Dear Director of Publications,

Following the ACM Policy and Procedures on Plagiarism, I write to notify you of an incident of 
plagiarism involving a paper originally published by two of my students and myself in the WWW 
2004 proceedings (ACM Press).

Original paper: R. Akavipat, L.-S. Wu, F. Menczer: Small World Networks in Distributed Web 
Search. Proc. 13th Intl. WWW Conf. Alt. Track Papers and Posters, pp. 396-397, 2004. ACM 
Press.

Plagiarizing paper: Luca Gatani, Giuseppe Lo Re, and Salvatore Gaglio: An Adaptive Routing 
Mechanism for Efficient Resource Discovery in Unstructured P2P Networks. In Proceedings of 
International Conference on Computational Science and Its Applications - ICCSA 2005, Part
III, p. 39, Lecture Notes in Computer Science 3482. Springer.

The Gatani et al. paper, published in the Proceedings of ICCSA, has the very same idea,
algorithm (with some parameter explorations), and identical evaluation as ours, and even 
verbatim reproduction of sentences in our paper, such as the following:

---- duplicate sentences ----
 Our simulator takes a snapshot of the network for every time step. In
 a time step of the simulator, all of the peers process all of their
 buffered incoming messages and send all of their buffered outgoing
 messages. This may include the generation of a local query as well as
 forwarding and responding to the queries received by other peers.
------------------------------

We kindly ask that you investigate this incident and take appropriate measures.

I am forwarding below a copy of my past correspondence with Prof. Marina Gavrilova and the 
other ICCSA 2005 Volume Editors and Conference Co-Chairs. According to Prof. Gavrilova, they 
have contacted the Springer LNCS office back in March 2006 but I have not heard anything since 
then. I have not attempted to directly contact the authors of the plagiarizing paper.

Please let me know if there is any additional information I can provide. Thank you very much for 
your consideration of this matter.

All the best,
-Fil
