Thanks to Hamish Cunningham, Antonio S. Valderrábanos, Gabriel Pereira
Lopes, Fabio Ciravegna, Milena Slavcheva and Valerie Mapelli for replying to
our query, which is repeated at the end of this message.
In spite of receiving several replies to our query, we did not succeed in
getting a collection of texts containing named entities that could be used
for the evaluation of named entity recognition software. Most replies
pointed to general purpose collections of parallel text, but we needed a
specific test set of preferably short texts containing many named entities.
Finally, we compiled a test collection of 19 short parallel documents
ourselves. This was done by identifying a number of identical strings in
English texts and their Spanish translations, by hand-picking those strings
that were likely to be named entities, and by then choosing those short
texts that contained many of these hand-picked strings. This small test
corpus is available on request.
Below, you will find the main answers:

A good one but doesn't contain German
Besides, the UN site (www.un.org) contains large amounts of parallel texts
(although not in German).

Johannes Matiasek at OFAI, Vienna, (john@ai.univie.ac.at) developed a named
entity recogniser for German as part of the Facile project. He annotated a
corpus with named entities. Maybe you can contact him and ask for the
corpus. He is a nice guy.

Below you can find information about a parallel German-French corpus. The
style of the texts is, broadly speaking, administrative and you can find
plenty of named entities. From the message below (that I forward to you), I
can see that the corpus is already distributed by ELRA. You can also turn
for information to prof. Wolfgang Teubert at teubertw@hhs.bham.ac.uk who was
the leader of the project producing GeFRePaC at the Institut fuer deutsche
Sprache (IDS) in Mannheim.

Subject: Need for texts to evaluate named entity recognition software in En,
Fr, De and Es
Hello,
we are looking for texts containing many named entities such as peoples'
names, company names, names of organisations/authorities and geographical
places in the languages English, French, German and Spanish.
The texts will be used for the evaluation of named entity recognition
software. Parallel texts (texts and their translations) would be preferred
as they would make the evaluation easier. It is not strictly necessary that
the named entities be marked up in the text.
The evaluation will be carried out by a student, who is writing her Master's
thesis on this subject, in collaboration with the EC's Joint Research
Centre. The thesis will be made publicly available.
Any hints are welcome. Thanks in advance.
