Lalisio, a social knowledge network, introduced a search and presentation engine from its parent company Q-Sensei. To further expand its offering, Lalisio has integrated arXiv and PubMed Central, two scholarly databases into its literature search service. arXiv provides access to papers from the fields of physics, mathematics, non-linear science, computer science, quantitative biology, and statistics. PubMed Central is a digital archive of biomedical and life science journals and is run by the U.S. National Institute of Health (NIH). The patented search and presentation engine by Q-Sensei offers overviews of the contents of databases. It generates suggestions for search terms relevant to the current stage of the search. The engine connects various categories or "dimensions" of search suggestions allowing for multi-dimensional browsing.
