The Indri retrieval model. Indri is an open-source search engine implemented as part of the lemur project by
UMass Amherst and CMU. Refer to http://lemurproject.org/indri.php for more information.
The retrieval model used here is based on language modeling framework and retrieves documents using the query
likelihood retrieval model [Ponte & Croft; SIGIR 1998] and Dirichlet prior smoothing [Zhai and Lafferty; SIGIR
2001]. It is implemented using the Pyndri [Van Gysel et al.; ECIR 2017], which is a python interface to Indri.
Refer to http://lemurproject.org/indri.php for more information on the Lemur toolkit.
Args:
params(dict): A dict containing some parameters. Here is the list of all required parameters:
'indri_path': The path to the installed Indri toolkit.
'index': The path to the Indri index constructed from the collection.
'results_requested': The maximum number of requested documents for retrieval. If not given, it is set to 1.
'text_format': The text format for document collection (e.g., 'trectext').
Note that the parameters 'query_generation' and 'logger' are required by the parent class.
