Member Function Documentation

static IPosOnlyFeedback Read ( IDataReader  reader,
float  rating_threshold,
IEntityMapping  user_mapping,
IEntityMapping  item_mapping 
) [inline, static]

Read in rating data which will be interpreted as implicit feedback data from an IDataReader, e.g. a database via DbDataReader.

Parameters:
reader the IDataReader to be read from
rating_threshold the minimum rating value needed to be accepted as positive feedback
user_mapping user IEntityMapping object
item_mapping item IEntityMapping object
Returns:
a IPosOnlyFeedback object with the user-wise collaborative data
static IPosOnlyFeedback Read ( TextReader  reader,
float  rating_threshold,
IEntityMapping  user_mapping = null,
IEntityMapping  item_mapping = null,
bool  ignore_first_line = false 
) [inline, static]

Read in rating data which will be interpreted as implicit feedback data from a TextReader.

Parameters:
reader the TextReader to be read from
rating_threshold the minimum rating value needed to be accepted as positive feedback
user_mapping user IEntityMapping object
item_mapping item IEntityMapping object
ignore_first_line if true, ignore the first line
Returns:
a IPosOnlyFeedback object with the user-wise collaborative data
static IPosOnlyFeedback Read ( string  filename,
float  rating_threshold,
IEntityMapping  user_mapping = null,
IEntityMapping  item_mapping = null,
bool  ignore_first_line = false 
) [inline, static]

Read in rating data which will be interpreted as implicit feedback data from a file.

Parameters:
filename name of the file to be read from
rating_threshold the minimum rating value needed to be accepted as positive feedback
user_mapping user IEntityMapping object
item_mapping item IEntityMapping object
ignore_first_line if true, ignore the first line
Returns:
a IPosOnlyFeedback object with the user-wise collaborative data
