abstract = {This paper explores the inte­gra­tion of geo-spa­tial data into RDF (Resource Descrip­tion Frame­work) using Apache Jena, a pop­u­lar Java-based frame­work for build­ing Seman­tic Web appli­ca­tions. We explain the basic rep­re­sen­ta­tion of geo-spa­tial data in RDF with a focus on both the new GeoSPAR­QL 1.1 stan­dard and Apache Jena. Our inves­ti­ga­tion cov­ers advanced tech­niques, such as trans­for­ma­tion of coor­di­nate ref­er­ence sys­tems, aggre­ga­tion of geo-spa­tial data, cre­ation of new geo-objects, and sim­pli­fi­ca­tion of poly­gons. Addi­tion­al­ly, we dis­cuss the usage of the H3 Grid as a Dis­crete Glob­al Grid Sys­tem (DGGS) for geo-spa­tial con­ver­sion. Fur­ther­more, we present per­for­mance opti­mi­sa­tions spe­cif­ic to Apache Jena, includ­ing per-graph geo-index­ing, improved geo-index seri­al­iza­tion for faster start­up times, and man­u­al opti­mi­sa­tion of geo-spa­tial queries. We con­clude with a com­par­i­son of dif­fer­ent geo-func­tions and out­line future direc­tions for enhanc­ing geo-spa­tial data man­age­ment in RDF.},

abstract = {In the con­text of cri­sis infor­mat­ics, the inte­gra­tion and exploita­tion of high vol­umes of het­ero­ge­neous data from mul­ti­ple sources is one of the big chances as well as chal­lenges up to now. Seman­tic Web tech­nolo­gies have proven a valu­able means to inte­grate and rep­re­sent knowl­edge on the basis of domain con­cepts which improves inter­op­er­abil­i­ty and inter­pretabil­i­ty of infor­ma­tion resources and allows deriv­ing more knowl­edge via seman­tic rela­tions and rea­son­ing. In this paper, we inves­ti­gate the poten­tial of rep­re­sent­ing and pro­cess­ing geospa­tial infor­ma­tion with­in the seman­tic par­a­digm. We show, on the tech­ni­cal lev­el, how exist­ing open source means can be used and sup­ple­ment­ed as to effi­cient­ly han­dle geo­graph­ic infor­ma­tion and to con­vey exem­plary results high­ly rel­e­vant in con­text of cri­sis man­age­ment appli­ca­tions. When giv­en seman­tic resources get enriched with geospa­tial infor­ma­tion, new infor­ma­tion can be retrieved com­bin­ing the con­cepts of mul­ti-poly­gons and geo-coor­di­nates and using the pow­er of GeoSPAR­QL queries. Cus­tom SPARQL exten­sion func­tions and data types for JSON, XML and CSV as well as for dialects such as Geo­J­SON and GML allow for suc­cinct inte­gra­tion of het­ero­ge­neous data. We imple­ment­ed these fea­tures for the Apache Jena Seman­tic Web frame­work by lever­ag­ing its plu­g­in sys­tems. Fur­ther­more, sig­nif­i­cant improve­ments w.r.t. GeoSPAR­QL query per­for­mance have been con­tributed to the frame­work.},

@article{stadler2020facete,
abstract = {In this work, we present a schema-agnos­tic faceted brows­ing bench­mark gen­er­a­tion frame­work for RDF data and SPARQL engines. Faceted search is a tech­nique that allows nar­row­ing down sets of infor­ma­tion items by apply­ing con­straints over their prop­er­ties, where­as facets cor­re­spond to prop­er­ties of these items. While our work can be used to realise real-world faceted search user inter­faces, our focus lies on the con­struc­tion and bench­mark­ing of faceted search queries over knowl­edge graphs. The RDF mod­el exhibits sev­er­al traits that seem­ing­ly make it a nat­ur­al foun­da­tion for faceted search: all infor­ma­tion items are rep­re­sent­ed as RDF resources, prop­er­ty val­ues typ­i­cal­ly already cor­re­spond to mean­ing­ful seman­tic clas­si­fi­ca­tions, and with SPARQL there is a stan­dard lan­guage for uni­form­ly query­ing instance and schema infor­ma­tion. How­ev­er, although faceted search is ubiq­ui­tous today, it is typ­i­cal­ly not per­formed on the RDF mod­el direct­ly. Two major sources of con­cern are the com­plex­i­ty of query gen­er­a­tion and the query per­for­mance. To over­come the for­mer, our frame­work comes with an inter­me­di­ate domain-spe­cif­ic lan­guage. There­by our approach is SPAR­QL-dri­ven which means that every faceted search infor­ma­tion need is inten­sion­al­ly expressed as a sin­gle SPARQL query. In regard to the lat­ter, we inves­ti­gate the pos­si­bil­i­ties and lim­its of real-time SPAR­QL-dri­ven faceted search on con­tem­po­rary triple stores. We report on our find­ings by eval­u­at­ing sys­tems per­for­mance and cor­rect­ness char­ac­ter­is­tics when exe­cut­ing a bench­mark gen­er­at­ed using our gen­er­a­tion frame­work.
