Compilation of dictionaries for semantic attribute analysis of television news captions
With the increase in the amount of video that is broadcast daily, there is an increasing need for storage of video in a systematic way for future reuse and retrieval. In particular, from the viewpoint of importance and usability, it is desirable to index news videos. For adequate automatic indexing based on the text information in the video, it is not sufficient to apply the simple index extraction and annotation methods which have been widely used in conventional methods. It is important to select index candidates with reference to semantic attributes. The purpose of this study is to compile dictionaries which are needed for analyzing the semantic attributes of captions (noun phrases) in TV news videos. We describe the process by which words are extracted from text corpora and a thesaurus for storage on the basis of specified conditions. The quality of the dictionaries is examined by analysis of the semantic attributes of the words appearing in actual news videos, and the results are presented. In evaluation experiments in which an existing proper noun dictionary and temporal noun dictionary were combined and used, a recall of 79 to 93% and a precision of 41 to 71% were obtained. Although the precision is low in this result, it is concluded that the compiled dictionaries are of practical use for indexing since the recall is more important in that case. © 2003 Wiley Periodicals, Inc.

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.

Complexity Analysis of a Cache Controller for Speculative Multithreading Chip Multiprocessors
Although many performance studies of memory speculation mechanisms in speculative multithreading chip multiprocessors have been reported, it is still unclear whether the mechanisms are complexity effective and worth implementing. In this paper, we perform a complexity analysis of a cache controller designed by extending an MSI controller to support thread-level memory speculation. We model and estimate the delay of the control logic on critical paths and the area overhead to hold additional control bits in the cache directory. Our analysis shows that for many protocol operations, the directory access time occupies more than half of the total delay. The total overhead is however smaller than the delay for accessing the cache tags. Since the protocol operations can be performed in parallel with the tag access, the resulting critical path latency is only slightly increased.

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.

Design patterns for pseudo-3D photo collage
"Pseudo-3D Photo Collage", one of new wed3D techniques, is based on multiple photographs and Spatial-Hyperlinks. A user can design various patterns of HyperPhoto-Networks, for example, linear, loop, tree, grid, rhizome and so on. It is similar to design a website based on HyperText-Networks. We propose several design patterns and those applications to create highly-designed virtual sequences.

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.

A New Algorithm for Analysis of Within-Host HIV-1 Evolution
A new algorithm for inferring the evolution of within-host viral sequences is presented. A sequential-linking approach is developed so that a longitudinal phylogenetic tree can be reconstructed from sequential molecular data that are obtained at different time points from the same host. The algorithm employs a codon-based model, which uses a Markov process to describe substitutions between codons, to calculate nonsynonymous and synonymous substitution rates and to distinguish positive selection and neutral evolution. The algorithm is applied to a data set of the V3 region of the HIV-1 envelope genes sequenced at different years after the infection of a single patient. The results suggest that this algorithm may provide a more realistic description of viral evolution than traditional evolutionary models, because it accounts for both neutral and adaptive evolution, and reconstructs a longitudinal phylogenetic tree that describes the dynamic process of viral evolution.

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.
