Conllu Parsing and Searching
Parse and Search through a conllu file
Searching is as follows:
Tree search: The '{' character
If you would like to search with a tree(i.e you want to search for a word with a HEAD value or word), you create your search with a '{'. Then, between the words you are searching for a relation between add a '>'. You can also use and '<' if you are searching for a word that is a dependent of another word. This, the '<', will find the dependent word. For instance, if you wanted to see when 'have' did action to 'clue' (i.e. I have no clue') you could do it like this:
For example python conlluparse.py "text.conllu" '{have>clue' might output:
Token: 2, Form: have, Lemma: have, UPOSTAG: VERB, HEAD: 0, DEPREL: root, # sent_id = 2, Sentence: I have no clue .
If you wanted, you could also be more specific or ambigious with your searches. When you specify these arguments, you also need to make sure that you concatenate "Form=" with the word you are searching for. When you have nothing specified on one side, you need to add 'none=none' to that side. For instance if you wanted to find if something was a dependent of 'have', you could do:
{none=none<form=have
When searching with attributes (i.e UPOSTAG), you could do this like:
python conlluparse.py "text.conllu" '{upostag=verb, form=have>form=clue' which may output:
Token: 2, Form: have, Lemma: have, UPOSTAG: VERB, HEAD: 0, DEPREL: root, # sent_id = 2, Sentence: I have no clue .
You can search with any of these tags - upostag, xpostag, lemma, or deprel. You would do this by just putting the tag name + and '=' and then the actual value. Concatenate the tag an '=' and the value like upostag=noun' or 'lemma=clue' or @.
You can also specify attributes instead of 'form=clue' such as 'upostag=noun'
Token: 2, Form: have, Lemma: have, UPOSTAG: VERB, HEAD: 0, DEPREL: root, # sent_id = 2, Sentence: I have no clue .
Now, instead, if you search with python conlluparse.py "text.conllu" '{form=clue<none=none' , it will print:
Token: 4, Form: clue, Lemma: clue, UPOSTAG: NOUN, HEAD: 2, DEPREL: obj, # sent_id = 2, Sentence: I have no clue .
The tree searches essentially combines all the searches terms. You can search for a word with a specific deprel or upostag like
{@root, upostag=noun>none=none
You can search for relationships like the ; character:
{@nsubj>upostag=noun
You can search for a plain word like:
{form=have>none=none
This will output the same thing as what the other searches would do. Use other searches to distinguish between what you are searching for.
Examples
python conlluparse.py "text.conllu" ':[aux, pres]'
This is how you would run the program with the ':' Could output:
Token: 5, Form: жатырсыздар, Lemma: жат, UPOSTAG: AUX, HEAD: 4, DEPREL: aux, # sent_id = akorda-random.tagged.txt:44:775, Sentence: - Сіздер осында тұрып жатырсыздар ал Астанада жұмыс істейсіздер .
python conlluparse.py "text.conllu" ';nsubj:verb'
This is how you would run the program with the ';' Could output:
Token: 7, Form: секіреді, Lemma: секір, UPOSTAG: VERB, HEAD: 0, DEPREL: root, # sent_id = Ер_Төстік.tagged.txt:22:380, Sentence: Қуып келе жатқан Төстік Төстік те өрмектен секіреді .
python conlluparse.py "text.conllu" "{none=none>none=none, @obj"
This is how you would run the program with the ';' Could output:
Token: 6, Form: іліп, Lemma: іл, UPOSTAG: VERB, HEAD: 0, DEPREL: root, # sent_id = Ер_Төстік.tagged.txt:23:396, Sentence: Сөйткенде Төстіктің бір бақайы өрмекті іліп кетеді .
python conlluparse.py "text.conllu" '<іліп'
This is how you would run the program with the '<' Could output:
Token: 6, Form: іліп, Lemma: іл, UPOSTAG: VERB, HEAD: 0, DEPREL: root, # sent_id = Ер_Төстік.tagged.txt:23:396, Sentence: Сөйткенде Төстіктің бір бақайы өрмекті іліп кетеді .
