In technical terms, data scraping is a method of collecting data from a website through specific software. These software programs or web scrapers give the website owners the impression of human web surfing and extract a big volume of data, which is usually difficult for any user visitor to access manually. The apps simulate human exploration of online data by embedding web browsers, or implementing HTTP to fulfill the cause of data extractors.
Relation with data mining
Usually, data mining refers to analyzing data from varied perspectives and transforming it to meaningful information that could help in boosting sales or mitigating financial risks in a business. As for web scraping, it involves extraction of analytical data from the web. At present, web scrapping comprises major source of data extraction carried out by data miners. This is because almost everything is now available online and for any data miner, this resource is no less than a gold mine.
The web scraping process
In this data scraping method, the experts look out for tricks to format the URLs into pages that include the usable information. The web scrapers then parse the DOM tree to extract data from the website. In simple language, the web scrapers process the semi-structured or unstructured dat...

...nethical web scrapers deter to steal data from websites. Hence, the web owners themselves need to be alert enough not to fall prey to such fraudulent activities. Indeed, it is your data and you won 't like it to get compromised at any cost. Just like there are many web scraping tools available online, you can also opt for applications that offer protection against web data extraction as a fruitful remedy. These software safeguard your website content from hacking attacks such as bots, denial of service, brute force, session opening and transaction anomalies, and more.
Summary: Technology has two facets - good and bad. It depends on us which one to adopt; the same holds in the case of web scraping as well. We should make sure to use this innovation for the benefit of society and not to steal away some one 's creativity, which is indeed unethical and at times, illegal

- ... Rushing to analyse usage data without a proper preprocessing method will lead to poor results or even to failure. This was the case for some of the first WUM tools that were designed to directly extract relationship rules or sequential patterns from the list of Web resources logged for one IP address. Without properly cleaning, transforming and structuring the data prior to the analysis, one cannot expect to find meaningful knowledge. In a KDD process, the preprocessing step represents at least 60% of the entire process for about two thirds of the Data Mining experts responding to the survey ....

- This paper introduces an effective method for query adaptive image retrieval using low-level feature extraction and hashing method. The low-level feature primarily constitute color, shape and texture features. For color feature extraction color moments, color Histogram and color correlogram method were implemented and for texture feature extraction used wavelet moment method. Hashing methods is used to embed high-dimensional image features into Hamming space, where search can be performed in real-time based on Hamming distance of compact hash codes....
