After analyzing the principle of keywords and concept retrieval , a new vector space model named sc - vsm based on the semantic concept retrieval was proposed 摘要對(duì)關(guān)鍵詞和概念檢索的原理進(jìn)行分析后,提出了一種基于語(yǔ)義概念檢索的向量空間模型以及該模型與關(guān)鍵詞檢索結(jié)合的檢索方法。
The next two installments of xml matters will touch on issues like merging grammars , infoset augmentation or lack thereof , fudging cardinality constraints , and a few other semantic concepts Xml問(wèn)題的后兩篇專欄文章將粗略地討論象合并語(yǔ)法、增加信息集(或缺少信息集) 、插入基數(shù)約束以及其它數(shù)個(gè)語(yǔ)義概念這樣的問(wèn)題。
Any general purpose alternative syntax for xml is still going to bump up against the limits of that generalness : there are few general semantic concepts , so the opportunity for collapsing them into abbreviated syntax is limited 任何通用的xml替代語(yǔ)法仍然在嘗試沖破通用性的限制:只有少量的通用語(yǔ)義概念,因此限制了把它們壓縮成簡(jiǎn)潔語(yǔ)法的機(jī)會(huì)。
“ semantic gap ” is the gulf between the low - level image visual feature and high - level concepts , the images can be different of semantic concept while having similar visual feature , and they can also be different of visual feature while having the same concept “語(yǔ)義鴻溝”是指圖像的低級(jí)視覺(jué)特征和高級(jí)語(yǔ)義特征之間的差距,由計(jì)算機(jī)計(jì)算出來(lái)的低級(jí)特征的相關(guān)性很難說(shuō)明圖像在語(yǔ)義層上的相似性,語(yǔ)義層上的相似性也無(wú)法證明低級(jí)特征的相關(guān)性。
