Having studied in China for a couple of years, I can speak Chinese fluently and am very interested in Chinese culture and history. I was reading the June issue of China Today and was impressed with the smiling face of a Chinese lady holding a bunch of yellow and white chrysanthemums. It is in a special report titled “Who Will Triumph in the Horticulture Industry,” which gives a panoramic view of the 2019 Beijing International Horticulture Exhibition. It reminds me of a group of photos shot by my former colleague and his wife who is a famous journalist in Belarus. The couple plan to have an exhibition of their photos featuring all kinds of smiling faces of Chinese people taken during their stay in China for almost two decades.展开更多

It also serves businesses as it keeps tracking user feedback. The sheer volume of online reviews makes it difficult for a human to process and extract all significant information to make purchasing choices. As a result, there has been a trend toward systems that can automatically summarize opinions from a set of reviews. In this paper, we present a hybrid algorithm that combines an auto-summarization algorithm with a sentiment analysis (SA) algorithm, to offer a personalized user experiences and to solve the semantic-pragmatic gap. The algorithm consists of six steps that start with the original text document and generate a summary of that text by choosing the N most relevant sentences in the text. The tagged texts are then processed and then passed to a Naive Bayesian classifier along with their tags as training data. The raw data used in this paper belong to the tagged corpus positive and negative processed movie reviews introduced in [1]. The measures that are used to gauge the performance of the SA and classification algorithm for all test cases consist of accuracy, recall, and precision. We describe in details both the aspect of extraction and sentiment detection modules of our system.展开更多
