analysis_thread/atree_list_try_cell [ Functions ]

[ Top ] [ analysis_thread ] [ Functions ]

NAME

atree_list_try_cell -- dispatch according to the cell_type and call the right function

SYNOPSIS

458     atree_list_try_cell(ms, cell_type, pei);

FUNCTION

The function calls the right function to handle the list cell in respect of its type. The type is given by the cell_type parameter. The cell is an item of the list found in the trie.

INPUTS

ms - the analysis structure
cell_type - a type of the cell
pei - a union describing the scheme or form

RESULT

void, but accumulated in ms->lresults

analysis_thread/atree_try_der_cell [ Functions ]

[ Top ] [ analysis_thread ] [ Functions ]

NAME

atree_try_der_cell -- goes through the hash list and adds all the results

SYNOPSIS

398     atree_try_der_cell(ms, maw);

INPUTS

ms - the analysis structure
maw - the pattern structure

RESULT

void, but accumulated in ms->lresults

analysis_thread/find_lr [ Functions ]

[ Top ] [ analysis_thread ] [ Functions ]

NAME

find_lr -- find a lemma result

SYNOPSIS

78     struct TRLemma *lr = find_lr(ms, lm_idx, attr_atom);

FUNCTION

The function finds a record in the ms->lresults stack using the ms->lht map. The record is specified by the lm_idx index parameter and attr_atom.

If the record is found, the lm_idx key string is removed from the ms->char_stack. Otherwise the record is created, registered into the hash table and initialized. The tag_list field is initialized with an empty list.

The string key is found in the hash table but the records differs in the attr_atom field, the former key storage is reused and new one is wipped out from the ms->char_stack.

INPUTS

ms - the analysis structure
lm_idx - index of the beginning of the last inserted lemma into the ms->char_stack
attr_atom - just a natural value (attribute atom).

RESULT

lr - a pointer to the lemma result structure. The pointer shouldn't be hold over insert operations on the ms->lresults.

analysis_thread/form_constr_lemma [ Functions ]

[ Top ] [ analysis_thread ] [ Functions ]

NAME

SYNOPSIS

422     natural idx = form_constr_lemma(ms, f);

FUNCTION

The function concatenates several strings to get the resulting lemma. It uses ms->lemma_p to start with the prefix and continues with a part of the ms->form_str derived with the f->cut_idx string instruction.

INPUTS

ms - the analysis structure
f - a form description structure

RESULT

The index idx to the ms->char_stack is returned.

SYNOPSIS

350     natural idx = hash_der_cell_constr_lemma(ms, maw, fc);

FUNCTION

The function concatenates several strings to get the resulting lemma. It uses ms->lemma_p to start with the prefix and continues with kofix derived from ms->form_str possibly with the modification by the maw->rt2lmm_idx string instruction. Then it is finished by the fc.cut_idx string instruction.

INPUTS

ms - the analysis structure
maw - the pattern structure
fc - the tag group and cut_idx from the compound scheme from the scheme hash table

RESULT

The index idx to the ms->char_stack is returned.

analysis_thread/merge_tags [ Functions ]

[ Top ] [ analysis_thread ] [ Functions ]

NAME

merge_tags -- merges the tg_idx tags to the lemma result; all megre_tags_XX functions are documented here

SYNOPSIS

198     ms->merge_tags(ms, lr, tg_idx);

FUNCTION

The function filters valid tags from the list and adds them to the lr->tag_list.

The tag validity definition changes with the particilar function.

The function merge_tags_ng considers the tag to be valid if:

if admits negation by the negation joker or if the negation is required and the tag is affirmative and a noun or an adjective or a verb or if the negation is not required
and (conjunction) it admits grading by the grading joker or if the grading is required and the tag is comparative and an adjective or an adverb or the grading is not required.

The function merge_tags_prefix accepts tags that are not abbreviations and are compatible with the recognized prefix, i.e. if it is a noun or an adjective with the nominal prefix type or a verb with the verb prefix type.

The function merge_tags_prefix_ng combines the restriction on prefix and negation and grading.

The functions merge_tags_simple, merge_tags_fallback and merge_tags_number accept all tags. They only differs in source attribute.

INPUTS

ms - the analysis structure
lr - the lemma result structure to which the tags should be added
tg_idx - the index to the ms->ma->int_rep; it specifies the tags to be added; the list end is marked by NATURAL_MAX

RESULT

void

FUNCTION

The function iterates through the list found in a node of the trie.

INPUTS

ms - the analysis structure
list_addr - an address of the head of the list; the list is stored in the ms->ma->pei_rep repository

RESULT

void, but accumulated in ms->lresults
