Automated Extraction of Data from Insurance Websites

Sammanfattning

Websites have become a critical source of information for many organizations in today's digital era. However, extracting and organizing semi-structured data from web pages from multiple websites poses challenges. This is especially true when a high level of automation is desired while maintaining generality. A natural progression in the quest for automation is to extend the methods for web data extraction from only being able to handle a single website to handling multiple ones, usually within the same domain. Although these websites share the same domain, the structure of the data can vary greatly. A key question becomes how generalized such a system can be to encompass a large number of websites while maintaining adequate accuracy. The thesis examined the efficiency of automated web data extraction on multiple Swedish insurance company websites. Previous work showed that good results can be achieved with a known English data set that contains web pages from a number of domains. The state-of-the-art model MarkupLM was chosen and trained with supervised learning using two pre-trained models, a Swedish and an English model, on a labeled training set of car insurance customers' web data using zero-shot learning. The results show that such a model can achieve good accuracy on a domain scale with Swedish as the source language with a relatively small data set by leveraging pre-trained models.
