报告内容:

Analyzing text is a fundamental task with many applications such as information retrieval, analysis of recommendations, question answering, and various task related with AI. The bag-of-words and k-gram based methods have, as initial basic approaches, given reasonable success in several areas. However, if we try to understand language content by just seeing a bag of words or a set of k-grams, we may realize something about their limitations, even when they are fed to highly advanced modelling methods. Grammar is what creates conceptual content out of words. Therefore, we suggest a grammatical analysis of text as a basis for the analysis. This does not by itself remove the need for neural networks and other machine learning methods, but, rather, provides an optional way to preprocess and represent the data.
