Advances in intelligent information and database systems by Tutut Herawan, Iwan Tri Riyadi Yanto, Mustafa Mat Deris

By Tutut Herawan, Iwan Tri Riyadi Yanto, Mustafa Mat Deris (auth.), Ngoc Thanh Nguyen, Radosław Katarzyniak, Shyi-Ming Chen (eds.)

The booklet contains 32 prolonged chapters that have been in keeping with chosen submissions to the poster consultation prepared through the second Asian convention on clever info and Database platforms (24-26 March 2010 in Hue, Vietnam). The booklet is geared up into 4 elements dedicated to info retrieval and administration, carrier composition and user-centered technique, information mining and data extraction, and computational intelligence, respectively. All chapters within the booklet speak about theoretical and useful matters concerning integration of man-made intelligence and database applied sciences to be able to strengthen new sessions of clever info platforms. Such mixture of man-made intelligence and database applied sciences is a quick turning out to be subfield of contemporary machine technology, vital as a result of consistent improvement of networked info platforms. New international multimedia platforms utilized by heterogeneous populations demand those advancements. The editors wish that the ebook will be important for graduate and PhD scholars of computing device technological know-how, in addition to for mature teachers, researchers and practitioners drawn to potent software of synthetic intelligence and database structures to fashionable details environments. it's the desire of the editors that readers of this quantity can locate many inspiring principles and influential useful examples and use them of their destiny work.

Mining of Massive Datasets

The recognition of the net and web trade presents many tremendous huge datasets from which info should be gleaned via information mining. This e-book specializes in sensible algorithms which were used to unravel key difficulties in information mining and which might be used on even the biggest datasets. It starts off with a dialogue of the map-reduce framework, an enormous device for parallelizing algorithms immediately.

Twitter Data Analytics (SpringerBriefs in Computer Science)

This short presents tools for harnessing Twitter facts to find options to complicated inquiries. The short introduces the method of gathering information via Twitter’s APIs and gives recommendations for curating huge datasets. The textual content offers examples of Twitter facts with real-world examples, the current demanding situations and complexities of creating visible analytic instruments, and the simplest suggestions to deal with those concerns.

Advances in Natural Language Processing: 9th International Conference on NLP, PolTAL 2014, Warsaw, Poland, September 17-19, 2014. Proceedings

This publication constitutes the refereed complaints of the ninth overseas convention on Advances in normal Language Processing, PolTAL 2014, Warsaw, Poland, in September 2014. The 27 revised complete papers and 20 revised brief papers awarded have been conscientiously reviewed and chosen from eighty three submissions. The papers are equipped in topical sections on morphology, named entity popularity, time period extraction; lexical semantics; sentence point syntax, semantics, and computing device translation; discourse, coreference solution, computerized summarization, and query answering; textual content class, details extraction and data retrieval; and speech processing, language modelling, and spell- and grammar-checking.

Analysis of Large and Complex Data

This booklet deals a picture of the state of the art in type on the interface among information, desktop technological know-how and alertness fields. The contributions span a vast spectrum, from theoretical advancements to sensible purposes; all of them proportion a robust computational part. the subjects addressed are from the subsequent fields: data and information research; desktop studying and data Discovery; information research in advertising; info research in Finance and Economics; info research in medication and the lifestyles Sciences; facts research within the Social, Behavioural, and health and wellbeing Care Sciences; information research in Interdisciplinary domain names; type and topic Indexing in Library and knowledge technological know-how.

We reduced the number of page writes from 1 to 4% in some hours of database activity. – Finding places where creating a functional index should be preferable. ) in many queries in WHERE clause. In many cases the query optimiser cannot use the index in such queries. To fix the problem we must rewrite the query and/or change the application or use the functional index or indexed 26 P. Lenkiewicz and K. Stencel computed columns. In some queries it allowed us to reduce the number of full scan type reads and speed up the queries significantly.

The mapping could be automatically done with high accuracy using the method proposed in [3]. Table1 gives some examples on mapping interrogative words to entity types, which are dependent on a query context. com/kim/ Ontology-Based Query Expansion with Latently Related Named Entities 45 Table 1. Mapping interrogative words to entity types Interrogative Word Who Which Where What NE Class Example Query Person Who was the first American in space?

There were also tables, which were classified incorrectly because of uncharacteristic queries in period of time, when the trace was collected. 5 Achieved Improvements Proposed method will be very good for large, intensively used and developed databases, in which manual, unsystematic methods of database tuning will not be successful. The big advantage of the method is that tuning recommendations can be obtained relatively fast, without large administrative work. It is also possible to use the method incrementally, by adding to the histogram results of analysis of traces taken later.
