Current version of the Swedish summarizer

Hercules Dalianis described and demonstrated the current version and the how to evaluate the SweSum summarizer see also First ScandSum meeting Åre

Danish resources tagger and lemmatizer

Dorte Haltrup described the various Danish resources, such as the tokenizer, tagger, lemmatizer and the named entity recognizer. The tokenizer is written in Perl. The tagger is the Brill tagger and the lemmatizer is written in C++. Both the tagger and the lemmatizer is language independent and can be trained for any language. The Named Entity recognizer is currently under development.

Bart Jongejan continued by describing the lemmatizer in dept. The Danish lemmatizer uses both statistical methods and the STO dictionary that has about 0.5 mil words . By training the system on a dictionary the lemmatizer have found 44205 lemmatization rules. Before the lemmatizer is executed it is necessary to run the taggger.

Icelandic resources

Kristin Bjarnadottir described the Icelandic resources. There are one tagged corpus the Icelandic frequency dictionary corpus (IFP) containing 500 000 words and one untagged corpus Institute of lexicography text corpora containing 25 mil. words and then there is also an Icelandic synonym lexicon, Icelandic Resources (HTML)

Norwegian company Cognit AS document analysis and summarization

Till Lech described Cognit's resources. The Corporum product contains taggers which can extract microontolologies, i.e. create relations between concepts. As a spin-off of this is the Corporum Summarizer creates summaries (extracts) of the text. The summarizer seems fast and efficient. The languages treated are Swedish, Norwegian (Bokmål), German and English. Corporum is used by a large number of customers Norsk Hydro, Statoil, etc. Corporum looks in the target group of customers which might use Autonomy.

Finlandic resources

Ari Pirkola from University of Tampere sent me a list of Finnish resources

From SweSum to Scandsum

Martin Hassel described different possible improvements on SweSum and also how to adapt it to other languages see also First ScandSum meeting Åre

Nordoknet and SiteSeeker

Jürgen described the architecture of the Nordic documentation center and how to make information accessible from all webbsites by using SiteSeeker search engine with built-in human language technology. Hercules demonstrated the SiteSeeker applied on all of Nordoknet webbsites.

One thing which Jürgen has to convey to his documentation center partners is that when using Java scripts in webbsite one also need to use clear text links to all web pages otherwise no search engine ever, including SiteSeeker, will manage to index some of the pages. (see here for instructions).
