Enriching feature engineering for short text samples by language time series analysis
2020
EPJ Data Science
Preserved Fulltext
In this case study, we are extending feature engineering approaches for short text samples by integrating techniques which have been introduced in the context of time series classification and signal processing ...
The resulting language time series can be characterised by collections of established time series feature extraction algorithms from time series analysis and signal processing. ...

The ETM enriches text representation by incorporating probability distributions generated by an unsupervised algorithm into it. ...
This study proposes the ETM (enrichment by topic modeling) algorithm, based on latent Dirichlet allocation, to smoothen the semantic representations of short sentences. ...
There are two reasons for this: (1) Feature engineering in the Crest and ETM approaches has been proposed especially for the short text classification problem. (2) The trained word vectors are not rich ...

The difference between classifying short text and long documents is that short text is of shortness and sparsity. ...
With the explosive development of mobile Internet, short text has been applied extensively. ...
However, short text has a
series of features, such as shortness, sparsity, lack of semantic and contextual information [1-2]. It
brings challenges for traditional methods to achieve good performance. ...
