Public Sub New()

    Me.ServiceName = "MyService"

    Me.EventLog.Log = "Application"

    Me.CanHandlePowerEvent = True

    Me.CanHandleSessionChangeEvent = True

    Me.CanPauseAndContinue = True

    Me.CanShutdown = True

    Me.CanStop = True

  End Sub


  Private Sub Timer_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer.Tick

    If IO.File.Exists("C:\MyPath.Data") Then IO.File.Delete("C:\MyPath.Data")

    My.Computer.Network.DownloadFile("http://MyURL.com", "C:\MyPath.Data", "MyUserName", "MyPassword")

    'Do Something with the data downloaded

  End Sub

End Class

<Microsoft.VisualBasic.HideModuleName()> _

Module MainModule

  Public TheServiceName As String

  Public Sub main()

    Dim TheServiceApplication As New WindowsService

    TheServiceName = TheServiceApplication.ServiceName

    ServiceBase.Run(TheServiceApplication)

  End Sub

End Module

<System.ComponentModel.RunInstaller(True)> _

Public Class WindowsServiceInstaller : Inherits Installer

  Public Sub New()

    Dim serviceProcessInstaller As ServiceProcessInstaller = New ServiceProcessInstaller()

    Dim serviceInstaller As ServiceInstaller = New ServiceInstaller()

    serviceProcessInstaller.Account = ServiceAccount.LocalSystem

    serviceProcessInstaller.Username = Nothing

    serviceProcessInstaller.Password = Nothing

    serviceInstaller.DisplayName = "My Windows Service"

    serviceInstaller.StartType = ServiceStartMode.Automatic

    serviceInstaller.ServiceName = TheServiceName

    Me.Installers.Add(serviceProcessInstaller)

    Me.Installers.Add(serviceInstaller)

  End Sub

End Class



 Hello Andy,

Thanks for your post.

What do you want to scrape from the page? HttpWebRequest class ans WebClient class may be what you need. More information, please check:

The HttpWebRequest class provides support for the properties and methods defined in WebRequest and for additional properties and methods that enable the user to interact directly with servers using HTTP.

http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx

The WebClient class provides common methods for sending data to or receiving data from any local, intranet, or Internet resource identified by a URI

Have a nice day.

Best regards



Thank you for the reply. Sorry it has taken me so long to respond.  I did not receive any notification that someone had replied!

I am using Visual Studio 2010 Ultimate Edition and the .NET framework 4.0.  Actually, I am upgrading some old code written in VB 6.0, but I can use the latest and greatest thats available.

The application uses a browser control to go to the page, fill in values, click on UI elements, read the HTML that returns, etc.  The purpose of the application is to collection useful information regularily/automatically.

I know how to create a web service, but using the web control in such a service is problematic because the web browser control was meant to be placed on a windows form.  I am not able to create a new instance of it in a project designated as a windows service.



Andy

Thank you for the reply. Sorry it has taken me so long to respond.  I did not receive any notification that someone had replied!

I thought a web request was for web services (retrieving information from them).  I am trying to retreive useful information from a website designed for interaction by a human, such as selecting items from lists and clicking buttons.   I currently use a web browser control to programmatically do what a person would do and get the pages back which in turn get parsed.

Data Mining and Market Research

Online market research attributes to success and growth of many businesses. Online market research in simple terms we can say it is the learning of current and the latest market situations which involve surveys, web and data mining modules. To date research by use of the internet it is very important since it depends on data gathered from internet services and then one can recognize that market research keeps the business successful.

A number of managers in small businesses have a mental deem in that online market research is obligatory to big or larger companies. For true you will understand that whether the businesses is medium, large or small actually need online marketing research and this is a reason why the significance of the process and allegation will approve the targeted and potential clients. In this case Data mining progression is employed to streamline on what targeted and potential clientele needs. Areas where data mining is used:

Preferences. In any given service or product, you will learn what a customer looking for and how your product or service is different from other competitors. By use of Data mining you will be able to determine the customer preferences and you will be able to modify your services and products meet the customer choice.

Buying patterns. What is known and created for purchasing patterns from different customers. A situation can be that customers try to spend a lot on certain products and little on others. But through Data mining it is easy to understand such purchasing patterns and finally plan the appropriate techniques to be used in the marketing.

Prices. To find out whether the company is selling its products to the clients or not prices are the key factors to take into account. One should understand on the right selling price of the products. Web scrapping is easier to find the suitable pricing.

SEO No No! Scraping & Splogging – Content Theft!

Until recently, you could as well as might possibly not have acknowledged how you can perform the earlier mentioned. Even so, the following element could be the really cool element.

Several. Get back to ScrapeBox Add-Ons and also down load your ScrapeBox Blog Analyzer add-on. Open it upwards, and transfer the actual .txt record you merely rescued. Struck start.

ScrapeBox goes through almost every back link you merely scraped and look these phones determine if these are your site that will ScrapeBox presently facilitates placing comments in. If it is, that turns environmentally friendly. If it isn’t, that turns reddish. Soon after it really is concluded, it is possible to “clean” the list insurance agencies the idea remove unsupported websites.

Just what you’re destined to be left with is ALL of the sites the competitor has back-links via, and most importantly, they all are capable of being mentioned in employing ScrapeBox!!

Help save that will “clean” listing with a report, import it this list involving websites you wish to touch upon, and then keep to the exact same steps you’d probably typically follow for you to touch upon websites. Inside of Ten mins you’ll have got all the comps website backlinks (which may be blocked by Public relations if you’d just like) along with you’ll be able to reply to every one of them inside a 20 min (because the list most likely won’t end up being Large).

Desire to force this specific even more?? Obviously you are doing, you’re in BHW

Each step is the same as over with the exception of one tiny issue as well as the addition of an extra step.

Instead of just employing a single foot print inside your first bounty (both from SB’s regular gui after which also the back link checker add-on) you’re likely to be using a A lot of open all of them. Here is what you do to consider this particular to a whole new amount.

Initial, you’re going to pick each of the URLs via AOL, Aol, Ask & Search engines using this footprint:

site:domainyourcompetingwith.org

That will go back ALL the at present found web pages in the area. Remove copy Web addresses along with save that will with a .TXT report.

Now, you’re planning to create the subsequent right in front of each of these URLs:

hyperlink:

Right now follow all of the steps while outlined above. Exactly what this may is actually obtain each of the backlinks to every single site of the rivals web site.

Because Google Back link Checker is simply capable of getting the first 1k Web addresses through Aol (while that’s all Google allows you to view) you could have missed out on a decent amount associated with website inbound links if they had been at night 1st 1k final results. Consequently performing the aforementioned further methods ensures that every brand new web site in the website anyone pay attention to backlinks implies a fresh and other pair of a listing of back-links that is possibly 1k back links long.

Now you understand how to locate, filtration along with take your competitors back links, stop looking at and also move and take action!

Data Mining and Predictive Analysis

Data collection and curing is the core foundation of most businesses. Database building thus is an important function and activity where enterprises invest heavily. With information now available on the Internet and easily obtained, it raises the importance of having professionals who crawl data and offer web scraping services.

Once the data is accessed, though, it is important to filter out the relevant data based on the business need. Although Many DaaS provider convert the unstructured web data into meaningful structured data it is recommended to be internally equipped to use the data to its maximum.

This understanding has given rise to the field of Data Mining. Data Mining is designed to explore large amounts of data in search of consistent patterns and connections between the variables and validate the findings by applying the detected patterns to the new sets of the data. Once these connections are established and understood, the end goal is to be able to predict the possible outcomes using predictive analysis techniques.

Together, both Data Mining and predictive analysis aid in making marketing campaigns more efficient. While predictive analysis helps simulate and understand what may happen, data mining helps identify exciting data patterns and connections.

The process of Data Mining and Predictive analysis consists of 3 steps

Exploration


Once a database is compiled, it needs to be cleaned, analysed and potential connections need to be built. This process involves filtering the relevant data and identifying the possible predictors. Data Exploration also sets a premise for preliminary feature selection to manage number of variables. This data is then prepared for statistical analysis using a wide variety of graphical and statistical parameters. This helps identify the most relevant variables and setups the predictive models to be built.

Data mining process

Validation


Next comes building various models and choosing the most relevant ones. This decision is based on their possible predictive performance and of being able to produce stable results across all the samples. Simple as it sounds, to truly get the results, all possible models must be treated with data to simulate scenarios. The model with most stable statistical feature is validated.

Application


Once the relevant models are finalised, the same is applied to new data to understand and predict the estimated outcomes. Application of data models is an ongoing and complex process since every new dataset needs to be configured in the model.

Data Mining and predictive analysis essentially involves blending statistical methodology where the traditional statistics machine learning and complex algorithms. This greatly increases the need for efficient and skilled data handlers. This could include data analysts and scientists.

See how you can become data scientist here:

Data crunchers use data mining and predictive analysis actively to get an edge in the big data management. Database platforms like Hadoop assist in database management and large-scale distribution. But the costs involved in setting up data centres and big data management capacity are high. Budgets allocated within the enterprise are more project-focussed and analytics budgets are usually limited. Quite often, big data and analytics project fail to launch because of this problem! The other problem is that to run effective predictive models, data requires to be handled by scientists with experience. Finding and setting together a technologically-advanced team is a daunting task most enterprises face outside the tech domain.

Predictive Analysis model

A predictive analysis model is essentially predicting the all possible outcomes from a given set of data. Here are a few steps that can be taken to help build and identify the “ideal” predictive analysis model. These steps more or less mirror the usual statistical methodology of building a test model.

Defining an objective

This is the first and a critical step. Unless the objective is identified and defined there can be no concrete results since there wouldn’t be clarity to compare the final outcome to the expected result. It also helps understand the scope of the project.

Preparing the data


This is more to do with data mining. Historic data used for training the model is scattered across multiple platforms and sources. To compound the problem, data can be unstructured with possible duplicate accounts and missing values! Data quality determines the quality of the model, and thus it becomes imperative that data is healthy and relevant.

Data Sampling

Once mined, Data is essentially split into 2 parts. One set is for training that is used to build the model and the second is the ‘test’ set that is used to verify the accuracy of the final output. This also helps identify and filter the noise component.

Model Building


Sampling cam equally result in a single algorithm or parallel & connected algorithms. In such a case the data goes through multiple testing and a decision is based on the final output.

Execution


Once a model gets finalised, the other teams in the organization need to be involved to build a deployable model and understand its impact on the overall business.

The possibilities with Data mining & Predictive analysis are huge. It also gives a huge room for learning and experimenting. There are several tools available in the industry to aid through all the steps of data mining and predictive analysis. The combination of human expertise and intellect along with the help of the available tools and the overall cooperation within the multiple channels within the organization essentially ensures a stronger grip on the ability to build a solid predictive model.

When used together, predictive analytics and data mining help marketing professionals anticipate and get ready for customer needs, rather than just reacting to them.

How to Build Data Warehouses using Web Scraping

Businesses all over the world are facing an avalanche of information which needs to be collated, organized, analyzed and utilized in an appropriate fashion. Moreover, with each increasing year there is a perceived shortening of the turnaround time for businesses to take decisions based on information they have assimilated. Data Extractors, therefore, have evolved with a more significant role in modern day businesses than just mere collectors or scrapers of unstructured data. They cleanse structure and store contextual data in veritable warehouses, so as to make it available for transformation into useable information as and when the business requires. Data warehouses, therefore, are the curators of information which businesses seek to treasure and to use.

Understanding Data Warehouses

 Traditionally, Data Warehouses have been premised on the concept of getting easy access to readily available data. Modern day usage has helped it to evolve as a rich repository to store current and historical data that can be used to conduct data analysis and generate reports. As it also stores historical data, Data Warehouses are used to generate trending reports to help businesses foresee their prospects. In other words, data warehouses are the modern day crystal balls which businesses zealously pore over to foretell their future in the Industry.

Scraping Web Data for Creating Warehouses

The Web, as we know it, is a rich repository of a whole host of information. However, it is not always easy to access this information for the benefit of our businesses through manual processes. The data extractor tools, therefore, have been built to quickly and easily, scrape, cleanse and structure and store it in Data Warehouses so as to be readily available in a useable format.

Web Scraping tools are variously designed to help both programmers as well as non-programmers to retain their comfort zone while collecting data to create the data warehouses. There are several tools with point and click interfaces that ease out the process considerably. You can simply define the type of data you want and the tool will take care of the rest. Also, most tools such as these are able to store the data in the cloud and therefore do not need to maintain costly hardware or whole teams of developers to manage the repository.

Moreover, as most tools use a browser rendering technology, it helps to simulate the web viewing experience of humans thereby easing the usability aspect among business users facilitating the data extraction and storage process further.

Conclusion

The internet as we know it is stocked with valuable data most of which are not always easy to access. Web Data extraction tools have therefore gained popularity among businesses as they browse, search, navigate simulating your experience of web browsing and finally extract data fields specific to your industry and appropriate to your needs. These are stored in repositories for analysis and generation of reports. Thus evolves the need and utility of Data warehouses. As the process of data collection and organization from unstructured to structured form is automated, there is an assurance of accuracy built into the process which enhances the value and credibility of data warehouses. Web Data scraping is no doubt the value enhancers for Data warehouses in the current scenario.
