By Thepchai Supnithi, Takahira Yamaguchi, Jeff Z. Pan, Vilas Wuwongse, Marut Buranarach

This e-book constitutes the complaints of the 4th Joint foreign Semantic know-how convention, JIST 2014, held in Chiang Mai, Thailand, in November 2014.

The subject of the JIST 2014 convention was once "Open info and Semantic Technology". JIST 2014 convention consisted of major technical tracks together with general paper song (full and brief papers), in-use song and particular music, poster and demo consultation, workshops and 4 tutorials. The 32 papers during this quantity have been rigorously reviewed and chosen from seventy one submissions. The paper subject matters are divided into 8 different types: ontology and reasoning, associated info, studying and discovery, rdf and sparql, ontological engineering, semantic social net, seek and querying, and purposes of semantic technology.

Keywords: DL-Lite 1 · Ontology · Debugging · MIPS · Graph Introduction Ontologies play an important role in the semantic web, as it allows information to be shared in a semantically unambiguous way. However, the development and maintenance of an ontology are complex and error-prone. Thus, an ontology can easily become logically inconsistent. Ontology debugging [14], which aims to pinpoint the causes of logical inconsistencies, has become one of key issues in ontology engineering. t. an unsatisfiable concept [9,12,14] or compute minimal incoherence preserving subterminology (MIPS) of an ontology [12,18].

Proof. According to Theorem 4, n ∈ descendants(S, GT ) denotes n S. Thus, in the steps 4-6 of algorithm 1, n1 = n2 means that there exists a path pair from node n1 (or n2 ) to disjointness pair(S, ¬S). By definition 4, these two paths consist in a MIPP. By applying algorithm 2, we can transform a MIPP into a MIPS. For any MIPS in T , there exists a concept(or role) that is subsumed by two disjointness concepts(or roles). Thus, from Theorem 4, we can get two intersectional path derived from two disjointness node in GT .
