Metadata subsystem for a distributed object store in a network storage system

Abstract: A network storage server system includes a distributed object store and a metadata subsystem. The metadata subsystem stores metadata relating to the stored data objects and allows data objects to be located and retrieved easily via user-specified search queries. It manages and allows searches on at least three categories of metadata via the same user interface and technique. These categories include user-specified metadata, inferred metadata and system-defined metadata. Search queries for the metadata can include multi-predicate queries.

Accessing media data using metadata repository

Abstract: A computer-implemented method includes receiving, in a computer system, a user query comprising at least a first term, parsing the user query to at least determine whether the user query assigns a field to the first term, the parsing resulting in a parsed query that conforms to a predefined format, performing a search in a metadata repository using the parsed query, the metadata repository embodied in a computer readable medium and including triplets generated based on multiple modes of metadata for video content, the search identifying a set of candidate scenes from the video content, ranking the set of candidate scenes according to a scoring metric into a ranked scene list, and generating an output from the computer system that includes at least part of the ranked scene list, the output generated in response to the user query.

Method and system for flexible workflow management

Abstract: A method for providing emergent and flexible workflow management to a user. The user communicates with other users, using a message-based system having embedded information management resources. The message-based system has a viewer. A message is generated at the message-based system. The message has metadata. The metadata of the message is updated using the embedded information management resources. The metadata include at least one of the group of a deadline, a reminder, a deferral and an obligation. The message is sent to the other users. Some of the metadata of the message are displayed on the viewer of the message-based system. Some of the metadata of the message are tracked at the message-based system.

CERMINE: automatic extraction of structured metadata from scientific literature

Abstract: CERMINE is a comprehensive open-source system for extracting structured metadata from scientific articles in a born-digital form. The system is based on a modular workflow, whose loosely coupled architecture allows for individual component evaluation and adjustment, enables effortless improvements and replacements of independent parts of the algorithm and facilitates future architecture expanding. The implementations of most steps are based on supervised and unsupervised machine learning techniques, which simplifies the procedure of adapting the system to new document layouts and styles. The evaluation of the extraction workflow carried out with the use of a large dataset showed good performance for most metadata types, with the average F score of 77.5 %. CERMINE system is available under an open-source licence and can be accessed at http://cermine.ceon.pl. In this paper, we outline the overall workflow architecture and provide details about individual steps implementations. We also thoroughly compare CERMINE to similar solutions, describe evaluation methodology and finally report its results.

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.
