- Abstract
- On a scientific concept hierarchy, a parent concept may have a few attributes, each of which has multiple values being a group of child concepts. We call these attributes facets: classification has a few facets such as application (e.g., face recognition), model (e.g., svm, knn), and metric (e.g., precision). In this work, we aim at building faceted concept hierarchies from scientific literature. Hierarchy construction methods heavily rely on hypernym detection, however, the faceted relations are parent-to-child links but the hypernym relation is a multi-hop, i.e., ancestor-to-descendent link with a specific facet "type-of". We use information extraction techniques to find synonyms, sibling concepts, and ancestor-descendent relations from a data science corpus. And we propose a hierarchy growth algorithm to infer the parent-child links from the three types of relationships. It resolves conflicts by maintaining the acyclic structure of a hierarchy.

- Abstract
- The successes of information retrieval (IR) in recent decades were built upon bag-of-words representations. Effective as it is, bag-of-words is only a shallow text understanding; there is a limited amount of information for document ranking in the word space. This dissertation goes beyond words and builds knowledge based text representations, which embed the external and carefully curated information from knowledge bases, and provide richer and structured evidence for more advanced information retrieval systems. This thesis research first builds query representations with entities associated with the query. Entities' descriptions are used by query expansion techniques that enrich the query with explanation terms. Then we present a general framework that represents a query with entities that appear in the query, are retrieved by the query, or frequently show up in the top retrieved documents. A latent space model is developed to jointly learn the connections from query to entities and the ranking of documents, modeling the external evidence from knowledge bases and internal ranking features cooperatively. To further improve the quality of relevant entities, a defining factor of our query representations, we introduce learning to rank to entity search and retrieve better entities from knowledge bases. In the document representation part, this thesis research also moves one step forward with a bag-of-entities model, in which documents are represented by their automatic entity annotations, and the ranking is performed in the entity space.
This proposal includes plans to improve the quality of relevant entities with a co-learning framework that learns from both entity labels and document labels. We also plan to develop a hybrid ranking system that combines word based and entity based representations together with their uncertainties considered. At last, we plan to enrich the text representations with connections between entities. We propose several ways to infer entity graph representations for texts, and to rank documents using their structure representations. This dissertation overcomes the limitation of word based representations with external and carefully curated information from knowledge bases. We believe this thesis research is a solid start towards the new generation of intelligent, semantic, and structured information retrieval.

- Abstract
- By the explosion of possibilities for a ubiquitous content production, the information overload problem reaches the level of complexity which cannot be managed by traditional modelling approaches anymore. Due to their pure syntactical nature traditional information retrieval approaches did not succeed in treating content itself (i.e. its meaning, and not its representation). This leads to a very low usefulness of the results of a retrieval process for a user's task at hand. In the last ten years ontologies have been emerged from an interesting conceptualisation paradigm to a very promising (semantic) modelling technology, especially in the context of the Semantic Web. From the information retrieval point of view, ontologies enable a machine-understandable form of content description, such that the retrieval process can be driven by the meaning of the content. However, the very ambiguous nature of the retrieval process in which a user, due to the unfamiliarity with the underlying repository and/or query syntax, just approximates his information need in a query, implies a necessity to include the user in the retrieval process more actively in order to close the gap between the meaning of the content and the meaning of a user's query (i.e. his information need). This thesis lays foundation for such an ontology-based interactive retrieval process, in which the retrieval system interacts with a user in order to conceptually interpret the meaning of his query, whereas the underlying domain ontology drives the conceptualisation process. In that way the retrieval process evolves from a query evaluation process into a highly interactive cooperation between a user and the retrieval system, in which the system tries to anticipate the user's information need and to deliver the relevant content proactively. Moreover, the notion of content relevance for a user's query evolves from a content dependent artefact to the multidimensional context-dependent structure, strongly influenced by the user's preferences. This cooperation process is realized as the so-called Librarian Agent Query Refinement Process. In order to clarify the impact of an ontology on the retrieval process (regarding its complexity and quality), a set of methods and tools for different levels of content and query formalisation is developed, ranging from pure ontology-based inferencing to keyword-based querying in which semantics automatically emerges from the results. Our evaluation studies have shown that the possibilities to conceptualize a user's information need in the right manner and to interpret the retrieval results accordingly are key issues for realizing much more meaningful information retrieval systems.

- Abstract
- An ontology is a description (like a formal specification of a program) of concepts and relationships that can exist for an agent or a community of agents. The concept is important for the purpose of enabling knowledge sharing and reuse. The Handbook on Ontologies provides a comprehensive overview of the current status and future prospectives of the field of ontologies. The handbook demonstrates standards that have been created recently, it surveys methods that have been developed and it shows how to bring both into practice of ontology infrastructures and applications that are the best of their kind.

- Abstract
- In der Informatik sind Ontologien formale Modelle eines Anwendungsbereiches, die die Kommunikation zwischen menschlichen und/oder maschinellen Akteuren unterstützen und damit den Austausch und das Teilen von Wissen in Unternehmen erleichtern. Ontologien zur strukturierten Darstellung von Wissen zu nutzen hat deshalb in den letzten Jahren zunehmende Verbreitung gefunden. Schon heute existieren weltweit tausende Ontologien. Um Interoperabilität zwischen darauf aufbauenden Softwareagenten oder Webservices zu ermöglichen, ist die semantische Integration der Ontologien eine zwingendnotwendige Vorraussetzung. Wie man sieh leicht verdeutlichen kann, ist die rein manuelle Erstellung der Abbildungen ab einer bestimmten Größe. Komplexität und Veränderungsrate der Ontologien nicht mehr ohne weiteres möglich. Automatische oder semiautomatische Technologien müssen den Nutzer darin unterstützen. Das Integrationsproblem beschäftigt Forschung und Industrie schon seit vielen Jahren z. B. im Bereich der Datenbankintegration. Neu ist jedoch die Möglichkeit komplexe semantische Informationen. wie sie in Ontologien vorhanden sind, einzubeziehen. Zur Ontologieintegration wird in diesem Kapitel ein sechsstufiger genereller Prozess basierend auf den semantischen Strukturen eingeführt. Erweiterungen beschäftigen sich mit der Effizienz oder der optimalen Nutzereinbindung in diesen Prozess. Außerdem werden zwei Anwendungen vorgestellt, in denen dieser Prozess erfolgreich umgesetzt wurde. In einem abschließenden Fazit werden neue aktuelle Trends angesprochen. Da die Ansätze prinzipiell auf jedes Schema übertragbar sind, das eine semantische Basis enthält, geht der Einsatzbereich dieser Forschung weit über reine Ontologieanwendungen hinaus.

- Abstract
- Menschliches Wissen und menschliche Sprache sind aufeinander bezogen und voneinander abhängig. Dies gilt auch und gerade bei den Bemühungen, Sprache und Wissen computergestützt so zu verarbeiten, dass für Menschen nutzbare maschinelle Wissensverarbeitung stattfindet. Jenseits von eher akademischen "Laborversuchen" hat wissenschaftliche Forschungsarbeit auf diesem Gebiet die Verfügbarkeit umfangreicher, gepflegter und sauber codierter Wissensbasen sowohl der verwendeten Sprache als auch des abgebildeten Gegenstands zur Voraussetzung. In einem Forschungsprojekt der Firma Brockhaus Duden Neue Medien GmbH gemeinsam mit namhaften wissenschaftlichen Partnern, u.a. dem Fraunhofer-IPSI, dem IICM der TU Graz, dem IAI der Universität Saarbrücken und dem KNOW-Center, Graz, wurde diese Herausforderung erfolgreich angegangen. Für eine neue digitale Brockhaus-Auflage wurden Informationsrepräsentations- und Retrievaltechniken entwickelt, die nicht auf domänenspezifischen Beschränkungen beruhend den gesamten enzyklopädischen Wissenskreis abdecken. Die entwickelten Formalismen erwiesen sich nicht nur zur Abfrage des enzyklopädischen Wissens in natürlicher Sprache als geeignet, sondern konnten auch darauf basierend neuartige Formen der Visualisierung von Wissenszusammenhängen implementiert werden. Die Ergebnisse zeigen zum einen Möglichkeiten erfolgreichen semantischen Retrievals ohne extensiven Einsatzformaler Metacodierungen, zum anderen weisen sie den Weg und die nächsten Schritte bei der Entwicklung noch leistungsfähigerer Mensch-Maschine-Schnittstellen.

- Abstract
- An increasing number of recent information retrieval systems make use of ontologies to help the users clarify their information needs and come up with semantic representations of documents. A particular concern here is the integration of these semantic approaches with traditional search technology. The research presented in this paper examines how ontologies can be efficiently applied to large-scale search systems for the web. We describe how these systems can be enriched with adapted ontologies to provide both an in-depth understanding of the user's needs as well as an easy integration with standard vector-space retrieval systems. The ontology concepts are adapted to the domain terminology by computing a feature vector for each concept. Later, the feature vectors are used to enrich a provided query. The whole retrieval system is under development as part of a larger Semantic Web standardization project for the Norwegian oil & gas sector.

- In der Finanzwirtschaft mit ihren automatisierten Handelssystemen (auf Basis technischer Ontologien) wird beispielsweise inzwischen bei außergewöhnlichen Kursbewegungen der Börse der automatische Handel unterbrochen, so dass dann auf pragmatisch-natürlichsprachliche Weise nach den Gründen für die Ausschläge gesucht werden kann. Aus Sicht der technischen Ontologien wäre eine solche Unterbrechung des Computerhandels (zur Beruhigung der Märkte) nicht zwingend erforderlich, aber sie ist sehr sinnvoll aus einer außerhalb der technischen Ontologie stehenden Perspektive, die alleine nach Sinn und Bedeutung stabiler Kursverläufe zu fragen imstande ist. Der hier sich abzeichnende ,pragmatic turn' beim Einsatz technischer Ontologien ist auch in vielfältiger Weise in Trends wie z.B. Folksonomies, Sozialen Netzwerken und Open-SourceEntwicklergruppen zu erkennen. Diese Gemeinschaften zeichnen sich dadurch aus, dass sie zwar (technische) Ontologien einsetzen, diese jedoch in intensive soziale Austauschprozesse einbinden, in denen die formalen Wissensrepräsentationen mit situativer Bedeutung und Sinn versehen und angereichert werden. Dieser Trend zu ,weicheren' Formen der Nutzung von (technischen) Ontologien scheint nach aktuellem Wissensstand auf jeden Fall in der Praxis erfolgversprechender als die anfänglichen Hoffnungen des Semantic Web oder vollständiger (technischer) Ontologien - ganz abgesehen vom laufenden Pflegeaufwand 'vollständiger' technischer Ontologien.
In diesem Sinne könnte auch Wissensaustausch und Wissensmanagement in Organisationen auf Basis (technischer) Ontologien eine neue Bedeutung erhalten im Sinne einer gezielten Ermöglichung sozialer Austauschprozesse unter Nutzung formaler Wissensrepräsentationen statt der technologiezentrierten Sichtweise, wonach bereits das Wissensrepräsentationssystem mit Wissensaustausch gleichzusetzen wäre. Letztlich haben die in (formalen) Wissensrepräsentationssystemen dargestellten technischen Ontologien alleine nämlich keine tiefere Bedeutung und auch keinen Sinn. Beides entsteht erst durch eine entsprechende Einbettung und Interpretation dieser Repräsentationen in konkreten lebensweltlichen Zusammenhängen. Und was die Menschen in diesem Interpretations-und Rekontextualisierungsprozess dann aus den zeichenvermittelten technischen Ontologien machen, ist glücklicherweise eine Frage, die sich einer vollständigen Behandlung und Abbildung in technischen Ontologien entzieht."

- Abstract
- Mining product reviews and sentiment analysis are of great significance, whether for academic research purposes or optimizing business strategies. We propose a feature-level sentiment analysis framework based on rules parsing and fine-grained domain ontology for Chinese reviews. Fine-grained ontology is used to describe synonymous expressions of product features, which are reflected in word changes in online reviews. First, a semiautomatic construction method is developed by using Word2Vec for fine-grained ontology. Then, featurelevel sentiment analysis that combines rules parsing and the fine-grained domain ontology is conducted to extract explicit and implicit features from product reviews. Finally, the domain sentiment dictionary and context sentiment dictionary are established to identify sentiment polarities for the extracted feature-sentiment combinations. An experiment is conducted on the basis of product reviews crawled from Chinese e-commerce websites. The results demonstrate the effectiveness of our approach.

- Abstract
- The Future of Information Architecture examines issues surrounding why information is processed, stored and applied in the way that it has, since time immemorial. Contrary to the conventional wisdom held by many scholars in human history, the recurrent debate on the explanation of the most basic categories of information (eg space, time causation, quality, quantity) has been misconstrued, to the effect that there exists some deeper categories and principles behind these categories of information - with enormous implications for our understanding of reality in general. To understand this, the book is organised in to four main parts: Part I begins with the vital question concerning the role of information within the context of the larger theoretical debate in the literature. Part II provides a critical examination of the nature of data taxonomy from the main perspectives of culture, society, nature and the mind. Part III constructively invesitgates the world of information network from the main perspectives of culture, society, nature and the mind. Part IV proposes six main theses in the authors synthetic theory of information architecture, namely, (a) the first thesis on the simpleness-complicatedness principle, (b) the second thesis on the exactness-vagueness principle (c) the third thesis on the slowness-quickness principle (d) the fourth thesis on the order-chaos principle, (e) the fifth thesis on the symmetry-asymmetry principle, and (f) the sixth thesis on the post-human stage.

- Abstract
- Der Beitrag berichtet über Grundideen in der Explorationsphase des Projektes kPeer (Knowledge Peers). Gegenstand ist die dezentrale Organisation, Integration und Aggregation von Wissen mit semantischen Wissenstechnologien in verteilten, heterogenen Umgebungen Dabei sollen Wissensarbeiter, die dezentral und voneinander unabhängig Wissen gemäß lokaler Schemata ausdrücken und organisieren, emergent zusammenwirken, so dass sich eine nützliche gemeinsame Wissensorganisation ergibt. Zudem sollen Aussagen zum selben Aussagegegenstand, die digitalisiert vorliegen, virtuell zusammengeführt werden, um so neue wissensintensive Produkte und Dienstleistungen zu ermöglichen. Als Inspirationsquelle für beabsichtigte Anwendungen im verteilten Wissensmanagement (DKM) und e-business werden Beispiele der Wissensintegration aus dem Bereich Digitale Bibliotheken und Kulturelles Erbe herangezogen.

- Abstract
- In this paper the possibility to develop a richer relational structure for thesauri is explored and described. The development of a new environmental thesaurus - EARTh (Environmental Applications Reference Thesaurus) - is serving as a case study for exploring the refinement of thesaurus relational structure by specialising standard relationships into different subtypes. Together with benefits and opportunities, implications and possible challenges that an expanded set of thesaurus relations may cause are evaluated.

- Abstract
- Last word ontological thought and practice is exemplified on an axiomatic framework [a model for an Integrative Cross-Language Ontology (ICLO), cf. Poli, R., Schmitz-Esser, W., forthcoming 2007] that is highly general, based on natural language, multilingual, can be implemented as topic maps and may be openly enhanced by software available for particular languages. Basics of ontological modelling, conditions for construction and maintenance, and the most salient points in application are addressed, such as cross-language text mining and knowledge generation. The rationale is to open the eyes for the tremendous potential of terminology-based ontologies for principled Knowledge Organization and the interchange and reuse of formalized knowledge.
