David-Igwe/Web-based-Smart-Education-System

This project is an web-based smart education system that uses one of three recommendation algorithms to suggest educational content to users. It's built for the Department of Computer Science, University of Benin, Nigeria. # Web-based Smart Education System This project is a web application predicated upon the power of three kinds of recommendation algorithms (collaborative-filtering recommendation algorithm, content-based recommendation algorithm, and the hybrid recommendation algorithm). By default, the hybrid recommendation algorithm (which is a combination of the previous two) is used, but in the app.js file, the code for the remaining two are commented out. ```javascript app.get('/', catchAsync(async (req, res) => { let recommendedTopics = []; // COLLABORATIVE FILTERING // if(req.user){ // const similarUsers = await collaborative.getSimilarUsers(req.user._id, 3); // const topics = await collaborative.recommendTopics(req.user, similarUsers); // recommendedTopics = await Topic.find({_id: {$in : topics.map(topic => topic.topicId)}}).populate('course'); // shuffleArray(recommendedTopics); // } //CONTENT-BASED FILTERING // if(req.user){ // const topics = await contentBased.recommendTopics(req.user); // recommendedTopics = await Topic.find({_id: {$in : topics}}).populate('course'); // } //HYBRID if(req.user){ const similarUsers = await collaborative.getSimilarUsers(req.user._id, 3); const topics = await collaborative.recommendTopics(req.user, similarUsers); const collaborativeTopics = topics.map(topic => topic.topicId); const contentBasedTopics = await contentBased.recommendTopics(req.user); hybridTopics = mergeArrays(collaborativeTopics, contentBasedTopics); shuffleArray(hybridTopics); hybridTopics = hybridTopics.slice(0, 4); recommendedTopics = await Topic.find({_id: {$in : hybridTopics}}).populate('course') } const courses = await Course.find({}); res.render('index', { courses, recommendedTopics }); })); ``` One can easily comment out the hybrid section and un-comment any one you wish to use. > [!CAUTION] > Do not use more than one algorithm at the same time ## Recommendation Algorithms For more on recommendation algorithms, click here
