Android has been the most popular smartphone system, with multiple platform versions (e.g., KITKAT and Lollipop) active in the market. To manage the application’s compatibility with one or more platform versions, Android allows apps to declare the supported platform SDK versions in their manifest files. In this paper, we make a first effort to study this modern software mechanism. Our objective...

Because of the rapid technological developments in web based geographical information systems, web based map applications and visual tours with 3d models, web applications are getting more indispensable part of presenting geographical information systems through web. In web based geographical information systems, the visualization is more important than desktop information systems. For the need...

Many countries today have “country-centric mobile apps” which are mobile apps that are primarily used by residents of a specific country. Many of these country-centric apps also include a locationbased service which takes advantage of the smartphone’s API access to the smartphone’s current GPS location. In this paper, we investigate how such country-centric apps with location-based services can...

Much of the content of popular Internet information sources is highly dynamic: urgent in nature and sometimes relevant only for a short time. The typical approach to querying such dynamic sources is polling for updates often. This strains the traditional pull-based Internet and wastes network resources on transmitting redundant information. This paper focuses on how to structure the Internet to...

In this paper, we have shown how we developed a web app for an improved Google map view by inputing queries and processing it. It’s a typical location based service. As the name suggests the system is intelligent because the KNN query applied to the google map, or any random KNN messages is processed in an intelligent manner, intelligent in the sense that it reduces traffic and maintains high a...

In this thesis we study two interesting aspects of the problem of Entity Resolution (ER). The goal of ER is to identify and merge records that refer to the same underlying entity. The recent rise in adoption of social networks (Facebook, Google+, Twitter, and others) introduces new issues and twists to the traditional ER problem: crowdsourcing and limited information. We first study a hybrid hu...

Using Google Earth, Google Maps, and/or network visualization programs such as Pajek, one can overlay the network of relations among addresses in scientific publications onto the geographic map. We discuss the pros and cons of various options, and provide software (freeware) for bridging existing gaps between the Science Citation Indices and Scopus, on the one hand, and these various visualizat...

In this paper we describe a system for visualizing and analyzing worldwide research topics, rtopmap. We gather data from google scholar academic research profiles, putting together a weighted topics graph, consisting of over 35,000 nodes and 646,000 edges. The nodes correspond to self-reported research topics, and edges correspond to cooccurring topics in google scholar profiles. The rtopmap sy...
