Semantical-coordinate Terms Detection from Hierarchical Knowledge Using Web Snippets

AbstractIn this paper, we describe a method to detect semantical-coordinate terms. We often use semantical-coordinate terms as objects of comparative validation and examples for the given term, and then linguistic expressions and knowledge processing are enriched. Semantical-coordinate terms should be hyponyms of a same hypernym, and their usage and concepts should be similar. However hierarchical knowledge is useful to view concepts, hierarchically coordinate terms are sometimes inappropriate as semantical-coordinate terms for our suppositions, because some of them might have multiple hypernyms and general perceptions of the terms are not taken in the consideration. On the other hand, using only Web context to detect semantical-coordinate terms, concepts of the terms are not taken in the consideration while public perceptions and their usages might be incorporated. Therefore we propose hybrid method using both hierarchical knowledge and Web snippets. We conducted bench scale tests to detect semantical-coordinate terms of some terms and discuss about the results in this paper. Through the tests and discussions, we confirmed that the semantical-coordinate terms detected by our proposed method were not only hierarchically but also semantically and intuitively appropriate

Alternative-ingredient Recommendation Based on Co-occurrence Relation on Recipe Database

AbstractThis paper proposes a recommendation method of alternative-ingredients based on co-occurrence relation on recipe database. Currently, dishes are often cooked with reference to recipes on Website. Convenience to access so many and varied recipes encourages beginners to cook. Recipe on Website list ingredients used for a dish. However, for some reason, some of the listed ingredients cannot be used for the cooking; this paper defines such ingredient as “exchange-ingredient.” To cook a dish, it should alternate exchange-ingredient and another one (i.e., alternative-ingredient). This paper proposes two algorithms to recommend alternative-ingredient. Through the cooking and tasting experiments, it was confirmed that the each of the proposed methods were effective for each intended purpose

Association of Pain History and Current Pain With Sagittal Spinal Alignment and Muscle Stiffness and Muscle Mass of the Back Muscles in Middle-aged and Elderly Women

[Study Design] A cross-sectional study. [Objective] To investigate the association of low back pain history (LBPH) and LBP with sagittal spinal alignment, stiffness assessed using ultrasonic shear wave elastography, and mass of the back muscle in community-dwelling middle-aged and elderly women. [Summary of Background Data] The association of LBPH and LBP with sagittal spinal alignment, stiffness, and mass of the back muscles remains unclear in middle-aged and elderly women. [Participants and Methods] The study comprised 19 asymptomatic middle-aged and elderly women [control (CTR) group], 16 middle-aged and elderly women with LBPH (LBPH group), and 23 middle-aged and elderly women with LBP (LBP group). Sagittal spinal alignment in the standing and prone positions (kyphosis angle in the thoracic spine, lordosis angle in the lumbar spine, and anterior inclination angle in the sacrum) was measured using a Spinal Mouse. The stiffness of the back muscles (lumbar erector spinae and multifidus) in the prone position was measured using ultrasonic shear wave elastography. The mass of the back muscles (thoracic and lumbar erector spinae, lumbar multifidus, and quadratus lumborum) was also measured. [Results] Multiple logistic regression analysis with a forward selection method showed that the stiffness of the lumbar multifidus muscle was a significant and independent factor of LBPH. The stiffness of the lumbar multifidus muscle was significantly higher in the LBPH group than in the CTR group. Multiple logistic regression analysis also indicated that lumbar lordosis angle in the standing position was a significant and independent factor of LBP. The lumbar lordosis angle was significantly smaller in the LBP group than in the CTR group. [Conclusions] Our results suggest that LBPH is associated with increased stiffness of the lumbar multifidus muscle in the prone position, and that LBP is associated with the decreased lumbar lordosis in the standing position in community-dwelling middle-aged and elderly women

Answering questions of Information Access Dialogue (IAD) task using ellipsis handling of follow-up questions

In this paper, we propose ellipsis handling method for follow-up questions in Information Access Dialogue (IAD) task of NTCIR QAC3. In this method, our system classifies ellipsis patterns of question sentences into three types and recognizes elliptical elements using ellipsis handling algorithm for each type. In the evaluation using Formal Run and Reference Run data, there were several cases which our algorithm could not handle ellipsis correctly. According to the analysis of evaluation results, the main reason of low performance was lack of word information for recognition of referential elements. If our system can recognize word meanings correctly, some errors will not occur and ellipsis handling works well.
