Schema mappings, data exchange, and metadata management

Abstract: Schema mappings are high-level specifications that describe the relationship between database schemas. Schema mappings are prominent in several different areas of database management, including database design, information integration, data exchange, metadata management, and peer-to-peer data management systems. Our main aim in this paper is to present an overview of recent advances in data exchange and metadata management, where the schema mappings are between relational schemas. In addition, we highlight some research issues and directions for future work.

Auto playlist generator

Abstract: A system and method for generating a list is provided. The system includes a seed item input subsystem, an item identifying subsystem, a descriptive metadata similarity determining subsystem and a list generating subsystem that builds a list based, at least in part, on similarity processing performed on seed item descriptive metadata and user item descriptive metadata and user selected thresholds applied to such similarity processing. The method includes inexact matching between identifying metadata associated with new user items and identifying metadata stored in a reference metadata database. The method further includes subjecting candidate user items to similarity processing, where the degree to which the candidate user items are similar to the seed item is determined, and placing user items in a list of items based on user selected preferences for (dis)similarity between items in the list and the seed item.

Metadata brokering server and methods

Abstract: Exemplary embodiments of the present invention provide methods and systems for supplying rich multimedia metadata usable to generate, e.g., sophisticated entertainment user interfaces in the home. These methods and systems can be implemented as a server-based software application that feeds multiple, diverse clients. The server functionality could be distributed, even co-located physically with one or more clients, or centralized. The server aggregates, filters, validates, augments and links metadata from disparate sources. The server transforms the metadata into a more manageable and extensible internal format. The server communicates with client devices using a schema-independent protocol, providing metadata in the appropriate format that suites the clients needs.

A method and system for organizing items

Abstract: An organisation system (5) for organizing items (11), the system (5) comprising: a data structure (10) associating at least one semantic metadata (12) with an item (11) to define a directional relationship between a concept and the item (11); and a user interface (20) to express the at least one semantic metadata (12) in at least one natural language using a description or at least one keyword corresponding to the concept in the at least one natural language; wherein the at least one semantic metadata (12) corresponds to the concept that is a characteristic of the item (11); and the at least one semantic metadata (12) and the item (11) are referenced by unique machine-readable identifiers

Automating metadata generation: the simple indexing interface

Abstract: In this paper, we focus on the development of a framework for automatic metadata generation. The first step towards this framework is the definition of an Application Programmer Interface (API), which we call the Simple Indexing Interface (SII). The second step is the definition of a framework for implementation of the SII. Both steps are presented in some detail in this paper. We also report on empirical evaluation of the metadata that the SII and supporting framework generated in a real-life context.

Metadata management for fixed content distributed data storage

Abstract: An archival storage cluster of preferably symmetric nodes includes a metadata management system that organizes and provides access to given metadata, preferably in the form of metadata objects. Each metadata object may have a unique name, and metadata objects are organized into regions. Preferably, a region is selected by hashing one or more object attributes (e.g., the object's name) and extracting a given number of bits of the resulting hash value. The number of bits may be controlled by a configuration parameter. Each region is stored redundantly. A region comprises a set of region copies. In particular, there is one authoritative copy of the region, and zero or more backup copies. The number of backup copies may be controlled by a configuration parameter. Region copies are distributed across the nodes of the cluster so as to balance the number of authoritative region copies per node, as well as the number of total region copies per node. Backup region copies are maintained synchronized to their associated authoritative region copy.

DCMI Abstract Model

Abstract: This document specifies an abstract model for DCMI metadata [DCMI]. The primary purpose of this document is to provide a reference model against which particular DC encoding guidelines can be compared. To function well, a reference model needs to be independent of any particular encoding syntax. Such a reference model allows us to gain a better understanding of the kinds of descriptions that we are trying to encode and facilitates the development of better mappings and translations between different syntaxes. This document is primarily aimed at the developers of software applications that support Dublin Core metadata, people involved in developing new syntax encoding guidelines for Dublin Core metadata and those people developing metadata application profiles based on the Dublin Core.

Scoped access control metadata element

Abstract: Methods, systems, and data structures for communicating object metadata are provided. A generic metadata container is presented that allows object metadata to be described in an extensible manner using protocol-neutral and platform-independent methodologies. A metadata scope refers to a dynamic universe of targets to which the included metadata statements correspond. Metadata properties provide a mechanism to describe the metadata itself, and metadata security can be used to ensure authentic metadata is sent and received. Mechanisms are also provided to allow refinement and replacement of metadata statements. The generic metadata container can be adapted to dynamically define access control rights to a range of objects by a range of users, including granted and denied access rights.

Understanding Metadata and Metadata Schemes

Abstract: SUMMARY Although the development and implementation of metadata schemes over the last decade has been extensive, research examining the sum of these activities is limited. This limitation is likely due to the massive scope of the topic. A framework is needed to study the full extent of, and functionalities supported by, metadata schemes. Metadata schemes developed for information resources are analyzed. To begin, the author presents a review of the definition of metadata, metadata functions, and several metadata typologies. Next, a conceptualization for metadata schemes is presented. The emphasis is on semantic container-like metadata schemes (data structures). The last part of this paper introduces the MODAL (Metadata Objectives and principles, Domains, and Architectural Layout) framework as an approach for studying metadata schemes. The paper concludes with a brief discussion on the value of frameworks for examining metadata schemes, including different types of metadata schemes.

Image and other analysis for contextual ads

Abstract: The subject invention provides a unique system and method that facilitates providing contextual advertisements based on one or more identified terms extracted from a non-text object such as an image, video, and/or audio object. Terms can also be identified and extracted from metadata associated with or other data derived from text objects such as email messages and attached text documents. One or more recognition techniques can be employed to identify data found in the non-text object (including the metadata or any other data derived therefrom) and data found in the metadata associated with the text object. Once the identified terms are analyzed, an appropriate contextual advertisement can be presented to the user. If the content of the non-text or text object is deemed of a negative nature, no contextual advertisement is provided.

Method and apparatus for harvesting file system metadata

Abstract: A harvester is disclosed for harvesting metadata of managed objects (files and directories) across file systems which are generally not interoperable in an enterprise environment. Harvested metadata may include 1) file system attributes such as size, owner, recency; 2) content-specific attributes such as the presence or absence of various keywords (or combinations of keywords) within documents as well as concepts comprised of natural language entities; 3) synthetic attributes such as mathematical checksums or hashes of file contents; and 4) high-level semantic attributes that serve to classify and categorize files and documents. The classification itself can trigger an action in compliance with a policy rule. Harvested metadata are stored in a metadata repository to facilitate the automated or semi-automated application of policies.

Metadata management and generation using digital watermarks

Abstract: The present invention provides methods and systems to improve network searching for watermarked content. In some implementations we employ keyword searching to narrow the universe of possible URL candidates. A resulting URL list is searched for digital watermarking. A system is provided to allow customer input. For example, a customer enters keywords or network locations. The keywords or network locations are provided to a watermark-enabled web browser which accesses locations associated with the keywords or network locations. Some implementations of the present invention employ a plurality of distributed watermark-enabled web browsers. Other aspects of the invention provide methods and system to facilitate desktop searching and automated metadata gathering and generating. In one implementation a digital watermark is used to determine whether metadata associated with an image or audio file is current or fresh. The metadata is updated when it is out of date. Watermarks can also be used to link to or facilitate so-called on-line “blogs” (or online conversations).

Method and a system for responding locally to requests for file metadata associated with files stored remotely

Abstract: A method and system for responding locally to requests for file metadata associated with files stored remotely includes a method of responding locally to requests for file metadata without downloading the file from a remote location. A directory structure representing an application program stored by a remote machine and metadata associated with each file comprising the stored application program are received from the remote machine. The directory and the metadata are stored. At least one request to access metadata associated with a specific tile in the directory structure is received. The stored metadata is used to respond to the at least one request.

Generation of metadata for acquired images

Abstract: A method and image data acquisition service arrangement are disclosed that facilitate standardizing the process of adding metadata to acquired image information downloaded from a connected image capture device to a computer system. An image acquisition service analyzes image information downloaded from the image capture device and renders new metadata values based upon applied analytical algorithms/filters. Thereafter, the image information and new metadata are rendered available to other processes that use the image information and new metadata.

Activity based metadata for semantic desktop search

Abstract: With increasing storage capacities on current PCs, searching the World Wide Web has ironically become more efficient than searching one's own personal computer. The recently introduced desktop search engines are a first step towards coping with this problem, but not yet a satisfying solution. The reason for that is that desktop search is actually quite different from its web counterpart. Documents on the desktop are not linked to each other in a way comparable to the web, which means that result ranking is poor or even inexistent, because algorithms like PageRank cannot be used for desktop search. On the other hand, desktop search could potentially profit from a lot of implicit and explicit semantic information available in emails, folder hierarchies, browser cache contexts and others. This paper investigates how to extract and store these activity based context information explicitly as RDF metadata and how to use them, as well as additional background information and ontologies, to enhance desktop search.

Is 'Quality' Metadata 'Shareable' Metadata? The Implications of Local Metadata Practice on Federated Collections

Abstract: Introduction The federation of digital resources has become increasingly important in realizing the full potential of digital libraries. Federation is often achieved through the aggregation of descriptive metadata, therefore the decisions resource developers make for the creation, maintenance, and quality assurance of their metadata can have significant impacts on aggregators and service providers. Metadata may be of high quality within a local database or web site, but when it is taken out of this context, information may be lost or its integrity may be compromised. Maintaining consistency and fitness for purpose are also complicated when metadata are combined in a federated environment. A fuller understanding of the criteria for high quality, “shareable” metadata is crucial to the next step in the development of federated digital libraries. This study of metadata quality was conducted by the IMLS Digital Collections and Content (DCC) project team (http://imlsdcc.grainger.uiuc.edu/) using quantitative and qualitative analysis of metadata authoring practices of several projects funded through the Institute of Museum and Library Services (IMLS) National Leadership Grant (NLG) program. We present a number of statistical characterizations of metadata samples drawn from a large corpus harvested through the Open Archives Initiative (OAI) Protocol for Metadata Harvesting (PMH) and interpret these findings in relation to general quality dimensions and metadata practices that occur at the local level. We discuss the impact of these kinds of quality on aggregation and suggest quality control and normalization processes that may improve search and discovery services at the aggregated level.

Method and system for conversion of automation test scripts into abstract test case representation with persistence

Abstract: A general technique using semantic analysis is provided that can be used for converting a specific automation test script (and its underlying test case), generated from generally available or proprietary test automation tools, into an abstract test case representation. The abstract test case representation is based on a test case representation model that includes application states (state information), external interaction sequences (control flow information) and input data. The abstract representation in essence provides a platform independent representation of test cases. An application object model provides the representational capabilities required for capturing structural and behavioral properties of the application under test. The abstract test case representation can be validated against and further enriched by specific object information from an application metadata repository. Finally, object information and input data can be separated from control flow information to provide automatic parameterization of the test script.

System and method for creating and utilizing metadata regarding the structure of program content stored on a DVR

Abstract: Metadata regarding program content is created by monitoring a manner in which a first rendering of the program content is affected by a user whereupon the metadata will include data which defines one or more segments within the program content. The data within the metadata is then usable during a second rendering of the program content to inhibit, e.g., advance over during playing or omit during copying, the rendering of the one or more segments within the program content defined by the data within the metadata.

Inverse search systems and methods

Abstract: Inverse search systems and methods operate on identifiers of content items in a corpus such as the World Wide Web In an inverse search, the user submits a query that includes an identifier of a target content item in the corpus and receives information (metadata) about the target content item being returned to the user. Many types of metadata can be returned, including ratings or other metadata related to the target content item obtained from users, popularity data specific to the target content item, information about previously submitted forward search queries that led to the target content item being identified as a hit, and metadata extracted from the target content item.

Method of providing selected content items to a user

Abstract: A method is disclosed for providing selected content items to a user; the selection of content items is based on metadata pre-assigned to content items, typically authored content metadata, and on metadata generated and associated afterwards, called derived content metadate; additionally, the selection of content items can be based also on context metadata, particularly derived context metadata. Derived metadata are automatically generating on the basis of derivation rules corresponding to algorithms to be applied to e.g. the content of content items, authored content metadata and context metadata. User profiles can be used for improving the selection quality; a method is also disclosed for building and maintaining user profiles based on machine learning techniques.

Certain embodiments involve externalizing a metadata representation of a source data integration job; parsing the metadata representation; importing the parsed metadata into a plurality of object representations of the source data integration job; generating an intermediate representation of the source data integration platform based on the plurality of object representations; and translating the intermediate representation to generate a target data integration job; wherein the target data integration job is adapted perform substantially the same functions as the source data integration job.

Method and system for transferring information

Abstract: A method and system for application-to-application data exchange which provides data conversion from the format of a source application to the format of a target application upon receipt of data by the target application. To achieve compatibility among applications exchanging data, the preferred system uses a standard set of terms and process names for building metadata packets that inform both applications as to their respective data representation. A metadata packet includes a standard name and application specific data format, as well as an optional associated process name. Source metadata provided in connection with source application-specific data enables the conversion of the source format to the format compatible with the target. This method eliminates data conversion at the source application.

Ontology metadata vocabulary and applications

Abstract: Ontologies have seen quite an enormous development and application in many domains within the last years, especially in the context of the next web generation, the Semantic Web. Besides the work of countless researchers across the world, industry starts developing ontologies to support their daily operative business. Currently, most ontologies exist in pure form without any additional information, e.g. authorship information, such as provided by Dublin Core for text documents. This burden makes it difficult for academia and industry e.g. to identify, find and apply – basically meaning to reuse – ontologies effectively and efficiently. Our contribution consists of (i) a proposal for a metadata standard, so called Ontology Metadata Vocabulary (OMV) which is based on discussions in the EU IST thematic network of excellence Knowledge Web and (ii) two complementary reference implementations which show the benefit of such a standard in decentralized and centralized scenarios, i.e. the Oyster P2P system and the Onthology metadata portal.

System and method of handling file metadata

Abstract: A network storage system comprises data storage, one or more file system APIs, and a metadata handler. The data storage can comprise file data and associated metadata. The file system APIs can be configured to read and write file data and metadata to and from the data storage. The metadata handler can have a library of functions for handling the metadata. The library can include a metadata blob creation function and a metadata blob extraction function. The metadata blob creation function cooperates with the file system APIs to read source metadata associated with specified file data and creates and populates a metadata blob from which a substantial copy of the source metadata can be generated. The metadata blob extraction function receives at least a metadata blob, extracts information from the metadata blob, and cooperates with the file system APIs to generate destination metadata, a substantial copy of the source metadata.

Information intelligence: metadata for information discovery, access, and integration

Abstract: Integrating enterprise information requires an accurate, precise and complete understanding of the disparate data sources, the needs of the information consumers, and how these map to the semantic business concepts of the enterprise. We describe how MetaMatrix captures and manages this metadata through the use of the OMG's MOF architecture and multiple domain-specific modeling languages, and how this semantic and syntactic metadata is then used for a variety of purposes, including accessing data in real-time from the underlying enterprise systems, integrating it, and returning it as information expected by consumers.
