TRECLMQuerying default constructor initialises the inverted index, the lexicon and the document index structures.

Method Detail

processQueries

public java.lang.String processQueries(double c)

Performs the matching using the specified weighting model from the setup and possibly a combination of evidence mechanism. It parses the file with the queries (the name of the file is defined in the address_query file), creates the file of results, and for each query, gets the relevant documents, scores them, and outputs the results to the result file. The parameter c is not used for language models.

Overrides:

processQueries in class TRECQuerying

Parameters:

c - this parameter is not used for language models.

Returns:

String the filename that the results have been written to

processQueries

public java.lang.String processQueries(double c,
                                       boolean c_set)

Performs the matching using the specified weighting model from the setup and possibly a combination of evidence mechanism. It parses the file with the queries (the name of the file is defined in the address_query file), creates the file of results, and for each query, gets the relevant documents, scores them, and outputs the results to the result file. The parameter c is not used for language models.

Overrides:

processQueries in class TRECQuerying

Parameters:

c - this parameter is not used for language models.

c_set - this parameter is not used for language models.

Returns:

String the filename that the results have been written to

processQueries

public java.lang.String processQueries()

Performs the matching using the specified weighting model from the setup and possibly a combination of evidence mechanism. It parses the file with the queries (the name of the file is defined in the address_query file), creates the file of results, and for each query, gets the relevant documents, scores them, and outputs the results to the result file.

Overrides:

processQueries in class TRECQuerying

Returns:

String the filename that the results have been written to
