Types of Question Answering Models
Question answering models are increasingly becoming an integral part of learning and information retrieval. They can be classified into three main types: retrieval-based models, generative models, and knowledge-based models.
Retrieval-Based Models
Retrieval-based models, also known as information retrieval models, provide answers by searching through a predefined set of responses. They rank these responses based on their relevance to the input question and return the most appropriate one.
These models typically use methods like TF-IDF (Term Frequency-Inverse Document Frequency) or BM25 (Best Matching 25) to determine the relevance of a response. These methods measure how often a term appears in a document while accounting for the frequency of the term in the entire document collection.
The primary advantage of retrieval-based models is their ability to provide accurate and consistent responses. However, their scope is limited to the predefined responses, making them less flexible than generative models.
Generative Models
Generative models, on the other hand, can generate unique responses based on the input question. They don’t rely on a predefined set of responses. Instead, they use machine learning algorithms to understand the context of the question and generate an appropriate response.
Commonly used generative models include sequence-to-sequence (Seq2Seq) models and transformer models. These models can handle a wide range of questions and can provide detailed and context-aware responses.
However, generative models are more complex and computationally intensive than retrieval-based models. They also require large amounts of training data to perform well.
Knowledge-Based Models
Knowledge-based models use a structured knowledge base to provide answers. The knowledge base contains facts about the world, represented in a structured format. When a question is asked, the model searches the knowledge base for relevant facts and uses them to construct the answer.
These models excel at answering fact-based questions. However, they struggle with questions that require understanding of context or subjective opinions.
Each type of question answering model has its strengths and weaknesses. Depending on the specific needs and resources available, one might prefer one model over the others. Understanding these types is a critical step in leveraging AI-powered question answering for learning and information retrieval.
