Exploring Graphs with Elixir: Connect Data with Native Graph Libraries and Graph Databases

為了解決Cypher的問題，作者Hammond, Tony 這樣論述：

Data is everywhere - it’s just not very well connected, which makes it super hard to relate dataset to dataset. Using graphs as the underlying glue, you can readily join data together and create navigation paths across diverse sets of data. Add Elixir, with its awesome power of concurrency, and y

ou’ll soon be mastering data networks. Learn how different graph models can be accessed and used from within Elixir and how you can build a robust semantics overlay on top of graph data structures. We’ll start from the basics and examine the main graph paradigms. Get ready to embrace the world of co

nnected data!Graphs provide an intuitive and highly flexible means for organizing and querying huge amounts of loosely coupled data items. These data networks, or graphs in math speak, are typically stored and queried using graph databases. Elixir, with its noted support for fault tolerance and conc

urrency, stands out as a language eminently suited to processing sparsely connected and distributed datasets.Using Elixir and graph-aware packages in the Elixir ecosystem, you’ll easily be able to fit your data to graphs and networks, and gain new information insights. Build a testbed app for compar

ing native graph data with external graph databases. Develop a set of applications under a single umbrella app to drill down into graph structures. Build graph models in Elixir, and query graph databases of various stripes - using Cypher and Gremlin with property graphs and SPARQL with RDF graphs. T

ransform data from one graph modeling regime to another. Understand why property graphs are especially good at graph traversal problems, while RDF graphs shine at integrating different semantic models and can scale up to web proportions.Harness the outstanding power of concurrent processing in Elixi

r to work with distributed graph datasets and manage data at scale.What You Need: To follow along with the book, you should have Elixir 1.10+ installed. The book will guide you through setting up an umbrella application for a graph testbed using a variety of graph databases for which Java SDK 8+ is

generally required. Instructions for installing the graph databases are given in an appendix.

不同錯誤提示方式對程式學習之研究

為了解決Cypher的問題，作者黃建嘉 這樣論述：

許多學生常會因為無法撰寫出正確的程式而造成程式的錯誤，因此，除錯被認為是一項重要的程式能力。研究指出，透過「提示」能有效激發學生的高階思維能力，讓學生在回應不同內容和任務時，採用合適的批判性思維技能。不同學習成就的學生，在學習程式的成敗原因上，多歸因於學習策略的選擇不同；缺乏學習策略與實踐是程式設計成敗與否的關鍵。本研究以程式設計學習為基礎，建置一圖形化程式設計系統，具備友善的錯誤提示功能，包含「關鍵提式」和「逐步提式」。實驗期程為5週，並採用準實驗研究法，以臺北市某國小的六年級學生，共75人為參與對象，實驗分為三組，分別為關鍵提示組、逐步提示組與教師錯誤說明組，經過教學實施後進行單因子共變

數分析，以探討不同提示模式對於學生程式學習之影響。本研究的研究發現：一、逐步提示組在程式設計上的表現優於關鍵提示組與教師錯誤說明組。二、逐步提示組在程式設計自我效能的表現優於關鍵提示組與教師錯誤說明組。三、逐步提示組在問題解決能力的表現優於關鍵提示組與教師錯誤說明組。研究結果顯示逐步提示組的表現都優於其他兩組，就實驗對象的觀察上，因實驗對象多為學習成就較低及弱勢之學生，因此在學習上需要透過逐步的錯誤提示思考來進行引導，藉此幫助他們更能理解問題並從中思考問題的解決方法。

Dark Matter in Breaking Cyphers: The Life of Africanist Aesthetics in Global Hip Hop

為了解決Cypher的問題，作者Johnson, Imani Kai 這樣論述：

The dance circle (called the cypher) is a common signifier of breaking culture, known more for its spectacular moves than as a ritual practice with foundations in Africanist aesthetics. Yet those foundations--evident in expressive qualities like call and response, the aural kinesthetic, the imper

ative to be original, and more--are essential to cyphering’s enduring presence on the global stage. What can cyphers activate beyond the spectacle? What lessons do cyphers offer about moving through and navigating the social world? And what possibilities for the future do they animate? With an inter

disciplinary reach and a riff on physics, author Imani Kai Johnson centers the voices of practitioners in a study of breaking events in cities across the US, Canada, and parts of Europe. Dark Matter in Breaking Cyphers: the Life of Africanist Aesthetics in Global Hip Hop draws on over a decade of re

search and provides a detailed look into the vitality of Africanist aesthetics and the epistemological possibilities of the ritual circle.

應用於原生圖形資料庫之並行控制協定

為了解決Cypher的問題，作者王奕中 這樣論述：

至今對於資料分析的需求漸增，而有越來越多企業採用圖形資料庫來運算資料，像是Twitter、Manning Publications等的公司，然而，作為企業級儲存資料庫，資料的正確性對於使用者個人隱私問題將會是個議題，主要是因為競爭危害問題(race condition)。因此，本研究提出一個以鎖為基礎的樹狀協定，應用在原生圖形資料庫中，原生圖形資料庫代表資料庫的設計從頭到尾是以圖形演算法為主，同時也是採用標籤屬性圖為資料模型的資料庫。 原生圖形資料庫像是開源的Neo4j，只達到保證讀取的獨立性等級，象徵的是，交易的執行當中仍可能會有異常行為出現，因此本研究採用在關聯式資料庫中發

展成熟的B樹鎖協定，移植到圖形資料庫當中作為並行控制協定的結構，將透過建構一棵平衡B+樹做為儲存媒介，因為它的新增、讀取、更新、刪除都能在時間複雜度Big-O(logN)中，樹結構分為內部節點與葉節點，內部節點作為資料索引的路由，葉節點為實際圖形資料的儲存節點；B樹鎖協定利用成對鎖機制阻擋其他交易超越先進行的交易，如此一來不會產生死結，更重要的是能夠達到可序列化等級。
