ClassifyQueryTerms automatically classifies query terms based on the semantic type of the query.

ConstructQuery takes three slices and creates a query from them.

CutDevelopmentTerms takes terms from the development set where the DF of the term is >= 20%.

CutDevelopmentTermsWithPopulation takes terms where the DF in the population collection is <= 2%.

FetchDocuments retrieves the references to studies of target PMID(s).

FilterQueryTerms reduces further query terms by identifying the best combination of terms based on how many relevant documents they retrieve from the development set.

GetPopulationSet retrieves a set of publications to form a population set.

MetaMapTerms maps terms to CUIs.

RankTerms ranks a map of terms by document frequency.

TermFrequencyAnalysis computes the document frequency for the input documents.

SemTypeMapping is a mapping of STY->Classification.
