Data Mining is the process of analyzing large data-sets to identify trends and patterns in the data. The data can be generated through different sources such as social media, websites, transactions, mobile devices, etc. The information extracted from this data helps organizations to derive their real business value and generating new business opportunities. There are various tools and techniques for the data mining process. Also, there are a number of topics in data mining for thesis and research. The term ‘data mining’ is broadly used in the IT industry and it includes activities like collecting, extracting, processing and analyzing data.
Data Mining finds its applications in various areas including sales, marketing, finance, research to name a few. The trends and patterns in data help organizations to make predictions for the business.
Components of Data Mining
Following are the various components of data mining according to different needs:
- Preprocessing – Preprocessing is required to analyze the data-sets.
- Data Cleansing – Removing errors from data so as to prepare data for further exploration.
- Association – Finding relationship among variables of different data-sets.
- Clustering – Grouping data with similar patterns together.
- Classification – Classifying data on the basis of structure.
- Regression – Predicting numeric values of the data.
Applications of Data Mining
Following are the major applications of data mining:
- Financial Data Analysis
- Identifying customer trends
- Checking fraudulent activities in the telecommunication industry
- Biological Data Analysis
- Data Warehousing
- Graph-based mining
- Intrusion Detection
Thesis and Research Areas in Data Mining
If you are looking for hot topics in data mining then you can focus on the following areas of data mining to get a good idea:
- Fraud Detection
- Market Analysis
- Sentiment Analysis
- Graph Mining
- Text Mining
- Social Network Analysis
- Biological Data Mining
Data Mining and its techniques help in detecting fraud in various sectors including banking, finance, insurance, government, and law enforcement. It is one of the hot topics in data mining for thesis and research. There has been a significant increase in the number of fraud attempts in the past few years. In order to tackle these frauds, data mining process and statistics are used. Through these techniques, fraudulent transactions can be checked by identifying different patterns in transactions. To estimate the probability of fraudulent behavior, data mining techniques like decision trees, machine learning, association rules, clustering, and neural network are put into practice. Statistical data analysis techniques are also used for this purpose such as:
- Data preprocessing technique for error correction
- Probability distribution
- Time-series analysis
- Clustering and classification
- Algorithm matching for detecting anomalies in transactions
Data Mining finds its application in the stock market analysis. Patterns are studied to predict the movement of stock market. Artificial Intelligence is combined with this process to study the past and the present financial data. The stock prices are calculated through data mining techniques whereas the decision-making tree is constructed through artificial intelligence strategies. It is also a good topic for the thesis in data mining. This will really help the businesses in the stock market to make better decisions.
Data Mining techniques are used in sentiment analysis to predict consumer emotions. Sentiment Analysis classifies a text into a class. The sentiment classification can be positive/ negative or multi-class problem. The emotions of the users are predicted through texts, posts, and reviews uploaded by the users on different platforms mainly social media. Preprocessing is the first step in the sentiment classification. The sentiment is classified using the following three approaches:
- Machine Learning
For sentiment analysis certain evaluation metrics like Precision, Recall, F-score, and Accuracy. The end results are visualized through graphs, histograms, and confusion matrices.
Graph mining is another good topic in data mining for research and thesis. It is a process in which patterns are extracted from the graphs that represent the underlying data. There are a number of applications of graph mining such as cheminformatics, biological networks of web data, predictive toxicology. There are certain algorithms developed for graph mining.
Text mining or text analytics is a process in which information is extracted from the written sources. It also transforms the unstructured text into the structured data for better analysis. The main purpose of text mining is to identify facts and relationships from the large textual data. It helps businesses and organizations to get valuable insights useful for their business. The main processes in text mining include information retrieval, lexical analysis, pattern recognition, and predictive analytics.
The foremost step in text mining is to organize the data into a more structured form by involving the use of natural language processing technology. Text mining finds its application in sentiment analysis. Other important applications include social media monitoring, bioinformatics, scientific discovery, competitive intelligence. It is a popular area for research in data mining.
Clustering is an unsupervised machine learning method to create groups of data-sets having similar patterns using statistical distribution. Data clustering is used in market research, pattern recognition, data analysis, and image processing. The clustering methods are classified as follows:
- Partitioning clustering method
- Hierarchical clustering method
- Density-based clustering method
- Grid-based clustering method
- Model-based clustering method
- Constraint-based clustering method
Following are the various requirements for clustering in data mining:
- High dimensionality
- Use of different types of attributes
K-means clustering is an important type of clustering used on the undefined data. It is an unsupervised learning method. In this methods, data points are assigned to each k group. The K-means clustering method is used to find the unlabeled groups in the data.
Social Network Analysis
Social Network Analysis is also one of the popular topics in data mining for thesis and research. It is a quantitative and qualitative process that measures the flow of relationship in a social network. The relationship is represented in the form of nodes and links where nodes represent the people and links represent the relationships between the nodes. Mathematical and visual analysis of the human relationship is represented by social network analysis. Data Mining process and techniques are used in the social network analysis.
Biological Data Mining
Data mining find its application in bioinformatics. It is a field that deals in the collection, processing, and collection of the biological data. There are various applications of data mining in bioinformatics such as gene finding, protein function domain detection, protein function interference. Clustering and classification methods of data mining help in microarray data and protein array data analysis. Data mining also offers a solution for analyzing large-scale biological data. It helps in the prediction of functions of anonymous genes. It is also a good area for research and thesis in data mining.
