TL;DR: In this article, the authors propose a semi-automated method for the transformation or reconciliation of metadata from one form into another, which includes identifying data elements and their associated metadata in electronic file(s), transforming this metadata into an intermediate metadata format for later use in production of new metadata structure(s).
Abstract: An exemplary method for the automated, or semi-automated, conversion or reconciliation of metadata from one form into another, includes one or more of: a) identifying data elements and their associated metadata in electronic file(s); b) transforming this metadata into an intermediate metadata format for later use in production of new metadata structure(s); c) developing bodies of re-usable rules for the transformation or mapping of data sets encoded using one set of metadata into another data set encoded using a different set of metadata; d) developing bodies of re-usable metadata sets and rules for the transformation or mapping of metadata into an intermediate metadata structure; e) developing of bodies of re-usable metadata sets and rules for the transformation or mapping of metadata of an intermediate metadata structure into new metadata structure(s); and f) an efficient method for capture of conversion and validation rules.

TL;DR: A method and system for improving the quality of original metadata associated with media on a computer network, such as multimedia and streaming media, includes analyzing each field of the URL as mentioned in this paper.
Abstract: A method and system for improving the quality of original metadata associated with media on a computer network, such as multimedia and streaming media, includes analyzing each field of the URL of the multimedia and streaming media. Each field is analyzed to identify new metadata associated with that field. Identified new metadata is added to the original metadata. In another embodiment, the fields in the URL are reorganized in reverse order and metadata associated with a prefix of fields of the reorganized URL is added to the original metadata. In yet another embodiment, the contents of the field next to the prefix of fields is used to improve the quality of the original metadata.

TL;DR: This work presents an approach where semantic metadata is generated as scientific data is being prepared, and then subsequently used to configure models and to customize them to the data, generating more accurate results.
Abstract: Scientific metadata containing semantic descriptions of scientific data is expensive to capture and is typically not used across entire data analytic processes We present an approach where semantic metadata is generated as scientific data is being prepared, and then subsequently used to configure models and to customize them to the data The metadata captured includes sensor descriptions, data characteristics, data types, and process documentation This metadata is then used in a workflow system to select analytic models dynamically and to set up model parameters automatically In addition, all aspects of data processing are documented, and the system is able to generate extensive provenance records for new data products based on the metadata As a result, the system can dynamically select analytic models based on the metadata properties of the data it is processing, generating more accurate results We show results in analyzing stream metabolism for watershed ecosystem management

TL;DR: In this paper, a method for identifying a first set of metadata associated with a database and retrieving the first set from one or more first memory locations was proposed, which is based on the first sets of metadata.
Abstract: A method includes identifying a first set of metadata associated with a database and retrieving the first set of metadata from one or more first memory locations. The method also includes identifying, based on the first set of metadata, a second set of metadata associated with the database and retrieving the second set of metadata from one or more second memory locations. The method further includes combining the first set of metadata and the second set of metadata into a set of combined metadata.
