13:05:24 <fsasaki> topic: meeting start
13:06:20 <fsasaki> phil: did a review of use cases this morning. not too much change, missed one that christoph added.
13:06:32 <fsasaki> https://www.w3.org/community/rax/wiki/Draft_Material#Data_acquisition_from_job_postings_via_GATE
13:06:53 <fsasaki> phil: thanks a lot for adding this - can you give a brief description?
13:07:05 <fsasaki> s/this/this, christoph/
13:07:48 <fsasaki> christoph: sure. have not yet managed to share the descriptions, I have more material, and will get it done to share this
13:08:17 <fsasaki> ... will also add more concrete examples. Application setting is: we collect job postings in the form of plain text from the web
13:08:31 <fsasaki> ... we do named entity recognition with gate, and we get XML output
13:08:40 <fsasaki> ... begining and end of each token is annotated
13:09:03 <clange> text text text <start/>recognised entity<end/> text text
13:09:22 <fsasaki> christoph: see above XML example. this has to be translated to RDF
13:09:22 <clange> <start id="foo"/>
13:09:31 <clange> <start href="#foo"/>
13:09:41 <fsasaki> ... start and end tags look like the above
13:09:46 <clange> ids or refs (forgot which direction) are in these start/end tags
13:10:30 <fsasaki> christoph: we are using XSLT based tool I developed (trextor) to create RDF. it is quite hard
13:10:39 <clange> krextor
13:10:42 <fsasaki> ... with XPath it is hard to select elements between start and end tags
13:11:03 <fsasaki> ... that is a bit tricky, you need a good knowledge of XPath, the sibling axis' etc.
13:11:59 <fsasaki> ... in context of European project, in which another partner is doing the extraction
13:12:51 <fsasaki> phil: is this similar to Martynas case?
13:13:03 <fsasaki> christopher: in terms of Xpath complexity, yes
13:13:42 <fsasaki> ... general XML to RDF transformation issue?
13:13:42 <fsasaki> https://github.com/fsasaki/its20-extractor/tree/master/wikipedia-extractor
13:13:45 <philr> felix: I've written various converters
13:14:09 <philr> ...it is always special case issues
13:14:37 <philr> ...XML has various ways to include content
13:14:58 <philr> ...special purpose handling is somwhat unavoidable
13:16:16 <philr> ...example documents with guideance would be useful
13:16:36 <fsasaki> .. may be useful to give guidance on how to handle various cases
13:17:45 <fsasaki> christopher: there are patterns, e.g. parent child relations in XML and RDF properties
13:17:57 <fsasaki> ... for this you can provide a high level translation patterns
13:18:12 <philr> clange: High level translation is possible with simple parent-child relationships
13:18:43 <philr> felix: mixture of text and element nodes is challenging
13:19:19 <fsasaki> https://github.com/fsasaki/its20-extractor/blob/master/wikipedia-extractor/its-ta-2-nif-wikipedia.xsl#L43
13:19:54 <clange> fsasaki: handling of specific links (specific to wiki markup)
13:21:00 <fsasaki> phil: in FREME project we are also doing named entity recognition on plain text. our services are capable of returning turtle files, but we can cover many formats
13:22:13 <fsasaki> https://api-dev.freme-project.eu/ckeditor-dev/ckeditor/samples/freme.html
13:25:53 <fsasaki> various types of output, inline or external using json-ld
13:27:15 <fsasaki> action: felix to provide examples of round tripping as done in the freme project
13:27:27 <fsasaki> topic: bdva summit
13:28:48 <philr> felix: to collect information on what better tooling is needed
13:29:04 <philr> ...best practices abd standardization
13:29:20 <philr> ...1.5 hour session on requirements
13:30:04 <philr> clange: is there more I can do if I do not attend the summit?
13:30:25 <philr> felix: it would be good if someone from your organization could attend
13:31:18 <philr> ...questionnaire to bdva members but want input from companies
13:31:54 <philr> Is there a fee to join bdva?
13:32:05 <fsasaki> felix: yes, will send info on that
13:32:19 <clange> fsasaki 14:29: EU is not necessarily interested in new standards being developed, but in existing standards to be _applied_ in a better way
13:32:29 <fsasaki> thanks, clange
13:35:26 <fsasaki> discussion on automationML use case
13:40:25 <fsasaki> felix will send further infos on BDVA around
