def run_cso_classifier_batch_model_single_worker(papers,
modules="both",
enhancement="first"):
"""Run the CSO Classifier in *BATCH MODE*.
It takes as input a set of papers, which include abstract, title, and keywords and for each one of them returns a
list of relevant concepts from CSO. This function requires a dictionary of papers, with each id corresponding to
the metadata of a paper, and few flags:
(i) modules, determines whether to run only the syntactic module, or the semantic module, or both;
(ii) enhancement, controls whether the classifier should infer super-topics, i.e., their first direct
super-topics or the whole set of topics up until root.
Args:
papers (dictionary): contains the metadata of the papers, e.g., for each paper, there is title, abstract and
keywords {"id1":{"title": "","abstract": "","keywords": ""},"id2":{"title": "","abstract": "","keywords": ""}}.
modules (string): either "syntactic", "semantic" or "both" to determine which modules to use when
classifying. "syntactic" enables only the syntatcic module. "semantic" enables only the semantic module.
Finally, with "both" the classifier takes advantage of both the syntactic and semantic modules. Default =
"both".
enhancement (string): either "first", "all" or "no". With "first" the CSO classifier returns only the topics
one level above. With "all" it returns all topics above the resulting topics. With "no" the CSO Classifier
does not provide any enhancement.
Returns:
fcso (dictionary): contains the CSO Ontology.
fmodel (dictionary): contains a cache of the model, i.e., each token is linked to the corresponding CSO topic.
