  During a talk at the New England Database Day conference at the Massachusetts Institute of Technology, Google's Alon Halevy admitted that the search giant has "not been doing a good job" presenting the structured data found on the web to its users. By "structured data," Halevy was referring to the databases of the "deep web" - those internet resources that sit behind forms and site-specific search boxes, unable to be indexed through passive means.
  Google's Deep Web Search
  
  Halevy, who heads the "Deep Web" search initiative at Google, described the "Shallow Web" as containing about 5 million web pages while the "Deep Web" is estimated to be 500 times the size. This hidden web is currently being indexed in part by Google's automated systems that submit queries to various databases, retrieving the content found for indexing. In addition to that aspect of the Deep Web - dubbed "vertical searching" - Halevy also referenced two other types of Deep Web Search: semantic search and product search.
  
  Google wants to also be able to retrieve the data found in structured tables on the web, said Halevy, citing a table on a page listing the U.S. presidents as an example. There are 14 billion such tables on the web, and, after filtering, about 154 million of them are interesting enough to be worth indexing.
  Can Google Dig into the Deep Web?
  
  The question that remains is whether or not Google's current search engine technology is going to be adept at doing all the different types of Deep Web indexing or if they will need to come up with something new. As of now, Google uses the Big Table database and MapReduce framework for everything search related, notes Alex Esterkin, Chief Architect at Infobright, Inc., a company delivering open source data warehousing solutions. During the talk, Halevy listed a number of analytical database application challenges that Google is currently dealing with: schema auto-complete, synonym discovery, creating entity lists, association between instances and aspects, and data level synonyms discovery.
