Faceted metadata for image search and browsing

Abstract: There are currently two dominant interface types for searching and browsing large image collections: keyword-based search, and searching by overall similarity to sample images. We present an alternative based on enabling users to navigate along conceptual dimensions that describe the images. The interface makes use of hierarchical faceted metadata and dynamically generated query previews. A usability study, in which 32 art history students explored a collection of 35,000 fine arts images, compares this approach to a standard image search interface. Despite the unfamiliarity and power of the interface (attributes that often lead to rejection of new search interfaces), the study results show that 90% of the participants preferred the metadata approach overall, 97% said that it helped them learn more about the collection, 75% found it more flexible, and 72% found it easier to use than a standard baseline system. These results indicate that a category-based approach is a successful way to provide access to image collections.

A distributed storage system for data-sharing among client computers running different operating system types

Abstract: A distributed data storage system for sharing data among client computers running different types of operating systems by separating metadata from data. Data is stored in storage pools that are accessed by the client computers through a storage network. Metadata is stored in a metadata store and provided to the client computers by a cluster of metadata servers. The client computers communicate with the metadata servers using a Storage Tank protocol and over a control network. Each client computer runs an operating system-specific client program that provides the client side functions of the Storage Tank protocol. The client program preferably includes a file system interface for communicating with the file system in the storage system and user applications, a client state manager for providing data consistency, and a plurality of operating system services for communicating with the metadata servers.

A Metadata Catalog Service for Data Intensive Applications

Abstract: Advances in computational, storage and network technologies as well as middle ware such as the Globus Toolkit allow scientists to expand the sophistication and scope of data-intensive applications. These applications produce and analyze terabytes and petabytes of data that are distributed in millions of files or objects. To manage these large data sets efficiently, metadata or descriptive information about the data needs to be managed. There are various types of metadata, and it is likely that a range of metadata services will exist in Grid environments that are specialized for particular types of metadata cataloguing and discovery. In this paper, we present the design of a Metadata Catalog Service (MCS) that provides a mechanism for storing and accessing descriptive metadata and allows users to query for data items based on desired attributes. We describe our experience in using the MCS with several applications and present a scalability study of the service.

Methods, systems, and computer-readable mediums for providing persisting and continuously updating search folders

Abstract: Providing persisting search folders within a computer that continuously identify data items having metadata matching a query of search criteria. A query of search criteria formulated via a graphical user interface is applied to a search filter to create a search folder. When the search folder is made live, the search filter is used to search one or more data stores for data items having metadata matching the query of search criteria. Upon finding these data items, the search folder is populated with a link to each data item having metadata matching the query of search criteria. The search folder detects when any new data items are added to a data store and when a change occurs to any metadata of data items previously stored in a data store. Upon detection, the search folders store links to matching new or changed data items.

Organization and maintenance of images using metadata

Abstract: Data for electronic images is stored in a server. Metadata is assigned to each image file and categorizes each image according to one or more schemes. Possible metadata schemes include image date, one or more image subjects, and image location. The image files may then be searched based on the assigned metadata. Images may be stored in a database that includes at least one virtual folder corresponding to each metadata scheme, with each image having at least one entry in each folder. Each folder may further have subfolders that correspond to sub-categories of a categorization scheme. Each image may then have an entry in each subfolder which describes a part of the image metadata. A date search interface allows a user to select a year of interest, then a month, and then a day. A location search interface allows a user to select a subregion of a displayed region.

OPeNDAP: Accessing data in a distributed, heterogeneous environment

Abstract: In the process of implementing a protocol for the transport of science data, the Open Source Project for a Network Data Access Protocol (OPeNDAP) group has learned a considerable amount about the internal anatomy of what are commonly considered monolithic concepts. In order to communicate among our group, we have adopted a collection of deinitions and observations about data and the metadata that make them useful: differentiating between "semantic" and "syntactic" metadata, and deining categories such as "translational" and "use" metadata. We share the deinitions and categorizations here in the hope that others will ind them as useful as we do.

Database system and a method of data retrieval from the system

Abstract: Metadata pertaining to real data stored in at least one database (DB) are collected and managed at a single meta DB server, and metadata that match a retrieval request are extracted by search of the meta DB server. Even when a plurality of DBs and DB servers for managing DBs are present on a network, all metadata that match the retrieval request can be extracted independently of the DBs that the metadata pertain to. Hence, all data that match a retrieval request can be obtained from a single server, independently of the actual locations of the distributed DBs and DB servers.

Multi-tiered structure for file sharing based on social roles

Abstract: An Internet-scale file sharing system includes a client-side file sharing application that allows file-sharing users to identify files to share and transmit metadata corresponding to those files to a metadata repository. A server-side application operating on the metadata repository tracks metadata received from associated file-sharing users, as well as metadata from other affiliated metadata repositories. Each metadata repository acts as a search engine for any querying users and can provide search results based on locally stored metadata alone. Each metadata repository may additionally choose to locally-store popular files from an associated file-sharing user so as to alleviate transmission burdens on that file-sharing user. Associated metadata repositories each periodically synchronize their stored metadata so that all metadata repositories may generate similar search results. In such manner, file-sharing queries need only be performed by the metadata repository receiving the query, and not by all associated metadata repositories.

From unstructured data to actionable intelligence

Abstract: There's content everywhere, but not the information you need. Content analysis can organize a pile of text into a richly accessible repository. This article explains two key technologies for generating metadata about content - automatic categorization and information extraction. These technologies, and the applications that metadata makes possible, can transform an organization's reservoir of unstructured content into a well-organized repository of knowledge. With metadata available, a company's search system can move beyond simple dialogs to richer means of access that work in more situations. Information visualization, for example, uses metadata and our innate visual abilities to improve access. Besides better access, metadata enables intelligent switching in the content flows of various organizational processes - for example, making it possible to automatically route the right information to the right person. A third class of metadata applications involves mining text to extract features for analysis using the statistical approaches typically applied to structured data. For example, if you turn the text fields in a survey into data, you can then analyze the text along with other data fields. All these metadata-powered applications can improve your company's use of its information resources.

Method of managing metadata

Abstract: Managing metadata in a metadata transmission server by generating a plurality of metadata fragment data by partitioning metadata to be transmitted based upon predetermined segment units, selecting predetermined metadata fragment data from among the plurality of the metadata fragment data, generating metadata-related authentication information using the selected metadata fragment data, and transmitting the selected metadata fragment data and the metadata-related authentication information including data format information indicating type of the selected metadata fragment data. A metadata receiving client uses the transmitted metadata fragment data, the metadata-related authentication information and the metadata format type information to authenticate the received metadata.

Visualization of semantic metadata and ontologies

Abstract: Implicit information embedded in semantic Web graphs, such as topography, clusters, and disconnected subgraphs is difficult to extract from text files. Visualizations of the graphs can reveal some of these features, but existing systems for visualizing metadata focus on aspects other than understanding the greater structure. We present a tool for generating visualizations of ontologies and metadata by using a modified spring embedder to achieve an automatic layout. Through a case study using a mid-sized ontology, we show that interesting information about the data relationships can be extracted through our visualization of the physical graph structure.

Methods, computer readable mediums and systems for requesting, retrieving and delivering metadata pages

Abstract: Methods, computer readable mediums and systems provide media player users with a full contextual metadata experience. Metadata include multiple forms of property data, or information, relating to media accessed by a media player, such as a CD in a CD-ROM drive of a computer. Metadata is transferred from a server to a client. Identification parameters associated with the accessed media file are submitted by the client to a server, and property data is retrieved and forwarded to the client. The metadata provides the user with integrated, contemporaneous property data directly related to the media file being played, providing automatic, integrated access to data from multiple databases, simply by accessing a related media file through a media player, without further direction from the user.
