What is information retrieval algorithms?
An Information Retrieval Algorithm is an information processing algorithm that can be applied by a IR system (to solve an IR task). AKA: IR Technique. Context: It can involve the conversion of a Document into a Document Vector. It can make use of a TF-IDF Ranking Function.
What is the main concept of information retrieval?
Information retrieval is intended to support people who are actively seeking or searching for information, as in Internet searching. Information retrieval typically assumes a static or relatively static database against which people search.
What is information retrieval process?

Current information is available in the storage database. Users can access multi-database to use multiple keywords/concepts at the same time.
What are the characteristics of information retrieval?
Twelve other characteristics of IR models are identified: search intermediary, domain knowledge, relevance feedback, natural language interface, graphical query language, conceptual queries, full-text IR, field searching, fuzzy queries, hypertext integration, machine learning, and ranked output.
