  • Expert Indexing in Oracle Database 11g is about the one database structure at the heart of almost all performance concerns: the index. Database system performance is one of the top concerns in information technology today. Administrators struggle to keep up with the explosion of access and activity driven by the proliferation of computing into everything from phones to tablets to PCs in our increasingly connected world.

  • This paper introduces an indexing method based on static analysis of grammar rules and type signatures for typed feature structure grammars (TFSGs). The static analysis tries to predict at compile-time which feature paths will cause unification failure during parsing at run-time. To support the static analysis, we introduce a new classification of the instances of variables used in TFSGs, based on what type of structure sharing they create. The indexing actions that can be performed during parsing are also enumerated. ...

  • In this paper we present a supervised method for back-of-the-book index construction. We introduce a novel set of features that goes beyond the typical frequency-based analysis, including features based on discourse comprehension, syntactic patterns, and information drawn from an online encyclopedia. In experiments carried out on a book collection, the method was found to lead to an improvement of roughly 140% as compared to an existing state-of-the-art supervised method.

  • This paper describes a parser which generates parse trees with empty elements in which traces and fillers are co-indexed. The parser is an unlexicalized PCFG parser which is guaranteed to return the most probable parse. The grammar is extracted from a version of the PENN treebank which was automatically annotated with features in the style of Klein and Manning (2003). The annotation includes GPSG-style slash features which link traces and fillers, and other features which improve the general parsing accuracy. ...

  • This paper defines multiset-valued linear index grammar and unordered vector grammar with dominance links. The former models certain uses of multisetvalued feature structures in unification-based formalisms, while the latter is motivated by word order variation and by "quasi-trees", a generalization of trees. The two formalisms are weakly equivalent, and an important subset is at most context-sensitive and polynomially parsable.

  • Automatic image annotation is an attractive approach for enabling convenient access to images found in a variety of documents. Since image captions and relevant discussions found in the text can be useful for summarizing the content of images, it is also possible that this text can be used to generate salient indexing terms. Unfortunately, this problem is generally domainspecific because indexing terms that are useful in one domain can be ineffective in others.

  • Feature selection is to find useful and relevant features from an original feature space to effectively represent and index a given dataset. It is very important for classification and clustering problems, which may be quite difficult to solve when the amount of attributes in a given training data is very large.

  • Optical devices in communication and computation have a significant impact on our daily life, although we may not even be aware of their existence, as in case of inter-continent fiber cables that connect people around the world, making it a global village. Novel nanoscale structures have demonstrated a wide range of unique features; therefore have became a hot research topic. Not only that the novel structural materials are used in biomedical therapy, but also the nature inspires the design of innovative optical structures....

  • The obvious common feature of properties and indexers is that they both use get and set accessor syntax. This module does not cover the more advanced aspects of properties and indexers, such as their use in interfaces or their use with virtual, abstract, override, and new modifiers. After completing this module, students will be able to: Create properties to encapsulate data within a class. Define indexers to use objects with array-like notation.

  • The universal UDF in this case is called SAS_SCORE. This UDF is slightly different in that it can take a table or result set name as input, and the output is a result set. Call this a table UDF (compared to a scalar UDF like SAS_PUT UDF, which outputs a single value). The input parameter list of the SAS_SCORE UDF varies according to the DBMS and the model being executed. Regardless, the input parameter list of SAS_SCORE can be broken into two sets: the name of the scoring function to be run and the table or result set containing the...

Hassan (2003) employed Johansen’s (1988, 1991, 1992b) and Johansen and Juselius’ (1990) multivariate cointegration techniques to test for the existence of long-term relationships between share prices in the Persian Gulf region.
