This paper introduces a novel conceptual framework to support the creation of knowledge representations based on enriched Semantic Vectors, using the classical vector space model approach extended with ontological support. One of the primary research challenges addressed here relates to the process of formalization and representation of document contents, where most existing approaches are limited and only take into account the explicit, word-based information in the document. This research explores how traditional knowledge representations can be enriched through incorporation of implicit information derived from the complex relationships (semantic associations) modelled by domain ontologies with the addition of information presented in documents. The relevant achievements pursued by this work are the following: (i) conceptualization of a model that enables the semantic enrichment of knowledge sources supported by domain experts; and (ii) implementation of a proof-of-concept, named SENSE (Semantic Enrichment knowledge Sources).

Conflict Mitigation

AbstractLarge-scale engineering projects typically involve many different types of professionals who must interact and communicate with one another. This interaction produces conflicts that need to be resolved. A framework is presented in which the rationale used in a collaborative design environment for designing an artifact is also used for conflict mitigation. The framework contains mechanisms for checking interactions and prompting hypotheses about the reasons for the interactions. These hypotheses, once verified by the designers, improve conflict resolution by assisting them in coordinating and negotiating conflicts. This, in turn, enhances communication during the design process and consequently increases productivity in the engineering industry.

The separation wall, one of the largest civil engineering projects in Israel's history, has been criticized even by the U.S. administration, with Condoleezza Rice stating at the end of June 2003 that it ““arouses our [U.S.] deep concern”” and President Bush on 25 July calling it ““a problem”” and noting that ““it is very difficult to develop confidence between the Palestinians and Israel with a wall snaking through the West Bank.”” A number of reports have already been issued concerning the wall, including reports by B'Tselem (available at www.btselem.org), the UN Office for the Coordination of Humanitarian Affairs (available at www.palestinianaid.info), and the World Bank's Local Aid Coordination Committee (LACC; also available at www.palestinianaid.info). UNRWA's report focuses on the segment of the wall already completed and is based on field visits to the areas affected by the barriers, with a special emphasis on localities with registered refugees. Notes have been omitted due to space constraints. The full report is available online at www.un.org/unrwa.

Studies on knowledge creation are limited in general, and there is a particular shortage of research on the topic in small and medium-sized enterprises (SMEs). Given the importance of SMEs for the economy and the vital role of knowledge creation in innovation, this situation is unsatisfactory. Accordingly, the purpose of our study is to increase our understanding of how SMEs create new knowledge. Data are obtained through semi-structured interviews with ten managing directors of German SMEs operating in the building and construction industry. The findings demonstrate the influence of external knowledge sources on knowledge creation activities. Even though the managing directors take advantage of different external knowledge sources, they seem to put an emphasis on informed knowledge sources. The study´s findings advance the limited body of knowledge regarding knowledge creation in SMEs.
