Collaborative filtering is hard to find similar users due to suffering from data sparsity,cold-start problems,resulting in the problem of recommendation accuracy and reliability to some extend.Based on ontology and semantic Web,this paper aimed to alleviate these problems in terms of finding more sim...
Online Communities: Niche communities and interest-based platforms facilitate the sharing of content among like-minded individuals. Collaborative Projects: Platforms such as GitHub and GitLab enable developers to collaborate on code and open-source projects, contributing to a collective pool of content. ...
Collaborative filtering is based on the assumption that people who agreed in the past will agree in the future, and that they will like similar kinds of items as they liked in the past. The system generates recommendations using only information about rating profiles for different users or items...

we present a new approach, known as user-centered collaborative location and activity filtering (UCLAF), to pull many users’ data together and apply collaborative filtering to find like-minded users and like-patterned activities at different locations. We model the userlocation...
User-based and Item-based Collaborative Filtering algorithms written in Python Develop enviroment Language: Python3 IDE: Eclipse PyDev Prerequisite libraries: Numpy Specification of user-based method If you use a built-up model, the recommender system considers only the nearest neighbors existing in th...
The concept of recommendation algorithms can be classified as collaborative or content-based filtering. Collaborative filtering is a method of predicting users’ preferences based on other users’ preference data. It assumes that users with similar preferences, in general, will have similar preferences ...
View detailed information about the capacity of monitored resources in the web-based GUI. You can view capacity information for storage systems, servers, hypervisors and their internal resources, such as volumes, pools, disks, and virtual machines. For example, you can view the total amount of ...
Collaborative filtering [14], one of the most common approaches, is based on similarity between users. Typically, user similarity is calculated based on input of users by rating a set of items in the system. Due to the overhead of providing such feedback, leveraging implicit interest ...
