Dact

Dact is a tool for viewing and analyzing Alpino corpora. It is a user-friendly replacement for the excellent Alpino Treebank Tools.

With Dact you can open and query Dact corpora, compact corpora and directories with XML files. Dact can show trees and count occurrences for almost anything you can query using XPath2 and XQuery expressions. Instantaneously.

Features

  • Easy to use interface

    Dact features an easy to use interface that works like any other desktop application.

  • Tree

    Parsed sentences are shown as trees and nodes that match your XPath query are highlighted. You can print a tree or save it as PDF. And you can click a node to inspect it in the inspector.

  • Node inspector

    Inspect tree nodes to see their attributes. These are the attributes you can use to refine you XPath queries. Any attribute encoded in the corpus is shown.

  • Statistics

    Because Dact uses DBXML to store corpora, queries can be run quickly. The results of these queries can be copy–and–pasted into almost any program or spreadsheet.

  • Sentences

    Gain insight in your corpus by looking at matched words in their context, or hide the context completely.

  • Download new corpora

    Download corpora directly from within the app. You can bring your own compact corpus as well, or even a folder with XML files.
