چکیده

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 social media was collected trained order draw model find the embeddings. Then, features space were utilized rearrange original TF-IDF scores through iterative solution so improve moderate performance algorithm texts. After testing proposed with 200 randomly chosen documents, our managed decrease mean error rate by factor 50% reaching 13.7%, opposed 27.2% TF-IDF.

Advances in Security in Computing and Communications

To detect unknown malware, heuristic methods or more generally statistical approaches are the most promising research trends nowadays, but their computing and detection performances are generally not compatible with what users do accept. Hence, most commercial AV products still heavily rely on signature-based detection (opcodes, control flow graph, and so on). This implies that frequent and pri...

Guest Editorial: Advances in Secure Distributed and Network-Based Computing

Modern information systems are geographically distributed, parallel and network-based computing systems. The vulnerability of such computing systems greatly exceed the vulnerability of stand-alone computers. This is due, primarily, to the openness scale and heterogeneity of computer networks themselves. Accordingly, there are many ways to realize modern network attacks against distributed, para...
