Document 3 the,dish,ran,away,with,the,spoon The rationale behind developing a forward index is that as documents are parsed, it is better to immediately store the words per document. The delineation enables asynchronous system processing, which partially circumvents the inverted index update bottleneck. The forward index is essentially a list of pairs consisting of a document and a word, collated by the document. Converting the forward index to an inverted index is only a matter of sorting the pairs by the words.
Search engines can provide uncanny results tailored to your very person. How they do it may leave you at risk, read on to find out how to prevent data collection.
They are the road map to the Internet and after your router and ISP are the most important feature of web surfing.
A general sort of knowledge, a simple word or phrase, is all it takes. The Internet would certainly function without search engines as we know them today but it would be a lot different.
Along with the ability to find and direct you to the information and websites that you want search engines provide many other services. One of them being advertising and more specific a targeted kind of advertising that delivers content directly to the demographic most likely to be interested.

Pretty amazing if you think about but also pretty scary when you consider how they do it. What is a search engine?
While the specifics vary from engine to engine in general, a search engine is a complex algorithm or suite of algorithms, computer software, that scours the Internet looking for information and websites based on a preset criteria, specifically the key word or phrase.
Other information that may be included in the search criteria are demographic data about the person conducting the search which is used to filter results. Top data collecting search engines can fine tune results to the point of delivering age, gender and personal interest specific ads directly to your computer screen.
One of those steps is indexing. Indexing is when the engines use what are called spiders, programs whose job is to crawl the web and determine what content is located where, to develop a list of all the websites categorized by content. Within the categories the websites are ranked.
The websites with the highest quality content, the content that is the most relevant to search queries with the longest lasting value get the higher ranks. When you conduct a search the engine goes to the index and finds the websites that best match your query. Only the highest ranked content will be displayed on the first page and above the fold, that means on the screen at the top of the page and seen without having to scroll down, which are the spots that receive the majority of all clicks.
Search engines, advertising and the quest to be 1 has led to the rise of an entire industry, Content Marketing and SEO. This industry relies on search ranking to generate clicks and website traffic for the purpose of promoting or selling products or ad space.
Another method of filtering search results, and the one of most concern to us as Internet users, is data mining.
Data mining is a specialization within computer science that seeks to derive information from large sets of data. The field is interdisciplinary including artificial intelligence, machine learning, statistics and database systems. The term itself is a little misleading, suggesting the collection of data when in fact it is the derivation of information from that data that it refers to.
While data collection and the use of that data by search engines falls under the umbrella of data mining to say that data mining is simply collecting and processing large amounts of data is like saying 18 year old Scotch is just whiskey.
Three sub-fields or types of data mining are: Search engine data mining may use cluster analysis to determine groups of interest, anomaly detection to fine tune personal results and associations to derive suggestions tailored to personal interests.Contrary to assertions that people “don’t care” about privacy in the digital age, this survey suggests that Americans hold a range of strong views about the importance of control over their personal information and freedom from surveillance in daily life.

Google’s unstoppable data collection machine. so the only data being mined in that app is the same as what is being mined in the search engine: word popularity and ad serving/clicks. (and Google isn’t one) access to my personal information.
I couldn’t even give any feedback to Goggle because the only way to contact them seems to. People search services provide the general public with a dangerous amount of personal information about you. Here's how to opt-out of most -- for now.
My system doesn't do this to your email when you send me a message. I pay a web-hosting company that keeps my email on a server that isn't optimized for data collection .
