Wikipedia:Set index articles, list articles about a set of items of a specific type that also share the same (or similar) name. Similar to a WP:Disambiguation page but with actual content instead of just listing pages with the content.
In computer science, a lookup table (LUT) is an array that replaces runtime computation of a mathematical function with a simpler array indexing operation, in a process termed as direct addressing. The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an "expensive ...
A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time said table is accessed.
1 star: data is openly available in some format. 2 stars: data is available in a structured format, such as Microsoft Excel file format (.xls). 3 stars: data is available in a non-proprietary structured format, such as Comma-separated values (.csv). 4 stars: data follows W3C standards, like using RDF and employing URIs.
The index is similar to the term document matrices employed by latent semantic analysis. The inverted index can be considered a form of a hash table. In some cases the index is a form of a binary tree, which requires additional storage but may reduce the lookup time.
In computer science, an inverted index (also referred to as a postings list, postings file, or inverted file) is a database index storing a mapping from content, such as words or numbers, to its locations in a table, or in a document or a set of documents (named in contrast to a forward index, which maps from documents to content).

Uniterm is based on the concept of making a separate card catalog that refers to the documents in the collection by their accession numbers.The accession numbers have no meaning in the Uniterm index, so they may use any of the common systems like the Dewey Decimal Classification or Universal Decimal Classification, or in many cases, simply an incrementing serial number.
Subject indexing is used in information retrieval especially to create bibliographic indexes to retrieve documents on a particular subject. Examples of academic indexing services are Zentralblatt MATH, Chemical Abstracts and PubMed. The index terms were mostly assigned by experts but author keywords are also common.
