NLP Discourse

What is discourse in the context of NLP?

• A coherent structure of sentences

• Spoken or written communication

• The analysis of lexical choices

• The study of grammar

Which of the following is a key aspect of discourse analysis?

• Discourse segmentation

• Cohesion chain

• Lexical ambiguity

• Phonetics

What does cohesion refer to in discourse analysis?

• The overall structure of a text

• The logical flow of ideas

• The linguistic ties that bind text elements together

• The syntactic complexity of sentences

What does TF-IDF stand for?

• Term Frequency-Inverse Document Formation

• Term Frequency-Inverse Discourse Formation

• Term Frequency-Inverse Document Frequency

• Text Formation-Inverse Document Frequency

In discourse segmentation, what does cosine similarity measure?

• The frequency of terms in a document

• The similarity between vectors representing text blocks

• The syntactic complexity of sentences

• The coherence of a discourse

What is the main goal of TextTiling in discourse segmentation?

• Identifying distinctive terms

• Assessing lexical ambiguity

• Segmenting text into coherent and thematically consistent blocks

• Analyzing syntactic structures

Which term refers to the linguistic relationships within a text that create a sense of unity?

• Cohesion

• Discourse analysis

• Coherent

• Lexical ambiguity

In the context of discourse, what does a cohesion chain represent?

• The logical flow of ideas within a segment

• A sequence of linguistically connected elements in a text

• The frequency of terms in a document

• The syntactic complexity of sentences

Which measure is used to assess the importance of a term in a document relative to its frequency in a corpus?

• Lexical ambiguity

• Cohesion chain

• TF-IDF

• Cosine similarity

In TextTiling, what does a low depth score indicate at a potential boundary point?

• High coherence

• A topic shift

• Lexical ambiguity

• Low similarity
