| Summary: | Web crawler visits websites for the purpose of indexing. The dynamic nature of today’s web makes the
crawling process harder than before as web contents are continuously updated. In addition, crawling speed
is important considering tsunami of big data that need to be indexed among competitive search engines.
This research project is aimed to provide survey of current problems in distributed web crawlers. It then
investigate the best crawling speed between dynamic globally unique identifiers (GUIDs) and the
traditional static identifiers (IDs). Experiment are done by implementing Arachnot.net web crawlers to
index up to 20000 locally generated URLs using both techniques. The results shown that URLs crawling
time can be reduced up to 7% by using GUIDs technique instead of using IDs. |
