TRavel and EXpense Reimbursement System

Methods for extracting information from natural-language texts.

An index server that manages original indexes. In a single host system the master index servers are responsible for searching and indexing. In a distributed TREX system the master index servers are re [..]

A name server that can read and update the topology of a TREX system. Master name servers can only be used in distributed TREX systems.

A web-based software application designed for the exchange of electronic student records as mandated by the 79th Legislature, 3rd Called Session, 2006 (House Bill 1).  By using the TREx application, s [..]

A queue server that manages parts of queues.

A TREX component that crawls file shares and Web sites for documents to be indexed by TREX.

Superordinate term for the TREX search engine, TREX text-mining engine, and TREX attribute engine.

A function of the TREX Monitor that is used to edit TREX INI files in order to modify the TREX configuration. This function is called from the TREX Administration area in SAP Enterprise Portal.

TREX component that offers standard retrieval functions such as exact and error-tolerant search, phrase search, Boolean search, and attribute search.

Service in the J2EE Engine that is used by an SAP application to access the search, text-mining, and classification functions of Search and Classification (TREX). The service is implemented as the TRE [..]

TREX component that offers text-mining functions such as classification, searching for similar documents, and feature extraction.

TREX-specific communication protocol that is based on TCP/IP. Certain TREX components use TREXNet to communication with each other. TREXNet can be configured for secure communication.

A data transfer method that uses a queue mechanism for creating document information in a retrieval system.

TREX component that enables searching for document attributes such as author, creation date, or change date.

Index of the TREX attribute engine. This index is used for searching in document attributes such as author, creation date, and modification date.

Search that retrieves documents whose properties (metadata) match the properties in the search query. Attribute-based search of meta-data and full-text search of content can be combined.

A host that is running a backup index server.

An index server that can replace the master index server if it breaks down. Backup index servers are only used in distributed TREX systems.

A queue server that can replace a master queue server if it breaks down.Backup queue servers can only be used in distributed TREX systems.

Concept that figures as a node in a hierarchy of concepts (taxonomy) used for grouping documents based on their content.

Content-based (semi-) automatic assignment of documents to one or more categories of a taxonomy. The categories to which a document was assigned are stored as properties of the document.

Index that consists of more than one table index and metadata. It allows users to search for structured data that is spread over more than one table index.

One of the procedures for assigning documents to the categories of a taxonomy. For query-based classification, this assignment takes place using search queries that are defined for the individual cate [..]

Taxonomy for which the content of categories is determined using search requests.

Specifies how well a document matches a search query or how well a documents fits into a category.

A file containing error messages that the index server, name server, preprocessor, queue server, and Web server return during routine operation of the system

The route to take to display trace files.

Document that belongs to a document set used for training a taxonomy. Training documents help the text mining engine to learn which features are typical of individual categories in a taxonomy.

The process of sending the details of a document to be indexed to the preprocessor.

Index that exists only in the main memory and makes available all standard TREX functions.

The search engine service allows you to search for business objects using search engine technology. Its service characteristics include:

KM functions and services for finding information and classifying documents.

TREX component that offers standard search functions including exact search, error-tolerant search, linguistic search, Boolean search, and phrase search.

Retrieval method used when executing a search query. Users can choose among different search modes, for example, exact search, linguistic search, etc.

A host that is running a slave index server.

A copy of a master index that is generated during index replication and assigned to a slave index server.

An index server that manages index copies. Slave index servers are only used in distributed TREX systems. They are only responsible for searching - not for indexing.

A name server that can read the topology of a TREX system but cannot update it. Slave name servers are only used in distributed TREX systems.

TREX component that offers text-mining functions such as classification, search for similar documents, and key word extraction.

Index of the TREX text-mining engine. This index is used for text-mining functions such as classification, searching for similar documents, and extracting keywords.

Index for which the content comes from a database table.

An original index.

A host that is running a master index server.

The process of crawling a collection of documents step-by-step.

Program that finds large collections of documents.

The removal of a document's representation from an index.

An optional part of an index. If the delta index is activated, index changes are made in the delta index rather than the main index. This speeds up the updating of the index because the delta index is [..]

Search method that only retrieves documents containing terms that literally match the search terms specified in the query.

One of the procedures for assigning documents to the categories of a taxonomy. With example-based classification, this assignment takes place through the comparison of example documents. Example-based [..]

Taxonomy for which the content of the categories is determined using example documents.

Identification of characteristic terms for a document or a collection documents.

Search across multiple indexes that were created by multiple search engines.

Index of the TREX search engine. This index is used for standard search functions such as exact search, error-tolerant search, and linguistic search. A pure search index can not be used for text-minin [..]

Search on an index that contains all words that occur in the indexed documents instead of only abstracts or other metadata.

(Degree of) similarity required between a document and the search query for the document to be returned in the result set of a fuzzy search.

A search method that finds linguistic variants of search terms as well as exact instances.

The storage of document information in a retrieval system.

The technical name of the index used to identify it in the system.

A copy of a master index that is generated when index replication takes place. TREX uses index snapshots to determine which of the changes to the master index have to be transferred to the slave index [..]

Only relevant when Retrieval and Classification (TREX) is implemented outside the Enterprise Portal.

Direct data transfer for storing document information in a retrieval system.
