ESPs (enterprise search platforms) is the collection of some technologyies, these new, comprehensive bundles of search and integration technologies unlock information tucked away in data stores across the enterprise. The goal of ESPs is deceptively simple: to take fairly simple queries and return the most relevant results possible, all in one place. But under the hood, ESPs aggregate a host of emerging technologies such as autocategorization, entity extraction, and NLP (natural language processing). With an ESP as a foundation, businesses can build customized search applications while automating the process of preparing documents for archiving and indexing.
