What is Information Retrieval ?
• The process of actively seeking out information relevant to a topic of interest (van Rijsbergen)
– Typically it refers to the automatic (rather than manual) retrieval of documents
• Information Retrieval System (IRS)
– “Document” is the generic term for an information holder (book, chapter, article, webpage, etc)
IR in practice
• Information Retrieval is a research-driven theoretical and experimental discipline
– The focus is on different aspects of the information–seeking process, depending on the researcher’s background or interest:
• Computer scientist – fast and accurate search engine
• Librarian – organization and indexing of information
• Cognitive scientist – the process in the searcher’s mind
• Philosopher – Is this really relevant ?
• …
– Progress influenced by advances in Computational Linguistics, Information Visualization, Cognitive Psychology, HCI, …
• Experimental vs. operational systems
• Analogy to car manufacturing
Fundamental concepts in IR
• What is information ?
• Meaning vs. form
• Data vs. Information Retrieval
• Relevance
Disclaimer
• Relevance and other key concepts in IR were discussed in the previous class, so we won’t do it again.
– We’ll take a simple view: a document is relevant if it is about the searcher’s topic of interest
• We will discuss text documents, not other media
– Most current tools that search for images, video, or other media rely on text annotations
– Real content retrieval of other media (based on shape, color, texture, …) are not mature yet
