Transforming the data into a suitable representation is the first key step of data analysis, which the performance of any data-oriented method is heavily dependent on it. This need is concerned with questions surrounding how we can best learn representations for textual entities that are: 1) precise, 2) robust against noisy terms, 3) transferable over time, and 4) interpretable by human inspection.
In this talk, I am going to present significant words language models of a set of documents that capture all, and only, the significant shared terms from these documents. I will also present how to apply significant words language models to several applications like group profiling, relevance feedback, and hierarchical classification and will show how it helps to get a better performance over the state-of-the-art methods.
