[ Team LiB ] Recipe 4.10 Updating a DataSet with a Many-to-Many Relationship Problem You have a DataSet that contains two tables that have a many-to-many relationship between them using a third junction table.
[ Team LiB ] Recipe 10.11 Creating DataSet Relationships from SQL Server Relationships Problem You need to create relationships between DataTable objects within your DataSet at runtime based on the relationships that are defined in your SQL Server database.
[ Team LiB ] Recipe 6.8 Creating Constraints, PrimaryKeys, Relationships Based on Multiple Columns Problem You need to create a constraint, primary key, or a relationship between two tables in a DataSet using more than one column. Solution Use the System.Data.
Sociolinguists have long argued that social context influences language use in all manner of ways, resulting in lects 1 . This paper explores a text classification problem we will call lect modeling, an example of what has been termed computational sociolinguistics. In particular, we use machine learning techniques to identify social power relationships between members of a social network, based purely on the content of their interpersonal communication.
The traditional hierarchical structure of cellular networks has led
to deployment models which are heavily centralized. Mobility
management with centralized mobility anchoring in existing
hierarchical mobile networks is quite prone to suboptimal routing and
issues related to scalability. Centralized functions present a
single point of failure, and inevitably introduce longer delays and
higher signaling loads for network operations related to mobility
We address the rating-inference problem, wherein rather than simply decide whether a review is “thumbs up” or “thumbs down”, as in previous sentiment analysis work, one must determine an author’s evaluation with respect to a multi-point scale (e.g., one to ﬁve “stars”). This task represents an interesting twist on standard multi-class text categorization because there are several different degrees of similarity between class labels; for example, “three stars” is intuitively closer to “four stars” than to “one star”.
There are many possible different semantic relationships between nominals. Classiﬁcation of such relationships is an important and difﬁcult task (for example, the well known noun compound classiﬁcation task is a special case of this problem). We propose a novel pattern clusters method for nominal relationship (NR) classiﬁcation. Pattern clusters are discovered in a large corpus independently of any particular training set, in an unsupervised manner. Each of the extracted clusters corresponds to some unspeciﬁed semantic relationship. ...
We translate sentence generation from TAG grammars with semantic and pragmatic information into a planning problem by encoding the contribution of each word declaratively and explicitly. This allows us to exploit the performance of off-the-shelf planners. It also opens up new perspectives on referring expression generation and the relationship between language and action.
Systemic grammar has been used for AI text generation work in the past, but the Implementations have tended be ad hoc or inefficient. This paper presents an approach to systemic text generation where AI problem solving techniques are applied directly to an unadulterated systemic grammar. This approach is made possible by a special relationship between systemic grammar and problem solving: both are organized primarily as choosing from alternatives. The result is simple, efficient text generation firmly based in a linguistic theory. ...
After completing this chapter, students will be able to: Database design process, what is ER Model? And why? A sample database application, ER Model Concepts, ER diagram and naming conventions, alternative diagrammatic notations, problems with ER models. Inviting you to refer.
Care for pregnant women differs fundamentally from most other medical
endeavours. ‘Routine’ care during pregnancy and birth interferes in the
lives of healthy people, and in a process which has the potential to be
an important life experience. It is diffi cult to measure the extent to which
our efforts may, for example, disturb the development of a confi dent,
nurturing relationship between mother and baby. The harmful effects we
measure in randomised trials are limited to those we have predicted may
The classic text on helicopter aerodynamics, "Aerodynamics of the Helicopter" has been in continuous print for over fifty years. Clearly written and well illustrated, the book focuses on fundamental physical relationships without a highly complex mathematical development. The emphasis on fundamentals makes the book an ideal - indeed, necessary - first step towards more advanced study.
This coaching toolkit contains a selection of forms, models and exercises,
and an explanation of how and when to use them. We have also included a
chapter on setting up the coaching relationship, which provides valuable
resources on managing the coaching relationship and your own continuous
The toolkit is designed to be used like a reference document so that you
can dip into the topic you need when you need it. Each tool contains an
overview and model diagram so that you get both the words and the big
Even those who ﬁnd algebra easy are stumped by word problems (also
called ‘‘applications’’). In this book, word problems are treated very care-
fully. Two important skills needed to solve word problems are discussed
earlier than the word problems themselves. First, you will learn how to
ﬁnd quantitative relationships in word problems and how to represent
them using variables. Second, you will learn how to represent multiple quan-
tities using only one variable.
A detailed empirical study of how small business owners finance their
enterprises, this volume compares the experiences of women with
those of men. The author redresses an over-reliance on subjective
and anecdotal evidence of discrimination in this area with a controlled
study of forty matched pairs of male/female owners, and their
strategies for raising finances.
The book finds considerable similarities between female and male
entrepreneurs in the type and amount of finance used in the business.
Everyone keeps data. Big organizations spend millions to look after their payroll, customer, and transaction
data. The penalties for getting it wrong are severe: businesses may collapse, shareholders and customers lose
money, and for many organizations (airlines, health boards, energy companies), it is not exaggerating to say that
even personal safety may be put at risk. And then there are the lawsuits. The problems in successfully designing,
installing, and maintaining such large databases are the subject of numerous books on data management and
Elements of present-day sea use management have evolved over a long
period. Basic to these are the principles of freedom of the seas, open access
to resources, and sectoral management. There is, however, a necessary
corrective to this Euro-centric view when the relationships between people
and the marine environment are examined in several other cultures. Open
access in Western society has experienced more recent restrictions as
resource scarcities have arisen and new technological capacities have
Cigarette smokers were 2.7 times more likely to have
respiratory diseases than those of non-smokers. Similarly
consumption of alcohol and use of non-smoked tobacco
were found to be risk factors of hypertension.
BMI more than 25 was risk factor for hypertension
and diabetes. On the other hand risk of respiratory
diseases and cataract increased below a BMI of 18.5.
Risk for musculoskeletal problems was found to be
higher in both extremes of physical status. The higher
risk of diseases to the both extremes of BMI suggests a U-
shaped relationship of diseases with BMI. BMI less 18.
Re-engaging with the Pure Theory of Law developed by Hans Kelsen and the
other members of the Viennese School of Jurisprudence, this book looks at the
causes and manifestations of uncertainty in international law. It considers both
epistemological uncertainty as to whether we can accurately perceive norms in
international law, and ontological problems which occur inter alia where two or
more norms conﬂict.
To gain a better understanding of the possible role of credit in improving house-
hold food security and alleviating poverty in Malawi, in November 1994 the Inter-
national Food Policy Research Institute and the Department of Rural Development,
Bunda College of Agriculture, University of Malawi, initiated a research program on
rural financial markets and household food security in Malawi. The main objective
of the research program was to analyze the determinants of access to credit in Malawi
and its impact on farm and nonfarm income and on household food security.
