When it comes to web content extraction, many ways can be done. Now, before we jump into the techniques, let us get the basic idea cleared about the web content extractor.
There is a whole lot of information available on the web which brings the need for a strategy or tool to the forefront for extracting valuable knowledge. and Once you have gathered data with the help of a web content extractor, web content mining comes into the picture.
Web mining is the application of data mining concepts and techniques to the World Wide Web. Web mining is an important technique in data mining. It can be performed in three different ways namely web structure mining, web content mining, and web usage mining.
Web usage mining helps in the collection of web access information for the web pages. Web content mining refers to the scanning and mining of text, graphs, and images of web pages to figure out the relevance of the content to the search query made. Web structure mining is used for identifying the relationship between the web pages linked by information.
Web mining is the technique that automatically discovers the information from the data collected with the help of a web content extractor. The mining process identifies interesting or useful patterns which can be helpful for individuals or businesses. Web mining is the integration of all the information collected by data mining techniques and methods with information collected over the World Wide Web. It can be said that web mining is an effort that draws techniques from diverse filed such as in-information retrieval statistics, natural learning processing, machine learning, and more.
WebDataGuru provides web content extractor to many online retailers and industries alike. So, when you want to get into web content mining, you know where to come.
The web mining process can be classified into three types which are as follows:
Web content mining refers to the extraction of useful information from web documents. It is related to text mining as much of the web content is text-based. Text mining focuses on unstructured texts. Web content mining can be categorized into two types- ones that directly mine the content and others that improve the content search of tools such as search engines. Content mining is useful for the examination of data that is gathered by search engines and web spiders. The technologies used in web content mining are known as NLP i.e. Natural Language Processing and IR i.e. Information Retrieval.
Web structure mining discovers useful information from structure and hyperlinks. The purpose of web structure mining is to generate a structured summary of the web pages and websites. and It is just like using the tree-like structure for analyzing as well as describing XML or HTML.
Web usage mining is the process of identifying browsing patterns via analysis of the navigational behavior of the visitors. It focuses on techniques that can help in predicting user behavior when the user interacts with the web. It makes use of secondary data on the web. and This consists of automatic discovery of user access patterns from the web servers. The process involves three stages namely pre-processing, pattern discovery, and pattern analysis. Web usage mining can be further categorized based on the kind of usage data considered i.e. so Web server data or Application level data.
Structured data extraction is used widely in the web content mining process. It is easy to extract as compared to unstructured data. and There are different approaches to structure data extraction known as wrapper generation.
The first approach is manually writing an extraction program for each website depending on patterns observed from the site. This can be time-consuming and isn’t feasible for a large number of sites.
The second approach is wrapper learning/ induction. In this method, the user manually labels a set of trained pages. Then a learning system generates rules from training pages. so These rules are further applied for extracting target items from the web pages.
A third approach is an automatic approach where the structured data objects on the web are retrieved from the database and displayed on the web pages with fixed templates.
Web pages are generally seen as text documents. It is to be known that the extraction of information from web documents has been studied by researchers. The research is all about text mining, information retrieval, and natural language processing. and At present, the techniques are based on machine learning and natural language processing for learning extraction rules.
Many researchers also make use of common language patterns on the web for finding concepts, the relation among concepts, and named entities.so The patterns can be learned automatically by human users.
In web data mining, classification or clustering is used for eliminating noisy blocks allowing you to produce better results.
Two processes that can help in mining useful information are classification and clustering. Each technique used for classification has its benefits as well as disadvantages. and The choice of the technique depends on the application. The classification techniques can also be considered for the improvement of performance.
It is to be known that web mining is the key to boosting your business on the web. The information gathered from the web content extractor is mined and used for quantifying the success of a marketing campaign for any organization. so Web mining is a web analytics solution that helps organizations in analyzing the effectiveness of specific websites along with understanding consumer behavior and competitor’s strategy efficiently.
One of the most important benefits of information gathered via web mining is that it offers actionable insights into web structure, content, and usage.so Web mining is the need of the hour for any business that is looking forward to growing with the help of information extraction from the web.
