Question

Many mobile news apps offer personalised content based on what users read, watch, or search for. As a media researcher, how would you study audience behaviour using data from such an app (e.g., time spent on articles, categories browsed, or frequency of visits)? What patterns would you look for to understand user preferences, and how could this help improve the content shown to different users?

Studying audience behaviour in mobile news applications that offer personalised content requires a systematic approach involving data collection, data processing, pattern identification, and actionable insights. As a media researcher, the focus would be on leveraging both Data Science and Big Data techniques to understand how users interact with the app, what content they prefer, and how their engagement changes over time. This process involves integrating structured data (e.g., article categories, timestamps) with unstructured data (e.g., article text, multimedia content) and applying advanced analytical methods to uncover meaningful behavioural patterns. The first step would involve data acquisition. The mobile news app can generate massive amounts of user interaction data, such as the time spent on specific articles, the number of times a user visits the app per day or week, categories of articles read (e.g., politics, sports, entertainment), search queries, video plays, likes, shares, and even scroll depth within articles. This data would be collected in raw form from user logs, clickstream data, and app analytics systems. Since this involves potentially millions of users and billions of data points, Big Data storage technologies such as Hadoop Distributed File System (HDFS) or cloud-based platforms like AWS S3, Azure Data Lake, or Google BigQuery would be essential for storing and retrieving the data efficiently. Next would be data preprocessing and cleaning, which is crucial before any analysis. The raw data often contains noise, inconsistencies, and missing values. For example, session times might be incomplete if a user closes the app abruptly, or article categories might be incorrectly tagged. Data Science techniques such as handling null values, normalising timestamps, standardising category labels, and detecting anomalies (e.g., unusually high time spent due to the app being left open in the background) would be applied. This step ensures the data’s integrity and reliability for further analysis. The core analysis would focus on identifying audience behaviour patterns. Descriptive analytics would be the starting point to summarise the data. For instance, calculating the average time spent per article, the most _________ ______ _________ _________ _________ _________ _____.
