Inhaltlich unveränderte Neuauflage. Wissenschaftliche Publikationen im World Wide Web ausfindig zu machen, ist nicht immer einfach. Viele Dokumente lassen sich nicht über herkömmliche Suchmaschinen finden, da diese aufgrund der Größe des Webs nicht alle Webseiten und Dokumente in ihren Index aufnehmen können. Zudem kann ein Dokument, welches heute noch unter einer bestimmten URL zu finden ist, morgen schon nicht mehr dort abrufbar sein kann. Ein weiteres Problem bei der Suche im Web ist der Einsatz von Keyword-basierten Suchmaschinen. Zum finden von Publikationen zu einem bestimmten Thema wäre eine auf Dokumentenähnlichkeit basierende Suche, die ausgehend von einem bereits vorhandenen Dokument andere ähnliche Dokumente findet, einfacher. In diesem Buch wird das System DocAssistant entwickelt, welches eine Population von autonomen Agenten zur Suche und Klassifizierung von Dokumenten im WWW einsetzt. Durch den Einsatz dieser Techniken kann die Suche nach wissenschaftlichen Publikationen im Web unterstützt und verbessert werden. Das Buch richtet sich an Wissenschaftler und Softwareentwickler aus den Bereichen Information Retrieval und Künstliche Intelligenz.

Graph-structured databases are widely prevalent, and the problem of effective search and retrieval from such graphs has been receiving much attention recently. For example, the Web can be naturally viewed as a graph. Likewise, a relational database can be viewed as a graph where tuples are modeled as vertices connected via foreign-key relationships. Keyword search querying has emerged as one of the most effective paradigms for information discovery, especially over HTML documents in the World Wide Web. One of the key advantages of keyword search querying is its simplicity users do not have to learn a complex query language, and can issue queries without any prior knowledge about the structure of the underlying data. This book presents techniques for user-friendly, high quality and efficient searching of graph structured databases. The methods and techniques presented should help shed some light on this new and exciting field, and should especially be useful to professionals in Computer science or Information technology fields, or anyone else who may be considering a research career in the area of Databases and Information Retrieval.

Efficient Approaches for Querying XML Data
59,00 € *
ggf. zzgl. Versand

With the emergence of the World Wide Web and online businesses, business XML databases are increasingly being queried directly by users. This book focuses on three aspects related to querying of XML data, as follows: (1) Improving accuracy of XML keyword queries by modeling the contexts of XML elements. Most current research is focused on building relationships between data elements based solely on their labels and proximity to one another, while overlooking the contexts of the elements. This may lead to erroneous results. This book presents different context-driven techniques that avoid this problem. (2) Enhancing XML-based personalized search by using group profiling to determine individual preferences. Group profiling can be an efficient retrieval mechanism, where a user profile is inferred from the profile of the social groups to which the user belongs. A social group is defined based on ethnic, cultural, religious, or other characteristics. (3) Improving performance of distributed XML querying by caching of frequently-used query results. For each of these areas, we developed formal concepts and algorithms that lead to the improved accuracy and performance.

Graph-structured databases are widely prevalent, and the problem of effective search and retrieval from such graphs has been receiving much attention recently. For example, the Web can be naturally viewed as a graph. Likewise, a relational database can be viewed as a graph where tuples are modeled as vertices connected via foreign-key relationships, and a XML database can be represented as a graph with XML elements as nodes and containment or ID-IDREF edges as hyperlinks. Keyword search querying has emerged as one of the most effective paradigms for information discovery, especially over HTML documents in the World Wide Web. One of the key advantages of keyword search querying is its simplicity - users do not have to learn a complex query language, and can issue queries without any prior knowledge about the structure of the underlying data. Since the keyword search query interface is very flexible, queries may not always be precise and can potentially return a large number of query results, especially in large document collections. Consequently, an important requirement for keyword search is to rank the query result. The goal of this book is to present various search techniques.

ggf. zzgl. Versand

Keyword Advertising zählt zu den attraktivsten Werbeformen und beschert den Betreibern von Suchmaschinen im World Wide Web Umsätze in Milliardenhöhe. Technisch gesehen handelt es sich um ein einfaches Verfahren: Die Schaltung einer Werbeeinblendung wird an die Eingabe eines bestimmten Begriffs (Keyword) in die Suchmaske gebunden. Die Werbung erscheint nur dann, wenn nach diesem Begriff gesucht wird. So genannte kontext-sensitive Werbung erfreut sich immer größerer Beliebtheit, denn durch die Verbindung mit vorher definierten Begriffen kann Werbung sehr effizient eingesetzt werden. Der Nutzer einer Suchmaschine zeigt in der Regel Interesse an einem Thema, wenn er nach einem zu diesem Thema gehörenden Begriff im World Wide Web sucht. Juristisch ist Keyword Advertising umstritten, vor allem dann, wenn Marken als Keywords eingesetzt werden. Gerade in jüngster Zeit sind zahlreiche gerichtliche Entscheidungen mit unterschiedlichen Ergebnissen dazu veröffentlichet worden.Der Autor begutachtet die praktizierten Formen kommerzieller Vermarktung von Begriffen als Keywords unter besonderer Berücksichtigung der deutschen und US-amerikanischen Rechtsprechung.

Ontology-Based Query Processing for Global Info...

Today we are witnessing an exponential growth of information accumulated within universities, corporations, and government organizations. Autonomous repositories that store different types of digital data in multiple formats are becoming available for use on the fast-evolving global information systems infrastructure. More concretely, with the World Wide Web and related internetworking technologies, there has been an explosion in the types, availability, and volume of data accessible to a global information system. However, this information overload makes it nearly impossible for users to be aware of the locations, organization or structures, query languages, and semantics of the information in various repositories. br/ Available browsing and navigation tools assist users in locating information resources on the Internet. However, there is a real need to complement current browsing and keyword-based techniques with concept-based approaches. An important next step should be to support queries that do not contain information describing location or manipulation of relevant resources. br/ emOntology-Based Query Processing for Global Information Systems/em describes an initiative for enhancing query processing in a global information system. The following are some of the relevant features: ul li Providing semantic descriptions of data repositories using ontologies; /li li Dealing with different vocabularies so that users are not forced to use a common one; /li li Defining a strategy that permits the incremental enrichment of answers by visiting new ontologies; /li li Managing imprecise answers and estimations of the incurred loss of information. /li /ul In summary, technologies such as information brokerage, domain ontologies, and estimation of imprecision in answers based on vocabulary heterogeneity have been synthesized with Internet computing, representing an advance in developing semantics-based information access on the Web. Theoretical results are complemented by the presentation of a prototype that implements the main ideas presented in this book. br/ emOntology-Based Query Processing for Global Information Systems/em is suitable as a secondary text for a graduate-level course, and as a reference for researchers and practitioners in industry.
