Class Summary

AbstractDT	An abstract class for IR datatypes.
NameDT	A class for the IR datatype "name", containing the two deterministic operators "soundex" (soundex similarity) and "plainname" (equality).
NumberDT	A class for the IR datatype "number", containing the deterministic operators "<", "<=", ">", ">=" and the vague operators "~<", "~>" and "~=".
TextDT	A class for the IR datatype "text", containing the operators: "contains": with stemming and stop word removal, BM25 indexing weights, experimental use only "stemen": English stemming and stop word removal, BM25 indexing weights "nostem": without stemming, but with stop word removal, BM25 indexing weights "stemen_tf": English stemming and stop word removal, normalised TF indexing weights "nostem_tf": without stemming, but with stop word removal, normalised TFindexing weights By default, the RSVs are divided by the maximum RSV, and no logistic mapping function is applied.
