Classes in de.unidu.is.retrieval.pire.dt that implement DT

class	AbstractDT An abstract class for IR datatypes.
class	NameDT A class for the IR datatype "name", containing the two deterministic operators "soundex" (soundex similarity) and "plainname" (equality).
class	NumberDT A class for the IR datatype "number", containing the deterministic operators "<", "<=", ">", ">=" and the vague operators "~<", "~>" and "~=".
class	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.
class	TextGermanDT 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.
class	YearDT A class for the IR datatype "year", containing the deterministic operators "<", "<=", ">", ">=" and the vague operators "~<", "~>" and "~=".
