Late breaking results submissions will be held to the same standards of scientific quality as full papers. Evaluation criteria will include novelty and significance of the contribution to the field, quality of research, quality of writing, and contribution to conference program diversity. The highest weight will be placed on novelty of the contribution, so authors should clearly state and support novelty claims by comparing and contrasting the work to previous research. Incremental research is discouraged for this call.

Short versions of rejected papers from the main WSDM CFP are allowed, but the WSDM reviews must be included along with a rebuttal.

The topics include all WSDM'09 topics. Topics that are especially encouraged include:

Paper Format: papers should be a maximum of 4 pages long, and must report original research not accepted or under submission to any journal or conference with public proceedings (previous submissions in informal workshops or as posters are allowed, but must be indicated). Short versions of papers already accepted at WSDM are not allowed. Short versions of rejected papers from the main WSDM CFP are allowed, but the WSDM reviews must be included along with a rebuttal. Papers should be 4 pages max. and must be formatted according to ACM guidelines and style files.
