VERSION

DESCRIPTION
t-layer (tectogrammatical) node
METHODS
Access to a-layer (analytical nodes)
- $node->add_aux_anodes(@aux_anodes)
-
Add auxiliary a-nodes (to
a/aux.rf
) - @anodes = $node->get_anodes()
-
Return a-nodes (both auxiliary and lexical, ie.
a/aux.rf
anda/lex.rf
) - @aux_anodes = $node->get_aux_anodes()
-
Return auxiliary a-nodes (from
a/aux.rf
). - $lex_anod = $node->get_lex_anode()
-
Return the lexical a-nodes (from
a/lex.rf
). - $node->set_aux_anodes(@aux_anodes)
-
Set the auxiliary a-nodes (to
a/aux.rf
). - set_lex_anode
-
Set the lexical a-node (to
a/lex.rf
). - $node->remove_aux_anodes(@to_remove)
-
Remove the specified a-nodes from
a/aux.rf
(if they are contained in it). - $node->get_coref_nodes()
-
Return textual and grammatical coreference nodes (from
coref_gram.rf
andcoref_text.rf
). If the document follows the PDT3.0 annotation style, the same steps as for$node-
get_coref_text_nodes()> are applied. - $node->get_coref_gram_nodes()
-
Return grammatical coreference nodes (from
coref_gram.rf
). - $node->get_coref_text_nodes()
-
Return textual coreference nodes (from
coref_text.rf
if the document follows the PDT2.0 annotation style). If the document follows the PDT3.0 annotation style, the list of nodes is extracted fromcoref_text/target_node.rf
. If thewith_types
parameter is set inarg_ref
, two list references are returned: the first one refers to a list of nodes extracted fromcoref_text/target_node.rf
, the second one to a list of types fromcoref_text/type
. - $node->add_coref_gram_nodes(@nodes)
-
Add grammatical coreference nodes (to
coref_gram.rf
). - $node->add_coref_gram_nodes(@nodes)
-
Add textual coreference nodes (to
coref_text.rf
). - $node->remove_coref_nodes()
-
Remove the specified nodes from
coref_gram.rf
orcoref_text.rf
(if they are contained in one or both of them). - $node->update_coref_nodes()
-
Remove all invalid coreferences from
coref_gram.rf
andcoref_text.rf
. - $node->get_bridging_nodes()
-
Access the nodes referred from the current node by bridging anaphora (in
bridging
attribute). The method returns references to two lists of the equal length: the referred nodes and the types of bridging relations. - $node->add_bridging_node($node, $type)
-
Add bridging anaphora to
$node
of type$type
(tobridging
). - $node->get_appos_expansion($arg_ref?)
-
If the node is part of an apposition (no matter whether as a root or a member), return all the nodes that constitute the apposition. Only the apposition root may be excluded from the selection if the option
with_appos_root
is off. The method is used to abstract from the technical implementation of appositions. So far, it is used by coreference accessors.OPTIONS
- with_appos_root
-
Include the apposition root. Disabled by default.
Access to source language t-layer (in MT)
- $src_tnode = $node->src_tnode()
-
Return the source language (in MT) t-node (from
src_tnode.rf
). - set_src_tnode
-
Set the source language (in MT) t-node (to
src_tnode.rf
).
Access to n-layer (named entity nodes)
Note there is no set_n_node
method. You must set the link from n-node to a a-node.
- $node->get_n_node()
-
This is a shortcut for
$self->get_lex_anode()->n_node;
If this t-node is a part of a named entity, this method returns the corresponding n-node (Treex::Core::Node::N). If this node is a part of more than one named entities, only the most nested one is returned. For example: "Bank of China"$n_node_for_china = $t_node_china->get_n_node(); print $n_node_for_china->get_attr('normalized_name'); # China $n_node_for_bank_of_china = $n_node_for_china->get_parent(); print $n_node_for_bank_of_china->get_attr('normalized_name'); # Bank of China
Other methods
- is_coap_root
-
Is this node a root (or head) of a coordination/apposition construction? On t-layer this is decided based on
functor =~ /^(CONJ|CONFR|DISJ|GRAD|ADVS|CSQ|REAS|CONTRA|APPS|OPER)/
.
