<p>Research of protein-protein interactions produce vast quantities of data and there exists a large number of databases with data from this research. Many of these databases offers the data for download on the web in a number of different formats, many of them XML-based.</p><p>With the arrival of these XML-based formats, and especially the standardized formats such as PSI-MI, SBML and BioPAX, there is a need for searching in data represented in XML. We wanted to investigate the capabilities of XML query tools when it comes to searching in this data. Due to the large datasets we concentrated on native XML database systems that in addition to search in XML data also offers storage and indexing specially suited for XML documents.</p><p>A number of queries were tested on data exported from the databases IntAct and Reactome using the XQuery language. There were both simple and advanced queries performed. The simpler queries consisted of queries such as listing information on a specified protein or counting the number of reactions.</p><p>One central issue with protein-protein interactions is to find pathways, i.e. series of interconnected chemical reactions between proteins. This problem involve graph searches and since we suspected that the complex queries it required would be slow we also developed a C++ program using a graph toolkit.</p><p>The simpler queries were performed relatively fast. Pathway searches in the native XML databases took long time even for short searches while the C++ program achieved much faster pathway searches.</p>

Full textAbstract:
With the advent of XML as a standardized data representation model, the need has emerged to store, retrieve and update XML data. A new breed of databases called native XML databases have been designed from the ground up to perform such actions. McXML is an example of a native XML database. McXML was developed at McGill University and it specializes in updating XML. We have designed and developed a page based storage manager for McXML, which replaces the existing plain text manager. The new storage manager allows efficient persistence, retrieval and update of XML data using complex data structures. The new storage manager is more efficient than the original storage manager and sets the foundation for advanced features like concurrency control and buffer management in McXML. In particular, the new storage manager is effective in persisting updated data changes to disk. We prove the above assertions in performance benchmarks performed for this thesis.

<p>This thesis aims to find a graph structure for representing XML documents and to implement the former representation for storing such documents. The graph structure, in fact, is the complete representation for the XML documents; this is dued to the id/idref attribute which could be present inside the XML document tag.</p><p>Two different graph structures have been defined on this thesis, they are called most granular and customizable representations. The first one is the simplest way for representing XML documents, while the second one makes some improvements for optimizing inserting, deleting, and querying functions.</p><p>The implementation of the former graph structures is made over a new kind of database built specifically for storing semi-structured data, such database is called Neo. Neo database works only with three primitives: node, relationship, and property. Such data model represents a new solution compared to the traditional relational view.</p><p>The XML information manager implements two different API which work with the two former graph structure respectively. The first API works with the customizable representation, while the second one works with the customizable representation.</p><p>Some evaluations have been done over the second implemented API, and they showed that the implemented code is free of bugs and moreover that the customizable representation brings about some improvements on making queries over the stored data.</p>

Full textAbstract:
XML is being adopted as a common storage format in scientific data repositories, digital libraries, and on the World Wide Web. Accordingly, there is a need for content-oriented XML retrieval systems that can efficiently and effectively store, search and retrieve information from XML document collections. Unlike traditional information retrieval systems where whole documents are usually indexed and retrieved as information units, XML retrieval systems typically index and retrieve document components of varying granularity. To evaluate the effectiveness of such systems, test collections where relevance assessments are provided according to an XML-specific definition of relevance are necessary. Such test collections have been built during four rounds of the INitiative for the Evaluation of XML Retrieval (INEX). There are many different approaches to XML retrieval; most approaches either extend full-text information retrieval systems to handle XML retrieval, or use database technologies that incorporate existing XML standards to handle both XML presentation and retrieval. We present a hybrid approach to XML retrieval that combines text information retrieval features with XML-specific features found in a native XML database. Results from our experiments on the INEX 2003 and 2004 test collections demonstrate the usefulness of applying our hybrid approach to different XML retrieval tasks. A realistic definition of relevance is necessary for meaningful comparison of alternative XML retrieval approaches. The three relevance definitions used by INEX since 2002 comprise two relevance dimensions, each based on topical relevance. We perform an extensive analysis of the two INEX 2004 and 2005 relevance definitions, and show that assessors and users find them difficult to understand. We propose a new definition of relevance for XML retrieval, and demonstrate that a relevance scale based on this definition is useful for XML retrieval experiments. Finding the appropriate approach to evaluate XML retrieval effectiveness is the subject of ongoing debate within the XML information retrieval research community. We present an overview of the evaluation methodologies implemented in the current INEX metrics, which reveals that the metrics follow different assumptions and measure different XML retrieval behaviours. We propose a new evaluation metric for XML retrieval and conduct an extensive analysis of the retrieval performance of simulated runs to show what is measured. We compare the evaluation behaviour obtained with the new metric to the behaviours obtained with two of the official INEX 2005 metrics, and demonstrate that the new metric can be used to reliably evaluate XML retrieval effectiveness. To analyse the effectiveness of XML retrieval in different application scenarios, we use evaluation measures in our new metric to investigate the behaviour of XML retrieval approaches under the following two scenarios: the ad-hoc retrieval scenario, exploring the activities carried out as part of the INEX 2005 Ad-hoc track; and the multimedia retrieval scenario, exploring the activities carried out as part of the INEX 2005 Multimedia track. For both application scenarios we show that, although different values for retrieval parameters are needed to achieve the optimal performance, the desired textual or multimedia information can be effectively located using a combination of XML retrieval approaches.

Full textAbstract:
A video data model that allows efficient and effective representation and querying of spatio-temporal properties of objects has been previously developed. The data model is focused on the semantic content of video streams. Objects, events, activities performed by objects are the main interests of the model. The model supports fuzzy spatial queries including querying spatial relationships between objects and querying the trajectories of objects. In this thesis, this work is used as a basis for the development of an XML-based video database system. This system is aimed to be compliant with the MPEG-7 Multimedia Description Schemes in order to obey a universal standard. The system is implemented using a native XML database management system. Query entrance facilities are enhanced via integrating an NLP interface.

Full textAbstract:
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico<br>XML has become a widely used standard for data representation and exchange in applications.
The growing usage of XML creates a need for ecient storage and recovery
systems for XML data. Native XML DBs (NXDBs) are being developed to target this
demand. NXDBs implement many characteristics that are common to traditional DBs,
such as storage, indexing, query processing, transactions and replication.
Most existing solutions solve the replication issue through traditional techniques.
However, the
exibility of XML data imposes new challenges, so new replication techniques
ought to be developed. To improve the performance and availability of NXDBs,
this thesis proposes RepliX, a mechanism for XML data replication that takes into account
the main characteristics of this data type, making it possible to reduce the response
time in query processing and improving the fault-tolerance property of such systems.
Although there are several replication protocols, using the group communication
abstraction for communication and fault detection has proven to be a good solution,
since this abstraction provides ecient message exchanging techniques and conability
guarantees. RepliX uses this strategy, organizing the sites into an update group and a
read-only group in such a way that allows for the use of load balancing among the sites,
and makes the system less susceptible to faults, since there is no single point of failure in
each group.
In order to evaluate RepliX, a new replication layer was implemented on top of
an existing NXDB to introduce the characteristics of the proposed mechanism. Several
experiments using this layer were conducted, and their results conrm the mechanism's
eciency considering the dierent aspects of a replicated database, improving its performance
considerably, as well as its availability.<br>XML tem se tornado um padrÃo amplamente utilizado na representaÃÃo e troca de dados em aplicaÃÃes.

Approved for public release, distribution unlimited<br>Efforts to improve the military decision and action cycle have centered on automating the command and control process and improving interoperability among joint and coalition forces. However, information automation by itself can lead to increased operator overload when the way this information is stored and presented is not structured and consistently filtered. The majority of messaging systems store information in a document-centric free-text format that makes it difficult for command and control systems, relational databases, software agents and web portals to intelligently search the information. Consistent structure and semantic meaning is essential when integrating these capabilities. Military-grade implementations must also provide high performance. A widely accepted platform-independent technology standard for representing document-centric information is the Extensible Markup Language (XML). XML supports the structured representation of information in context through the use of metadata. By using an XML Schema generated from MIPâ s Land Command and Control Information Exchange Data Model (LC2IEDM), it is feasible to compare the syntactic strength of human-readable XML documents with the semantics of LC2IEDM as used within a relational database. The insert, update, retrieve and delete performance of a native-XML database is compared against that of a relational database management system (RDBMS) implementing the same command and control data model (LC2IEDM). Additionally, compression and parsing performance advantages of using various binary XML compression schemes is investigated. Experimental measurements and analytic comparisons are made to determine whether the performance of a native-XML database is a disadvantage to the use of XML. Finally, because of the globally significant potential of these interoperability improvements, a number of look-ahead items to future work are proposed including the use of.

Full textAbstract:
碩士<br>朝陽科技大學<br>資訊管理系碩士班<br>93<br>Since XML becomes a standard, applications based on it have grown rapidly. However the existing database systems, namely relational databases, provide inadequate facilities to manage the nested and ordered structures in XML documents. Therefore, there exist two important issues about the storage capacity for huge XML documents and the complexity mapping between the relational databases and XML repository. Though database compression can relief the storage capacity problem, the traditional compression method, like Huffman Coding, Arithmetic Encoding, Dictionary Coding, etc., cannot explore useful information.
For solving above the problems, we propose a compression method to compress the native XML database via data mining techniques. We apply the association mining technique to explore the frequent character data sets and frequent tag sets and then we use those frequent sets to establish the compression rules to compress the XML documents. In addition, XML documents may pile up over time. Therefore, we apply the dynamically mining techniques to maintain the compression rules. The approach contributes to the native XML database both in extracting hidden information and in lossless compression, respectively. The experimental results show that our compression method has powerful compression effectiveness.

Full textAbstract:
碩士<br>國立臺灣師範大學<br>資訊工程研究所<br>98<br>Nowadays, Internet has become the major information source for many people. When people need answer for certain problems, they often search Google, Wikipedia or other portals for the answers. Many websites, such as banks and government, use Frequently Asked Questions (FAQs) to provide a specific range of knowledge, which provides users fast access to relevant knowledge. However, traditional FAQ service is usually provided by static webpages which has many limitations. Therefore, how to properly manage and plan FAQs for some specific domain knowledge is an important issue.
Our research takes IPv6 related knowledge as an example to explore how to establish a structured multi-dimensional FAQ Knowledge Query System. For flexibility, we use the native XML-based database(eXist) to store these XML files. On the other hand, we proposed a method using RDF/OWL documents to depict the classifications, and allow users to search from multiple dimensions. Furthermore, we provide concept map FAQ search to assist users in comprehending the searched knowledge. This research combines Semantic Web technologies to enhance the efficiency of the management of FAQs and allow users to obtain the information more accurately.

碩士<br>元智大學<br>資訊管理研究所<br>93<br>In the internet era, the growing network bandwidth and the low system equipment cost trigger the booming development of internet application. The information needed to be effectively centralized managed, in order to handle the increasing complexity of system hardware and software.
Nowadays, the typical database application is so called the relational database. Such scheme has its main advantage in defining the structural type data; with respect to the un-structural type data, which is normally been stored in documental format, is unable to be updated and queried. This causes restriction in document management.
A new database scheme called the native XML database, which not only stores un-structural type directly in integer XML document, but also provides effective query mechanism. This research topic is to apply the information (hardware & software) management system on site, through the server program of native XML database of Oracle 9i, it can query and update many XML document simultaneously; besides, it can leverage the validation process on integrating XML Schema to confine the XML document effectively, and improve the performance of programming development and execution.

碩士<br>國立臺灣師範大學<br>資訊工程研究所<br>97<br>Due to the advance of computer technology and the rapid growth of multimedia applications, a huge quantity of video contents are available for browsing in our daily life. Management of video clips in proper classification schema is becoming more important. Therefore, the development of video content management registry/reposit-
ory(VCMRR) which aims at providing a friendly user-interface and an efficient retrieval mechanism is an urgent issue.
In this thesis, we attempt to use Semantic Web and native XML-based database (eXist) to enrich the capability of VCMRR. We proposed using RDF/OWL documents to depict video contents and storing them in the eXist database. Users can create the RDF/OWL document for a newly uploaded video clip. This enables users to describe the video contents in more effective and intelligent way. Our system also facilities the search of video contents using XQuery and RDF/OWL. Moreover, we also integrate Synchronized Multimedia Integration Language (SMIL) and Windows Media Server (WMS) in our VCMRR. It not only supports on-demand and broadcast mode to watch the video contents but also enables users to schedule their playing list whatever they want.

Full textAbstract:
碩士<br>國立臺灣師範大學<br>資訊工程研究所<br>98<br>Owing to the large amount of character set for Chinese characters, such as 4000 characters are covered in the Chinese class of an elementary school. The production and management of Chinese character digital courseware has been plagued Chinese language teachers for many years. Traditional static digital coursewares on the Chinese language are difficult to meet the current demand for both e-learning and modern teachers. Therefore XML technology is introduced into the production and management of Chinese character digital teaching materials.
Our research uses the structural merits of XML files to develop Chinese character courseware material storage format, and uses native XML database (eXist) to store these Chinese character XML files. This study also uses Web service technologies to retrieve information from different repositories. Our system also includes Chinese character authoring tool, Moodle e-learning courseware management system and Web services of Master Ideographs Seeker website developed by the government, to establish an effective Chinese character repository system. The Chinese character authoring tool can provide Chinese language teachers to produce their own courseware, and real-time access to eXist database is also provided for teachers to save their own coursewares. Moodle open source courseware management system is integrated in our system to provide the presentation of Chinese character courseware. Finally, our system also implements the remote query Master Ideographs Seeker website’s Web Services to retrieve unusual words. Our system has the following merits including open standards, repository federation, and object-oriented based Chinese character storage.

Full textAbstract:
碩士<br>龍華科技大學<br>商學與管理研究所碩士班<br>91<br>With rapid progress in computer and network technology, more and more documents are published, indexed and stored in digital formats. Therefore the requirement for transferring information using computer network increases substantially. In order to improve the readability of the transferred data, people in information industry begin to use XML for interpretating data and redefining the formats for Electronic Data Interchange. However, because almost all library automation systems use a relational database to store data, data conversions should be performed before transferring XML data and after receiving XML data. Moreover, both the early used MAChine Readable Cataloguing and the newly adopted XML formats have highly hierarchical structures which are not suitable for Relational Data Model, resulting in various problems related to system analysis, data association, programming and system maintenance.
This research developed an Online Public Access Catalog prototype system based on object oriented and XML database technologies. We then compared this system with a previously developed system which has the same functionalities but with a relational database. The comparison focused on developing frameworks, data models, conversions of book catalogues and system maintenance. We found that due to the hierarchical structure of book catalogues which matches the data model of a XML database, the system with XML database turned out better than that with a relational database. Our work of implementing the prototype system with a XML database is a good reference for developing digital libraries in the future.

Full textAbstract:
碩士<br>朝陽科技大學<br>資訊管理系碩士班<br>91<br>With the advancement of technology and popularity of applications in enterprises’ information system, greater and greater amount of data is generated everyday. To properly store and access these data, database applications have come into play and become crucial. The main task of data mining is to help enterprises make their decisions by extracting useful information from the large amount of complicated data storage for reference, so this is why data mining has been recently paid more attention than ever. Also, more storage media for data is required for the increasing amount of data. For unlimited needs of increasing amount of data, it will be wise to provide an efficient data compression technique to reduce the cost.
The thesis proposes the related research on data mining. First of all, it is different from data mining fields based primarily on relational database. We propose a data mining method for native XML database. It can extract some knowledge from native XML database. Secondly, propose a semantic association rule – the rule that is extracted from data mining method. Convert it to the semantic association rule from the proposed procedures so as to make it more legible and easier to users as reference. Finally, propose a database compression using association rules mining. The method compresses the database for reducing the cost of storage. And from the association rules mining, it finds the association among these data. These association rules are further taken as reference for the organizations when making their strategic steps.

Full textAbstract:
碩士<br>大同大學<br>資訊經營學系(所)<br>92<br>In knowledge economy era, with the fast growth on WWW, the emerging web services and customer relationship management (CRM) issues are being widely concerned. Many hospitals also eager to conduct their own CRM system to provide personal service or discover some metadata that new customers may have. In a series of adverse situation about medical policy, the only way to deal with the problem is to expand their services. Once the amount of service is increased, huge data will be accompanied. The demand for data integration is rapidly becoming larger as more and more information sources appear in medical information database. In the light of the extracted information from medical database, we can use it to hold the relationship between the medical personnel and the customers. The more faithfulness we consolidate, the more competence we raise.
The objective of thesis is to develop a hospital marketing decision support system which utilizes the essence of knowledge sharing and related technique to explore XML-formatted data from the so-called native XML database. With the help of a case-based model, the applied result will assist hospital marketing decision-makers in making their decisions to meet customers’ requirements and cater for the marketing strategy tendency. Our research will contribute not only to the hospital marketing decision support but also to any related applications where the knowledge issue and native XML database are concerned.

Full textAbstract:
碩士<br>朝陽科技大學<br>資訊管理系碩士班<br>93<br>The popularity of XML results in producing huge numbers of XML documents. Thus, native XML databases are developed and designed to store the great quantity of XML documents. However, most techniques of association rule mining only can be applied to transaction databases, such as Apriori algorithm, H-mine algorithm, and FP-tree algorithm, and so on. Therefore, to develop an approach of association rule mining on native XML databases is a great important research.
Currently, the FP-growth based on an FP-tree algorithm performs more efficiently than other methods of association rules mining, but it cannot be applied to native XML databases. Hence, we adaptive an improving FP-tree algorithm called Frequent Pattern Split method, simply FP-split, for fast association rule mining from native XML databases.
The proposed FP-split method explores association rules of character data and tags in XML documents by parsing DTD or XML schema. Unlike XQuery, FP-split method can easily aid users to extract important and complete information from XML documents without needing to understand both the structure of XML documents and their corresponding syntax.
In this paper, we prove that the FP-split method is time-efficient for mining association rules from native XML databases by experiment with various parameters, such as various minimum supports, different number of items, and large amount of data. In addition, we also implement a lot of experiments to show that our proposed method performs better than FP-tree construction algorithm in transaction database.

Full textAbstract:
碩士<br>國立臺灣師範大學<br>資訊工程研究所<br>98<br>Due to the advance of computer technology and the rapid growth of multimedia applications, it is getting popular for people to share video contents on the internet. However, the complexities of video applications have made video contents suffer from the problem of multiple format and the difficulty for searching. Therefore, the development of video content management registry/repository(VCMRR) which aims at providing a friendly user-interface and an efficient retrieval mechanism is an urgent issue.
In this thesis, we use Silverlight, eXist, RDF/OWL and SMIL to develop a VCMRR system, which has the ability to store and classify video contents. We develop a XML storage mechanism for video package. Users can upload and search these video contents in VCMRR. Two kinds of video package formats, SMIL and playlist are supported in our system. Using video package we can extend the functionality of video file to provide multimedia functions such as interactive and picture in picture video, etc. Besides, we develop an advertisement model to embed an advertisement video before or after a scheduled video. In order to improve the efficiency of video searching, we use Semantic Web technology to associate RDF/OWL document with video contents and provide a classification scheme for video content. In our system, Silverlight is also included to provide a decent interactive user-interface. Moreover, we also integrate Media Server to broadcast scheduled video contents. Finally, we use native XML-based database to store the XML-format video for searching and management.

Full textAbstract:
碩士<br>靜宜大學<br>資訊管理學系研究所<br>92<br>XML is becoming a new standard for data representation and exchange on the Web. With the proliferation of XML documents in the Web, it is necessary to store and manage them efficiently.
An XML-Enabled data management system, built on top of relational systems, has been finding conflicts in storing XML documents, forcing XML into tables or into CLOBs is inefficient. A Native XML database, storing XML documents in their natural tree structure, eliminates the problems related to relational database management system and offers significant additional advantages.
The major purpose of this paper is to design a querying system of university laws by using Tamino Native XML database. It is to construct law data structures and maintain contents by using Tamino Schema Editor and X-Plorer, also develops a program to transfer laws into XML. Moreover, use a standard web-based interface to access laws with Tamino X-Application and Tamino XQuery4 functions. Therefore, it can store laws permanently with a standard schema and support well the retrieval functions of traditional databases, full text search and XML features, in order to improve the search quality of laws and reduces the obstacles to integrated and sharing data among diverse systems.

碩士<br>南華大學<br>資訊管理學研究所<br>91<br>The development of the Internet, we can find that more and more data were processed directly on the Internet. In recently, many of data were presented by XML format; it was differ from structure data of relation database in the past.
The traditional methods of document management not efficient in manage XML document due to different data structure. Conversely, the significant advantage of XML lies in it can define its own tags and transmission among organizations through the Internet. In addition, native XML database can not only store the XML document completely but also support the complex XML document; however, it can't support other document format. Therefore, some problems will occur when transform and manage XML document between relation and native XML database. Our research will discuss and provide the best solution for this issue. We will build a XML document management platform to obtain the better improvement in data integration between relation and native XML database by using UML analysis and find the related classifications and operation processes.

Full textAbstract:
A general XML index can itself be sizable leading to low efficiency. To alleviate this predicament, frequently asked queries can be indexed by a database system. They are referred to as views. Answering queries using materialized views is always cheaper than evaluating over the base data. Traditional techniques solve this problem by considering only a single view. We approach this problem by exploiting the potential relationships of multiple views, which can be used together to answer a given query. Experiments show that significant performance gain can be achieved from multiple views.<br>A XML query can be decomposed to a sequence of structural joins (e.g., parent/child and ancestor/descendant) and content joins. Thus, structural join optimization is a key to improving join-based evaluation. We optimize structural join with two orthogonal methods: partition-based method exploits the spatial specialities of XML encodings by projecting them on a plane; and location-based method improves structural join by accurately pruning all irrelevant nodes, which cannot produce results.<br>As XML (eXtensible Markup Language) becomes a universal medium for data exchange over the Internet, efficient XML query processing is now the focus of considerable research and development activities. This thesis describes works toward efficient XML query evaluation and optimization in native XML databases.<br>XML indexes are widely studied to evaluate XML queries and in particular to accelerate join-based approaches. Index-based approaches outperform join-based approaches (e.g., holistic twig join) if the queries match the index. Existing XML indexes can only support a small set of XML queries because of the varieties in XML query representations. A XML query may involve child-axis only, both child-axis and branches, or additional descendant-or-self-axis but only in the query root. We propose novel indexes to efficiently support a much wider range of XML queries (with /, //, [], *).<br>Tang, Nan.<br>"December 2007."<br>Advisers: Kam-Fei Wong; Jeffrey Xu Yu.<br>Source: Dissertation Abstracts International, Volume: 69-08, Section: B, page: 4861.<br>Thesis (Ph.D.)--Chinese University of Hong Kong, 2007.<br>Includes bibliographical references (p. 152-163).<br>Electronic reproduction.

Full textAbstract:
碩士<br>朝陽科技大學<br>資訊管理系碩士班<br>95<br>XML-based applications widely apply to data exchange in EC and digital archives. However, the study of compressing Native XML databases has been surprisingly neglected, especially for the huge amount of data and the rapidly updatable database. These two factors give rise to our interest, and motivate us to develop an approach to efficiently compress native XML databases and dynamically maintaining a set of compression rules when insertion, deletion, or modification functions in databases.
This approach is to utilize data mining technology and association rules, to mine all frequent element sets. The approach contributes to the native XML database both in exploring frequent character data sets and frequent tag sets and in lossless compression, respectively. The proposed method contains three steps. The first step is to construct a frequent tag and character data pattern split tree (FTCP-split tree) to fast generate the frequent element sets. The second step is to convert these frequent element sets into compression rules, which would be used to compress native XML databases. In the third step, we select the most efficient compression rules by four heuristic compression methods. The question which we must consider next is how to dynamically maintain XML database compression when XML documents are inserted, deleted, or modified. We propose a compression approach with dynamic maintenance on native XML databases called Incremental FTCP-split approach to deal with it. The results of experiment indicate that the compression rate of our research is higher than the common compression software as ZIP and RAR. In addition, the results can also account for the high efficiency of dynamic maintenance in our research. As a result of our research adopted association mining approach so it will suit for discover the business intelligence from the native XML databases of enterprise in the future.
