Morphological Analysis Quiz

What is the main purpose of a dictionary lookup in morphological analysis?

• To translate a sentence

• To find synonyms

• To find the root form and grammatical information of a word

• To count word frequency

Which of the following is usually stored in a dictionary used in NLP?

• Paragraphs and chapters

• Root word, POS tags, and grammatical features

• Only nouns

• Sentences and their meanings

A Finite State Automaton (FSA) is best described as:

• A machine that solves math equations

• A state machine that processes input symbols step-by-step

• A robot that translates languages

• A spell checker

In the context of morphology, an FSA is used to:

• Accept or reject word forms based on valid transitions

• Translate words into different languages

• Count how many times a word appears

• Summarize a paragraph

What does an FST (Finite State Transducer) produce for the word 'played'?

• Only the word 'play'

• Nothing, it's invalid

• Root word 'play' and features like V (verb), Past

• Only the tense of the word

Which of the following best describes the output of an FST?

• A different language

• Root word + grammatical features

• Just the last letter

• Word frequency

What is one key difference between FSA and FST in morphology?

• FST gives output mappings; FSA only accepts/rejects

• FSA gives more information

• FST is not useful for NLP

• FSA is more complex than FST

What does 'lexicon-free' mean in the context of FST?

• It stores all word meanings

• It does not rely on a pre-built dictionary

• It gives synonyms

• It only uses verbs

Lexicon-free FST systems use what technique to process words?

• Rule-based transformations

• Grammar-checking

• Machine learning

• Voice recognition

Which of these words is most likely over-stemmed by a lexicon-free stemmer?

• Playing → Play

• University → Univers

• Played → Play

• Cats → Cat
