Which of the following tasks is not typically associated with Information Extraction?

• Named Entity Recognition (NER)

• Relation Extraction

• Document Classification

• Event Extraction

In Named Entity Recognition (NER), what does the task primarily involve?

• Classifying the entire document into predefined categories

• Identifying and classifying proper names within the text

• Extracting relationships between entities

• Summarizing the main points of a document

Which technique is commonly used for Relation Extraction?

• Term Frequency-Inverse Document Frequency (TF-IDF)

• Support Vector Machines (SVM)

• Hidden Markov Models (HMM)

• Dependency Parsing

Information Extraction systems typically require which type of data to function effectively?

• Unstructured data

• Structured data

• Semi-structured data

• Metadata

What is the primary goal of Information Retrieval?

• Extracting specific pieces of information from large datasets

• Summarizing the content of documents

• Finding relevant documents from a large collection based on a query

• Translating documents from one language to another

Which model is most commonly used in Information Retrieval?

• Boolean Model

• Vector Space Model

• Hidden Markov Model

• Naive Bayes Model

Which metric is often used to evaluate the performance of an Information Retrieval system?

• Precision

• Recall

• F1 Score

• All the above

Inverted indexes in Information Retrieval are used for:

• Document Classification

• Query Expansion

• Efficiently searching for documents containing specific terms

• Summarizing documents

What is the main difference between extractive and abstractive summarization?

• Extractive summarization generates new sentences, while abstractive summarization selects sentences directly from the text.

• Abstractive summarization generates new sentences, while extractive summarization selects sentences directly from the text.

• Extractive summarization involves translating the text, while abstractive summarization involves paraphrasing the text.

• There is no significant difference between the two.

Which method is commonly used in extractive summarization?

• Sentence ranking

• Sentence paraphrasing

• Language modeling

• Neural network translation
