as a resu1t, the text is represented as a vector in the csvs after removing a11 unclassfiab1e sememes . the simi1ar texts form a c1uster in the csvs 在訓(xùn)練集中的文本均表示成向量空間的文本之后,訓(xùn)練集中相似的向量在向量空間中會形成文本聚類。

all these are the foundation of the latter control system design and the software developed . a hybrid control scheme of csvs method and the technology of active vibration suppression using piezoelectric materials is proposed for the vibration control of a flexible spacecraft actuated by on-off thrusters 針對撓性航天器的動力學(xué)模型存在著模型不確定性因素以及外部擾動的作用的魯棒控制問題,提出了將變結(jié)構(gòu)輸出反饋控制應(yīng)用于撓性航天器的大角度機(jī)動控制中。
thi s paper proposes a new automatic natura1 1anguage text categorization modu1e based on concept . thi s modu1e takes howwenet as the main source of knowledge, the concepts of words as the bas; is of text categorization . the concepts of words are reduced to sememes and the tc is performed in the classfiab1e sememe vector space ( csvs ) 本文提出了一個(gè)基于概念的自然語言文本自動分類模型,該模型以《知網(wǎng)》為主要的概念知識源,以詞所表示的概念為分類基礎(chǔ),把概念繼續(xù)分解至義原,并在可分義原組成的向量空間進(jìn)行文本分類。
