An increasing percentage of US waste methane (CH4) emissions come from wastewater treatment (10% in 1990 to 14% in 2019), although there are limited measurements across the sector, leading to large uncertainties in current inventories. Unlike traditional methods, which are expensive and time-consuming even for small samples, NLP techniques use big data and social media and are very economic, fast, and immediate. You can use the equivalent formula d = rt which means . Hutto, C. & Gilbert, E. Vader: A parsimonious rule-based model for sentiment analysis of social media text. Our analysis also identified three topics: (1) requests for support measures for distance learning, (2) concerns about distance learning and its application, and (3) anxiety about the government decrees introducing the red zones and the corresponding restrictions.

The dynamic topic model shows that the peoples concerns changed over time (Fig. While distance learning has generated and still generates fears and concerns, integrated digital learning has already proven itself more effective than traditional teaching. The basic idea of LDA is that each document has a topic, and a topic can be defined as a word distribution31. Primer component analysis using average distribution forseveral topic numbers k. In our analysis, we find that the tweet content changes over time, and therefore, after initializing through the LDA model, its dynamic version (DLDA) is used.

The text content of a tweet is a short microblog message containing at most 280 characters; this feature makes tweets particularly suitable for natural language processing (NLP) techniques, which are widely used to extract insights from unstructured texts. Based on linear array 3D imaging, this paper introduces a keystone algorithm combined with the arc array SAR 2D imaging method and proposes a modified 3D imaging algorithm based on keystone transformation. These results need to be interpreted in light of recent literature on psychological dimensions of the COVID-19 pandemic.
