sökmodeller
Sökmodeller, or search models, are mathematical frameworks used to represent and understand the process of information retrieval in search engines. They are essential for organizing, storing, and accessing information efficiently. The primary goal of a search model is to match user queries with relevant documents from a large corpus. There are several types of sökmodeller, each with its own strengths and weaknesses.
The Boolean model is one of the earliest and simplest search models. It uses Boolean logic to
The Vector Space Model (VSM) represents documents and queries as vectors in a high-dimensional space. The similarity
The Probabilistic model, such as the BM25 model, assigns a probability score to each document based on
The Language model treats documents as samples from a probability distribution over words. It calculates the
Each sökmodell has its own advantages and limitations. The choice of model depends on factors such as
