Information available on the internet is huge, diverse and dynamic. Current Search Engine is doing the task of intelligent help to the users of the internet. For a query, it provides a listing of best matching or relevant web pages. However, information for the query is often spread across multiple pages which are returned by the search engine. This degrades the quality of search results. So, the search engines are drowning in information, but starving for knowledge. Here, we present a query focused extractive summarization of search engine results. We propose a two level summarization process: identification of relevant theme clusters, and selection of top ranking sentences to form summarized result for user query. A new approach to semantic similarity computation using semantic roles and semantic meaning is proposed. Document clustering is effectively achieved by application of MDL principle and sentence clustering and ranking is done by using SNMF. Experiments conducted demonstrate the effectiveness of system in semantic text understanding, document clustering and summarization.
Crop diseases are a considerable danger to the crop's health, affecting the yield. Timely detection is challenging due to a lack of infrastructure in many regions of the world. Since they result in the death of plants, the loss of their product, and the global food problem, plant diseases must be investigated. Crop disease detection has been made possible by recent advancements in computer vision, deep learning, and the growing worldwide adoption of smartphones. Convolutional Neural Networks have significantly improved classifying images in the past several years. The performance of deep learning-based techniques for plant disease recognition under actual circumstances is thoroughly examined in this research. The objective was to offer some principles for conducting a more thorough and realistic examination of deep learning-based approaches for disease recognition. Sequential Architecture was used to classify 38 diseases of 14 crops on a crop leaves image dataset containing 70,295 training and 17,572 testing images. A simple convolutional neural network has been proposed that detects crop diseases seamlessly. The maximum accuracy obtained was 95% on the 14 th epoch. This was accomplished by following the Sequential Model. It is a cuttingedge network that can help new researchers who desire to conduct their studies in deep learning applications with an emphasis on agriculture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
