AnHitz is a project promoted by the Basque Government to develop language technologies for the Basque language. The participants in AnHitz are research groups with very different backgrounds: text processing, speech processing and multimedia. The project aims to further develop existing language, speech and visual technologies for Basque: up to now its fruit is a set of 7 different language resources, 9 NLP tools, and 5 applications.. But also, in the last year of this project we are integrating, for the first time, such resources and tools (both existing and generated in the project) into a content management application for Basque with a natural language communication interface. This application consists of a Question Answering and a Cross Lingual Information Retrieval system on the area of Science and Technology. The interaction between the system and the user will be in Basque (the results of the CLIR module that are not in Basque will be translated through Machine Translation) using Speech Synthesis, Automatic Speech Recognition and a Visual Interface. The various resources, technologies and tools that we are developing are already in a very advanced stage, and the implementation of the content management application to integrate them all is in work and is due to be completed by October 2008.

Wavefront reconstruction such as holography is an ideal method for three-dimensional display. According to the development of spatial light modulator, quality of reconstructed three-dimensional object is improved. However, there are many problems to be solved for commercially available product. In wide viewing zone, it is required to use high power light source. But the limited power to avoid the damage in spatial light modulator should be illuminated. In this paper, we propose the coherent amplification of three-dimensional object by a polymer dye after the modulation of spatial light modulator. In the experiment, we use a polymer with Rohdamine 6G as a coherent amplifier. Two character images are reconstructed experimentally at different propagation distances. The amplification is achieved at 15 times with a thickness of 8 mm in end pump configuration. We also present numerical evaluation of reconstructed beam in different displayed distributions on spatial light modulator.

To improve the amount of transmitted information via a sensory substitution system, we examined tactile perception characteristics of the index finger while presenting broadband vibrotactile stimuli. A pin-matrix tactile display composed of 12 piezoelectric bimorph actuators was used to elicit tactile sensations. The piezoelectric bimorph actuator of the display possesses flat frequency characteristics in the tactilely perceivable bandwidth of vibratory sensations. The actuator can therefore generate skin displacement patterns onto a fingertip surface in accordance with the waveform of the input voltage to the actuator. An open question of tactile sensations induced by multiple frequencies and waveforms was performed using the tactile display. A psychological scaling test of tactile sensations was conducted with the aim of transmitting voice quality information by tactile sensations. Most subjects perceived common changes of tactile sensations. This provides a guideline for the voice quality transmit function of tactile aids for the hearing impaired and other communication devices.

It is an important issue to understand the mechanism of personal opinion expression and consensus building in communities. We implemented an interactive application called ldquofuture chroniclerdquo for monitoring personal opinion expression and consensus building in communities. Future chronicle produces the field of personal opinion expression from multiple users, and users can share their thoughts with each other on this field. Moreover, we can observe the growth of communities through this application. In this paper, we report our experiments using future chronicle.

V N and N V sequence in Chinese may be a noun phrase. This characteristic makes NP chunking in Chinese particularly difficult. We present a method to tackle this problem by combining Chinese Sinica Treebank data with unlabelled data to train a better model based on SVM. Experiments with open test data show that our proposed semi-supervised approach can achieve the accuracy of 78.79% in f-measure, enhancing the f-measure by 8.79% over the supervised approach.

This paper presents a method for the creation of dynamic cross-domain links for interconnection of heterogeneous knowledge bases. The proposed method represents various relationships in heterogeneous fields and navigates to related contents in these heterogeneous fields. Most information resources are connected by static links that do not describe the significance of the connections. Recently, it has been important for a lot of users to employ search engines not only for retrieving Web pages but also for understanding or learning semantic concepts. However, in the current Web environment, it remains difficult for a user to understand the relationships among arbitrary concept. The proposed method dynamically creates links between heterogeneous fields depending on the user context. The method obtains various related information resources between heterogeneous fields while understanding various relationships among arbitrary concepts. Our approach has functions for the reconfiguration of Web resources and legacy knowledge bases by dynamic links creation.

In the driving circumstance, the driver¿s condition is directly connected with the car accident. Therefore, there are many researches to decrease the car accidents by keeping the driver¿s state in a good condition. While many of these researches are focused on the driver¿s face, our approach is focused on the driver¿s head movement. By collecting the driver¿s head position and extracting the feature points, the proposed system calculates the driver¿s physical state: Normal driving or Drowsy driving. The experimental results showed 78% of success rate to find the drowsy driving in the real driving situations.

This research investigated the effect of using a three-dimensional online chat environment on community development for cancer patients¿ mental health. In the support group, from two to five patients and one facilitator chatted in virtual space for a one and half hour session every week for three years using avatars with emotional expressions. The messages in the support group were analyzed by text mining tool. The results showed that the frequency of positive emotion words increased, on the other hand, the negative words decreased after one year. The percentage of participants¿ messages gradually increased with the sessions. The informational support in messages for improving their QOL (quality of life) increased during the three years. These data showed that the virtual support group promotes patients¿ positive emotions, QOL, and autonomy of the self-help group.

Text generation systems, such as pun generators, depend on manually created templates which require a lot of effort to build. This paper presents T-Peg, a system that utilizes semantic and phonetic knowledge sources to automatically capture the wordplay patterns of human-made jokes from training examples. The knowledge learned are stored as templates which, combined with a keyword input from the user, can then be used to generate punning riddles. Manual evaluation by a linguist on the completeness of the learned templates gave the system a score of 4.0 out of 5. User feedback gave the computer-generated puns an average score of 2.13 out of 5, as compared to their human-made counterparts which received an average score of 2.70, demonstrating that computers can be trained to be as humorous as humans.
