The linear text representation is suboptimal for audio search, where accuracy can be significantly improved if the search includes alternate recognition candidates, commonly represented as word lattices.This paper proposes a method for indexing word lattices that is suitable for large-scale web-search engines, requiring only limited code changes.The proposed method, called Time-based Merging for Indexing (TMI), first converts the word lattice to a posterior-probability representation and then merges word hypotheses with similar time boundaries to reduce the index size. Four alternative approximations are presented, which differ in index size and the strictness of the phrase-matching constraints.Results are presented for three types of typical web audio content, podcasts, video clips, and online lectures, for phrase spotting and relevance ranking. Using TMI indexes that are only five times larger than corresponding linear-text indexes, phrase spotting was improved over searching top-1 transcripts by 25-35%, and relevance ranking by 14%, at only a small loss compared to unindexed lattice search.","PeriodicalId":62986,"journal":{"name":"山西省考古学会论文集","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2006-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86128911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CAD/CAM equipment is being rapidly installed in schools of architecture without much thought given to its effect on the tradition of tectonics. To investigate these effects, this paper includes discussions of the tradition of architectural tectonics and of more recent works that illustrate the possibilities of digital tectonics. This discussion is followed by a brief survey of some of the research in the area of analog/digital pedagogy. Additionally, two experiments were conducted in an academic course setting that explored analog, digital, and hybrid approaches to the creation of architectural artifacts. The physical and virtual artifacts from the two experiments were analyzed and commonalities and differences were discerned. The research project reported in this paper further clarifies the notion of digital tectonics as the poetics of digitally constructed assemblages, and points to possible pitfalls of using CAD/ CAM equipment that disregard the materiality of components and their interconnectedness.

Strength testing indicates this directly on a yes or no basis, whereas computations are able to compare the level of stress with the strength of the material. Understanding the interplay between load, form, and material which structural mechanics is able to provide can be of considerable and far-reaching importance, both at an early conceptual design stage and while developing parts and details. The aim of this paper is to show how structural mechanics (in particular, static eigenvalue analysis) can be used to create work methods that provide a common language between the designer and the engineer during the design process. A case study is presented in which the Finite Element Method (FEM) was used to perform static eigenvalue analyses aimed at facilitating a collaborative furniture design process in the creation of a shell-shaped chair. Analysis of this sort was chosen because it can be used in a sketch-like manner. The designer found it easy to incorporate the results of the analysis into his own sketching work. It also enabled him to see how different design changes affected the overall structural behaviour of the chair without him having to create a full-scale prototype for physical testing.","PeriodicalId":62986,"journal":{"name":"山西省考古学会论文集","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73386381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
