JoBimText is an open source framework for application of Distributional Semantics using lexicalized features. It is providing a software solution for automatic text expansion using contextualized distributional similarity. For the computation of similarities context features are used.
The project is maintained by the Language Technology group at the TU Darmstadt and IBM Research.

For a quick demonstration you can try out our web demo. The JoBimText pipeline is available for download.


JoBimText overviewJoBimText is a text processing software package. The application works on a phrase or sentence level and scales to web-scale corpora.

The first step is the holing operation that transforms text into a term–feature representation (Jo–Bim). This text representation can be used for contextualization (text expansion, sense disambiguation) or for the calculation of a Distributional Thesaurus (DT).

The DT can be used as a lexical resource and put into a database. Several database servers are supported natively (MySQL, DB2, DCA). Others can be added using an interface. For a distributed database server with strong performance, consider the DCA Server.

Furthermore, it is possible to enrich the DT with sense clusters. The disambiguation of DT entries can be performed with Chinese Whispers clustering, an unsupervised clustering algorithm that detects the number of clusters. The enriched DT can also be accessed from a database using the DT API.
