Description: Web mining challenges refer to the difficulties encountered when extracting data from the web. This process involves the collection, analysis, and transformation of large volumes of information available online, which can be complicated due to the diversity of formats, structures, and access protocols. Web mining faces obstacles such as variability in data quality, the presence of unstructured information, and the need to comply with privacy regulations and copyright laws. Additionally, scraping techniques may be blocked by security measures implemented by websites, further complicating the task of obtaining data. The ability to handle these challenges is crucial for data analysts and scientists seeking to extract valuable information for decision-making, market research, or the development of predictive models. In this context, web mining becomes a powerful tool, but also a field filled with complexities that require innovative and adaptive solutions to overcome existing barriers.
