Service Package Recommendation for Mashup Creation via Mashup Textual Description Mining
2016 IEEE International Conference on Web Services (ICWS), 2016Co-Authors: Qi Gu, Jian Cao, Qianyang PengAbstract:Mashup is a developer-centric technique which allows developers to compose existing Web services together to create innovative or consolidated web applications. However, the rapid growth in the number of services and the myriad of functionally similar services make it difficult for developers to select appropriate ones to develop new applications. Therefore, it is vital to recommend a set of suitable services for mashup creation based on functionalities of services and their relationships. To this end, we propose a service package recommendation approach for mashup development, which is based on mashup Textual Description mining to discover semantic relationships among services. Specifically, discourse analysis of computational linguistics is utilized to uncover the structures underneath mashups' functional specifications, then the semantic relationships between services can be learned from their appearances and the constructed structures in mashup specifications. Accordingly, we are able to recommend a package of services that can be used together with high compatibility for a new mashup to be developed. We evaluate our approach on a real-world dataset. Experimental results show that our approach achieves higher accuracy and outperforms other comparative ones.

structural and semantic matching for assessing web service similarity
International Journal of Cooperative Information Systems, 2005Co-Authors: Eleni Stroulia, Yiqiao WangAbstract:The web-services stack of standards is designed to support the reuse and interoperation of software components on the web. A critical step in the process of developing applications based on web services is service discovery, i.e. the identification of existing web services that can potentially be used in the context of a new web application. Discovery through catalog-style browsing (such as supported currently by web-service registries) is clearly insufficient. To support programmatic service discovery, we have developed a suite of methods that assess the similarity between two WSDL (Web Service Description Language) specifications based on the structure of their data types and operations and the semantics of their natural language Descriptions and identifiers. Given only a Textual Description of the desired service, a semantic information-retrieval method can be used to identify and order the most relevant WSDL specifications based on the similarity of the element Descriptions of the available specifications with the query. If a (potentially partial) specification of the desired service behavior is also available, this set of likely candidates can be further refined by a semantic structure-matching step, assessing the structural similarity of the desired vs the retrieved services and the semantic similarity of their identifiers. In this paper, we describe and experimentally evaluate our suite of service-similarity assessment methods.

semantic structure matching for assessing web service similarity
International Conference on Service Oriented Computing, 2003Co-Authors: Yiqiao Wang, Eleni StrouliaAbstract:The web-services stack of standards is designed to support the reuse and interoperation of software components on the web. A critical step in the process of developing applications based on web services is service discovery, i.e., the identification of existing web services that can potentially be used in the context of a new web application. UDDI, the standard API for publishing web-services specifications, provides a simple browsing-by-business-category mechanism for developers to review and select published services. To support programmatic service discovery, we have developed a suite of methods that utilizes both the semantics of the identifiers of WSDL Descriptions and the structure of their operations, messages and data types to assess the similarity of two WSDL files. Given only a Textual Description of the desired service, a semantic information-retrieval method can be used to identify and order the most similar service-Description files. This step assesses the similarity of the provided Description of the desired service with the available services. If a (potentially partial) specification of the desired service behavior is also available, this set of likely candidates can be further refined by a semantic structure-matching step assessing the structural similarity of the desired vs. the retrieved services and the semantic similarity of their identifier. In this paper, we describe and experimentally evaluate our suite of service-similarity assessment methods.

flexible interface matching for web service discovery
Web Information Systems Engineering, 2003Co-Authors: Yiqiao Wang, Eleni StrouliaAbstract:The Web-services stack of standards is designed to support the reuse and interoperation of software components on the Web. A critical step, to that end, is service discovery, i.e., the identification of existing Web services that can potentially be used in the context of a new Web application. UDDI, the standard API for publishing Web-services specifications, provides a simple browsing-by-business-category mechanism for developers to review and select published services. In our work, we have developed a flexible service discovery method, for identifying potentially useful services and assessing their relevance to the task at hand. Given a Textual Description of the desired service, a traditional information-retrieval method is used to identify the most similar service Description files, and to order them according to their similarity. Next, given this set of likely candidates and a (potentially partial) specification of the desired service behavior, a structure-matching step further refines and assesses the quality of the candidate service set. In this paper, we describe and experimentally evaluate our Web-service discovery process.

patterns of injury in hospitalised one year old children analysis by trimester of age using coded data and Textual Description
International Journal of Environmental Research and Public Health, 2016Co-Authors: Debbie Scott, Victor SiskindAbstract:The second year of life is a time of rapid developmental changes. This paper aims to describe the pattern of unintentional injuries to one-year old children in three-month age bands to better understand the risks associated with developmental stages and, therefore, identify opportunities for proactive prevention. Injury surveillance data were used to identify children admitted to hospital in Queensland, Australia for an unintentional injury from 2002–2012. Falls were the most common injury, followed by burns and scalds, contact injuries and poisonings. Falls and contact injuries remained roughly constant by age, burns and scalds decreased and poisonings (by medications) increased. Animal- and transport-related injuries also became more common, immersions and other threats to breathing less common. Within the falls and contact categories falls from play equipment and injuries due to contact with persons increased, while falls down stairs and catching fingers in doors decreased. The pattern of injuries varies over the second year of life and is clearly linked to the child’s increasing mobility and boldness. Preventive measures for young children need to be designed—and evaluated—with their developmental stage in mind, using a variety of strategies, including opportunistic, developmentally specific education of parents; and practitioners should also consider potential for lapses in supervision and possible intentional injury in all injury assessments.

injuries leading to hospitalisation in the first year of life analysis by trimester of age using coded data and Textual Description
Australian and New Zealand Journal of Public Health, 2013Co-Authors: Victor Siskind, Debbie ScottAbstract:Objective: To describe unintentional injuries to children aged less than one year, using coded and Textual information, in three-month age bands to reflect their development over the year. Methods: Data from the Queensland Injury Surveillance Unit was used. The Unit collects demographic, clinical and circumstantial details about injured persons presenting to selected emergency departments across the State. Only injuries coded as unintentional in children admitted to hospital were included for this analysis. Results: After editing, 1,082 children remained for analysis, 24 with transport-related injuries. Falls were the most common injury, but becoming proportionately less over the year, whereas burns and scalds and foreign body injuries increased. The proportion of injuries due to contact with persons or objects varied little, but poisonings were relatively more common in the first and fourth three-month periods. Descriptions indicated that family members were somehow causally involved in 16% of injuries. Our findings are in qualitative agreement with comparable previous studies. Conclusion: The pattern of injuries varies over the first year of life and is clearly linked to the child's increasing mobility. Implications: Injury patterns in the first year of life should be reported over shorter intervals. Preventive measures for young children need to be designed with their rapidly changing developmental stage in mind, using a variety of strategies, one of which could be opportunistic developmentally specific education of parents.

injuries leading to hospitalisation in the first year of life analysis by trimester of age using coded data and Textual Description

Preventive measures for young children need to be designed with their rapidly changing developmental stage in mind, using a variety of strategies, one of which could be opportunistic developmentally specific education of parents. Injuries in young children are of abiding concern given their immediate health and emotional effects, and potential for long-term adverse sequelae. In Australia, in the financial year 2006/07, 2,869 children less than 12 months of age were admitted to hospital for an unintentional injury, a rate of 10.6 per 1,000, representing a considerable economic and social burden. Given that many of these injuries are preventable, this is particularly concerning. Most epidemiologic studies analyse data in five-year age bands, so children less than five years of age are examined as a group. This study includes only those children younger than one year of age to identify injury detail lost in analyses of the larger group, as we hypothesised that the injury pattern varied with the developmental stage of the child. The authors of several North American studies have commented that in dealing with injuries in pre-school children, broad age groupings are inadequate to do justice to the rapid developmental changes in infancy and early childhood, and have in consequence analysed injuries in shorter intervals. To our knowledge, no similar analysis of Australian infant injuries has been published to date. This paper describes injury in children less than 12 months of age using data from the Queensland Injury Surveillance Unit (QISU).
