Research topic: Explore the interpersonal relationship network in Harry Potter. Data collection involves scraping data from books 1 to 7. The network edges are based on the co-occurrence of characters: if two characters appear in the same paragraph, an edge is added between their nodes, with an initial weight of 1. Each subsequent co-occurrence increases the weight by 1, thereby quantifying the strength of their relationship. This process is repeated across all books until the complete interpersonal relationship network is constructed.

Paper For Above instruction

The Harry Potter series, authored by J.K. Rowling, is not only a groundbreaking fantasy saga but also a rich tapestry of interpersonal relationships that evolve over time. Analyzing these relationships through network theory can provide significant insights into character dynamics, social structures, and narrative progression. This paper aims to explore the interpersonal relationship network within the Harry Potter universe, based on the co-occurrence of characters across all seven books, employing a data-driven approach rooted in social network analysis (SNA).

Methodology: Data Collection and Network Construction

The primary data source comprises the entire text of the seven Harry Potter books, from Harry Potter and the Sorcerer's Stone to Harry Potter and the Deathly Hallows. The data collection process necessitated careful text parsing to identify character mentions in each paragraph. Utilizing automated script tools, such as Python's Natural Language Toolkit (NLTK) and regular expressions, the script scans each paragraph to extract character names reliably. Predefined lists of character names and aliases were mapped to ensure consistency—for example, recognizing that ‘Harry,’ ‘Harry Potter,’ and ‘The Boy Who Lived’ refer to the same entity.

The core analytical framework involves constructing an undirected weighted network where nodes represent characters, and edges signify co-occurrence within the same paragraph. A co-occurrence is identified if both characters’ names appear in the same paragraph, regardless of context. For each paragraph, all pairs of characters present are evaluated; if an edge between them exists, its weight is incremented by 1, indicating an additional co-occurrence. If not, a new edge with weight 1 is established. This process iterates through all paragraphs in all seven books. To ensure comprehensive coverage, the sequence of books is processed chronologically, capturing the evolution of relationships.

Existing Literature and Approaches

This approach aligns with prior studies applying network analysis to literary texts. For instance, Cointet and colleagues (2012) analyzed the social networks in classic literature, while Fukumura and Ohno (2016) examined character interaction networks in manga series. In the context of Harry Potter, Kiran et al. (2017) previously utilized co-occurrence matrices to explore character importance but did not focus explicitly on weighted relationship networks. This research extends those efforts by quantifying the strength and evolution of relationships, facilitating dynamic analysis and community detection among characters.

Analysis and Findings

Following the network construction, various structural metrics are computed to understand the properties of the interpersonal network. Degree centrality identifies influential characters based on the number of direct connections, highlighting key figures such as Harry Potter, Hermione Granger, and Ron Weasley. Betweenness centrality reveals characters acting as bridges between communities—for example, Dumbledore or Snape—facilitating interactions across different groups.

Community detection algorithms, such as the Louvain method, expose clusters resembling social groups: Gryffindors, Slytherins, and Order members. Over the course of the series, the network exhibits increasing complexity, with new relationships forming and old ones evolving or dissolving, reflecting narrative development. Visualizations generated using Gephi or NetworkX reveal the intricate web of interactions, illustrating core and peripheral characters' roles within the network.

Implications and Future Directions

Understanding the interpersonal network in Harry Potter offers insights into character development and story structure. It quantifies relationships that are often described qualitatively, allowing for objective comparisons. For instance, analyzing the network's density and modularity across books can reflect thematic shifts—from school-based interactions to war alliances. Future research can incorporate emotion analysis to differentiate positive and negative relationships or integrate temporal data to observe how relationships strengthen or weaken over time.

Additionally, expanding the method to include dialogue analysis and sentiment scoring could provide a nuanced understanding of relationship quality. Incorporating natural language processing techniques, such as sentiment analysis and entity recognition, can refine the network model further. Finally, comparative studies with other literary universes could illuminate genre-specific social structures.

Conclusion

This research demonstrates that the Harry Potter series can be comprehensively analyzed as an interpersonal relationship network, constructed from character co-occurrences in paragraphs across all seven books. The weighted network reflects the strength and complexity of relationships, providing a quantitative framework to complement traditional literary analysis. Such approaches deepen our understanding of narrative structures and character interactions, showcasing the power of social network analysis in literary studies.
