DBPedia earthsciences
Skill Cartridge®
Built on the vocabulary from DBPedia on geology and neighboring fields and powered by TEMIS' Smart Term Facilitator (STF) technology.


The STF DBPedia earthsciences Skill Cartridge® extracts topics around geology, mining and related fields from text. It is built on a subset of more than 14000 concepts and over 45000 synonyms from DBPedia as of January 2013 and their taxonomic information.


Powered by Smart Taxonomy Facilitator (STF) technology, The STF DBPedia earthsciences Skill Cartridge® contains more than 14000 concepts and over 45000 synonyms from DBPedia on geology and related fields. Information on taxonomic embedding as well as the DBPedia URI for each concept is retained. Each resulting term receives a confidence score representing to what degree it appears as an appropriate topic or index term for the document.

The Skill Cartridge® is compiled for the english language.

The topics modelled in this Skill Cartridge® include but are not limited to:

• Geology

• Geodesy

• Geophysics

• Mining

• Mineralogy

• Meterology

So topics like Fracking, OGC Reference Model, MapDotNet or Mackinawite are modelled as are many tens of thousands of other terms.

STF technology adds two distinctive features to the thesaurus-based extraction :

- Fuzzy Term Matching that produces and recognizes variants of thesaurus terms, minimizing silence and increasing recall

- Relevance Scoring, that evaluates the contextual relevance of each recognized term, discarding the less relevant ones improving precision. Relevance Scoring exploits a range of heuristics, including statistics and part-of-speech tagging .

Customization and Extension

The Skill Cartridge® can be easily customized by tuning the STF parameters on the specific way of scoring results, on the required maximal amount of terms to return, their minimal confidence score, their minimal string distance to known thesaurus terms and many others.

Typical Applications

Typical use cases for the STF DBPedia earthsciences Skill Cartridge® include

- Automated indexing of documents in corresponding geology and related fields

- Creation of hierarchical facets for enhancing search and browsing

- Document recommendations based on indexed terms

- Design of topical collections or Topic Pages focusing on specific thematic hierarchies in geology and related fields
