Literature Review Title of the paper Tanya V Yadalam, Vaishnavi M Gowda, Vanditha Shiva Kumar, Disha Girish “Career Recommendation Systems using Content based Filtering”Proceedings of the Fifth International Conference on Communication and Electronics Systems (ICCES 2020) Area of work Career Recommendation for registered computer stream students Dataset Dataset contains 17 columns and 20000 entries Methodology/Strategy Recommendation takes a form based input from the user and recommends an accurate and apt career. It recommends three best career options. Career prediction is based on the data filled by the user and perform cosine similarity on that. By applying cosine similarity function, get the similarity between previous user preference and the available jobs and finally get the top recommended jobs according to the score of the similarity.The aim is to implement a feedback and a comment and perform NLP on the given feedback and determine whether it’s a positive, negative or neutral comment to provide better results to the students using the recommender system. Algorithm NLP, Cosine Similarity,Content Based Filtering Result/Accuracy Recommend top three jobs by applying cosine similarity. NLP determine whether the comment or feedback is positive, negative or neutral. Advantages Introduce features of security, reliability and transparency. Recommend 3 top jobs. Can give feedbacks and comments. Limitations It is mainly for Engineering students. No data Encryption mechanism. Future Proposal In future it can be developed for other branches such as business, arts. System can be implemented using collaborative approach.

Paper 2 Title of the paper Vignesh S, Shivani Priyanka C, Shree Manju H, Mythili K “An Intelligent Career Guidance System using Machine Learning “. 2021 7th International Conference on Advanced Computing & Communication Systems (ICACCS) Area of work Engineering department prediction for students after plustwo. Dataset The dataset used for the machine learning model is developed manually. In the dataset, there are five different target labels available each representing a specific department. The dataset contains more than 500 rows which means 500 unique values with several features and target variables. There are seven different features available on the dataset. Methodology/Strategy The framework totally consists of three modules where the whole process take place. First module is skill set assessment module. The second module is the prediction module where with the help of the scores obtained by the candidate the prediction takes place. The third and final module is the result analysis module. In this module a detailed analysis of the candidate’s performance will be represented in various formats Algorithm KNN, SVM, Naïve Bayes, K-Means Clustering Result/Accuracy KNN Accuracy: 0.9410 SVM: 0.8632 Naïve Bayes: 0.8714 Advantages Lower the chances of selecting a department by a candidate where the candidate has higher chance of failure rate. Limitations The skill set analysis need not be with exact knowledge of students. The system is for plustwo students and they have only knowledge within their academics. Future Proposal In the near future the framework’s accuracy rate will be enhanced and additional features can be used for recommending a suitable department and also the outliers of the framework will be removed gradually.

Supported by the An-Najah National University, Palestine, Research Project, under grant ANNU-1920-Sc004. Published on 2020. Area of work Guidance system for high school students in Palestinian community to choose engineering discipline. Dataset The dataset is mainly collected from research survey and stored in database and analysed to create an association between personality types and engineering disciplines in Palestine. The MBTI personality test consists of 21 questions randomly chosen from a dataset of 70 questions. Methodology/Strategy There are 4 main phases: Obtaining student’s personal information including gender, high school grades in STEM courses, and a list of extra-curricular interests. Determining student’s personality type based on a self-administered personality test. Processing input data to construct a personal and academic profile for each student. Build a fuzzy recommender system to provide students with personalized and user-specific ranking of engineering disciplines. Algorithm Fuzzy Logic Result/Accuracy The output of the PCRS application is a bar plot to show the suitability rates of engineering disciplines after applying the fuzzy logic of the system. Advantages Helpful for high school students in developing countries where educational and professional guidance in schools is limited. The bar plot representation provides the user with clear results in a simple way. User can be compare the suitability rates of engineering disciplines. Limitations Time consuming because for each student corresponding processed data of a specific engineering discipline is entered into fuzzy logic and the fuzzy logic determine a personalized rate for it. It should be repeater for all seven engineering disciplines considered in PCRS. Future Proposal In the future, PCRS can be extended to consider more university departments and disciplines other than engineering. The recommendation can be enhanced to consider social-economic factors such as employment rates, economical situation and parent’s background specially in developing countries such as Palestine
- 7. Dataset • Dataset contains 20000 records • Students have to answer 24 questions related to their ability in academics , personality, coding • These 24 questions are feature list • Suggested job role is the class label
- 11. Algorithms • DecisionTree: Classification technique used to classify records in pictorial format • Attribute Selection Measures: Gini Index (a cost function used to evaluate splits in the dataset. It is calculated by subtracting the sum of the squared probabilities of each class from one.), Entropy(measure of the randomness in the information being processed)
- 12. • XG Boost: It works on gradient boosting algorithm • Gradient boosting algorithm works on the basic principle gradient descent.This model is built using tree-based learners(Decision Trees) • XGradient boosting Algorithm: • Final prediction=Base value(the starting prediction from basic decision tree)+LR*w1+LR*w2+..+LR*wn • Where LR= learning rate=eta • w1=residual predicted value by 1st residual model • wn=residual predicted value by nth residual model • Xgboost is different from other gradient boost is because of its tuning parameters • The main tuning parameters are 1)regularisation parameter(Lambda) • 2)threshold that defines auto pruning (Gamma) • 3)Learning rate(eta)
- 13. • SVM: Perform classification by finding the best hyperplane that classifies datapoints in a best way. • Searching for linear optimal separating hyperplane( decision boundary) • Find hyperplane using support vectors and margins • Training tuples that fall on hyperplane are support vectors • Farther a hyperplane from datapoint, larger its margin- optimal hyperplane • Kernel, gamma, c( regularization parameter), random_state
- 15. Feature Selection techniques • Chi SquaredTest: Quantifies the independence of pairs of categorical variables.
- 17. • Data collection: Find an appropriate dataset with appropriate parameters like academic scores, specialization programs, analytic capabilities, personal details like hobbies, workshops, certifications, books interested, etc. • Data Pre-processing: Make the acquired data set in an organized format. Cleaning the null values, invalid data values, and unwanted data. • OneHot Encoding: Applying techniques for converting categorical values in the data into a numerical or ordinal format so that they can be provided to machine learning algorithms.
- 18. Feasibility Analysis • Technical Feasibility: The application is technically feasible because all the technical resources required for the development and working of the application is easily available and reliable. The codes are written in Google Colab, therefore all the libraries will be available, no need to install or import each of those. • Economic Feasibility: The code is working on Google Colab .So the colab consumes an amount of internet. The development of the system will not need a huge amount of money. It will be economically feasible. • Operational Feasibility:Since the code iswritten on Google Colab, no need for worrying about importing or installing the libraries required. There is no need of skill for a new user to open this application and use it
