An introduction to information retrieval: applications in genomics

Area of Science:

• Computer Science
• Bioinformatics
• Genomics

Background:

• Information retrieval (IR) is a computer science field focused on processing free-text documents for keyword-based retrieval.
• IR technology underpins web search engines and is crucial for biomedical literature search software.
• Document indexing can use keywords or concepts from domain-specific thesauri, though concept matching presents challenges.

Purpose of the Study:

• To provide an introduction to the field of Information Retrieval.
• To summarize the applications of IR and related technologies within the field of genomics.

Main Methods:

• Review and introduction to core Information Retrieval principles.
• Exploration of existing and potential applications of IR in genomics research.

Main Results:

• Information retrieval is fundamental to efficient data searching in computer science and biomedical research.
• While keyword matching is standard, concept matching in IR faces practical limitations for standalone use.
• The article outlines diverse applications of IR technologies specifically tailored for genomics.

Conclusions:

• Information retrieval is a foundational technology for accessing textual information, particularly in specialized domains like genomics.
• Understanding IR principles is essential for leveraging advanced search capabilities in scientific research.
• Future applications may benefit from improved methods addressing the limitations of concept-based retrieval in genomics.
