Survey On Building A Database Driven Reverse DictionaryEditor IJMTER
Reverse dictionaries are widely used for a reference work that is organized by concepts,
phrases, or the definitions of words. This paper describe the many challenges inherent in building a
reverse lexicon, and map drawback to the well known abstract similarity problem The criterion web
search engines are basic versions of system; they take benefit of huge scale which permits inferring
general interest concerning documents from link information. This paper describe the basic study of
database driven reverse dictionary using three large-scale dataset namely person names, general English
words and biomedical concepts. This paper analyzes difficulties arising in the use of documents
produced by Reverse dictionary.
AntConc is a freeware corpus analysis toolkit designed for use in technical writing classrooms. It has a small memory footprint and is compatible with Windows, Linux, and Unix operating systems. AntConc provides several text analysis tools including concordance, keyword lists, word clusters, and original file viewing. Users can perform complex searches using regular expressions and wildcards. Search results can be sorted and formatted for copying or saving. However, AntConc is best suited for small specialized corpora and has limited statistics and annotation handling capabilities.
This document discusses key concepts in programming languages including names, keywords, variables, and binding. It defines names as strings that identify entities, noting conventions like starting with letters. Keywords and reserved words are discussed, with keywords being redefinable and reserved words not allowed as names. Variables are defined by their name, address, value, type, lifetime and scope. Binding is the association between an attribute and entity, which can be static or dynamic.
This document defines and summarizes key terms in corpus linguistics. It discusses bootstrapping, the Brill tagger, competence-performance dichotomy, computational linguistics, computer assisted language learning, corpus linguistics, extensible markup language, Penn Treebank, Kolhapur Corpus, Hyderabad Corpus, Text Encoding Initiative, Unicode, Linguistic Data Consortium, and alignment.
This document defines and describes various terms and concepts related to corpus linguistics and natural language processing. It defines acronyms for various corpora and projects. It also defines key concepts like alignment, annotation, ambiguity, balanced corpora, concordancing, part-of-speech tagging, and probabilistic tagging using n-grams.
Presented by Christoph Goller, Chief Scientist, IntraFind Software AG
If you want to search in a multilingual environment with high-quality language-specific word-normalization, if you want to handle mixed-language documents, if you want to add phonetic search for names if you need a semantic search which distinguishes between a search for the color "brown" and a person with the second name "brown", in all these cases you have to deal with different types of terms. I will show why it makes much more sense to attach types (prefixes) to Lucene terms instead of relying on different fields or even different indexes for different kinds of terms. Furthermore I will show how queries to such a typed index look and why e.g. SpanQueries are needed to correctly treat compound words and phrases or realize a reasonable phonetic search. The Analyzers and the QueryParser described are available as plugins for Lucene, Solr, and elasticsearch.
Detailed presentation on various analytical tools widely used in Corpus Linguistics for corpora analysis including WORDCRUNCHER, LEXA, CWB , TACT, MICROCONCORD etc.
Anti-plagiarism tools for our repositoriesJan Mach
Presentation focuses on a test and a comparative analysis of systems for detecting duplicates (so-called anti-plagiarism systems) used for the repositories of higher education theses and dissertations in the CR. A text corpus containing the most frequent sources of plagiarism was created for the needs of the test, and the modifications made by plagiarists were simulated.
The success of duplicity detection by the most important anti-plagiarism systems was verified experimentally, and a comparative analysis and verification of stipulated hypotheses were performed. The evaluation was also performed on the author’s own prototype application
using the Google search engine.
Information retrieval systems use indexes and inverted indexes to quickly search large document collections by mapping terms to their locations. Boolean retrieval uses an inverted index to process Boolean queries by intersecting postings lists to find documents that contain sets of terms. Key aspects of information retrieval systems include precision, recall, and ranking search results by relevance.
Realization of natural language interfaces usingunyil96
The document discusses research on using lazy functional programming (LFP) to build natural language interfaces (NLIs). LFP involves delaying evaluation of function arguments until needed. Over 45 researchers have investigated using LFP for NLI design and implementation due to similarities between some linguistic theories and LFP theories. The research has resulted in over 60 papers on using LFP for natural language processing tasks like syntactic and semantic analysis. The paper provides a comprehensive survey of this research area at the intersection of computer science and computational linguistics.
The task of keyword extraction is to automatically identify a set of terms that best describe the document. Automatic keyword extraction establishes a foundation for various natural language processing applications: information retrieval, the automatic indexing and classification of documents, automatic summarization and high-level semantic description, etc. Although the keyword extraction applications usually work on single documents (document-oriented task), keyword extraction is also applicable to a more demanding task, i.e. the keyword extraction from a whole collection of documents or from an entire web site, or from tweets from Twitter. In the era of big-data, obtaining an effective and efficient method for automatic keyword extraction from huge amounts of multi-topic textual sources is of high importance.
We proposed a novel Selectivity-Based Keyword Extraction (SBKE) method, which extracts keywords from the source text represented as a network. The node selectivity value is calculated from a weighted network as the average weight distributed on the links of a single node and is used in the procedure of keyword candidate ranking and extraction. The selectivity slightly outperforms an extraction based on the standard centrality measures. Therefore, the selectivity and its modification – generalized selectivity as the node centrality measures are included in the SBKE method. Selectivity-based extraction does not require linguistic knowledge as it is derived purely from statistical and structural information of the network and it can be easily ported to new languages and used in a multilingual scenario. The true potential of the proposed SBKE method is in its generality, portability and low computation costs, which positions it as a strong candidate for preparing collections which lack human annotations for keyword extraction. Testing of the portability of the SBKE was tested on Croatian, Serbian and English texts – more precisely it was developed on Croatian News and ported for extraction from parallel abstracts of scientific publication in the Serbian and English languages.
The constructed parallel corpus of scientific abstracts with annotated keywords allows a better comparison of the performance of the method across languages since we have the controlled experimental environment and data. The achieved keyword extraction results measured with an F1 score are 49.57% for English and 46.73% for the Serbian language, if we disregard keywords that are not present in the abstracts. In case that we evaluate against the whole keyword set, the F1 scores are 40.08% and 45.71% respectively. This work shows that SBKE can be easily ported to new a language, domain and type of text in the sense of its structure. Still, there are drawbacks – the method can extract only the words that appear in the text.
The document discusses various techniques for improving searches, including using search engines, databases, phrases in quotes, synonyms, Boolean operators, and advanced search options. It explains that search engines can provide quick access to information but may also provide unreliable or unrelated results, while databases contain focused, reliable information. The document outlines techniques like using phrases in quotes, word variations, and Boolean operators like and, or, and not to improve search results. It also describes using the "within" operator and taking advantage of advanced search modes.
This document provides guidance on information retrieval and literary searches. It outlines search purposes such as improving search quality, preparing for assignments, and understanding market needs. It then describes how to begin a search by defining topics, using reference sources to define terms, and forming search strategies using Boolean operators. Examples of search strategies are provided. The document also discusses searching different fields such as electronic resources, databases, and print materials. It provides tips for using search tools like quotation marks, wildcards, and truncation. Finally, it covers limiting search results by fields like subject, author, and document type.
This document summarizes an article about adaptive information extraction. It discusses how information extraction research has grown with the increasing availability of online text sources. However, one drawback of information extraction is its domain dependence. To address this, machine learning techniques have been used to develop adaptive information extraction systems that can be applied to new domains with less manual adaptation. The document provides an overview of information extraction and different machine learning approaches used for adaptive information extraction.
What are the basics of Analysing a corpus? chpt.10 RoutledgeRajpootBhatti5
This document provides an overview of the basics of analyzing a corpus through various techniques including frequency analysis, normalization, keyword analysis, and concordance analysis. It explains that frequency lists show how often words occur, normalization adjusts for corpus size differences, keyword analysis finds statistically significant words compared to a reference corpus, and concordance analysis displays keywords in context to better understand usage. The document serves as an introduction to basic corpus analysis methods and tools.
The document discusses different types of programming languages including declarative languages which are fact-oriented and do not consider sequence of execution, logic programming languages which use symbolic logic for programming, and functional languages which perform all computations through function applications. It also covers database languages which include DDL for data definition, DML for data manipulation like insertion and deletion, and DCL for data control through operations like commit and rollback.

Information retrieval chapter 2-Text Operations.pptSamuelKetema1
This document discusses text operations for information retrieval systems, including tokenization, stemming, and removing stop words. It explains that tokenization breaks text into discrete tokens or words. Stemming reduces words to their root form by removing affixes like prefixes and suffixes. Stop words, which are very common words like "the" and "of", are filtered out since they provide little meaning. The goal of these text operations is to select more meaningful index terms to represent document contents for retrieval tasks.
Terminology management as fitness v.2 itiITIRussia
The document discusses effective terminology management. It emphasizes that terminology must be managed in a unified storage system to ensure consistency across translations. A proper terminology management system allows terms to be gathered and stored independently of translation tools so they can be reused. It also highlights the importance of language-specific handling of terms and integrating terminology checking with quality assurance. The work of those managing terminology is essential to the process of making terms fit for localization of products.

It emphasizes that the cornerstone of Universal Design for Learning is flexibility, and teachers have flexible digital tools like text-to-speech, spelling and grammar checks, and highlighting features in the software they currently use everyday. It also provides examples of free tools and resources teachers can try to further support students' access to curriculum.
Enriching the semantic web tutorial session 1Tobias Wunner
The document discusses challenges and opportunities in natural language processing for the multilingual semantic web. It provides examples of how content on the web and semantic web exhibits linguistic variations within and across languages. It also summarizes several NLP applications like information extraction and natural language generation that utilize ontologies, and notes that these applications require domain and multilingual adaptation of lexicons and extraction rules. The document argues that efficient adaptation and sharing of linguistic resources between ontology-based NLP applications is needed.
The document describes language-independent methods for clustering similar contexts without using syntactic or lexical resources. It discusses representing contexts as vectors of lexical features and clustering them based on similarity. Feature selection involves identifying unigrams, bigrams, and co-occurrences based on frequency or association measures. Contexts can then be represented in first-order or second-order feature spaces and clustered. Applications include word sense discrimination, document clustering, and name discrimination.
Big Data Spain 2017 - Deriving Actionable Insights from High Volume Media St...Apache OpenNLP
Media analysts have to deal with with analyzing high volumes of real-time news feeds and social media streams which is often a tedious process because they need to write search profiles for entities. Python tools like NLTK do not scale to large production data sets and cannot be plugged into a distributed scalable frameworks like Apache Flink. Apache Flink being a streaming first engine is ideally suited for ingesting multiple streams of news feeds, social media, blogs etc.. and for being able to do streaming analytics on the various feeds. Natural Language Processing tools like Apache OpenNLP can be plugged into Flink streaming pipelines so as to be able to perform common NLP tasks like Named Entity Recognition (NER), Chunking, and text classification. In this talk, we’ll be building a real-time media analyzer which does Named Entity Recognition (NER) on the individual incoming streams, calculates the co-occurrences of the named entities and aggregates them across multiple streams; index the results into a search engine and being able to query the results for actionable insights. We’ll also be showing as to how to handle multilingual documents for calculating co-occurrences. NLP practitioners will come away from this talk with a better understanding of how the various Apache OpenNLP components can help in processing large streams of data feeds and can easily be plugged into a highly scalable and distributed framework like Apache Flink.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Microservice Teams - How the cloud changes the way we workSven Peters
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
