We also need to move up in terms of the semantic level we deal with in this information 我們也需要向上在我們在數(shù)據(jù)方面處理的與語意有關(guān)的水平術(shù)語中移動。
Audio data can be static or dynamic, and the audio retrieval can be at expression level or semantic level 音頻數(shù)據(jù)的存在形式有靜態(tài)與動態(tài)之分,在檢索層次上也有表示級檢索和語義級檢索之分。
Even before you get around to processing such annotations at the semantic level, you can use them in documentation tasks 即使在準(zhǔn)備從語義層面上處理這類注釋之前,也可以在文檔任務(wù)中加以利用。
But it is still interesting to consider whether top-down or bottom-up approaches will be most crucial in establishing true interoperability at the semantic level 不過我們也可以考慮一下自頂向下和自底向上兩種方法哪一種對于在語義層建立真正的透明性來說更加關(guān)鍵。
As the semantic web put fonvard, it becomes possible that the net can be presented with semantic, and the semantic web provides a way to search information on semantic level 隨著語義互聯(lián)網(wǎng)的提出,為計(jì)算機(jī)能較好的表述網(wǎng)絡(luò)信息的語義和為語義層上更為精確的訪問和搜索提供可能。
In this paper, a lot research work has been done around three points : how to abstract and index low-level feature of images, how to retrieval images in semantic level, and how to fill the semantic gap by relevant feedback technique 前者研究的是根據(jù)自動獲取的圖像低層特征,從圖像數(shù)據(jù)庫中檢索出相關(guān)圖像;而后者研究的是如何從多種渠道獲取圖像語義信息,并根據(jù)語義檢索相關(guān)圖像。
This paper solves the two problems . firstly, this paper adopts ontology which can describe knowledge in semantic level as concepts modeling tool . the tool solves the problem of abundance of commodity information organized disorderedly and forms sharing concepts model 首先,本文采用ontology作為一種能在知識語義層次上描述信息的概念建模工具,既解決了大量商品信息組織混亂的問題,又形成共享概念模型。
This paper discusses the theory and a method for spatial metadata interoperability based on the metadata interoperability of spatial information semantic level, and presents the technical framework of spatial information metadata interoperability 摘要從空間信息語義層中的元數(shù)據(jù)互操作角度出發(fā),討論適用于空間信息元數(shù)據(jù)互操作的理論和方法,并提出基于擴(kuò)展的元數(shù)據(jù)互操作協(xié)議的空間信息元數(shù)據(jù)互操作理論應(yīng)用技術(shù)框架。
Xml, as the seed technology within the progress of the web, is the universal applicable declarative syntax in the future web, and rdf providing a data model for resource description and a set of primitives at semantic level is the technical foundation of semantic web web已經(jīng)到了向語義化發(fā)展的一個轉(zhuǎn)折點(diǎn):xml提供了通用的表示語法,是web向語義化方向發(fā)展的種子技術(shù);rdf提供了語義上描述知識的數(shù)據(jù)模型和一組基本的描述原語,是語義化web在語義上的技術(shù)基礎(chǔ)。
This feature perfectly combine the frequency in acoustics level and the temperament in music semantic level, we use the cosine distance of this feature to represent the similarity of two music clips, then we design a group of algorithms that is inspired from the thought of edit distance and dynamic programming . they segment the feature vectors into groups at first, then through group similarity match, group recurrent detect, merge recurrent group and structure label joined algorithms to complete the music structure label task . because this is a really new field of research and no good method of evaluation had been finding, we propose a new evaluation method and the results of the experiments show that it is a good method 然后設(shè)計(jì)了一組源于編輯距離和動態(tài)規(guī)劃思想的音樂結(jié)構(gòu)分析算法,首先將特征向量分組,然后經(jīng)過組相似匹配、組重現(xiàn)檢測、重現(xiàn)組歸并和自動標(biāo)注四個前后銜接的環(huán)節(jié)實(shí)現(xiàn)了音樂結(jié)構(gòu)的自動標(biāo)注,較好地實(shí)現(xiàn)了將音頻形式的音樂自動標(biāo)注為表示音樂結(jié)構(gòu)的三元組列表形式,由于這是一個新的領(lǐng)域,目前還沒有比較好的量化評價方法,本文提出一種新的評價方法,并用它來評價結(jié)構(gòu)分析的結(jié)果,取得了較好的效果。
