Corpus API

Corpus classes 

Base corpus 

class polyglotdb.corpus.BaseContext(*args, **kwargs)[source]

Base CorpusContext class. Inherit from this and extend to create more functionality.

Parameters:

*args: If the first argument is not a CorpusConfig object, it is the name of the corpus
**kwargs: If a CorpusConfig object is not specified, all arguments and keyword arguments are passed to a CorpusConfig object

Phonological functionality 

class polyglotdb.corpus.PhonologicalContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with phones

Syllabic functionality 

class polyglotdb.corpus.SyllabicContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with syllables

Lexical functionality 

class polyglotdb.corpus.LexicalContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with words

Pause functionality 

class polyglotdb.corpus.PauseContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with non-speech elements

Utterance functionality 

class polyglotdb.corpus.UtteranceContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with utterances

Audio functionality 

class polyglotdb.corpus.AudioContext(*args, **kwargs)[source]: Class that contains methods for dealing with audio files for corpora

Summarization functionality 

class polyglotdb.corpus.SummarizedContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with summary measures for linguistic items

Spoken functionality 

class polyglotdb.corpus.SpokenContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with speaker and sound file metadata

Structured functionality 

class polyglotdb.corpus.StructuredContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with metadata for the corpus

Annotation functionality 

class polyglotdb.corpus.AnnotatedContext(*args, **kwargs)[source]: Class that contains methods for dealing specifically with annotations on linguistic items (termed “subannotations” in PolyglotDB

Omnibus class 

class polyglotdb.corpus.CorpusContext(*args, **kwargs)[source]

Main corpus context, inherits from the more specialized contexts.

Parameters:

argsargs: Either a CorpusConfig object or sequence of arguments to be passed to a CorpusConfig object
kwargskwargs: sequence of keyword arguments to be passed to a CorpusConfig object

Corpus structure class 

class polyglotdb.structure.Hierarchy(data=None, corpus_name=None)[source]

Class containing information about how a corpus is structured.

Hierarchical data is stored in the form of a dictionary with keys for linguistic types, and values for the linguistic type that contains them. If no other type contains a given type, its value is None.

Subannotation data is stored in the form of a dictionary with keys for linguistic types, and values of sets of types of subannotations.

Parameters:

datadict: Information about the hierarchy of linguistic types
corpus_namestr: Name of the corpus

Corpus config class 

class polyglotdb.config.CorpusConfig(corpus_name, data_dir=None, **kwargs)[source]

Class for storing configuration information about a corpus.

Parameters:

corpus_namestr: Identifier for the corpus
kwargskeyword arguments: All keywords will be converted to attributes of the object

Attributes:

corpus_namestr: Identifier of the corpus
graph_userstr: Username for connecting to the graph database
graph_passwordstr: Password for connecting to the graph database
graph_hoststr: Host for the graph database
graph_portint: Port for connecting to the graph database
enginestr: Type of SQL database
base_dirstr: Base directory to store information and temporary files for the corpus defaults to “.pgdb” under the current user’s home directory
