A semi-automatic alignment method for math educational standards using the MP (materialization pattern) model

Educational standards alignment, which matches similar or equivalent concepts of educational standards, is a necessary task for educational resource discovery and retrieval. Automated or semi-automated alignment systems for educational standards have been recently available. However, existing systems frequently result in inconsistency in interpreting a correct alignment or give only a “yes” or no” Boolean decision for alignment. In this research, we present a novel semi-automatic alignment method for math educational standards that goes beyond simple Boolean decision making. Our approach gives seven different degrees of alignments: Strongly Fully-aligned (SFA), Weakly Fully-aligned (WFA), Partially-aligned*** (PA***), Partially-aligned** (PA**), Partially-aligned* (PA*), Poorly-aligned (PR), and Not-aligned (NA). We aim to clarify and extend the notion of alignment for math educational standards, and to broaden categories of resource discovery and retrieval. First, we propose the MP (Materialization Pattern) model for representing the semantics of math educational standards for the purpose of aligning these standards. The MP model captures the semantics of English sentences used in math educational standards based on the Reed-Kellogg sentence diagram. We develop a semi-automatic tool, MPViz, for creating the MP model using the UML notation. The MPViz also converts an MP diagram to two graphs—a verb-phrase graph and a noun-phrase graph—which facilitate the process of automatic alignments. We align math educational standard statements using graph matching with the Bloomtaxonomy, the WordNet, and taxonomies of math concepts. We also develop a semiautomatic tool, MPComp, for aligning math educational standards. This dissertation describes a novel semi-automatic alignment method that utilizes the MP modeling and graph matching. Our experiments show that our alignment method provides the result that is comparable to human judgment. The contributions of our alignment method are as follows: 1) We propose the MP model that can explicitly model the semantics of English sentence structures used in math educational standards; 2) Using the MP model we develop a semi-automatic alignment method that produces seven different degrees of alignments, instead of simple Boolean decisions in existing alignment systems; 3) The multiple degrees of alignments empower education professionals by broadening categories of search or retrieval for educational resources.Ph.D., Information Science and Technology -- Drexel University, 201

Designing a Data Warehouse for Cyber Crimes

One of the greatest challenges facing modern society is the rising tide of cyber crimes. These crimes, since they rarely fit the model of conventional crimes, are difficult to investigate, hard to analyze, and difficult to prosecute. Collecting data in a unified framework is a mandatory step that will assist the investigator in sorting through the mountains of data. In this paper, we explore designing a dimensional model for a data warehouse that can be used in analyzing cyber crime data. We also present some interesting queries and the types of cyber crime analyses that can be performed based on the data warehouse. We discuss several ways of utilizing the data warehouse using OLAP and data mining technologies. We finally discuss legal issues and data population issues for the data warehouse

Developing and Analyzing the MP (Materialization Pattern) Model for Math Educational Standards

Educational standard s alignment , which matches similar or equivalent concepts of educational standards, is a necessary task for educational resource retrieval. In order to automate the alignment task, it is important to model the semantics of educational standards statements that are imperative mood sentences . In this paper, we present the MP (Materialization Pattern) model for representing the semantics of math educational standards for the purpose of aligning math educational standard s. This article first classifies math educational standard s statements into 16 types and then converts them to the MP model. The MP model is based on the Reed-Kellogg sentence diagrams, and created as MP diagrams using the UML notation. The MP model explicitly represents the semantics of the sentences by capturing math concepts and the cognitive process of the math concepts from math educational standards statements . The MP model is developed for automating the alignment of math educational standards

A survey on ontology mapping

Ontology is increasingly seen as a key factor for enabling interoperability across heterogeneous systems and semantic web applications. Ontology mapping is required for combining distributed and heterogeneous ontologies. Developing such ontology mapping has been a core issue of recent ontology research. This paper presents ontology mapping categories, describes the characteristics of each category, compares these characteristics, and surveys tools, systems, and related work based on each category of ontology mapping. We believe this paper provides readers with a comprehensive understanding of ontology mapping and points to various research topics about the specific roles of ontology mapping
