[bioontology-support] [bioportal-announce] BioPortal 3.7 Released

We are pleased to announce the release of BioPortal 3.7. The major new
features in this release are:


.         The term search web service and UI now supports some simple
Boolean logic. The format is backwards compatible with our previous format
so entering "heart attack" still results in terms which contain both words
(a logical AND). Negation is indicated with a minus sign prefix (as in
Google search). For example, searching on "heart attack -fear -anxiety"
returns terms containing both "heart" and "attack" but not those that
refer to a "fear of a heart attack" or "anxiety about a heart attack". A
logical OR is achieved by enclosing words in parenthesis. For example
"(heart attack)" returns terms which contain either "heart" or "attack". *


.         We have regenerated all lexical mappings ("LOOM mappings")
between all terms in all ontologies. The mapping algorithm creates a
mapping between two terms if the names of the two terms are identical
except for case and spacing. LOOM mappings are created between terms if
there is a match between the preferred name of one term and the preferred
name or synonym of another term. *


.         We now have a beta version of an RDF triple store up and
available for use. (The alpha version is no longer available.) This
service provides direct SPARQL access to the ontologies in BioPortal. A
demonstration user interface with SPARQL examples is available at This triple store contains all ontologies
available in BioPortal (updated nightly). *
