Improving information searching beyond full text retrieval requires both appropriate document representation and document management. This research project develops a new infrastructure and environment for Thai Text Retrieval. It has been created by integrating Active Hypermedia Delivery System (AHYDS) with Natural Language Processing (NLP) techniques. NLP techniques are applied to enhance document processing to obtain an appropriate document representation. The AHYDS architecture provides a framework for open data delivery service with quality.

Our method combines the photogrammetric map created from aerial photographs with photographs taken by the general public. The former gives the surface, while the latter gives the texture, and we make a 3D model step-by-step based on a semiautomatic process. We applied this method to the 3D reconstruction of the citadel of Bam, which is a collapsed historical site by the earthquake. Available photographs are limited because new images cannot be captured after the collapse, but we successfully produced a 3D model of the site with texture taken from the photograph. Our system is based on 3ds Max software with several MAXScript tools, such as automatic tools for generating mesh surface from wireframe by assuming walls, slopes and grounds, and assistance tools for a semi-automatic process of estimating camera parameters and transformation matrix.

The concept of multidimensional data is an effective approach to reduce the complexity of structural access management. As XML becomes a key point both for data representation and transactions, it is necessary to investigate all improvements related to DBMS’s that pertain to these areas. The data used in our research is taken from the geomedia world, where the content is a mix of geographic and cultural multimedia information. We add multidimensional features into XMLin order to be able to deal with, and take advantage of, various user properties, such as language. This technique enables us, for instance, to offer efficient multilingual support. Focusing on XML, this paper investigates multidimensional indexing methods and introduces a new operator to include these new models into the Phasme information engine prototype.

Our approach to the notion of context is unique in terms of the proposal of the model of context from the viewpoint of database systems and informatics. We assume that content is actually comprised by two basic elements, namely context-free content and context-sensitive content, of which the latter is usually neglected in traditional database systems. We further propose that the context-sensitive part can be further decomposed into two elements, namely relationship and arrangement. Then we discuss some examples about how we can reformulate the context using various operations, and this arguments leads to the new line of database design, namely context-based database systems with the new design of a query language. Finally we introduce our ongoing digital archiving project called Toyo Bunko Image and Manus...

Further definition of relationship functions between entities -or terms with related attributes- are shown by a visual graph or simple formula. Domain dependent designs of relationship as a part of ontology development for the selected corpus, and based on it implementation of tools like protégé are presented. It concludes with conceptual sketch of one application of this model for layout learning semantic information access of the architectural corpora.

This model -domain ontology- provides systematic lexical specification of the components and the relationship links between them that reflects 3 dimensional characteristics of the architectural content for a typology of historical buildings, caravanserais of the Silk Roads. This paper discusses issues about design and data input of the lexical model, specially the multilingual terminology. Further as the process of defining relationships is the main focus of developing a spatial ontology model, this paper will review the necessary background knowledge and the contribution of architectural domain for collecting and creating relationship links in order to cover the attributes of architectural space and the constraint...

The specification of a unified lexical model for covering semantic of multilingual terminology developed in protégé is presented as far as shortcoming of this tool for multilingual and remote collaborative support.

At first, it was thought that the principal cause of the heat island was the large thermal inertia of the surface at the city comparing with suburbs. However, when it came to be able to measure the surface temperature at the ground level using the remote sensing technique by 1970's, the daily surface temperature fluctuation in the city part was revealed to be larger than that of suburbs. This fact indicated that the surface of the city part had small thermal inertia, and the explanation by the thermal inertia model failed if this was simply interpreted. We have observed the surface air temperature and the radiation balance of the Kyoto city from 2004 to 2006 at more than 30 points. The data showed clear heat island at the central city area in the nighttime, while no temperature differences are observed in the daytime. Using data when the radiation balance was abruptly changed by...

This paper briefly summarizes our nearly eight years of effort for post-disaster reconstruction of Bam Citadel. The paper starts with the framework of the project that consists of architectural process and conceptual process and we discuss the design of workflow for efficient reconstruction process. Architectural process is discussed in terms of accuracy requirement of modeling, comparison of manual, semi-automatic and automatic modeling, and rendering of the model using a 3D CG tool such as 3ds Max. Conceptual process is also discussed in terms of designing our knowledge about Bam using ontology, and Web framework for navigating the knowledge base.
