We propose new instantiations of chosen-ciphertext secure identitybased encryption schemes with wildcards (WIBE). Our schemes outperform all existing alternatives in terms of efficiency as well as security. We achieve these results by extending the hybrid encryption (KEM–DEM) framework to the case of WIBE schemes. We propose and prove secure one generic construction in the random oracle model, ...

Google Translate provides a multilingual machinetranslation service by automatically translating one written language to another. Google translate is allegedly limited in its accuracy in translation, however. This study investigated the accuracy of Google Chinese-to-English translation from the perspectives of formality and cohesion with two comparisons: Google translation with human expert tra...

SNOMED (Systematized Nomenclature of Medicine) is a comprehensive clinical terminology that contains almost 400,000 concepts, since SNOMED is a formal language; it is hard to understand for users who are not acquainted with the formal specifications. Natural language generation (NLG) is a technique utilizing computers to create natural language descriptions from formal languages. In order to ge...

Understanding natural language texts is a simple task for human beings, but despite recent advances, it is still a challenge for computational devices. An important step in allowing machines to understand texts in natural language is to annotate lexemes with semantic information. Semantic information has several levels and aspects, but a type of semantic annotation that has the ability to help ...

Keyword extraction has received an increasing attention as important research topic which can lead to have advancements in diverse applications such document context categorization, text indexing and classification. In this paper we propose STF-IDF, a novel semantic method based on TF-IDF, for scoring word importance of informal documents corpus. A set nearly four million from health-care socia...
