Project structure

The project structure is displayed in the Project Explorer. You can create a Contained or a Partial project; the difference lies in that the Contained project does not need to have an Alien documents section, since all input documents fit one of the defined document classes, whereas in the Partial project this is not so.
Parts of contained and partial projects

Contained project structure:

  • Training set

  • Stopwords

  • Metawords

  • Phrases

  • Test set

  • Test results

Partial project structure:

  • Training set

    • Alien documents

  • Stopwords

  • Metawords

  • Phrases

  • Test set

    • Alien documents

  • Test results

In case you have a large number of documents in your Training set or Test set, you can easily locate one specific document in the Main panel view of the particular class to see all relevant information about it. While a document is selected in Project Explorer for viewing its contents, click the Locate in parent button in the header of Project Explorer and your selected document gets highlighted in green in the Main panel view of the container class.
