By tailoring the material to your unique needs, this book reveals a clear path to mastering web crawler development without unnecessary detours.

This book offers a detailed look at focused web crawling by examining existing methods and introducing a novel approach called Term Frequency-Information Content (TF-IC). Ali Pesaranghader and Norwati Mustapha present a clear comparison between TF-IC and traditional techniques like TF-IDF and Latent Semantic Indexing, highlighting improvements in weighting terms within multi-term topics. You’ll gain a solid understanding of how to enhance focused crawlers through information content analysis, which is particularly useful if you work on search engine optimization or data mining. The authors break down complex concepts into manageable sections, making it practical for those aiming to refine web data retrieval processes.

Yan Wang tackles one of the trickiest aspects of web crawling: efficiently extracting data hidden behind search interfaces in the deep web. Instead of relying on hyperlink navigation like traditional crawlers, Wang explores how to strategically select queries to unearth vast amounts of data locked in databases and dynamic sources. You learn about common challenges such as the cold start problem and return limits, and Wang offers a novel technique to overcome these, backed by detailed analysis. This book suits developers and researchers focused on improving crawler efficiency when dealing with complex data retrieval beyond the surface web.
