X-Search mines the web for millions of experts

Millions of experts exist in the world; most of them leave tracks on the web through scientific literature, patents, research center corporate websites, blogs, forums etc. X-Search, PRESANS Expert Search Engine technology allows automatically building network of Expert (expertise mapping).

  • The “crawling module” constantly crawls tens of millions of these scientific sources to collect relevant information.
  • Collected information is then analyzed (indexed and structured): the engine automatically builds a real-time network of experts. Experts are described by a number of fields including contact details, institution, collaborations, and field of expertise.
  • The “visible part” of the search engine is a search bar. A query corresponding to the scientific need is launched through the search bar. The engine returns a list of potential qualified experts. A ranking function ranks most relevant experts first.

Technological innovations

Dr Vassilis Plachouras and his team at PRESANS have made a series of technological innovations to provide the following advantages to X-Search:

  • Structuring: the “entity recognition module” recognizes and analyses textual documents referring to potential experts and builds structured expert profiles.
  • Intelligent: semantic analysis and supervised machine learning give sense to the query and allow suggestion of relevant experts beyond a simple keyword search.
