Recently the wireless sensor networks have emerged as an attractive solution in a number of applications. The wireless sensor networks have found many applications in different areas, including environmental surveillance, intelligent building, health monitoring, etc. In this paper we present open sensor middleware model based on SOA (Service Oriented Architecture) in wireless sensor networks. T...

XOM is an open source API for processing XML with Java using a streaming tree model. XOM was implemented using the cathedral model of open source development rather than a bazaar. As such, a set of explicit design principles for both XML APIs specifically and Java APIs in general has informed its development. This paper discusses these principles. XOM Design Principles Table of

UNLABELLED PedVizApi is a Java API (application program interface) for the visual analysis of large and complex pedigrees. It provides all the necessary functionality for the interactive exploration of extended genealogies. While available packages are mostly focused on a static representation or cannot be added to an existing application, PedVizApi is a highly flexible open source library for ...

We analyze the version history of software projects to determine API-related profiles of software developers. To this end, we identify API references in source-code changes and aggregate such references through suitable metrics that provide different views on the API usage per developer so that certain conclusions regarding developer experience or comparisons between developers become feasible....

Ontology matching consists of generating a set of correspondences between the entities of two ontologies. This process is seen as a solution to data heterogeneity in ontology-based applications, enabling the interoperability between them. However, existing matching systems are designed by assuming that the entities of both source and target ontologies are written in the same languages ( English...

Learning and remembering how to use APIs is hard. While codecompletion tools list all the API methods available on a given object, reading through a long list of API method names and their associated documentation is tedious, and users can be easily overloaded with too many suggestions. While several researchers proposed techniques for recommending APIs, their accuracy is low. We present a nove...

Two movements are currently influencing the owners of public datasets to open up what’s inside their organization: the Web API movement and the Open Data movement. The first advocates open Web-services which can provide a specific use case of information. The second advocates raw data to be published to the Web to be able to get used, reused and redistributed. What are the advantages and disadv...

This paper presents an overview of the software for wordnet processing Hydra. The system has fully-fledged GUI and API, both working with powerful modal query language. Hydra has been used for the development of the Bulgarian WordNet for the last 7 years and recently was improved, became open source and is distributed as part of the Meta-Share platform.

Existing tool integration approaches integrate various tools directly through tool proprietary APIs. This kind of integration lacks standardization and are different case by case. Integration based upon common tool metamodels also turns to be too complicated and hard to maintain. In this paper we provide an approach which integrates tools based on a combination of tool metamodels and an integra...

Our use case for maintenance of the Drug Ontology includes a semi-automated, daily process capable of importing new, relevant information from a variety of linkable resources, using fast and flexible algorithms with full access to all data. Structured Product Labels contain linkable information regarding FDA approved drug products and the drug packages in which they are sold, as well as ingredi...
