Natural language processing (NLP) is a field that helps humans communicate with computers naturally. It is a shift from the era when humans had to “learn” to use computers to computers being trained to understand humans. It is a branch of artificial intelligence (AI) that deals with language. The field dates back to the 1950s when a lot of research was

We have previously stated that all variables need be declared. This means that their names are introduced in the heading of the program. In addition to introducing the name (and thereby enabling a compiler to detect and indicate misspelled identifiers), declarations have the purpose of associating a data type with each variable.

The ability to divide data into different types is one of the most important features of modern programming languages. It enables you to work with relatively complex objects instead of the more mundane objects that the computer manipulates at its lowest level. You can deal with integers, characters, and floating-point numbers, all of which are familiar

On the Semantics of “Data Type”
SIAM Journal on Computing, 1979This paper considers the general problem of specifying the meaning of programming languages which include "data type definition facilities". The fundamental question posed in attempting to define such languages is: "what meaning should be given to a data type definition," or more simply, "what does data type mean?".

Acta Informatica, 2006
The use of abstraction in the context of abstract data types, is investigated. Properties to be checked are formulas in a first order logic under Kleene's 3-valued interpretation. Abstractions are defined as pairs consisting of a congruence and a predicate interpretation. Three types of abstractions are considered,??, ?? and ?0,1?, and for each of them

The most important part of a visualization of data is the data themselves. If it does not show the data clearly, a visualization can be pretty, interesting, technically well executed, and all kinds of other good things, but it fails in its basic task. In this chapter we will look at data, and time-based data in particular, with a view to understanding ...

ACM SIGAPL APL Quote Quad, 1989
This paper describes a form of data typing implemented in APL. By contrast with conventional data typing, which basically specifies a storage format for a data type, it is a means of specifying the set of logical values that a variable is to be permitted to take. To assign a data type, a new copula analogous to value-assign is used. Hence only a single

Programs operate on data. It is thus natural to start our considerations of how to think about programs by a discussion of how to think about data types. For this purpose, we do not really need to know how the objects of a type are concretely represented (such representations have been discussed in Chap.

In the previous chapter, we discussed how to location-enable application data and how to organize geographic data into multiple tables, each containing SDO_GEOMETRY columns. In this chapter, we focus on storing and modeling different types of location information using the SDO_GEOMETRY data type in Oracle. The SDO_GEOMETRY type can store a wide variety
