amalgame's Issues

Strategy with descendents makes amalgame hang

At http://87.106.253.23/amalgame/amalgame/app/build?strategy=http://localhost/ns/strategy5, we defined a strategy which uses structure/descendent.

What we tried to accomplish here was: Use the source vocab SDMX, map it to the "Descriptors" part of STW, then use the the result for mapping SDMX to STW Thsys part (connected to the descriptors via skos:narrower)

When we try to display the resulting set (B. dataset43), Amalgame hangs - wheel spinning, other commands still work. The log shows:

Crash when loading a vocabulary

In a newly set up instance of amalgame (5fc88e3), the instance crashes when I try to load a small vocabulary from a local file. Last log entry is:

/Fri Apr 10 13:00:59 2015/ request(54, 1428663659.506, [session('adff-d548-4689-2b7c.s279606780'),peer(ip(127,0,0,1)),method(post),request_uri('/amalgame-sdmx/servlets/uploadData'),path('/amalgame-sdmx/servlets/uploadData'),http_version(1-1),host('127.0.0.1'),port(30202),user_agent('Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0'),dnt('1'),referer('http://111.111.111.111/amalgame-sdmx/user/loadFile'),cookie([swipl_session='adff-d548-4689-2b7c.s279606780']),content_type('multipart/form-data; boundary=---------------------------562544013346'),x_forwarded_for('134.245.95.1'),x_forwarded_host('111.111.111.111'),x_forwarded_server('example.com'),connection('Keep-Alive'),content_length(26264)]).

(Addresses obfuscated).

Maybe this is somehow related to #10

Type selector not working?

I tried to “select facet on type” to get concepts of a certain subclass of skos:Concept, but invariably get 0 concepts in the resulting set.

I double checked that the classes are present in the data, and could reproduce it with inserting

skos:Concept, and

http://www.w3.org/2004/02/skos/core#Concept

into the class input field.

The vocabularies I checked with were:

http://zbw.eu/stw/versions/latest/download/stw.ttl.zip (selecting http://zbw.eu/namespaces/zbw-extensions/Thsys)

http://purl.org/linked-data/sdmx/2009/subject# (selecting skos:Concept)

Hanging at 100% CPU

With two different vocabularies, Thesoz and Eurovoc, matching to STW, I encountered situations where CPU goes up to 100% and stays there. This occurs after having applied string/label (exact) matches to almost the whole sets, after I clicked on the newly created dataset bubble. After 5 min obviously a timeout occurs, but the characteristics of the dataset are not displayed, and when I click again, CPU for swipl again goes to 100%.

Memory VSIZE of the 4GB Centos-6.5 machine is 1.5 GB. There seems to be no disk activity during the time.

Search on SDMX side of Amalgame doesn't work

At http://87.106.253.23/amalgame/amalgame/app/build?strategy=http://localhost/ns/strategy4 I started a manual correspondence evaluation. On the STW side the search works (screenshot 1), but it doesn't on SDMX side (screenshot 2).

Project home page 404 Not Found

The project link http://semanticweb.cs.vu.nl/amalgame/ (at the top of Amalgame's GitHub page) returns 404 Not Found.

Feature request: User interface for manually adding correpondences

This should allow domain experts correspondences which are not derived from some mapping, but only from their off-band vocabulary and domain knowledge.

Could you tell me what I'm doing wrong?

Server error on publish

After having evaluated the results of a strategy, I hit "publish" and then "Go", (accepting the defaults). What I get is a system error:

Default threshold for string/similarity matcher

Currently, the default for the edit distance threshold is 0.0. Why not set this to a reasoable value, e.g. 0.7? This would give users a glue, and it could prevent expensive Cartesian product computation and display if they don't change the default.

Error 500 in all mapping strategies on get /amalgame/amalgame/data/nodelist

In all mapping strategies, we consistently encounter errors when we click on datasets: The application seems to hang, in the log we see messages as below.

This occurs after cpack_upgrade. and make., and after multiple new starts of swipl-httpd.

No idea what's wrong ...

I just wanted to try if the solution of #7 is in the current cpacks. Executing cpack_upgrade yielded

%  create mode 100644 lib/amalgame/ag_strategy.pl

Now, we can invoke amalgame, however we cannot select a dataset for evaluation.

How to create a new mapping relation manually?

We tried to create new mapping relations manually: E.g.,

smdx:"Agriculture, forestry, fisheries" skos:narrowMatch stw:"W.02 Forestry"

We chose to evaluate an already existing mapping and started with the already suggested and confirmed relation

smdx:"Agriculture, forestry, fisheries" skos:narrowMatch stw:"W.01 Agriculture"

After looking up "W.02 Forestry" on the righthand side of the mapping screen, we got this display:

where the displayed graphics (below "2 individual motivations" seem not consistent with the selected concept and its URI). Anyway, we selected "narrower" and submitted.

What happend is that the new relation was saved, but the original narower relation (to stw:"W.01 Agriculture") was reset to evaluator:unrelated.

We could not yet figure out how to create new relations (out of just our heads) without hurting existing ones.
