verbnetreader

Read VerbNet and build a list of allowed VerbNet frame for each verb

class verbnetreader.VerbnetReader(path, normalize=False)

Bases: builtins.object

Class used to parse VerbNet and build its representation in memory.

Variables:verbs – Dictionary of VerbnetOfficialFrame lists representing VerbNet.

_build_frame(xml_frame, vnclass, role_list, restrictions)

Parse one frame

Parameters:

• xml_frame (xml.etree.ElementTree.Element.) – XML representation of the frame.
• vnclass (str.) – The VerbNet class to which the frame belongs.

_build_semantics(xml_semantics)

_build_structure(base_structure, syntax_data, vnclass, role_list)

Build the final structure from base_structure

Parameters:

• base_structure (str List) – The base structure
• syntax_data (xml.etree.ElementTree.Element) – The XML “SYNTAX” node
• vnclass (str) – The VerbNet class of the frame

Returns:

(str | str List) List – the final structure

_format_syntax_roles(xml_syntax)

_handle_class(xml_class, parent_frames, role_list, restrictions)

Parse one class of verbs and all its subclasses.

Parameters:

• xml_class (xml.etree.ElementTree.Element.) – XML representation of the class of verbs.
• parent_frames (VerbnetOfficialFrame list.) – the frame inherited from the parent class.

_handle_lex(xml, base_structure)

Choose wether or not to keep a <LEX> entry

Parameters:xml – The <LEX> entry.

:type xml:xml.etree.ElementTree.Element. :param base_structure: The VerbNet primary structure. :type base_structure: str List. :returns: String the lexeme value if accepted, “” otherwise

_handle_prep(xml)

Generate the list of acceptable preposition from a <PREP> entry

Parameters:xml – The <PREP> entry.

:type xml:xml.etree.ElementTree.Element. :returns: String List - the list of acceptable prepositions

_normalized()

_read_syntax_data(index_xml, syntax_data, elem, base_structure)

Look for a node of SYNTAX that match the current element and tells whether a keyword was found between the old and new position

Parameters:

• index_xml – The current position
• syntax_data (xml.etree.ElementTree.Element) – The XML “SYNTAX” node
• elem (str) – The element to look for (VerbNet syntax)
• base_structure (str List) – The frame base structure (for _handle_lex)

Returns:

(int, str) – the new position and a keyword if one is found
