Article No.: 15
DOI: 10.1145/2019618.2019621

Collaborative tagging or social bookmarking is a main component of Web 2.0 systems and has been widely recognized as one of the key technologies underpinning next-generation knowledge management platforms. In this article, we propose a...

Cloud-based malware detection for evolving data streams
Mohammad M. Masud, Tahseen M. Al-Khateeb, Kevin W. Hamlen, Jing Gao, Latifur Khan, Jiawei Han, Bhavani Thuraisingham
Article No.: 16
DOI: 10.1145/2019618.2019622

Data stream classification for intrusion detection poses at least three major challenges. First, these data streams are typically infinite-length, making traditional multipass learning algorithms inapplicable. Second, they exhibit significant...

From telesales to tele-advisory in travel agencies: Business problems, generic design goals and requirements
Susanne Schmidt-Rauch, Gerhard Schwabe
Article No.: 17

This article describes a multiloop design approach, demonstrating two concatenated build-and-evaluate loops of a project that aims at enhancing and improving tele-counseling at travel agency call-centers. The socio-technical system design intends...

A multilabel text classification algorithm for labeling risk factors in SEC form 10-K
Ke-Wei Huang, Zhuolun Li
Article No.: 18
DOI: 10.1145/2019618.2019624

This study develops, implements, and evaluates a multilabel text classification algorithm called the multilabel categorical K-nearest neighbor (ML-CKNN). The proposed algorithm is designed to automatically identify 25 types of risk factors with...
