According to analysis targets, web mining can be divided into three different types, which are Web usage mining, Web content mining and Web structure mining. Web usage mining[edit] Web usage mining is the process of extracting useful information from server logs e.g. use Web usage mining is the process of finding out what users are looking for on the Internet. Some users might be looking at only textual data, whereas some others might be interested in multimedia data. Web Usage Mining is the application of data mining techniques to discover interesting usage patterns from Web data in order to understand and better serve the needs of Web-based applications.
Web Server Data: The user logs are collected by the Web server. Web structure mining[edit] Web structure mining is the process of using graph theory to analyze the node and connection structure of a web site. 1. 2.
Social engines. Ten Most. The 100 Best, Most Interesting Blogs and Websites of 2012 (Categorized) Editor’s note: 2015’s list of the best, most interesting websites has arrived!
I don’t know about you, but I’m constantly running into so many cool websites I want to remember or recommend to people but I don’t always have time to make a note of them, add them to Evernote, bookmark them in Delicious, etc. So this is a good example of a post I created as a personal (and completely unscientific) resource that other people will probably benefit from as well. Some of these sites are pretty new while others have been around for a while now, but they are all awesome right now in 2012. So whether you are looking for a way to catch up on the latest Internet trends, want to find some exciting new content to load into your favorite news aggregating app or are just bored and need to waste some time online, this list represents hours of potential discovery.

That's the minimum number of AND or OR operators you need in order to write any Boolean function of five variables. Alex Healy and I computed that in April 2010. Until then, I believe no one had ever known that little fact. This post describes how we computed it and how we almost got scooped by Knuth's Volume 4A which considers the problem for AND, OR, and XOR.
A Naive Brute Force Approach Any Boolean function of two variables can be written with at most 3 AND or OR operators: the parity function on two variables X XOR Y is (X AND Y') OR (X' AND Y), where X' denotes “not X.” For three variables, parity is also a hardest function, requiring 9 operators: X XOR Y XOR Z = (X*Z'+X'*Z+Y')*(X*Z+X'*Z'+Y). For four variables, parity is still a hardest function, requiring 15 operators: W XOR X XOR Y XOR Z = (X*Z'+X'*Z+W'*Y+W*Y')*(X*Z+X'*Z'+W*Y+W'*Y'). The sequence so far prompts a few questions. The program I wrote was a mangling of the Floyd-Warshall all-pairs shortest paths algorithm. Indeed. Tracky is a Social Collaboration App That Will Get Tasks Done.
