The goal of matching this performance in a manner consistent with the inference network model originally motivated the work presented in this article, as well as providing a benchmark against which performance of
Boolean operators based on PIC matrices could be compared.
PubMed searches can be refined by using multiple search terms connected by
Boolean operators: AND, OR, and NOT.
* If the selected node is a
Boolean operator, mutate it into another
Boolean operator from the same arity value and type.
* The participants' knowledge of the use of
Boolean operators increased to a great extent (from 6.8% to 30.8%) after ILI.
The goals of this session are for students to practice basic research strategies including key concepts, alternate search terms,
Boolean operators, and truncation, and immediately apply this knowledge by finding relevant articles in appropriate databases for their assignment.
SciFinder does not use
Boolean operators to construct search queries and, instead, recommends the use of prepositions in the search query to help the database identify the main research concepts.
The search facility is very powerful despite a certain disregard for the
Boolean operators so dear to librarians' hearts.
