    Developing predictive models through data mining is a multifaceted process that involves extracting valuable insights and patterns from vast datasets to make informed predictions about future trends or outcomes. At its core, data mining encompasses various techniques and methodologies aimed at uncovering hidden patterns and relationships within data. The journey begins with data collection, where a diverse range of information is amassed from various sources. This raw data then undergoes preprocessing, involving cleaning, integration, normalization, and feature selection, to ensure its suitability for analysis. The selected features may include numerical, textual, or categorical data, each requiring specific transformations. Machine learning algorithms are then employed to build predictive models based on historical data patterns, allowing the model to learn and generalize from past experiences. Supervised learning approaches, such as regression and classification, are common for predictive modeling, while unsupervised learning techniques, like clustering, can reveal hidden structures within the data. The model's performance is assessed through rigorous evaluation metrics, and iterative refinement may be performed to enhance accuracy. Cross-validation techniques are often employed to assess the model's robustness and generalizability. Additionally, ensembling methods, combining multiple models, can further improve predictive accuracy. Interpretability is crucial, and efforts are made to comprehend and explain the model's decision-making processes, especially in fields where transparency is essential. The development of predictive models through data mining finds applications across diverse domains, including finance, healthcare, marketing, and more. Ultimately, this process empowers decision-makers with valuable insights, enabling them to anticipate future trends, mitigate risks, and make informed decisions based on the patterns extracted from the wealth of available data.

    With the evolution of human computing, a lot of data gets generated every day and due to the humongous variety of the data, it becomes difficult to organize them in such a manner that it provides significant information regarding a specific context. To retrieve information from a collected set of data, an automated system model is required that holds the information regarding the contexts that are evaluated from the dataset. The automated system can be termed as data processing architecture. Contextual sense provides significance to the seeker from any data processing architecture. A data processing architecture is made up of two elements namely the dataset itself and the processing rules. For example, consider a sense of "hungry" and is defined by the total number of chapattis a human eats in a meal. So the rule set could be, "If the object consumes less than or equal to 5 chapattis Outcome is "hungry" else "not hungry". The rules are dependent upon the type of membership function values that are provided to the object. As briefed earlier, Context is the relevant information specific for a particular user. Context Mining is the process to extract the information with respect to a particular context. context is the origin of the demanded information and due to increasing data complexity in terms of volume, variety, and modularity, it becomes almost impossible to perform the contextual analysis manually. Hence, an automated system is required that analyses the asked content based on the stored content via a rule base architecture. Due to the high computation time of rule base architecture, propagation-based rule mining is now used in modern-day computation. The users generate their requests through an application layer. The application layer passes the request to its concerned forums via the internet. The forums are connecting to data processing centers that could be cloud data centers in this modern time frame. The processing center or the data center has a service manager that analyses the request from the user based on the context that is demanded by the user query. The context evaluation is done with the help of a trained repository and a file log is maintained to write new entry values in the system . The entire process can be termed as context mining.

    Text mining has emerged as one of the most important data processing activities over the last few decades. While it makes the life of millions of everyday users of digital plat- forms and applications much easier, it is a domain that also challenges researchers in numerous ways. The challenges are many fold - ranging from the volume of the data that needs to be processed, storage issues, language identi¿cation challenges and many more. The work in this thesis focuses on one particular aspect of text mining e.g. Key- word identi¿cation for a document. While this may seem to be quite a trivial activity for short passages, it is quite dif¿cult to successfully identify keywords for extremely long text documents. Doing so using an automated systems only adds to the challenge. Everyone in today's world understands the importance of data. In the context of business, data is used to analyze market trends or can be used to understand customer needs. It also helps to understand the user's perspectives and choices. There are var-ious ways that data plays a crucial role in our everyday lives. Most businesses would be bound to fail if they could not comprehend the data that was available. This data could vary from stock indices, to customer feedback, to worker sentiments and numerous other insights. Analyzing data also helps in advertisement noti¿cations or to suggest a piece of relevant information to the user. It also helps to understand the likes and dislikes of a user. It can make for a world with a better user experience in terms of an individuals needs, e.g., if a user is more interested in cricket, we can provide targeted insight to the user about cricket. A customized user experience for a user is more at- tractive than a bland user experience which is homogeneous for everyone. Everyone's needs are different from others as everyone has different perspectives and opinions. We offered examples of keyword extraction, the challenges involved and the major issues faced by designers of keyword extraction algorithms. Finally about some common application areas where keyword extraction is being used in real life scenarios. Attracting users and providing them with better services through relevant data also helps the system to understand the users' needs. A user consciously or unknowingly provides his information for use in business or expresses his views on various platforms. If a user expresses some political opinions, it helps us to tailor his experience better the next time he uses the system.

    The general format of this book is I'll start with each concept, explaining it in a bunch of sections and graphical examples. I will introduce you to some of the notations and fancy terminologies that data scientists like to use so you can talk the same language, but the concepts themselves are generally pretty simple. After that, I'll throw you into some actual Python code that actually works that we can run and mess around with, and that will show you how to actually apply these ideas to actual data.
