Abstract—The technique of Collaborative Filtering is especially successful in generating personalized recommendations. Collaborative Filtering is quickly becoming a popular technique for reducing information overload, often as a technique to complement content based information filtering. More than a decade of research has resulted in numerous algorithms, although no comparison of the different strategies has been made. In fact, a universally accepted way of evaluating a Collaborative Filtering algorithm does not exist yet. In this survey, we explain different techniques found in the literature, and we study the characteristics of each one, highlighting their principal strengths and weaknesses. This Paper Present a new user similarity model to improve the recommendation performance to calculate the similarity of each user. The model not only consider the local context information of user rating but also the global preferences of user behavior.

I. INTRODUCTION
The Internet, with hundreds of millions of pages worldwide, has become the greatest source of information that has ever existed. In
Utilizing the internet to search for information is always quick and painless. In a matter of seconds, the information needed is at your fingertips. The internet along with its speed cuts down time that can be utilized
Ever since the beginning of the human race, people have been innovating and inventing, finding new and better ways to do old things. Today, the proudest achievement of human ingenuity is the internet. With it, all of humanity is connected, to both each other, and all the information they could ever need about anything. Most are welcoming this new wave of available information, especially as it becomes easier to navigate with the help of growing search engines such as Google. However, some are starting to recognize cons to the new system in place, claiming that instantly available information is detrimental to human thought.
The internet has changed our way of thinking and processing information modernly
The internet has affected the way we learn and retrieve information by allow us to not only expand our mind beyond the imaginable but it also helps us retain useful information we might not have known of before using the internet. The internet is another form of technology that human’s
Never has a communications system played so many roles in our lives--or exerted such broad influence over our thoughts--as the Internet does today.
Internet, or the net, as we all know, is a vast source of knowledge for
Because of the increase in the use of the Internet, this information media has become
The internet is a place where anyone can go to share and communicate their ideas. Whether I had questions about what a song meant, what type of gift my seven year old cousin would like, what the opinions of the Israeli-Palestinian conflict were, or what a personal statement should look like, there was never a lack of Google results, each backed up by a person’s thoughts and interpretations.
Friendship is not simply a "relationship", knowing someone, conversing with that person, or dealing with that person in business, school, or in casual acquaintance. True friendship is not just a "relationship", but self-sacrificing love. A friend is also one who supports, sympathizes, and is a person in whom you can confide. There are unique qualities that a person must have to be considered a friend.
The internet which was once just a little puddle, now, have become an ocean; an ocean of knowledge. It is like a magical crystal ball which has an answer for every
There are a lot of important things in life. However, one of the most important things for people to survive in this world is friendship. Without friendship, people can die of loneliness. What do you think about your friends? Do you like your friends? There are a lot of different types of friends. There are friends that I like and some friends with whom I do not get along. Friends with positive characteristics such as reliable, trustworthy and faithful whom I usually get along with are the one that tend to have more friends and the negative one whom I usually not get along with tend to be alone. However, friends with negative characteristic can also give us some good examples of seeing double sides of something, like, a character can be
All of the known recommendation techniques have strengths and weaknesses, and many researchers have chosen to combine techniques in different ways. Hybridization can alleviate some of the problems associated with other recommendation techniques. This system combines different recommender systems to improve information retrieval and gain better performance with fewer of the drawbacks of any individual one and also it can avoid the major disadvantages of other methods. The combination can be done using several alternatives, for example: weighted, switching, mixed, feature combination or augmentation or cascading. Meta techniques avoid the problem of sparsity by compressing ratings over many examples into a model, which can be more easily compared across users. Weighted, Mixed, Switching and Feature Combination. With these hybrids, it does not make sense to talk about the order in which the techniques are applied .The main shortcoming of hybrid methods, however, is increased implementation complexity and expense [14]. Table 10 proposes an overview of hybrid Recommender systems and its
Since the invention of the world wide web in 1989 by Tim Berners-Lee, the global spread of information has become increasingly easy, as more resources become available online. The internet can be a useful tool in research and a great way to accumulate valuable information and knowledge, and can be a medium used to spark intelligent and meaningful discussions, but only if used correctly. Poor navigation of the surplus of content available online can lead to a sinkhole of inaccurate and, frankly, bullshit sources. Attempts at academic communication via online sources can devolve into echo rooms or mindless, childish retorts.
The Internet changed our life enormously, there is no doubt about that. There are many advantages of the Internet that show you the importance of this new medium. What I want
Now the Internet has become a great electronic gateway that provides instant access to global news and information. The databases, documents, files, and programs that are ¡°sitting¡± on Internet computers contain a tremendous amount of information. You can search for and find up-to-the-minute stock market activity, weather reports, music, recipe; you can make
