Challenges for Dataset Search
Ranked search of datasets has emerged as a need as shared scientific archives grow in size and variety. Our own investigations have shown that IRstyle, feature-based relevance scoring can be an effective tool for data discovery in scientific archives. However, maintaining interactive response times as archives scale will be a challenge. We report here on our exploration of performance technique...
متن کاملTraining Radial Basis Function Neural Network using Stochastic Fractal Search Algorithm to Classify Sonar Dataset
Radial Basis Function Neural Networks (RBF NNs) are one of the most applicable NNs in the classification of real targets. Despite the use of recursive methods and gradient descent for training RBF NNs, classification improper accuracy, failing to local minimum and low-convergence speed are defects of this type of network. In order to overcome these defects, heuristic and meta-heuristic algorith...
متن کاملYaanii: Effective Keyword Search over Semantic Dataset
Nowadays data is disseminated in a number of different sources, from databases systems to the Web, from a traditional structured organization (relational) to a semi-structured (XML), up to the unstructured ones (text in Web documents). Although availability of data is constantly increasing, one principal difficulty users have to face is to find and retrieve the information they are looking for....
متن کاملA Search Task Dataset for German Textual Entailment
We present the first freely available large German dataset for Textual Entailment (TE). Our dataset builds on posts from German online forums concerned with computer problems and models the task of identifying relevant posts for user queries (i.e., descriptions of their computer problems) through TE. We use a sequence of crowdsourcing tasks to create realistic problem descriptions through summa...
