Concepts in Information Science

In Information Science, it is important to be able to produce contextual elements that help make people understand the information conveyed to them. One of those methods for providing that context is through visual information from images. Images are a different beast when it comes to information retrieval. Usually, pending personal photo collections, images are publicly available. The method through which imagery is retrieved is called Content Based Image Retrieval. 

Content based Image Retrieval.

Linked Data Refers to a set of best practices for publishing and connecting data on the web. When the practice of linked data is applied to the World Wide Web it connects to various forms of data and acts as a interconnected search system for information retrieval. In addition, Linked Data is also comprised and complimented by the following:
- Rules for Linked Data
- Metadata
- Publishing Tools
- Data Browsers
- Human Oriented Search Engines
- Domain Specific Applications
- Microformats
- Web APIs
- Data Spaces

Information and the utilization of it has a start, but how did it become a Science practiced by Librarians as well as Information Professionals? It started off as a concept based on epistemological use in different languages and practices that define the original word of information to mean support or educate. From that, information begins to become a science based on historical innovations that create practices for it and expands its use. In understanding Information Science at a conceptual level, it can be defined and contextualized by its origins as well as where it is going.
