SQL is full of difficulties and traps for the unwary. You can avoid them if you understand relational theory, but only if you know how to put the theory into practice. In this insightful book, author C.J. Date explains relational theory in depth, and demonstrates through numerous examples and exercises how you can apply it directly to your use of SQL.
This second edition includes new material on recursive queries, “missing information” without nulls, new update operators, and topics such as aggregate operators, grouping and ungrouping, and view updating.
Most approaches to topic modeling assume an independence between documents that is frequently violated. We present an topic model that makes use of one or more user-speciﬁed graphs describing relationships between documents. These graph are encoded in the form of a Markov random ﬁeld over topics and serve to encourage related documents to have similar topic structures. Experiments on show upwards of a 10% improvement in modeling performance. of the form of the distance metric used to specify the edge potentials. ...
This book introduces you to the theory of relational databases, focusing on the application of that theory to the design of computer languages that properly embrace it. The book is intended for those studying relational databases as part of a degree course in Information Technology (IT). Relational database
theory, originally proposed by Edgar F. Codd in 1969, is a topic in Computer Science. Codd’s seminal paper (1970) was entitled A Relational Model of Data for Large Shared Data Banks (reference  in Appendix B)....
This book contains a wealth of useful information on current research on viscoelasticity. By covering a broad variety of rheology, non-Newtonian fluid mechanics and viscoelasticity-related topics, this book is addressed to a wide spectrum of academic and applied researchers and scientists but it could also prove useful to industry specialists. The subject areas include, theory, simulations, biological materials and food products among others.
Named entity disambiguation is the task of linking an entity mention in a text to the correct real-world referent predeﬁned in a knowledge base, and is a crucial subtask in many areas like information retrieval or topic detection and tracking. Named entity disambiguation is challenging because entity mentions can be ambiguous and an entity can be referenced by different surface forms.
Views are virtual tables. That means they should be updatable, just as "real" orare. In fact, view updatability isn’t just desirable, it’s crucial, for practical reasons as well as theoretical ones. But view updating has always been a controversial topic. Ever since the relational model first appeared, there has been widespread skepticism as to whether (in general) view updating is even possible.
This paper presents an approach to automatically build a semantic perceptron net (SPN) for topic spotting. It uses context at the lower layer to select the exact meaning of key words, and employs a combination of context, co-occurrence statistics and thesaurus to group the distributed but semantically related words within a topic to form basic semantic nodes. The semantic nodes are then used to infer the topic within an input document. Experiments on Reuters 21578 data set demonstrate that SPN is able to capture the semantics of topics, and it performs well on topic spotting task. ...
The topic of the paper is the problem how to define case relations by semantic predicates. A general principle is outlined, which renders it possible to "calculate" case relations for a given representation of a (verb-)sememe by means of expressions. This principle is based on an assignment of case relations to primitive predicates and modification rules for nested expressions.
We describe the use of a hierarchical topic model for automatically identifying syntactic and lexical patterns that explicitly state ontological relations. We leverage distant supervision using relations from the knowledge base FreeBase, but do not require any manual heuristic nor manual seed list selections. Results show that the learned patterns can be used to extract new relations with good precision.
preconstructed dictionaries or thesauruses. Even in this relatively simplified environment one does not normally undertake a linguistic analysis of any scope. In fact, syntactic and semantic analysis have been used in b i b l i o g r a p h i c information retrieval only under special circumstances to analyze query phrases , to process structured text samples of a certain kind, [7,15], or finally to process texts in severely restricted topic areas.

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. Biology is a vast subject containing many subdivisions, topics, and disciplines.
This volume consists of a collection of current studies on free electron lasers. Free
Electron Lasers covers the analysis of fundamentals and questions of design of these
devices functioning from the infrared to ultraviolet or xuv wavelength regimes. In
addition to the comparison with conventional lasers, analyses of some related topics
concerning near-field and cavity electrodynamics, compact and table-top
arrangements and strong radiation–induced exotic states of matter are presented.
The goal of Aspatore Business Reviews (Aspatore Business Review, Aspatore Technology Review, Aspatore Marketing Review, Aspatore Entrepreneurial Review) are to bring you the most important, condensed business intelligence
from industry insiders on a range of different topics affecting every executive, expanding your breadth of knowledge and enabling you to innovate and outperform.
It is with great sense of gratitude and humility I take this blessed moment to offer this Seventh Edition of Piping Handbook. The challenge presented by the success of the Sixth Edition, coupled with our objective to enhance its reference value and widen its scope, motivated us to reach out and draw upon the recognized expertise on piping related topics not covered in the Sixth Edition.
In Chapter 2 and the chapters in Part III, you learned
that Active Directory domains are modeled on Internet
domains. You also learned that Windows 2000 networks rely
on TCP/IP as the network protocol of choice. In order to
resolve Windows 2000 domain controllers and many other
hosts running Windows 2000 services, you need to fully
understand and be able to configure Domain Name Service
(DNS). This chapter explains the services you can use to
This is a survey paper on Quality-of-Service(QoS) based routing. In this paper, we first introduce the
concept of Quality-of-Service and its background. Second, we discuss the concepts of QoS-based
routing, its objectives and main issues. After that, several types of QoS based routing algorithms are
compared, and the advantages and disadvantages of each type discussed. Then, the relations between
QoS based routing and some relevant techniques are studied, including traffic engineering, high level
admission control, resource reservation protocols(e.g.
