availability of a critical mass of metadata for the web content, associated with the respective formal knowledge about the world. {W}e claim that the {S}emantic {W}eb, at its current stage of development, is in a state of a critical need of metadata generation and usage schemata that are specific, well-defined and easy to understand. {T}his paper introduces our vision for a holistic architecture for semantic annotation, indexing, and retrieval of documents with regard to extensive semantic repositories. {A} system (called {KIM}), implementing this concept, is presented in brief and it is used for the purposes of evaluation and demonstration. {A} particular schema for semantic annotation with respect to real-world entities is proposed. {T}he underlying philosophy is that a practical semantic annotation is impossible without some particular knowledge modelling commitments. {O}ur understanding is that a system for such semantic annotation should be based upon a simple model of real-world entity classes, complemented with extensive instance knowledge. {T}o ensure the efficiency, ease of sharing, and reusability of the metadata, we introduce an upper-level ontology (of about 250 classes and 100 properties), which starts with some basic philosophical distinctions and then goes down to the most common entity types (people, companies, cities, etc.). {T}hus it encodes many of the domain-independent commonsense concepts and allows straightforward domain-specific extensions. {O}n the basis of the ontology, a large-scale knowledge base of entity descriptions is bootstrapped, and further extended and maintained. {C}urrently, the knowledge bases usually scales between 105 and 106 descriptions. {F}inally, this paper presents a semantically enhanced information extraction system, which provides automatic semantic annotation with references to classes in the ontology and to instances. {T}he system has been running over a continuously growing document collection (currently about 0.5 million news articles), so it has been under constant testing and evaluation for some time now. {O}n the basis of these semantic annotations, we perform semantic based indexing and retrieval where users can mix traditional information retrieval ({IR}) queries and ontology-based ones. {W}e argue that such large-scale, fully automatic methods are

{W}hich fragment of {OWL} can be implemented in logic databases ? {W}e invent a strategy to identify the fragment, which is based on the translation of {DL} axioms into first-order logic, followed by a transformation into a conjunction of {H}orn formulae. {T}hese formulae can be translated into the different {L}ogic {P}rogramming languages which are supported by logic databases. ? {W}hat are the theoretical properties of the fragment ? {W}e define {D}escription {L}ogic {P}rograms ({DLP}) as a family of new ontology languages {L}i, which precisely contains the fragment. {W}e utilize {DLP} to study the theoretical properties of the fragment. {I}n particular, we show that we can solve {AB}ox related reasoning problems, independent of the {TB}ox, with a low polynomial complexity {O}(|{ADLP} i<=2 |)4 in the size of the {DLP} {AB}ox {ADLP} . ? {H}ow can {DL} reasoning be reduced to operations on logic databases ? {W}e show which and how{DL} reasoning problems can be reduced to operations on logic databases and identify the limitations of the reduction. ? {H}ow useful is the related fragment as a practical {W}eb ontology language ? {W}e answer this question by showing two separate hypotheses. {H}ypothesis 1: {T}he fragment is sufficient to express most available {W}eb ontologies. {W}e analyze the largest currently available collection of {W}eb ontologies and check which fragment of those ontologies can be expressed in {DLP}. {W}e quantify most in two respects. {F}irstly, we show that the different {DLP} languages suffice to express 77 % ({L}0 ) ? 87 % ({L}3) of the analyzed ontologies. {S}econdly, we could express 93% ({L}0) ? 99 % (({L}3)) of the individual axioms in the analyzed ontologies. {H}ypothesis 2: {W}e can efficiently and scalably reason with {DLP}. {W}e will show that logic databases not only exhibit satisfactory performance for {AB}ox-related reasoning problems in {DLP} knowledge bases but also compare favorably with the only state of the art {DL} reasoner which supports {AB}ox-reasoning. ? {H}ow can we improve the performance of {AB}ox-related reasoning problems ? {C}ertain language features of {OWL} (such as equality) deteriorate the performance of {AB}ox-reasoning severely. {W}e propose the materialization of knowledge bases to store computed entailments and speed up reasoning. {W}e show howwe can maintain a materialization incrementally in the case of changes. {P}ut together, the results developed in this thesis allow scalable and practical solutions to {AB}ox-related reasoning problems for {OWL}-based applications. {O}ur results are based on delegating {AB}ox reasoning problems to logic databases. {T}he thesis covers all necessary stages to obtain this delegation, starting from the identification of the (sub)languages for which this delegation can be achieved, via the theoretical analysis of the properties of these languages, to the assessment of the performance obtained by the delegation. {E}ven though logic databases have been used for {S}emantic {W}eb applications from the early days of the {S}emantic {W}eb, no comprehensive solution, which guarantees the correctness of the obtained answers, has been presented before for {OWL} or its predecessors1.}, owner = {seebi}, pdf = {volz-r-2004--a.pdf}, url = {http://www.ubka.uni-karlsruhe.de/cgi-bin/psview?document=2004/wiwi/2&format=0&search=%2f2004%2fwiwi%2f2}, } @INPROCEEDINGS{volz-r-2003--a, author = {Raphael Volz and Daniel Oberle and Steffen Staab and Boris Motik}, title = {K{AON} {SERVER} - {A} {S}emantic {W}eb {M}anagement {S}ystem}, booktitle = {Alternate {T}rack {P}roceedings of the {T}welfth {I}nternational {W}orld {W}ide {W}eb {C}onference, {WWW}2003, {B}udapest, {H}ungary, 20-24 {M}ay 2003}, year = {2003}, publisher = ACM, abstract = {The growing use of ontologies in applications creates the need for an infrastructure that allows developers to more easily combine different software modules like ontology stores, editors, or inference engines towards comprehensive ontology-based solutions. {W}e call such an infrastructure {O}ntology {S}oftware {E}nvironment. {T}he papers discusses requirements and design issues of such an {O}ntology {S}oftware {E}nvironment. {I}n particular, we present this discussion in light of the ontology and (meta)data standards that exist in the {S}emantic{W}eb and present our corresponding implementation, the {KAON} {SERVER}.}, groupsearch = {0}, keywords = {RDFapps}, owner = {seebi}, pdf = {volz-r-2003--a.pdf}, } @TECHREPORT{wahl-m-1997--a, author = {Mark Wahl and Timothy A Howes and S.
