Search Engine

A web search engine  is  a  software which is designed to search information on the World Wide Web (WWW).

The search results are often referred to as search engine results pages (S E R Ps). The information may be a mix of web pages, images, or other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.

Search Engines play a very important role for every website to get its traffic audience. Each and every website owner wants to be in the top page of the search results. And This is done by S E O process. Now the question arises that what is S E O? lets have a brief look on this.

S E O -Search engine optimization is the process of affecting the visibility of a website or a web page in a web search engine’s unpaid results often referred to as ” natural “, ” organic”, or “earned” results. In general the earlier and more frequently a site appears in the search results list. The more visitors it will receive from the search engine’s users. Few of these visitors can then be converted into customers.


  • Getting indexed.

The leading search engines such as Google, Bing and Yahoo use crawlers to find pages for their algorithmic search results. Pages which are linked from other search engine indexed pages do not need to be submitted because they are found automatically.

  • Preventing crawling.

To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain

  • Increasing prominence.

Data Mining

Data mining is the computing process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems.

Data mining involves six common classes of tasks:

  1. Anomaly detection

  2. Association rule learning

  3. Clustering

  4. Classification

  5. Regression

  6. Summarization

It can be referred as an interdisciplinary subfield of computer science. The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use.
It also involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating.
The term is a misnomer, as the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction (mining) of data itself.
You can refer The book Data mining: Practical machine learning tools and techniques with Java (which covers machine learning materials) and was originally to be named just Practical machine learning, The term data mining was only added for marketing reasons.
The actual data mining task is the automatic or semi-automatic analysis of large quantities of data to extract previously unknown, interesting patterns such as groups of data records and dependencies which usually involves using database techniques such as spatial indices. These patterns can then be seen as a kind of summary of the input data, and may be used in further analysis.

What is Web Page

What is Web Page?

A webpage is a document (also refers to a computer file) which is suitable for  World Wide Web and the  web browsers.

Usually written in HTML ,PHP or comparable markup language… Depending the requirement Script of a web page can be any one of the language or combination of few languages.

A web browser is a software which displays a web page on a computer device (Mobile/PC) .  Web browsers coordinate the various web resource elements. For the written web pages, such as style sheets, scripts, and images, to present the web pages.

Typical web pages provide hypertext that includes a navigation bar or a sidebar menu to other web pages via hyperlinks, often referred as page link.
