  • We describe the early stage of our methodology of knowledge acquisition from technical texts. First, a partial morpho-syntactic analysis is performed to extract "candidate terms". Then, the knowledge engineer, assisted by an automatic clustering tool, builds the "conceptual fields" of the domain. We focus on this conceptual analysis stage, describe the data prepared from the results of the morpho-syntactic analysis and show the results of the clustering module and their interpretation.

  • A variable declared with the const modifier cannot have its value changed during the execution of your program. Thus, a const “variable” isn’t really variable! You can give a variable declared as const an initial value, however. For example, const int max_users = 9; creates an int variable called max_users that contains the value 9. This variable can be used in expressions like any other variable, but its value cannot be modified by your program.

  • Built-In Database Objects In addition to creating the database files, several other structures are created. Data dictionary: Contains descriptions of the objects in the database Dynamic performance tables: Contains information used by the database administrator (DBA) to monitor and tune the database and instance PL/SQL packages: Program units adding functionality to the database. These packages are created when the catproc.sql script is run after the CREATE DATABASE command. PL/SQL packages will not be discussed within the scope of this course.

  • The simplest way to think of Oracle’s implementation of read consistency is to imagine each user operating a private copy of the database, hence the multiversion consistency model. Read Consistency, Undo Records, and Transactions To manage the multiversion consistency model, Oracle must create a read-consistent set of data when a table is queried (read) and simultaneously updated (written). When an update occurs, the original data values changed by the update are recorded in the database undo records.

  • The Layered Domain Class system (LDC) is an experimental natural language processor being developed at Duke University which reached the prototype stage in M a y of 1983. Its primary goals are (I) to provide English-language retrieval capabilities for structured but unnormaUzed data files created by the user, (2) to allow very complex semantics, in terms of the information directly available from the physical data file; and (3) to enable users to customize the system to operate with new types of data. In this paper we shall discuss (a) the types of modifiers LDC provides for; (b) h o...

  • This paper proposes a semi-supervised boosting approach to improve statistical word alignment with limited labeled data and large amounts of unlabeled data. The proposed approach modifies the supervised boosting algorithm to a semisupervised learning algorithm by incorporating the unlabeled data. In this algorithm, we build a word aligner by using both the labeled data and the unlabeled data. Then we build a pseudo reference set for the unlabeled data, and calculate the error rate of each word aligner using only the labeled data.

  • The EViews workfile is defined as a file in EViews, which provides many convenient visual ways, such as (i) to enter and save data sets, (ii) to create new series or variables from existing ones, (iii) to display and print series and (iv) to carry out and save results of statistical analysis, aswell as each equation of the models applied in the analysis.By using EViews, each statistical model that applied previously could be recalled and modified easily and quickly to obtain the best fit model, based on personal judgment using an interactive process.

  • At its heart, jQuery does something that sounds pretty dull: it lets you modify the contents of HTML documents by manipulating the model that the browser creates when it processes the HTML (known as DOM manipulation, as I’ll explain later). If you are reading this, you have probably already done some DOM manipulation, either using another JavaScript library or even using the built-in API that most modern web browsers support, and you have picked up this book because you want to do it in a better way....
