For this project, we will be using the KNearst Neighbor algorithm.<\/p>\n<p>So, let\u2019s build this system.<\/p>\n<h3>Book Recommendation System<\/h3>\n<p>When selling goods online, most businesses have their own recommendation system. However, almost all websites are not created with the customer in mind; businesses use them to force customers to purchase additional, irrelevant things. An individual user can select fascinating and practical things from a vast selection of products with the aid of a personalized recommendation system (PRS).<\/p>\n<p>Customers now have a wide range of possibilities for products from eCommerce sites because of the expansion of the internet. It can be difficult for customers to locate the ideal products at the ideal moment. Users can find books, news, movies, music, online courses, and research articles using a personalized recommendation system.<\/p>\n<p>Technological advances in areas like the internet of things (IoT), artificial intelligence (AI), quantum computing, etc., ushered in the fourth industrial revolution. The economic boom raises peoples&#8217; purchasing power and their level of living. Due to their busy schedules and the COVID-19 pandemic, physical trips to stores and libraries have significantly decreased in recent years. Instead, e-marketplaces and e-libraries grew to be well-liked gathering spaces.<\/p>\n<p>Users could find their favorite books from a wide selection thanks to e-book reading platforms and online shopping habits. Expert systems enable consumers to quickly and wisely choose among an unparalleled number of options. As a result, recommendation systems emerged to personalize users&#8217; searches and provide the most advantageous outcomes from various possibilities. Amazon first suggested a personalized suggestion system, which helped to increase sales from $9.9 billion to $12.83 billion in 2019 (the second fiscal quarter), which was 29% more than the previous year.<\/p>\n<p>A university library has thousands or millions of books. If readers only have a basic understanding of books, it is difficult to locate the books they require. It is also challenging for the library to utilize these books in paper form to their full potential. How can we make it easier for readers to find the books they want? And how can I use a library&#8217;s books to their fullest potential? These are formidable obstacles for a library.<\/p>\n<p>Some academics have implemented recommender systems for the library. Recommender systems offer users individualized suggestions for goods or services. Collaborative filtering is a method that is frequently employed (CF). CF is a method of forecasting a user&#8217;s preferences based on the preferences of several users. It solely relies on the user&#8217;s prior behavior data, and it has been very successful in a variety of fields, including many large and prosperous websites like Amazon and others.<\/p>\n<p>In order to create a book recommendation system, CF can be employed. In CF, the neighbor-based methods and latent factor models(LFM) are the two primary types. The LFM is a model-based CF approach that builds the data model using knowledge about the observed preferences. In order to deal with sparsity and forecast preferences that are not observed, it is built on the matrix factorization technique. LFM has more extensibility and forecast accuracy. By including biases and implicit feedback, SVD++ improves upon LFM&#8217;s accuracy. It benefits from both explicit and implicit input.<\/p>\n<h3>K-Nearest Neighbor<\/h3>\n<p>The K-Nearest Neighbor classifier compares a given test tuple with a group of training tuples that are comparable to it in order to recognize and classify patterns. One of the easiest techniques for resolving classification issues is the KNearest Neighbor (K-NN) algorithm, which frequently produces results that are competitive with other data mining techniques.<br \/>\n(1) Using similarity or distance to classify recommendations more quickly and accurately for the client.<br \/>\n(2) In order to produce a set of recommendations to the client more quickly, our recommendation engine gathers the clickstream data from the active users and matches it to a specific user&#8217;s group. Typically, the Euclidean distance between the training and test tuples is used by the K-Nearest Neighbor classifier.<\/p>\n<p>A user and book pair (UI, bj) is inputted into the k Nearest Neighbors algorithm, which produces a forecast of the unknown rating for book bj from user UI. There are two distinct approaches to applying the k Nearest Neighbors algorithm to the goal of predicting book ratings. One is based on users, and the other is based on items. Users who have rated book bj are all examined by user-based kNN, and it identifies the k co-rated users who are most similar to UI. The ratings of these k users, known as the k nearest neighbors of ui, are used to forecast UI&#8217;s rating of book bj on the basis that similar users tend to rate books similarly.<\/p>\n<p>In contrast, the item-based kNN first identifies the set of all the books that user UI has rated and then selects k books from this set that are most comparable to book bj (the k nearest neighbors, in this case, are these k most similar books). The ratings given by the user to these k closest neighbors are then utilized to forecast the user&#8217;s rating of the book bj. The item-based KNN&#8217;s underlying premise is that users have a tendency to evaluate comparable books similarly. Since the relationships between books are more static than the relationships between users, we chose to employ the item-based kNN.<\/p>\n<h3>Project Prerequisites<\/h3>\n<p>The requirement for this project is Python 3.6 on your computer. I have used Jupyter notebook for this project. You can use whatever you want.<br \/>\nThe required modules for this project are &#8211;<\/p>\n<ol>\n<li>Numpy(1.22.4) &#8211; pip install numpy<\/li>\n<li>Sklearn(1.1.1) &#8211; pip install sklearn<\/li>\n<li>Pandas(1.5.0) &#8211; pip install pandas<\/li>\n<\/ol>\n<p>That\u2019s all we need for our project.<\/p>\n<h3>Book Recommendation System<\/h3>\n<p>We provide the dataset and source for the book recommendation system project. The csv file contains the name of different books and the rating of every book. Please download book recommendation system project and data from the following link: <a href=\"https:\/\/drive.google.com\/file\/d\/10LKhRLJayk5Mj5sWogr3IXECbnPGgM88\/view?usp=drive_link\"><strong>Book Recommendation Project<\/strong><\/a><\/p>\n<h3>Steps to Implement<\/h3>\n<p>1. Import the modules and all the libraries we would require in this project. We will use Numpy, Pandas, and Seaborn in this project. We are also going to use sklearn in this project. So we have imported all the modules for that. We then read our dataset file and store it in a variable. We also imported sklearn because it contains the model we will use in the book recommendation system project.<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\">import numpy as np#importing the numpy library\r\nimport pandas as pd#importing the pandas library\r\nimport seaborn as sns#importing the seaborn library\r\nimport matplotlib.pyplot as plt#importing the matplot library\r\n \r\ndataframe=pd.read_csv('dataset.csv', error_bad_lines=False)#reading the dataset\r\ndf=df.drop(['Unnamed: 12'], axis=1)#dropping the unnamed column\r\ndf.head()#printing the dataframe\r\n \r\nfrom sklearn.ensemble import RandomForestClassifier#importing the Random Forest classifier\r\n \r\nfrom sklearn.model_selection import train_test_split#importing the Random Forest classifier\r\nfrom sklearn.preprocessing import StandardScaler#importing the Standard Scalar\r\nfrom sklearn.metrics import accuracy_score, f1_score,confusion_matrix,classification_report#importing the confusion matrix and classification report\r\n<\/pre>\n<p>2. Here, we are doing some pre-processing of the data. We are taking the top ten books according to ratings and then we are sorting it in descending order. We are also sorting our dataset according to the authors&#8217; count and the average rating and we are storing it in the dataset.<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\">top_ten_ratings=dataframe[dataframe['ratings_count']&gt;1000000]#getting the rows with most ratings\r\ntop_ten_ratings=top_ten_ratings.sort_values(by='ratings_count', ascending=False).head(10)#priting the sorted data\r\n \r\ndataframe=dataframe.sort_values('average_rating').reset_index()#sorting the dataframe according to average rating\r\ndataframe=dataframe.iloc[4:]\r\ndataframe.average_rating=dataframe.average_rating.astype(float)#changing the type to float\r\ndataframe=dataframe.iloc[4:]\r\ndataframe.num_pages=dataframe.num_pages.astype(float)#changing the type to float\r\n<\/pre>\n<p>3. Here we are copying our dataset into another variable we are extracting just the important features of the dataset. We take the rating and the languages and then we are concatenating both of these features and then we are storing it in another variable. At the end, we plot a bar chart of top 10 authors with most selling books.<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\"> \r\ndataframe2=dataframe.copy()\r\ndataframe2.loc[(dataframe2['average_rating']&gt;=0)&amp;(dataframe2['average_rating']&lt;=1),'rating between']=\"between 0 and 1\"#getting the rows with average rating between 0 and 1\r\ndataframe2.loc[(dataframe2['average_rating']&gt;1)&amp;(dataframe2['average_rating']&lt;=2),'rating between']=\"between 1 and 2\"#getting the rows with average rating between 1 and 2\r\ndataframe2.loc[(dataframe2['average_rating']&gt;2)&amp;(dataframe2['average_rating']&lt;=3),'rating between']=\"between 2 and 3\"#getting the rows with average rating between 2 and 3\r\ndataframe2.loc[(dataframe2['average_rating']&gt;3)&amp;(dataframe2['average_rating']&lt;=4),'rating between']=\"between 3 and 4\"#getting the rows with average rating between 3 and 4\r\ndataframe2.loc[(dataframe2['average_rating']&gt;4)&amp;(dataframe2['average_rating']&lt;=5),'rating between']=\"between 4 and 5\"#getting the rows with average rating between 4 and 5\r\ndataframe2.sort_values('average_rating')#sorting the dataframe\r\n \r\ndataframe_rating=pd.get_dummies(dataframe2['rating between'])\r\ndataframe_language=pd.get_dummies(dataframe2['language_code'])\r\nfeature_dataframe=pd.concat([dataframe_rating, dataframe_language, dataframe2['average_rating'], dataframe2['ratings_count']], axis=1)\r\n \r\n<\/pre>\n<p>4. Here we are creating our Random Forest Classifier. First, we are creating our testing and training dataset. For this, we are using the train_test_split function of the sklearn. Then we import our NearestNeighbors model, and then we pass our testing dataset into it. We are using the \u2018ball_tree\u2019 algorithm in our model. Then we are creating a function for bookRecom which will take the name of the book and then it will give us the suggestion for that book.<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\">from sklearn.preprocessing import MinMaxScaler#importing the min max scalar\r\n \r\nminmax=MinMaxScaler()#creating instance of min max scalar\r\n \r\nfeature=minmax.fit_transform(feature) #fitting the feature to instance\r\nfrom sklearn.model_selection import train_test_split#importing the library for splitting the dataset\r\n \r\nmodel=neighbors.NearestNeighbors(n_neighbors=8, algorithm='ball_tree')#creating the model\r\n \r\nmodel.fit(feature) #fitting the model\r\n \r\ndist, book_id=model.kneighbors(feature)#getting the id of the book\r\ndef recommend_book(name):#defining function for book recom\r\n    list=[]#creating a book list\r\n    id=dataframe2[dataframe2['title']==name].index\r\n    id=id[0]\r\n    for books in book_id[id]:\r\n        list.append(dataframe2.loc[books].title)\r\n    return list\r\n \r\nresult=recommend_book('Warrior of the Light')#finding a book suggestion\r\nresult#printing the result\r\n \r\n \r\n<\/pre>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2022\/12\/book-recommendation-system-output.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-111244\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2022\/12\/book-recommendation-system-output.png\" alt=\"book recommendation system output\" width=\"1920\" height=\"1080\" \/><\/a><\/p>\n<h3>Summary<\/h3>\n<p>A book recommendation system suggests books to users based on their interests, past reads, and ratings.
