TEXT MINING OF TWITTER DATA: TOPIC MODELLING

Abstract:

Twitter has emerged as a valuable source of real-time information and a platform for expressing opinions, sharing news, and discussing various topics. The massive volume and dynamic nature of Twitter data pose significant challenges for extracting meaningful insights. Text mining techniques, such as topic modelling, have become essential tools for analyzing and understanding the vast amount of textual data generated on Twitter.

This abstract provides an overview of the application of text mining and specifically focuses on topic modelling techniques for Twitter data. Topic modelling is a popular unsupervised machine learning method that aims to discover hidden thematic structures within a collection of documents. By applying topic modelling to Twitter data, researchers and data scientists can uncover prevalent themes, identify trending topics, and gain insights into public opinion and sentiment.

This abstract discusses the key steps involved in text mining of Twitter data using topic modelling. It begins with the data collection process, including Twitter API access and the retrieval of relevant tweets based on specific criteria, such as keywords, hashtags, or user profiles. Preprocessing techniques, such as tokenization, stop-word removal, and stemming, are then applied to clean the text data and prepare it for topic modelling.

Next, the abstract explores different topic modelling algorithms commonly used for Twitter data analysis, such as Latent Dirichlet Allocation (LDA) and Non-negative Matrix Factorization (NMF). These algorithms automatically identify latent topics within the tweet corpus by analyzing the co-occurrence patterns of words and capturing the underlying semantic relationships.

The evaluation of topic models is also discussed, including metrics for assessing the coherence, interpretability, and stability of the identified topics. Additionally, strategies for visualizing and interpreting the results are presented, such as word clouds, topic distributions, and topic evolution over time.

Finally, the abstract highlights some practical applications of text mining and topic modelling of Twitter data, including social media monitoring, brand sentiment analysis, event detection, and opinion mining. It emphasizes the importance of leveraging topic modelling techniques to extract valuable insights from Twitter data for various domains, such as marketing, public opinion research, and crisis management.

In conclusion, text mining and topic modelling techniques offer powerful approaches for analyzing and understanding the vast amount of textual data generated on Twitter. By employing these methods, researchers and practitioners can uncover hidden themes, identify trends, and gain valuable insights from Twitter data, enabling them to make data-driven decisions and understand the pulse of public opinion.
