qb-parser Documentation

qb-parser is a Python package for parsing the questions and answerlines in quizbowl. The answerline parser heavily borrows from qbreader's qb-answer-checker.

Installation

pip install qb-parser

Usage

clue_tokenize()

clue_tokenize() splits quizbowl questions into a list of clues just like nltk's sent_toknize(). It was written because the use of quotes and many periods (e.g. "Symphony No. 9") make quizbowl questions difficult for sent_tokenize().

AnswerLineParser

The AnswerLineParser is designed to parse answerlines containing directives and answers, and returning an Answer object. The answerline parser heavily borrows from qbreader's qb-answer-checker.

parse_answerline(self, answerline: str) -> Answer

• Parameters:
  • answerline: A string containing directives and bracketed answers.
• Returns: An Answer object containing organized directives and answers.

Example Usage

from qb_parser import AnswerLineParser
parser = AnswerLineParser()
answer = parser.parse_answerline("Adventure [accept {Microsoft Adventure} or {Colossal Cave Adventure}; accept {graphic adventures}; prompt on {graphic} with 'what other word is in the name of that genre?']")
print(answer)

Output

(<Directive.ACCEPT: 'accept'>, [('Adventure', ''), ('Microsoft Adventure', ''), ('Colossal Cave Adventure', ''), ('graphic adventures', ''), ('graphic adventure', '')])
(<Directive.REJECT: 'reject'>, [])
(<Directive.REGULAR_PROMPT: 'regular_prompt'>, [('graphic', 'what other word is in the name of that genre?')])
(<Directive.ANTIPROMPT: 'antiprompt'>, [])

Answer

The Answer class describes the answer for a quizbowl question. Internally, it uses a directive_map that, given a Directive (e.g. Directive.ACCEPT), produces a AnswerAction. AnswerAction contains a list of SingleAnswers that contain the answer_text and other useful properties like exact_directed_prompt.

Fields

• directive_map: A dictionary mapping Directive types to AnswerAction objects.

Methods

• getAnswerAction(self, directive: Directive) -> AnswerAction

  • Retrieves an AnswerAction based on the given Directive.
  • Parameters:
    • directive: A Directive enum value.
  • Raises:
    • ValueError if the directive is not found.

• addAnswerAction(self, answerAction: AnswerAction)

  • Adds an AnswerAction to the corresponding directive in directive_map.
  • Parameters:
    • answerAction: An AnswerAction object to add.
  • Raises:
    • RuntimeError if the directive is invalid.
