【摘要】：隨著在線評(píng)論信息數(shù)量的快速增長(zhǎng)與應(yīng)用的不斷擴(kuò)展,評(píng)論挖掘研究得到學(xué)術(shù)界的持續(xù)關(guān)注。當(dāng)前的評(píng)論挖掘任務(wù)對(duì)屬性的全面性、細(xì)粒度等要求越來(lái)越高,而多數(shù)現(xiàn)有研究方法主要關(guān)注評(píng)價(jià)對(duì)象主要屬性的抽取。盡可能地發(fā)現(xiàn)評(píng)價(jià)對(duì)象的全部用戶關(guān)注屬性、并以細(xì)粒度方式表述屬性,是一項(xiàng)有意義的工作。本文提出一種細(xì)粒度屬性抽取方法,旨在全面、快速地抽取產(chǎn)品屬性。本文首先利用高頻名詞構(gòu)建候選屬性詞;然后通過(guò)深度學(xué)習(xí)構(gòu)建候選屬性詞向量,在此基礎(chǔ)上完成候選屬性的聚類,得到聚類后的候選屬性詞集;最后對(duì)候選屬性詞集進(jìn)行噪音過(guò)濾,得到細(xì)粒度產(chǎn)品屬性集。在飲食、手機(jī)、圖書(shū)等三個(gè)領(lǐng)域評(píng)論語(yǔ)料上的實(shí)驗(yàn)結(jié)果表明,相對(duì)于基于種子詞的方法、基于結(jié)合人工的LDA方法及基于情感詞的方法,本文方法能夠更加全面地發(fā)現(xiàn)評(píng)價(jià)對(duì)象屬性,并且能夠給出細(xì)粒度的屬性。
[Abstract]:With the rapid growth of online review information and the continuous expansion of applications, the research of comment mining has been continuously concerned by the academic community. The current task of comment mining requires more and more comprehensive attributes, fine-grained and so on. Most of the existing research methods mainly focus on the extraction of the main attributes of the evaluation object. As far as possible, we can find all the user concerned attributes of the evaluation object, and express the attributes in a fine-grained manner. In this paper, a fine-grained attribute extraction method is proposed to extract product attributes comprehensively and quickly. Firstly, candidate attribute words are constructed by using high-frequency nouns. Then, the candidate attribute word vector is constructed by in-depth learning, and the candidate attribute word set is obtained by clustering the candidate attribute. Finally, the candidate attribute word set is filtered by noise, and the fine-grained product attribute set is obtained. The experimental results in the review corpus of diet, mobile phone and book show that compared with the method based on seed words. Based on the combination of artificial LDA method and affective word based method, this method can find evaluation object attributes more comprehensively, and can give fine grained attributes.
