title: “All you can eat” ontology-building: Feeding Wikipedia to Cyc

authors: Sarjant, Samuel

subjects: ontologies

abstract: In order to achieve genuine web intelligence, building some kind of large general machine-readable conceptual scheme (i.e. ontology) seems inescapable. Yet the past 20 years have shown that manual ontology-building is not practicable. The recent explosion of free user-supplied knowledge on the Web has led to great strides in automatic ontology building,
but quality-control is still a major issue. Ideally one should automatically build onto an already intelligent base. We suggest that the long-running Cyc project is able to assist here. We describe methods used to add 35K new concepts mined from Wikipedia to collections in ResearchCyc entirely automatically. Evaluation with 22 human subjects shows high precision both for the new concepts’ categorization, and their assignment as individuals or collections. Most importantly we show how Cyc itself can be leveraged for ontological quality control by ‘feeding’ it assertions one by one, enabling it to reject those that contradict its other knowledge.

title: Coupled flow-wave numerical model in assessing the impact of dredging on the morphology of Matakana Banks

authors: Ramli, Andi Yulianti

subjects: ebb-tidal delta

abstract: The short- and long-term impacts of dredging on the Matakana Banks ebb-tidal delta was investigated by numerical modelling using Delft3D. The model covered dredging locations inside Tauranga Harbour and the offshore areas around the Matakana Banks ebb-tidal delta, and was calibrated by an extensive field programme to measure hydrodynamic processes and sediment characteristics, and high resolution bathymetric surveys. The impacts of dredging was then investigated by modelling three different conditions: (1) before dredging started in 1968, using 1967 bathymetry; (2) the present situation using 2013 bathymetry with existing dredging and dumping; and (3) future scenarios using 2013 bathymetry with alternative offshore disposal locations. 
The field data and hydrodynamic model results showed that the ebb-tidal delta can be separated into two main regions that are dominated by tidal processes or wave processes. Overall, the wave influence becomes more dominant as the distance from the entrance channel (main ebb jet) increases, and vice versa for tidal processes. Sediment transport pathways were inferred using spatial patterns of erosion and accretion from bathymetric surveys and cross-sectional profiles along the shoreline. The pathways reflected the interactions between the identified wave and tide processes. 
A month-long time series of wave conditions were used to force a wave model coupled with the hydrodynamic model for the 2013 bathymetry to simulate the present day situation. The results showed that the sediment volume of the ebb-tidal delta fluctuated with tidal range; accretion occurred during neap tides and erosion during spring tides. To assess the long term impact, the morphological factor (morfac) tool in Delft3D was used. Morfac of 60 was applied for 12 days simulation time and the results will be presented in this paper

title: The use of Māori mythology in clinical settings: Training issues and needs

authors: Cherrington, Lisa

subjects: Maori

abstract: Within therapeutic settings, narrative
approaches are increasingly being used as a
way of creating new understandings and
new stories. This paper discusses the use of
purakau as a Māori focused intervention
when working with Māori tangata whaiora
(clients) and their whānau. This paper will
outline the rationale and relevance of using
purakau with Māori. However, the
emphasis is on the training provided to
clinicians in the use of purakau. An outline
of the training process is provided. In
doing so, issues regarding the use of these
taonga (treasures) in clinical psychology
will be raised. It will be argued that Māori
mythology must have a place in the kete of
Māori psychology.
