Hercules described the current Swedish text summarizer, see also
previous minutes First ScandSum meeting Åre

Janne Bondi Johannessen described the Oslo-Bergen tagger which can be used for tagging Norwegian texts. The Oslo-Bergen tagger can be adapted to generate SGML based tags. These tags can be received by the coming new version of the SweSum summarization engine and hence summarize Norwegian texts.

The tagger can be tested here.http://decentius.hit.uib.no:8005/cl/cgp/test.html

We plan to use a server based tagger that can be communicated through SSH protocoll so the new Summarization system will be fully distributed and hence easy to support and update.
The same will be with the Granska Tagger.

The tagger format will be similar to the following:

  <word lemma="ha" tag="verb">Har</word>

Though if the text structure is not alsways hierarchical we must be able to treat it,
adding for example these tags

<div type="s"> between sentences

<word> eksemplet <lemma type="eksempel" cat="subst"> </word>

Victoria Rosén described the lexicon from the Scarrie project. This lexicon contains relations between possible lexical variants in Bokmål, for example between høyesterett and høgsterett. This offers great potential for grouping variants of keywords. The SCARRIE lexicon can be used as a basis for constructing a word list for the current SweSum architecture, or it can be used to define keyword links on the output of the tagger as well as on user keywords.

A paper on SCARRIE is available at

Helge Dyvik talked about Word senses based on parallel corpora.
Helge decribed a method where going back and forth between the processed parallel corpora starting with one lexical item and finding the most closed related in the other corpora / language and then back again to the other corpora / language and hence finding the lexical items which are closest semantically related. This method with enough large parallel corpora can make the building of wordnets / ontologies partly automatized.
