One role must be given, but it is possible so you’re able to indicate two if not most of the about three, with respect to the matter.
Practical question is actually sent to help you Lucene for example full Lucene query sentence structure is actually enjoy. When the new features can be used for example query extension together with microarray filter out (demonstrated after), the user question is intercepted and you may reformulated prior to are published to Lucene. In what uses, the most common options whenever specifying questions is actually depicted which have instances. A concern who has one of the arguments, e. Instance question have a tendency to make as a reply a collection of semantic relations used to have an instant report about a concept.

Table 2
Including shown is where several times good semantic variety of appears as a disagreement in semantic affairs and you may semantic family relations era. Only the common twenty five semantic designs are given out-of 133.
In the examples shown over i didn’t consider new subject, family and you may/or target explicitly, but instead implicitly. A query for example “donepezil treats down syndrome” looks every terms throughout the fresh fields of one’s relations.
