Information Retrieval (IR) refers to the human-computer interaction (HCI) that happens when we use a machine to search a body of information for information objects (content) that match our search query. Depending on the programmed sophistication of the machine, a person's query is matched against a set of documents to find a subset of 'relevant' documents.
The programmed sophistication of the machine determines its efficiency in extraction or pulling out of 'relevant' content from large volumes of texts. For example, the machine's natural language processing, i.e. it's ability to 'understand' a person's information retrieval process, entails information extraction (IE). IE refers to the machine's ability to automatically extract structured information. IE of structured information relies on this basic content management principle: "Content must be in context to have value". Contextualised content is ontologically categorized and semantically well-defined data.

What are the difference between database systems and data information retrieval systems?
A database management system (DBMS or simply database) forms the back-end of a data information retrieval system. Data retrieval is just one component of a DBMS; data input, storage and maintenance being the other major components.
Difference between wisdom tooth extraction and surgery?
Extraction is numbing your area and pulling your tooth. Surgery is having incisions and usually be put out to get teeth out.
Extraction of erupted tooth or exposed root . Extraction surgical root. What is the difference between these two phrases?
what is the difference between a surgical tooth and a erupted toothExtraction of erupted tooth refers to the dentist physically pulling out the tooth due to whatever trauma it has undergone. Extraction of the root is going into the tooth and drilling out the roots, like a root canal.
Is there any difference between extraction of metals and electrolysis?
Yes, there is a difference between the extraction of metals and electrolysis. Extraction of metals refers to the various methods used to obtain metals from their ores, which can include pyrometallurgy (using heat) and hydrometallurgy (using aqueous solutions). Electrolysis, on the other hand, is a specific technique often used in the extraction process, particularly for reactive metals, where an electric current is passed through a molten or dissolved electrolyte to separate the metal from its ions. While electrolysis is one method of extraction, not all metal extraction processes involve electrolysis.
What is the difference between standard and cognitive interview?
A standard interview uses repetition free recall followed by specific questions. It does not help a witness retrieve information from memory. A cognitive interview is an effective method to aid retrieval of an Eyewitness account, recreates context, focuses concentration and will have multiple and varied retrieval attempts.
What is the difference between a portal and a directory?
A portal allows the information retrieval and data, disseminate from different resources. On the other hand, a directory is a subject monitor usually organized by major topics and subtopics. Directories usually contain portal sites.
What is the difference between Information Science and Communication Science?
Information Science focuses on the collection, organization, and retrieval of information, while Communication Science focuses on the study of human communication processes, including verbal and nonverbal communication. Information Science deals more with data management and technology, whereas Communication Science covers a broader range of topics related to communication theory and practice.
What is the methods of information Extraction?
Information extraction (IE) involves several methods, including named entity recognition (NER), which identifies and classifies key entities in text; relation extraction, which uncovers relationships between entities; and event extraction, which identifies and categorizes specific events mentioned in the text. Techniques may also include keyword extraction and semantic role labeling. These methods often utilize natural language processing (NLP) algorithms and machine learning models to automate the extraction of structured information from unstructured data.
What is the difference between memory and learning?
Memory is the ability to store and recall information, while learning is the process of acquiring new knowledge or skills. Memory involves retaining and retrieving information, while learning involves understanding and integrating new information into existing knowledge. In essence, memory is the storage and retrieval of information, while learning is the acquisition and assimilation of new knowledge.
What is difference between acre?

What is the purpose of the induction interface disk in the context of data storage and retrieval?
The purpose of the induction interface disk in data storage and retrieval is to facilitate the transfer of data between the storage device and the computer system. It helps in managing the flow of information, ensuring compatibility, and improving the efficiency of data access and retrieval processes.
What are the components of information retrieval system?
1. User, with goals, problem, task, knowledge2. Information resource; with information objects selected, organized and represented,3. Mediator, who helps to support the interaction between user and information resource
