- Category component
  A component that manages categorization and clustering.
- CFS
  Connector Framework Server. A component that processes the information that is retrieved by connectors. CFS uses File Content Extraction to extract document content and metadata from over 1000 different file types. When the information has been processed, it is sent to a Content component index or Distributed Index Handler (DIH).
- cluster
  A set of documents that Knowledge Discovery identifies as being related. Each cluster represents a concept area, which contains a set of items that share common properties. Clustering data allows you to make trends and developments in data visible.
- clustering
  The process of grouping documents into sets (clusters) that have related content. Each cluster represents a concept area, which contains a set of items that share common properties. Clustering data allows you to make trends and developments in data visible.
- Community component
  A component that manages users and communities.
- conceptual search
  A type of query that allows you to search for documents that match the concept that your query text defines, rather than matching the particular keywords in your text. See Also: query.
- connector
  A component (for example File System Connector) that retrieves information from a local or remote repository (for example, a file system, database, or Web site).
- Connector Framework Server
  See CFS.

- DIH
  Distributed Index Handler. A component that allows you to efficiently split and index extremely large quantities of data into multiple copies of the Content component. DIH allows you to create a scalable solution that delivers high performance and high availability. It provides a flexible way to batch, route, and categorize the indexing of internal and external content into the Content component.
- Distributed Action Handler
  See DAH.
- Distributed Index Handler
  See DIH.
- Document Security
  An integrated security solution to protect your data. At the front end, authentication checks that users are allowed to access the system that contains the result data. At the back end, entitlement checking and authentication combine to ensure that query results contain only documents that the user is allowed to see, from repositories that the user has permission to access. For more information, refer to the Document Security Administration Guide.
- dynamic thesaurus
  A type of automatic query guidance (AQG) that provides a list of similar terms and concepts for a particular query.
E
- entity
  In Named Entity Recognition, an entity is a word, phrase, or block of information that the Named Entity Recognition component can match and extract from documents. An entity can be a specific text string, such as a name, or it can be a pattern of text such as an address or phone number. You define the pattern in a grammar, which Named Entity Recognition uses to find the entities in documents.
- entity extraction
  see Named Entity Recognition
- explicit agent
  An agent that users explicitly create from themselves. See Also: agent, implicit agent
F
- field
  Fields define different parts of content in documents in the Knowledge Discovery index, such as the title, content, and metadata information.
- FieldText
  A type of query that searches for particular content in a particular document field. See Also: query, field
- File Content Extraction

G
- geospatial search
  A search for a location, based on coordinates. With appropriate content, Knowledge Discovery can search for a specific location, or locations in a particular area, or within a specified distance of a point.
- grammar
  In Named Entity Recognition, a grammar is a file that defines the entities that you want to extract. It can be a simple list of entiites, or a pattern that defines what the entity looks like. See Also: Named Entity Recognition, entity
H
- hyperlinks
  The ability for Knowledge Discovery to connect related documents to results, by using suggestions. See Also: suggest
I
- implicit agent
  An agent that is created as part of a user profile. When you profile a user, Knowledge Discovery creates these agents for a user, according to the documents and search results that the user views. See Also: agent, explicit agent
- Ingest
  Ingestion converts information that exists in a repository into documents that can be indexed. Ingestion starts when a connector finds new information in a repository, or information that has been updated or deleted. Ingestion includes file content extraction, and processing tasks that can modify and enrich the information in a document.
K
- keyframe
  The first frame following a significant scene change. Keyframes are often used as preview images for video clips.
- Knowledge Discovery
  A family of products that allow you to collect, ingest, index, and process unstructure, semi-structured and structured information from multiple sources and repositories.
L
- LDAP
  Lightweight Directory Access Protocol. Applications can use LDAP to retrieve information from a server. LDAP is used for directory services (such as corporate email and telephone directories) and user authentication. See also: active directory, primary domain controller.
- License Server
  License Server enables you to license and run multiple Knowledge Discovery solutions. You must have a License Server on a machine with a known, static IP address.
M
- mailing
  An automatic process for sending an email to users when new content is added to the Content component index that matches their agents or profiles. See Also: alerting
- mapped security
  A security setup where Connectors index documents into the Content component index with an encrypted access control list (ACL), which Knowledge Discovery uses to match user permissions for the document. With this method, Knowledge Discovery does not need to check the original data repository to check the security information every time a user attempts to access the document. See Also: ACL
- Media Server
  A component that analyzes video files and streams, image files, and audio to extract information about their content. Media Server can run analysis operations such as face recognition, number plate recognition, speech-to-text, and speaker identification.
N
- Named Entity Recognition
  The process of extracting entities (patterns of text) from documents.
- natural language question-answering
  The process of answering a question that is asked in normal speech-style language, rather than in query language. Answer Server can process natural language questions and return answers.
O
- OmniGroupServer
  A component that manages access permissions for your users. It communicates with your repositories and components to apply access permissions to documents.
P
- parametric search
  A type of query that returns a list of all possible values of a specified field for documents that match a particular standard query. You can use the values to find matching documents with a particular property. This process is also known as filtering or faceted search. Compare With: FieldText
- primary domain controller
  A server computer in a Microsoft Windows domain that controls various computer resources. See also: active directory, LDAP.
- profiles
  Information about a user that is based on the concepts in documents that the user reads. Every time a user opens a document, the Community component updates their profile. This process allows the administrator to bring new documents that match the interests in a user profile to the attention of the users.
- 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 Manipulation Server
  See QMS.
- 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.
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.
- 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.
S
- 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.
- sentiment analysis
  A form of Named Entity Recognition that identifies positive and negative sentiment in text.
- 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.
- 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.
- 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 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
- 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.
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.
