RefSeek is a web search engine for students and researchers that aims to make academic information easily accessible to everyone. RefSeek searches more than five billion documents, including web pages, books, encyclopedias, journals, and newspapers.
RefSeek’s unique approach offers students comprehensive subject coverage without the information overload of a general search engine—increasing the visibility of academic information and compelling ideas that are often lost in a muddle of sponsored links and commercial results.
Traditional search engines rely mostly on keyword matching. Usually, they match the keywords you type in the search field with words found in the indexed content. The accuracy of the search results depends on the quality of the keywords you type, which puts the responsibility of a successful search on the user.
It is different because it employs natural language processing to understand and remember the knowledge conveyed in each document. MA then applies a technique known as semantic inference to recognize the user’s intent and to proactively deliver results relevant to the user’s intention. As a result, MA can process complex queries and can provide rich and knowledgeable answers.” Taken from Microsoft Academic FAQ page accessed 13.01.2020 https://academic.microsoft.com/faq
