ANNIS: a linguistic database for exploring information structure
In this paper, we discuss the design and implementation of our first version of the database "ANNIS" (ANNotation of Information Structure). For research based on empirical data, ANNIS provides a uniform environment for storing this data together with its linguistic annotations. A central database promotes standardized annotation, which facilitates interpretation and comparison of the data. ANNIS is used through a standard web browser and offers tier-based visualization of data and annotations, as well as search facilities that allow for cross-level and cross-sentential queries. The paper motivates the design of the system, characterizes its user interface, and provides an initial technical evaluation of ANNIS with respect to data size and query processing
Simplified Distributed Programming with Micro Objects
Developing large-scale distributed applications can be a daunting task.
object-based environments have attempted to alleviate problems by providing
distributed objects that look like local objects. We advocate that this
approach has actually only made matters worse, as the developer needs to be
aware of many intricate internal details in order to adequately handle partial
failures. The result is an increase of application complexity. We present an
alternative in which distribution transparency is lessened in favor of clearer
semantics. In particular, we argue that a developer should always be offered
the unambiguous semantics of local objects, and that distribution comes from
copying those objects to where they are needed. We claim that it is often
sufficient to provide only small, immutable objects, along with facilities to
group objects into clusters.Comment: In Proceedings FOCLASA 2010, arXiv:1007.499
Principles of Multimedia News Systems for Business Applications
In the past few years considerable demand for business oriented multimedia information systems has developed. A multimedia information system is one that can create, import, integrate, store, retrieve, edit, and delete two or more types of media materials in digital form, such as audio, image, full-motion video, and text information. Multimedia information systems play a central role in many business activities. They represent a very special class complex computing systems. This paper surveys a special type of multimedia information systems: multimedia news systems. Multimedia news systems deal with architectures to manage complex multimedia news databases, online presentation and distribution services or the integration of several existing services to meta-services using intelligent news retrieval engines. The leading presentation platform in multimedia news presentation is news networks providing television services and Internet content distribution. The primary focus is on advanced multimedia news systems infrastructure, document standards, application architecture and principles for multimedia news on the Web that suggest long-term trends in this increasingly important area.multimedia, information systems, business applications
LAS: a software platform to support oncological data management
The rapid technological evolution in the biomedical and molecular oncology fields is providing research laboratories with huge amounts of complex and heterogeneous data. Automated systems are needed to manage and analyze this knowledge, allowing the discovery of new information related to tumors and the improvement of medical treatments. This paper presents the Laboratory Assistant Suite (LAS), a software platform with a modular architecture designed to assist researchers throughout diverse laboratory activities. The LAS supports the management and the integration of heterogeneous biomedical data, and provides graphical tools to build complex analyses on integrated data. Furthermore, the LAS interfaces are designed to ease data collection and management even in hostile environments (e.g., in sterile conditions), so as to improve data qualit
