TagyuLib - Tagyu .NET Client Library


I have finished writing a .NET client library for Tagyu's REST Web-Service. Tagyu is a hosted service that uses human intelligence to suggest tags and categories relevant to a block of text.

TagyuLib (that’s my creative name for the .NET API) supports everything that the REST API of Tagyu allows you to do as of now. So it supports both classification queries and related-tags queries. It also allows you to pass your username/password to Tagyu through HTTP basic authentication scheme. If you're wondering what am I talking about here, you should really be reading Tagyu REST web service documentation first.

I have created a project at GotDotNet CodeGallery to share the source code of TagyuLib and it would be great to see people participate.

I hope some people would find TagyuLib useful and I would love to hear from them. But right now it is 2:15 AM and I need to get some sleep.

Update on March 25, 2006

Here is the class diagram and some sample code to get you started.

Sample Code


Determining tags and category

You need to instantiate a new TagyuService object and simply call its GetClassification method passing-in your text. GetClassification will return you a ClassificationSuggestion object and you can loop through the items in its Tags property to do whatever you want. You can also get the category for your text from the Category property of the ClassificationSuggestion object that you got back.


  string inputText = Console.ReadLine();

  TagyuService ts = new TagyuService();

  ClassificationSuggestion s = ts.GetClassification(inputText);

  Console.WriteLine("Suggested Tags are: ");

  foreach (Tag tg in s.Tags) {
      Console.WriteLine(tg.Value);
  }

  Console.WriteLine("Suggested Category is: {0}", s.Category);



Determing related tags

That's equally simple. All you need to do is instantiate a new TagyuService object and call its GetRelatedTags method passing in the tag for which you wish to see related tags. GetRelatedTags returns a RelatedSuggestion object and you can loop through the items in its Tags property.


  Console.WriteLine("Enter a Tag");

  string inputTag = Console.ReadLine();

  TagyuService ts = new TagyuService();

  RelatedSuggestion r = ts.GetRelatedTags(inputTag);

  Console.WriteLine("Related tags are: ");

  foreach (Tag tg in r.Tags) {
      Console.WriteLine(tg.Value);
  }



Using your Tagyu username and password

As of now, unregistered users can make one request per minute from a single IP address to Tagyu and requests beyond this limit result in an error. So if this bothers you, you should create an account at Tagyu. You can pass your username and password to Tagyu through TagyuLib simply by setting these properties on the TagyuService object before invoking GetClassification and GetRelatedTags methods. Here's how:


  string inputText = Console.ReadLine();

  TagyuService ts = new TagyuService();

  ts.Username = "[YOUR-USERNAME]";
  ts.Password = "[YOUR-PASSWORD]";

  ClassificationSuggestion s = ts.GetClassification(inputText);

  Console.WriteLine("Suggested Tags are: ");

  foreach (Tag tg in s.Tags) {
      Console.WriteLine(tg.Value);
  }

  Console.WriteLine("Suggested Category is: {0}", s.Category);
