Static semantic analysis of dynamic languages

Abstract: Analyzing dynamic source code. A method includes accessing a specific metadata format data structure. The data structure was created by obtaining one or more first data structures defining constructs in a body of dynamic language source code. From the one or more first data structures, identifier information is extracted for one or more of the defined constructs. Knowledge about the constructs is augmented. The metadata format data structure is parsed to compute metrics about the metadata format data structure. The metrics about the metadata format data structure are provided to a user.

Data using device and method, metadata use management device and method, and program

Abstract: PROBLEM TO BE SOLVED: To provide a data using device capable of providing metadata of further high quality over many more contents. SOLUTION: The content using device 102 acquires metadata including attribute information of a content of using object, which also includes provider information showing the provider of the metadata from a metadata delivery server 101. The content using device 102 acquires advertisement information from an advertisement delivery server 103 in a case that a content using the metadata is used, presents the advertisement information, and transmits the provider information contained in the metadata to an advertisement agent server 104. The advertisment agent server 104 performs processing for paying a reward to the provider shown by the provider information. According to this, formation of metadata is promoted, and metadata of further high quality are expected to be provided over many more contents. COPYRIGHT: (C)2006,JPO&NCIPI

Mapping Methods Metadata for Research Data

Abstract: Understanding the methods and processes implemented by data producers to generate research data is essential for fostering data reuse. Yet, producing the metadata that describes these methods remains a time-intensive activity that data producers do not readily undertake. In particular, researchers in the long tail of science often lack the financial support or tools for metadata generation, thereby limiting future access and reuse of data produced. The present study investigates research journal publications as a potential source for identifying descriptive metadata about methods for research data. Initial results indicate that journal articles provide rich descriptive content that can be sufficiently mapped to existing metadata standards with methods-related elements, resulting in a mapping of the data production process for a study. This research has implications for enhancing the generation of robust metadata to support the curation of research data for new inquiry and innovation.

Automated Metadata in Multimedia Information Systems: Creation, Refinement, Use in Surrogates, and Evaluation

Abstract: Improvements in network bandwidth along with dramatic drops in digital storage and processing costs have resulted in the explosive growth of multimedia (combinations of text, image, audio, and video) resources on the Internet and in digital repositories. A suite of computer technologies delivering speech, image, and natural language understanding can automatically derive descriptive metadata for such resources. Difficulties for end users ensue, however, with the tremendous volume and varying quality of automated metadata for multimedia information systems. This lecture surveys automatic metadata creation methods for dealing with multimedia information resources, using broadcast news, documentaries, and oral histories as examples. Strategies for improving the utility of such metadata are discussed, including computationally intensive approaches, leveraging multimodal redundancy, folding in context, and leaving precision-recall tradeoffs under user control. Interfaces building from automatically generated metadata are presented, illustrating the use of video surrogates in multimedia information systems. Traditional information retrieval evaluation is discussed through the annual National Institute of Standards and Technology TRECVID forum, with experiments on exploratory search extending the discussion beyond fact-finding to broader, longer term search activities of learning, analysis, synthesis, and discovery.

A Knowledge Network Constructed by Integrating Classification, Thesaurus, and Metadata in Digital Library

Abstract: For the digital libraries of China, the development of networked information resources, especially of metadata, is still a principal task. At the same time, many information resources have been accumulated and the exploitation of them is far from sufficient. The current chief utility — keyword search undermines seriously the potential value of information resources, especially the metadata, which contains valuable content description and indexing information. To solve this problem, we have devised a new paradigm — an integrated knowledge network. It is formed by merging the classification and thesaurus into a concept network and then distributing the metadata records into the concept nodes according to their subjects, just like the “shelving” of the metadata. We have built an experimental system, VISION, by incorporating a portion of the Chinese Classification and Thesaurus with the bibliographic data of the computing domain from Peking University Library. Such a knowledge network is not only a framework ...
