1. INTRODUCTION

   The rapid pace at which technology is improving and the ever-changing nature of the global job market have dramatically changed the way individuals plan and advance their professional career paths. In the past, career planning and advancement were often done using conventional means such as manual counseling or general advice that may not be applicable in todays fast- changing job market. Today, students and professionals often find it difficult to plan their career paths that meet their skills and career interests in the ever-changing job market. In the last few years, advances in artificial intelligence and data-driven decision- making have created new opportunities in career planning and trajectory prediction.Career trajectory is defined as the career path or advancement that an individual undertakes in their professional career path or career development. Understanding and predicting an individuals career trajectory can help them make informed decisions about their career paths and opportunities. With the increased availability of digital professional profiles or resumes, online job market information, and academic records, large amounts of career-related information can be obtained and analyzed to provide insights into career trajectories.

2. PROBLEM STATEMENT

   It is a complex activity that includes assessing an individuals interests, abilities, educational background, and employment opportunities. However, it is a big challenge for many students and professionals to determine their potential careers because of a lack of accurate information and guidance. Usually, in conventional ways of career guidance, decisions are made through subjective judgment and aptitude tests, which do not reflect the current state of a rapidly evolving job market.One of the biggest challenges in career development is a lack of data-driven insights into the patterns of career growth. Usually, people rely on limited information, their interests, and opinions of others in making decisions regarding their potential careers.Another big challenge in career development is the evolving nature of job roles in the current scenario because of technological advancements. New job roles are being introduced, and some existing job roles are becoming redundant. It is a big challenge for students and professionals to determine the potential of a particular skill in the future because of this constant change in job roles.

3. LITERATURE SURVEY

   Recent advancements in intelligent data analytics have significantly improved the ability to analyze career patterns and workforce trends. The use of predictive models and data-driven methods has enabled researchers to explore new ways of guiding individuals in career planning and professional development. Studies in fields such as Artificial Intelligence and Machine Learning have demonstrated the potential of computational models in predicting career progression based on historical data and skill

   analysis.Several researchers have investigated the use of machine learning algorithms to analyze professional profiles and job transition patterns. Early studies focused on using statistical techniques to examine employment data and identify trends in career mobility. These approaches primarily relied on regression models and clustering techniques to understand relationships between education, skills, and job roles. Although these methods provided useful insights, they lacked the ability to capture complex patterns in large datasets.

      The high-level architecture of the proposed system includes various interconnected components, and the overall objective of the proposed system is to achieve the goal of career trajectory prediction and recommendation. Each component of the proposed system has specific functionalities to achieve the overall goal.The first component of the proposed system is the data collection module, which collects information about the user from various sources. This includes information about the user, educational qualifications, skills, certifications, work experience, and other interests.After the collection of data, the data preprocessing module processes the data collected by the data collection module. Various functionalities of the data preprocessing module are data cleaning, normalization, feature extraction, and transformation. It converts the unstructured data collected from the resume and other sources into a structured format to process the data and prepare it for the machine learning model to predict the desired outcome and solve the problem.

5. AI MODEL DESIGN

   The proposed Career Trajectory Preiction System utilizes the Artificial Intelligence (AI) model as the core component. The main goal of the AI model is to process the user data and provide accurate career progression predictions. The AI model design utilizes various machine learning components, data preprocessing mechanisms, and predictive analytics to provide accurate career trajectory predictions.

   1. Data Collection and Feature Extraction

      The proposed AI model depends on the quality of the input data to provide accurate career trajectory predictions. The proposed system collects various types of data from different aspects of the user's professional profile. These data types include academic qualifications, technical skills, soft skills, Furthermore, the proposed system utilizes external data sets to provide accurate career trajectory predictions.

   2. Data Preprocessing

      Before training the AI model, the data that has been collected goes through a series of preprocessing steps to ensure accuracy and reliability. This includes cleaning the data, normalizing the data, and encoding the data. Cleaning the data involves the removal of incomplete or duplicate data. This ensures that the data does not contain any inconsistencies. During the cleaning process, the missing values in the data are either removed or replaced with the average value. Normalization of the data ensures that the numerical data, such as years of experience and skill rating, does not cause any bias to the learning model. Variables such as job roles, industries, and skill categories are also normalized to numerical values through the encoding process. This ensures that the machine learning model can understand the non-numerical data.

   3. Career Path Prediction

      Once the model has been trained, it can make predictions on the users career path. The prediction process takes the users profile as input and compares it with the historical patterns of careers that the user may undertake.The system predicts the potential future careers that the user may attain over time based on their current skill set and experience. In addition to predicting the users current career path, the model can also make predictions over a period of 5 to 10 years. This allows the user to get a sense of their potential career path and plan their strategy accordingly.

   4. Model Evaluation

      To guarantee the reliability of the predictions made by the AI model, its performance is evaluated using different parameters like accuracy, precision, recall, and F1 score. This is done by splitting the data into training and testing sets.Cross-validation may also be used to prevent overtraining of the model and enhance its ability to generalize. Continuous retraining of the model using new information from the job market will keep the model relevant and aligned with the changing needs of the industry.

6. DATA SOURCES & DATASET DESCRIPTION

   1. Dataset Description
