基於統計準則式方法強化出版物參考元數據提取方法之研究
為了解決CRF250 的問題，作者楊庭豪 這樣論述：
出版物字串是描述資源資訊以讓其他研究者可以搜尋到該資源的一種特殊格式字串，通常用於論文最後引用資料描述以及研究者個人的著作資料整理。我們延續過去的研究基礎，提出結合統計技術與知識規則的方法，透過自動化的準則生成演算法與匹配演算法將出版物字串資料轉換為結構化資訊。出版物參考元數據提取作為學術資料結構化的基本任務，除了用於文獻檢索的精確資訊萃取以外，對於研究學術社群活動網路關係也有助益。然而文獻引用格式的變化性大，且文獻格式也以驚人速度增加，這對於出版物參考元數據提取造成障礙。在這一篇論文中，我們將針對此議題作探討，尋求方法來提升參考元數據提取的效果。此篇論文將研究方向集中在兩個議題上：(1)
整合統計技巧與知識本體之系統設計：我們建構了一套知識表達與應用的環境。該環境包含了知識管理環境與整合式方法核心模型，整合式方法核心模型結合了階層架構式的知識本體與統計方法。在簡化了標記工作的同時仍可以保有資訊提取效能。結合知識的系統架構也使得專家能夠分析各階段的錯誤,並針對關鍵處快速改善系統。我們以此環境開發了出版物參考元數據提取模型。(2) 以統計準則式方法(Statistical Principle-Based Approach, SPBA)強化出版物參考元數據提取： 過去實驗室發展了幾個系統來處理出版物參考元數據提取的任務，在發展過程中我們針對準則產生方式改進並嘗試用於不同任務，最後發展
出了SPBA。SPBA方法有三個步驟，第一步為建立知識本體(Ontology)，並用這些知識對文本進行語意標注(Semantic Labeling)。第二步將前一步驟生成的樣板(Pattern)透過準則生成演算法(Principle Generation Algorithm)將樣板們整合成具有代表性的準則(Principles)。最後用準則批配演算法(Principle Matching)提供彈性比對機制以處理多變的引用格式在本論文中，我們以出版物參考元數據提取任務的公開資料集與專家編輯過的雜訊資料集來驗證SPBA方法的可用性，實驗測試了四個期刊論文引用字串資料集跟一個會議論文引用字串資料集。
我們也比較了當前技術的CRF與Bi-LSTM-CRF方法，SPBA方法在元數據提取任務的效能上在各資料集都獲得了改進。在使用較少訓練資料的實驗中也驗證了SPBA的強健性。大多數的出版物參考元數據提取研究少有提出整合機器學習與知識規則的方法，SPBA可填補此空缺。本研究的貢獻可歸納為下列幾點：第一是結合精簡標記與批配，可以減輕標記工作的負擔。第二是讓從資料中生成準則，可以減輕專家撰寫準則的負擔。第三是我們分享了新的出版物參考元數據提取任務資料集，讓後續研究可以有新的發展材料。SPBA作為一個結合知識本體與統計方法的的技術，能夠產生有可讀性的準則，也能夠讓從各步驟中理解出錯誤的原因，這種具可解釋性
的特性將有助於拓展到未來其它需要細緻處理語意的資訊萃取任務。

探討番茄的CEP2/3胜肽參與叢枝菌根菌促進側根形成之作用
為了解決CRF250 的問題，作者魏禕嫺 這樣論述：
植物的側根經常會在與叢枝菌根菌( arbuscular mycorrhizal fungi)共生的時候增加。在我們過去的研究中已經發現，菌根菌共生會使番茄中的C-terminally encoded peptides (CEPs)，SlCEP2，表現量下降。外源施用於根部的生長素會減輕由脯胺酸上具有羥基化修飾的CEP2 (CEP2Hyp)胜肽處理所造成的側根形成缺陷，顯示CEP2會通過影響根部生長素相關的路徑來負調控側根形成。SlCEPR1 (CEP receptor 1)可能為CEP2的受體。同樣的，菌根菌共生可能會減輕CEP2胜肽的負面影響來增加側根形成。本研究的主旨在於更進一步探討CE
P2、CEPR1以及另一個也會被菌根菌共生負調節的CEP3，在菌根菌共生促進的側根生長中的作用。本研究發現CEP2的表現會可能受到由菌根菌所提供的氮源影響。成熟CEP2胜肽表現在細胞核、細胞質與細胞膜，並且CEP2胜肽可能並不會被運輸到植物的地上部。菌根菌共生與CEP2Hyp胜肽在側根原基形成上具有相反的功能。在根部施用IAA可以減輕CEP2Hyp所造成的側根形成缺陷。相反的，在地上部施用NAA卻不能恢復因CEP2Hyp處理而下降的植物側根密度，表示CEP2Hyp胜肽主要影響是在側根發育扮演重要角色且是來自根部的生長素。與病毒誘導的CEP2基因靜默 (CEP2-VIGS) 植物相反，CEPR1
-VIGS植物的側根密度仍會被菌根菌共生誘導增加，顯示CEP2的基因表現量對菌根菌共生促進的側根形成可能更為重要。大量表現CEP3會抑制菌根菌增加側根形成的能力，雖然其確切機制仍然未知。在我們的系統中，CEP2、CEPR1和CEP3對於菌根菌的生長發育非常微弱或無明顯影響。這些結果有助於了解菌根菌共生是如何通過調節CEP胜肽來增進番茄側根形成。
