- If you use this short text dataset, please cite our paper:
[1]. 2015NAACL VSM-NLP workshop-"Short Text Clustering via Convolutional Neural Networks"
and acknowledge Kaggle for making the datasets available. - We do not remove any stop words or symbols in the text;
- If you run the Classification ACC.m, please run it on 64-bit machine;
- Classification is fast, while Clustering is very slow via KMeans on so high-dimensionality text features, about 2 hours once. If you want to run clustering via KMeans, please have a little patience, and we strongly suggest that you directly refer the KMeans results in our paper [1] which reports the average results by running KMeans 500 times;

./rawText: Raw text, 20,000 titles as short texts
-- label_StackOverflow.txt: Each title plus a tag/label at the end;
-- title_StackOverflow.txt: Each title on each line;
-- vocab_emb_Word2vec_48.vec: Word2vec trained from a large corpus of StackOverflow dataset;
-- vocab_emb_Word2vec_48_index.dic: Word2vec index list corresponds with vocab_withIdx.dic;
-- vocab_withIdx.dic: Vocabulary index.
./matlab_format: Matlab format of rawText
-- StackOverflow.mat: fea is vsm model, and gnd is the label index.
./benchmarks: Contains some benchmarks, such as classfication and clustering
-- Classification_ACC.m: Test the classification performance with TF-IDF+SVM, and the ACC is 81.55%
-- predict.mexw64: LibSVM libraries;
-- svmpredict.mexw64
-- svmtrain.mexw64
-- train.mexw64
-- tf_idf.m: Compute TF-IDF;
-- Clustering_ACC_NMI.m: Test the clustering performance with TF-IDF+KMeans, and the ACC is 20.31% and NMI is 15.64% by 500 runs;
-- normalize.m: normalize the feature vectors;
-- bestMap.m: Permutation mapping function maps each cluster label to the equivalent label from the text data;
-- MutualInfo.m: Compute normalized mutual information metric;
