KODAR: Clustering application

The aim of this application is to discover potential areas of knowledge and similar research areas based on keywords of research papers.

Data

The data is extracted from an SPARQL endpoint:

You could execute this query to get last results:

PREFIX dct: <http://purl.org/dc/terms/>
PREFIX bibo: <http://purl.org/ontology/bibo/>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>

SELECT ?name ?author  ?publication ?title (group_concat(distinct ?keyword;separator=", ") as ?keywords)
WHERE {
  graph <http://ucuenca.edu.ec/wkhuska> {
  	?author foaf:name ?name.
	?author foaf:publications ?publication.  
	?publication dct:title ?title.
  	?publication bibo:Quote ?keyword.
  }
} GROUP BY ?name ?author  ?publication ?title
PREFIX dct: <http://purl.org/dc/terms/>
PREFIX bibo: <http://purl.org/ontology/bibo/>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>

SELECT distinct ?name ?author ?publication (group_concat(distinct ?tit;separator = ",") as ?title)  (group_concat(distinct ?keyword;separator=",") as ?keywords)
FROM <http://ucuenca.edu.ec/wkhuska>
WHERE {
  ?author foaf:publications ?publication.  
  ?author foaf:name ?name.
  ?publication bibo:Quote ?keyword.
  ?publication dct:title ?tit.
} GROUP BY ?author ?publication ?name
