PolyMeta Search and Clustering Engine
PolyMeta is an advanced Web 2.0 metasearch (federated search) and clustering engine. PolyMeta enables organizations and individuals to simultaneously search diverse information resources on the Web with a common interface. The search results are merged, ranked and presented in relevance order.
PolyMeta employs powerful Natural Language Processing and Information Retrieval algorithms in its query analysis and refinement, search strategy, relevancy ranking, focused drill-down and exploration of multi-dimensional information spaces.

Why Metasearch?
|
- Information on the Web is inherently heterogeneous: content is distributed on multiple servers in multiple locations, formats and languages aimed for diverse audiences and purposes
- Even the largest of the search engines, Google or Yahoo indexes only a portion of all Web pages. You can't find everything on every search engines: See an example
- The “Hidden Web” of content databases (e.g. PubMed, Web of Science) is estimated to be thousands of times larger than the Open Web.
- Both the Open Web and the Hidden Web are characterized by problems of information coverage, quality, overload, relevancy, currency and completeness, as well as language ambiguity and incompatible user interfaces
- Metasearch Engines may simultaneously search multiple Open Web and Hidden Web sites in order to increase content coverage, precision, relevance and/or search efficiency and effectiveness
