A Survey of Automatic Query Expansion in Information Retrieval
Claudio Carpineto, Giovanni Romano
Article No.: 1
DOI: 10.1145/2071389.2071390

The relative ineffectiveness of information retrieval systems is largely caused by the inaccuracy with which a query formed by a few keywords models the actual user information need. One well known method to overcome this limitation is automatic...

A Comparative Study of Palmprint Recognition Algorithms
David Zhang, Wangmeng Zuo, Feng Yue
Article No.: 2
DOI: 10.1145/2071389.2071391

Palmprint images contain rich unique features for reliable human identification, which makes it a very competitive topic in biometric research. A great many different low resolution palmprint recognition algorithms have been developed, which can...

Flow Logic for Process Calculi
Hanne Riis Nielson, Flemming Nielson, Henrik Pilegaard
Article No.: 3
DOI: 10.1145/2071389.2071392

Flow Logic is an approach to statically determining the behavior of programs and processes. It borrows methods and techniques from Abstract Interpretation, Data Flow Analysis and Constraint Based Analysis while presenting the analysis in a style...

A Survey on Personalized TV and NGN Services through Context-Awareness
Songbo Song, Hassnaa Moustafa, Hossam Afifi
Article No.: 4
DOI: 10.1145/2071389.2071393

The advances in IPTV (Internet Protocol Television) technology enable a new user-centric and interactive TV model, in which context-awareness is promising in making the user’s interaction with the TV dynamic and transparent. Our research...

Flow Oriented Approaches to QoS Assurance
Robert Wójcik, Andrzej Jajszczyk
Article No.: 5
DOI: 10.1145/2071389.2071394

The following flow-oriented architectures for quality of service assurance in IP networks are surveyed: Integrated Services, Connectionless Approach to QoS guarantees, Dynamic Packet State, Caspian Networks and Anagran, the Feedback and...
