class ConllSRLInstance(object): (source)

Constructor: ConllSRLInstance(tree, verb_head, verb_stem, roleset, tagged_spans)

An SRL instance from a CoNLL corpus, which identifies and providing labels for the arguments of a single verb.

Method	`pprint`	Undocumented
Instance Variable	`arguments`	A list of `(argspan, argid)` tuples, specifying the location and type for each of the arguments identified by this instance. `argspan` is a tuple `start, end`, indicating that the argument consists of the `words[start:end]`...
Instance Variable	`roleset`	Undocumented
Instance Variable	`tagged_spans`	A list of `(span, id)` tuples, specifying the location and type for each of the arguments, as well as the verb pieces, that make up this instance.
Instance Variable	`tree`	The parse tree for the sentence containing this instance.
Instance Variable	`verb`	A list of the word indices of the words that compose the verb whose arguments are identified by this instance. This will contain multiple word indices when multi-word verbs are used (e.g. 'turn on').
Instance Variable	`verb_head`	The word index of the head word of the verb whose arguments are identified by this instance. E.g., for a sentence that uses the verb 'turn on,' `verb_head` will be the word index of the word 'turn'.
Instance Variable	`verb_stem`	Undocumented
Instance Variable	`words`	A list of the words in the sentence containing this instance.

arguments: list = (source) ¶

A list of (argspan, argid) tuples, specifying the location and type for each of the arguments identified by this instance. argspan is a tuple start, end, indicating that the argument consists of the words[start:end].

roleset = (source) ¶

Undocumented

tagged_spans = (source) ¶

A list of (span, id) tuples, specifying the location and type for each of the arguments, as well as the verb pieces, that make up this instance.

tree = (source) ¶

The parse tree for the sentence containing this instance.

verb: list = (source) ¶

A list of the word indices of the words that compose the verb whose arguments are identified by this instance. This will contain multiple word indices when multi-word verbs are used (e.g. 'turn on').

verb_head = (source) ¶

The word index of the head word of the verb whose arguments are identified by this instance. E.g., for a sentence that uses the verb 'turn on,' verb_head will be the word index of the word 'turn'.

verb_stem = (source) ¶

Undocumented

words = (source) ¶

A list of the words in the sentence containing this instance.
