SISELS is a mediation system that enables the configuration of virtual laboratories to provide transparent access to distributed biological resources (data or services). SISELS exploits the metadata associated to the subscribed resources to classify and organize them respect to their structure and content. This way, it is possible to generate subspaces of resources, denominated views respect to the requirements of a group of experts to study a biological problem. A view represents the semantic requirements of a group of experts and a subset of relevant resources satisfying partially or totally these requirements. SISELS uses three main levels of metadata to model the knowledge domain of the virtual laboratory based on the resources’ metadata and the semantic correspondences between the resources and the domain.","PeriodicalId":273670,"journal":{"name":"2009 Mexican International Conference on Computer Science","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117229897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These approaches are presented in the framework of classical query evaluation procedures that rely upon cost models heavily dependent on metadata (e.g. statistics and cardinality estimates) and that typically are restricted to execution time estimation. There are computational environments where metadata acquisition and support is very expensive. Additionally, execution time is not the only optimization objective of interest. A ubiquitous computing environment is an appropriate example where classical query optimization techniques are not useful any more. In order to solve this problem, this article presents a query optimization technique based on learning, particularly on case-based reasoning. Given a query, the knowledge acquired from previous experiences is exploited in order to propose reasonable solutions. It is possible to learn from each new experience in order to suggest better solutions to solve future queries.","PeriodicalId":273670,"journal":{"name":"2009 Mexican International Conference on Computer Science","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126653506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces a service-oriented architecture for solving integration problems with legacy systems of stock quote management on a sugar mill.

To resolve the semantic problems related to TF approaches, the proposed technique disambiguates the words contained in a document and creates a list of super ordinates based on an external knowledge source. In order to reduce the dimension of the document vector, the final set of index values is created by extracting a set of common concepts, shared by multiple related words, from the list of hypernyms. Subsequently, a weight is assigned to each concept index by considering its position in the knowledge source's hierarchical tree (i.e. distance from the substituted words) and its number of occurrences. By applying the proposed technique, we were able to disambiguate words within different contexts, extrapolate concepts from documents, assigning appropriate normalised weights, and significantly reduce the vector dimension.","PeriodicalId":273670,"journal":{"name":"2009 Mexican International Conference on Computer Science","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126586528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The verification techniques applied are desktop inspection, equivalence partitioning and boundary-value analysis, decision table, linearly independent path, and multiple condition coverage. The first one is a static technique, while the others are dynamic. JUnit test cases are generated when dynamic techniques are applied. Both the defects and the execution time are registered. Execution time is considered as a cost measure for the techniques. Preliminary results yield three relevant conclusions. As a first conclusion, performance defects are not easily found. Secondly, unit verification is rather costly and the percentage of defects it detects is low. Finally desktop inspection detects a greater variety of defects than the other techniques.","PeriodicalId":273670,"journal":{"name":"2009 Mexican International Conference on Computer Science","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131552137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many of the existing solutions are based on the willingness of Internet user communities to share their broadband connection at home. However, some other access sharing models have introduce incentives for those users that share their Internet connection. Another aspect that differentiates current solutions is the approach to deploy such a service. In general, these solutions can be grouped in three categories: the ones that follow a guerrilla approach, those that partner with ISPs, and the sharing solutions that originate inside the telcos. These options are compared in this paper from the business and technology angles, discussing the pros and cons of each of them. In addition, a broadband sharing enabling solution, called Extended HotSpots is described. This solution was evaluated during a field trial in the city of Berlin and the results collected are included in this paper.","PeriodicalId":273670,"journal":{"name":"2009 Mexican International Conference on Computer Science","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121649149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
