e-Discovery Core Glossary: Terminology
Below is a list of terminologies that are necessary for legal professionals involved with e-Discovery and Discovery litigation support.O………………………………………………………………………………………………….....
OCR (Optical Character Recognition) A technology process that translates and converts printed matter on an image into a format that a computer can manipulate and, therefore, renders that matter text searchable. OCR software evaluates scanned data for shapes it recognizes as letters or numerals. All OCR systems include an optical scanner for reading text, and software for analyzing images. Most OCR systems use a combination of hardware (specialized circuit boards) and software to recognize characters, although some inexpensive systems operate entirely through software. Advanced OCR systems can read text in a large variety of fonts, but still have difficulty with handwritten text. OCR technology relies upon the quality of the imaged material, the conversion accuracy of the software, and the quality control process of the provider. The process is generally acknowledged to be between 80 and 99 percent accurate.
OffLine Data The storage of ESI outside the network in daily use that is only accessible through the offline storage system, not the network.
OffLine Storage ESI maintained or archived on removable disc (optical, compact, etc.) or magnetic tape used for making disaster recovery copies of records for which retrieval is unlikely. Accessibility to offline media usually requires manual intervention and is much slower than online or near line storage depending on the storage facility. The major difference between near line data and offline data is that offline data lacks an intelligent disc subsystem, and is not connected to a computer, network, or any other readily accessible system.
OnLine Review The culling process produces a dataset of potentially responsive documents that are then reviewed for a final selection of relevant or responsive documents and assertion of privilege exception as appropriate. Online Review enables the culled dataset to be accessed via PC or other terminal device via a local network or remotely via the Internet. Often, the OnLine Review process is facilitated by specialized software that provides additional features and functions which may include: collaborative access of multiple reviewers, security, user logging, search and retrieval, document coding, redaction, and privilege logging.
OnLine Storage The storage of ESI as fully accessible information in daily use on the network or elsewhere.
Ontology A collection of categories and their relationships to other categories and to words. Ontology is one of the methods used to find related documents when given a specific query.
OS (Operating System) An interface between hardware and user, which is responsible for the management and coordination of activities and the sharing of the resources of a computer that acts as a host for computing applications run on the machine. One of the purposes of an operating system is to handle the resource allocation and access protection of the hardware. This relieves the application programmers from having to manage these details.
Optical Discs Computer media similar to a compact disc that cannot be rewritten. An optical drive uses a laser to read the ESI.
Overinclusive When referring to data sets returned by some method of query, search, filter or cull, results that are returned overly broad.
