This paper presents a kind of method that the mobile terminal is seen as a tool to manage dynamic logistics information and inquiry line. First of all, based on real-time location technology of GPS equipment and the use of the serial port or Bluetooth mobile interface, the system has implemented the reading of the GPS positioning data, then it gives two-way data transmission between servers and the mobile terminal based on Web Service and GPRS/3G. Eventually it has successfully realized to exchange the information between location data and logistic platform and to locate the logistics vehicles. The realization of the system has a strong practical significance to the comprehensive logistics information platform which integrates the information of vehicles, cargo and freight trains.
Information is the soul of the logistics, and the powerful logistics network is a prerequisite for the Fourth Party Logistics. Information network can control all aspects of the logistics supply chain, integrate the national logistics resources effectively, enhance the efficiency and reduce logistics cost. This paper proposes a logistics platform based on WebGIS/3G/GPS, which can share the attribute data and map data in high degree and realize distribute storage. It not only can change the dull attribute data into vivid graphics, but also makes the management and maintenance for massive data convenient and efficient, and control the logistics process accurately and timely. The implementation of the platform will maximize the advantages of the Fourth Logistics, strengthen control over the logistics process.
With the development of the Internet, the online shopping was increasingly into people's life. In order to provide convenient search and price comparison service for shopping online, this article designs and implements automatic search and comparison system based on Deep web. To overcome the difficulties of data capture from the current dynamic webpage, the background’s data capture of this system implements by watir. The search module for end-users implements by JavaEE. The practical application shows that this system can fully satisfy people’s needs in search and comparison.
With the wide application of the Web databases (WDB), it has become a hot topic of the current research to make full use of data. WDB query interface is an important way to get the WDB data, it is a significant prerequisite to obtain the data efficiently that we can realize the full representation and extraction for WDB query interface. This paper presents a new representation based on owl for WDB query interface; at the same time this paper gives the extraction methods based on regular expression and watir for the context of each query interface, form information and the relationship information between the form fields. This work provides an important foundation for the further classification and integration of query interface.
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.
