Patrick, Lars, First, I wanted to comment on Patrick's Blog post, but it doesn't allow comments for posts older than 2 days. On Fri, Jan 28, 2011 at 5:21 PM, Lars Heuer <[email protected]> wrote: > Hi Patrick, > > [...] >> Aki has a good point that occurrence data in such an topic map SQL dump >> can be the *starting point for further refinement.* And he actually >> posted refinement data to Maiana. > > Yes, I think that's the right direction. I also think that's the right direction - without even having a closer look at it. Let me bring some light on how it all started. One day somebody¹ came into my office (which I share with Thomas) and disrupted us from our work, like it happens every day. He talked about this hot Wikileaks thing everybody is writing about and what effort it would be to get it into a topic map, i.e. not do anything to it except making it available somehow. Our answer was short: close to none: Download the CSV, run some regular expressions on it, save it as CTM and upload it to Maiana. Done in a few minutes by a student assistant. While gazing at the horrible result, he found that there are many typos, even in the category names, so he decided to load the CSV into Freebase Gridworks (which is called Google Refine nowadays) and export it from there to CTM which was done in a few minutes, too². He uploaded it to Maiana again, wrote a short note to the "somebody" mentioned above and then he continued reading papers for his thesis. ¹ you may guess who it was but not publish it :P ² If I remember correctly, the only things which thwarted him for a second was strange literal escaping and the use (and even inconsistent use) of literals in CTM. >> Sure, I think the TopicMaps Lab should be the origin of such refinement >> but apparently they have other priorities. Indeed they have. > Apparently some see a value in the topic map as it is otherwise they > wouldn't peddle around with it. Indeed somebody sees a value in it. People are even writing mails and ask us to present it on conferences. The main point of the talk we're going to give is not how great the result is but the little effort which was needed to obtain it. I guess Aki and Lars each spent 10 times more time on thinking about it than Thomas and I spent on it together. Now where are your 10 times better results, Lars? I can see Aki's. > That point leads me to my initial question: How could Der Spiegel > could have benefited from the topic map? I'd be glad it someone of the > creators would stand up for the thesis they brought up. Probably not so much with this half-an-hour-exercise conversion. But the above-mentioned "somebody" had the idea of putting additional data into the same topic map: The major cities and their geo coordinates. This completely separate additional data didn't even trigger any merging, but it provided a tiny bit of added value nevertheless: %prefix wds http://psi.topicmapslab.de/wardiary/schema/ for $r in fn:coordinates-in-distance( "Kabul" << atomify tm:name << characteristics / wds:coordinates , 30 ) return $r << characteristics / wds:hostnationwia One could e.g. query for host nation WIA incidents near Kabul directly without having to look in one place to get the coordinates of Kabul and then put them into a query. Instead of looking for things which have the name Kabul and getting it's coordinates, one could also just use e.g. the geonames identifier. Compared to simple text mining, this would also incidents where Kabul is not mentioned in the description. Of course this could be done with many other technologies, too. The benefit compared to CSV and an SQL dump is just having all your additional knowledge in one place and being able to combine it. Or is there anything on the web where a non-technical person can upload SQL dumps and/or CSV dumps and do structured queries on it? By the way: With these few steps of adding identifiers to CSV cells we improved queryability and therfore made the data available to the LOD who can use the Sparql end point. What are your 3 steps in less than 30 minutes to convert the raw data into linked open data? What could Spiegel have done? I guess they may have a map of census data for larger cities there. Or maybe the locations of whereabouts of their reporters. Just throw this data into the topic map and run some useful queries. Build hypotheses based on the statistics, verify it according to matching incidents or see that it doesn't hold against the reports. It took a while to write down this E-Mail, so maybe I'm now on par with Lars' efforts on (working on UNION discussing) the AWD map. Now what about your results, Lars? One remark regarding Lars' and Robert's remarks on how to not model a topic map: We all know and agree that a 1:1 mapping of relational data is not what one may considers a beautiful topic map, but who except you cares? It's the same question as if the TMDM is beautiful or not. Most people (except maybe the readers of this mailing list) do not have their mental models in terms of a topic map. People like lists of data and tables of data. That's one reason they use these structures all the time. (The other is: they are used to the tools which provide easy working with these structures.) Just transforming easy-to-grasp table-like data into a graph does not provide much value either (or at least it wouldn't be worth the effort needed with currently available tools). Topic Maps come handy when you want to describe the existing structure (i.e. the 1:1 mapping) and match it with other existing structures (i.e. other 1:1 mappings). I think nobody want's to spend hours of time to transform data to another structure in the hope of maybe better results. It also cannot easily be done automatically. I'm not a reporter and not really interested in the incidents themselves, so I won't spend a lot of time in unearthing subliminal data. In my point of view, it was just a quick exercise to see how fast it can be done and how the tools available perform.
