An Emergency Response (ER) Cyber-Physical System (CPS) to avoid landslides and survey areas located on or near slopes is introduced that handles two problems: electronic waste disposal, and environmental disasters. Uncomplicated detection circuits using salvaged components can pinpoint floods in impoverished regions. CPSs simplify hazard prediction and mitigation in disaster supervision. Nonetheless, few green practices and efforts have been accomplished in this regard. Recent technical advances help landslides studies and the evaluation of suitable risk alleviation measures. This work addresses in situ meters, and cameras to observe ground movements more accurately. The ER-CPS identifies and can help mitigate landslides using techniques based on motion detection that can productively predict and monitor the zone conditions to classify it, and the landslide-related data can be transmitted to inspecting stations to lessen the erosion/sedimentation likelihood while increasing security.

The Syntactic web search scheme is upgraded by adding semantics through the recent trends of Semantic web. The importance of Semantic web is due to the increased level of appropriate results on information retrieval. It brings a wide participation of researchers all over the world. Even beginners could gain an easier understanding of the Semantic web standards. This paper clearly illustrates some of the tools and technologies that are applied for effective semantic web development. Most of the efficient tools are open for access. Certain commercial tools for specific mode of development are also available.
