Web monitoring systems and meta-search engines were designed to
provide time and coverage critical services, where time critical means that new
information should be provided as soon as it is publicized on the web and
coverage critical means that any information should not be missed by the
systems. We have analyzed coverage and timeliness of three commercial search
engines with the web page monitoring results to investigate how rapidly and
how efficiently web monitoring system and meta-search engines collect and
provide newly published web information. We have also assessed how the
meta-search engines might improve coverage and timeliness by providing
collective services. Our experiment results show that commercial search
engines still cover 65% ~ 75% of newly published information, taking from five
to 13 days to retrieve the information. Theoretically, meta-search engines
discover up to 86% of all published data and shorten delay time up to 8 days.
