Mining Summary of Short Text with Centroid Similarity Distance
Text summarization aims at producing a concise summary that preserves key information. Many textual inputs are short and do not fit with the standard longer text based techniques. Most of the existing short text summarization approaches rely on metadata information such as the authors or reply networks. However, not all raw textual data can provide such information. In this paper, we present our method to summarize short text using a centroid based method with word embeddings. In particular, we consider the task when there is no metadata information other than the text itself. We show that the centroid embeddings approach can be applied to short text to capture semantically similar sentences for summarization. With further clustering strategy, we were able to identify relevant sub topics that further improves the context diversity in the overall summary. The empirical evaluation demonstrates that our approach can outperform other methods on two annotated LREC track dataset.
