我希望通过可视化本体来理解和让别人理解.我更喜欢自上而下的类层次结构.我曾经使用过OntoGraph它Protégé,但我对这个数字并不满意:(.我也使用过Microsoft Visio和模板Ontology,但这也没有让我印象深刻.
通过这个问题,我想知道哪个是用于将本体可视化用于一般目的和/或用于特定目的的最佳工具(如撰写学术论文).
谢谢.

我想在Android 2.1设备上更改3G dns设置.我设法在我的设备上安装busybox,我也可以通过使用获取dns信息adb shell getprop | grep dns.唯一的问题是,它让我net.pdp0.dns1和net.pdp0.dns2,不net.rmnet0.dns1和net.rmnet0.dns1,所以我不能更改设置.
我知道这net.rmnet0.dns1是为了3G连接,那么呢net.pdp0.dns1？我怎样才能改变net.rmnet0.dns1？
谢谢
是否有可能以编程方式找出两个实例是否属于同一类(使用api,如JENA)
我有一个Android应用程序,在项目的/ libs /目录中有dnsjava.jar.一切都很好,可以打包成APK(没有proguard).
但是,当我将proguard引入project.properties(在eclipse中)时,我收到以下警告:

你好,我正在构建的应用程序可以处理存储在服务器上的很多图像,并且需要在列表视图中显示它们.我希望能够将它们存储在一个文件中.
到目前为止,这是我的代码
var imageUrl = new Java.Net.URL(obj.imageUrl);
var bitmap = Android.Graphics.BitmapFactory.DecodeStream(imageUrl.OpenStream());
var image = new Android.Graphics.Drawables.BitmapDrawable(bitmap);
但我不知道如何保存图像或保存图像.
任何帮助？
谢谢
当我使用Xamarin(mono for android)在C#中编译我的代码时,我看到在bin/目录中创建了以下5个文件.
有人可以解释这些文件的含义以及是否可以使用这些文件手动部署我的应用程序(不使用Xamarin)？
