Starting withthe development and characteristics of web interface design and information design, as well as the basic theory of visual communication, this paper focuses on the application of graphical forms in web interface design. then, it studies all kinds of information elements in web interface design, withtheir graphical presentation and layouts, to put forward the design approach of information graphical annotation system. At the same time, the gray value of display is introduced into the research of web interface design. Considering the characteristics of visual interaction by users and the development trend of Internet, the methods of standardization of web interface design and quantification of complex visual elements are proposed. Finally, the design methods and principles with practical application value are summarized through the analysis of information graphics based on design works of empirical cases.

web databases contain a huge amount of structured data which are easily obtained via their query interfaces only. the query results are presented in dynamically generated web pages, usually in the form of data records, for human use. the automatical web data extraction is critical in web integration. A number of approaches have been proposed. the early work are most based on the source code or the tag tree of the page. Recent approaches use the visual feature to extract data information, which are better than the previous work. However, these approaches still have inherent limitation. In this paper, we propose a novel approach that make use of visual features to extract data information from web page, including the data records and the data items. the results of this experiment tests on a large set of query result pages in different domain show that the proposed approach is highly effective.

Python is widely used to create and manage complex, database-driven websites. However, due to dynamic features such as dynamic typing of variables, Python programs pose a serious security risk to webapplications. Most security vulnerabilities result from the fact that unsafe data input reaches security-sensitive operations. To address this problem, information flow analysis for Python programs is proposed to enforce this property. information flow can capture the fact that a particular value affects another value in the program. In this paper, we present a novel approach for analyzing information flow in Python bytecode which is a low-level language and is more widely broadcast. Our approach performs a hybrid of static and dynamic control/data flow analysis. Static analysis is used to study implicit flow, while dynamic analysis efficiently tracks execution information and determines definition-use pair. To the best of our knowledge, it is the first one for Python bytecode.

A web attack is an attack against a web server through the HTTP Protocol. By analyzing known web attacks, we find out that each one has its own behavior. Vestiges of their behavior could be detected in non-body parts of the HTTP Protocol. Such information can be used to verify web alerts generated by webapplication Firewalls (WAFs) and web Intrusion Detection systems (web IDSs). In this paper, we propose a method to verify web alerts generated by mentioned sensors. the goal of the alert verification component is to eliminate or tag alerts that do not represent successful attacks. Our approach is based on analyzing HTTP Transaction metadata, including Request method, Request Headers, Status Code, and Response Headers. We implemented an alert verification module, reconfigured ModSecurity, modified a subset of the OWASP ModSecurity Core Rule Set, and developed knowledge-base of web attack vectors to evaluate our method. We show that our approach significantly reduces false and non-relevant alerts with quite low processing overhead, thus enhances the quality of the results.

Many web pages contain geographical information. Some researches bad been reported which try to collect geographical data from web documents and build spatial index. However, it is not easy to search and extract geographic data in web pages. this paper introduces Case Based Indexing systemthat builds Case Base by page layout cues and pattern-based address clustering from web pages. Our method performs massive extraction of geographic features from crawled web pages.

To manage the large volume information in the Brazilian city of Luziania, related to education, entertainment, health and safety, is required the development of an informationsystem capable of performing the computational treatment of such information. A Geographic informationsystem (GIS) is an informationsystem withthe ability to represent alphanumeric and spatial data. In this context, this article proposes the development of a web Geographic informationsystem (GIS web) in order to facilitate the organization, management and visualization of data from city Luziania related to education, entertainment, health and security.

this work implements 3D building models of a university campus with planimetric information for interaction and visualization on a platform that contains a 3D Geographic informationsystem on the web (3D webGIS). ArcGIS Pro was used to obtain geographic information, and the Cesium JS library was used as a webapplication and its 3D modeling engine for conversion to the JavaScript programming language. the development of the platform is a mixed methodology, since it has a quantitative approach to obtain all the infrastructure data of the campus and contain it on the web and a qualitative approach considering that the user must contextualize the experience within the web. A total of 49 3D models of the buildings of the Barcelona campus have been compiled in Cesium Ion and implemented in a 2D map of the campus by means of the JavaScript programming language in the webStorm environment. the presented platform would contribute to intelligent planning for minimize costs, maximize resource utilization in view of intelligent and sustainable buildings in the design and maintenance of constructions, and generate navigation routes so that the university community can be located on the campus.

Message-oriented middleware especially for message queue has been widely used in webapplications and services. Performance and scalability are quite essential in these systems however they often become the bottleneck. Existing message queues are not able to scale out elastically very well. this paper presents a decentralized distributed architecture based on peer to peer model, in which we always deliver messages with zero or one hop and take advantage of zero-copy. We implemented a scaling algorithm that can be adapted to the dynamic scale of requests and make the system scale out elastically. A series of workload tests have proved that our system can have low response latency and achieve linear increasing throughput. Withthese desired properties, the message system can be used to develop large scale webapplications and services and provide high-performance services to users.
