Associating Cooking Video Segments with Preparation Steps
We are trying to integrate television cooking videos with corresponding cookbooks. The cookbook has the advantage of the capability to easily browse through a cooking procedure, but understanding of actual cooking operations through written explanation is difficult. On the other hand, a video contains visual information that text cannot express sufficiently, but it lacks the ease to randomly browse through the procedures. We expect that their integration in the form of linking preparation steps (text) in a cookbook and video segments should result in complementing the drawbacks in each media. In this work, we propose a method to associate video segments with preparation steps in a supplementary cookbook by combining video structure analysis and text-based keyword matching. The result of an experiment showed high accuracy in association per video segments, i.e. annotating the video.

Automatic Video Indexing Based on Shot Classification
Automatic indexing to video data is in strong demand to cope with the increasing amount. We propose an automatic indexing method for television news video, which indexes to shots considering the correspondence of image contents and semantic attributes of keywords. This is realized by first, (1) classifying shots by graphical feature, and (2) analyzing semantic attributes of accompanying captions. Next, keywords are selectively indexed to shots according to appropriate correspondence of typical shot classes and semantic attributes of keywords. The method was applied to 75 minutes of actual news video, and resulted in indexing successfully to approximately 50% of the typical shots (60% of the shots were classified as typical), and 80% of the typical shots where captions existed.

Implementation of Temporal Logic Programming Language Tokio
The temporal logic programming language, "Tokio" can be executed by a resolution of Interval Temporal Logic. The resolution consists of three parts, which are: the unification of the temporal variable, reduction including temporal operator, and interval control. The implementation of Tokio includes automatic interval length determination and stream-like temporal variable representation. At the end of this report, an abbreviated version of a Tokio interpreter written in Prolog will be shown.

Relational Algebra Machine GRACE
Most of the data base machines proposed so far which adopts a filter processor as their basic unit show poor performance for the heavy load operation such as join and projection etc., while they can process the light load operations such as selection and update for which a full scan of a file suffices. These machines which incorporates n processors takes it O(N*M/n) time to execute join of two relations whose cardinalities are N and M respectively.

Multimedia Integration for Cooking Video Indexing
We have been working on the integration of video with supplementary documents, such as cooking programs. We propose an integration system that performs semantic segmentations of video and text and associates them together. This association is realized using the ordinal restriction of the recipe, cooccurrences of words in the text and the audio in the video, and the relation between the background in a video and words which describe the situation in a text. In this paper, we will introduce the result of an evaluation experiment and show the effectiveness of the proposed integration method. Through our method, many applications should become possible, such as a cooking navigation software.

An object-oriented distributed system integrating multimedia resources
A distributed system is introduced which provides extensible as well as integrated environments for users and applications programs to access and combine distributed resources conveniently. The system is based on the concept of object-oriented service bases. Distributed resources are abstracted as objects containing the metainformation of the resources. A service base in each node is constructed to manage these objects. There are three layered views (external, conceptual, and internal) of objects. A service base can be seen as a software package built on an existing operating system to provide mapping from the external view of objects to the internal view to realize transparency and to absorb heterogeneity and different media types. The modeling and an implementation of this distributed system are presented.<<ETX>>

Interval priorities in AHP by interval regression analysis
Abstract This paper proposes an interval approach for obtaining interval weights of priorities in the analytic hierarchy process (AHP) reflecting inconsistency of pairwise comparison ratios given by a decision maker. Even if pairwise comparison values with respect to preference are given as crisp values, the priority weights should be estimated as intervals because of a decision maker's uncertainty of judgments. We deal with two types of comparison matrices represented as crisp and interval elements. This allows some uncertainty of estimations made by a decision maker. The proposed approach can obtain the estimated interval priorities. Since interval regression analysis is based on the concept of possibility, the interval weights obtained by the proposed method can be interpreted as the possible ranges estimated from the given data. The sum of widths of the obtained intervals can be regarded as the degree of inconsistency included in the given data. It is emphasized that interval data of preference can obtain the lower and upper models for the estimated weight intervals.

Improving Back-Transliteration by Combining Information Sources
Transliterating words and names from one language to another is a frequent and highly productive phenomenon. Transliteration is information loosing since important distinctions are not preserved in the process. Hence, automatically converting transliterated words back into their original form is a real challenge. However, due to wide applicability in MT and CLIR, it is a computationally interesting problem. Previously proposed back-transliteration methods are based either on phoneme modeling or grapheme modeling across languages. In this paper, we propose a new method, combining the two models in order to enhance the back–transliterations of words transliterated in Japanese. Our experiments show that the resulting system outperforms single-model systems.

Plantio: an interactive pot to augment plants' expressions
This paper introduces an interactive pot called "Plantio" which realizes hybridization between plants and electronic computing system. The goal for this research is to create an intimate relationship between human and plants. Plantio represents plants' biopotentials changed by surroundings, and it makes various expressions according to daily interactions with human. Plantios' representation begins to have individuality as it interacts with users and environments.

Concept and prototype of protein-ligand docking simulator with force feedback technology
A novel concept for a protein-ligand docking simulator using Virtual Reality (VR) technologies, in particular the tactile sense technology, was designed and a prototype was developed. Most conventional docking simulators are based on numerical differential calculations of the total energy between a protein and a ligand. However, the basic concept of our method differs from that of conventional simulators. Our design utilizes the force between a ligand and a protein instead of the total energy. The most characteristic function of the system is its ability to enable the user to 'touch' and sense the electrostatic potential field of a protein molecule. The user can scan the surface of a protein using a globular probe, which is given an electrostatic charge, and is controlled by a force feedback device. The electrostatic force between the protein and the probe is calculated in real time and immediately fed back into the force feedback device. The user can easily search interactively for positions where the probe is strongly attracted to the force field. Such positions can be regarded as candidate sites where functional groups of ligands corresponding to the probe can bind to the target protein. Certain limitations remain; for example, only twenty protein atoms can be used to generate the electrostatic field. Furthermore, the system can only use globular probes, preventing drug molecules or small chemical groups from being simulated. These limitations are the result of our insufficient computer resources. However, our prototype system has the potential to become a novel application method as well as being applicable to conventional VR technologies, especially to force feedback technologies.
