Current Broccoli version
Built by Björn beginning of August 2016 (TODO: copy to elba), Wikipedia version from August 2016 (2.8B postings), latest Freebase dump (freebase-rdf-latest, 372M statements extracted a la Freebase Easy).
Start the service on elba
/local/data2/broccoli/16-09-26 ./start.sh
The script contains all files as variables. Changing something (e.g. other custom scores or triple scores should be self explanatory).
For reference (btw: I have no idea how to write proper shellscrips, don't judge 
)

UIMA Chain
For an explanation see Broccoli Uima
Building an Index
First, obtain a Wikipedia XML and a Freebase dump (usually stored in /nfs/raid5/broccoli/...) and make sure these correct files are referenced in broccoli/Makefile and broccoli/freebase/Makefile. Give a proper name to your index using the variable DBTAIL in broccoli/Makefile
Create ontology.txt
If you use an existing RDF3X DB (as usually the case), make sure it is referenced correctly in broccoli/freebase/Makefile and only run (inside the broccoli folder):
make get-freebase-ontology
Otherwise run:
make -C freebase/ build-db
make get-freebase-ontology
Create cas0.zip
Make sure all paths are set correctly in paths.mak
on FILICUDI!! run (in the broccoli fodler)
make deploy-broker
Then, on the server you want to have the reader and writer, run
make deploy-reader
To get things going run the following on as many PC's (and servers) as possible
make deploy-senna
Create a broccoli index
Make sure to copy/move or reference the cas0.zip you built in broccoli/Makefile then run
make build-txt build-index
Start the server
make start PORT=<PORT>
Set up a Broccoli instance for different data
With parts of our chain
Understand the process above and the UIMA framework (see official documentation) and modify accordingly.
From scratch
There is a special folder broccoli/example-data now that has files that can be used as a blue-print for your own data.
Produce the following files:
1. A Knowledge Base file, name: $(DBTAIL)-ontology.txt
Tab-separated, one line per triple: subject<TAB>predicate<TAB>object<TAB>. For example broccoli/example-data/example-ontology.txt:
Björn Buchhold is-a PhD Student . Björn Buchhold is-a Person . Björn Buchhold Country of nationality Germany .
Values use XML Schema notation, e.g.:
Some Song Length "19.0"^^<http://www.w3.org/2001/XMLSchema#float> .
IMPORTANT: The name has to end with -ontology.txt and there has to be at least one triple with a relation is-a and one triple with some other relation (for historical, technical reasons).
2. A file with text postings, named: $(DBTAIL).words-by-contexts.txt
Tab-separated, one line per posting. word<TAB>contextId<TAB>score<TAB>position, entities use underscores for spaces and are prefixed with :e:, e.g.:
this 1 1 0 is 1 1 1 just 1 1 2 an 1 1 3 example 1 1 4 I 2 5 0 :e:Björn_Buchhold 2 5 0 hope 2 1 1 it 2 1 2 helps 2 1 3
3. A file with with info to display for hits, named: $(DBTAIL).docs-by-contexts.txt
Tab-separated, one line per context. contextId<TAB>URL<TAB>Title<TAB>Text to display (positions from wordsfile are separated by @@)<TAB>Which positions belong to the context (used for grey vs black highlighting in the UI)<TAB>context-range (in terms of position for grey/black highlighting in the UI)<TAB>parse-tree<TAB>all-context-boundaries-in-sentence.
The last three columns can be filled with dummy/empty information (contexts 0-maxpos, empty parse tree). The number of tabs must remain the same, though. Maybe the UI needs to be adjusted with an empty parse tree.
See the example.docs-by-contexts.txt for somethind that is rather easy to understand (context 1 has positions 0-5, context 2 has positions 0-3):
1 Example_Document http://example.com This@@ is@@ just@@ an@@ example@@. 0-5 NoParseTree 0-5 1 Example_Document http://example.com I@@ hope@@ it@@ helps@@. 0-3 NoParseTree 0-3
For real-world data with parse-tree information, this can get quite complex (see first sentence in the normal Broccoli data):
1 http://en.wikipedia.org/wiki/Alain_Connes Alain Connes Alain Connes@@ (@@;@@ born@@ 1@@ April@@ 1947@@)@@ is@@ a@@ French@@ mathematician@@,@@ currently@@ Professor@@ at@@ the@@ Collège de France@@,@@ IHÉS@@,@@ The Ohio State University@@ and@@ Vanderbilt University@@. 0-1,7-11,13-17 0_Alain_NNP_*_(S1,(S,(NP_(ENUM,(C,(CH 0_Connes_NNP_*_)_) 1_(_*_*_*_* 2_;_:_*_(S1,(NP_(C* 3_born_VBN_*_(NP_* 4_1_CD_*_*_* 5_April_NNP_*_*_* 6_1947_NN_*_),),)_) 7_)_*_*_*_* 8_is_VBZ_*_(VP_* 9_a_DT_*_(NP,(NP_* 10_French_JJ_*_*_* 11_mathematician_NN_*_)_* 12_,_,_*_*_* 13_currently_RB_*_(ADVP,)_* 14_Professor_NNP_*_(NP,(NP,)_* 15_at_IN_*_(PP_* 16_the_DT_*_(NP,(NP_(ENUM,(C 17_Collège_NNP_*_*_* 17_de_IN_*_*_* 17_France_NNP_*_)_) 18_,_,_*_*_* 19_IHÉS_NNP_*_(NP,)_(C,) 20_,_,_*_*_* 21_The_DT_*_(NP_(C 21_Ohio_NNP_*_*_* 21_State_NNP_*_*_* 21_University_NNP_*_)_) 22_and_CC_*_*_* 23_Vanderbilt_NNP_*_(NP_(C 23_University_NNP_*_),),),),),)_),) 24_._._*_),)_),) 0-1,7-11,13-17;0-1,7-11,13-15,19-19;0-1,7-11,13-15,21-21;0-1,7-11,13-15,23-23;0-0,3-6
4. Create the following empty files
Fill them with actual data if you have it available. It works with empty files (see example-data)
touch $(DBTAIL)-ontology.entity-scores.noabs touch $(DBTAIL)-ontology.name-mapping touch $(DBTAIL)-ontology.reverse-relations
Build an index
Call make build-index and set the variables DATA_DIRECTORY and DBTAIL:
make build-index DATA_DIRECTORY=/home/buchholb/broccoli/example-data DBTAIL=example
Start a server instance
Call make start and set the variables PORT, DATA_DIRECTORY and DBTAIL:
make start PORT=6001 DATA_DIRECTORY=/home/buchholb/broccoli/example-data DBTAIL=example
Deploy a user interface (to a tomcat webserver)
Go to
cd broccoli/userintance
edit the files with your data (adjust: instance name, Tomcat location, maybe username+password, server, port)
vim build.properties vim war/server_properties.xml
compile and deploy
ant build war deploy
Testing if everything works
If you used the files in example-data, a query for PhD-Student occurs-with helps should yield a result.
Image Cache
To add individual images (for demos, needs access to raid so it can write to cache folder, and img has to have a file extension for convert to work, tested on filicudi, does not work on stromboli because code requires Python version >= 3.3):
python3 ~/broccoli/img-hack/image_to_cache.py --mid <MID> --img 'http://...'
Image Service
HiWi project Kai Haase: see Google Doc.
TODO: Florians code has a mechanism for removing outdated images, which also removes images in the cache which now return a 404 not found (which effectively removes all images from the cache after the shutdown of the Freebase API). This should be corrected. Here is the guilty piece of code from https://ad-websvn.informatik.uni-freiburg.de/broccoli/freebase-imgsvc/fbthumbsvc.php:
// If no image could be found (404 error) create a 404 cache file for the
// current id, return a 404 error and end the script.
if ($return_status_code == 404)
{
// If there still was an expired cache file then remove it now!
if ($cachefile_exists)
{
unlink($cachefile_path);
}
// Create a 404 cache file for the current id.
touch($cachefile_path . '_404');
returnMissingError();
}
Mediator Only Index (CIKM)
An index that contains mediators (used for the CIKM presentation) is available in /nfs/raid5/haussmae/demos/broccoli_mediators_no_text
to start (on filicudi, port 7099, should work as any user that can read the files):
/home/haussmae/demos/broccoli_mediators_no_text/ServerMain -p 7099 -o /home/haussmae/demos/broccoli_mediators_no_text/semantic-wikipedia-scientists-ontology -s /home/haussmae/demos/broccoli_mediators_no_text/semantic-wikipedia.stop-words /home/haussmae/demos/broccoli_mediators_no_text/semantic-wikipedia-scientists -m /home/haussmae/demos/broccoli_mediators_no_text/semantic-wikipedia-scientists-ontology.url-mapping
The user interface for backend filicudi:7099 is available at http://filicudi.informatik.uni-freiburg.de:6222/BroccoliCIKM (no UI hack) and http://filicudi.informatik.uni-freiburg.de:6222/BroccoliCIKM2 (UI hack). The UI hack makes specific mediator names readable in the query graph (and only there). The hack adjusts the nameLabel variable in the File src/de/uni/freiburg/broccoli/client/ui/BreadcrumbLabel.java of userinterface (in the broccoli respository).
