- index action
  A command to index data, or to maintain and manipulate the data index.
- index fields
  Fields that the Content component processes linguistically when it stores them. Store fields that contain text that you want to query frequently as Index fields. Content applies stemming and stop word lists to text in Index fields before it stores them, which allows Content to process queries for these fields more quickly.Typically DRETITLE and DRECONTENT are fields that are set up as Index fields.
- indexing
  The process of storing data in the Content component. Content stores data in different field types (such as index, numeric, and ordinary fields). It is important to store data in appropriate field types to ensure optimized performance.

This process allows the administrator to bring new documents that match the interests in a user profile to the attention of the users.
- promotions
  Targeted content that you want to display to users but that is not included in the search results, such as advertisements.
- Proxy component
  A component that accepts incoming actions and distributes them to the appropriate subcomponent. Proxy also performs some maintenance operations to make sure that the subcomponents are running, and to start and stop them when necessary.
Q
- QMS
  A component that modifies user queries and manipulates the results, for example to return promotions, remove particular query terms, or add synonyms.
- query
  A text string that you submit to the Content component, which analyzes the concept of the query text and returns documents that are conceptually similar to it. You can submit queries to Content to perform several kinds of search, such as natural language, Boolean, bracketed Boolean, and keyword.

- query summary
  A query operation that determines the important topics and phrases in a set of documents. Query summaries are used in Automatic Query Guidance (AQG). See Also: AQG.
- quick summary
  A brief summary of each result document that returns for a query. The quick summary displays the first few sentences of the result document.
R
- redaction
  The process of removing sensitive content from output. Knowledge Discovery supports text redaction through Named Entity Recognition, and face redaction in Media Server.
- reference
  A string that is used to identify a document. This might be a title or a URL, and allows the Content component to identify documents for retrieval, indexing, and deduplication.
- ReferenceType field
  Fields used to identify documents. At index time the Content component can use ReferenceType fields to eliminate duplicate copies of documents. It uses them at query time to filter results.
- relevance
  The similarity that a particular query result has to the initial query. The Content component assigns results a percentage relevance score according to how closely it matches the query criteria.
- retrain
  The process used to increase the accuracy of agents by indicating which of the results that return to you are most relevant to your query. The retrained agent then returns more relevant results.
- rich media analytics
  The ability to analyze audio, images, and videos for additional value and information, such as speech to text, optical character recognition (OCR), face recognition and identification, and object classification.
- role
  A set of privileges that an administrator can allocate to a Community component user.
S
- Search Optimizer
  Part of the Data Admin application that allows you to manage Knowledge Discovery content.
- section breaking
  The process of separating long documents into multiple sections for indexing. The number of sections increases in proportion to the size of the document. This process ensures that when you, for example, query for text that is relevant to a specific part of a book, the Content component can find the appropriate section and return it. If the book was not indexed in sections, Content might not find the text you searched for, because it might not be conceptually relevant to the entire book.
- sectioning
  See section breaking.
- security
  Security includes anything that makes sure that only authorized users can access or perform actions on data. It includes making sure that only permitted users can view and retrieve documents, user authentication, and secure communications.
- seed
  In clustering with snapshots, a seed is a potential cluster. It contains a document, and suggested conceptually similar documents from the index.
- sentiment analysis
  A form of Named Entity Recognition that identifies positive and negative sentiment in text.
- snapshot

- soundex
  A query type that allows you to search for a term by using a phonetic spelling.
- soundex search
  A type of query that allows you to search for a term by using a phonetic spelling.
- spectrograph
  A graphical representation of the results of clustering. The spectrograph displays clusters of documents, and the similarities between different clusters.
- spidering
  The process that Connectors use to retrieve content from Web resources, by recursively following hyperlinks from an initial page.
- stemming
  The process of extracting the morphological root of a word. In languages, some words have a common root. The Content component includes stemming algorithms that reduce words to this form. This process allows Content to match concepts regardless of the grammatical use of words. In English, for example, the words 'help', 'helpful', 'helping', and 'helped' all reduce to their stem 'help' without significant loss of meaning.
- stop word
  A very common word that occurs too frequently to be useful for searching. Stop words include articles (for example, the) and prepositions (for example, to or from). Stop words are language-specific. You can use a stop word list to allow the Content component to discard these words at index and query time to save index space and improve retrieval performance.
- stop word list
  Also called stop list. A list (located in the Content component langfiles directory) that contains common words (stop words) that Content does not store. Words such as the, and, or a occur too frequently to carry any significance, and Content does not require them to understand the concept of the text.
- stopping
  The process of removing the words listed in the stop word list from documents before they are stored in the Content component, and from query text before it is matched against indexed content.
- stored state
  A set of query results, which is stored in the Content component for you to re-use later in other operations. When you store a state, Content provides a state token, which you can use to retrieve the stored state.
- subfile
  A file that has been extracted from a container (such as a .ZIP archive)
- suggest
  A type of query that returns documents that contain similar concepts to a particular document, rather than matching a particular query string. See Also: query
- summary
  A few sentences or paragraphs that describe what a document is about. Knowledge Discovery can automatically create summaries from document content.
- synonym file
  A file that allows the Content component to handle synonym queries. A synonym query returns results which are conceptually similar to the query terms, and conceptually similar to the synonyms that are available for the query terms. A synonym file contains comma-separated lists of synonym strings for words. You can specify lists for each language type that you have set up in the Content component in this file.
- synonym search
  A type of query that returns documents that contain synonyms for a particular search term, as well as documents that contain the exact term. See Also: query
T
- tagging
  The process of adding extra information to documents. The tag might be a category, or entities returned from Named Entity Recognition. Tagging usually adds a field to a document, which you can use to search by the name of a tag.
- taxonomy
  An automatically created hierarchical structure of clusters or other information. A taxonomy provides you with an overview of the information landscape, and an insight into specific areas of the information.
- term
  The basic entity that the Content component indexes (for example, a word in a document after it has been stemmed).
- Terms and Weights.
  See TNW.
- TNW
  Terms and Weights. These values are used in categorization to define the most important terms that define a category topic.
- training
  Text, documents, and query syntax used to define the topic that an agent or category must match.
U
- Universal Query Language.
  See UQL.
- unmapped security
  A security setup where Knowledge Discovery checks the security entitlement of a user against the original data repositories in real time when the user attempts to access a document. With this method, Knowledge Discovery always has the current security information, but the response can be slow because of the additional connection to the repository. Compare With: mapped security
- UQL
  Universal Query Language. A name for the Content component query syntax, which you can use for keyword, conceptual, Boolean, and Wildcard searches.
V
- View
  A component that converts files in a repository to HTML formats for viewing in a Web browser.
W
- Wildcard
  A character that stands in for any character or group of characters in a query.
X
- XML
  Extensible Markup Language. XML is a language that defines the different attributes of document content in a format that can be read by humans and machines. In Knowledge Discovery, you can index documents in XML format. Knowledge Discovery can also return action responses in XML format.
