ElixirFM 1.1 Update + Wiki + API

The ElixirFM Functional Arabic Morphology project has released an update of its libraries, executables, data, and documentation at SourceForge.

The current version 1.1.927 includes important improvements in the performance of the system and comes with enhanced user and programming interfaces. Next to the ElixirFM Online Interface, the project also features:

ElixirFM Wiki
documentation for the project has been set up, which now brings notable information for the computational linguists and interested developers who would like to explore the ElixirFM system more deeply and use it in their applications
ElixirFM API
there is a powerful ElixirFM programming interface for Perl which allows you to invoke the elixir executable from your code and further parse and process the results easily

The ElixirFM lexicon has been extended and refined, and a number of words have been encoded in a way that makes their deep word structure more explicit. The sources of the lexicon plus the editing software are available freely upon request.

ElixirFM now operates more smoothly in all its modes. In particular, the resolve mode involves solution pruning and its morphological analyses now comply with most linguistic constraints. Likewise, the online inflect and derive modes have been integrated with lookup, due to which word form generation becomes much more intuitive and yet more enjoyable.

ElixirFM 1.1 Online Interface

In the recent months, the ElixirFM project has undergone considerable improvement in various respects. We have worked most on developing the programming library and on refining the lexicon. On top of these essential components, we have built a user-friendly web application, the ElixirFM 1.1 Online Interface.

ElixirFM is a computational model of the morphology of Modern Written Arabic. It provides the user with four different modes of operation, in addition to the unique lexical resource and the other open-source functions of the implementation.

provides tokenization and morphological analysis of the inserted text, even if you omit some symbols or do not spell everything correctly. You can experiment with entering the text not only in the original script and orthography, but also in other notations, including a purely phonetic transcription.
lets you inflect words into the forms required by context. You only need to define the grammatical parameters of the expected word forms. You can either enter natural language descriptions, or you can specify the parameters using the positional morphological tags.
lets you derive words of similar meaning but different grammatical category. You only need to tell the desired grammatical categories, using either natural language descriptions, or the positional morphological tags.
can lookup lexical entries by the citation form and nests of entries by the root. You can even search the dictionary using English.

The online interface includes example queries for each of the modes. It further incorporates several interactive tools to facilitate the browsing of the results returned by the system.

Information on the programming libraries and the research context of the project is in part available in our papers. Yet, we would like to extend the documentation according to the requirements of the users, and would be happy to discuss any unclear issues with anyone interested.

Enjoy ... and let us know in case of questions or comments :)
