TextServer is a platform of language analysis services that can be used to process texts either interactively or in batch mode.

TextServer is powered by the High Performance Computing cluster in the Computer Science Department at UPC, that totals over 1,000 cores and 3TB of RAM.

TextServer offers NLP services based on FreeLing and other tools. Services range from language identification or tokenization to Semantic Role Labelling and Coreference Resolution. Services are offered for a variety of languages, including English, Spanish, Russian, French, German, Italian, Portuguese, Catalan, Galician, Welsch, among others.

TextServer goals

TextServer aims to simplify the use of advanced Natural Language Processing pipelines such as FreeLing, moving them to the cloud and freeing the user from time-consuming installation procedures and complex library API calling.

With TextServer, the user can just submit a document or collection for its processing, and get the results in XML or JSON, among other formats.

The request can be sent manually via a web form, or programmatically from a remote client calling a web-service API.
