Query Syntax

  • We develop a novel approach to the semantic analysis of short text segments and demonstrate its utility on a large corpus of Web search queries. Extracting meaning from short text segments is difficult as there is little semantic redundancy between terms; hence methods based on shallow semantic analysis may fail to accurately estimate meaning. Furthermore search queries lack explicit syntax often used to determine intent in question answering.

  • CHAPTER 4 ■■■ Querying the EDM You have spent the previous two chapters creating and exploring an Entity Data Model. Chapter 2 discussed the different ways an EDM can be created, and Chapter 3 explored the many facets of the EDM both internally and externally. It is now finally time to write some code. This chapter will discuss how to write queries against the EDM by using the LINQ-to-Entities syntax and the Entity SQL syntax, both provided by the Entity Framework. This chapter will also discuss the difference between query syntax and method syntax and when you might use one over the...

  • C # programmers at any level need to learn about LINQ (Language-Integrated Query), Microsoft’s breakthrough technology for simplifying and unifying data access from any data source. With LINQ you can write more elegant and flexible code, not just to access databases and files but also to manipulate data structures and XML. LINQ for Visual C# 2008 is a short guide to the major features of LINQ. It thoroughly covers LINQ to Objects, LINQ to SQL, LINQ to DataSet, and LINQ to XML. For instance, you’ll learn to...

  • In the previous chapter, I introduced you to LINQ. I provided some examples to whet your appetite, and shared some premature tips. You may be perplexed though by some of the syntax. If so, it is probably because the C# you witnessed in that chapter is new and improved. The reason for the C# language upgrade is that C# 2.0 just didn’t have the muscle to pull off LINQ. In this chapter, I introduce you to the more powerful C# 3.0.

  • XQuery can be a challenging topic to teach. There is only enough time to cover what it is, what it can do, and its basic syntax, but not in any depth. This module leaves the detailed coverage of XQuery for later courses. Just as Course 1913A, Exchanging and Transforming Data Using XML and XSLT, is a fiveday course on Extensible Stylesheet Language Transformations (XSLT), it is possible to devote a full five-day course to XQuery after it is fully specified and achieves W3C Recommendation status.

  • There are only three basic constructs in Prolog: facts, rules, and queries. A collection of facts and rules is called a knowledge base (or a database) and Prolog programming is all about writing knowledge bases. That is, Prolog programs simply are knowledge bases, collections of facts and rules which describe some collection of relationships that we find interesting. So how do we use a Prolog program? By posing queries. That is, by asking questions about the information stored in the knowledge base...

  • Since the release of the Microsoft .NET Framework in July 2000, the C# programming language has gone through a few iterations to its latest version, 3.0. Over the years, the C# language has gained a lot of followers, partly due to its syntax, which is familiar to Java and C programmers. The clear syntax of the language made it easy to learn, and it ’ s a popular choice for beginning programmers. In addition, the C# language is gaining a lot of traction in the Visual Basic camp, especially among VB6 programmers, who needed to move to .NET and did not want to learn a...

  • This section describes characteristics of the Wisconsin household population subgroups for whom health statistics are presented in this report. All of the characteristics described here are estimates from the 2008 Family Health Survey weighted data. The Family Health Survey is considered to be representative of all people who live in Wisconsin households. Survey results can be used to describe household residents, keeping in mind that survey estimates will differ from results of a complete count, such as a census.

  • Real asset investors also need a longer investment horizon, as investments in real assets normally require longer commitment of capital. Ship funds typically have a life of 15 to 20 years; aircraft funds more than 15 years. From the investor's point of view, it is therefore important to be able to assess the potential of the investment vehicle reliably. In addition, private investors mainly invest larger amounts. In 2011, the average subscription for investments in closed-end funds across all asset classes in Germany was EUR 30,575 (up from just over EUR 26,000 in 2010).

  • This paper presents recent extensions to Poliqarp, an open source tool for indexing and searching morphosyntactically annotated corpora, which turn it into a tool for indexing and searching certain kinds of treebanks, complementary to existing treebank search engines. In particular, the paper discusses the motivation for such a new tool, the extended query syntax of Poliqarp and implementation and efficiency issues.

  • Language-Integrated Query (LINQ) is a set of features introduced in Visual Studio 2008 that extends powerful query capabilities to the language syntax of C# and Visual Basic. LINQ introduces standard, easily-learned patterns for querying and updating data, and the technology can be extended to support potentially any kind of data store. Visual Studio includes LINQ provider assemblies that enable the use of LINQ with .NET Framework collections, SQL Server databases, ADO.NET Datasets, and XML documents. What is Linq?...
