HSpam14 Dataset

The HSpam14 dataset described in our SIGIR 2015 paper is available at links offered by Dropbox and/or Microsoft OneDrive. The dataset in compressed format is about 74.7MB and the uncompressed version HSpam14_dataset.txt is about 308MB.

The text file contains three columns: tweet_id, label, and step (see sample data on the right). The label field contains one of three values {0, 1, -1} where: 0 is for ham (or non-spam tweet), 1 is for spam tweet, and -1 is for those tweets that can not be labeled as spam or ham even after manual inspection. The step field contains values from 1 to 6, describing at which step the tweet was labeled during the labeling process:
1 => Manual annotation HSpam14 Sample
2 => kNN-based annotation
3 => User-based annotation
4 => Domain-based annotation
5 => Reliable ham tweet detection
6 => EM-based annotation

Please refer to the following paper for more detailed description of the dataset.

Wikipedia Keyphraseness

This dataset contains a collection of keyphraseness values for phrases extracted from Wikipedia articles. The keyphraseness value Q(s) of a phrase s is the probability that the phrase appears in a Wikipedia article as being anchor text. In total, 4,342,732 phrases are extracted from the English Wikipedia dump created on January 30, 2010. In this release, we remove the 184,979 phrases containing non-English characters. Among the remaining 4,157,753 phrases, about 1.9 million phrases have non-zero keyphraseness values. This dataset contains one text file and a readme file in zip format (about 45MB in size). The dataset can be downloaded through links by Dropbox or Microsoft OneDrive .
This dataset has been used in the following 3 papers. Please refer to the papers for more details about the dataset and how the keyphraseness values can be used in various tasks (All papers can be downloaded freely from ACM digital library using the links below). This dataset is released solely for research purposes. Please cite at least one of the following 3 papers if you use this dataset in your research.

Tag Visual-Representativeness

The data set used for computing the Image Tag Clarity is available online at NUS-Wide. The normalized image tag clarity scores for the 5981 most popular tags are available in Excel format. Note that, the values reported here might be slightly different from the values reported in the WSM'09 paper due to the different number of dummy tags used for estimating the expected image clarity scores. The mean/std of image clarity scores for a given frequency reported here are estimated through 500 dummy tags (see MM'10 paper). Please cite the following papers if you use the above results in your work (e.g., filtering tags by visual concepts, visual representativeness, or others). Tag labels used in MM'10 paper experiments are available in Excel format. Please drop me an email at axsun AT ntu DOT edu DOT sg if you have any comments regarding the paper or the experimental results.
